[282]*282Justice White
delivered an opinion, Parts I, II, and IV of which are the opinion of the Court, and Part III of which is a dissenting opinion.
The Arizona Supreme Court ruled in this case that respondent Oreste Fulminante’s confession, received in evidence at his trial for murder, had been coerced and that its use against him was barred by the Fifth and Fourteenth Amendments to the United States Constitution. The court also held that the harmless-error rule could not be used to save the conviction. We affirm the judgment of the Arizona court, although for different reasons than those upon which that court relied.
I
Early in the morning of September 14, 1982, Fulminante called the Mesa, Arizona, Police Department to report that his 11-year-old stepdaughter, Jeneane Michelle Hunt, was missing. He had been caring for Jeneane while his wife, Jeneane’s mother, was in the hospital. Two days later, Je-neane’s body was found in the desert east of Mesa. She had been shot twice in the head at close range with a large caliber weapon, and a ligature was around her neck. Because of the decomposed condition of the body, it was impossible to tell whether she had been sexually assaulted.
Fulminante’s statements to police concerning Jeneane’s disappearance and his relationship with her contained a number of inconsistencies, and he became a suspect in her killing. When no charges were filed against him, Fulminante left Arizona for New Jersey. Fulminante was later convicted in New Jersey on federal charges of possession of a firearm by a felon.
Fulminante was incarcerated in the Ray Brook Federal Correctional Institution in New York. There he became [283]*283friends with another inmate, Anthony Sarivola, then serving a 60-day sentence for extortion. The two men came to spend several hours a day together. Sarivola, a former police officer, had been involved in loansharking for organized crime but then became a paid informant for the Federal Bureau of Investigation. While at Ray Brook, he masqueraded as an organized crime figure. After becoming friends with Ful-minante, Sarivola heard a rumor that Fulminante was suspected of killing a child in Arizona. Sarivola then raised the subject with Fulminante in several conversations, but Ful-minante repeatedly denied any involvement in Jeneane’s death. During one conversation, he told Sarivola that Jeneane had been killed by bikers looking for drugs; on another occasion, he said he did not know what had happened. Sarivola passed this information on to an agent of the Federal Bureau of Investigation, who instructed Sarivola to find out more.
Sarivola learned more one evening in October 1983, as he and Fulminante walked together around the prison track. Sarivola said that he knew Fulminante was “starting to get some tough treatment and whatnot” from other inmates because of the rumor. App. 83. Sarivola offered to protect Fulminante from his fellow inmates, but told him, “ ‘You have to tell me about it,’ you know. I mean, in other words, ‘For me to give you any help.’ ” Ibid. Fulminante then admitted to Sarivola that he had driven Jeneane to the desert on his motorcycle, where he choked her, sexually assaulted her, and made her beg for her life, before shooting her twice in the head. Id., at 84-85.
Sarivola was released from prison in November 1983. Fulminante was released the following May, only to be arrested the next month for another weapons violation. On September 4, 1984, Fulminante was indicted in Arizona for the first-degree murder of Jeneane.
Prior to trial, Fulminante moved to suppress the statement he had given Sarivola in prison, as well as a second confes[284]*284sion he had given to Donna Sarivola, then Anthony Sarivola’s fiancée and later his wife, following his May 1984 release from prison. He asserted that the confession to Sarivola was coerced, and that the second confession was the “fruit” of the first. Id., at 6-8. Following the hearing, the trial court denied the motion to suppress, specifically finding that, based on the stipulated facts, the confessions were voluntary. Id., at 44, 63. The State introduced both confessions as evidence at trial, and on December 19, 1985, Fulminante was convicted of Jeneane’s murder. He was subsequently sentenced to death.
