    OPINION OF THE COURT
    _______________________
    FUENTES, Circuit Judge.
    Pennsylvania inmate Daniel Jacobs was sentenced to
    death for murdering his girlfriend Tammy Mock and to life in
    prison for murdering their baby Holly Jacobs. On federal
    habeas review, the District Court concluded that Jacobs’ trial
    counsel rendered ineffective assistance during the penalty phase
    for failing to investigate and present mitigating evidence
    2
    concerning Jacobs’ cognitive and emotional impairments and his
    childhood and family background.          The District Court
    conditionally granted a writ of habeas corpus to allow the
    Commonwealth to resentence Jacobs. The District Court
    rejected each of Jacobs’ remaining challenges to his convictions
    and sentences.
    Jacobs now appeals from the District Court’s denial of
    federal habeas relief on several of his claims challenging his
    convictions.1
    For the following reasons, we will reverse the District
    Court’s denial of habeas corpus relief on Jacobs’ claim that trial
    counsel rendered ineffective assistance during the guilt phase by
    failing to adequately investigate, prepare, and present mental
    health evidence in support of his diminished capacity defense.
    We will affirm the District Court’s denial of habeas corpus relief
    on each of Jacobs’ remaining claims.
    I.       BACKGROUND
    Daniel Jacobs and his girlfriend Tammy Mock lived in an
    apartment in York, Pennsylvania, with their seven-month-old
    daughter Holly Jacobs. In February 1992, York police received
    a telephone call from Jacobs’ mother, Delois Jacobs, in Virginia,
    who under a fictitious identity asked them to check on Tammy
    1

    Court’s decision to grant habeas corpus relief on Jacobs’ claim
    of ineffective assistance of counsel at the penalty phase.
    3
    and Holly. This telephone call prompted the police to check the
    apartment, where they found Tammy and Holly dead in the
    bathtub. Tammy had been stabbed more than 200 times. Holly
    died from drowning and had no stab wounds or evidence of
    trauma. The police tracked down Delois, who gave a statement
    that Jacobs had admitted in telephone conversations that he had
    killed both Tammy and Holly. Delois also testified at a
    preliminary hearing that Jacobs admitted killing Tammy and
    Holly.
    In preparation for trial, counsel consulted with Dr. Robert
    Davis, a psychiatrist with a clinical and forensic practice. Dr.
    Davis conducted a mental health evaluation of Jacobs regarding
    his criminal responsibility and competency to stand trial.
    Counsel did not inform Dr. Davis that Jacobs was subject to the
    death penalty, and did not provide him with materials
    concerning Jacobs’ background or the background of the
    offenses. Dr. Davis reported orally to counsel that he found no
    evidence of a major mental illness. At counsel’s request, Dr.
    Davis did not prepare a written report.
    Jacobs was tried before a jury in the York County Court
    of Common Pleas for the first degree murders of Tammy and
    Holly. At trial, Jacobs denied killing Holly. He testified that
    Tammy killed Holly and that he stabbed Tammy to death after
    losing control at the sight of Holly dead in the bathtub. He
    presented a heat of passion and diminished capacity defense,
    i.e., that he was incapable of forming a specific intent to kill her
    given his mental state at the time of the killing. Delois testified
    that Jacobs admitted in his telephone calls that he killed Tammy,
    but that she could not remember whether he also admitted that
    4
    he killed Holly. The Commonwealth presented Delois’ pretrial
    statements that Jacobs admitted to killing both Tammy and
    Holly.
    The jury found Jacobs guilty of murder in the first degree
    of both Tammy and Holly. Jacobs was sentenced to death for
    murdering Tammy and to life in prison for murdering Holly. On
    direct appeal, the Pennsylvania Supreme Court affirmed the
    judgments of sentence. Commonwealth v. Jacobs, 
    639 A.2d 786
    (Pa. 1994) (“Jacobs I”). Jacobs pursued state collateral relief
    under Pennsylvania’s Post Conviction Relief Act (“PCRA”).
    The PCRA court conducted hearings and denied all relief in an
    oral decision rendered June 13, 1997. The Pennsylvania
    Supreme Court affirmed. Commonwealth v. Jacobs, 
    727 A.2d 545
    (Pa. 1999) (“Jacobs II”).
    Jacobs then filed the current habeas corpus petition in the
    District Court, in which he presented fifteen claims for relief. 2
    Without conducting an evidentiary hearing, the District Court
    granted habeas relief as to Jacobs’ claim of ineffective
    assistance of counsel during the penalty phase for failing to
    investigate and present mitigating evidence concerning Jacobs’
    cognitive and emotional impairments, and evidence that he
    suffers from the effects of a traumatic and neglectful childhood.
    2
    The District Court’s opinion enumerates the claims Jacobs
    presented in his habeas corpus petition. See Jacobs v. Horn, 
    129 F. Supp. 2d 390
    , 396-97 (M.D. Pa. 2001). Jacobs challenges the
    District Court’s denial of only four of those claims in this
    appeal, as set forth fully infra.
    5
    Jacobs v. Horn, 
    129 F. Supp. 2d 390
    , 405-08 (M.D. Pa. 2001)
    (“Jacobs III”). According to the District Court, if counsel had
    investigated Jacobs’ background and childhood, he would have
    discovered the following facts. Jacobs’ mother Delois drank
    heavily while she was pregnant with Jacobs. His alcoholic
    father severely beat her in the presence of their children. After
    Delois left Jacobs’ father when Jacobs was very young, she was
    involved in relationships with several men who drank heavily
    and abused her, as well as Jacobs. Jacobs’ older brother also
    beat him constantly and stabbed him on one occasion. When he
    was about six years old, Jacobs suffered brain damage due to a
    car accident. As a young teenager, Jacobs often acted like a
    child and required his mother’s assistance in getting dressed.
    Relatives who visited the home sometimes found Jacobs sitting
    at home undressed, dirty, and unkempt. One of Delois’
    boyfriends, with whom she was involved for about ten years,
    would become intoxicated with Jacobs then fly into a rage and
    beat him. As Jacobs grew older, he attempted to assist his
    mother by working but was unable to find and maintain
    employment.
    Based on counsel’s failure to discover and present
    mitigating evidence3 at the penalty phase, the District Court
    conditionally granted the writ of habeas corpus to allow the
    3
    The District Court also relied on mental health evidence
    demonstrating that Jacobs suffers from mild mental retardation,
    organic brain damage, and other mental and emotional
    impairments. See Jacobs 
    III, 129 F. Supp. 2d at 402-03
    . We
    discuss this evidence in detail infra.

    Commonwealth to resentence Jacobs for murdering Tammy. 
    Id. at 423.
    The District Court found each of Jacobs’ remaining
    challenges to his convictions either lacking in merit or
    procedurally barred from federal habeas review. Jacobs timely
    appealed. The District Court issued a certificate of appealability
    and stayed its order pending appeal.
    II.    JURISDICTION AND STANDARDS OF REVIEW
    Our jurisdiction is based on 28 U.S.C. §§ 1291 and 2253.
    The District Court had jurisdiction pursuant to 28 U.S.C.
    §§ 2241 and 2254. Because the District Court ruled on Jacobs’
    habeas corpus petition without conducting an evidentiary
    hearing, our review of the District Court’s decision is plenary.
    See Marshall v. Hendricks, 
    307 F.3d 36
    , 50 (3d Cir. 2002).
    We apply the same standards as the District Court, as
    mandated by the Antiterrorism and Effective Death Penalty Act
    of 1996 (“AEDPA”):
    An application for a writ of habeas corpus on
    behalf of a person in custody pursuant to the judgment of
    a State court shall not be granted with respect to any
    claim that was adjudicated on the merits in State court
    proceedings unless the adjudication of the claim—
    (1) resulted in a decision that was contrary to, or
    involved an unreasonable application of, clearly
    established Federal law, as determined by the
    7
    Supreme Court of the United States; or
    (2) resulted in a decision that was based on an
    unreasonable determination of the facts in light of
    the evidence presented in the State court
    proceeding.
    28 U.S.C. § 2254(d); 
    Marshall, 307 F.3d at 50
    . A federal habeas
    court must presume that a state court’s findings of fact are
    correct. See 28 U.S.C. § 2254(e)(1). The petitioner bears the
    burden of rebutting the presumption of correctness by clear and
    convincing evidence. 
    Id. A state
    court decision is contrary to Supreme Court
    precedent under § 2254(d)(1) where the state court reached a
    “‘conclusion opposite to that reached by [the Supreme] Court on
    a question of law or if the state court decides a case differently
    than [the Supreme] Court has on a set of materially
    indistinguishable facts.’” 
    Marshall, 307 F.3d at 51
    (quoting
    Williams v. Taylor, 
    529 U.S. 362
    , 413 (2000)). A state court
    decision is an unreasonable application under § 2254(d)(1) if the
    court “identifies the correct governing legal rule from the
    Supreme Court’s cases but unreasonably applies it to the facts
    of the particular case or if the state court either unreasonably
    extends a legal principle from the Supreme Court’s precedent to
    a new context where it should not apply or unreasonably refuses
    to extend that principle to a new context where it should apply.”
    8
    Gattis v. Snyder, 
    278 F.3d 222
    , 228 (3d Cir. 2002) (citing
    
    Williams, 529 U.S. at 407
    ). The unreasonable application test
    is an objective one – a federal court may not grant habeas relief
    merely because it concludes that the state court applied federal
    law erroneously or incorrectly. Wiggins v. Smith, 
    539 U.S. 510
    ,
    520-21 (2003); 
    Gattis, 278 F.3d at 228
    .
    AEDPA’s deferential standards of review do not apply
    “unless it is clear from the face of the state court decision that
    the merits of the petitioner’s constitutional claims were
    examined in light of federal law as established by the Supreme
    Court of the United States.” Everett v. Beard, 
    290 F.3d 500
    ,
    508 (3d Cir. 2002). In cases where the AEDPA standards of
    review do not apply, federal habeas courts apply pre-AEDPA
    standards of review. 
    Id. Prior to
    AEDPA, federal habeas courts
    conducted a de novo review over pure legal questions and mixed
    questions of law and fact. Appel v. Horn, 
    250 F.3d 203
    , 210 (3d
    Cir. 2001). In such circumstances, the state court’s factual
    determinations are still presumed to be correct, rebuttable upon
    a showing of clear and convincing evidence under § 2254(e)(1).
    
