We review this case in banc primarily to give further consideration to two of Stano’s claims: his claim under Brady v. Maryland, 373 U.S. 83, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963); and his claim under United *899States v. Henry, 447 U.S. 264, 100 S.Ct. 2183, 65 L.Ed.2d 115 (1980).
Stano’s first trial ended in a mistrial after the jury failed to reach a unanimous verdict. The major evidence against Stano at this first trial consisted of the confessions that Stano made on March 6, 1981, and August 11 and 12, 1981, to detectives Crow and Manis. In the second trial, Stano was found guilty of first degree murder of Cathy Scharf, and sentenced to death. The evidence against Stano in this retrial was substantially the same, with the addition of a jailhouse confession to inmate Clarence Zacke. The principal theory of the defense was that Stano tended to confess falsely. As set out more fully in part I of Judge Fay’s opinion for the panel in this case, 883 F.2d 900, 903-04 (11th Cir.1989), Stano pursued his direct appeal and his post-conviction remedies under Rule 3.850 of the Florida Rules of Criminal Procedure, and then filed the instant Petition for Writ of Habe-as Corpus in federal district court. The district court denied relief, and Stano appealed to this court.
The procedural posture of this case is that Gerald Stano has had the benefit of a limited evidentiary hearing only on his ineffective assistance of counsel claim, not on his other claims. There has been no evi-dentiary hearing, either in state court or in federal court, on Stano’s Brady claim or his Henry claim.
If there has been no evidentiary hearing in state court on an issue raised on habeas corpus, one is required if the petitioner alleges facts which, if true, would entitle him to relief. Townsend v. Sain, 372 U.S. 293, 312, 83 S.Ct. 745, 757, 9 L.Ed.2d 770 (1963); Porter v. Wainwright, 805 F.2d 930, 933 (11th Cir.1986), cert. denied, 482 U.S. 918, 107 S.Ct. 3195, 96 L.Ed.2d 682 (1987). The petitioner will not be entitled to an evidentiary hearing when his claims are merely “conclusory allegations unsupported by specifics” or “contentions that in the face of the record are Blackledge v. Allison, 431 U.S. 63, 74, 97 S.Ct. 1621, 1629, 52 L.Ed.2d 136 (1977).
I. BRADY CLAIM
A Brady violation occurs where: (1) the prosecution suppressed evidence; (2) the evidence was favorable to the defendant; and (3) the evidence was material to the issues at trial. See United States v. Burroughs, 830 F.2d 1574, 1577-78 (11th Cir.1987), cert. denied, 485 U.S. 969, 108 S.Ct. 1243, 99 L.Ed.2d 442 (1988). Suppressed evidence is material when “there is a reasonable probability that ... the result of the proceeding would have been different” had the evidence been available to the defense. Pennsylvania v. Ritchie, 480 U.S. 39, 57, 107 S.Ct. 989, 1001, 94 L.Ed.2d 40 (1987) (quoting United States v. Bagley, 473 U.S. 667, 682, 105 S.Ct. 3375, 3383, 87 L.Ed.2d 481 (1985)) (plurality opinion of Blackmun, J.).
Specifically, Stano has alleged that the prosecution suppressed evidence that there was collusion between Crow, the police investigator; Donald Jacobson, Stano’s defense attorney during the investigative stage; and Dr. Ann McMillan, the defense psychologist during the investigative stage. The alleged purpose of this collusion was to exploit Stano’s mental vulnerabilities in order to coerce murder confessions, including confessions to the Scharf killing. Stano alleges that Dr. McMillan, at Jacobson’s suggestion, gave Crow psychological information that would make this coercion more likely to succeed. He alleges that Jacobson assisted Crow in coercing the confessions, and that Crow used this information and assistance in his on-going elicitation of confessions. Stano alleges that Crow, obviously, knew of this collusion and the effect on Stano’s confessions, and that such knowledge is imputed to the state.