Fulminante appealed, arguing, among other things, that his confession to Sarivola was the product of coercion and that its admission at trial violated his rights to due process under the Fifth and Fourteenth Amendments to the United States Constitution. After considering the evidence at trial as well as the stipulated facts before the trial court on the motion to suppress, the Arizona Supreme Court held that the confession was coerced, but initially determined that the admission of the confession at trial was harmless error, because of the overwhelming nature of the evidence against Fulminante. 161 Ariz. 237, 778 P. 2d 602 (1988). Upon Fulminante’s motion for reconsideration, however, the court ruled that this Court’s precedent precluded the use of the harmless-error analysis in the case of a coerced confession. Id., at 262, 778 P. 2d, at 627. The court therefore reversed the conviction and ordered that Fulminante be retried without the use of the confession to Sarivola.1 Because of dif[285]*285fering views in the state and federal courts over whether the admission at trial of a coerced confession is subject to a harmless-error analysis, we granted the State’s petition for certiorari, 494 U. S. 1055 (1990). Although a majority of this Court finds that such a confession is subject to a harmless-error analysis, for the reasons set forth below, we affirm the judgment of the Arizona court.
II
We deal first with the State’s contention that the court below erred in holding Fulminante’s confession to have been coerced. The State argues that it is the totality of the circumstances that determines whether Fulminante’s confession was coerced, cf. Schneckloth v. Bustamonte, 412 U. S. 218, 226 (1973), but contends that rather than apply this standard, the Arizona court applied a “but for” test, under which the court found that but for the promise given by Sarivola, Fulminante would not have confessed. Brief for Petitioner 14-15. In support of this argument, the State points to the Arizona court’s reference to Bram v. United States, 168 U. S. 532 (1897). Although the Court noted in Bram that a confession cannot be obtained by “‘any direct or implied promises, however slight, nor by the exertion of any improper influence,’” id., at 542-543 (quoting 3 H. Smith & A. Keep, Russell on Crimes and Misdemeanors 478 (6th ed. 1896)), it is clear that this passage from Bram, which under current precedent does not state the standard for determining the voluntariness of a confession, was not relied on by the Arizona court in reaching its conclusion. Rather, the court cited this language as part of a longer quotation from an Arizona case which accurately described the State’s burden of proof for establishing voluntariness. See 161 Ariz., at 244, 778 P. 2d, at 609 (citing State v. Thomas, 148 Ariz. 225, 227, 714 P. 2d 395, 397 (1986); Malloy v. Hogan, 378 U. S. 1, 7 (1964); and Bram, supra, at 542-543). Indeed, the Arizona Supreme Court stated that a “determination regarding [286]*286the voluntariness of a confession . . . must be viewed in a totality of the circumstances,” 161 Ariz., at 243, 778 P. 2d, at 608, and under that standard plainly found that Fulminante’s statement to Sarivola had been coerced.
In applying the totality of the circumstances test to determine that the confession to Sarivola was coerced, the Arizona Supreme Court focused on a number of relevant facts. First, the court noted that “because [Fulminante] was an alleged child murderer, he was in danger of physical harm at the hands of other inmates.” Ibid. In addition, Sarivola was aware that Fulminante had been receiving “ ‘rough treatment from the guys.’” Id., at 244, n. 1, 778 P. 2d, at 609, n. 1. Using his knowledge of these threats, Sarivola offered to protect Fulminante in exchange for a confession to Je-neane’s murder, id., at 243, 778 P. 2d, at 608, and “[i]n response to Sarivola’s offer of protection, [Fulminante] confessed.” Id., at 244, 778 P. 2d, at 609. Agreeing with Ful-minante that “Sarivola’s promise was ‘extremely coercive,’” id., at 243, 778 P. 2d, at 608, the Arizona court declared: “[T]he confession was obtained as a direct result of extreme coercion and was tendered in the belief that the defendant’s life was in jeopardy if he did not confess. This is a true coerced confession in every sense of the word.” Id., at 262, 778 P. 2d, at 627.2
[287]*287We normally give great deference to the factual findings of the state court. Davis v. North Carolina, 384 U. S. 737, 741 (1966); Haynes v. Washington, 373 U. S. 503, 515 (1963); Culombe v. Connecticut, 367 U. S. 568, 603-604 (1961). Nevertheless, “the ultimate issue of ‘voluntariness’ is a legal question requiring independent federal determination.” Miller v. Fenton, 474 U. S. 104, 110 (1985). See also Mincey v. Arizona, 437 U. S. 385, 398 (1978); Davis, supra, at 741-742; Haynes, supra, at 515; Chambers v. Florida, 309 U. S. 227, 228-229 (1940).
