State v. Pitts

The opinion of the Court was delivered by

STEIN, J.

Defendant, Darryl Pitts, was tried and convicted by a Camden County jury of the murders of Paul Reynolds and Stacey Elizardo. He was also convicted of several offenses based on events that occurred two days prior to the murders. Defendant was sentenced to death for the murder of Stacey Elizardo; he was sentenced to life imprisonment with thirty-years parole ineligibility for the murder of Paul Reynolds. Defendant appeals directly to this Court as of right. R. 2:2-l(a)(3). We affirm his convictions for murder and the related offenses.

The Attorney General acknowledges that defendant’s death sentence must be reversed because the trial court’s instructions to the jury on the balancing of aggravating and mitigating factors did not comply with the standards established in State *586v. Biegenwald, 106 N.J. 13, 53-67 (1987). We therefore set aside the death sentence and remand the matter to the trial court for a new sentencing proceeding.

Facts and Procedural History

The twelve-count indictment returned against the defendant included six counts charging offenses relating to the murders of Paul Reynolds and Stacey Elizardo on March 22, 1984, in Reynolds’ apartment. In the remaining six counts, defendant was charged with various crimes allegedly committed on March 20, 1984, at Elizardo’s townhouse in Lindenwold, New Jersey. Accordingly, the factual background essential to an understanding of the legal issues in this case commences with the events that occurred during the evening of March 20, 1984. The evidence produced at trial fully supports the following account of the material facts.

On March 20, 1984, defendant, an unemployed Vietnam War veteran, was in Elizardo’s townhouse. At her request, defendant was watching one of Elizardo’s two children while she and Paul Reynolds took her other child to the hospital. According to defendant, he and Elizardo had dated many times. They had been sexually intimate. Defendant acknowledged his deep affection for Elizardo.

In the course of the evening two other male friends of Elizardo visited her townhouse. The first was Paul Pencock, who had lived with Elizardo earlier that winter. He had come by to see her, and defendant invited him to stay and await her return. He testified that defendant expressed anger because Elizardo was out late with Reynolds.

Soon after Peneock’s arrival, Vincent Della Polla, another friend of Elizardo, called to speak to Brian Gallo who shared the townhouse with Elizardo and her children. Pitts, represent*587ing himself to be Gallo, invited Della Polio to the apartment. He arrived soon afterwards.

The three men discussed their feelings toward Elizardo while awaiting her return. Defendant stated that he loved her very much and questioned the other two about the depth of their affection for her. Pencock acknowledged that he also loved and cared about her; Della Polla told defendant that he cared for her but did not love her. Defendant’s response to Della Polla was that he “shouldn’t be here.”

As time passed defendant became increasingly angry at Elizardo’s failure to return home. Pitts blamed Reynolds for keeping her out late and said that he would “get” Reynolds. When Elizardo and Reynolds returned about 11:00 p.m., Pitts called her a “tramp” and demanded to know where she had been. Reynolds intervened and invited defendant into the living room to discuss his concerns, but defendant, glaring at Reynolds, did not leave the kitchen.

Defendant also made threatening statements to Elizardo, commenting that “it’s getting closer to midnight.” Elizardo told Della Polla that she interpreted defendant’s words to mean that she would die at twelve o’clock. Elizardo then demanded that everyone leave the apartment. Suddenly, defendant grabbed a kitchen knife and held it against Della Polla’s neck. He threatened to slit his throat, accusing Della Polla of having infected Elizardo with a venereal disease that she had subsequently transmitted to defendant. Della Polla pushed defendant away. Defendant then left the apartment with Pencock, who had offered to drive him home. Reynolds left at the same time, leaving Elizardo with Della Polla.

Pencock drove Pitts home and returned to Elizardo’s apartment. According to Della Polla, Pitts telephoned Elizardo several times and made threatening remarks. This prompted Della Polla to offer to take Elizardo to his house. She refused, stating that “nobody is going to throw me out of my own house.”

*588Shortly thereafter, defendant returned to the apartment and sat down at the kitchen table with Elizardo, Pencock, and Della Polla. Pitts was carrying a rifle with a pistol-type handle which he pointed at Della Polla saying, “We are going to talk.” Pencock then told Della Polla to leave, and Della Polla walked out of the apartment. Pitts followed him out, as did Pencock. Pitts, holding the gun with his finger on the trigger, said he was going to shoot Della Polla. Pencock intervened, standing between Pitts and Della Polla, who then got into his car and drove away.

Pitts returned to the apartment waving the rifle, and directed his anger at Elizardo, calling her a “tramp” and a “whore.” When Pencock attempted to take the rifle from defendant, it fell to the ground and discharged. Pencock picked up the weapon, removed the clip, which he placed in his pocket, and hid the rifle under the cushion of a couch. Subsequently, at defendant’s insistence, Pencock returned the rifle to him without the clip.

Defendant, Pencock, and Elizardo remained in the apartment until about 5:00 a.m., when Pencock awakened her and told her that he had to leave. Elizardo assured Pencock that she would be safe in the apartment with defendant. Defendant left Elizardo’s apartment the next morning. Pencock returned to Elizardo’s apartment late in the afternoon of March 21, bringing with him the gun clip that defendant had asked Elizardo to retrieve for him. Pencock stayed at the apartment overnight. On Thursday morning, March 22, Paul Reynolds arrived, and he and Elizardo left the apartment together.

That same morning Pitts asked James Gibbs, his downstairs neighbor, to drive him on a few errands. Defendant offered to pay for gasoline and assured Gibbs they would return within forty-five minutes. They first drove to the apartment of Patricia Woods, defendant’s former wife, but defendant observed that her car was not in the parking lot. They proceeded to a liquor store where Pitts purchased a six-pack of beer. Pitts *589drank half of a bottle of beer as they drove to Paul Reynolds’ apartment. Gibbs parked the car and waited while Pitts proceeded to Reynolds’ apartment. Outside the apartment door Pitts encountered Michael Sarich who was visiting Reynolds to repay a debt. According to Sarich, a woman’s shoes and coat were in plain view in Reynolds' living room. Sarich departed, leaving Reynolds and Pitts together in the apartment. The two quickly became engaged in a heated argument. Pitts, the only survivor of the ensuing encounter, has offered several different accounts of the events that followed.

In his first statement to police officers following his arrest, defendant attributed the murders of Reynolds and Elizardo to an unidentified male who was waiting at Reynolds’ apartment door when Pitts arrived for the purpose of buying some marijuana. According to Pitts, the assailant “freaked,” pulled out a knife, and stabbed Reynolds. He then stabbed Elizardo as she attempted to run from the apartment. Pitts said that his hands were smeared with blood when he attempted to render first aid. He denied responsibility for either homicide.

Defendant gave a second statement to the police at 2:10 a.m. on March 23, approximately an hour after he completed his first statement. In the second statement, Pitts acknowledged responsibility for both homicides. Pitts said that he and Reynolds argued about seven hundred dollars that Reynolds owed him.

They owed me. At that time they owed me seven hundred dollars and Paul’s been holding and holding and holding and he's been bullshitting me * * *.
* * * I tried to get [the money] from [Reynolds]. When he started getting shitty with me, that’s when I got shitty back. That’s when — what the fuck are you doing? I says, mother, I told you don’t fuck with me, and he did.

According to defendant, he then pulled out a black Army “survival” knife and cut Reynolds’ throat:

He was cut but it wasn’t severe enough but you can cut a human being and usually they’ll stay alive three minutes. That’s a known fact. According to you gentlemen, he was stabbed. All this is going on fast. This couldn’t have taken no more than ten, 15 seconds. When [Stacey] came out of the room, what the fuck you doing, jerkoff, and on and on and on. I said because my fucking money is not in my hand and it went on. That’s when I, you know, attacked her. * * *
*590[After Reynolds had fallen against the wall, Stacey] went into hysterics. And when the hysterics went down, that’s when I fucked up * * *.
I guess originally it started as a struggle because I grabbed her and I tried to cut her throat. I told you before, you can use [the combat knife for] cutting someone’s throat.

Defendant indicated that he twice attempted to cut Elizardo’s throat, but did not recall stabbing any other part of her body. He stated that he “took the pulse” of both victims, and determined that both were dead.

Both of defendant’s statements to the police were read to the jury during the guilt phase of the trial. When defendant testified at trial, he repudiated the explanation offered in his second statement to police that an argument over an unpaid debt provoked the homicides. Pitts testified at trial that he had gone to Reynolds’ apartment to buy marijuana. He saw Elizardo’s shoes and coat and asked to see her. Reynolds said that she was asleep, and indicated that she would not want to see Pitts. Pitts testified that he then accused Reynolds of encouraging Elizardo to engage in prostitution in order to earn money to pay for drugs that she purchased from Reynolds. According to Pitts, an argument erupted, the two shoved each other, and Reynolds demanded that Pitts leave. When he refused, Reynolds turned toward the bedroom and said that he was going to get a gun. Pitts then pulled out his knife and stabbed Reynolds. He described the assault as an “instantaneous like reflex.” While occupied with Reynolds, and in a “frenzied-type state of mind,” Pitts perceived an “image” behind him. According to Pitts’ trial testimony:

[W]hereas, that now which I know Stacy was behind me, it was just an image at that time that I wheeled around and I sliced Stacy with the knife at the time
* * * [W]hen I came back to my senses I had realized what I had done and Stacy was laying outside the apartment and Paul was laying inside the apartment and Stacy was in a puddle of blood and I lifted her up and I put her back into the apartment and then I went back downstairs and I ran downstairs and I got into James Gibbs’ car.

Pitts also testified that he loved Elizardo and was jealous of her relationships with other men. He explained that his second *591statement to the police, in which he falsely attributed the murders to an unpaid debt, was prompted by a reluctance to admit to the police that he killed Reynolds because of his feelings for Elizardo. During cross-examination, Pitts said that he had the combat knife with him in order to take it to his mother’s house, so that his son would not find it when he visited Pitts.

Dr. Gerald Cooke, a clinical and forensic psychiatrist who tested and evaluated the defendant, gave trial testimony that was corroborative of Pitts’s trial version of the homicides. He testified that although Pitts was not psychotic or out of touch with reality,

he has some tendency towards loss of control or increased emotional stimulation. * * * [He] has more of a tendency to lose control than the average person when he is stressed, particularly if those stresses fit into these particular dynamics I have mentioned, such as rejection by women, things of that nature.

Dr. Cooke also testified that Pitts “showed a continuing preoccupation with Vietnam.” Dr. Cooke reviewed his discussions with Pitts concerning his Vietnam service:

He was in combat in Vietnam and was wounded in combat. We talked about Vietnam. * * * He says that he felt that he accomplished more in one afternoon in Vietnam in a combat situation than he has done in his entire life since then, and I got a real sense that he feels like much of his life has been useless and without purpose since that time.

Dr. Cooke diagnosed defendant as having

a cyclothymic personality disorder. What that means is that he is an individual whose moods vary significantly over a time to a point where it disrupts his day-to-day functioning and at times he is maybe depressed significantly, and to[o] he may be hyperactive, manic.
This is a similar type of disorder, though [it] is not as severe as what people have referred to as manic depressive psychosis or manic depressive illness. He does not go to extremes as a manic depressive does, he does not lose day-to-day, at any rate, any kind of contact with reality the way a manic depressant might. But he has the same pattern in his behavior of having periods of days, weeks, months of depression and other periods where he is hyperactive, outgoing and shows his more impulsive and manicy sorts of behavior.
I also indicated that along with the cyclothymic personality disorder, superimposed on it he has a chronic anxiety disorder, and above-average level of anxiety on a chronic basis.

*592At trial, Dr. Cooke recounted the result of his interrogation of defendant concerning the homicides:

[He] doesn’t remember, he says, reaching for the knife; he remembers having a knife in his hand, but he doesn’t actually remember stabbing. He says he remembers wheeling around with somewhat of a slashing motion and does not remember any specific stabs after that. He says he does remember seeing blood and things of that nature.
ft***####
He also then tells me that out of the comer of his eye he saw what at some times he described as an image, as a person, didn’t know who it was, he says, didn’t know if it was a male or female but had a feeling very much like the feeling that he had when he was in Vietnam, “I have to win, I have to survive, I am under attack,” things of that nature.
I went into this with him in great detail; this is not a flashback into any specific incident, this is not like he is reliving a specific incident in Vietnam. I am not saying that. What I am saying, he had the general feeling under this stressful situation that he had had at times in Vietnam in just having to win, having to survive, having to strike out until there was no more motion around him. He said that he only afterwards realized that that was Stacy.
********
He told me he wheeled around and slashed at her, but then again not knowing it was her at that point and then again does not remember the stabbing itself. He does, he said something like he had a feeling he was hitting the person and he realized later that he must have been stabbing her.
He then said the next thing he knew, he saw her on the floor, knew it was her, there was blood everywhere. He said he experienced at that point, and this is a quote, “Like a stillness like in Vietnam after a firefight.” He said at that point he began to realize what he had done.

