On the afternoon of October 28, 1974, undercover police officer Barry Headricks of the Metropolitan Area Narcotics Squad knocked on the door of an apartment in Tucson, Ariz., occupied by the petitioner, Rufus Mincey. Earlier in the day, Officer Headricks had allegedly arranged to purchase a quantity of heroin from Mincey and had left, ostensibly to obtain money. On his return he was accompanied by nine other plainclothes policemen and a deputy county attorney. The door was opened by John Hodgman, one of three acquaintances of Mincey who were in the living room of the apartment. Officer Headricks slipped inside and moved quickly into the bedroom. Hodgman attempted to slam the door in order to keep the other officers from entering, but was pushed back against the wall. As the police entered the apartment, a rapid volley of shots was heard from the bedroom. Officer Headricks emerged and collapsed on the floor. When other officers entered the bedroom they found Mincey lying on the floor, wounded and semiconscious. Officer Headricks died a few hours later in the hospital.

The petitioner was indicted for murder, assault,1 and three counts of narcotics offenses. He was tried at a single trial and convicted on all the charges. At his trial and on appeal, he contended that evidence used against him had been unlawfully seized from his apartment without a warrant and that statements used to impeach his credibility were inadmissible because they had not been made voluntarily. The Arizona Supreme Court reversed the murder and assault convictions on state-law grounds,2 but affirmed the narcotics convictions. 115 Ariz. 472, 566 P.2d 273. It held that the warrantless search of a homicide scene is permissible under the Fourth and Fourteenth Amendments and that Mincey's statements were voluntary. We granted certiorari to consider these substantial constitutional questions. 434 U.S. 902, 98 S.Ct. 295, 54 L.Ed.2d 188.

* The first question presented is whether the search of Mincey's apartment was constitutionally permissible. After the shooting, the narcotics agents, thinking that other persons in the apartment might have been injured, looked about quickly for other victims. They found a young woman wounded in the bedroo closet and Mincey apparently unconscious in the bedroom, as well as Mincey's three acquaintances (one of whom had been wounded in the head) in the living room. Emergency assistance was requested, and some medical aid was administered to Officer Headricks. But the agents refrained from further investigation, pursuant to a Tucson Police Department directive that police officers should not investigate incidents in which they are involved. They neither searched further nor seized any evidence; they merely guarded the suspects and the premises.

Within 10 minutes, however, homicide detectives who had heard a radio report of the shooting arrived and took charge of the investigation. They supervised the removal of Officer Headricks and the suspects, trying to make sure that the scene was disturbed as little as possible, and then proceeded to gather evidence. Their search lasted four days,3 during which period the entire apartment was searched, photographed, and diagrammed. The officers opened drawers, closets, and cupboards, and inspected their contents; they emptied clothing pockets; they dug bullet fragments out of the walls and floors; they pulled up sections of the carpet and removed them for examination. Every item in the apartment was closely examined and inventoried, and 200 to 300 objects were seized. In short, Mincey's apartment was subjected to an exhaustive and intrusive search. No warrant was ever obtained.

The petitioner's pretrial motion to suppress the fruits of this search was denied after a hearing. Much of the evidence introduced against him at trial (including photographs and diagrams, bullets and shell casings, guns, narcotics, and narcotics paraphernalia) was the product of the four-day search of his apartment. On appeal, the Arizona Supreme Court reaffirmed previous decisions in which it had held that the warrantless search of the scene of a homicide is constitutionally permissible.4 It stated its ruling as follows:

"We hold a reasonable, warrantless search of the scene of a homicide—or of a serious personal injury with likelihood of death where there is reason to suspect foul play— does not violate the Fourth Amendment to the United States Constitution where the law enforcement officers were legally on the premises in the first instance. . . . For the search to be reasonable, the purpose must be limited to determining the circumstances of death and the scope must not exceed that purpose. The search must also begin within a reasonable period following the time when the officials first learn of the murder (or potential murder)." 115 Ariz., at 482, 566 P.2d, at 283.

Since the investigating homicide detectives knew that Officer Headricks was seriously injured, began the search promptly upon their arrival at the apartment, and searched only for evidence either establishing the circumstances of death or "relevant to motive and intent or knowledge (narcotics, e. g.)," id., at 483, 566 P.2d, at 284, the court found that the warrantless search of the petitioner's apartment had not violated the Fourth and Fourteenth Amendments.