Although the question is a close one, we agree with the Arizona Supreme Court’s conclusion that Fulminante’s confession was coerced.3 The Arizona Supreme Court found a credible threat of physical violence unless Fulminante confessed. Our cases have made clear that a finding of coercion need not depend upon actual violence by a government agent;4 a credible threat is sufficient. As we have said, “coercion can be mental as well as physical, and . . . the blood of the accused is not the only hallmark of an unconstitutional inquisition.” Blackburn v. Alabama, 361 U. S. 199, 206 (1960). See also Culombe, supra, at 584; Reck v. Pate, 367 U. S. 433, 440-441 (1961); Rogers v. Richmond, 365 U. S. 534, 540 (1961); Payne v. Arkansas, 356 U. S. 560, 561 [288]*288(1958); Watts v. Indiana, 338 U. S. 49, 52 (1949). As in Payne, where the Court found that a confession was coerced because the interrogating police officer had promised that if the accused confessed, the officer would protect the accused from an angry mob outside the jailhouse door, 356 U. S., at 564-565, 567, so too here, the Arizona Supreme Court found that it was fear of physical violence, absent protection from his friend (and Government agent) Sarivola, which motivated Fulminante to confess. Accepting the Arizona court’s finding, permissible on this record, that there was a credible threat of physical violence, we agree with its conclusion that Fulminante’s will was overborne in such a way as to render his confession the product of coercion.

Four of us, Justices Marshall, Blackmun, Stevens, and myself, would affirm the judgment of the Arizona Supreme Court on the ground that the harmless-error rule is inapplicable to erroneously admitted coerced confessions. We thus disagree with the Justices who have a contrary view.
The majority today abandons what until now the Court has regarded as the “axiomatic [proposition] that a defendant in a criminal case is deprived of due process of law if his conviction is founded, in whole or in part, upon an involuntary confession, without regard for the truth or falsity of the confession, Rogers v. Richmond, 365 U. S. 534 [(1961)], and even though there is ample evidence aside from the confession to support the conviction. Malinski v. New York, 324 U. S. 401 [(1945)]; Stroble v. California, 343 U. S. 181 [(1952)]; Payne v. Arkansas, 356 U. S. 560.” Jackson v. Denno, 378 U. S. 368, 376 (1964). The Court has repeatedly stressed that the view that the admission of a coerced confession can be harmless error because of the other evidence to support the verdict is “an impermissible doctrine,” Lynumn v. Illinois, 372 U. S. 528, 537 (1963); for “the admission in ev[289]*289idence, over objection, of the coerced confession vitiates the judgment because it violates the Due Process Clause of the Fourteenth Amendment,” Payne, supra, at 568. See also Rose v. Clark, 478 U. S. 570, 578, n. 6 (1986); New Jersey v. Portash, 440 U. S. 450, 459 (1979); Lego v. Twomey, 404 U. S. 477, 483 (1972); Chapman v. California, 386 U. S. 18, 23, and n. 8 (1967); Haynes v. Washington, supra, at 518; Blackburn v. Alabama, supra, at 206; Spano v. New York, 360 U. S. 315, 324 (1959); Brown v. Allen, 344 U. S. 443, 475 (1953); Stroble v. California, 343 U. S. 181, 190 (1952); Gallegos v. Nebraska, 342 U. S. 55, 63 (1951); Haley v. Ohio, 332 U. S. 596, 599 (1948); Malinski v. New York, 324 U. S. 401, 404 (1945); Lyons v. Oklahoma, 322 U. S. 596, 597, n. 1 (1944). As the decisions in Haynes and Payne, supra, show, the rule was the same even when another confession of the defendant had been properly admitted into evidence. Today, a majority of the Court, without any justification, cf. Arizona v. Rumsey, 467 U. S. 203, 212 (1984), overrules this vast body of precedent without a word and in so doing dislodges one of the fundamental tenets of our criminal justice system.