    Id. III. DISCUSSION
    On appeal, Jacobs challenges the District Court’s denial
    of habeas corpus relief on the following claims:4
    4
    The District Court issued a certificate of appealability
    authorizing Jacobs to pursue seven specific issues on appeal.
    See 28 U.S.C. § 2253(c)(3). Jacobs has elected to pursue only

    (1)    Trial counsel was ineffective for failing to
    adequately investigate, prepare, and present
    mental health evidence in support of the
    diminished capacity defense to the charges of first
    degree murder.
    (2)    Appellant’s constitutional rights to due process
    and the effective assistance of counsel were
    violated where the trial court failed to properly
    instruct the jury on Pennsylvania’s corpus delicti
    rule, trial counsel failed to object or request an
    appropriate instruction , and w here th e
    Commonwealth’s evidence was insufficient,
    under Pennsylvania law, to prove that Holly
    Jacobs was killed by criminal means.
    (3)    Appellant was denied his right to effective
    assistance of counsel as a result of trial counsel’s
    failure to investigate and present evidence that

    alcoholism and was intoxicated when the
    purported admissions were made.
    four of them on appeal.
    10
    (4)    Trial counsel was ineffective for failing to inquire
    concerning racial bias among members of the
    jury, where the entire venire was white and the
    case involved the murder of a white female
    teenager and child by her African-American
    boyfriend.
    Appellant’s Opening Br. at ii-iv.      We address each claim
    separately.
    A.     Ineffective Assistance of Counsel During the
    Guilt Phase for Failing to Investigate and
    Discover Mental Health Evidence
    We begin with Jacobs’ claim that trial counsel rendered
    ineffective assistance during the guilt phase by failing to
    investigate and present mental health evidence for the purpose
    of supporting his diminished capacity defense.5 Jacobs testified
    that on the day of the killings, he and Tammy argued, fought,
    and cut each other. According to Jacobs, after fighting with
    Tammy, he helped her into the bathtub, brought the baby into
    the bathroom, then left the bathroom. When he returned to the
    5
    Jacobs exhausted this claim by presenting it in his PCRA
    petition and on PCRA appeal. The Pennsylvania Supreme Court
    rejected this claim on the merits. See Jacobs 
    II, 727 A.2d at 548-49
    . Therefore we apply the AEDPA standard of review to
    this claim.
    11
    bathroom a short time later, he saw the baby dead in the bathtub,
    lost control, and stabbed Tammy repeatedly. Based on Jacobs’
    testimony, defense counsel presented a heat of passion and
    diminished capacity defense, asserting that Jacobs lacked the
    specific intent to kill Tammy Mock.6
    In preparation for Jacobs’ PCRA appeal, Dr. Julie Kessel,
    a licensed and certified psychiatrist familiar with forensic
    mental health issues, conducted a forensic psychiatric evaluation
    of Jacobs. (Kessel Affidavit ¶¶ 1-2). Dr. Kessel reported that
    Jacobs suffers from a number of mental health deficits,
    including mild mental retardation, organic brain damage, and
    schizoid personality disorder, and was a child witness and victim
    of abuse, neglect, and drug and alcohol abuse. (Id. ¶¶ 3-5).
    According to Dr. Kessel, the combination of these impairments
    substantially hindered Jacobs’ mental, emotional, and cognitive
    capacities. (Id. ¶ 5). In Dr. Kessel’s opinion, at the time of the
    crimes, Jacobs’ capacity to appreciate the criminality of his
    conduct and to conform his conduct to the requirements of the
    law was substantially impaired. (Id. ¶ 12). His impairments
    also substantially diminished his capacity to formulate the
    specific intent to kill. (Id. ¶ 14). Dr. Kessel concluded that
    Jacobs “did not in fact have the specific intent to kill Ms.
    6
    In Pennsylvania, the diminished capacity defense requires a
    defendant to admit general culpability. See Commonwealth v.
    Legg, 
    711 A.2d 430
    , 433 (Pa. 1998). Because Jacobs denied
    killing Holly, the diminished capacity defense was unavailable
    as to the baby’s murder. See Commonwealth v. Johnson, 
    815 A.2d 563
    , 578 (Pa. 2002).
    12
    Mock.” (Id. ¶ 14).
    Dr. Patricia Fleming, a licensed clinical psychologist and
    neuropsychologist, also evaluated Jacobs and reported that he
    “is seriously psychologically, emotionally and cognitively
    impaired.” (Fleming Affidavit ¶ 4). After conducting a number
    of psychological and neuropsychological tests, Dr. Fleming
    reported that Jacobs suffers from mild mental retardation, brain
    damage, and cognitive and emotional impairments. (Id. ¶¶ 9,
    13). At the time of the offenses, Dr. Fleming stated, Jacobs’
    disturbances “substantially impaired [his] capacity to appreciate
    the consequences of his conduct or to conform his conduct to
    the requirements of the law.” (Id. ¶ 13). In particular, his
    “mental retardation, brain damage and other mental health and
    cognitive impairments significantly diminish[ed] his capacity to
    premeditate and form a specific intent to kill.” (Id. ¶ 14). Dr.
    Fleming concluded that the facts “support the conclusion that
    [Jacobs] did not have the capacity to form the specific intent to
    kill.” (Id.).
    As described previously, trial counsel pursued a heat of
    passion and diminished capacity defense to the murder of
    Tammy Mock. Beyond his oral consultation with Dr. Davis,
    however, counsel took no further steps to discover evidence of
    Jacobs’ mental retardation, brain damage, or other impairments.
    Trial counsel was thus unable to support Jacobs’ diminished
    capacity defense with psychiatric evidence establishing that he
    suffered from any mental disorders which prevented him from
    formulating the specific intent to kill. Apparently the only
    evidence of heat of passion or diminished capacity presented at
    the guilt phase was Jacobs’ own testimony that he “lost it” and
    13
    stabbed Tammy repeatedly upon seeing their baby drowned in
    the bathtub. Jacobs claims that trial counsel’s failure to
    investigate, discover, and present mental health evidence
    constitutes ineffective assistance in violation of the Sixth
    Amendment.
    Sixth Amendment claims of ineffective assistance of
    counsel are governed by the familiar two-prong test of
    Strickland v. Washington, 
    466 U.S. 668
    (1984):
    First, the defendant must show that counsel’s
    performance was deficient. This requires showing that
    counsel made errors so serious that counsel was not
    functioning as the “counsel” guaranteed the defendant by
    the Sixth Amendment. Second, the defendant must show
    that the deficient performance prejudiced the defense.
    This requires showing that counsel’s errors were so
    serious as to deprive the defendant of a fair trial, a trial
    whose result is reliable.
    
    Id. at 687;
    see 
    Williams, 529 U.S. at 390-91
    .
    Under Strickland’s first prong, Jacobs must show that
    counsel’s performance was deficient. The proper standard for
    attorney performance is that of “reasonably effective assistance”
    – Jacobs must show that trial counsel’s representation fell below
    an objective standard of reasonableness considering all the
    circumstances. 
    Strickland, 466 U.S. at 687-88
    . Counsel’s
    reasonableness must be assessed on the facts of the particular
    case, viewed as of the time of counsel’s conduct. 
    Id. at 689.
    In
    the context of ineffective assistance based on counsel’s failure
    14
    to investigate, the court must determine whether counsel
    exercised “reasonable professional judgment.” 
    Wiggins, 539 U.S. at 522-23
    .
    In Pennsylvania, when asserting a diminished capacity
    defense, “a defendant attempts to negate the element of specific
    intent to kill and, if successful, first degree murder is reduced to
    third degree murder.” Commonwealth v. McCullum, 
    738 A.2d 1007
    , 1009 (Pa. 1999). According to the Pennsylvania Supreme
    Court, “[d]iminished capacity is an extremely limited defense,
    which requires extensive psychiatric testimony establishing a
    defendant suffered from one or more mental disorders which
    prevented him from formulating the specific intent to kill.”
    Commonwealth v. Cuevas, 
    832 A.2d 388
    , 393 (Pa. 2003) (citing
    Commonwealth v. Zettlemoyer, 
    454 A.2d 937
    , 943 (Pa. 1982)).
    The specific question posed here is whether counsel
    exercised reasonable professional judgment in failing to
    investigate further and discover Jacobs’ mental retardation,
    brain damage, and other impairments as evidence to support the
    diminished capacity defense. To his credit, counsel did ask Dr.
    Davis to evaluate Jacobs. (Davis Affidavit ¶ 2). Counsel did
    not, however, inform Dr. Davis that the Commonwealth was
    seeking the death penalty, nor did he provide Davis with any
    background information concerning the crimes or Jacobs’
    history. (Id. ¶¶ 2, 3). According to Dr. Davis, if he had known
    that this was a capital case, he would have automatically
    requested testing for brain damage or other impairments that are
    not readily apparent from a standard evaluation. (Id. ¶ 6). Dr.
    Davis reported orally to counsel that he did not find any
    evidence of a major mental illness. (Id. ¶ 4). Upon receipt of
    15
    this report, counsel chose not to investigate further, although he
    presented the diminished capacity defense at trial. Counsel did
    not question any of Jacobs’ family members or friends regarding
    his childhood, background, or mental health history, or obtain
    any medical records demonstrating mental deficiencies.
    At the time counsel decided not to investigate further, he
    knew or should have known from Jacobs’ behavior and from his
    interactions with Jacobs that he should initiate some
    investigation “of a psychological or psychiatric nature.” (PCRA
    Hearing Tr. 5/29/97 at 29:24). Counsel knew that Jacobs, a
    young man with no criminal history or history of violence,
    admitted to stabbing his girlfriend more than 200 times.
    Counsel knew that Jacobs faced the death penalty, yet did not
    inform Dr. Davis that the Commonwealth was seeking the death
    penalty, nor did he provide Davis with any background
    information concerning the crimes or Jacobs’ history. Counsel
    interviewed Jacobs’ mother before trial, but did not ask her any
    questions regarding Jacobs’ mental health history, childhood, or
    background. In light of all that was known or made available to
    counsel, we conclude that Jacobs has satisfied the first prong of
    the Strickland test. He has demonstrated that counsel did not
    exercise reasonable professional judgment in failing to
    investigate further and discover evidence of Jacobs’ mental
    retardation, brain damage, and other impairments that could
    have prevented him from forming the specific intent to kill
    Tammy Mock.
    The District Court was persuaded that counsel’s
    performance was not deficient in this regard. See Jacobs 
    III, 129 F. Supp. 2d at 412-13
    . The District Court relied on two
    16
    cases from other circuits that the District Court interpreted as
    holding that counsel is not required to investigate further unless
    a psychiatric evaluator indicates further information is needed.
    