We cannot agree. The Fourth Amendment proscribes all unreasonable searches and seizures, and it is a cardinal principle that "searches onducted outside the judicial process, without prior approval by judge or magistrate, are per se unreasonable under the Fourth Amendment—subject only to a few specifically established and well-delineated exceptions." Katz v. United States, 389 U.S. 347, 357, 88 S.Ct. 507, 514, 19 L.Ed.2d 576 (footnotes omitted); see also South Dakota v. Opperman, 428 U.S. 364, 381, 96 S.Ct. 3092, 3103, 49 L.Ed.2d 1000 (POWELL, J., concurring); Coolidge v. New Hampshire, 403 U.S. 443, 481, 91 S.Ct. 2022, 2045, 29 L.Ed.2d 564; Vale v. Louisiana, 399 U.S. 30, 34, 90 S.Ct. 1969, 1971, 26 L.Ed.2d 409; Terry v. Ohio, 392 U.S. 1, 20, 88 S.Ct. 1868, 1879, 20 L.Ed.2d 889; Trupiano v. United States, 334 U.S. 699, 705, 68 S.Ct. 1229, 1232, 92 L.Ed. 1663. The Arizona Supreme Court did not hold that the search of the petitioner's apartment fell within any of the exceptions to the warrant requirement previously recognized by this Court, but rather that the search of a homicide scene should be recognized as an additional exception.

Several reasons are advanced by the State to meet its "burden . . . to show the existence of such an exceptional situation" as to justify creating a new exception to the warrant requirement. See Vale v. Louisiana, supra, 399 U.S., at 34, 90 S.Ct., at 1971; United States v. Jeffers, 342 U.S. 48, 51, 72 S.Ct. 93, 95, 96 L.Ed. 59. None of these reasons, however, persuades us of the validity of the generic exception delineated by the Arizona Supreme Court.

The first contention is that the search of the petitioner's apartment did not invade any constitutionally protected right of privacy. See Katz v. United States, supra. This argument appears to have two prongs. On the one hand, the State urges that by shooting Officer Headricks, Mincey forfeited any reasonable expectation of privacy in his apartment. We have recently rejected a similar waiver argument in Michigan v. Tyler, 436 U.S. 499, 505-506, 98 S.Ct. 1942, 1948, 56 L.Ed.2d 486; it suffices here to say that this reasoning would impermissibly convict the suspect even before the evidence against him was gathered.5 On the other hand, the State contends that the police entry to arrest Mincey was so great an invasion of his privacy that the additional intrusion caused by the search was constitutionally irrelevant. But this claim is hardly tenable in light of the extensive nature of this search. It is one thing to say that one who is legally taken into police custody has a lessened right of privacy in his person. See United States v. Edwards, 415 U.S. 800, 808-809, 94 S.Ct. 1234, 1239, 39 L.Ed.2d 771; United States v. Robinson, 414 U.S. 218, 94 S.Ct. 467, 38 L.Ed.2d 427. It is quite another to argue that he also has a lessened right of privacy in his entire house. Indeed this very argument was rejected when it was advanced to support the warrantless search of a dwelling where a search occurred as "incident" to the arrest of its occupant. Chimel v. California, 395 U.S. 752, 766 n. 12, 89 S.Ct. 2034, 2042, 23 L.Ed.2d 685. Thus, this search cannot be justified on the ground that no constitutionally protected right of privacy was invaded.

The State's second argument in support of its categorical exception to the warrant requirement is that a possible homicide presents an emergency situation demanding immediate action. We do not question the right of the police to respond to emergency situations. Numerous state6 and federal7 cases have recognized that the Fourth Amendment does not bar police officers from making warrantless entries and searches when they reasonably believe that a person within is in need of immediate aid. Similarly, when the police come upon the scene of a homicide they may make a prompt warrantless search of the area to see if there are other victims or if a killer is still on the premises. Cf. Michigan v. Tyler, supra, 436 U.S., at 509-510, 98 S.Ct., at 1950-1951. "The need to protect or preserve life or avoid serious injury is justification for what would be otherwise illegal absent an exigency or emergency." Wayne v. United States, 115 U.S.App.D.C. 234, 241, 318 F.2d 205, 212 (opinion of Burger, J.). And the police may seize any evidence that is in plain view during the course of their legitimate emergency activities. Michigan v. Tyler, supra, 436 U.S., at 509-510, 98 S.Ct., at 1950-1951; Coolidge v. New Hampshire, 403 U.S., at 465-466, 91 S.Ct., at 2037-2038.