In extending to coerced confessions the harmless-error rule of Chapman v. California, supra, the majority declares that because the Court has applied that analysis to numerous other “trial errors,” there is no reason that it should not apply to an error of this nature as well. The four of us remain convinced, however, that we should abide by our cases that have refused to apply the harmless-error rule to coerced confessions, for a coerced confession is fundamentally different from other types of erroneously admitted evidence to which the rule has been applied. Indeed, as the majority concedes, Chapman itself recognized that prior cases “have indicated that there are some constitutional rights so basic to a fair trial that their infraction can never be treated as harmless error,” and it placed in that category the constitutional rule against using a defendant’s coerced confession against [290]*290him at his criminal trial. 386 U. S., at 23, and n. 8 (emphasis added). Moreover, cases since Chapman have reiterated the rule that using a defendant’s coerced confession against him is a denial of due process of law regardless of the other evidence in the record aside from the confession. Lego v. Twomey, supra, at 483; Mincey v. Arizona, 437 U. S., at 398; New Jersey v. Portash, supra, at 459; Rose v. Clark, supra, at-577, 578, and n. 6.
Chapman specifically noted three constitutional errors that could not be categorized as harmless error: using a coerced confession against a defendant in a criminal trial, depriving a defendant of counsel, and trying a defendant before a biased judge. The majority attempts to distinguish the use of a coerced confession from the other two errors listed in Chapman first by distorting the decision in Payne, and then by drawing a meaningless dichotomy between “trial errors” and “structural defects” in the trial process. Viewing Payne as merely rejecting a test whereby the admission of a coerced confession could stand if there were “sufficient evidence,” other than the confession, to support the conviction, the majority suggests that the Court in Payne might have reached a different result had it been considering a harmless-error test. Post, at 309 (opinion of Rehnquist, C. J.). It is clear, though, that in Payne the Court recognized that regardless of the amount of other evidence, “the admission in evidence, over objection, of the coerced confession vitiates the judgment,” because “where, as here, a coerced confession constitutes a part of the evidence before the jury and a general verdict is returned, no one can say what credit and weight the jury gave to the confession.” 356 U. S., at 568. The inability to assess its effect on a conviction causes the admission at trial of a coerced confession to “defy analysis by ‘harmless-error’ standards,” cf. post, at 309 (opinion of Rehnquist, C. J.), just as certainly as do deprivation of counsel and trial before a biased judge.
[291]*291The majority also attempts to distinguish “trial errors” which occur “during the presentation of the case to the jury,” post, at 307, and which it deems susceptible to harmless-error analysis, from “structural defects in the constitution of the trial mechanism,” post, at 309, which the majority concedes cannot be so analyzed. This effort fails, for our jurisprudence on harmless error has not classified so neatly the errors at issue. For example, we have held susceptible to harmless-error analysis the failure to instruct the jury on the presumption of innocence, Kentucky v. Whorton, 441 U. S. 786 (1979), while finding it impossible to analyze in terms of harmless error the failure to instruct a jury on the reasonable-doubt standard, Jackson v. Virginia, 443 U. S. 307, 320, n. 14 (1979). These cases cannot be reconciled by labeling the former “trial error” and the latter not, for both concern the exact same stage in the trial proceedings. Rather, these cases can be reconciled only by considering the nature of the right at issue and the effect of an error upon the trial. A jury instruction on the presumption of innocence is not constitutionally required in every case to satisfy due process, because such an instruction merely offers an additional safeguard beyond that provided by the constitutionally required instruction on reasonable doubt. See Whorton, supra, at 789; Taylor v. Kentucky, 436 U. S. 478, 488-490 (1978). While it may be possible to analyze as harmless the omission of a presumption of innocence instruction when the required reasonable-doubt instruction has been given, it is impossible to assess the effect on the jury of the omission of the more fundamental instruction on reasonable doubt. In addition, omission of a reasonable-doubt instruction, though a “trial error,” distorts the very structure of the trial because it creates the risk that the jury will convict the defendant even if the State has not met its required burden of proof. Cf. Cool v. United States, 409 U. S. 100, 104 (1972); In re Winship, 397 U. S. 358, 364 (1970).