Based on this evaluation of defendant and the defendant’s account of the homicides, Dr. Cooke related his opinion about the defendant’s state of mind at the time of the murders:

[U]nder that situation he experienced some of that feeling from Vietnam, not a specific flashback, but a feeling in which he perceives himself to be in danger, perceives himself as having to strike out to protect himself in part.
But even more important, that he had an emotional response there, an impulsive emotional response, not a response where he stopped and thought and decided, “I will do this, I will do that,” but, rather, a loss of control under the influence of extreme emotions and what I would say, combining all that data, a rage reaction, a reaction in which his anger reached the point of rage, which I would define as an anger that goes out of control and an anger which interferes with the cognitive ability a person has, planning, judgment, recognizing consequences, deliberating, that in my opinion, he experiences such a loss of control.

*593Dr. Robert Segal, the Camden County Medical Examiner, testified that the deaths of both victims resulted from multiple stab wounds inflicted by a heavy-bladed knife with a single sharp edge and a square or blunted opposite edge, and that the Ka-Bar type knife offered into evidence by the State could have caused the wounds observed on the victims. Dr. Segal identified the following knife wounds on Reynolds’ body: (1) left eye and cheek; (2) under the neck and extending towards the left ear; (3) base of the neck; (4) left front of the chest near the left nipple; (5) left side of the back; (6) inner left forearm; (7) right side of the head above the ear, which penetrated through the scalp, skull, and brain to strike the bone at the bottom of the skull. Dr. Segal testified that wound (4), which cut the right lung and the aorta, was if “[u]ntreated * * * a uniformly fatal wound[;]” he adjudged this wound, however, to be “part of the cause of death,” which cause he identified as “multiple stab wounds of the head, neck, and trunk.” In addition, Dr. Segal found abrasions, or scrapes, “on the chest, on the right eyebrow and on the left shoulder area.”

From his examination of Elizardo’s body, Dr. Segal observed “multiple stab wounds and multiple scrap[e]s o[r] abrasions over practically all portions of the body. The major portion of the right leg is spared, most of the back is spared.” Specifically, the stab and slashing wounds were inflicted on: (1) the left cheek, continuing upwards to split the ear in half; (2) the throat, extending towards the ear; (3) the throat, also extending towards the ear; (4-6) three cuts on the left side of the head in the skull, two of which penetrated through the skull into the brain; (7-9) three stab wounds on the left side of the chest beginning beneath the left breast and extending to the side and downward; (10) back of the left shoulder; (11), (12) back of [left] arm; (13) [left] elbow; (14) back of [left] forearm; (15) index finger of left hand; (16) junction of left buttock and thigh; (17) lower left leg; (18) front of right arm; (19) above right elbow; (20) [right] forearm; (21) [right] hand; (22) and (23) midline of back of neck; (24) back of right shoulder. *594Internal examination revealed a fractured third left rib and right humerus, a cut aorta, a cut esophagus, cut lungs, and blood in her lungs.

Dr. Segal also testified that he could recall “no specific description of any of the wounds [on the bodies] that would indicate clear and unequivocal evidence that [it had been inflicted] postmortem.”

Defendant’s neighbor James Gibbs, who had driven Pitts to Reynolds’ apartment, gave testimony concerning the events that occurred after the homicides. He stated that he had heard screams from inside the apartment building. When Pitts returned to the car, he had blood on his hands and a knife concealed in his coat. He told Gibbs that Reynolds had “pulled a shotgun on him” and that he had killed Reynolds and Elizardo. According to Gibbs, Pitts said, “I cut her throat, you don’t have to worry about her.” When Gibbs questioned Pitts further about why the killings occurred, Pitts told Gibbs that “they owed me money.” Gibbs testified that Pitts grinned and said, “[s]ee what I mean about paybacks is a bitch.” Gibbs also noted that Pitts asked him if he would “stand up to these people if they question you and all.”

Gibbs then drove Pitts to his mother’s house in Hammonton. On the way, Pitts used beer to wash his hands of blood and threw some bloodstained papers out the car window. Pitts told Gibbs that he was going to bury his clothes and dispose of the knife. As he got out of Gibbs’ car, Pitts told Gibbs “[t]here will be a couple of thousand in this for you when it’s all over.”

Later that day, Gibbs went to the Pemberton police headquarters and gave a statement implicating defendant in the homicides. Defendant was apprehended by police at his apartment later that evening.

As noted above, supra at 586, defendant was named in a twelve-count indictment returned by a Camden County Grand Jury. Six counts related to the murder of Paul Reynolds and *595Stacey Elizardo and six counts concerned the events that occurred two days earlier at Elizardo’s townhouse.

At the conclusion of the guilt-phase of the trial, the trial court charged the jury on passion/provocation manslaughter, N.J.S.A. 2C:ll-4b(2), as a lesser-included offense of murder. See State v. Grunow, 102 N.J. 133 (1986). Defendant requested an instruction on imperfect self-defense, contending that his belief that his safety was endangered was relevant to the jury’s consideration of a passion/provocation manslaughter verdict. The trial court refused to charge the jury on imperfect self-defense.

Defendant was convicted on all counts of the indictment, including the murder of Paul Reynolds (N.J.S.A. 2C:ll-3(a)(2) and N.J.S.A. 2C:ll-3(c)); the murder of Stacey Elizardo (N.J. S.A. 2C:ll-3(a)(2) and N.J.S.A. 2C:ll-3(c)); hindering apprehension or prosecution (N.J.S.A. 2C:29-3(b)(l)); two counts of possession of a weapon, a knife, for an unlawful purpose (N.J.S.A. 2C:39-4(d)); false swearing (N.J.S.A. 28:2-2(a)); two counts of possession of a weapon, a handgun, for an unlawful purpose (N.J.S.A. 2C:39-4(a)); tampering with a witness (N.J.S.A. 2C:28-5(a)(2)); terroristic threats (N.J.S.A. 2C:12-3); aggravated assault by pointing a firearm (N.J.S.A. 2C:12-l(b)(4)); and unlawful possession of a handgun (N.J.S.A. 2C:39-5(b)).

In the penalty phase, the jury determined with respect to both homicides that the State had proved the existence of aggravating factor N.J.S.A. 2C:ll-3c(4)(c), that “[t]he murder was outrageously or wantonly vile, horrible or inhuman in that it involved torture, depravity of mind, or an aggravated battery to the victim[.]” The jury found that the State had not established the existence of a second aggravating factor in connection with the Reynolds murder, that “the defendant purposely or knowingly created a grave risk of death to another person in addition to the victim[.]” N.J.S.A. 2C:ll-3c(4)(b). With regard to the murder of Elizardo, the jury found that the State had not established the existence of a second aggravating factor, in *596connection with the Reynolds murder, that “[t]he murder was committed for the purpose of escaping detection, apprehension, trial, punishment, or confinement for another offense * * N.J.S.A. 2G:ll-3c(4)(f).

With respect to the murder of Paul Reynolds, the jury determined that the following mitigating factors existed:

(a) The defendant was under the influence of extreme mental or emotional disturbance insufficient to constitute a defense to prosecution; [N.J.S.A. 2C:11-3c(5)(a).]
(b) The victim solicited, participated in or consented to the conduct which resulted in his death; [N.J.S.A. 2C:ll-3c(5)(b).]
(f) The defendant has no significant history of prior criminal activity; [N.J. S.A. 2C:ll-3c(5)(f).]
(h) Any other factor which is relevant to the defendant’s character or record or to the circumstances of the offense. [N.J.S.A. 2C:ll-3c(5)(h).]

The jury rejected defendant’s proof of mitigating factor 2C:11-3c(5)(d) that “[t]he defendant’s capacity to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of the law was significantly impaired as the result of mental disease or defect or intoxication, but not to a degree sufficient to constitute a defense to prosecution.” The jury determined that the single aggravating factor was outweighed by the mitigating factors.

With regard to the murder of Elizardo, the jury found the following mitigating factors were established:

(a) The defendant was under the influence of extreme mental or emotional disturbance insufficient to constitute a defense to prosecution; [N.J.S.A. 2C:11-3c(5)(a).]
(f) The defendant has no significant history of prior criminal activity; [N.J. S.A. 2C:ll-3c(5)(f).]
(h) Any other factor which is relevant to the defendant’s character or record or to the circumstances of the offense; [N.J.S.A. 2C:ll-3c(5)(h).]

The jury determined that defendant had not established the existence of mitigating factor 2C:ll-3c(5)(b) (“[t]he victim solicited, participated in or consented to the conduct which resulted in his death”), or 2C:ll-3c(5)(d) (“[t]he defendant’s capacity to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of the law was significantly impaired as the result of mental disease or defect or intoxication, *597but not to a degree sufficient to constitute a defense to prosecution.”). The jury concluded that the aggravating factor was not outweighed by the mitigating factors. Accordingly, the trial court sentenced defendant to death for the murder of Stacey Elizardo.

Defendant was also sentenced to life imprisonment with thirty-years parole ineligibility for the murder of Paul Reynolds. In addition, defendant received concurrent sentences for the remaining, unmerged counts of the indictment: seven years for possession of a firearm for an unlawful purpose (N.J.S.A. 2C:39-4(a)); concurrent terms of four years each on count three, hindering apprehension (N.J.S.A. 2C:29-3(b)(l)), count seven, tampering with a witness (N.J.S.A. 2C:28-5(a)(2)), and count eight, terroristic threats (N.J.S.A. 2C:12-3), and concurrent terms of eighteen months each on count five, false swearing (N.J.S.A. 28:2-2(a)), and count nine, aggravated assault (N.J.S.A. 2C:12-l(b)(4)).1

Defendant challenges his convictions and death sentence on numerous grounds. We now consider each of defendant’s contentions.

II.

Constitutional Issues

Defendant contends that New Jersey’s capital punishment act, N.J.S.A. 2C:ll-3c to g, infringes on rights afforded him by the New Jersey Constitution. We addressed this contention in State v. Biegenwald, supra, 106 N.J. 13, 25-26 (1987), and State v. Ramseur, 106 N.J. 123, 166-97 (1987). We adhere to our conclusion that the death penalty statute does not violate *598either federal or state constitutional prohibitions against cruel and unusual punishment. U.S. Const, amends. VIII, XIV; N.J. Const, of 1947 art. I, para. 12. We also reject as meritless defendant’s assertion that the statute infringes on the rights guaranteed by Article I, paragraph 1 of the State Constitution.

Defendant also contends that the capital punishment act is unconstitutional because it does not authorize the jury to disregard the balancing of aggravating and mitigating factors mandated by the act and return a non-death verdict based on considerations of mercy. We considered and rejected a similar contention in State v. Ramseur, supra, where we held that an instruction that the jury “should decide the case on the evidence without any bias, prejudice or sympathy * * * ” did not violate a defendant’s constitutional rights, 106 N.J. 123, 296-99, citing California v. Brown, 479 U.S. 538, 107 S.Ct. 837, 93 L.Ed.2d 934 (1987). We also observed in Ramseur that the trial court’s charge “did not preclude the jury from considering all possible mitigating circumstances and such sympathy as those circumstances might inspire.” Ramseur, 106 N.J. at 299.

In this case, the trial court’s penalty-phase charge did not mention mercy or sympathy. As in Ramseur, the jury was free to consider and weigh any of the mitigating factors established by the defendant, in the context of any feelings of compassion, mercy or sympathy engendered by those mitigating factors. See State v. Rose, 112 N.J. 454, 544-45 (1988) (“The Court’s instruction * * * did not inhibit the jury from considering sympathy to the extent it may have been engendered by mitigating factors proved by defendant.”).

Defendant asserts that the jury must be free to render a verdict prompted by feelings of mercy unrelated to any mitigating factor recognized by the Act and unconstrained by the jury’s balancing of aggravating and mitigating factors. We reject that contention and conclude that the jury’s authority under the Capital Punishment Act to consider, in pronouncing sentence, feelings of mercy and sympathy inspired only by *599mitigating factors established by the evidence does not violate defendant’s constitutional rights.

III.

Guilt-Phase Issues

A. Defendant’s Severance Motion.

Defendant moved before trial to sever from the indictment all counts that were based on events that occurred at Stacey Elizardo’s residence on March 20, 1984, two days prior to the homicides. Defendant argued that it would be highly prejudicial for the capital murder offenses to be tried together with unrelated charges based on the events of March 20, asserting that the only connection between the homicide and pre-homicide counts was that the latter took place at the apartment of one of the victims. The State argued that the events of March 20, whether or not included as separate counts of the indictment, were relevant to prove defendant’s love for Stacey, his jealousy of other men she dated, and, particularly, his animosity toward the victim, Paul Reynolds. The trial court denied defendant’s motion to sever the challenged counts from the indictment, observing that it was

satisfied that the facts surrounding the two dates of March 20 culminating * * * with the homicides of March 22, are so interlocked, so part of the mosaic, as the prosecutor called it, that it would not be possible to tailor that evidence in such a way as to bring out statements and not bring out acts, and especially considering that the acts themselves are part and parcel of the State’s total case with intent to prove motive on the part of this defendant, and especially because it seems to me this is a series of events, a series of facts that begins on the 20th, is continued uninterrupted until it results in the homicides, that the chances are * * * that all facts of the March 20 episodes * * * are more than likely going to be coming into evidence in the homicide trials anyway.