    Id. One of
    these, on which the Commonwealth relies heavily,
    is Hendricks v. Calderon, 
    70 F.3d 1032
    (9th Cir. 1995).
    In Hendricks, counsel hired a psychiatrist who met with
    the defendant for about four and one-half hours and found no
    evidence to support a “mental defense.” 
    Id. at 1037.
    The
    psychiatrist posited that psychological testing might be useful
    and suggested that counsel consult a psychologist.            A
    psychologist then interviewed the defendant for about fifteen
    hours, ran several psychological tests, reviewed records
    regarding the crime and the defendant’s life history, and found
    no evidence to support a mental defense. Counsel relied on the
    experts’ opinions and decided not to explore further or present
    a mental defense. 
    Id. The Ninth
    Circuit ruled that Hendricks’ attorneys had
    discharged their duty to seek out a psychiatric evaluation. 
    Id. at 1038-39.
    The Ninth Circuit further ruled that counsel “fell
    within the broad range of presumptively acceptable conduct by
    hiring two mental health professionals to investigate potential
    mental defenses and then relying on their shared, unqualified
    conclusion that there was no basis for a mental defense.” 
    Id. at 1039.
    Attorneys, the court opined, cannot be forced to “second-
    guess their experts.” 
    Id. Hendricks is
    dissimilar to Jacobs’ case in two significant
    respects. First, Hendricks involved material facts vastly
    different from those in Jacobs’ case. Hendricks’ attorneys
    17
    employed both a psychiatrist and a psychologist who evaluated
    the defendant separately and extensively, and with the benefit of
    background information. The experts agreed that no evidence
    existed to support a diminished capacity defense. In Jacobs’
    case, while counsel asked Dr. Davis to evaluate Jacobs, there is
    no information to indicate that Dr. Davis’ evaluation was
    sufficiently extensive. His affidavit states only that he
    “examined Mr. Jacobs to determine if he had a major mental
    illness or other impairment that would render him incompetent
    to stand trial or that would negate or reduce his criminal
    responsibility.” (Davis Affidavit ¶ 4). In conducting his
    evaluation, Dr. Davis was not aware that Jacobs was subject to
    the death penalty, nor was Dr. Davis privy to any background
    information whatsoever. As a result, no psychological testing
    occurred. In turn, counsel failed to discover Jacobs’ mental
    retardation, brain damage, and other emotional and mental
    impairments.
    We also find the legal issue presented in Hendricks
    unlike the one presented in Jacobs’ case. The question raised in
    Hendricks was whether counsel was ineffective in deciding not
    to investigate more extensively before making a strategic choice
    not to present a diminished capacity defense at all. The question
    raised here is whether counsel was ineffective by failing to
    investigate and discover evidence to support the defense he
    pursued. Although subtle, the distinction is significant. An
    attorney’s strategic choices made after a thorough investigation
    “are virtually unchallengeable.” 
    Strickland, 466 U.S. at 690-91
    .
    Hendricks reiterates and applies this well established principle.
    Counsel’s failure to investigate adequately and discover
    evidence to support his strategy of choice is an entirely different
    18
    question, one which Hendricks does not address. See 
    Wiggins, 539 U.S. at 523
    . In short, Hendricks is inapposite and does not
    affect our conclusion that Jacobs has satisfied the first prong of
    Strickland by demonstrating that his attorney failed to exercise
    reasonable professional judgment in this regard.7
    7
    Our dissenting colleague suggests that counsel performed
    reasonably by relying on Dr. Davis’ oral report in deciding not
    to inquire further into Jacobs’ mental health. The dissent
    correctly notes that Dr. Davis did not state that he was incapable
    of forming a conclusion on the information available to him, nor
    did he ask for any additional information. Several other “highly
    relevant facts” prevent us from agreeing, however. It is
    undisputed that Dr. Davis was completely unaware that Jacobs
    was subject to the death penalty. (Davis Affidavit ¶¶ 2, 4, 5, 7.)
    At the time he offered his opinion, Dr. Davis was unaware that
    Tammy Mock had been stabbed more than 200 times because he
    was not provided with the autopsy report or other background
    materials concerning the killings, other than “a police report
    with some information concerning the alleged facts of the
    offense.” (Id. ¶¶ 3, 12.) Dr. Davis was unaware that the killings
    occurred after a heated argument between Jacobs and Mock.
    (Id. ¶ 12.) He knew nothing about Jacobs’ background, such as
    his lack of a criminal history or history of violent behavior. (Id.
    ¶¶ 3, 12.) As Dr. Davis later opined, these facts alone “suggest
    that Mr. Jacobs was highly emotionally disturbed at the time of
    the offense,” and that he was “overcome by a powerful and
    uncharacteristic emotional reaction.” (Id. ¶ 12.) In our view, in
    light of all the circumstances present in this capital case, it was
    patently unreasonable for counsel to rely solely on Dr. Davis’
    19
    In addition to establishing that his attorney performed
    deficiently, Jacobs must demonstrate that he was prejudiced by
    counsel’s error. See 
    Strickland, 466 U.S. at 692
    . The prejudice
    component requires Jacobs to show “that there is a reasonable
    probability that, but for counsel’s unprofessional errors, the
    result of the proceeding would have been different.” 
    Id. at 694.
    Jacobs need not show that counsel’s deficient performance
    “more likely than not altered the outcome in the case” – rather,
    he must show only “a probability sufficient to undermine
    confidence in the outcome.” 
    Id. at 693-94.
    This standard is not
    “‘a stringent one.’” Jermyn v. Horn, 
    266 F.3d 257
    , 282 (3d Cir.
    2001) (quoting Baker v. Barbo, 
    177 F.3d 149
    , 154 (3d Cir.
    1999)).
    We are persuaded that Jacobs has satisfied Strickland’s
    prejudice prong. As described above, Dr. Kessel conducted a
    forensic psychiatric evaluation of Jacobs. (Kessel Affidavit ¶¶
    1-2). According to Dr. Kessel, the combination of Jacobs’
    mental health impairments substantially impaired Jacobs’
    mental, emotional, and cognitive capacities. (Id. ¶ 5). In Dr.
    Kessel’s opinion, Jacobs “did not in fact have the specific intent
    to kill” Tammy Mock. (Id. ¶ 14). Dr. Fleming also evaluated
    Jacobs and concluded that Jacobs’ disturbances “substantially
    uninformed opinion in deciding not to investigate Jacobs’
    mental health history further. The unreasonableness of
    counsel’s decision is compounded by the fact that he pursued a
    diminished capacity defense without any expert evidence to
    support it, as expressly required by Pennsylvania law. See
    
    Cuevas, 832 A.2d at 393
    .
    20
    impaired [his] capacity to appreciate the consequences of
    conduct or to conform his conduct to the requirements of the
    law.” (Fleming Affidavit ¶ 13). Dr. Fleming also stated that
    Jacobs’ “mental retardation, brain damage and other mental
    health and cognitive impairments significantly diminish[ed] his
    capacity to premeditate and form a specific intent to kill.” (Id.
    ¶ 14). According to Dr. Fleming, the facts “support the
    conclusion that he did not have the capacity to form the specific
    intent to kill.” (Id.).
    In Pennsylvania, diminished capacity “is an extremely
    limited defense, which requires extensive psychiatric testimony
    establishing a defendant suffered from one or more mental
    disorders which prevented him from formulating the specific
    intent to kill.” 
    Cuevas, 832 A.2d at 393
    . Both Drs. Kessel and
    Fleming have expressed a willingness to testify that Jacobs
    suffered from mental disorders that deprived him of the capacity
    to form the specific intent to kill Tammy Mock. In our view,
    Jacobs’ case is the specific type in which the diminished
    capacity defense as to the murder of Tammy Mock is
    appropriate. Moreover, we are persuaded that if the jury had
    heard Drs. Kessel and Fleming testify based on their extensive
    evaluations, there is a reasonable probability that the jury would
    have found Jacobs guilty of third degree murder, not first degree
    murder, of Tammy Mock. 8
    8
    We are aware, as our dissenting colleague notes, that no
    court heretofore has decided whether Jacobs has satisfied the
    prejudice prong of Strickland. Both the Pennsylvania Supreme
    Court and the District Court ruled that trial counsel did not
    21
    For these reasons, we conclude that Jacobs has
    demonstrated that trial counsel rendered ineffective assistance
    in violation of the Sixth Amendment. Under AEDPA, however,
    our determination that the Pennsylvania Supreme Court
    erroneously rejected this claim on the merits does not
    necessarily entitle Jacobs to federal habeas relief. Rather,
    AEDPA requires Jacobs to demonstrate that the Pennsylvania
    Supreme Court’s rejection of this claim either is contrary to, or
    involved an objectively unreasonable application of, Strickland.
    perform deficiently. Thus, neither of those courts was required
    to decide whether Jacobs suffered prejudice. Even so, the issue
    of prejudice was properly before each of those courts, as were
    the affidavits of Drs. Kessel and Fleming supporting Jacobs’
    assertion of prejudice. The Commonwealth could have
    challenged Jacobs’ expert evidence by submitting expert
    evidence of its own. It appears that the Commonwealth made
    the strategic choice not to submit such evidence, a choice we do
    not question. Regardless, because the prejudice determination
    here is purely a legal one, we need not remand to the District
    Court to make such a determination in the first instance or to
    allow the Commonwealth a second opportunity to challenge
    Jacobs’ expert evidence. We emphasize that Jacobs need not
    establish his diminished capacity defense conclusively for the
    purpose of demonstrating a Sixth Amendment violation. Rather,
    as we have explained, he is required to show only a reasonable
    probability that the outcome of the proceedings would have been
    different if trial counsel had presented evidence of Jacobs’
    mental retardation, organic brain damage, and other mental
    deficiencies. See 
    Strickland, 466 U.S. at 694
    .
    22
    See 28 U.S.C. § 2254(d)(1); 
    Wiggins, 539 U.S. at 520-21
    ;
    
    Gattis, 278 F.3d at 228
    .
    In denying this claim, the Pennsylvania Supreme Court
    did not cite Strickland, nor did it apply Strickland’s two-part
    test. Rather, the Pennsylvania Supreme Court applied the
    following standard:
    With respect to claims of ineffective assistance of trial
    counsel, Appellant is required to establish that the claim
    has arguable merit; that trial counsel had no reasonable
    basis for proceeding as he did; and that the alleged
    ineffectiveness of counsel so undermined the truth-
    determining process that no reliable adjudication of guilt
    or innocence could have taken place.
    Jacobs 
    II, 727 A.2d at 547-48
    (citing Commonwealth v. Collins,
    
    687 A.2d 1112
    , 1113 (Pa. 1996)). The Pennsylvania Supreme
    Court then concluded:
    Based on the results of the psychiatric evaluation, and
    given Appellant’s trial testimony, it is clear that trial
    counsel did investigate and pursue a diminished capacity
    defense on behalf of Appellant to the best of his ability.
    Accordingly, as trial counsel had a reasonable basis for
    proceeding as he did, he cannot be deemed ineffective.
    Jacobs 
    II, 727 A.2d at 549
    .
    The Pennsylvania Supreme Court’s rejection of this claim
    is based solely on the finding that counsel had a reasonable basis
    23
    for deciding not to investigate further. In making this finding,
    the Pennsylvania Supreme Court placed great weight on the fact
    that Dr. Davis orally reported that he found no evidence of a
    major mental illness negating or reducing criminal liability.
    Apparently, the Pennsylvania Supreme Court disregarded
    counsel’s failure to provide Dr. Davis with the necessary
    information to conduct a proper evaluation, as well as several
    other highly relevant facts known to counsel at the time he
    decided not to investigate further.
    In our view, the Pennsylvania Supreme Court’s decision,
    based on a single factor to the exclusion of other relevant
    factors, involved an unreasonable application of Strickland.9
    Strickland teaches that a court deciding any ineffectiveness
    claim must “determine whether, in light of all the circumstances,
    the identified acts or omissions [of counsel] were outside the
    wide range of professionally competent assistance.” 
    Strickland, 466 U.S. at 690
    (emphasis added). Specifically, in an
    ineffectiveness claim challenging counsel’s decision not to
    investigate, Strickland mandates that counsel’s decision “must
    be directly assessed for reasonableness in all the circumstances.”
    