But a warrantless search must be "strictly circumscribed by the exigencies which justify its initiation," Terry v. Ohio, 392 U.S., at 25-26, 88 S.Ct., at 1882, and it simply cannot be contended that this search was justified by any emergency threatening life or limb. All the persons in Mincey's apartment had been located before the investigating homicide officers arrived there and began their search. And a four-day search that included opening dresser drawers and ripping up carpets can hardly be rationalized in terms of the legitimate concerns that justify an emergency search.

Third, the State points to the vital public interest in the prompt investigation of the extremely serious crime of murder. No one can doubt the importance of this goal. But the public interest in the investigation of other serious crimes is comparable. If the warrantless search of a homicide scene is reasonable, why not the warrantless search of the scene of a rape, a robbery, or a burglary? "No consideration relevant to the Fourth Amendment suggests any point of rational limitation" of such a doctrine. Chimel v. California, supra, 395 U.S., at 766, 89 S.Ct., at 2041.

Moreover, the mere fact that law enforcement may be made more efficient can never by itself justify disregard of the Fourth Amendment. Cf. Coolidge v. New Hampshire, supra, at 481, 91 S.Ct., at 2045. The investigation of crime would always be simplified if warrants were unnecessary. But the Fourth Amendment reflects the view of those who wrote the Bill of Rights that the privacy of a person's home and property may not be totally sacrificed in the name of maximum simplicity in enforcement of the criminal law. See United States v. Chadwick, 433 U.S. 1, 6-11, 97 S.Ct. 2476, 2481-2483, 53 L.Ed.2d 538. For this reason, warrants are generally required to search a person's home or his person unless "the exigencies of the situation" make the needs of law enforcement so compelling that the warrantless search is objectively reasonable under the Fourth Amendment. McDonald v. United States, 335 U.S. 451, 456, 69 S.Ct. 191, 193, 93 L.Ed. 153, Johnson v. United States, 333 U.S. 10, 14-15, 68 S.Ct. 367, 369, 92 L.Ed. 436. See, e. g., Chimel v. California, supra (search of arrested suspect and area within his control for weapons or evidence); Warden v. Hayden, 387 U.S. 294, 298-300, 87 S.Ct. 1642, 18 L.Ed.2d 782 ("hot pursuit" of fleeting suspect); Schmerber v. California, 384 U.S. 757, 770-771, 86 S.Ct. 1826, 1835-1836, 16 L.Ed.2d 908 (imminent destruction of evidence); see also supra, at 392-393.

Except for the fact that the offense under investigation was a homicide, there were no exigent circumstances in this case, as, indeed, the Arizona Supreme Court recognized. 115 Ariz., at 482, 566 P.2d, at 283. There was no indication that evidence would be lost, destroyed, or removed during the time required to obtain a search warrant. Indeed, the police guard at the apartment minimized that possibility. And there is no suggestion that a search warrant could not easily and conveniently have been obtained. We decline to hold that the seriousness of the offense under investigation itself creates exigent circumstances of the kind that under the Fourth Amendment justify a warrantless search.

Finally, the State argues that the "murder scene exception" is constitutionally permissible because it is narrowly confined by the guidelines set forth in the decision of the Arizona Supreme Court, see supra, at 389-390.8 In light of the extensive search that took place in this case it may be questioned what protection the guidelines afford a person in whose home a homicide or assault occurs. Indeed, these so-called guidelines are hardly so rigidly confining as the State seems to assert. They confer unbridled discretion upon the individual officer to interpret such terms as "reasonable . . . search," "serious personal injury with likelihood of death where there is reason to suspect foul play," and "reasonable period." It is precisely this kind of judgmental assessment of the reasonableness and scope of a proposed search that the Fourth Amendment requires be made by a neutral and objective magistrate, not a police officer. See, e. g., United States v. United States District Court, 407 U.S. 297, 316, 92 S.Ct. 2125, 2136, 32 L.Ed.2d 752; Coolidge v. New Hampshire, supra, at 449-453, 91 S.Ct., at 2029-2031; Mancusi v. DeForte, 392 U.S. 364, 371, 88 S.Ct. 2120, 2125, 20 L.Ed.2d 1154; Wong Sun v. United States, 371 U.S. 471, 481-482, 83 S.Ct. 407, 413-414, 9 L.Ed.2d 441.

It may well be that the circumstances described by the Arizona Supreme Court would usually be constitutionally sufficient to warrant a search of substantial scope. But the Fourth Amendment requires that this judgment in each case be made in the first instance by a neutral magistrate.