[292]*292These same concerns counsel against applying harmless-error analysis to the admission of a coerced confession. A defendant’s confession is “probably the most probative and damaging evidence that can be admitted against him,” Cruz v. New York, 481 U. S. 186, 195 (1987) (White, J., dissenting), so damaging that a jury should not be expected to ignore it even if told to do so, Bruton v. United States, 391 U. S. 123, 140 (1968) (White, J., dissenting), and because in any event it is impossible to know what credit and weight the jury gave to the confession. Cf. Payne, supra, at 568. Concededly, this reason is insufficient to justify a per se bar to the use of any confession. Thus, Milton v. Wainwright, 407 U. S. 371 (1972), applied harmless-error analysis to a confession obtained and introduced in circumstances that violated the defendant’s Sixth Amendment right to counsel.5 Similarly, the Courts of Appeals have held that the introduction of incriminating statements taken from defendants in violation of Miranda v. Arizona, 384 U. S. 436 (1966), is subject to treatment as harmless error.6
Nevertheless, in declaring that it is “impossible to create a meaningful distinction between confessions elicited in violation of the Sixth Amendment and those in violation of the Fourteenth Amendment,” post, at 312 (opinion of Rehnquist, C. J.), the majority overlooks the obvious. Neither Milton v. Wainwright nor any of the other cases upon which [293]*293the majority relies involved a defendant’s coerced confession, nor were there present in these cases the distinctive reasons underlying the exclusion of coerced incriminating statements of the defendant.7 First, some coerced confessions may be untrustworthy. Jackson v. Denno, 378 U. S., at 385-386; Spano v. New York, 360 U. S., at 320. Consequently, admission of coerced confessions may distort the truth-seeking function of the trial upon which the majority focuses. More importantly, however, the use of coerced confessions, “whether true or false,” is forbidden “because the methods used to extract them offend an underlying principle in the enforcement of our criminal law: that ours is an accusatorial and not an inquisitorial system — a system in which the State must establish guilt by evidence independently and freely secured and may not by coercion prove its charge against an accused out of his own mouth,” Rogers v. Richmond, 365 U. S., at 540-541; see also Lego, 404 U. S., at 485. This reflects the “strongly felt attitude of our society that important human values are sacrificed where an agency of the government, in the course of securing a conviction, wrings a confession out of an accused against his will,” Blackburn v. Alabama, 361 U. S., at 206-207, as well as “the deep-rooted feeling that the police must obey the law while enforcing the law; that in the end life and liberty can be as much endangered from illegal methods used to convict those thought to be criminals as from the actual criminals themselves,” Spano, supra, at 320-321. Thus, permitting a coerced confession to be part of the evidence on which a jury is free to base its verdict of guilty is inconsistent with the thesis that ours is not an [294]*294inquisitorial system of criminal justice. Cf. Chambers v. Florida, 309 U. S., at 235-238.
As the majority concedes, there are other constitutional errors that invalidate a conviction even though there may be no reasonable doubt that the defendant is guilty and would be convicted absent the trial error. For example, a judge in a criminal trial “is prohibited from entering a judgment of conviction or directing the jury to come forward with such a verdict, see Sparf & Hansen v. United States, 156 U. S. 51, 105 (1895); Carpenters v. United States, 330 U. S. 395, 408 (1947), regardless of how overwhelmingly the evidence may point in that direction.” United States v. Martin Linen Supply Co., 430 U. S. 564, 572-573 (1977). A defendant is entitled to counsel at trial, Gideon v. Wainwright, 372 U. S. 335 (1963), and as Chapman recognized, violating this right can never be harmless error. 386 U. S., at 23, and n. 8. See also White v. Maryland, 373 U. S. 59 (1963), where a conviction was set aside because the defendant had not had counsel at a preliminary hearing without regard to the showing of prejudice. In Vasquez v. Hillery, 474 U. S. 254 (1986), a defendant was found guilty beyond reasonable doubt, but the conviction had been set aside because of the unlawful exclusion of members of the defendant’s race from the grand jury that indicted him, despite overwhelming evidence of his guilt. The error at the grand jury stage struck at fundamental values of our society and “undermine[d] the structural integrity of the criminal tribunal itself, and [was] not amenable to harmless-error review.” Id., at 263-264. Vasquez, like Chapman, also noted that rule of automatic reversal when a defendant is tried before a judge with a financial interest in the outcome, Tumey v. Ohio, 273 U. S. 510, 535 (1927), despite a lack of any indication that bias influenced the decision. Waller v. Georgia, 467 U. S. 39, 49 (1984), recognized that violation of the guarantee of a public trial required reversal without any showing of prejudice and even though the values [295]*295of a public trial may be intangible and unprovable in any particular case.