    Id. at 691.
    9
    We have previously ruled that Pennsylvania’s test for
    assessing ineffective assistance of counsel claims is not contrary
    to Strickland. See Werts v. Vaughn, 
    228 F.3d 178
    , 204 (3d Cir.
    2000). Thus, under § 2254(d)(1), the relevant question here is
    whether the Pennsylvania Supreme Court’s decision involved an
    unreasonable application of Strickland.
    24
    Since Strickland, the United States Supreme Court has
    repeatedly emphasized the necessity of assessing an
    ineffectiveness claim in light of all the circumstances. See
    
    Wiggins, 539 U.S. at 533
    ; Roe v. Flores-Ortega, 
    528 U.S. 470
    ,
    478 (2000); Kimmelman v. Morrison, 
    477 U.S. 365
    , 384 (1986).
    We too have underscored the importance of the circumstance-
    specific inquiry mandated by Strickland. See Lewis v. Johnson,
    
    359 F.3d 646
    , 659 (3d Cir. 2004); Rompilla v. Horn, 
    355 F.3d 233
    , 257 (3d Cir.), cert. granted, 
    125 S. Ct. 27
    (2004); Duncan
    v. Morton, 
    256 F.3d 189
    , 201 (3d Cir. 2001); Berryman v.
    Morton, 
    100 F.3d 1089
    , 1101 (3d Cir. 1996); Frey v. Fulcomer,
    
    974 F.2d 348
    , 358 (3d Cir. 1992). These cases amply
    demonstrate that an assessment of the reasonableness of
    counsel’s performance under Strickland requires consideration
    of all the circumstances. Here, the Pennsylvania Supreme Court
    did not adhere to Strickland’s clear mandate. In light of all the
    relevant facts described above, we are constrained to conclude
    that the Pennsylvania Supreme Court’s decision involved an
    unreasonable application of Strickland.
    For these reasons, we conclude that trial counsel rendered
    ineffective assistance in violation of the Sixth Amendment at the
    guilt phase by failing to investigate and present evidence
    showing that Jacobs suffered from mental retardation, organic
    brain damage, and other emotional and mental impairments that
    prevented him from forming the specific intent to kill Tammy
    Mock. We further conclude that the Pennsylvania Supreme
    Court’s rejection of this claim on the merits involved an
    unreasonable application of Strickland. Accordingly, we will
    reverse the District Court’s decision denying federal habeas
    relief on this claim, and will remand with instructions to grant
    25
    the writ.10
    While our decision invalidates Jacobs’ conviction for the
    first degree murder of Tammy Mock, the question remains
    whether counsel’s ineffectiveness also invalidates Jacobs’
    conviction for murdering Holly. As noted previously, the
    diminished capacity defense requires a defendant to admit
    general culpability. See Commonwealth v. Legg, 
    711 A.2d 430
    ,
    433 (Pa. 1998). Because Jacobs denied killing Holly, the
    10
    Our decision is not influenced by Jacobs’ argument that the
    District Court’s decision denying habeas relief based on
    counsel’s conduct during the guilt phase is inconsistent with its
    grant of relief on his claim of ineffective assistance during the
    penalty phase. During the guilt phase, the defendant must
    establish that he “suffered from one or more mental disorders
    which prevented him from formulating the specific intent to
    kill.” See 
    Cuevas, 832 A.2d at 393
    . Diminished capacity
    evidence at the guilt phase is limited to expert psychiatric
    testimony demonstrating that the defendant was unable to form
    the specific intent to kill. See 
    McCullum, 738 A.2d at 1010
    .
    The jury’s function during the sentencing phase is to weigh
    mitigating factors against aggravating factors. See 42 Pa. Cons.
    Stat. Ann. § 9711(c). At sentencing, the jury must consider
    “evidence of mitigation concerning the character and record of
    the defendant and the circumstances of his offense” and must
    weigh mitigating factors against aggravating factors. 42 Pa.
    Cons. Stat. Ann. §§ 9711(c), (e)(8). In short, counsel’s duties at
    the guilt phase and his duties at the sentencing phase differ
    significantly.
    26
    diminished capacity defense was unavailable as to the baby’s
    murder. See Commonwealth v. Johnson, 
    815 A.2d 563
    , 578
    (Pa. 2002). That is because, as Jacobs acknowledges, a
    diminished capacity defense is inconsistent with an assertion of
    innocence.11 See Commonwealth v. Williams, 
    846 A.2d 105
    ,
    111 (Pa. 2004).
    Nonetheless, Jacobs argues that a diminished capacity
    defense to the murder of Holly would not be inconsistent in his
    case. Jacobs cites Legg for the proposition that “a diminished
    capacity defense is available where the defendant admits to facts
    which may cause a jury to hold him responsible for the killing
    to some degree.” (Appellant’s Supplemental Mem. at 2).
    Jacobs argues that because his trial counsel conceded in closing
    argument that Holly’s death could have been accidental and that
    the jury could have found Jacobs criminally responsible for her
    death, a diminished capacity defense would not have been
    inconsistent with his testimony that he did not kill Holly.
    To the extent that Jacobs argues that his case is similar to
    11
    See Appellant’s Supplemental M em. at 2. After oral
    argument, Jacobs’ counsel requested permission to file a
    supplemental memorandum addressing whether counsel’s
    ineffectiveness undermined Jacobs’ conviction for murdering
    Holly. The Commonwealth in turn requested permission to file
    a supplemental memorandum responding to Jacobs’
    supplemental memorandum. We granted these requests and
    have considered the parties’ supplemental memoranda in
    rendering our decision.
    27
    Legg, we disagree. There, Betty Legg was convicted of the first
    degree murder of her husband and was sentenced to life in
    prison. 
    Legg, 711 A.2d at 432
    . Legg expressly admitted that
    she shot and killed her husband but maintained that the shooting
    was accidental. 
    Id. at 435.
    Counsel did not present evidence of
    Legg’s diminished capacity. The Pennsylvania Supreme Court
    found that a diminished capacity defense would not have
    conflicted with Legg’s position that the shooting was accidental,
    and ruled that counsel rendered ineffective assistance by failing
    to present such evidence. 
    Id. at 435.
    Here, Jacobs has consistently denied killing Holly and in
    fact blamed her death on Tammy. Under Pennsylvania law, a
    diminished capacity defense was simply unavailable as to
    Holly’s death because Jacobs maintained his innocence. We
    find nothing in Legg suggesting otherwise. In fact, Legg
    distinguishes Betty Legg’s situation from others in which the
    defendants maintained their innocence. See 
    id. at 434-35
    (distinguishing Commonwealth v. Cross, 
    634 A.2d 173
    (Pa.
    1993), and Commonwealth v. Mizell, 
    425 A.2d 424
    (Pa. 1981)).
    Because the sole issue at trial was Betty Legg’s mental state at
    the time of the shooting, not whether she killed her husband,
    Legg’s counsel should have raised a diminished capacity
    defense to negate the specific intent to kill. See 
    Legg, 711 A.2d at 435
    .
    Moreover, we do not read defense counsel’s closing
    argument as a concession that Jacobs could be criminally
    responsible for Holly’s death.    Rather, defense counsel
    acknowledged that there was no direct evidence that Tammy
    Mock murdered Holly and stated that “we don’t know” how
    28
    Holly drowned. (Trial Tr., Vol. IV, 9/17/92 at 735:9-736:4).
    Regardless, counsel emphasized, Jacobs was “most sure” that he
    did not hurt Holly in any way and believed that Tammy Mock
    killed Holly. (Id. at 736:5-736:12, 739:1-739:4). Counsel
    concluded his closing argument by reminding the jury that
    Jacobs admitted causing Tammy Mock’s death but denied
    causing Holly’s death. (Id. at 745:20-746:4).
    Jacobs argues alternatively that counsel’s ineffective
    assistance invalidates his conviction for murdering Holly
    because expert testimony regarding his mental disorders and
    defects would have corroborated his testimony that he lashed out
    in a rage after finding Holly dead in the bathtub. This, he
    believes, would have supported his testimony that he did not kill
    Holly. Whether the evidence would have supported his version
    of the facts, however, is not the relevant inquiry. We must
    examine his argument in light of his specific claim that trial
    counsel rendered ineffective assistance by failing to present such
    evidence. Under Strickland, we must determine whether there
    is a reasonable probability that the result of the proceeding
    would have been different if the jury had heard expert testimony
    regarding his mental disorders. See 
    Strickland, 466 U.S. at 694
    .
    In light of Delois’ two statements that Jacobs admitted killing
    Holly, we cannot find a reasonable probability that the jury
    would have acquitted Jacobs of Holly’s murder if the jury had
    heard expert testimony regarding his mental disorders.
    For these reasons, we will reverse the District Court’s
    decision denying federal habeas relief as to Jacobs’ claim of
    ineffective assistance of counsel at the guilt phase in failing to
    investigate and present evidence of mental disorders, but only as
    29
    to Jacobs’ conviction for the first degree murder of Tammy
    Mock. We will remand to the District Court with instructions to
    grant the writ conditioned upon the Commonwealth providing
    Jacobs a new trial on the charge of murdering Tammy Mock.
    B.    Challenges to Jacobs’ Conviction for the
    Murder of Holly Jacobs Based on
    Pennsylvania’s Corpus Delicti Rule
    Jacobs’ next claim is based on Pennsylvania’s corpus
    delicti rule and its application to his mother’s pretrial statements
    that he admitted in telephone conversations that he killed his
    baby Holly. Jacobs alleges that the trial court violated his
    federal right to due process by failing to instruct the jury in
    accordance with state law on the Commonwealth’s burden of
    proof to establish the corpus delicti of Holly’s murder before
    considering his out-of-court admissions. He also alleges that
    counsel rendered ineffective assistance in violation of the Sixth
    Amendment by failing to object to the corpus delicti jury
    instruction. He further asserts that the evidence apart from his
    out-of-court admissions is insufficient to establish the corpus
    delicti.
    According to Pennsylvania’s corpus delicti rule,12 before
    introducing a criminal defendant’s out-of-court admission, “the
    Commonwealth must establish by independent evidence that a
    crime has in fact been committed.” Commonwealth v. Reyes,
    12
    Translated literally, corpus delicti means “the body of a
    crime.” Black’s Law Dictionary 344 (6th ed. 1990).
    30
    