We first look to Rule 3:7-6 to determine whether the challenged counts could properly be joined in the same indictment with the counts relating to the homicides. That Rule provides:

Two or more offenses may be charged in the same indictment or accusation in a separate count for each offense if the offenses charged are of the same or similar character or are based on the same act or transaction or on 2 or more *600acts or transactions connected together or constituting parts of a common scheme or plan. Relief from prejudicial joinder shall be afforded as provided by R. 8:15-2.

In this context, the critical phrase in Rule 3:7-6 is “if the offenses charged are * * * based on * * * 2 or more acts or transactions connected together * * The Rule’s phraseology is hardly self-explanatory. See 8 J. Moore, W. Taggart & J. Wicker, Moore’s Federal Practice, ¶ 8.05[3] (2d ed. 1988) (“[C]ourts have sometimes found it as difficult to determine when acts are ‘connected’ as when they are ‘the same.’ ”). In this case, however, the connection between the events of March 20 and the homicides is readily apparent. The testimony about the events of March 20 included references to a threat by defendant to “get” Reynolds for keeping Stacey out late, and to threats by defendant that were directed at Stacey. In addition, defendant threatened Stacey’s friend Della Polla by holding a knife to his throat, and later in the evening threatened his life with a sawed-off shotgun. The evidence of defendant’s jealousy and threats of violence toward other male friends of Stacey was clearly relevant to the issue of defendant’s intent and state of mind at the time of the homicides, and also was material to the State’s effort to establish defendant’s motive for the murders on March 22. The State’s entitlement to offer proof of motive is well settled. State v. Carter, 91 N.J. 86, 102 (1982). In our view, there clearly existed a connection between the events of March 20 and those of March 22 sufficient to authorize joinder of counts relating to both dates in a single indictment, in accordance with Rule 3:7-6. See State v. Briley, 53 N.J. 498, 503 (1969); State v. Begyn, 34 N.J. 35, 56-57 (1961); State v. Manney, 26 N.J. 362, 366 (1958); State v. Cole, 154 N.J.Super. 138, 142-43 (App.Div.1977), certif. denied, 78 N.J. 415 (1978).

Defendant also argues that the trial court abused its discretion in denying defendant’s severance motion, alleging significant potential for prejudice because of the consolidation of multiple offenses involving alleged acts of violence in a *601single indictment. Although joinder of offenses may be permissible under Rule 3:7-6, severance is authorized in the trial court’s discretion if joinder is likely to result in prejudice to the defendant. Rule 3:15-2(b) provides:

If for any other reason it appears that a defendant or the State is prejudiced by a permissible or mandatory joinder of offenses or of defendants in an indictment or accusation the court may order an election or separate trials of counts, grant a severance of defendants, or direct other appropriate relief.

Defendant claims substantial prejudice from joinder of the March 20 counts with the homicide counts. He asserts primarily that the very exposure of the jury to evidence of violent acts allegedly committed by defendant two days prior to the homicides necessarily created in the jurors’ minds an unfavorable impression of defendant. Defendant argues that joinder under these circumstances inevitably affected the jury’s ability to afford him a fair and impartial trial. Defendant’s contentions merit careful evaluation, particularly in a death-penalty prosecution. The potential for prejudice from joinder of multiple offenses in a single criminal trial was illuminated nearly fifty years ago by Judge Learned Hand:

There is indeed always a danger when several crimes are tried together, that the jury may use the evidence cumulatively; that is, that, although so much as would be admissible upon any one of the charges might not have persuaded them of the accused’s guilt, the sum of it will convince them as to all. This possibility violates the doctrine that only direct evidence of the transaction charged will ordinarily be accepted, and that the accused is not to be convicted because of his criminal disposition. Yet in the ordinary affairs of life such a disposition is a convincing factor, and its exclusion is rather because the issue is practically unmanageable than because it is not rationally relevant. When the accused’s conduct on several separate occasions can properly be examined in detail, the objection disappears, and the only consideration is whether the trial as a whole may not become too confused for the jury. [United States v. Lotsch, 102 F.2d 35, 36 (2d Cir.), cert. denied, 307 U.S. 622, 59 S.Ct. 793, 83 L.Ed. 1500 (1939).]

A trial court must be accorded ample discretion in determining whether to grant relief from joinder of offenses because of the potential for prejudice. State v. Briley, supra, 53 N.J. at 503; State v. Manney, supra, 26 N.J. at 368. A critical inquiry is whether, assuming the charges were tried *602separately, evidence of the offenses sought to be severed would be admissible under Evidence Rule 55 in the trial of the remaining charges. State v. Moore, 113 N.J. 239, 274 (1988); State v. Kent, 173 N.J.Super. 215, 220 (App.Div.1980); accord Drew v. United States, 331 F.2d 85, 90 (D.C.Cir.1964). Rule 55 precludes the admissibility of evidence of other crimes to prove defendant’s propensity toward criminal conduct, State v. Kociolek, 23 N.J. 400, 419 (1957), but the Rule expressly permits such evidence to prove other facts genuinely in issue, such as motive or intent. Evid.R. 55; State v. Stevens, 115 N.J. 289, 300 (1989); State v. Garfole, 76 N.J. 445, 450 (1978), appeal after remand, 80 N.J. 350 (1979).

Whether the March 20 counts were tried separately or consolidated for trial with the homicide counts, evidence concerning the critical events of March 20 would have been admissible in the trial of the murder charges. Evidence of defendant’s jealousy and hostility toward the victim, Paul Reynolds, and toward Della Polla, as well as evidence that defendant threatened to harm Della Polla with a knife and shotgun would have been admissible in the homicide prosecution to prove defendant’s state of mind and motive, see State v. Breakiron, 210 N.J.Super. 442, 460-61 (App.Div.1986), rev’d on other grounds, 108 N.J. 591 (1987); State v. Slocum, 130 N.J.Super. 358, 362-63 (App.Div.1974), issues that were sharply contested at trial. Cf. State v. Stevens, supra, 115 N.J. at 301 (Other-crime evidence can be admitted to prove any fact genuinely in issue.). Hence, the prejudice to defendant resulting from joinder of the March 20 counts in the homicide indictment is lessened by the recognition that even if those counts were severed, the homicide jury would have been exposed to evidence recounting the events of March 20. See State v. Coruzzi, 189 N.J.Super. 273, 299 (App.Div.), certif. denied, 94 N.J. 531 (1983) (“[A] defendant will not suffer any more prejudice in a joint trial than he would in separate trials, because the evidence of the other alleged crimes would be admissible in any event under Evid.R. 55.”).

*603We also note that the potential for prejudice created by the joinder of counts in this case was lessened because defendant did not contest his commission of the homicides, focusing his defense on the contention that he was guilty of manslaughter rather than murder. In addition, the trial court, in its instruction, cautioned the jurors to deliberate separately on each of the twelve counts, and to return a judgment of conviction only if convinced that each element of the individual counts had been proved beyond a reasonable doubt. Although the instruction was adequate, it would have been preferable, particularly in a capital case and generally when multiple counts are joined in a single indictment, for the trial court to have emphasized to the jury its duty to avoid any negative or prejudicial impressions that might otherwise be created by the joinder of several criminal charges in a single indictment.

Based on our review of the record, we hold that the trial court’s denial of defendant’s motion to sever was not an abuse of discretion, and that defendant was not significantly prejudiced by the joinder of the March 20 counts with the homicide counts in the guilt phase of the proceedings. We observe, however, that the trial court did not instruct the jury in the penalty phase, as it was obliged to do, that the evidence relating to the non-homicide counts of the indictment were not to be considered as aggravating factors in the penalty-phase weighing process. State v. Moore, supra, 113 N.J. at 276-77; accord State v. Rose, supra, 112 N.J. at 505-06.

B. Should the Trial Court Have Charged the Jury on Aggravated Manslaughter?

1. Imperfect Self-Defense-Aggravated Manslaughter.

Defendant’s counsel acknowledged in his opening statement that defendant had killed Paul Reynolds and Stacey Elizardo, but asserted that the homicides had occurred in the heat of passion provoked by reasonable provocation. According to defense counsel’s review of the evidence in summation, the *604provocation consisted of Reynolds’ making insulting and mocking remarks to Pitts, Reynolds’ suggesting that Stacey was engaging in prostitution to earn money for drugs, an exchange of pushes and shoves, and, finally, Reynolds’ telling Pitts that he was going to his bedroom to get a gun. As requested, the trial court charged the jury on passion/provocation manslaughter as a lesser-included offense of murder. N.J.S.A. 2C:11-4b(2).

Defendant did not request a charge of aggravated manslaughter, but did request the trial court to instruct the jury on the doctrine of imperfect self-defense. The argument advanced was that defendant’s honest, but not necessarily reasonable, belief that Reynolds’ threat to get a gun endangered defendant’s safety constituted sufficient provocation to support a verdict of passion/provocation manslaughter. The trial court denied the requested instruction. Before this Court, defendant renews his contention that the trial court erred in refusing to instruct the jury on the doctrine of imperfect self-defense. Alternatively, defendant contends that our decision in State v. Bowens, 108 N.J. 622 (1987), filed after trial but before argument of defendant’s appeal, requires a trial court to charge aggravated manslaughter whenever evidence offered to prove imperfect self-defense is material to the state of mind required to prove murder.

In State v. Bowens, supra, we reviewed the sequence of events leading to adoption of the provisions of the Code of Criminal Justice (the Code) relating to self-defense. Id. at 629. We noted that the legislature expressly rejected a subjective test for self-defense, adopting instead a standard of objective reasonableness to determine when a decision to use force for self-protection was justifiable under the Code. Ibid.; see N.J. S.A. 2C:3-4(a). In Bowens, we also concluded that an honest but unreasonable belief in the need to use force for self-protection, insufficient under the Code to justify an otherwise unlawful homicide, could not of itself constitute a basis for mitigating *605homicide to an unspecified form of manslaughter. Id. at 630-31.

Nevertheless, we observed in Bowens that evidence of facts sufficient to establish “imperfect self-defense” may in certain cases “bear directly on the question of whether the homicide was knowing or purposeful, and would be admissible to counter these essential elements of the offense of murder.” Id. at 632. We noted examples of circumstances in which an unreasonable but honest belief in the need to use force could be pertinent to the elements of Code offenses:

An example given by the Attorney General of the multi-faceted nature of the defense includes the overreaction in self-defense to aggressive or threatening conduct, e.g., shooting to kill an unarmed attacker who has fallen to the ground. He noted that to the extent the victim’s conduct constitutes “reasonable provocation” the offense may be mitigated to become the Legislature’s special homicide offense, passion-provocation manslaughter. N.J.S.A. 2C:11-4(b)(2). Evidence of imperfect self-defense does not justify the conduct, it mitigates the offense. Another example given is the reckless use of mortal force in self-defense, as when one seeking to repel an attacker disregards a risk that pushing the aggressor down a cliff will result in death. That person may not have committed murder purposely or knowingly but may be guilty of one of the forms of manslaughter: either reckless homicide under N.J.S.A. 2C:11-4(b)(1) or reckless homicide manifesting extreme indifference to human life under N.J.S.A. 2C:ll-4(a). The evidence bears on the essential elements of a Code offense. [Id. at 633.]

Accordingly, we held in Bowens that although imperfect self-defense was not recognized by the Code as a justification for otherwise unlawful conduct,

in many cases the issues of the reasonableness of the defendant’s conduct presented to the jury in defense of the substantive crimes charged will have relevance to the essential elements of the homicidal act: whether it was the actor’s conscious object to inflict deadly force, whether death was almost certain to follow, or whether the act was done recklessly or with reasonable provocation. [Id. at 634.]

Defendant contends that our holding in Bowens compels the conclusion that the trial court committed reversible error in failing, sua sponte, to charge aggravated manslaughter on the basis of the evidence that defendant killed Reynolds because of an honest but unreasonable fear for his own safety. However, as we explained in Bowens, not every claim of *606imperfect self-defense leads to an aggravated manslaughter charge. The predicate for such an instruction, when it is based on evidence of imperfect self-defense, is that such evidence either negates the mental state required for murder, or demonstrates acts of provocation on the part of the victim to an extent sufficient to afford the jury a rational basis for convicting the defendant of one of the Code’s forms of manslaughter. N.J.S.A. 2C:ll-4a and 4b; see id. at 633. In this case, defendant testified that Reynolds “made a move to one of the bedrooms * * * to get this gun,” and it was “at that time * * * that I pulled the knife out from the back of me and assaulting [sic ] Paul with that knife.” Defendant described the assault as “almost an instantaneous like reflex,” committed in a “frenzied type state of mind.” We construe defendant’s testimony relating the Reynolds murder to Reynolds’ threat to “get this gun” as relevant to the crime of passion/provocation manslaughter, N.J.S.A. 2C:ll-4b(2), on which the trial court charged the jury. However, defendant’s version of the Reynolds’ homicide does not present facts that negate the state of mind indispensable for a conviction of murder, N.J.S.A. 2C:ll-3a(l) and (2), or afford the jury a rational basis on which to convict defendant of either aggravated or reckless manslaughter. N.J.S.A. 2C:ll-4a or 4b(l). No aspect of defendant’s testimony suggested that his state of mind was “reckless.”2 Accordingly, we find no error in the trial court’s failure to charge aggravated or reckless manslaughter on its own initiative based on defendant’s *607testimony offered to prove “imperfect self-defense” in connection with the Reynolds homicide.