Stano’s petition and supporting appendices allege the following.1 Stano was arrested on his first murder charge in April *9001980. J.W. Gadberry, the officer who had first brought Stano in, participated in the early investigation, which was led by Sergeant Paul Crow. Soon after Stano’s arrest, Don Jacobson was appointed as Sta-no’s attorney, and he hired Dr. Ann McMillan as a defense psychologist. Both Crow and Jacobson were interested in writing books about their work with Stano if he turned out to be a serial killer.2 There is evidence that Crow even hired a literary agent.3
Jacobson asked Dr. McMillan to find out if Stano was a serial killer and indicated that he was not interested in representing Stano unless he was. Jacobson instructed Dr. McMillan to tell Crow how best to interrogate Stano in order to elicit confessions, by exploiting Stano’s mental vulnerabilities.4 Crow used that psychological information in interrogating Stano, as described below.5 He maintained close contact with Stano day after day and deprived him of contact with others. There were frequent long interrogation sessions at which Crow would not allow anyone else to be present.6 Crow stated to a freelance writer that he could lead Stano to the correct result and that he would rehearse confessions with him.7 Gadberry, the police detective, was with Stano at the time of an early murder confession in another case arid stated that Crow led Stano to the body, not the reverse.8
Jacobson, an ex-FBI agent who also did some legal work for members of the police department, worked extensively with Crow and the state attorney. He often allowed members of the police investigatory team to interrogate Stano outside the presence of counsel.9 Jacobson helped formulate the questions Crow would address to Sta-no. They urged Stano to confess to more killings in order to become eligible for an insanity defense.10 Jacobson also advised Stano’s parents to talk freely with Crow and Dr. McMillan.11
The information given by Dr. McMillan to Crow included Stano’s psychological vulnerabilities. There is psychological evidence that Stano was susceptible to strong authority figures who relied on manipulation and that he could not appreciate the consequences of his confessions. Dr. McMillan now admits that she advised Crow to play on Stano’s “grandiosity.” 12 Other evidence suggests that Stano was likely to confess in order to gain attention. Gadberry, who was present at the early stage of the investigation, felt that Stano had an abnormal need for attention and affection due to mental illness, and that Crow exploited this. Another detective, who worked with Crow on another Stano *901murder investigation approximately eight months before the first Scharf confession, believed that in making confessions Stano “got carried away by delusions of grandeur.” 13
Stano’s first murder confessions to Crow (relating to other killings) occurred in April and May of 1980. In May and June of 1980, Crow and Detective Lehman interviewed Stano in the Van Haddocks murder. The transcript of these interviews, at which counsel is not present, includes instances of promises,14 threats,15 and coaching.16
Stano has alleged that the collusion between Jacobson, Dr. McMillan, and Crow continued and tainted the confessions to the Scharf killing on which the instant conviction was based. In March 1981, Crow, Jacobson, and Dr. McMillan met with Sta-no’s father, whom Jacobson had advised to cooperate with Crow.17 They asked Mr. Stano to convince Stano to confess to more killings. He was told that more confessions were necessary to save Stano’s life, because if a pattern of insanity were established Stano would not be executed. Crow then gave Mr. Stano specific information relevant to various murders to use in asking Stano to confess. When Mr. Stano met with his son, Mr. Stano cried and begged Stano to confess, explaining the insanity theory to him and encouraging him to talk to Crow about other murders. Stano asked his father to contact Crow; a few days later, on March 6,1981, Stano gave his first confession to the Scharf killing.
The evidence of collusion and coercion by Crow continued through the period of the second confession, which occurred on August 11 and 12, 1982. Crow had continued working with Stano on pending cases through late 1982. Detective Manis was contacted by Crow to the effect that one of Stano’s confessions matched Manis’s pending Scharf case. In January 1982, Manis, at Crow’s suggestion, spoke to Stano, who denied committing the Scharf murder.18 *902Crow continued to visit Stano often at the prison during this period. In April, Crow initiated another meeting between Stano and Manis, but when Manis arrived, Crow had been inside and said that Stano would not talk.19 During this entire time period, Crow and Stano were communicating: in June, Stano wrote to Crow and said he wanted to help by “telling you what you want to know about anything,” and asked for contact with Howard Pearl, a public defender.20 In July, Jacobson instructed him to make “a clean breast of everything” and that Crow was his best source; this letter had a covert copy to Crow.21 On August 10, Stano was transferred to Crow’s jail,22 and a memo was circulated restricting access to Stano to Crow only.23 On August 11, Manis interviewed Stano for IV2 hours, with Crow present part of the time; on August 12, 1982, the second Scharf confession was taped.24
Thus Stano has alleged that defense attorney Jacobson and defense psychologist McMillan colluded with the investigating detective, Crow, to take advantage of Sta-no’s psychological weaknesses and to induce Stano to confess to the Scharf killing without regard to the truth thereof, but in order to promote the ulterior motives of Jacobson and Crow for fame and fortune.25 Stano alleges that the March 6, 1981, and the August 11 and 12, 1982, confessions were thus coerced and tainted.