The search for truth is indeed central to our system of justice, but “certain constitutional rights are not, and should not be, subject to harmless-error analysis because those rights protect important values that are unrelated to the truth-seeking function of the trial.” Rose v. Clark, 478 U. S., at 587 (Stevens, J., concurring in judgment). The right of a defendant not to have his coerced confession used against him is among those rights, for using a coerced confession “abort[s] the basic trial process” and “render[s] a trial fundamentally unfair.” Id., at 577, 578, n. 6.
For the foregoing reasons the four of us would adhere to the consistent line of authority that has recognized as a basic tenet of our criminal justice system, before and after both Miranda and Chapman, the prohibition against using a defendant’s coerced confession against him at his criminal trial. Stare decisis is “of fundamental importance to the rule of law,” Welch v. Texas Dept. of Highways and Public Transportation, 483 U. S. 468, 494 (1987); the majority offers no convincing reason for overturning our long line of decisions requiring the exclusion of coerced confessions.
HH <J
Since five Justices have determined that harmless-error analysis applies to coerced confessions, it becomes necessary to evaluate under that ruling the admissibility of Fulmi-nante’s confession to Sarivola. Cf. Pennsylvania v. Union Gas Co., 491 U. S. 1, 45 (1989) (White, J., concurring in judgment in part and dissenting in part); id., at 57 (O’Connor, J., dissenting). Chapman v. California, 386 U. S., at 24, made clear that “before 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. ” The Court has the power to review the record de novo in order to determine an error’s harmlessness. See ibid.; Satterwhite v. [296]*296Texas, 486 U. S., at 258. In so doing, it must be determined whether the State has met its burden of demonstrating that the admission of the confession to Sarivola did not contribute to Fulminante’s conviction. Chapman, supra, at 26. Five of us are of the view that the State has not carried its burden and accordingly affirm the judgment of the court below reversing respondent’s conviction.
A confession is like no other evidence. Indeed, “the defendant’s own confession is probably the most probative and damaging evidence that can be admitted against him. . . . [T]he admissions of a defendant come from the actor himself, the most knowledgeable and unimpeachable source of information about his past conduct. Certainly, confessions have profound impact on the jury, so much so that we may justifiably doubt its ability to put them out of mind even if told to do so.” Bruton v. United States, 391 U. S., at 139-140 (White, J., dissenting). See also Cruz v. New York, 481 U. S., at 195 (White, J., dissenting) (citing Bruton). While some statements by a defendant may concern isolated aspects of the crime or may be incriminating only when linked to other evidence, a full confession in which the defendant discloses the motive for and means of the crime may tempt the jury to rely upon that evidence alone in reaching its decision. In the case of a coerced confession such as that given by Fulminante to Sarivola, the risk that the confession is unreliable, coupled with the profound impact that the confession has upon the jury, requires a reviewing court to exercise extreme caution before determining that the admission of the confession at trial was harmless.
In the Arizona Supreme Court’s initial opinion, in which it determined that harmless-error analysis could be applied to the confession, the court found that the admissible second confession to Donna Sarivola rendered the first confession to Anthony Sarivola cumulative. 161 Ariz., at 245-246, 778 P. 2d, at 610-611. The court also noted that circumstantial physical evidence concerning the wounds, the ligature around Jeneane’s neck, the location of the body, and the presence of [297]*297motorcycle tracks at the scene corroborated the second confession. Ibid. The court concluded that “due to the overwhelming evidence adduced from the second confession, if there had not been a first confession, the jury would still have had the same basic evidence to convict” Fulminante. Id., at 246, 778 P. 2d, at 611.
We have a quite different evaluation of the evidence. Our review of the record leads us to conclude that the State has failed to meet its burden of establishing, beyond a reasonable doubt, that the admission of Fulminante’s confession to Anthony Sarivola was harmless error. Three considerations compel this result.