2. Diminished Capacity — Aggravated Manslaughter.

Expert psychiatric testimony offered on defendant’s behalf included a diagnosis of defendant’s mental and emotional condition as well as an opinion concerning defendant’s state of mind at the time of the homicides. See supra at 591-592. Although defendant did not argue before us the defense of diminished capacity, N.J.S.A. 2C:4-2; see State v. Breakiron, supra, 108 N.J. 591, nor assert that the testimony of defendant’s psychiatric expert supported a charge of aggravated manslaughter, we requested supplemental briefs on these questions. In response to that request, defendant now contends that the testimony of Dr. Cooke concerning defendant’s cyclothymic personality disorder, supra at 591, combined with that expert’s opinion of defendant’s state of mind when he stabbed the victims, supra at 592, compelled the trial court, sua sponte, to instruct the jury on diminished capacity and aggravated manslaughter. The State disagrees sharply, arguing that defendant’s psychiatric expert did not establish any connection between defendant’s “personality disorder” and his state of mind when the homicides were committed. Moreover, the State asserts that throughout the trial defendant conceded that he killed the victims “knowingly,” infra at 612-613, but based his entire defense on the theory that the homicides occurred in the heat of passion, induced by reasonable provocation. Finally, the State contends that since defendant did not request instructions on either diminished capacity or aggravated manslaughter, the trial court had no duty “meticulously [to] sift through the entire record” to determine if some combination of facts and inferences might support such jury charges. See State v. Choice, 98 N.J. 295, 299 (1985).

In State v. Breakiron, supra, 108 N.J. 591, we considered the diminished capacity defense and concluded that

*608[it] was designed by the Legislature not as a justification or an excuse, nor as a matter of diminished or partial responsibility, but as a factor bearing on the presence or absence of an essential element of the crime as designated by the Code. The Legislature contemplated that all are not bom with equal mental capacity, and it would want a jury to consider whether a mentally defective person would be as practically certain as would another that death would result from the infliction of a serious blow. [Id. at 608.]

We also observed that

the mere presence of mental disease or defect does not perforce reduce murder to an unspecified degree of manslaughter. For the purpose of determining criminal guilt, diminished capacity either negates the state of mind required for a particular offense, if successful, or it does not. [Id. at 609.]

Although the discussion in Breakiron does not amplify the meaning of the phrase “mental disease or defect,” as it is used in N.J.S.A. 2C:4-2, we adverted to the difficulties inherent in attempting to correlate mental diseases with the categories of criminal culpability contained in the Code:

Not every mental disease or defect has relevance to the mental states prescribed by the Code. The variety and forms of mental disease are legion. They range from paranoia and schizophrenia to affective disorders and psychopathy. Some, such as depression or anti-social disorders, have little or no relevance to knowledge. Others, such as schizophrenia, are clearly relevant. Some states have attempted to define the relevant mental diseases or defects. Our Code does not. But “[b]oth jurists and mental health professionals recognize that there is no perfect correlation between legal standards of ‘insanity’ and psychiatric classifications of mental disorder.” [108 N.J. 618-19 n. 10 (citations omitted).]

Defendant’s psychiatric expert Dr. Cooke diagnosed defendant as having a “cyclothymic personality disorder,” a condition classified as a mental disorder by the American Psychiatric Association. APA, DSM III-R: Diagnostic and Statistical Manual of Psychiatric Disorders (DSM III-R) 226-28 (3d ed. Rev.1987). Dr. Cooke described the condition as a mood disorder that at times causes significant depression, but does not cause one to lose “contact with reality the way a manic depressant might.” In addition, Dr. Cooke testified that defendant had a “chronic anxiety disorder, and above-average level of anxiety on a chronic basis,” a condition also recognized by the American Psychiatric Association, DSM III-R at 251, and char*609acterized by unrealistic or excessive anxiety manifested by tension and hyperactivity. Ibid.

After testifying to his diagnosis of defendant’s mental condition, Dr. Cooke was asked his opinion of defendant’s state of mind at the time of the homicides. He explained that that opinion was based on diagnostic tests of defendant, physical evidence at the crime scene, and defendant’s statements to him. Although quoted above, supra at 592, the relevance of Dr. Cooke’s opinion to the issues under consideration warrants its restatement:

[U]nder that situation he experienced some of that feeling from Vietnam, not a specific flashback, but a feeling in which he perceives himself to be in danger, perceives himself as having to strike out to protect himself in part.
But even more important, that he had an emotional response there, an impulsive emotional response, not a response where he stopped and thought and decided, “I will do this, I will do that,” but, rather, a loss of control under the influence of extreme emotions and what I would say, combining all that data, a rage reaction, a reaction in which his anger reached the point of rage, which I would define as an anger that goes out of control and an anger which interferes with the cognitive ability a person has, planning, judgment, recognizing consequences, deliberating, that in my opinion, he experiences such a loss of control.

Dr. Cooke did not expressly connect his opinion of defendant’s state of mind to his diagnosis of defendant’s mental condition, but observed that his “testing” revealed defendant’s potential for “loss of control.”

On this record, we cannot conclude that it was plain error for the trial court to have failed to instruct the jury, sua sponte, on diminished capacity and aggravated manslaughter on the hypothesis that defendant’s mental condition was the cause of the loss of cognitive ability described in Dr. Cooke’s testimony. As Justice O’Hern noted in Breakiron, supra: “Not every mental disease or defect has relevance to the mental states prescribed by the Code.” 108 N.J. at 618 n. 10. We also observed in Breakiron that the only evidence of mental disease that should be admitted in respect of diminished capacity “is that relevant to the question of whether defendant had the requisite mental state to commit the crime.” Id. at 618. Dr. Cooke did not testify that defendant’s state of mind when *610he stabbed the victims was caused by his mental disorders; rather, he based his opinion on what defendant had told him about the homicides and on the physical evidence, as well as on his testing of defendant. Nor did Dr. Cooke testify that defendant’s particular mental disorders were generally acknowledged among psychiatrists to be capable of affecting one’s ability to possess the state of mind required by the Code for murder. Rather, the thrust of Dr. Cooke’s testimony was that defendant committed the homicides in a state of rage, provoked by his emotional reaction to the encounter with Reynolds. Inasmuch as defense counsel did not request a diminished capacity charge, and the evidence offered did not significantly relate defendant’s mental disorder to the state of mind described by defendant’s psychiatric expert, we hold that it was not plain error for the trial court to have failed, sua sponte, to instruct the jury on diminished capacity and aggravated manslaughter on the theory that defendant’s mental condition afforded the jury a rational basis for convicting defendant of the lesser charge. See State v. Choice, supra, 98 N.J. at 299; cf. State v. Juinta, 224 N.J.Super. 711 (App.Div.1988) (plain error for trial court to fail to charge diminished capacity in murder prosecution where principal issue at trial concerned insanity defense).

3. Aggravated Manslaughter — State-of-Mind Testimony.

Although not raised by counsel at trial or before us, the testimony of defendant’s expert concerning defendant’s state of mind when he stabbed the victims warrants our consideration of the appropriateness of an aggravated manslaughter charge based solely on the expert’s state-of-mind testimony. We address this issue independently of defendant’s contentions concerning imperfect self-defense and diminished capacity. “[WJhere the death penalty is involved, it is the duty of this Court to examine the record for any errors affecting the substantial rights of the accused, even though not made a ground of appeal.” State v. Gerald, 113 N.J. 40, 69 (1988) *611(quoting State v. Taylor, 213 S.C. 330, 330, 49 S.E.2d 289, 289 (1948)).

We focus particularly on Dr. Cooke’s statement that defendant experienced “a loss of control under the influence of extreme emotions * '* * a rage reaction, * * * which I would define as an anger that goes out of control and * * * which interferes with the cognitive ability a person has, planning, judgment, recognizing consequences, deliberating * * Unquestionably, this testimony by Dr. Cooke provided support for the court’s instruction to the jury, specifically requested by defense counsel, on passion/provocation manslaughter. As we noted in State v. Bonano, 59 N.J. 515 (1971):

Voluntary manslaughter * * * is an intentional homicide done in sudden passion or heat of blood, without malice aforethought. [Id. at 523.]

In State v. Guido, 40 N.J. 191 (1963), we described passion/provocation manslaughter as follows:

Voluntary manslaughter is a slaying committed in a transport of passion or heat of blood induced by an adequate provocation, provided the killing occurs before the passage of time sufficient for an ordinary person in like circumstances to cool off. The common law deemed such circumstances to negate the malice required for murder. Involved is a concession to the frailty of man, a recognition that the average person can understandably react violently to a sufficient wrong and hence some lesser punishment is appropriate. [Id. at 209-10 (citations omitted).]

Thus, our cases recognize that evidence sufficient to support a finding that a homicide was committed by one in a state of rage, induced by reasonable provocation, ordinarily would warrant a charge of passion/provocation manslaughter. See State v. Powell, 84 N.J. 305, 319-24 (1980); State v. Bishop, 225 N.J.Super. 596, 605 (App.Div.1988); State v. Washington, 223 N.J.Super. 367, 377 (App.Div.), certif. denied, 111 N.J. 612 (1988).

Although Dr. Cooke testified that defendant’s “anger” interfered with his cognitive ability, the expert did not conclude that defendant lacked the state of mind required for purposeful or knowing murder. Under the Code, conduct is “purposeful,” with respect to a result, if it is the person’s “conscious object” *612to cause such a result, N.J.S.A. 2C:2-2b(l); conduct is “knowing” if the person is “aware that it is practically certain that his conduct will cause such a result.” N.J.S.A. 2C:2-2b(2). The testimony that defendant’s anger “interfered with [his] cognitive ability [for] planning, judgment, recognizing consequences” was consistent with the concept that the passion sufficient to sustain a passion/provocation manslaughter verdict must disturb a defendant's reason:

[T]o reduce the crime from murder to manslaughter it must appear that the killing occurred during the heat of a passion resulting from a reasonable provocation, a passion which effectively deprived the killer of the mastery of his understanding, a passion which was acted upon before a time sufficient to permit reason to resume its sway had passed. [State v. King, 37 N.J. 285, 300 (1962).]3

Thus the expert’s testimony supported a passion/provocation manslaughter theory, but did not describe defendant’s state of mind in a manner inconsistent with responsibility for knowing murder. Defense counsel conceded as much in his colloquy with the trial court concerning his request for a charge on imperfect self-defense:

THE COURT: In terms of the manner in which the case has been tried to this jury we don’t have self-defense, we have at best manslaughter, heat of passion, reasonable provocation; if I perceive your defense, that is the way the case has been tried to the jury.
*613MR. GOLDSTEIN: That is absolutely correct.
THE COURT: And the knowing aspect of the killing you admit in your opening statement and the defendant testified to it and that is not in issue really:
MR. GOLDSTEIN: That is not in issue that he killed — that when he was doing what he was doing he was doing it knowingly. That is not in issue. But he was doing it knowingly because he may have in the words of Dr. Cooke “temporarily misperceived the situation as one in which he had to defend himself and act impulsively and emotionally at the time.” That is what Dr. Cooke said.
I don’t think that means he didn’t do it knowingly. In fact, if he has the honest belief that in the need to use deadly force to defend himself, that would be consistent with knowingly because he makes that decision at that time that he must use deadly force to defend himself. What I am saying is that decision is unreasonable under all the facts and circumstances, but it should constitute what was known under 2A as the imperfect self-defense * * *.

Moreover, Dr. Cooke offered no testimony suggesting that defendant’s state of mind when he stabbed the victims was reckless rather than purposeful or knowing. See N.J.S.A. 2C:2-2b(3) (“A person acts recklessly with respect to a material element of an offense when he consciously disregards a substantial and unjustifiable risk that the material element exists or will result from his conduct.”). Thus, we do not find in Dr. Cooke’s expert testimony a rational basis on which the jury could have convicted defendant of any other lesser-included offense of murder, except for passion/provocation manslaughter. See State v. Crisantos (Amagas), 102 N.J. 265, 276 (1986). Hence, we conclude, based on our review of Dr. Cooke’s opinion testimony concerning defendant’s state of mind at the time of the homicides, that the trial court properly charged the jury on passion/provocation manslaughter and did not err in omitting to instruct the jury on any other lesser-included offense of murder.