"The point of the Fourth Amendment, which often is not grasped by zealous officers, is not that it denies law enforcement the support of the usual inferences which reasonable men draw from evidence. Its protection consists in requiring that those inferences be drawn by a neutral and detached magistrate instead of being judged by the officer engaged in the often competitive enterprise of ferreting out crime." Johnson v. United States, supra, at 13-14, 68 S.Ct., at 369.

In sum, we hold that the "murder scene exception" created by the Arizona Supreme Court is inconsistent with the Fourth and Fourteenth Amendments—that the warrantless search of Mincey's apartment was not constitutionally permissible simply because a homicide had recently occurred there.9

Since there will presumably be a new trial in this case,10 it is appropriate to consider also the petitioner's contention that statements he made from a hospital bed were involuntary, and therefore could not constitutionally be used against him at his trial.

Mincey was brought to the hospital after the shooting and taken immediately to the emergency room where he was examined and treated. He had sustained a wound in his hip, resulting in damage to the sciatic nerve and partial paralysis of his right leg. Tubes were inserted into his throat to help him breathe, and through his nose into his stomach to keep him from vomiting; a catheter was inserted into his bladder. He received various drugs, and a device was attached to his arm so that he could be fed intravenously. He was then taken to the intensive care unit.

At about eight o'clock that evening, Detective Hust of the Tucson Police Department came to the intensive care unit to interrogate him. Mincey was unable to talk because of the tube in his mouth, and so he responded to Detective Hust's questions by writing answers on pieces of paper provided by the hospital.11 Hust told Mincey he was under arrest for the murder of a police officer, gave him the warnings required by Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694, and began to ask questions about the events that had taken place in Mincey's apartment a few hours earlier. Although Mincey asked repeatedly that the interrogation stop until he could get a lawyer, Hust continued to question him until almost midnight.

After a pretrial hearing, see Jackson v. Denno, 378 U.S. 368, 84 S.Ct. 1774, 12 L.Ed.2d 908, the trial court found that Mincey had responded to this interrogation voluntarily.12 When Mincey took the witness stand at his trial his statements in response to Detective Hust's questions were used in an effort to impeach his testimony in several respects.13 On appeal, the Arizona Supreme Court indicated its belief that because Detective Hust had failed to honor Mincey's request for a lawyer, the statements would have been inadmissible as part of the prosecution's case in chief. Miranda v. Arizona, supra. But relying on Harris v. New York, 401 U.S. 222, 91 S.Ct. 643, 28 L.Ed.2d 1, and Oregon v. Hass, 420 U.S. 714, 95 S.Ct. 1215, 43 L.Ed.2d 570, it held that since the trial court's finding of voluntariness was not "clear[ly] and manifest[ly]" erroneous the statements were properly used for purposes of impeachment. 115 Ariz., at 480, 566 P.2d, at 281.

Statements made by a defendant in circumstances violating the strictures of Miranda v. Arizona, supra, are admissible for impeachment if their "trustworthiness . . . satisfies legal standards." Harris v. New York, supra, 401 U.S., at 224, 91 S.Ct., at 645; Oregon v. Hass, supra, 420 U.S., at 722, 95 S.Ct., at 1220. But any criminal trial use against a defendant of his involuntary statement is a denial of due process of law, "even though there is ample evidence aside from the confession to support the conviction." Jackson v. Denno, 378 U.S. supra, at 376, 84 S.Ct., at 1780; Haynes v. Washington, 373 U.S. 503, 518, 83 S.Ct. 1336, 1345, 10 L.Ed.2d 513; Lynumn v. Illinois, 372 U.S. 528, 537, 83 S.Ct. 917, 922, 9 L.Ed.2d 922; Stroble v. California, 343 U.S. 181, 190, 72 S.Ct. 599, 603, 96 L.Ed. 872; see Chapman v. California, 386 U.S. 18, 23 and n. 8, 87 S.Ct. 824, 828, 17 L.Ed.2d 705. If therefore, Mincey's statements to Detective Hust were not " 'the product of a rational intellect and a free will ,' " Townsend v. Sain, 372 U.S. 293, 307, 83 S.Ct. 745, 754, 9 L.Ed.2d 770, quoting Blackburn v. Alabama, 361 U.S. 199, 208, 80 S.Ct. 274, 280, 4 L.Ed.2d 242, his conviction cannot stand. In making this critical determination, we are not bound by the Arizona Supreme Court's holding that the statements were voluntary. Instead, this Court is under a duty to make an independent evaluation of the record. Davis v. North Carolina, 384 U.S. 737, 741-742, 86 S.Ct. 1761, 1764, 16 L.Ed.2d 895; Haynes v. Washington, supra, at 515-516, 83 S.Ct., at 1345.