    681 A.2d 724
    , 727 (Pa. 1996). A defendant’s confession “is not
    evidence in the absence of proof of the corpus delicti.”
    Commonwealth v. Taylor, 
    831 A.2d 587
    , 590 (Pa. 2002)
    (internal quotations omitted). In a murder prosecution, the
    corpus delicti consists of evidence that an individual is dead and
    that the death resulted from criminal means. Commonwealth v.
    Tallon, 
    387 A.2d 77
    , 80 (Pa. 1978).
    The Pennsylvania Supreme Court has described the
    application of the rule as a “two-tiered approach” having a “dual
    level of proof.” 
    Reyes, 681 A.2d at 728
    . The first tier pertains
    solely to the admissibility of the defendant’s out-of-court
    confession. 
    Id. at 727.
    At this stage, the trial court must
    determine whether the Commonwealth has established by a
    preponderance of the evidence (apart from the confession) that
    a crime has in fact been committed.13 
    Id. at 727-28.
    Once the
    trial court admits the confession, the jury may not consider the
    confession unless the Commonwealth proves the corpus delicti
    beyond a reasonable doubt. 
    Id. at 728;
    Tallon, 387 A.2d at 81
    .
    Because Jacobs’ claim actually consists of three related
    but separate claims, he must show that he exhausted each of
    13
    Jacobs makes clear that he does not challenge the
    admissibility of his out-of-court statements to his mother.
    (Reply Br. at 10-11).
    31
    them.14 In his PCRA petitions,15 Jacobs does not mention the
    corpus delicti rule at all. In his brief on PCRA appeal, however,
    Jacobs argues that the trial court misapplied the corpus delicti
    rule and wrongly admitted his out-of-court statements, that the
    trial court failed to instruct the jury properly on the corpus
    delicti rule, and that all previous counsel were ineffective for
    failing to object to the trial court’s actions and failing to pursue
    the matter on direct appeal or in PCRA proceedings.
    Apparently, the Pennsylvania Supreme Court overlooked
    Jacobs’ challenge based on the trial court’s corpus delicti
    instruction. Plainly, the Pennsylvania Supreme Court addressed
    the merits of Jacobs’ assertion that “trial counsel and PCRA
    counsel were ineffective in not raising the trial court’s failure to
    14
    Unfortunately, the Commonwealth does not address fully
    whether these claims are properly exhausted.                The
    Commonwealth reads these claims in part as challenging the
    trial court’s admission of Jacobs’ statements to his mother, and
    asserts that it is not cognizable as an issue of state law.
    (Appellees’ Br. at 28-29). The Commonwealth also reads these
    claims as challenging counsel’s failure to object to the
    admission of the evidence, and argues that it is exhausted but
    without merit because Jacobs’ statements were properly
    admitted. It appears that the Commonwealth concedes that
    Jacobs exhausted his challenge to the jury instruction on the
    corpus delicti rule.
    15
    Jacobs filed a pro se PCRA petition, which counsel
    subsequently supplemented.

    apply the corpus delicti rule regarding the death of Holly
    Jacobs.” Jacobs 
    II, 727 A.2d at 552
    . The Pennsylvania
    Supreme Court also addressed whether “the trial court erred in
    permitting into evidence the statements of [Jacobs’] mother
    relating to [his] confessed killing of Holly Jacobs where there
    was no independent evidence to establish that Holly Jacobs died
    as a result of anything other than an accident.” 
    Id. Nowhere in
    its opinion does the Pennsylvania Supreme
    Court specifically mention the trial court’s instruction to the jury
    regarding corpus delicti or counsel’s failure to object to it.
    Significantly, the Pennsylvania Supreme Court specifically
    found certain claims waived for failure to present them to the
    PCRA court – Jacobs’ challenge to the jury instructions on
    corpus delicti is not mentioned in the list of waived claims. 
    Id. at 550
    & n.9. In other words, although Jacobs presented his jury
    instruction challenge, the Pennsylvania Supreme Court neither
    addressed it nor found it waived. We can only conclude that the
    Pennsylvania Supreme Court overlooked this aspect of Jacobs’
    corpus delicti claim.
    We must also conclude that the Pennsylvania Supreme
    Court would not have deemed this claim waived – that court
    considered on the merits several other claims in precisely the
    same posture.16 Because no state court has issued a decision on
    16
    Alternatively, for reasons discussed infra in section III.D,
    Pennsylvania’s application of its waiver rule in capital cases on
    PCRA appeal is not an adequate state procedural rule for
    purposes of determining whether this claim is procedurally
    33
    Jacobs’ due process challenge to the jury instructions, the
    deferential standards of review of § 2254(d)(1) do not apply.
    See 
    Everett, 290 F.3d at 508
    . Rather, we review this claim de
    novo. See 
    Appel, 250 F.3d at 210
    . Even so, for the following
    reasons, the District Court correctly concluded that these claims
    do not warrant granting federal habeas relief.
    1.     Jury Instruction on Corpus Delicti
    Under Pennsylvania law, the jury cannot consider a
    defendant’s out-of-court admission unless the jury first finds
    that the Commonwealth established the corpus delicti beyond a
    reasonable doubt. See 
    Reyes, 681 A.2d at 728
    . The federal Due
    Process Clause in turn protects a criminal defendant against
    conviction except upon proof beyond a reasonable doubt of
    every fact necessary to constitute the crime with which he is
    charged. In re Winship, 
    397 U.S. 358
    , 364 (1970). The Due
    Process Clause also requires that the jury be instructed on the
    necessity of proof beyond a reasonable doubt. Cool v. United
    States, 
    409 U.S. 100
    , 104 (1972). On federal habeas review, the
    relevant question is “whether the ailing instruction by itself so
    infected the entire trial that the resulting conviction violated due
    process . . . , not merely whether the instruction is undesirable,
    erroneous, or even universally condemned.” Martin v. Warden,
    Huntingdon State Correctional Inst., 
    653 F.2d 799
    , 809 (3d Cir.
    1981) (alteration in original) (quoting Henderson v. Kibbe, 
    431 U.S. 145
    , 154 (1977) and Cupp v. Naughton, 
    414 U.S. 141
    , 146-
    47 (1973)). “‘[A] single instruction to the jury may not be
    barred under federal habeas law.
    34
    judged in artificial isolation but must be viewed in the context
    of the overall charge.’” 
    Martin, 653 F.2d at 809-10
    (quoting
    