To recapitulate, we hold that it was not plain error for the trial court to have omitted to charge the jury on aggravated manslaughter — whether in connection with the proofs offered by defendant bearing on imperfect self-defense, diminished capacity, or state of mind. Examined in the context of the entire trial, defendant’s proofs attempted to persuade the jury *614that the homicides, although committed deliberately, were the product of impassioned impulse, provoked by circumstances that caused defendant to lose control of his emotions. The thrust of defendant’s proofs was that his actions were uncontrollable, not that his conduct was reckless in the sense of consciously disregarding a known risk. We are satisfied that the jury, charged on passion/provocation manslaughter, was thereby afforded the opportunity to consider that alternate verdict to murder to which defendant’s proofs were essentially directed. Thus, although we hold that defendant was not entitled to a charge on aggravated manslaughter, we are also satisfied that its submission to the jury would have had no effect on the verdict.

C. Effect of State v. Gerald.

Subsequent to the trial and argument of the appeal in this case, we held in State v. Gerald, 113 N.J. 40 (1988), that a defendant

who is convicted of purposely or knowingly causing 'serious bodily injury resulting in death’ under N.J.S.A. 2C:ll-3(a)(l) and (2), or either of them — as opposed to one who is convicted of purposely or knowingly causing death under those same provisions — may not he subjected to the death penalty. [Id. at 69.]

The jury in Gerald was instructed, consistent with the literal language of the Capital Punishment Act, N.J.S.A. 2C:ll-3a(l) and (2), that a conviction for capital murder could be sustained if it found either that the defendant purposely or knowingly caused death, or that the defendant purposely or knowingly caused serious bodily injury resulting in death. Because we concluded that the evidence in the record was susceptible to either finding, we reversed defendant’s capital murder conviction and remanded the matter for a new trial. Id. at 91-92. In our opinion in Gerald we acknowledged, although in a somewhat different context, that the evidence in some capital murder cases was so compelling that there could be “no question that [the defendant] intended the death of his victim.” Id. at 79-80 (citing State v. Ramseur, supra, 106 N.J. 123, and State v. Biegenwald, supra, 106 N.J. 13).

*615The trial court in this case, without having the benefit of our holding in Gerald, charged the jury in accordance with the statute. Its instruction did not require the jury to determine specifically, as required by Gerald, whether defendant purposely or knowingly caused the death of the victims, or whether defendant purposely or knowingly caused serious bodily injury that resulted in death. The trial court’s omission to charge the jury as contemplated by Gerald is of no material significance with respect to defendant’s conviction for the murder of Paul Reynolds because the jury did not impose the death penalty. Thus, defendant was exposed to the same sentence that could have been imposed were he to have been convicted of non-capital murder. See State v. Gerald, supra, 113 N.J. at 91.

However, because defendant was sentenced to death for the murder of Stacey Elizardo, we must determine whether the trial court’s omission of the Gerald charge requires reversal of defendant’s murder conviction. We are satisfied that on this record the evidence was minimally adequate to meet the “rational basis” standard established in State v. Crisantos (Arriagas), 102 N.J. 265, 278 (1986), which we characterized as imposing a low threshold for a lesser-included-offense charge. Defendant’s testimony that Stacey “was just an image at that time” and that “he didn’t have the intentional thought to harm these people” would have warranted the trial court in charging the jury on non-capital murder if Gerald had been decided before the trial of this case. Because we conclude that the Gerald charge would have been appropriate, we consider whether its omission was clearly capable of affecting the verdict. Hence, we evaluate the evidence in the record to ascertain whether the jury’s verdict effectively constituted a determination that defendant purposely or knowingly caused the victim’s death. Cf. State v. Zola, 112 N.J. 384, 406-07 (1988) (Although trial court’s positioning of diminished-capacity instruction had potential for confusing jury about availability of manslaughter verdicts independent of finding of diminished capacity, jury *616knew manslaughter was available verdict but concluded that proper verdict was murder.).

Because the Gerald issue was not raised by the parties, we requested supplemental briefs after argument concerning Gerald 's effect on defendant’s conviction for the Elizardo murder. Defendant argues that our holding in Gerald mandates reversal of his conviction for the murder of Elizardo, contending that it was possible for the jury to have determined that he intended only to cause her serious bodily injury and not death. Defendant relies primarily on his own testimony at trial, and that of Dr. Cooke, as a basis for a jury determination that he did not intend to kill Elizardo. On direct examination defendant stated:

At the time it was a moment that through the month I went past, I can recall now the circumstances. The actual assault was like almost an instantaneous like reflex for me to have assaulted him. I assaulted Paul with the knife; while I was doing so, from back of me was, it was like a frenzied-type state of mind, whereas, that now which I know Stacey was behind me, it was just an image at that time that I wheeled around and I sliced Stacey with the knife at the time.

The following exchange occurred during defendant’s cross-examination:

Q. And you believe it’s the macho thing to tell this jury that you killed her because she was prostituting herself and that Reynolds was pimping her, is that what you want this jury to believe?
A. I want the jury to believe that I didn’t have the intentional thought to harm these people.
Q. My question, sir, do you really want this jury to believe, not only that you killed her, but you killed her because Paul Reynolds was pimping her as a prostitute, is that what you want this jury to believe?
A. I don’t want them to believe anything like that about Stacey.

Dr. Cooke testified that defendant told him he was initially unaware that he was assaulting Stacey Elizardo:

He [defendant, Pitts] also then tells me that out of the corner of his eye he saw what at some times [sic] he described as an image, as a person, didn’t know who it was, he says, didn’t know if it was a male or female, but had a feeling very much like the feeling that he had when he was in Vietnam, I have to win, I have to survive, I am under attack, things of that nature.
I went into this with him in great detail; this is not a flashback into any specific incident, that is not like he is reliving a specific incident in Vietnam. I am not saying that. What I am saying, he had the general feeling under this stressful situation that he had had at times in Vietnam in just having to win, *617having to survive, having to strike out until there was no more motion around him. He said that he only afterwards realized that that was Stacey.

Defendant also relies on Dr. Cooke’s “state of mind” testimony in which he expressed the opinion that defendant killed Reynolds and Elizardo in the heat of a rage reaction, which he described as

an anger that goes out of control and an anger which interferes with the cognitive ability a person has, planning, judgment, recognizing consequences, deliberating, that in my opinion, he experiences such a loss of control.

The State concedes that the trial court did not charge the jury as required by Gerald, but contends that the evidence leaves “no doubt” that defendant purposely or knowingly killed Stacey Elizardo. The State relies in part on defense counsel’s opening statement to the jury:

Now, I am going to tell you that the evidence will indeed show that on March 22nd, 1984 Darryl Pitts did stab Paul Reynolds and Stacy Elizardo to death. It is not in this trial so much a question of what happened on that day as it is in fact a question of why it happened.
********
[Ijt’s our position that the evidence will show that Darryl was a sane, capable man who was provoked into a rage which literally compelled him to take part in this Vietnam style killing.

The State also refers to defendant’s threat to kill Elizardo on March 20, 1984, and to defendant’s concession on cross-examination that “you use a combat knife when you want to kill somebody.”

The State relies primarily on the testimony of the medical examiner to demonstrate that the wounds defendant inflicted on Elizardo were so numerous and penetrating that it would be “inconceivable” and “irrational” for the jury to have found that defendant meant to cause serious bodily injury but not death. The State notes that Elizardo’s throat was cut twice, and that “defendant drove the knife so deep into her chest three different times that it penetrated the chest and severed the vital aorta artery, esophogus [sic], and lungs, and fractured her third rib.” The State refers to several stab wounds that penetrated through the skull and into the brain. The State also relies on an *618autopsy report that revealed twenty-five to thirty separate stab wounds, the deepest of which penetrated six inches into the victim’s body.

The State observes that after the homicides defendant took the pulse of both victims and determined that they were dead. Moreover, according to James Gibbs who was waiting in the ear when defendant returned, he told Gibbs “I cut her throat, you don’t have to worry about her.” Gibbs stated that Pitts explained that the victims owed him money and said “[s]ee what I mean about paybacks is a bitch.”

The State also contends that the evidence of intent to kill is

at least as powerful, if not more powerful, in this case than it was in Ramseur. The manner of killings here — multiple stabbings — is similar to that in Ramseur as is the prior threats of death. However, here there is the peculiarly compelling evidence of intent to kill, as previously set forth, not present in Ramseur, which unquestionably reveals defendant’s conscious object to cause the death of Paul Reynolds and Stacy Elizardo. (Footnote omitted.)

It is evident that the proofs before the jury overwhelmingly established that defendant’s assault of Elizardo was so violent that death was inevitable. The medical examiner described the wounds as “deep, penetrating injuries.” Defendant does not dispute the severity of the wounds inflicted during his assault of Elizardo. Rather, defendant contends that on the basis of his testimony that he assaulted an “image,” in a “frenzied-type state of mind,” the jury could have concluded that his intent was to inflict serious bodily injury rather than death.

We first observe that the arguments advanced by defendant in respect of the Gerald issue were those submitted to the jury to support the contention that defendant was guilty only of passion/provocation manslaughter. The jury heard defendant testify that he assaulted an “image,” not knowing it was Stacey Elizardo. Defense counsel, in summation, told the jury that when Reynolds told defendant

Stacey has been sleeping with other men * * * to get money for drugs * * * this so enrages and so provokes Darryl that he falls into what Dr. Cooke called a raged reaction and he falls back on his training and his instincts from Vietnam and you have the fatal results that we have in this case.

*619The jury was instructed on passion/provocation manslaughter. Its verdict was a rejection of defendant’s contention that he killed in the heat of rage, or passion, brought on by reasonable provocation.

We also note that defendant’s testimony that he assaulted an “image,” not knowing it was Stacey Elizardo, was contradicted by defendant’s second statement to the police, which was read to the jury during the State’s case:

He was cut but it wasn’t severe enough but you can cut a human being and usually they’ll stay alive three minutes. That’s a known fact. According to you gentlemen, he was stabbed. All this is going on fast. This couldn’t have taken no more than ten, 15 seconds. When [Stacy] came out of the room, what the fuck you doing, jerkoff and on and on and on. I said because my fucking money is not in my hand and it went on. That’s when I, you know, attacked her. * * *
[After Reynolds had fallen against the wall, Stacy] went into hysterics. And when the hysterics went down, that’s when I fucked up
********
I guess originally it started as a struggle because 1 grabbed her and I tried to cut her throat. I told you before, you can use [the combat knife for] cutting someone’s throat. [Emphasis added.]

In addition, defendant’s direct testimony confirmed that he knew Elizardo was in the apartment because he saw her shoes and coat, and Reynolds said she was asleep. Supra at 590. Thus, the jury had ample basis in the record to reject defendant’s assertion that because of his “rage,” he was unaware until it was too late that Elizardo was the victim of his second assault.

But on the question that is decisive of the Gerald issue, whether the assault had as its objective serious bodily injury or death, the evidence consists almost entirely of testimony demonstrating either defendant’s purpose to kill or his knowledge that death was practically certain to occur. The medical examiner’s description of the wounds on Elizardo’s body incontrovertibly portrayed an assault that would take the victim’s life. In defendant’s second statement to the police he admitted that he attempted twice to cut Elizardo’s throat. Defendant’s pausing to take the pulse of the victims to verify their death and his *620incriminating statements to James Gibbs supplement the evidence demonstrating that defendant’s objective was death and not serious bodily injury.

If the jury in this case also had been charged in accordance with Gerald, it would have been required to determine whether defendant intended to kill Elizardo, or, alternatively, intended to cause her serious bodily injury. We concur with the State’s conclusion that on this record it would be virtually “inconceivable” that a jury could have concluded that defendant intended to cause serious bodily injury to Elizardo, but not death.

We expressed in State v. Bey, 112 N.J. 45 (1988), our belief that

in death penalty cases an appellate court must subject the record to intense scrutiny. The stark fact that a litigant’s life is at stake intensifies the obligation of judicial review. [Id. at 92-93.]

We also set forth in Bey the standard for assessing the effect of error in capital cases:

Thus, in assessing the impact of error in either the guilt or penalty phase of a capital case, we shall continue to determine reversibility on the basis of a qualitative determination that considers, in the context of the entire case, whether the error was clearly capable of affecting either the verdict or the sentence. * * * We are satisfied that its application in capital cases is sufficiently flexible to accommodate our heightened concerns and responsibilities in reviewing death-penalty prosecutions. [Id. at 94-95.]

After a meticulous review of the record in this case, we are convinced that the jury’s verdict was a determination that defendant purposely or knowingly caused the death of Stacey Elizardo. We are fully satisfied that the trial court’s omission of the charge required by Gerald was not capable of affecting the jury’s verdict. Moreover, we are convinced that “there was no realistic likelihood of prejudice” resulting from such omission, a standard of review proposed by our concurring colleague in Bey. 112 N.J. at 116 (Handler, J., concurring). No matter how indulgently this record is read, we cannot conceive that the jury, charged in accordance with Gerald, would have concluded that defendant intended to cause Elizardo serious bodily injury, but not death.