First, the transcript discloses that both the trial court and the State recognized that a successful prosecution depended on the jury believing the two confessions. Absent the confessions, it is unlikely that Fulminante would have been prosecuted at all, because the physical evidence from the scene and other circumstantial evidence would have been insufficient to convict. Indeed, no indictment was filed until nearly two years after the murder.8 App. 2. Although the police had suspected Fulminante from the beginning, as the prosecutor acknowledged in his opening statement to the jury, “[W]hat brings us to Court, what makes this case fileable, and prosecutable and triable is that later, Mr. Fulminante confesses this crime to Anthony Sarivola and later, to Donna Sarivola, his wife. ” Id., at 65-66. After trial began, during a renewed hearing on Fulminante’s motion to suppress, the trial court opined, “You know, I think from what little I know about this trial, the character of this man [Sarivola] for truthfulness or untruthfulness and his credibility is the centerpiece of this case, is it not?” The prosecutor responded, “It’s very important, there’s no doubt.” Id., at 62. Finally, in his [298]*298closing argument, the prosecutor prefaced his discussion of the two confessions by conceding: “[W]e have a lot of [circumstantial] evidence that indicates that this is our suspect, this is the fellow that did it, but it’s a little short as far as saying that it’s proof that he actually put the gun to the girl’s head and killed her. So it’s a little short of that. We recognize that.” 10 Tr. 75 (Dec. 17, 1985).
Second, the jury’s assessment of the confession to Donna Sarivola could easily have depended in large part on the presence of the confession to Anthony Sarivola. Absent the admission at trial of the first confession, the jurors might have found Donna Sarivola’s story unbelievable. Fulminante’s confession to Donna Sarivola allegedly occurred in May 1984, on the day he was released from Ray Brook, as she and Anthony Sarivola drove Fulminante from New York to Pennsylvania. Donna Sarivola testified that Fulminante, whom she had never before met, confessed in detail about Jeneane’s brutal murder in response to her casual question concerning why he was going to visit friends in Pennsylvania instead of returning to his family in Arizona. App. 167-168. Although she testified that she was “disgusted” by Fulmi-nante's disclosures, id., at 169, she stated that she took no steps to notify authorities of what she had learned, id., at 172-173. In fact, she claimed that she barely discussed the matter with Anthony Sarivola, who was in the car and overheard Fulminante’s entire conversation with Donna. Id., at 174-175. Despite her disgust for Fulminante, Donna Sari-vola later went on a second trip with him. Id., at 173-174. Although Sarivola informed authorities that he had driven Fulminante to Pennsylvania, he did not mention Donna’s presence in the car or her conversation with Fulminante. Id., at 159-161. Only when questioned by authorities in June 1985 did Anthony Sarivola belatedly recall the confession to Donna more than a year before, and only then did he ask if she would be willing to discuss the matter with authorities. Id., at 90-92.
[299]*299Although some of the details in the confession to Donna Sarivola were corroborated by circumstantial evidence, many, including details that Jeneane was choked and sexually assaulted, were not. Id., at 186-188. As to other aspects of the second confession, including Fulminante’s motive and state of mind, the only corroborating evidence was the first confession to Anthony Sarivola.9 No. CR 142821 (Super. Ct. Maricopa County, Ariz., Feb. 11, 1986), pp. 3-4. Thus, contrary to what the Arizona Supreme Court found, it is clear that the jury might have believed that the two confessions reinforced and corroborated each other. For this reason, one confession was not merely cumulative of the other. While in some cases two confessions, delivered on different occasions to different listeners, might be viewed as being independent of each other, cf. Milton v. Wainwright, 407 U. S. 371 (1972), it strains credulity to think that the jury so viewed the two confessions in this case, especially given the close relationship between Donna and Anthony Sarivola.
[300]*300The jurors could also have believed that Donna Sarivola had a motive to lie about the confession in order to assist her husband. Anthony Sarivola received significant benefits from federal authorities, including payment for information, immunity from prosecution, and eventual placement in the federal Witness Protection Program. App. 79,114,129-131. In addition, the jury might have found Donna motivated by her own desire for favorable treatment, for she, too, was ultimately placed in the Witness Protection Program. Id., at 176, 179-180.