It is hard to imagine a situation less conducive to the exercise of "a rational intellect and a free will" than Mincey's. He had been seriously wounded just a few hours earlier, and had arrived at the hospital "depressed almost to the point of coma," according to his attending physician. Although he had received some treatment, his condition at the time of Hust's interrogation was still sufficiently serious that he was in the intensive care unit.14 He complained to Hust that the pain in his leg was "unbearable." He was evidently confused and unable to think clearly about either the events of that afternoon or the circumstances of his interrogation, since some of his written answers were on their face not entirely coherent.15 Finally, while Mincey was being questioned he was lying on his back on a hospital bed, encumbered by tubes, needles, and breathing apparatus. He was, in short, "at the complete mercy" of Detective Hust, unable to escape or resist the thrust of Hust's interrogation. Cf. Beecher v. Alabama, 389 U.S. 35, 38, 88 S.Ct. 89, 191, 19 L.Ed.2d 35.

In this debilitated and helpless condition, Mincey clearly expressed his wish not to be interrogated. As soon as Hust's questions turned to the details of the afternoon's events, Mincey wrote: "This is all I can say without a lawyer." Hust nonetheless continued to question him, and a nurse who was present suggested it would be best if Mincey answered. Mincey gave unresponsive or uninformative answers to several more questions, and then said again that he did not want to talk without a lawyer. Hust ignored that request and another made immediately thereafter.16 Indeed, throughout the interrogation Mincey vainly asked Hust to desist. Moreover, he complained several times that he was confused or unable to think clearly, or that he could answer more accurately the next day.17 But despite Mincey's entreaties to be let alone, Hust ceased the interrogation only during intervals when Mincey lost consciousness or received medical treatment, and after each such interruption returned relentlessly to his task. The statements at issue were thus the result of virtually continuous questioning of a seriously and painfully wounded man on the edge of consciousness.

There were not present in this case some of the gross abuses that have led the Court in other cases to find confessions involuntary, such as beatings, see Brown v. Mississippi, 297 U.S. 278, 56 S.Ct. 461, 80 L.Ed. 682, or "truth serums," see Townsend v. Sain, 372 U.S. 293, 83 S.Ct. 745, 9 L.Ed.2d 770. But "the blood of the accused is not the only hallmark of an unconstitutional inquisition." Blackburn v. Alabama, 361 U.S., at 206, 80 S.Ct., at 279. Determination of whether a statement is involuntary "requires more than a mere color-matching of cases." Reck v. Pate, 367 U.S. 433, 442, 81 S.Ct. 1541, 1547, 6 L.Ed.2d 948. It requires careful evaluation of all the circumstances of the interrogation.18

It is apparent from the record in this case that Mincey's statements were not "the product of his free and rational choice." Greenwald v. Wisconsin, 390 U.S. 519, 521, 88 S.Ct. 1152, 1154, 20 L.Ed.2d 77. To the contrary, the undisputed evidence makes clear that Mincey wanted not to answer Detective Hust. But Mincey was weakened by pain and shock, isolated from family, friends, and legal counsel, and barely conscious, and his will was simply overborne. Due process of law requires that statements obtained as these were cannot be used in any way against a defendant at his trial.

For the foregoing reasons, the judgment of the Arizona Supreme Court is reversed, and the case is remanded for further proceedings not inconsistent with this opinion.

It is so ordered.

Mr. Justice MARSHALL, with whom Mr. Justice BRENNAN joins, concurring.

I join the opinion of the Court, which holds that petitioner's rights under the Fourth and Fourteenth Amendments have been violated. I write today to emphasize a point that is illustrated by the instant case, but that applies more generally to all cases in which we are asked to review Fourth Amendment issues arising out of state criminal convictions.