Guilt and Penalty Phase Issues

Admissibility of Psychiatric Expert Testimony Based on Sodium Amytal Interview of Defendant

During the guilt phase of the trial, defendant proffered the expert testimony of Dr. Robert Sadoff, a highly qualified forensic psychiatrist, concerning defendant’s state of mind at the time of the homicides. Defense counsel advised the trial court that Dr. Sadoff’s testimony was based in part on an interview while defendant was under the influence of an intravenously-administered barbiturate known as sodium amytal. The trial court conducted an extensive hearing pursuant to Evidence Rule 8 to determine the admissibility of the expert testimony. The Rule 8 hearing included testimony from Dr. Sadoff and two other highly qualified psychiatrists, Dr. Martin Orne for the State and Dr. Joseph DiGiacomo for the defendant. Following the hearing, the trial court ruled that Dr. Sadoff would not be permitted to give expert testimony in the guilt phase that was based on factual conclusions derived from defendant’s statements during the sodium-amytal interview. However, the court ruled that Dr. Sadoff’s opinion would be admissible if based on hypothetical facts consistent with evidence in the record. See Evid. R. 58.

During the penalty phase of the case, defense counsel again sought to elicit Dr. Sadoff’s expert testimony to support the existence of mitigating factors. The trial court ruled, as it did in the guilt phase, that Dr. Sadoff’s expert testimony was also inadmissible in the penalty phase if based on facts gleaned from defendant’s sodium-amytal interview. Although the trial court suggested that Dr. Sadoff could base his expert testimony in the penalty phase on facts already in evidence by virtue of defendant’s guilt phase testimony, defense counsel advised the trial court that Dr. Sadoff would not testify because of the limitations imposed by the trial court’s ruling. Defendant contends before us that the trial court’s rulings in both the *622guilt and penalty phases were erroneous, requiring reversal of defendant’s convictions for murder as well as reversal of his death sentence.

The general principles that determine the admissibility of scientific-type evidence were recently summarized in Romano v. Kimmelman, 96 N.J. 66 (1984):

In New Jersey, the results of scientific tests are admissible at a criminal trial only when they are shown to have “sufficient scientific basis to produce uniform and reasonably reliable results and will contribute materially to the ascertainment of the truth.” State v. Hurd, 86 N.J. 525, 536 (1981) (quoting State v. Cary, 49 N.J. 343, 352 (1967)). Scientific acceptability need not be predicated upon a unanimous belief or universal agreement in the total or absolute infallibility of the techniques, methodology or procedures that underlie the scientific evidence. * * * Reliability of such evidence must be demonstrated by showing that the scientific technique has gained general acceptance within the scientific community. State v. Johnson, 42 N.J. 146, 170-71 (1964). The fact that a possibility of error exists does not preclude a conclusion that a scientific device is reliable. This Court in Johnson noted: “Practically every new scientific discovery has its detractors and unbelievers, but neither unanimity of opinion nor universal infallibility is required for judicial acceptance of generally recognized matters.” Id. at 171 Once the showing of general acceptability has been made, courts will take judicial notice of the given instrument’s reliability and will admit in evidence the results of tests from the instrument without requiring further proof. [Id. at 80.]

Thus, in determining the admissibility of evidence derived from scientific procedures, a court must first ascertain the extent to which the reliability of such procedures has attained general acceptance within the relevant scientific community. See Windmere, Inc. v. International Ins. Co., 105 N.J. 373, 377-79 (1987). Testimony by qualified experts is an acknowledged method for proving general acceptance of a scientific procedure. Id. at 379-82.

The testimony at the Rule 8 hearing revealed substantial agreement among the three experts concerning the scientifically acceptable uses of testimony induced by sodium amytal. The witnesses agreed that sodium-amytal-induced interviews are not considered scientifically reliable for the purpose of ascertaining “truth.” See also State v. Sinnott, 24 N.J. 408, 421 (1957) (“The general consensus appears to be that while the ‘truth *623sera’ are valuable as a diagnostic aid because they tend to diminish the inhibitions of the subject being interviewed, they do not in any wise provoke a certainty of truth-telling on his part.”). See generally Dession, Freedman, Donnelly & Redlich, Drug-Induced, Revelation and Criminal Investigation, 62 Yale L.J. 315 (1953) (hereafter Dession, Drug-Induced Revelation ) (“Thus the bare results of an interview under the influence of drugs should not, standing alone, be considered a valid and reliable indicator of the facts.”). Id. at 342.

The experts also expressed general agreement that sodiumamytal-induced interviews, conducted by trained psychiatrists, may be useful diagnostically as a component of a comprehensive psychiatric evaluation. See, e.g., Dession, Drug-Induced Revelation, supra, 62 Yale L.J. at 342. However, the expert witnesses had somewhat different views concerning the use of an interview induced by sodium amytal to determine a suspect’s state of mind when committing a criminal act. Dr. Ome, the State’s expert, expressed significant reservations about the use of sodium amytal to determine state of mind. Although Dr. Orne agreed that sodium-amytal interviews could be useful diagnostically and therapeutically, he testified that the drug was not appropriate for use in a forensic setting to determine state of mind: “To “the extent that the state of mind on an historical event involves making judgments between two or three different statements that the patient has made and you don’t know which is true [sic]. You are using it as a truth-telling device and there is no use for that.” Dr. Orne expressed the opinion, based on Dr. Sadoff s reports and a videotape of the sodium-amytal interview, that Dr. Sadoff relied on the interview to ascertain which of the defendant’s versions of the homicides was truthful. Dr. Orne also noted that Dr. Sadoff’s questioning of defendant during the amytal interview was leading and suggestive.

Dr. DiGiacomo, defendant’s expert, testified that a sodiumamytal interview could be useful in assessing state of mind, and observed that a trained psychiatrist could use the interview *624diagnostically to determine if a suspect was psychotic or suffered from a traumatic neurosis. Dr. DiGiacomo testified that his review of the viodeotaped interview caused him to believe that defendant was not “totally in control” when he killed Stacey, and also helped him to rule out psychosis or neurosis as a reason for the homicides. During questioning by the court, Dr. DiGiacomo conceded that he found “troublesome” that portion of Dr. Sadoff’s report suggesting reliance on the amytal interview to determine the “veracity and reliability” of defendant’s statements.

Dr. Sadoff testified that he had interviewed defendant twice before conducting the interrogation with sodium amytal, the first time to determine competency to stand trial and the second time at the specific request of defendant’s trial counsel. He explained that the significant differences between defendant’s versions of the homicides on these two occasions, as well as defendant's accounts of his Vietnam combat experiences, prompted him to recommend an interview using sodium amytal. Dr. Sadoff testified that defendant’s responses to leading questions about Vietnam during the amytal-induced interview persuaded him that defendant had not experienced a “Vietnam flashback” when he committed the homicides and enabled him to rule out post-Vietnam stress syndrome as an explanation for defendant’s actions. Dr. Sadoff further testified to his conclusion, based on the amytal interview, that at the time of the homicides Pitts believed that Eeynolds was causing Elizardo to engage in prostitution, and, enraged by that belief, defendant killed both Eeynolds and Elizardo. Dr. Sadoff acknowledged that he had no opinion about whether Eeynolds actually had enticed Elizardo into prostitution, but concluded, based on Pitts’s statements while under the influence of sodium amytal, that Pitts’s belief that that had occurred was truthful and caused him to commit the homicides. During questioning by the trial court, Dr. Sadoff acknowledged that he derived from the sodium-amytal interview the opinion that Pitts killed the victims in a state of rage because of Pitts’s belief that Eeynolds *625was “pimping” Stacey, but denied that he had used the amytal interview to ascertain the truth of any facts other than what Pitts believed at the time of the homicides. Dr. Sadoff also acknowledged, during questioning by the trial court, that he could render an opinion on defendant’s state of mind without reliance on the amytal interview if the critical facts concerning defendant’s belief were included in a hypothetical question propounded by counsel.

At the conclusion of the Rule 8 hearing, the trial court held that Dr. Sadoff would not be permitted to rely on the sodiumamytal interview in expressing an opinion about defendant’s state of mind when he killed Paul Reynolds and Stacey Elizardo. The court concluded that Dr. Sadoff had “relied on sodium amytal to determine the truth or veracity of what the defendant believed.”4 Acknowledging agreement among the three expert *626witnesses that sodium-amytal interviews are not scientifically reliable for ascertaining truth, the trial court concluded that Dr. *627Sadoff’s proposed use of the amytal interview was unreliable and therefore impermissible. The court specifically noted, however, that Dr. Sadoff would be permitted to render his expert opinion about defendant’s state of mind if based on a hypothetical question consistent with the evidence in the case. Nevertheless, defendant’s counsel made no further attempt to elicit Dr. Sadoff’s testimony during the guilt phase of the case.

In the guilt phase the trial court did not specifically decide the question whether defendant’s expert could use the sodiumamytal interview diagnostically, as a basis for an expert opinion concerning defendant’s state of mind at the time of the homicides:

The distinction from this case is that there is an attempt on Dr. Sadoff’s part to use it as a so-called diagnostic tool of some sort and on the basis of that to give an opinion to the jury concerning the state of mind of the defendant at the time these offenses were committed. So that raises a sub-issue as to whether or not the test is reliable enough to a psychiatrist using it to enable or allow him to give an opinion to a jury which is based upon the employment of that test. And I think this case doesn’t even require this Court to make that determination in any broad or general terms, because the very limited question involved here is the use of the test by Dr. Sadoff and whether he used it to ascertain truth or whether he used it as some sort of a diagnostic tool having no relationship to truth or falsity, because it does appear in those situations where it is allowed, it is allowed because the expert psychiatrist who employs it does not employ it to determine the truth and his opinion as a result of its use is not based upon the truth or falsity of what was ascertained because it makes no difference to the opinion given.
In this case, my very strong impression is Dr. Sadoff used it * * * for the purpose of ascertaining the belief of the defendant which is a fact and based upon that fact he has formulated his opinion, which is to say that he has relied on sodium amytal to decide the truth or veracity of what the defendant believed.

However, the clear implication of the trial court’s ruling was that a sodium-amytal interview could be used diagnostically as a basis for an expert’s opinion, as our dissenting colleague suggests, post at 666, provided the content of the interview is not offered to prove the truth of the declarant’s statements.5

*628As noted above, supra at 621, at the conclusion of the penalty phase defense counsel again sought to elicit Dr. Sadoff s expert testimony on defendant’s state of mind to support the mitigating factor set forth in N.J.S.A. 2C:ll-3c(5)(a): “The defendant was under the influence of extreme mental or emotional disturbance insufficient to constitute a defense to prosecution.” The trial court ruled, as it did in the guilt phase, that Dr. Sadoff could not rely on the sodium-amytal interview to express an opinion about defendant’s state of mind based on defendant’s beliefs at the time of the homicides. The court observed, however, that defendant had testified in the guilt phase about the very same “beliefs” that Dr. Sadoff learned of during the amytal interview. Hence, the court emphasized that Dr. Sadoff could testify about defendant’s state of mind in the penalty phase on the basis of defendant’s direct testimony, but could not base his opinion on the truthfulness of statements made by defendant during the sodium-amytal interview. The trial court was asked specifically by defense counsel if his ruling precluded defendant’s expert from offering any state-of-mind opinion based on the sodium-amytal interview. In response, the trial court acknowledged the diagnostic value of sodium-amytal interviews but declined to rule “in a vacuum” on *629the admissibility of such testimony.6 Defense counsel did not call Dr. Sadoff to testify in the penalty phase of the case.

We are fully in accord with the trial court’s holding that precluded Dr. Sadoff from using the sodium-amytal-induced interview of defendant to provide expert opinion testimony on defendant’s state of mind in the guilt phase of the trial. We find the trial court’s assessment of Dr. Sadoff’s Rule 8 testimony to be perceptive and accurate. Although Dr. Sadoff may have used defendant’s amytal interview diagnostically to some extent, it is uncontrovertible that he relied on the inter*630view to ascertain the truth of defendant’s beliefs about the reasons he had committed the homicides. Thus, state-of-mind testimony by Dr. Sadoff, based on defendant’s “beliefs” expressed during the amytal interview, would have exposed the jury to an expert opinion derived at least in part from a scientific procedure that has not attained general acceptance in the scientific community.

