A jury convicted Jason Mangum of the felony murder and armed robbery of Jerry Allen Clark and the armed robbery of Martha Jean Hollis.1 Because we conclude that Mangum was denied his Sixth *574Amendment right of confrontation, he is entitled to a new trial.
Rebecca Johnson, an acquaintance of Mangum, had information that the murder victim, Jerry Clark, would be coming to Georgia with a large sum of cash he had acquired from an insurance settlement. Clark and his companion, Martha Jean Hollis, were to be guests at Rebecca’s apartment. Rebecca and Mangum made plans to rob Clark when he arrived in Atlanta, and they solicited the help of Rebecca’s son, Wayne Johnson. On the day before the plot was to be carried out, Wayne told two friends that he and Mangum were planning to rob a man coming in from out of town.
Clark and Hollis arrived in Atlanta. While the two were alone in Rebecca’s apartment, two young males entered. Both intruders wore Halloween-type masks (one wore a werewolf mask), and hooded sweatshirts. They encountered Hollis in the living room where they demanded her jewelry at gunpoint and asked the location of her companion. Hollis directed one of the perpetrators to a bedroom where Clark was resting. The intruder returned to the living room a few minutes later with Clark’s money and then asked his accomplice if he should “waste” the couple. At that point, Clark walked into the living room and ordered the two to get out of the apartment. The armed intruder turned toward Clark and fired the fatal shot. Clark died as a result of a single gunshot to the abdomen fired from a .380 pistol.
After the shooting, Mangum disclosed to his teenage girlfriend that he robbed and shot a man and shared the proceeds of the robbery with Rebecca Johnson. It was also established that Mangum owned a werewolf mask and a .380 pistol, the same caliber as the murder weapon. A comparison was made of the shell casing recovered from the crime scene with other shell casings known to have been fired from Mangum’s pistol. Based on that information, a firearms examiner testified that the bullet fired at the crime scene had been fired from Mangum’s pistol.
1. The evidence was sufficient to enable a rational trier of fact to find Mangum guilty beyond a reasonable doubt of the crimes for which he was convicted. Jackson v. Virginia, 443 U. S. 307 (99 SC 2781, 61 LE2d 560) (1979). It follows that the court did not err in denying Mangum’s motion for directed verdict of acquittal made at the conclusion of the State’s case-in-chief, and renewed at the close of the evidence.
2. In a hearing conducted prior to the commencement of voir dire, trial counsel requested that the court order the production and in camera inspection of any juvenile court records which may pertain to certain State’s witnesses, to ascertain whether those witnesses *575had pending juvenile adjudications that could be used for impeachment as to bias or prejudice under the authority of Davis v. Alaska, 415 U. S. 308 (94 SC 1105, 39 LE2d 347) (1974).2 Initially, the prosecution declined to take a position with regard to the motion, but then maintained “that the juvenile records are under no condition to come in.” The court denied defendants’ request, stating that it would not “make an assessment as to whether or not somebody is on probation or had been on probation and then reveal that to [the defense].” When asked to clarify its ruling as to whether defense counsel would be permitted to cross-examine the witnesses concerning possible pending juvenile offenses, the court replied that it would disallow any inquiry at all concerning juvenile offenses.3
In large part, the State’s case-in-chief consisted of a series of juvenile witnesses, all of whom were acquaintances of Mangum’s and could connect him to discussions with the Johnsons concerning the robbery, or could tie him to the murder weapon.4 Mangum submits that these witnesses had extensive juvenile records and likely pending cases, but that the defense was unable to expose bias or motive on the part of the witnesses based on the theory that they were subject to the criminal justice process at the same time they were assisting the police. With respect to two of those witnesses, the defense was able to elicit limited testimony on cross-examination concerning pending juvenile prosecutions, but only because the witness or the prosecutor opened the door to such inquiry.5
*576In Davis v. Alaska, the Court held that the confrontation clause of the Sixth Amendment requires that a defendant in a state criminal prosecution be allowed to impeach the credibility of a prosecution witness by cross-examination directed at possible bias in favor of the State resulting from the witness’ probationary status as a juvenile delinquent, notwithstanding that such impeachment would conflict with the State’s asserted interest in preserving the confidentiality of juvenile delinquency proceedings. And in these circumstances, a criminal defendant’s rights under the confrontation clause are paramount to the State’s policy of protecting juvenile offenders. Davis v. Alaska, 415 U. S. at 319.