As noted above, to establish a violation of Brady, Stano must show that the omitted evidence — here, the alleged fact of the collusion among Crow, Jacobson, and McMillan — was favorable to the defense, was suppressed by the prosecution, and was material in that there is a reasonable probability that it would have changed the result of the trial had it been available to the defense. Undoubtedly, the alleged collusion among Crow, Jacobson, and McMillan, and the resulting effect on Stano’s confessions, if true, would have been information favorable to the defense. The defense strategy at trial was to discredit Sta-no’s confessions by showing that Stano had psychological weaknesses that led him to confess falsely. The suppressed evidence of collusion and coercion, including inter alia Crow’s knowledge of his own misconduct and that of Jacobson, the covert copy of Jacobson’s letter to Stano, and the tape of the prior confession revealing promises, threats, and coaching, all could have been used effectively at trial to further this defense strategy. The alleged facts of collu*903sion and coercion constitute significant impeachment of Stano’s confessions and would have substantially enhanced the defense strategy. Thus, we conclude that the first requirement — that the alleged facts be favorable to the defense — is clearly met.
With respect to whether or not the evidence of collusion was suppressed by the prosecution, we conclude that there are disputed facts which require an evidentiary hearing. Stano alleges that Crow was in charge of the investigation which produced the crucial confessions, and that Crow’s knowledge of the collusion was police knowledge that should have been disclosed pursuant to Brady. If Crow was part of the prosecution team in the Scharf case, then the state is responsible for his knowledge. United States v. Antone, 603 F.2d 566 (5th Cir.1979).26 In this regard, there are disputed issues of fact which require evidentiary development. On the one hand, Crow was a detective in a county other than the one in which the Scharf murder was prosecuted. On the other hand, there is evidence that Stano was committed to Crow’s custody at the time of the three confessions, that access to Stano was limited to Crow at the time of two of the confessions, and that Crow was involved in and perhaps in charge of the Scharf investigation.
Turning to the materiality prong of the Brady analysis, we conclude that if all of Stano’s allegations are true, there is a reasonable probability that the result of the guilt phase would have been different. We noted above that the suppressed evidence would have substantially strengthened the defense strategy at trial. If the March 6, 1981, and the August 11 and 12, 1982, confessions were coerced and subject to suppression as alleged, the linchpin of the prosecutor’s case would have been removed. Even with these confessions, a previous jury had been unable to find Stano guilty, and thus a mistrial resulted. See United States v. Agurs, 427 U.S. 97, 112—13, 96 S.Ct. 2392, 2401-2402, 49 L.Ed.2d 342 (1976); Carter v. Rafferty, 826 F.2d 1299, 1308-09 (3d Cir.1987), cert. denied, 484 U.S. 1011, 108 S.Ct. 711, 98 L.Ed.2d 661 (1988) (assessment of the materiality of the suppressed evidence depends in part on the strength or fragility of the state’s case as a whole). There was very little other evidence linking Stano to the crime. His jailhouse confession to Zacke was subject to forceful impeachment at trial;27 and the Zacke confession may in any event have been in violation of United States v. Henry, 447 U.S. 264, 100 S.Ct. 2183, 65 L.Ed.2d 115 (1980) (see infra). The alleged misconduct reflected in the suppressed evidence would have been enthusiastically exploited by defense counsel,28 would have fit the defense strategy like a glove, and would have provided forceful impeachment of the major evidence against Stano — i.e., the confessions to Crow and Manis. We conclude that the materiality prong has been satisfied.
The state argues that the result would not have been different because Stano testified at sentencing and confessed to the killing.29 Even if we assume that Stano’s *904later testimony at sentencing is properly considered in determining whether there is a reasonable probability that the result of the preceding guilt phase would have been different,30 Stano’s sentencing testimony was unequivocal that he did not kill Cathy Scharf.31
*905For the foregoing reasons, we conclude that Stano is entitled to an evidentiary hearing on his Brady claim.