On the two occasions that this Court has considered the question, we have concluded, based on the then-existing state of scientific knowledge, that testimony derived from a sodiumamytal-induced interview is inadmissible to prove the truth of the facts asserted. See State v. Levitt, 36 N.J. 266, 275 (1961); State v. Sinnott, supra, 24 N.J. at 421-23. Our rule is consistent with the views expressed by other courts that have addressed the issue. See United States v. Solomon, 753 F.2d 1522, 1525-26 (9th Cir.1985); United States v. Swanson, 572 F.2d 523, 527-28 (5th Cir.), cert. denied, 439 U.S. 849, 99 S.Ct. 152, 58 L.Ed.2d 152 (1978); Chapa v. Chapa, 491 So.2d 969, 970-71 (Ala.Civ.App.1986); State v. Thomas, 79 Ariz. 158, 285 P.2d 612, 613-14 (Sup.Ct.1955), cert. denied, 350 U.S. 950, 76 S.Ct. 326, 100 L.Ed. 828 (1956); Fetters v. State, 436 A.2d 796, 800 (Sup.Ct.Del.1981); Harper v. State, 249 Ga. 519, 292 S.E.2d 389, 395-96 (Sup.Ct.Ga.1982); State v. Linn, 93 Idaho 430, 462 P.2d 729, 732 (Sup.Ct.1969); State v. Rosencrantz, 110 Idaho 124, 714 P.2d 93, 99 (Idaho App.1986); State v. Foerstel, 674 S.W.2d 583, 593-94 (Mo.App.1984); State v. Delk, 692 S.W.2d 431, 439 (Tenn.Cr.App.1985); Cain v. State, 549 S.W.2d 707, 711-12 (Texas Cr.App.), cert. denied, 434 U.S. 845, 98 S.Ct. 149, 54 L.Ed.2d 111 (1977). The expert testimony adduced at the Rule 8 hearing indicated that the scientific community continues to view testimony induced by sodium amytal as unreliable to ascertain truth. Thus, the trial court’s ruling excluding Dr. Sadoff’s testimony in the guilt phase was consistent with our precedents, with the weight of authority throughout the country, and also with contemporary scientific knowledge as reflected by the expert testimony. Moreover, the trial court *631properly acknowledged that Dr. Sadoff could furnish expert testimony based on a hypothetical question, supported by other evidence in the record, that set forth the facts revealed to Dr. Sadoff during the sodium-amytal interview. We find no error in the trial court’s disposition of this issue.

Nor do we find error in the trial court’s ruling that precluded Dr. Sadoff from furnishing expert testimony in the penalty phase that relied on factual conclusions derived from the sodium-amytal interview. In this connection, we first observe that the jury determined that the mitigating factor to which Dr. Sadoff’s testimony was directed, N.J.S.A. 2C:11-3c(5)(a),7 existed with respect to both homicides. We acknowledge, of course, that the weight the jury ascribed to that mitigating factor may have been affected by the exclusion of Dr. Sadoff’s testimony.

Defendant contends that the trial court’s ruling concerning Dr. Sadoff’s testimony in the penalty phase was error. Defendant relies on State v. Davis, 96 N.J. 611 (1984), and State v. Timmons, 192 N.J.Super. 141 (Law Div.1983), in support of his assertion that a much less stringent standard should be applied to evidence proffered by a defendant in the penalty phase of a capital case than that which governs admissibility during the guilt phase.

We note that since the trial of this case the legislature has dealt with the essence of defendant’s contention, although not its specific application in this case, by amending the Capital Punishment Act to prescribe a more tolerant standard of admissibility for evidence offered by a defendant to support one or more mitigating factors. N.J.S.A. 2C:ll-3(c)(2)(b) now provides:

*632(b) The admissibility of evidence offered by the State to establish any of the aggravating factors shall be governed by the rules governing the admission of evidence at criminal trials. The defendant may offer, without regard to the rules governing the admission of evidence at criminal trials, reliable evidence relevant to any of the mitigating factors. If the defendant produces evidence in mitigation which would not be admissible under the rules governing the admission of evidence at criminal trials, the State may rebut that evidence without regard to the rules governing the admission of evidence at criminal trials. [¿.1985, c. 178 (approved and effective June 10, 1985).]

Although we need not literally apply the provisions of N.J. S.A. 2C:ll-3(c)(2)(b) to the issue before us,8 the thrust of that amendatory provision was foreshadowed by our holding in State v. Davis, supra, 96 N.J. 611. In that case defendant pled guilty to murder and sought to offer in the penalty phase of the proceeding expert testimony from a professor of sociology, based on statistical data, that a person sharing defendant’s statistical profile would be unlikely to commit further crimes if released from prison after serving the mandatory minimum thirty-year term. Although expressly declining to rule on the admissibility of the proposed testimony in respects other than relevancy, we held that the proffered expert testimony “generally satisfies broad standards of relevancy” and hence was admissible to establish a mitigating factor in the penalty phase. Id. at 621. In reaching that conclusion, we “ascribe[d] to the Legislature full appreciation of the singular nature of the penalty phase of a capital proceeding and the ineluctable conclusion that doubts must be resolved in favor of admission when evidence of a mitigating factor is offered by the defendant.” Id. at 620. We specifically noted that our determination *633was “consistent with Senate Bill 950, the proposed amendment to N.J.S.A. 2C:ll-3 * * Id. at 621 n. 1.

Our opinion in Davis also set forth broad guidelines for determining the admissibility of evidence to establish mitigating factors in the penalty phase of a capital case:

We stress, however, that the conventional standards of competency, relating to both the expert’s qualifications and the scientific reliability of the subject matter, are not to be strictly applied in this context — the penalty phase of a capital proceeding — in which the choice before the jury is between life and death.
We have recognized that standards of proof may vary depending upon the litigational context. Evidential rules or standards of admissibility in the sense of the authenticity or competency of evidence may likewise be varied depending upon the purpose to be served by the evidence. With respect to the sentencing of a convicted criminal, as noted, we have been extraordinarily tolerant as to the subject and form of evidence to be considered in this most delicate kind of determination. * * *
A lowered threshold of admissibility for evidence proffered in mitigation of the death penalty in the sentencing phase of a criminal proceeding is consistent with this recognition. In this setting, it would be incorrect for the court to apply the evidential prerequisites with the same strictness that is required in the guilt phase of the trial. When guilt is not the determinative issue, greater flexibility and latitude may be accorded a factfinder in his or her use of expert testimony.
To the extent that evidence of the type sought to be proffered in the case at bar arguably may suffer shortcomings when measured by strict rules of evidential relevance and competence, such deficits will go to the weight of the testimony, properly relegating to the adversarial process the task of “separating the wheat from the chaff.”
However, relaxed standards for admissibility are not to be equated with automatic admissibility. Judicial tolerance is not judicial license. For example, in this case the court may, upon a persuasive showing, consider the report, or any of its component parts, incomplete and therefore unhelpful. Arguably, the report could, upon countervailing proofs presented by the prosecutor through cross-examination or rebuttal evidence, be considered untrustworthy because of its failure to consider the educational background, employment history, familial status, criminal record, or some other important demographic factor relating to the potential for rehabilitation. It might also be considered flawed because of its use of, or its undifferentiated emphasis upon, statistical data based upon race, gender, or some other suspect characteristic. The court must retain discretion to exclude the evidence, in whole or in part, if it? probative value is substantially outweighed by its unfounded or speculative character and the risk of confusion of the essential issues. [Id. at 621-24 (citations and footnote omitted).]

*634Application of the principles enunciated in Davis does not produce a simplistic resolution of the issue before us. As noted above, supra at 585-586, defendant’s death sentence must be reversed on other grounds. Thus, the admissibility of Dr. Sadoff’s penalty phase testimony is not of critical consequence to our disposition of this appeal. Nevertheless, its resolution is desirable here since the issue may present itself again on remand and may also recur in other capital proceedings.

We consider two factors to be particularly decisive in our conclusion that the trial court properly excluded the proffered testimony of Dr. Sadoff. First, we read the record of the Rule 8 hearing as demonstrating a concession by Dr. Sadoff that he used the sodium-amytal interview to establish the truth of defendant’s belief about the reason he murdered the victims, a use that appears to conflict with the prevailing opinions in the scientific community concerning the reliable uses of sodiumamytal-induced testimony. Second, the trial court offered defense counsel the opportunity to elicit Dr. Sadoff’s expert opinion in the penalty phase on the basis of defendant’s direct testimony in the guilt phase that was virtually identical to the statements elicited by Dr. Sadoff from defendant during the sodium-amytal interview. Although we acknowledge that Dr. Sadoff’s opinion based on the defendant’s statements during the amytal interview, corroborated by defendant’s direct testimony, might have had a greater impact on the jury, we cannot criticize the trial court for balancing the potential impact of the proposed testimony against its apparent unreliability. We read the trial court’s ruling as acknowledging Dr. Sadoff’s right to testify to his expert opinion of defendant’s state of mind based in part on the sodium-amytal interview, relying on defendant’s trial testimony, rather than his statements during the amytal interview, to establish defendant’s belief about why he killed Reynolds and Elizardo. In our view, the trial court’s disposition of this issue was pragmatic, balanced, and thoroughly consistent with the relaxed standards of admissibility endorsed *635by our opinion in Davis. Hence, we find no error in the trial court’s ruling.

Had the state of the record not permitted the trial court to offer Dr. Sadoff the opportunity to testify based on defendant’s guilt-phase testimony, application of the principles set forth in Davis would have suggested that Dr. Sadoff be permitted to testify about his opinion based on defendant’s beliefs expressed in the amytal interview. In that event, the trial court would have been compelled to charge the jury concerning the unreliability of facts learned from a subject testifying under the influence of sodium amytal, and Dr. Sadoff’s opinion could have been challenged on cross-examination and by rebuttal testimony. Total exclusion of penalty-phase evidence to support a mitigating factor should occur only in those circumstances in which a trial court is convinced that its admission, taking into account the balancing effects of cross-examination, rebuttal testimony, and curative instructions, would frustrate rather than advance society’s interest in according a fair trial to a capital defendant.

Penalty Phase Issues

A. Aggravating Factor 2C:ll-3c(4)(c).

Since the trial of this case occurred before our decisions in State v. Ramseur, supra, 106 N.J. 123, and State v. Biegenwald, supra, 106 N.J. 13, the trial court, in charging the jury concerning aggravating factor c(4)(c),9 did not have the benefit *636of our narrowing construction of that aggravating factor. See State v. Ramseur, supra, 106 N.J. at 198-211. We noted in Ramseur that the introductory language of factor c(4)(c) (“[t]he murder was outrageously or wantonly vile, horrible or inhuman”), “is indefinite beyond anyone’s ability to remedy * * Id. at 199. Thus, we determined that in the application of this aggravating factor “the first part of the provision is rendered nugatory. The resultant construction is that the aggravating factor exists when the murder ‘involved torture, depravity of mind, or an aggravated battery to the victim.’ ” Ibid. We also adopted in Ramseur a narrowing construction of c(4)(c) in order to satisfy constitutional standards, and we concluded that the defendant’s state of mind was the critical element:

We are convinced that the essence of the legislative concern is the defendant’s state of mind. We do not believe that the legislature intended to distinguish between two murderers each of whom intended to inflict immediate death upon the victim without any additional suffering whatsoever, when one victim dies immediately and the other lives for a long period of time and experiences excruciating pain. That capricious event alone would be perceived as an insufficient basis on which to inflict death on that defendant while imposing imprisonment on the other. Our system of criminal laws is predicated usually on the imposition of punishment based on the defendant’s intent. Indeed, our Code’s ranking of crimes by degree places those crimes committed with intentional conduct as the highest degree of crime, for which the defendant is most severely punished. Society’s concern, the community’s concern, the Legislature’s concern, is to punish most harshly those who intend to inflict pain, harm, and suffering — in addition to intending death. [106 N.J. at 207-08.]

We also set forth in Ramseur the essential elements of a proper charge to a jury on factor c(4)(c):

Therefore, depending on the facts, the jury should be charged — without quoting the statute — that this aggravating factor exists if the murder involved torture, depravity of mind, or an aggravated battery to the victim. Torture or aggravated battery to the victim shall be found if the defendant intended to cause, and did in fact cause, severe physical or psychological pain or suffering to the victim prior to the victim’s death, “severity” measured either by the *637intensity of the pain, or the duration of the pain, or a combination of both. Where the murder was not the product of greed, envy, revenge, or another of those emotions ordinarily associated with murder, and served no purpose for the defendant beyond his pleasure of killing, the court shall instruct the jury on the meaning of depravity in this specific context. For the defendant who killed for the enjoyment of it, because the victim just happened to be in the area, or for no reason at all, just to kill, society must be able to reserve its most extreme sanction. [106 N.J. at 211 (footnotes omitted).]

Accordingly, defendant contends that the trial court’s c(4)(c) charge was error, and the State acknowledges, as indeed it must, that the charge did not conform to our holding in Ramseur. This constitutes an additional ground for reversal of defendant’s death sentence.

Although at oral argument defense counsel agreed with the State’s assertion that aggravating factor c(4)(c) could be submitted to the jury in the event, on remand, the State again sought to impose the death penalty, we would caution the trial court that on an issue of that magnitude counsel’s concession could not relieve the trial court of its responsibilities. Thus, if the issue is presented on remand, the trial court must independently assess the State’s proofs, in the context of our holding in Ramseur, in order to determine whether the State has adduced sufficient evidence that defendant intended to and did inflict severe physical or psychological pain on Elizardo before her death to support a jury finding that this factor exists.