It is far from clear that we would have granted certiorari solely to resolve the involuntary-statement issue in this case, for that could have been resolved on federal habeas corpus. With regard to the Fourth Amendment issue, however, we had little choice but to grant review, because our decision in Stone v. Powell, 428 U.S. 465, 96 S.Ct. 3037, 49 L. d.2d 1067 (1976), precludes federal habeas consideration of such issues. In Stone the Court held that, "where the State has provided an opportunity for full and fair litigation of a Fourth Amendment claim, a state prisoner may not be granted federal habeas corpus relief on the ground that evidence obtained in an unconstitutional search or seizure was introduced at his trial." Id., at 494, 96 S.Ct., at 3052 (footnotes omitted). Because of this holding, petitioner would not have been able to present to a federal habeas court the Fourth Amendment claim that the Court today unanimously upholds.

The additional responsibilities placed on this Court in the wake of Stone become apparent upon examination of decisions of the Arizona Supreme Court on the Fourth Amendment issue presented here. The Arizona court created its "murder-scene exception" in a 1971 case. State v. Sample, 107 Ariz. 407, 409-410, 489 P.2d 44, 46-47. A year later, when the defendant in that case sought federal habeas corpus relief, the United States Court of Appeals for the Ninth Circuit ruled, as we do today, that the exception could not be upheld under the Fourth Amendment. Sample v. Eyman, 469 F.2d 819, 821-822 (1972). When the Arizona Supreme Court next gave plenary consideration to the issue, prior to our decision in Stone, it apparently felt bound by the Ninth Circuit's Sample decision, although it found the case before it to be distinguishable. State v. Duke, 110 Ariz. 320, 324, 518 P.2d 570, 574 (1974).1

When the Arizona Supreme Court rendered its decision in the instant case, however, it took a different approach. The decision, issued nearly a year after Stone, merely noted that the Ninth Circuit had "disagreed" with the Arizona court's view of the validity of the murder scene exception. 115 Ariz. 472, 482 n. 4, 566 P.2d 273, 283 n. 4 (1977). It thus created an effective "conflict" for us to resolve. Cf. this Court's Rule 19(1)(b). If certiorari had not been granted, we would have left standing a decision of the State's highest court on a question of federal constitutional law that had been resolved in a directly opposing way by the highest federal court having special responsibility for the State. Regardless of which court's view of the Constitution was the correct one, such nonuniformity on Fourth Amendment questions is obviously undesirable; it is as unfair to state prosecutors and judges—who must make difficult determinations regarding what evidence is subject to exclusion—as it is to state criminal defendants.

Prior to Stone v. Powell, there would have been no need to grant certiorari in a case such as this, since the federal habeas remedy would have been available to the defendant. Indeed, prior to Stone petitioner here probably would not even have had to utilize federal habeas, since the Arizona courts were at that earlier time more inclined to follow the federal constitutional pronouncements of the Ninth Circuit, as discussed above. But Stone eliminated the habeas remedy with regard to Fourth Amendment violations, thus allowing state-court rulings to diverge from lower federal-co rt rulings on these issues and placing a correspondingly greater burden on this Court to ensure uniform federal law in the Fourth Amendment area.

At the time of Stone my Brother BRENNAN wrote that "institutional constraints totally preclude any possibility that this Court can adequately oversee whether state courts have properly applied federal law." 428 U.S., at 526, 96 S.Ct., at 3067 (dissenting opinion); see id., at 534, 96 S.Ct., at 3071. Because of these constraints, we will often be faced with a Hobson's choice in cases of less than national significance that could formerly have been left to the lower federal courts: either to deny certiorari and thereby let stand divergent state and federal decisions with regard to Fourth Amendment rights; or to grant certiorari and thereby add to our calendar, which many believe is already overcrowded, cases that might better have been resolved elsewhere. In view of this problem and others,2 I hope that the Court will at some point reconsider the wisdom of Stone v. Powell.3

Mr. Justice REHNQUIST, concurring in part and dissenting in part.

Petitioner was indicted for murder, assault, and three counts of narcotics offenses. He was convicted on all charges. On appeal, the Supreme Court of Arizona reversed all but the narcotics convictions. 115 Ariz. 472, 566 P.2d 273 (1977). In his petition for certiorari, petitioner challenged the introduction of evidence material to his narcotics convictions that was seized during a lengthy warrantless search of his apartment. Petitioner also challenged on voluntariness grounds the introduction of various statements made to the police relating to the murder charge. We granted certiorari, 434 U.S. 902, 98 S.Ct. 295, 54 L.Ed.2d 188, and the Court today reverses the Supreme Court of Arizona on both issues. While I agree with the Court that the warrantless search was not justifiable on the grounds advanced by the Arizona Supreme Court, I dissent from the Court's holding that Mincey's statements were involuntary and thus inadmissible.