II. HENRY CLAIM
Stano alleges that the testimony of Zacke relating the jailhouse confession by Stano violates United States v. Henry, 447 U.S. 264, 100 S.Ct. 2183, 65 L.Ed.2d 115 (1980). He alleges that Moxley, who prosecuted both Stano and Zacke, promised leniency to Zacke in exchange for testimony about other murders.32 He also alleges that the prosecutor directed that Zacke and Stano be placed in proximity to each other in the jail.33 Stano argues that Zacke was thus an agent of the state who elicited statements from him in violation of Henry. The state asserts a procedural bar because of Stano’s failure to assert the Henry claim during the 1986 proceedings in state court pursuant to Florida Rule of Criminal Procedure 3.850. Because an evidentiary hearing must take place on remand in any event, the interests of judicial economy indicate that the facts relevant to this claim, and any cause and prejudice to excuse the procedural default, be developed at the hearing, and that the claim as thus developed be addressed in the first instance by the district court.
III. OTHER CLAIMS
1. Johnson v. Mississippi Claim
After the proceedings in the district court in this case, two of the prior convictions which were relied upon by the state in the sentencing phase were found to be invalid by a panel of this court. Stano v. Dugger, 889 F.2d 962 (11th Cir.1989). For this reason, Stano argues that his sentence in this case must be vacated, citing Johnson v. Mississippi, 486 U.S. 578, 108 S.Ct. 1981, 100 L.Ed.2d 575 (1988).
On remand the district court shall address this argument in the first instance.
2. Ineffective Assistance of Counsel
a. Stano claims that his trial counsel, Russo and Friedland, were ineffective for failing to seek suppression of the several confessions to the Scharf killing and the confessions which formed the basis of the prior convictions introduced at sentencing. Russo and Friedland testified at the limited evidentiary hearing in district court that they did not know of the potential grounds for challenging the confessions that have now emerged — i.e., the alleged collusion between Jacobson, Dr. McMillan, and Crow which is the basis of the Brady claim; and the alleged agreement (i.e., agency) between Zacke and the prosecutor which forms the basis of the Henry claim.34
*906Upon careful consideration of the particularized and voluminous facts alleged in support of the Brady and Henry claims, together with the testimony of Russo and Friedland, we are satisfied that it was not reasonably possible for Russo and Fried-land to have suspected the misconduct on the part of the state and previous defense counsel which forms the basis of the Brady and Henry claims. Accordingly, we affirm the judgment of the district court denying relief on the claim of ineffective assistance of counsel for failure to challenge the confessions.
b. Stano’s other claims of ineffective assistance of counsel are without merit for the reasons set forth by Judge Fay in the panel opinion. We affirm the judgment of the district court denying relief with respect to these claims of ineffective assistance of counsel.
3. Evidentiary Claims
We agree with the panel and the district court that Stano’s several evidentiary claims do not warrant relief. We affirm the judgment of the district court denying relief with respect to these evidentiary claims.
4. Remaining Claims
The remaining claims urged by Stano have no merit for the reasons set forth by Judge Fay in the panel opinion. We affirm the judgment of the district court denying relief with respect to these claims.

. Not all of the following evidence is Brady material. However, it is useful to view the Brady material in the context of the relevant allegations which support the need for an evidentiary hearing.

Stano: What do you mean by that?
Crow: Out from the groups.
Stano: No, I don’t want no damned single cell.
Lehman: You’re gonna want, Gerald, believe me ... there’s a few people out here that are out to slit your ... throat.

. The following are several examples from the interrogation:

Lehman: You ever see a Governor’s warrant?.... It comes through with goddamned ribbons and doilies on it and it's like a goddamned skull. And it says you’re gone whether you like it or not....
Crow: We gotta get some clout so we can keep you in the state.
Crow: You got problems.
Stano: Thanks.
Crow: More problems than you think. Because two bodies is not going to make you eligible for insanity.

Stano: They think I did ...
Lehman: I don’t want to see you get the chair. There’s a guy coming up to get the chair next week in Georgia ... I can’t help but think that somewhere along the line you got the answers for us.

. This is one of many examples:
Lehman: Done a little research into this knife you're talking about, a retractable blade. The bone to the skull on Haddocks and the breast plate on Maher don’t jive up with what you're telling us what you used on them....
Crow: You had to use a stronger blade than that, Gerald.

. Petition at 160; Appendix 39 (Manis report); Advanced App. Vol. Ill, at. 972 (Manis's trial testimony).