This Court recognized that Davis v. Alaska guarantees a defendant in a criminal trial “both the general right to cross-examine witnesses against him and the more specific right to cross-examine a key state’s witness concerning pending criminal charges against the witness.” Hines v. State, 249 Ga. 257, 259 (2) (290 SE2d 911) (1982). See also Baynes v. State, 218 Ga. App. 687 (4) (463 SE2d 144) (1995). Whether or not a “deal” has been made with the State is not crucial. Hines, supra.
What counts is whether the witness may be shading his testimony in an effort to please the prosecution. “A desire to cooperate may be formed beneath the conscious level, in a manner not apparent even to the witness, but such a subtle desire to assist the state nevertheless may cloud perception.” [Cits.]
Hines, supra at 260.
In the present case, the defense was thwarted in its attempts to discover information concerning juvenile records of the State’s witnesses and to have the court conduct an in camera examination of those records to determine whether they could be used for purposes deemed appropriate in Davis v. Alaska. It was confirmed at trial that at least two of those witnesses had juvenile offenses pending at the time. When the court restricted cross-examination based on the confidentiality of juvenile records and disallowed any inquiry into pending criminal charges against the witness in an effort to attack credibility “directed toward revealing possible biases, prejudices, or ulterior motives,” Hines, supra at 260 (2), the rule in Davis v. Alaska *577was violated.
We cannot agree with the State’s assertion that any error in the court’s ruling was harmless. A violation of the Sixth Amendment right of confrontation results in “constitutional error of the first magnitude.” (Punctuation omitted.) Davis v. Alaska, 415 U. S. at 318. “[B]efore a federal constitutional error can be held harmless, the court must be able to declare a belief that it was harmless beyond a reasonable doubt.” Chapman v. California, 386 U. S. 18, 24 (87 SC 824, 17 LE2d 705) (1967). The burden rests with the prosecution in making this showing. See State v. Hightower, 236 Ga. 58, 61 (222 SE2d 333) (1976) (State must show beyond a reasonable doubt that the error did not contribute to the verdict). “The fact that there was other sufficient evidence to convict does not make the error harmless; rather, the test is whether the evidence may have influenced the jury’s verdict.” Jones v. State, 265 Ga. 84, 86 (4) (453 SE2d 716) (1995).
Mangum’s conviction was based largely on circumstantial evidence, or hearsay testimony elicited from the juvenile witnesses. With respect to at least five prosecution witnesses, Mangum was denied the right “to expose to the jury the facts from which jurors, as the sole triers of fact and credibility, could appropriately draw inferences relating to the reliability of the witness.” Davis v. Alaska, 415 U. S. at 318. The State has not demonstrated that the limitation on Mangum’s Sixth Amendment right of confrontation, which pervaded the trial, was harmless beyond a reasonable doubt. Because we conclude that the error may well have influenced the verdict, Mangum is entitled to a new trial. See generally Starks v. State, 266 Ga. 547 (468 SE2d 376) (1996).
3. Mangum challenges several aspects of the jury instruction which merit discussion.
(a) Citing Coleman v. State, 271 Ga. 800 (8) (523 SE2d 852) (1999), Mangum asserts that an erroneous jury instruction relating to the definition of reasonable doubt violated his state and federal due process rights. Within the pattern instructions on reasonable doubt, the trial court added the gratuitous language, “neither does [reasonable doubt] mean a possibility that the defendant may be innocent.” In Coleman we considered the identical charge and we overruled a long line of cases which had previously approved the extraneous language.6 Nonetheless, in considering the charge as a whole, we found no reasonable likelihood that the jury applied a standard of proof less stringent than that required by due process. *578We also admonished that “continued use of the disapproved charge in disregard of this opinion may result in the reversal of future convictions.” Id. at 805 (8).
While we recognize that Mangum’s 1995 trial predated Coleman, and that the charging error is not likely to recur on retrial, we nevertheless recognize that the problem persists. See Bernoudy v. State, 245 Ga. App. 489 (2) (538 SE2d 150) (2000); Cowan v. State, 243 Ga. App. 388 (7) (531 SE2d 785) (2000). Thus, we restate our admonition in Coleman.
(b) Prior to the commencement of deliberations, the court instructed the jury on the requirements of unanimity, adding: “if you cannot unanimously agree on a verdict, the judge is required by law to declare a mistrial and retry the case before another jury.” In Harris v. State, 263 Ga. 526, 528 (6) (435 SE2d 669) (1993), we cautioned that “[although a predeliberation charge on unanimity is proper, informing the jury in such a charge of the consequences of a failure to achieve unanimity is disapproved.” Likewise, we hold that the challenged instruction in this case was certainly premature and an inaccurate statement of the law in a circumstance where the State elects not to pursue a retrial following mistrial resulting from a hung jury.