    Cupp, 414 U.S. at 146-47
    ).
    Here, Jacobs contends that the trial court violated his
    right to federal due process by failing to instruct the jury that it
    must find the corpus delicti beyond a reasonable doubt before
    considering his out-of-court confessions, as required by state
    law. A review of the instruction as it pertains specifically to
    Jacobs’ confessions reflects that the charge was not perfect. The
    trial court spent four transcript pages of the 44-page charge
    discussing “special rules” that apply when considering a
    defendant’s confession:
    In this case, the Commonwealth is presenting the
    testimony of the Defendant’s mother in the belief that it
    is a confession, an admission, by him that he committed
    these crimes, and there are special rules that apply to
    confessions.
    The Commonwealth has introduced evidence of a
    statement which it claims was made by the Defendant.
    Before you consider the statement as evidence against the
    Defendant you must find, first, that a crime in fact was
    committed; second, that the Defendant in fact made the
    statement; and third, that the statement was voluntary.
    Otherwise, you must disregard the statement.
    35
    Each juror should ultimately decide these questions for
    himself and thereby individually accept or reject the
    Defendant’s statement as evidence. You must not allow
    the fact that I admitted the statement into evidence to
    influence you in any way during your deliberations. . . .
    Now to get back to confessions. There does not appear
    to be a great deal of dispute that a crime was in fact
    committed, at least in regard to the death of Tammy
    Mock. Now that doesn’t – my saying that doesn’t make
    it a fact. Nothing is a fact in the case until you as jurors
    determine it to be a fact, but in the arguments of counsel,
    that was what I understood defense counsel to indicate.
    That’s the only reason I’m saying that. But that’s
    something for you to determine when you get out to the
    jury room. . . .
    So it appeared to the Court that the specific issue that you
    would have to focus on in this particular area is that the
    Defendant in fact made the statement. And in that
    regard, what you want to focus on in particular is was
    [sic] his actual words as he spoke them repeated to you.
    In other words, did he say that exact thing? And, of
    course, there’s been some varied testimony in regard to
    that. You’ve heard the statement from the witness on the
    stand, the mother. You’ve heard statements that she
    made on earlier occasions and her reasons as to why
    there is a distinction between the two, and you’ve also
    heard the Defendant say what his version of his statement
    or conversation was to his mother.
    36
    So you’re going to have to work out if it’s been proven
    to you beyond a reasonable doubt what his exact words
    were, and if you’re satisfied as to what the exact words
    were, then you may consider that along with finding that
    a crime has been committed and that the statement was
    voluntary.
    (Trial Tr., Vol. V, 9/18/92 at 786:20-789:20).
    Jacobs argues that the trial court’s charge is
    constitutionally infirm because it omitted any reference to the
    Commonwealth’s burden of proving the corpus delicti beyond
    a reasonable doubt, failed to distinguish between the deaths of
    Tammy and Holly, and “all but directed a verdict on the corpus
    delicti issue.” (Appellant’s Opening Br. at 40-41). While
    Jacobs’ criticisms of this portion of the charge are not entirely
    unfounded, it is apparent that he has neglected to examine the
    charge as a whole – rather, he has isolated the portion of the
    charge as it relates specifically to confessions and essentially
    excluded consideration of the remaining forty pages of the
    charge.
    In the charge, the trial judge referred numerous times to
    the Commonwealth’s burden to prove each and every element
    of the crime beyond a reasonable doubt. Never did the trial
    court suggest any other burden of proof or that Jacobs bore any
    burden whatsoever. Based on the charge as a whole, we find it
    extremely unlikely that the jury perceived that the
    Commonwealth’s burden was ever less than beyond a
    reasonable doubt. Additionally, the trial judge specifically
    instructed the jury that the murder of Tammy and the murder of
    37
    Holly required individual findings:
    And as always, there’s [sic] going to be two separate
    findings, first that Tammy Mock is dead and second that
    Holly Jacobs is dead, and I won’t repeat that each time.
    Please assume that applies to everything I’m going to
    say. You’ll have two separate findings for each one.
    (Id. at 804:7-804:12).
    To the extent that Jacobs argues that the trial court “all
    but directed a verdict,” this contention also lacks support based
    on an examination of the charge as a whole. In its general
    instructions, the trial court charged the jury:
    Now, how do you make that decision? Well, in effect
    you, collectively, are the judge of the facts. In effect,
    there’s [sic] two judges in the case. I’m the judge for the
    law and you must follow the law as I am now going to
    give it to you, but you are the judges of the facts and it’s
    totally up to you to determine exactly what happened and
    what’s been proved by the Commonwealth and whether
    it meets their burden and the verdict that flows from that
    after you apply the law to the facts as you find them.
    (Id. at 779:11-779:21).
    Moreover, the trial court specifically reminded the jury
    of its duty to determine the facts regarding Jacobs’ confession:
    “Each juror should ultimately decide these questions for himself
    and thereby individually accept or reject the Defendant’s
    38
    statement as evidence. You must not allow the fact that I
    admitted the statement into evidence to influence you in any way
    during deliberations.” (Id. at 787:9-787:14). The judge further
    noted that there did “not appear to be a great deal of dispute that
    a crime was in fact committed, at least in regard to the death of
    Tammy Mock . . . [but] my saying that doesn’t make it a fact.
    Nothing is a fact in the case until you as jurors determine it to be
    a fact.” (Id. at 788:7-788:12) (emphasis added). Contrary to
    Jacobs’ assertions, the trial court did distinguish the death of
    Tammy from that of Holly, and did not express an opinion
    whether a crime had been committed as to Holly.
    Notwithstanding the adequacy of the instructions as a
    whole, Jacobs relies on Commonwealth v. Ahlborn, 
    657 A.2d 518
    (Pa. Super. Ct. 1995), for the proposition that Pennsylvania
    law requires the trial court to specifically charge the jury to find
    the corpus delicti beyond a reasonable doubt. In Ahlborn, the
    trial court charged the jury that prior to considering the
    confession, it must find that a crime had, in fact, occurred. 
    Id. at 521-22.
    According to the Superior Court, such an instruction
    failed to convey the reasonable doubt standard and essentially
    diluted the Commonwealth’s burden of proof. 
    Id. at 522.
    According to Jacobs, the trial court’s failure to instruct the jury
    in compliance with Ahlborn violated his federal right to due
    process.
    Ahlborn supports the conclusion that the trial court must,
    as a matter of state law, specifically charge the jury to find the
    corpus delicti beyond a reasonable doubt, even if the trial court
    has correctly instructed the jury as to the Commonwealth’s
    overall burden. Nothing in Ahlborn suggests, however, that the
    39
    trial court’s instruction violated the federal Due Process Clause.
    Ahlborn examines only a single paragraph in the instruction
    regarding the defendant’s confession without considering the
    overall instructions. 
    Id. at 520-22.
    Such an analysis does not
    comport with the well-established principle of federal law that
    a single instruction must be viewed in light of the overall
    charge. See 
    Cupp, 414 U.S. at 146-47
    . Therefore, Ahlborn
    does not and should not govern whether the trial court’s corpus
    delicti instruction violated Jacobs’ constitutional right to due
    process.17 The District Court properly rejected this claim on the
    merits.
    2.      Ineffective Assistance of Counsel for
    Failure to Object to Jury Instructions
    Jacobs’ related claim is that trial counsel rendered
    ineffective assistance by failing to object specifically to the
    corpus delicti instruction. To the extent that this claim is based
    on counsel’s failure to object as a matter of federal law, this
    claim is without merit. For the reasons set forth previously,
    Jacobs cannot show a reasonable probability that the outcome of
    the proceeding would have been different if counsel had
    17
    We note also that Ahlborn was a direct appeal of a criminal
    conviction. The burden of demonstrating that an erroneous
    instruction was so prejudicial as to support a federal collateral
    attack on a state court judgment is greater than that required to
    establish error on direct appeal. See 
    Martin, 653 F.2d at 809
    .
    40
    objected based on the federal Due Process Clause.
    Whether counsel rendered ineffective assistance by
    failing to object to the corpus delicti charge under state law is a
    separate question. As described previously, Ahlborn suggests
    that the trial court must specifically charge that the
    Commonwealth must prove the corpus delicti beyond a
    reasonable doubt before the jury can consider an out-of-court
    admission. Significantly, the corpus delicti instruction at issue
    in Ahlborn is similar to the one given at Jacobs’ trial; the trial
    court in each case instructed the jury that it had to find “that a
    crime in fact” was committed. Ahlborn holds that such an
    instruction essentially dilutes the Commonwealth’s burden of
    proof.
    We cannot end our inquiry here, however, because both
    the Pennsylvania Supreme Court and the District Court ruled
    that the Commonwealth was not required to prove the corpus
    delicti of Holly’s murder under the closely related exception to
    the corpus delicti rule. As the Pennsylvania Supreme Court has
    explained:
    This exception comes into play where an accused is
    charged with more than one crime, and the accused
    makes a statement related to all the crimes charged, but
    the prosecution is only able to establish the corpus delicti
    of one of the crimes charged. Under those circumstances
    where the relationship between the crimes is sufficiently
    close so that the introduction of the statement will not
    violate the purpose underlying the corpus delicti rule, the
    statement of the accused will be admissible as to all the
    41
    crimes charged.
    Commonwealth v. Bardo, 
    709 A.2d 871
    , 874 (Pa. 1998).
    We agree that the closely related exception applies here.
    There is no question that the Commonwealth established the
    corpus delicti of Tammy Mock’s murder. Jacobs himself
    testified in court that he killed Tammy Mock when he lost
    control upon discovering that she had drowned Holly. The
    police found the bodies of both Tammy and Holly in the bathtub
    several days later. Because the closely related exception applies,
    the trial court was not required to instruct the jury that it must
    find the corpus delicti of Holly’s murder beyond a reasonable
    doubt. See 
    id. Jacobs counters
    that the closely related exception applies
    only to the admissibility tier of the corpus delicti rule.
    (Appellant’s Opening Br. at 44 n.24). According to Jacobs, the
    Pennsylvania Supreme Court has never applied the closely
    related exception to the second tier of the rule. (Id.). This is
    incorrect. In Bardo, for example, the Pennsylvania Supreme
    Court expressly considered whether “the trial court erred in its
    instruction to the jury on the corpus delicti 
    rule.” 709 A.2d at 875
    . The Pennsylvania Supreme Court relied squarely on the
    closely related exception to conclude that the claim was
    “meritless.” 
    Id. It follows
    that Jacobs’ claim of ineffective assistance
    based on counsel’s failure to raise a state law objection to the
    corpus delicti instruction must fail. If counsel had raised such
    an objection, there is no reasonable likelihood that the outcome
    42
    of the proceedings would have been any different. Likewise, if
    appellate counsel had raised this argument on direct appeal, it is
    unlikely that the Pennsylvania Supreme Court would have
    vacated Jacobs’ conviction for Holly’s murder.
    3.      Sufficiency of Evidence of Corpus
    Delicti
    Jacobs’ final claim based on the corpus delicti rule is that
    the evidence of Holly’s murder (apart from his out-of-court
    admission) is insufficient to support a finding beyond a
    reasonable doubt that the baby was killed by unlawful means.
    Jacobs asserts that Holly died from drowning under
    circumstances equally consistent with an accident as with a
    crime. (Appellant’s Opening Br. at 48). From this, Jacobs
    concludes that the Commonwealth failed to prove beyond a
    reasonable doubt that a crime had been committed.
    The short answer to this argument is that the
    Commonwealth was not required to prove the corpus delicti of
    Holly’s murder because the closely related exception applies.
    Even if it did not apply, this argument lacks merit. The
    circumstances of Holly’s death are not equally consistent with
    an accident as with a crime. Indeed, Jacobs testified that
    Tammy killed Holly to get back at him, and that he killed
    Tammy when he lost control at finding his baby dead. No
    persuasive evidence was presented at trial to establish that
    43
    Holly’s death was anything but a homicide.18
    For these reasons, we agree with the District Court that
    Jacobs’ claims based on the corpus delicti rule do not warrant
    federal habeas relief.
    C.    Ineffective Assistance of Counsel for Failing to
    Investigate and Present Evidence of Delois
    Jacobs’ Alcoholism
    At a preliminary hearing, Delois Jacobs testified that her
    son had admitted to her in telephone conversations that he killed
    both Tammy and Holly. At trial, however, Delois testified that
    she had been going through some problems and was very upset
    when Jacobs called her, and that she could not remember
    whether he admitted killing Holly. (Trial Tr., Vol. III, 9/16/92
    at 543:20-545:3, 549:2-551:12). Jacobs now claims that trial
    counsel rendered ineffective assistance by failing to investigate
    and present evidence that Delois had a long history of
    alcoholism and may have been intoxicated when Jacobs made
    out-of-court admissions to her.19
    The Pennsylvania Supreme Court rejected this claim on
    the merits because: (1) there was no evidence that Delois was
    18
    Common sense suggests that an infant of Holly’s age did
    not climb into the bathtub on her own and drown accidentally.
    19
    Jacobs exhausted this claim by presenting it in his PCRA
    petition and on PCRA appeal.
    44
    intoxicated at the time Jacobs confessed to her; and (2) trial
    counsel testified at the PCRA hearing that he did not want to
    undermine the credibility of Delois’ trial testimony by cross-
    examining her regarding her alcoholism. Jacobs 
    II, 727 A.2d at 549
    . According to the Pennsylvania Supreme Court, counsel
    had a reasonable basis for proceeding as he did and thus was not
    ineffective. 
    Id. The District
    Court likewise rejected this claim
    on the merits after concluding that counsel’s actions constituted
    sound trial strategy. Jacobs 
    III, 129 F. Supp. 2d at 414
    .
    We agree that this claim lacks merit. Jacobs’ assertion is,
    at best, that his mother may have been under the influence of
    alcohol at the time he confessed to her. We find no evidence
    establishing that Delois was intoxicated or that intoxication
    caused her to misrepresent the content of her conversations with
    Jacobs. Counsel testified at the PCRA hearing that he had
    spoken to Delois a couple of times before trial, and that she had
    never mentioned the possibility of intoxication. (PCRA Hearing
    Tr. 5/29/97 at 39:21-39:25). At the PCRA hearing, Delois
    testified that she did not remember whether she had been
    drinking alcohol the day Jacobs confessed to her. (PCRA
    Hearing Tr. 6/13/97 at 16:14-16:24). In other words, Jacobs has
    little factual support for his assertion of ineffective assistance in
    this regard.
    Additionally, Jacobs has failed to address how he was
    prejudiced by counsel’s failure to discover Delois’ alcoholism
    and potential intoxication. He does not explain how he can
    demonstrate a reasonable probability that he would have been
    acquitted of murdering Holly if counsel had attacked Delois’
    credibility. Delois’ testimony at trial plainly favored Jacobs – if
    45
    counsel had attacked Delois’ credibility with evidence of
    alcoholism, the jury could well have discounted her entire
    testimony, including that portion of her testimony which was
    favorable to Jacobs.
    In short, Jacobs has fallen short of demonstrating that he
    is entitled to federal habeas relief as to this claim. The District
    Court properly rejected this claim on the merits.
    D.     Ineffective Assistance of Counsel for Failing to
    Request Voir Dire Concerning Racial Bias
    Jacobs is African-American; Tammy Mock was white.
    Each member of the venire panel was white. During voir dire,
    trial counsel did not question any prospective juror concerning
    racial bias. Jacobs claims that trial counsel rendered ineffective
    assistance during voir dire for failing to inquire about racial
    bias, especially where a young African-American man was on
    trial for murdering his white girlfriend.
    The District Court declined to consider this claim.
    According to the District Court, this claim challenged counsel’s
    representation at the penalty phase, not at the guilt phase. The
    District Court believed that it need not address the merits of this
    issue because the death sentence had been vacated on other
    grounds. Jacobs 
    III, 129 F. Supp. 2d at 409-10
    .
    After reviewing Jacobs’ habeas petition and his reply
    memorandum in support filed in the District Court, we disagree
    46
    that this claim challenges only counsel’s representation at the
    penalty phase. This claim challenges counsel’s failure “to
    inquire concerning racial bias among the members of the jury,
    where the entire venire was white and the case involved the
    murder of a white female teenager and child by her African-
    American boyfriend.” (Pet. at 26). In his reply memorandum,
    Jacobs alleges that “counsel ineffectively failed to inquire
    concerning racial bias among members of the jury.” (Reply
    Mem. at 47). The discussion of this claim is included within the
    discussion of several other of counsel’s alleged errors regarding
    voir dire. (Id. at 46-58). Jacobs concludes this discussion in the
    following manner:
    Counsel’s numerous failures to protect Mr. Jacobs’ right
    to be tried by an impartial jury that would decide his guilt
    or innocence and sentence based on the law and the facts
    rather than preconceived bias, prejudice, or statements
    made about the case outside the court created an
    “unacceptable risk of . . . prejudice infecting the capital
    sentencing proceeding,” Turner v. 
    Murray, 476 U.S. at 37
    , in violation of Petitioner’s Sixth, Eighth and
    Fourteenth Amendment rights.
    (
    Id. at 5
    8). To conclude that this claim challenges the death
    sentence, but not the underlying convictions, is unduly
    restrictive.
    We consider next whether this claim is exhausted and
    thus subject to federal habeas review. According to the
    Commonwealth, this claim is procedurally barred because the
    Pennsylvania Supreme Court found it waived for failure to
    47
    present it to the PCRA court. (Appellees’ Br. at 36-37). The
    Commonwealth is correct that the Pennsylvania Supreme Court
    refused to consider this claim on the merits after finding it
    waived for failure to present it to the PCRA court. Jacobs 
    II, 727 A.2d at 548
    n.5.
    The fact that the Pennsylvania Supreme Court refused to
    consider this claim for procedural reasons does not necessarily
    render the issue procedurally barred on federal habeas review.
    A federal “habeas court ‘will not review a question of federal
    law decided by a state court if the decision of [the state] court
    rests on a state law ground that is independent of the federal
    question and adequate to support the judgment.’” Szuchon v.
    Lehman, 
    273 F.3d 299
    , 325 (3d Cir. 2001) (quoting Coleman v.
    Thompson, 
    501 U.S. 722
    , 729 (1991)). We have previously
    explained that a rule is adequate 20 only under the following
    conditions: “(1) the state procedural rule speaks in unmistakable
    terms; (2) all state appellate courts refused to review the
    petitioner’s claims on the merits; and (3) the state courts’ refusal
    in this instance is consistent with other decisions.” Doctor v.
    Walters, 
    96 F.3d 675
    , 683-84 (3d Cir.1996). In other words, a
    procedural rule is adequate only if it is “firmly established,
    readily ascertainable, and regularly followed at the time of the
    purported default.” 
    Szuchon, 273 F.3d at 327
    .
    Generally, Pennsylvania’s PCRA requires a petitioner to
    20
    There is no question that the Pennsylvania Supreme Court’s
    application of its waiver rule is independent from any federal
    question presented.
    48
    prove that his allegation of error has not been w aived. 42 Pa.
    Cons. Stat. Ann. § 9543(a)(3). An issue is deemed waived if the
    petitioner could have raised it but failed to do so before trial, at
    trial, during unitary review, on appeal or in a prior state
    postconviction proceeding. 
    Id. § 9544(b).
    Currently, the
    Pennsylvania Supreme Court enforces the waiver rule in capital
    cases on PCRA appeal, and generally deems an issue waived
    where the petitioner failed to present it to the PCRA court. See
    Commonwealth v. Albrecht, 
    720 A.2d 693
    , 700 (Pa. 1998).
    Prior to Albrecht, however, the Pennsylvania Supreme
    Court applied the relaxed waiver doctrine in capital cases on
    PCRA appeal. 
    Id. Under the
    relaxed waiver doctrine, the
    Pennsylvania Supreme Court declined to apply ordinary waiver
    principles in capital cases in an effort to prevent the court “from
    being instrumental in an unconstitutional execution.” 
    Id. On November
    23, 1998, the Pennsylvania Supreme Court in
    Albrecht expressly abandoned the relaxed waiver doctrine in
    capital cases on PCRA appeal. 
    Id. The relevant
    question, then,
    is whether Pennsylvania’s strict enforcement of the waiver rule
    in capital cases on PCRA appeal was “firmly established, readily
    ascertainable, and regularly followed at the time of the
    purported default.” 
    Szuchon, 273 F.3d at 327
    .
    According to the Pennsylvania Supreme Court, Jacobs
    waived his claim challenging counsel’s failure to request voir
    dire regarding racial prejudice when he failed to present it to the
    PCRA court. See Jacobs 
    II, 727 A.2d at 548
    n.5. Jacobs
    initiated PCRA proceedings by filing a pro se petition on
    January 13, 1997, which appointed counsel supplemented on
    May 23, 1997. The PCRA court denied many of Jacobs’ claims
    49
    in an oral decision rendered May 29, 1997. The PCRA court
    then denied all relief in a second oral decision on June 13, 1997.
    The Pennsylvania Supreme Court did not firmly establish its
    strict enforcement of the waiver rule in such cases until
    November 23, 1998, when it decided Albrecht, more than a year
    after Jacobs’ PCRA petition was denied. It follows that the
    Pennsylvania Supreme Court’s strict enforcement of its waiver
    rule in capital cases on PCRA appeal is not adequate to support
    the judgment for the purpose of finding a procedural default
    under federal habeas law. See 
    Szuchon, 273 F.3d at 327
    .
    Accordingly, we are free to examine the merits of Jacobs’
    claim.21
    “[A] capital defendant accused of an interracial crime is
    entitled to have prospective jurors informed of the race of the
    victim and questioned on the issue of racial bias.” Turner v.
    Murray, 
    476 U.S. 28
    , 36-37 (1991). The defendant must
    specifically request such an inquiry. 
    Id. at 37.
    “[T]he trial judge
    retains discretion as to the form and number of questions on”
    racial prejudice. 
    Id. Here, the
    potential jurors were never
    questioned concerning racial bias because trial counsel did not
    request it. The specific issue, then, is whether counsel rendered
    ineffective assistance by failing to request such voir dire.
    Under Strickland, a federal habeas court “must indulge
    a strong presumption that counsel’s conduct falls within the
    wide range of reasonable professional assistance.” Strickland,
    21
    Because no state court has rendered a decision on the merits
    of this claim, we review it de novo. See 
    Everett, 290 F.3d at 508
    .
    