* I join Part I of the Court's opinion. As the Supreme Court of Arizona recognized, the four-day warrantless search of petitioner's apartment did not, on the facts developed at trial, "fit within [any] usual 'exigent circumstances' exception." 115 Ariz., at 482, 566 P.2d, at 283. Instead, the State of Arizona asks us to adopt a separate "murder scene" exception to the warrant requirement and the Court, for the reasons stated in its opinion, correctly rejects this invitation.

I write separately on this issue only to emphasize that the question of what, if any, evidence was seized under established Fourth Amendment standards is left open for the Arizona courts to resolve on remand. Ante, at 395 n. 9. Much of the evidence introduced by the State at trial was apparently removed from the apartment the same day as the shooting. App. 40. And the State's brief suggests that some evidence—for example, blood on the floor required immediate examination. Brief for Respondent 70-71. The question of what evidence would have been "lost, destroyed, or removed" if a warrant had been obtained, ante, at 394, otherwise required an immediate search, or was in plain view should be considered on remand by the Arizona courts.

In onsidering whether exigencies required the search for or seizure of particular evidence, the previous events within the apartment cannot be ignored. I agree with the Court that the police's entry to arrest Mincey, followed by the shooting and the search for victims, did not justify the later four-day search of the apartment. Ante, at 391-392. But the constitutionality of a particular search is a question of reasonableness and depends on "a balance between the public interest and the individual's right to personal security free from arbitrary interference by law officers." United States v. Brignoni-Ponce, 422 U.S. 873, 878, 95 S.Ct. 2574, 2579, 45 L.Ed.2d 607 (1975). See Terry v. Ohio, 392 U.S. 1, 19, 88 S.Ct. 1868, 1878, 20 L.Ed.2d 889 (1968). In Pennsylvania v. Mimms, 434 U.S. 106, 98 S.Ct. 330, 54 L.Ed.2d 331 (1977), we held that once a motor vehicle had been lawfully detained for a traffic violation, police officers could constitutionally order the driver out of the vehicle. In so holding, we emphasized that the challenged intrusion was "occasioned not by the initial stop of the vehicle, which was admittedly justified, but by the order to get out of the car. We think this additional intrusion can only be described as de minimis." Id., at 111, 98 S.Ct., at 333. Similarly, in the instant case, the prior intrusions occasioned by the shooting and the police's response thereto may legitimize a search under some exigencies that in tamer circumstances might not permit a search.

The Court in Part II of its opinion advises the Arizona courts on the admissibility of certain statements made by Mincey that are relevant only to the murder charge. Because Mincey's murder conviction was reversed by the Arizona Supreme Court, and it is not certain that there will be a retrial, I would not reach this issue. Since the Court addresses the issue, however, I must register my disagreement with its conclusion.

Before trial, Mincey moved to suppress as involuntary certain statements that he had made while confined in an intensive care unit some hours after the shooting. As the Court acknowledges, the trial court found " 'with unmistakable clarity' " that the statements were voluntary, ante, at 397 n. 12, and the Supreme Court of Arizona, unanimously affirmed. 115 Ariz., at 479-480, 566 P.2d, at 280-281. This Court now disagrees and holds that "Mincey's statements were not 'the product of his free and rational choice' " and therefore "cannot be used in any way against [him] at his trial." Ante, at 401, 402. Because I believe that the Court both has failed to accord the state-court finding the deference that the Court has always found such findings due and also misapplied our past precedents, I dissent.

As the Court notes, ante, at 398, past cases of this Court hold that a state-court finding as to voluntariness which is "not fairly supported by the record cannot be conclusive of federal rights." Townsend v. Sain, 372 U.S. 293, 316, 83 S.Ct. 745, 758, 9 L.Ed.2d 770 (1963) (emphasis added). Instead, these cases require the Court to "make an independent determination on the undisputed facts." Stroble v. California, 343 U.S. 181, 190, 72 S.Ct. 599, 603, 96 L.Ed. 872 (1952) (emphasis added); Malinski v. New York, 324 U.S. 401, 404, 65 S.Ct. 781, 783, 89 L.Ed. 1029 (1945). It is well established that, "for purposes of review in this Court, the determination of the trial judge or of the jury will ordinarily be taken to resolve evidentiary conflicts and may be entitled to some weight even with respect to the ultimate conclusion on the crucial issue of voluntariness." Haynes v. Washington, 373 U.S. 503, 515, 83 S.Ct. 1336, 1344, 10 L.Ed.2d 513 (1963). See Lisenba v. California, 314 U.S. 219, 238, 62 S.Ct. 280, 290, 86 L.Ed. 166 (1941); Blackburn v. Alabama, 361 U.S. 199, 205, and n. 5, 80 S.Ct. 274, 279, 4 L.Ed.2d 242 (1960). Such deference, particularly on the resolution of e identiary conflicts, "is particularly apposite because the trial judge and jury are closest to the trial scene and thus afforded the best opportunity to evaluate contradictory testimony." Haynes, supra, at 516, 83 S.Ct., at 1344.