B. Admissibility of Crime Scene and Autopsy Photographs in Penalty Phase.

During the guilt phase of the trial, three photographs were admitted in evidence without objection. The photographs depicted the interior of Reynolds’ apartment, the stairwell outside the apartment, and the location of the victims’ bodies. On defense counsel’s objection, the trial court excluded three other photographs of the victims under Evidence Rule 4, and also excluded on the same ground a series of autopsy photographs of the victims.

*638During the penalty phase of the case, the State sought again to introduce in evidence the crime scene and autopsy photographs that had been excluded in the guilt phase. Defense counsel objected, contending that the close-up color photographs of the bloodstained victims and the close-up autopsy photographs depicting the location of the stab wounds were highly inflammatory and so potentially prejudicial as to outweigh any relevance of the photographs to any issue in the penalty phase. The trial court, applying as noted above, supra at 635, a pre-Ramseur interpretation of aggravating factor c(4)(c), ruled the photographs to be admissible:

First with respect to the three already marked, S-ll, 12 and 16, and generally with respect to all of them, it seems to me where the burden of the State is to prove that the killing was outrageously or wantonly vile, horrible or inhuman, involving an aggravated battery to the victim or torture, that it would be foolhardy to say that the pictures which demonstrate graphically the extent of the wounds — especially with respect to the autopsy pictures demonstrate the extent of the wounds, the nature of the wounds and on what parts of the body they were inflicted, the pictures indicating the crime scene which again demonstrate, inferentially at least, the violence which must have been involved to give rise to that particular scene are all very relevant, highly probative in the penalty portion.
I have looked at them with a view to determining whether or not that probative value is overcome by any potential to invoke passion on the part of the jury or prejudice on the part of the jury as a result of that passion, and I don’t think they do.

As noted, the interpretation of factor c(4)(c) adopted in State v. Ramseur, supra, 106 N.J. 123, filed after the trial in this case, focuses on the defendant’s intention to inflict severe physical or psychological pain prior to death, supra at 635-637, an issue concerning which crime scene and autopsy photographs would have only limited, if any, relevance. Moreover, the extent to which the victims endured pain before death would be a subject more appropriately addressed by expert medical testimony than by photographs. Although as a general rule the admissibility of photographs of a crime victim rests in the trial court’s discretion, State v. Thompson, 59 N.J. 396, 420 (1971), the need to balance the ostensible relevance of such *639evidence against the likelihood of jury prejudice is especially critical in the penalty phase of a capital case. It is evident that the photographs were inadmissible in the penalty phase for the purposes stated by the trial court. In the event, on remand, some or all of these photographs are offered to support aggravating factor c(4)(c) as interpreted in Ramseur,10 the trial court should carefully evaluate their admissibility in the context of the State’s burden of proof, other evidence adduced by the State, and the provisions of Evidence Rule 4.

C. Weighing of Aggravating and Mitigating Factors.

As noted above, supra at 585-586, the trial court’s charge to the jury did not comply with our holding in State v. Biegenwald, supra, 106 N.J. at 67, that the jury must find that the aggravating factors outweigh the mitigating factors beyond a reasonable doubt in order for the trial court to impose the death sentence. Consistent with the statutory provisions then in effect, the trial court instructed the jury that unless each aggravating factor proved is outweighed by the mitigating factors, the sentence will be death. Similarly, the jury verdict sheet relating to the murder of Stacey Elizardo reflected the jury’s determination that the sole aggravating factor was not outweighed by the mitigating factors. The State concedes that the jury charge and the lack of a specific finding that the aggravating factor outweighs the mitigating factors beyond a reasonable doubt requires that the death sentence be vacated.

VI.

The judgments of conviction are affirmed. Defendant’s sentence to death for the murder of Stacey Elizardo is reversed and the matter is remanded to the Law Division for resentencing. Defendant’s sentence to life imprisonment with thirty-*640years parole ineligibility for the murder of Paul Reynolds is affirmed, as are the concurrent sentences for the remaining unmerged counts of the indictment.

The trial court merged count four, possession of a knife for an unlawful purpose (N.J.S.A. 2C:39-4(d)), with the two counts of murder. Count twelve, unlawful possession of a knife (N.J.S.A. 2C:39-5(d)) was merged with count eleven, and count ten, possession of a sawed-off shotgun (N.J.S.A. 2C:39~5(b)), was merged with count six.

N.J.S.A. 2C:2-2b(3) provides:

A person acts recklessly with respect to a material element of an offense when he consciously disregards a substantial and unjustifiable risk that the material element exists or will result from his conduct. The risk must be of such a nature and degree that, considering the nature and purpose of the actor’s conduct and the circumstances known to him, its disregard involves a gross deviation from the standard of conduct that a reasonable person would observe in the actor’s situation. "Recklessness," "with recklessness” or equivalent terms have the same meaning.

The Model Penal Code’s rationale for punishing passion/provocation manslaughter less severely than murder is somewhat different from that emphasized at common law:

A sudden rage, however engendered, does not necessarily or even probably negate an intent to kill. More likely it reinforces the firmness of the actor’s resolve to take the life of another. At most, therefore, provocation affects the quality of the actor’s state of mind as an indicator of moral blameworthiness. Provocation is thus properly regarded as a recognition by the law that inquiry into the reasons for the actor’s formulation of an intent to kill will sometimes reveal factors that should have significance in grading. It is a concession to human weakness and perhaps to non-deterability, a recognition of the fact that one who kills in response to certain provoking events should be regarded as demonstrating a significantly different character deficiency than one who kills in their absence. [American Law Institute, Part II, Model Penal Code and Commentaries § 210.3, comment 5 at 54-55 (1980).]

Our dissenting colleague argues that “[i]t is unfair and inaccurate to conclude, as did the trial court, that Dr. Sadoff was of the opinion that the defendant acted with the belief that Stacey was engaged in prostitution simply because the defendant said this during the sodium-amytal interview." Post at 665-666. However, at several stages of the Rule 8 hearing Dr. Sadoff appeared to acknowledge that it was only during the sodium-amytal interview that defendant expressed his belief that he killed Stacey Elizardo in a state of rage:

THE COURT: Well, let me share with you my dilemma. I have the impression that you, Dr. Orne, and Dr. DiGiacomo would all agree that as a fact-determining drug sodium amythal [sic] is totally ineffective.
THE WITNESS: I would agree.
THE COURT: And it would appear that this state of the law that as such, the results of such a test are inadmissible in the courts of law of this state.
THE WITNESS: Yes.
THE COURT: I have the further impression that there are many areas of diagnosis and/or treatment where it is a useful tool to a trained psychiatrist.
THE WITNESS: Yes.
THE COURT: I have listened to your testimony and I have the impression you are saying you have concluded that the defendant was in a state of rage when he committed the offenses?
THE WITNESS: Yes.
THE COURT: And that that rage was because of his belief that Stacy was being pimped by Paul Reynolds?
*626THE WITNESS: Yes.
THE COURT: Is that accurate?
THE WITNESS: Yes.
THE COURT: And the only place the fact of that pimping which is the basis for your opinion comes from are the sodium amythal [sic] testing * ** * so that anyone who puts it on any kind of scale, it seems to me, would say this was the least reliable part of a totally unreliable test, but the doctor has learned the facts as a result of it; how do I deal with that and resolve that in terms of it is not reliable to ascertain the truth? Have you used it to ascertain the truth of what was in his mind on that date?
THE WITNESS: Have I?
THE COURT: Pitts. Yes.
THE WITNESS: I have not, no.
THE COURT: You have not?
THE WITNESS: I have not. I would not allege in any way or fashion that the information about pimping or about Stacy being a prostitute has any factual basis at all. I don’t know if it’s the truth. What I believe is from my testing, that Darryl Pitts believed at least under sodium amytal that that was the reason he killed her.
THE COURT: And related to you under the least reliable part of the test?
THE WITNESS: All right. Yes.

Also, during cross-examination Dr. Sadoff indicates that his testimony about defendant’s rage was based on the sodium-amytal interview.

BY MR. KASSELMAN:
Q. Well, how does — well, before the test, Doctor, you indicated that you weren’t able to give an opinion in this case, isn’t that correct?
A. I said—
Q. You didn’t feel comfortable giving an opinion?
A. I didn’t feel that I could give one within a reasonable medical certainty.
Q. Right. Exactly.
A. An opinion about the Vietnam stress syndrome, and I had no other understanding as to why these two people were killed, and I said if we do the sodium amythal [sic] we can either confirm the Viet Nam stress syndrome idea or maybe something else will emerge. And what came out was this story that I had not had before which seemed to me to be consistent with the type of rage that would be necessary for homicide under those circumstances.
Q. So that based upon the sodium amytal test you received some information which led you to eliminate Vietnam and to substitute in its place another scenario for the killing, is that correct?
A. I guess that is a way to put it, yeah.

At the conclusion of the Rule 8 hearing the trial court observed:

*628That does not mean to say that the defense is foreclosed from getting Dr. Sadoffs opinion in evidence, and I believe that it would be very appropriate one, to give Dr. Sadoff the hypothetical state of facts, assuming it's based on evidence, and let him give his opinion based on those facts.
Now, in that case if the jury believes the facts they can evaluate his opinion and if they disbelieve the facts which are the basis of his opinion, then they are in position to give it what weight or credibility they believe it deserves.
On the other hand, if the defendant should decide to testify and decide to tell the jury and everyone else what the basis of his thinking was at the time, then of course, Dr. Sadoff would be at liberty to take that information in the form of underlying facts and give an opinion. The jury then is able to evaluate the underlying facts, as jurors are able to do, without being asked to evaluate a sodium amytal testing procedure which apparently even the experts can't agree on evaluating.

The colloquy on this point follows:

My ruling now is sodium amytal is unreliable as a truth ascertaining device. The psychiatric profession said it unanimously and the courts have said it unanimously, and it doesn’t make any difference whether it’s the penalty phase or guilt phase, it is still unreliable and it is its unreliability which makes it inadmissible.
Beyond that, I rule nothing. Dr. Sadoff may come in and say whatever he wants to, and if you want his opinion, it seems to me all you have to do is feed him the information that he got under the sodium amytal because now your client has testified to it in this Court and it would be a very proper basis for Dr. Sadoff’s opinion.
Have I left anything unclear?
MR. GOLDSTEIN: The only thing I am the least bit unclear about, and maybe, it’s been a long day, maybe I am being somewhat obtuse, but the only thing I am a little bit unclear about, are you indicating that Dr. Sadoff may not tell the jury on direct that he believes him under the sodium amytal because of the sodium amytal, but he may in fact tell the jury that he gave him a sodium amytal interview without expressing his opinion?
THE COURT: What probative value would that have?
MR. GOLDSTEIN: Well, the same thing when you say, "Did you give him the Minnesota Multiphasic'Personality Test?”
THE COURT: The Minnesota Multiphasic Personality is a well recognized and accepted psychiatric test.
MR. GOLDSTEIN: So then I am correct that Dr. Sadoff would not be allowed to mention the sodium amytal?
THE COURT: No, I am not saying that because I don’t know in what context he would want to say it. It does have some diagnostic aid to psychiatrists: we heard two days of what they are. I don’t know whether any of them are relevant in this case and I am not going to make rulings in a vacuum.

The mitigating factor set forth in N.J.S.A. 2C:ll-3c(5)(a) is as follows: “The defendant was under the influence of extreme mental or emotional disturbance insufficient to constitute a defense to prosecution."

The Senate Judiciary Committee's Statement to Senate Bill No. 950 (¿.1985, c. 178) includes the following explanatory comment: "In enacting the amendments contained in this bill, the intent of the Legislature is to effect only prospective changes. The amendments are not intended to apply retrospectively or to affect cases now on appeal.” But cf. State v. Biegenwald, supra, 106 N.J. 13, 65-67 (1987) (holding that provision in Chapter 178, Laws of 1985 requiring jury to find beyond a reasonable doubt that aggravating factors substantially outweigh mitigating factors would be applied retroactively to defendant based on fundamental fairness).

The trial court’s charge to the jury on aggravating factor c(4)(c) was as follows:

Insofar as the first aggravating factor which I have just mentioned in connection with each of the murders, although every murder may be viewed as vile, horrible or inhuman, this does not mean that there is an automatic aggravating factor in every case of murder. What is necessary is that the State prove that the attack by the defendant Pitts on the victim *636that you are considering involved either torture or conduct indicating a depraved mind or that the attack was so savagely brutal or outrageously cruel and violent that the adjectives wantonly vile or horrible or inhuman are justified. You must be satisfied that such conduct was present and you must be satisfied beyond a reasonable doubt.

We intimate no view on whether the evidence in the first trial, or on remand, was or will be sufficient to submit factor c(4)(c) to the jury in the event of a retrial of the penalty phase.