    50 466 U.S. at 689
    . The defendant bears the burden of overcoming
    the presumption that “the challenged action might be considered
    sound trial strategy.” 
    Id. (internal quotation
    omitted). “When
    counsel focuses on some issues [and excludes] others, there is
    a strong presumption that he did so for tactical reasons rather
    than through sheer neglect.” Yarborough v. Gentry, 
    540 U.S. 1
    ,
    8 (2003). This presumption “has particular force where a
    petitioner bases his ineffective-assistance claim solely on the
    trial record, creating a situation in which a court may have no
    way of knowing whether a seemingly unusual or misguided
    action by counsel had a sound strategic motive.” 
    Id. at 5
    (internal quotation marks and citation omitted).
    Here, if Jacobs’ counsel had requested voir dire
    respecting racial prejudice, the trial court would have been
    constitutionally bound to grant his request. See 
    Turner, 476 U.S. at 36-37
    . Our review of the entire voir dire confirms that
    counsel did not ask any questions of any potential jurors
    regarding racial prejudice. Certainly nothing in the record
    suggests that Tammy Mock’s killing was racially motivated.
    Counsel reasonably could have believed that probing the jurors’
    potential racial prejudices might unduly emphasize the racial
    differences, somehow inject racial issues into a trial where none
    existed, or taint the jurors’ view of Jacobs and his attorney. In
    other words, counsel reasonably could have concluded that
    asking prospective jurors questions about racial prejudice would
    do more harm than good. Under these circumstances, and in the
    absence of any evidence to the contrary, we presume that
    counsel’s decision was sound trial strategy.
    Jacobs has failed to overcome this strong presumption.
    51
    He notes “continuing racial tensions in York” since the 2001
    indictment of a former mayor for his alleged participation in the
    slaying of an African-American woman in 1969. (Appellant’s
    Opening Br. at 63 n.37). He does not describe the racial climate
    in York at the time of his trial in 1992, nor does he explain how
    the racial tensions in 2001 could have impacted his trial.
    Jacobs also asserts that his trial was racially sensitive
    because it involved an interracial sexual relationship between an
    African-American man and his white girlfriend. He suggests
    that counsel always has a duty to inquire into possible racial bias
    in a racially sensitive case. (Appellant’s Opening Br. at 64, 66).
    Whether Jacobs properly characterizes his trial as racially
    sensitive is subject to debate.22 Even if his trial were racially
    sensitive, Jacobs cites no federal authority for the proposition
    that the Constitution requires defense counsel to inquire into
    possible racial bias in each racially sensitive case.23 Moreover,
    22
    To the extent that Jacobs relies on Reynolds v.
    Commonwealth, 
    367 S.E.2d 176
    (Va. Ct. App. 1988), for the
    proposition that his case was racially sensitive, we are not
    persuaded. Reynolds’ case was “replete with racial epithets”
    and “racially inflammatory evidence.” 
    Id. at 182.
    Our scrutiny
    of the record here reveals no such evidence.
    23
    Jacobs cites Butler v. State, No. C.C.A. 1163, 
    1988 WL 63526
    (Tenn. Crim. App. June 23, 1988), holding that counsel
    was ineffective for failing to request voir dire regarding racial
    prejudice. We find nothing in Butler suggesting that the
    Constitution requires counsel to inquire about racial prejudice in
    52
    we decline to adopt a rule which would require counsel to
    inquire as to racial prejudice, even where he reasonably deemed
    such questioning a poor strategic choice.
    For these reasons, we conclude that Jacobs has failed to
    demonstrate that trial counsel performed deficiently by failing
    to inquire into possible racial bias on voir dire. Accordingly, his
    claim of ineffective assistance in this regard fails.
    IV.    CONCLUSION
    For the foregoing reasons, we will reverse the District
    Court’s order denying habeas corpus relief on Jacobs’ claim of
    ineffective assistance of counsel during the guilt phase by
    failing to investigate, discover, and present evidence to support
    a diminished capacity defense to the murder of Tammy Mock.
    We will remand this matter to the District Court with
    instructions to enter an order granting the writ of habeas corpus
    conditioned on the Commonwealth’s grant of a new trial, within
    a reasonable time, on the charge of murdering Tammy Mock.
    We will affirm the District Court’s denial of habeas corpus relief
    on each of Jacobs’ remaining claims.
    each racially sensitive case, however. We note also that the
    Tennessee Supreme Court reversed the court of appeals’
    unpublished decision. See Butler v. State, 
    789 S.W.2d 898
    (Tenn. 1990).