Third, the admission of the first confession led to the admission of other evidence prejudicial to Fulminante. For example, the State introduced evidence that Fulminante knew of Sarivola’s connections with organized crime in an attempt to explain why Fulminante would have been motivated to confess to Sarivola in seeking protection. Id., at 45-48, 67. Absent the confession, this evidence would have had no relevance and would have been inadmissible at trial. The Arizona Supreme Court found that the evidence of Sarivola’s connections with organized crime reflected on Sarivola’s character, not Fulminante’s, and noted that the evidence could have been used to impeach Sarivola. 161 Ariz., at 245-246, 778 P. 2d, at 610-611. This analysis overlooks the fact that had the confession not been admitted, there would have been no reason for Sarivola to testify and thus no need to impeach his testimony. Moreover, we cannot agree that the evidence did not reflect on Fulminante’s character as well, for it depicted him as someone who willingly sought out the company of criminals. It is quite possible that this evidence led the jury to view Fulminante as capable of murder.10
[301]*301Finally, although our concern here is with the effect of the erroneous admission of the confession on Fulminante’s conviction, it is clear that the presence of the confession also influenced the sentencing phase of the trial. Under Arizona law, the trial judge is the sentencer. Ariz. Rev. Stat. Ann. § 13-703(B) (1989). At the sentencing hearing, the admissibility of information regarding aggravating circumstances is governed by the rules of evidence applicable to criminal trials. § 13-703(C). In this case, “based upon admissible evidence produced at the trial,” No. CR 142821, supra, at 2, the judge found that only one aggravating circumstance existed beyond a reasonable doubt, i. e., that the murder was committed in “an especially heinous, cruel, and depraved manner.” Ibid.; see § 13-703(F)(6). In reaching this conclusion, the judge relied heavily on evidence concerning the manner of the killing and Fulminante’s motives and state of mind which could only be found in the two confessions. For example, in labeling the murder “cruel,” the judge focused in part on Fulminante’s alleged statements that he choked Jeneane and made her get on her knees and beg before killing her. No. CR 142821, supra, at 3. Although the circumstantial evidence was not inconsistent with this determination, neither was it sufficient to make such a finding beyond a reasonable doubt. Indeed, the sentencing judge acknowledged that the confessions were only partly corroborated by other evidence. Ibid.
In declaring that Fulminante “acted with an especially heinous and depraved state of mind,” the sentencing judge relied solely on the two confessions. Id., at 4. While the judge found that the statements in the confessions regarding the alleged sexual assault on Jeneane should not be considered on the issue of cruelty because they were not corroborated by other evidence, the judge determined that they were worthy of belief on the issue of Fulminante’s state of [302]*302mind. Ibid. The judge then focused on Anthony Sarivola’s statement that Fulminante had made vulgar references to Jeneane during the first confession, and on Donna Sarivola’s statement that Fulminante had made similar comments to her. Ibid. Finally, the judge stressed that Fulminante’s alleged comments to the Sarivolas concerning torture, choking, and sexual assault, “whether they all occurred or not,” ibid., depicted “a man who was bragging and relishing the crime he committed.” Id., at 5.
Although the sentencing judge might have reached the same conclusions even without the confession to Anthony Sarivola, it is impossible to say so beyond a reasonable doubt. Furthermore, the judge’s assessment of Donna Sarivola’s credibility, and hence the reliability of the second confession, might well have been influenced by the corroborative effect of the erroneously admitted first confession. Indeed, the fact that the sentencing judge focused on the similarities between the two confessions in determining that they were reliable suggests that either of the confessions alone, even when considered with all the other evidence, would have been insufficient to permit the judge to find an aggravating circumstance beyond a reasonable doubt as a requisite prelude to imposing the death penalty.
Because a majority of the Court has determined that Ful-minante’s confession to Anthony Sarivola was coerced and because a majority has determined that admitting this confession was not harmless beyond a reasonable doubt, we agree with the Arizona Supreme Court’s conclusion that Ful-minante is entitled to a new trial at which the confession is not admitted. Accordingly the judgment of the Arizona Supreme Court is
Affirmed.