The Court in this case, however, ignores entirely some evidence of voluntariness and distinguishes away yet other testimony. There can be no discounting that Mincey was seriously wounded and laden down with medical equipment. Mincey was certainly not able to move about and, because of the breathing tube in his mouth, had to answer Detective Hust's questions on paper. But the trial court was certainly not required to find, as the Court would imply, that Mincey was "a seriously and painfully wounded man on the edge of consciousness." Ante, at 401. Nor is it accurate to conclude that Detective Hust "ceased the interrogation only during intervals when Mincey lost consciousness or received medical treatment, and after each such interruption returned relentlessly to his task." Ibid.

As the Arizona Supreme Court observed in affirming the trial court's finding of voluntariness, Mincey's nurse

"testified that she had not given [Mincey] any medication and that [he] was alert and able to understand the officer's questions. . . . She said that [Mincey] was in moderate pain but was very cooperative with everyone. The interrogating officer also testified that [Mincey] did not appear to be under the influence of drugs and that [his] answers were generally responsive to the questions." 115 Ariz., at 480, 566 P.2d at 281.

See App. 50-51 (testimony of Detective Hust), 63 and 66 (testimony of Nurse Graham).1 The uncontradicted testimony of Detective Hust also reveals a questioning that was far from "relentless." While the interviews took place over a three-hour time span, the interviews were not "very long; probably not more than an hour total for everything." Id., at 59. Hust would leave the room whenever Mincey received medical treatment "or if it looked like he was getting a little bit exhausted." Ibid. According to Detective Hust, Mincey never "los[t] consciousness at any time." Id., at 58.

As the Court openly concedes, there were in this case none of the "gross abuses that have led the Court in other cases to find confessions involuntary, such as beatings . . . or 'truth serums.' " Ante, at 401. Neither is this a case, however, where the defendant's will was "simply overborne" by "mental coercion." Cf. Blackburn v. Alabama, supra, 301 U.S., at 206, 80 S.Ct., at 279; Davis v. North Carolina, 384 U.S. 737, 741, 86 S.Ct. 1761, 1764, 16 L.Ed.2d 895 (1966); Greenwald v. Wisconsin, 390 U.S. 519, 521, 88 S.Ct. 1152, 1153, 20 L.Ed.2d 77 (1968). As the Supreme Court of Arizona observed, it was the testimony of both Detective Hust and Nurse Graham "that neither mental or physical force nor abuse was used on [Mincey]. . . . Nor were any promises made." 115 Ariz., at 480, 566 P.2d, at 281. See App. 58-59 (testimony of Detective Hust) and 63 (testimony of Nurse Graham). According to Mincey's own testimony, he wanted to help Hust "the best I could" and tried to answer each question "to the best of my r collection at the time that this was going on." Id., at 86. Mincey did not claim that he felt compelled by Detective Hust to answer the questions propounded.2 Cf. Greenwald, supra, 390 U.S., at 521, 88 S.Ct., at 1153.

By all of these standards enunciated in our previous cases, I think the Court today goes too far in substituting its own judgment for the judgment of a trial court and the highest court of a State, both of which decided these disputed issues differently than does this Court, and both of which were a good deal closer to the factual occurrences than is this Court. Admittedly we may not abdicate our duty to decide questions of constitutional law under the guise of wholly remitting to state courts the function of factfinding which is a necessary ingredient of the process of constitutional decision. But the authorities previously cited likewise counsel us against going to the other extreme, and attempting to extract from a cold record bits and pieces of evidence which we then treat as the "facts" of the case. I believe that the trial court was entitled to conclude that, notwithstanding Mincey's medical condition, his statements in the intensive care unit were admissible. The fact that the same court might have been equally entitled to reach the opposite conclusion does not justify this Court's adopting the opposite conclusion.

I therefore dissent from Part II of the Court's opinion.