(c) A charge on the law of conspiracy was authorized by the evidence, as was a charge on admissibility of co-conspirators’ hearsay declarations. “A conspiracy may be inferred from the nature of the acts done, the relation of the parties, the interest of the alleged conspirators, and other circumstances.” (Citation and punctuation omitted.) Washington v. State, 268 Ga. 598, 601 (6) (492 SE2d 197) (1997). The trial evidence established that Mangum and the Johnsons plotted to perpetrate an armed robbery against the victims; that Man-gum and Wayne Johnson acted in furtherance of that plan by entering the residence and robbing both victims at gunpoint; and that Clark was killed during the course of that robbery.
(d) It was not error for the trial court to instruct the jury both on conspiracy and parties to a crime. “[I]t has been repeatedly held that a conspiracy may be proven and a jury charge may be given on conspiracy and parties to a crime even though a defendant is not indicted under those theories.” Huey v. State, 263 Ga. 840, 842 (3) (439 SE2d 656) (1994).
(e) Nonetheless, we agree with Mangum that the charge on conspiracy was deficient in that the court failed to specify that the jury must be satisfied beyond a reasonable doubt of the existence of a conspiracy before considering the hearsay declarations of a co-conspirator. See Suggested Pattern Jury Instructions, supra.
4. As our holding in Division 2 requires reversal, and no other error is raised which is likely to recur on retrial, we do not reach those enumerations of error.
*579 Judgment reversed.
All the Justices concur, except Sears, P. J, Hunstein and Carley, JJ., who dissent.The crimes took place on September 29, 1993. A true bill of indictment was returned on October 15, 1993, charging Mangum and co-defendants Rebecca Susan Johnson and Wayne Johnson with malice murder, felony murder, and armed robbery (two counts). Trial commenced on January 24, 1995, and on January 30, 1995, a jury found Mangum and both co-defendants guilty of felony murder and two counts of armed robbery. Mangum was sentenced on February 1, 1995 to life imprisonment, plus two concurrent 20-year terms. A motion for new trial was filed on March 2, 1995, and amended on June 26, 2000, July 6, 2000, and July 11,2000. After an evidentiary hearing, the amended motion for new trial was denied on October 6, 2000. A notice of appeal was filed on October 27, 2000. The case was *574docketed in this Court on January 10, 2001, and oral argument was heard on April 17, 2001.
At the pretrial hearing, counsel for co-defendant Rebecca Johnson informed the court that he had attempted to subpoena the juvenile records of certain witnesses for the State, but that he was denied direct access to those records. Counsel asked the court to order production of any juvenile records and to conduct an in camera inspection to determine whether any witnesses were currently on probation through the juvenile court or have open or pending cases in that court. Mangum’s trial counsel joined the motion.
Mangum’s counsel argued the necessity for cross-examination as follows:
My point is we think we know some of the problems some of the witnesses have had. And we think we know some of the rulings that the juvenile court has made. And if we ask some of the witnesses, for instance, weren’t you involved at a certain point in time in such and such an incident; if they say no, I have no idea what he’s talking about. ... I understand the court has said we cannot have access to those records, but what we were asking was could .we have access to those records to impeach him.
The defense attempted to impeach these witnesses with prior inconsistent statements given to officers during their investigation. When one of these witnesses stated he could not recall a prior statement to police, defense counsel inquired about his use of cocaine. The court immediately sustained an objection by the State and no further inquiry was made concerning criminal conduct on the part of the witness. Another witness testified that Rebecca Johnson had solicited his help in perpetrating the robbery, but that he declined.
One witness volunteered that he was supposed to be in court on the day following the murder. Over objection by the State, the court allowed inquiry into the probationary status of the witness. He disclosed that he was presently on probation in juvenile court for statutory rape and burglary.
A second witness was asked by the State on direct examination where he resided, and *576he identified a juvenile detention facility. As a result, defense counsel was permitted to cross-examine the witness as to the nature of the juvenile offense. But when the witness was asked whether the prosecutor could have him sent to “a tougher place” if she were displeased with him, the State objected and the court curtailed further questioning along these lines.
The charge did not conform to the Suggested Pattern Jury Instructions, Vol. II: Criminal Cases (2d ed. 1991), compiled by the Council of Superior Court Judges of Georgia.