. The state argues that the collusion between Jacobson, McMillan, and Crow was merely good trial strategy seeking to save Stano from the electric chair. However, this is but one perception of the facts. This interpretation of the facts is disputed by Stano, and Stano’s version of the facts is alleged with considerable particularity. Stano alleges that it was not iust good defense strategy, but rather that Jacobson and Crow were motivated by ulterior motives of fame and fortune, that they exploited Stano’s psychological weaknesses and fed Stano facts in order to obtain confessions without regard to their truth. Thus, Stano alleges that he was convicted on the basis of confessions to the Scharf killing, the truth of which was thus tainted and that the state had knowledge of this, but failed to disclose this Brady material. While the state’s version of the facts may well be borne out by the facts developed at the evidentiary hearing on remand, in the present posture of this case, we can only conclude that an evidentiary hearing is required.
. This case was decided prior to the close of business on September 30, 1981, and is binding precedent under Bonner v. City of Prichard, 661 F.2d 1206, 1209 (11th Cir.1981).
. In its closing argument, the state noted that Zacke was a five-time felon and had received concessions from the government for his testimony. The state invited the jury to consider Zacke's testimony "in conjunction with other established facts. And if it matches up reasonably well, I believe you’re allowed to infer that that person is being truthful.” Advanced App. Vol. Ill, at 1073.
. See Bowen v. Maynard, 799 F.2d 593, 613 (10th Cir.), cert. denied, 479 U.S. 962, 107 S.Ct. 458, 93 L.Ed.2d 404 (1986) ("The withheld evidence also raises serious questions about the manner, quality, and thoroughness of the investigation. ... A common trial tactic of defense lawyers is to discredit the caliber of the investigation ... and we may consider such use in assessing the Brady violation.”). In this case the materiality of the suppressed evidence far exceeds impeachment of investigative techniques and exceeds even mere misconduct. The alleged misconduct in this case undermines the reliability of the major evidence against Stano.
. The state also argues that Stano’s confession to Dr. Mussenden, a psychologist secured by Stano’s trial attorney to assist in the defense, is relevant to the materiality prong. However, this evidence was not introduced either at the guilt phase or the sentencing phase of Stano’s trial. The state could not have called Dr. Mus-*904senden as its own witness at trial because any communications between Stano and Dr. Mus-senden are protected by the attorney-client privilege. Pouncy v. State, 353 So.2d 640, 642 (Fla.App.1977). Moreover, under Florida's psychiatrist-patient privilege, any statement of this type is not admissible on the ultimate issue of guilt or innocence. Fla.Stat. § 90.503 (1979); Parkin v. State, 238 So.2d 817, 823 (Fla.1970); McMunn v. State, 264 So.2d 868, 870 (Fla.App.1972).
. We decline to address at this stage the novel issue of whether or not it is appropriate to consider Stano’s later sentencing testimony in deciding whether there is a reasonable probability that the result of the preceding guilt phase would have been different. Resolution of this issue may not be necessary in this case. See infra, note 31. If on remand it does become necessary to address this novel issue, the following sub-issues become relevant.
First, if on remand Stano’s March 6, 1981, and August 11 and 12, 1982, confessions are found to have been coerced and suppressible, then the district court should consider whether Stano’s sentencing testimony was induced by the former confessions and thus was fruit of the poisonous tree. Harrison v. United States, 392 U.S. 219, 88 S.Ct. 2008, 20 L.Ed.2d 1047 (1968); Smith v. Estelle, 527 F.2d 430 (5th Cir.1976). This sub-issue itself would require evidentiary development of the nexus between the early confessions and the sentencing testimony — i.e., whether the sentencing testimony was “induced” by the erroneous admission of the coerced confessions is itself a factual issue.
Second, if the district court determines on remand that Harrison, supra, is no bar to consideration of Stano’s sentencing testimony, then an issue of first impression in this circuit becomes relevant, i.e., whether the district court in analyzing the Brady materiality prong should weigh the significance of the suppressed evidence in light of the existing trial record, or whether it is appropriate for the district court to consider new evidence that the state might have, but did not, adduce. See Miller v. Angliker, 848 F.2d 1312, 1323 (2d Cir.), cert. denied, - U.S. -, 109 S.Ct. 224, 102 L.Ed.2d 214 (1988) ("We believe the state is not entitled to seek to minimize the materiality of the withheld information by arguing that it could have produced additional evidence at a fuller trial. Having avoided the need to make a full presentation by means of a plea agreement that immunized its presentation from attack, and having achieved the plea agreement only after withholding information that would have put teeth in the attack, the state could not be allowed to becloud the court’s already hypothetical analysis of the likely effect of the withheld information by adverting other evidence it might have adduced had it not procured the plea agreement.”); McDowell v. Dixon, 858 F.2d 945, 950 (4th Cir. 1988), cert. denied, - U.S. -, 109 S.Ct. 1172, 103 L.Ed.2d 230 (1989) (refusing to consider post-trial recantations of information found in suppressed material when making materiality determination); Lindsey v. King, 769 F.2d 1034, 1040, 1042 (5th Cir.1985) (giving no weight to prosecutor's claim that suppressed matter was not material because it was flawed by a typographical error). Although the above cases suggest that, in analyzing Brady's materiality prong, it is not appropriate to consider new evidence that the state might have, but did not, adduce, there is somewhat inconsistent authority in the different context of ineffective assistance of counsel. In analyzing the analogous prejudice prong of ineffective assistance of counsel, both the Supreme Court and this court have considered related evidence that the government would likely have asserted to rebut evidence that a defense attorney was allegedly ineffective for failing to adduce. Strickland v. Washington, 466 U.S. 668, 701, 104 S.Ct. 2052, 2071, 80 L.Ed.2d 674 (1984); Bertolotti v. Dugger, 883 F.2d 1503, 1516-19 (11th Cir.1989). However, neither the Supreme Court nor this court has addressed the issue in the Brady context.
Third, assuming arguendo that it is appropriate to consider related evidence which the government was likely to assert in rebuttal — i.e., assuming arguendo that the approach of the ineffective assistance of counsel cases is applied in the Brady context — the state nevertheless faces a significant hurdle. The evidence at issue in this case does not fit neatly into the pattern developed in the ineffective assistance of counsel cases. Had the suppressed Brady evidence in this case been disclosed and introduced at the guilt phase, it is not likely that the state would have rebutted that evidence with Stano’s sentencing testimony. Stano did not testify at the guilt phase and, obviously, the state had no way to require him to testify. On remand, the state will be free to suggest any other theory under which it would be appropriate to consider Sta-no’s sentencing testimony in analyzing Brady’s materiality prong.
. At sentencing, Stano repeatedly and unequivocally testified that he did not kill Cathy Scharf. However, he did admit that he had killed several specific young women and that he had pled guilty to those murders. Those convictions were introduced at sentencing. Stano also admitted that he had told Crow and Manis about murdering someone in the general manner they related, but he was unequivocal in his testimony that this individual was not Cathy Scharf, the victim of the crime for which he was on trial. *905The context of that statement was that Stano had heard all of the evidence at trial- — e.g., he had seen the picture introduced at trial of Cathy Scharf with her long blonde hair; he had seen the rings that were recovered from Cathy Scharf s body, including the metal ring with the Indian head design. With such precise knowledge, Stano may well have been able to conclude with certainty that the young woman whom he had murdered was not Cathy Scharf. In fact, this sentencing testimony is consistent with Stano’s taped confession in which he described the girl he confessed to killing as having darker hair, and in which he described her jewelry as being turquoise, both of which are at variance with Cathy Scharf’s blonde hair and the Indian head ring found on her body. While the state argues that Stano’s sentencing testimony was merely self-serving, in the present posture of this case in which no evidentiary hearing has been held, the most that can be said for the state’s position is that there is a dispute of fact as to whether Stano’s sentencing testimony could have any effect on Brady's materiality analysis.
. Petition at 275-76; Appendix 127 (April 15, 1983, statement of Zacke).

. In the state proceedings pursuant to Florida Rule of Criminal Procedure 3.850, Stano was offered a limited evidentiary hearing on ineffective assistance of counsel, but the offer was limited to the testimony of the two trial attorneys, Russo and Friedland. In the district court, such a limited evidentiary hearing was actually held; however, again, only Russo and Friedland were permitted to testify. Such a limited evidentiary hearing was clearly inadequate for the development of the facts relating to the collusion between Jacobson, McMillan, and Crow or for the development of facts relating to the agency of Zacke. However, the record as a whole (as indicated in the text) conclusively establishes that Russo and Fried-land could not in the exercise of reasonable diligence have discovered the misconduct which *906forms the basis for the potential challenges to the confessions.