    SCIRICA, Chief Judge, concurring in part and dissenting in
    part.
    I concur with much of the Court’s opinion, but I
    respectfully dissent as to Part III.A. In my view, the
    Pennsylvania Supreme Court’s analysis does not constitute an
    unreasonable application of clearly established federal law that
    warrants vacating Jacobs’ conviction and granting him a new
    trial.
    Jacobs claims his trial counsel was constitutionally
    ineffective for failing to adequately investigate and present
    evidence supporting a diminished capacity defense. More
    specifically, he argues that the affidavits of Drs. Kessel and
    Fleming– each of whom performed psychiatric examinations of
    Jacobs for his state collateral appeal– establish that his trial
    counsel’s efforts to obtain expert testimony were so deficient
    and prejudicial as to rise to the level of constitutional
    ineffectiveness.
    The District Court found trial counsel not ineffective on
    the guilt phase.24 Because I believe the District Court properly
    applied the standards of the Antiterrorism and Effective Death
    24
    Because the District Court dismissed this claim based solely
    on a review of the state court records– without conducting its
    own evidentiary hearing– our review is plenary. Marshall v.
    Hendricks, 
    307 F.3d 36
    , 50 (3d Cir. 2002) (citing Duncan v.
    Morton, 
    256 F.3d 189
    , 196 (3d Cir. 2001)).
    54
    Penalty Act of 1996 (“AEDPA”), 25 I would affirm.
    I. Discussion
    As the Court notes, the relevant inquiry here is whether
    the Pennsylvania Supreme Court’s decision involved an
    “unreasonable application” of clearly established federal law.26
    25
    The Pennsylvania Supreme Court addressed this claim on
    the merits on PCRA appeal. See Commonwealth v. Jacobs, 
    727 A.2d 545
    , 548-49 (Pa. 1999). Thus, we apply the standards set
    forth in the Antiterrorism and Effective Death Penalty Act of
    1996 (“AEDPA”), P.L. 104-132, 110 Stat. 1214., 28 U.S.C. §
    2254(d); see also Appel v. Horn, 
    250 F.3d 203
    , 210 (3d Cir.
    2001) (deferential standards provided by the AEDPA apply only
    to those claims adjudicated on the merits in state court
    proceedings). Under the AEDPA, a petitioner is entitled to
    habeas relief only where the state court proceedings “resulted in
    a decision that was contrary to, or involved an unreasonable
    application of, clearly established Federal law,” or “resulted in
    a decision that was based on an unreasonable determination of
    the facts in light of the evidence presented in the State court
    proceeding.” 28 U.S.C. § 2254(d)(1).
    26
    The applicable federal law in this instance is the well-
    settled two-prong test established by the Supreme Court in
    Strickland v. Washington, 
    466 U.S. 668
    (1984). Under
    Strickland, in order to merit habeas relief based on a claim of
    ineffective assistance of counsel petitioner must demonstrate
    that: (1) his attorney’s performance was deficient, and (2) he
    was prejudiced by this deficiency. 
    Strickland, 466 U.S. at 687
    .
    55
    A state court decision involves an “unreasonable application of
    federal law” under 28 U.S.C. § 2254(d)(1) where it “correctly
    identifies the governing legal rule but applies it unreasonably to
    the facts of a particular prisoner’s case.” Williams v. Taylor,
    To demonstrate deficiency, petitioner must establish that
    counsel’s performance “fell below an objective standard of
    reasonableness.” 
    Id. at 688.
    To overcome the presumption that
    counsel was effective, petitioner bears the burden of establishing
    that counsel’s performance was unreasonable under “prevailing
    professional norms.” 
    Id. at 688.
    “In evaluating counsel’s
    performance, we are ‘highly deferential’ and ‘indulge a strong
    presumption’ that, under the circumstances, counsel’s
    challenged actions ‘might be considered sound . . . strategy.’”
    Buehl v. Vaughn, 
    166 F.3d 163
    , 169 (3d Cir. 1999) (citing
    
    Strickland, 466 U.S. at 689
    ). To show prejudice, petitioner must
    demonstrate that “counsel’s errors were so serious as to deprive
    the defendant of a fair trial, a trial whose result is reliable.”
    
    Strickland, 466 U.S. at 687
    .
    Ultimately, the “benchmark for judging any claim of
    ineffectiveness must be whether counsel’s conduct so
    undermined the proper functioning of the adversarial process
    that the trial cannot be relied on as having produced a just
    result.” 
    Id. Put differently,
    “the issue is not what conduct is
    ‘prudent or appropriate, but only what is constitutionally
    compelled.’” Rompilla v. Horn, 
    355 F.3d 233
    , 246 (3d Cir.
    2004) (quoting Burger v. Kemp, 
    483 U.S. 776
    , 794 (1987)), cert.
    granted 
    125 S. Ct. 27
    (2004). Indeed, the Sixth Amendment
    does not require perfection; instead, it “simply . . . ensure[s] that
    criminal defendants receive a fair trial.” 
    Id. (quotations omitted).
    56
    
    529 U.S. 362
    , 407-08 (2000). For a federal court to find a state
    court’s application of law unreasonable, “the state court’s
    decision must have been more than incorrect or erroneous.”
    Wiggins v. Smith, 
    539 U.S. 510
    , 520 (2003) (citing Lockyer v.
    Andrade, 
    538 U.S. 63
    , 75 (2003)). Rather, “[t]he state court’s
    application must have been ‘objectively unreasonable.’” 
    Id. at 5
    21 (citing 
    Williams, 529 U.S. at 409
    ). As the Supreme Court
    has stressed, “an unreasonable application is different from an
    incorrect one.” Bell v. Cone, 
    535 U.S. 685
    , 694 (2002).
    The Pennsylvania Supreme Court evaluated petitioner’s
    claim as follows:
    Next, Appellant maintains that trial
    counsel was ineffective in failing to adequately
    investigate and present evidence supporting a
    diminished capacity defense. The PCRA court
    rejected this assertion as the record clearly
    revealed that trial counsel pursued such a defense
    on behalf of Appellant.
    Specifically, trial counsel testified at the
    PCRA hearing regarding his efforts in this regard.
    He stated that initially when he suggested to
    Appellant that a psychiatric evaluation should be
    conducted, Appellant rejected the idea claiming
    his sanity. Trial counsel stated that he was able to
    convince Appellant to submit to a psychiatric
    evaluation and that he arranged for such
    evaluation to be performed. Following this
    examination, trial counsel was contacted by the
    examining psychiatrist and told that, in his
    opinion, Appellant was sane and knew what he
    57
    was doing at the time of the alleged crimes.
    Counsel, therefore, told the psychiatrist not to
    issue a report and he was not called to testify at
    trial.
    Nevertheless, consistent with Appellant’s
    trial testimony, trial counsel pursued a diminished
    capacity defense in regards to the killing of
    Tammy Mock. Appellant testified at trial that he
    was not responsible for Holly Jacobs’ death. He
    stated that when he handed Holly Jacobs to
    Tammy Mock, who was in the bathtub, Mock
    drowned Holly. Appellant testified that after this
    incident occurred, he ‘lost it’ and killed Tammy
    Mock. Given this admission, trial counsel argued
    that Appellant was incapable of forming a
    specific intent to kill given his mental state at the
    time of the killing.
    Based on the results of the psychiatric
    evaluation, and given Appellant’s trial testimony,
    it is clear that trial counsel did investigate and
    pursue a diminished capacity defense on behalf of
    Appellant to the best of his ability. Accordingly,
    as trial counsel had a reasonable basis for
    proceeding as he did, he cannot be deemed
    ineffective.
    Commonwealth v. 
    Jacobs, 727 A.2d at 548-49
    .
    Like the District Court, I believe this analysis does not
    constitute an unreasonable application of federal law. In my
    view, the Court has undertaken de novo review, conducting its
    own independent application of Strickland rather than focusing
    58
    its review on an analysis of whether the state court’s application
    of that test was reasonable under controlling and clearly
    established law. A habeas petitioner, however, “must do more
    than show that he would have satisfied Strickland’s test if his
    claim were being analyzed in the first instance, because under §
    2254(d)(1), it is not enough to convince a federal habeas court
    that, in its independent judgment, the state-court decision
    applied Strickland incorrectly.” 
    Bell, 535 U.S. at 698-99
    (citing
    
    Williams, 529 U.S. at 411
    ).
    The Pennsylvania Supreme Court’s conclusion that trial
    counsel did not render ineffective assistance was a reasonable
    application of Strickland. Testimony at the PCRA hearing
    established that trial counsel ordered a psychiatric evaluation for
    Jacobs. Despite Jacobs’ initial reluctance, trial counsel arranged
    an examination with Dr. Robert Davis, who examined petitioner
    “to determine if he had a major mental illness or other
    impairment that would render him incompetent to stand trial or
    that would negate or reduce his criminal responsibility.” Dr.
    Davis was aware, specifically, of counsel’s intent to present a
    diminished capacity defense, and he was provided with the
    police report detailing the allegations underlying the offense.
    Dr. Davis found no evidence of mental illness and orally
    informed trial counsel that, in his opinion, Jacobs suffered no
    psychiatric illness, knew what he was doing at the time of the
    alleged murders and was sane.
    Relying on Dr. Davis’ opinion, trial counsel did not
    request a written report. As intended, counsel presented a
    59
    diminished capacity defense at trial. 27 Highlighting Jacobs’
    testimony that he “lost it” and killed Tammy Mock because she
    had drowned his daughter Holly Jacobs, trial counsel argued to
    the jury that Jacobs’ mental state rendered him incapable of
    forming a specific intent to kill at the time of Mock’s death.
    This record supports the state court’s conclusion.
    Accordingly, I would find that the Pennsylvania Supreme Court
    applied Strickland reasonably in concluding that trial counsel’s
    investigation and presentation of a diminished capacity defense
    did not constitute ineffective assistance of counsel.
    The Court places great weight on the Pennsylvania
    Supreme Court’s apparent disregard of trial counsel’s failure to
    provide Dr. Davis with several “highly relevant facts” and other
    information “necessary . . . to conduct a proper evaluation.”
    This appears to include trial counsel’s failure to provide Dr.
    Davis with additional background information and his failure to
    ask petitioner’s mother, during her interview, about her son’s
    mental health background.
    Strickland requires a reviewing court to consider the
    totality of the circumstances, but I believe the state court’s
    analysis did just that. Significantly, Dr. Davis did not state that
    he was incapable of forming a conclusion on the information
    available to him and the results he obtained through the
    psychiatric examination. As the District Court noted, the record
    27
    It bears noting that a diminished capacity defense under
    Pennsylvania law is “extremely limited” in scope.
    Commonwealth v. Cuevas, 
    832 A.2d 388
    , 393 (Pa. 2003).
    60
    revealed no request by Dr. Davis for background information
    beyond that provided by counsel. Nor was there any reason that,
    after receiving the doctor’s opinion, counsel would have been on
    notice to track down medical records or to pursue other inquiries
    that might possibly relate to Jacobs’ mental health.
    The right to counsel “does not require that a criminal
    defense attorney leave no stone unturned and no witness
    unpursued.” Berryman v. Morton, 
    100 F.3d 1089
    , 1101 (3d Cir.
    1996). With the benefit of hindsight, petitioner now argues that
    trial counsel might have been able to present psychiatric
    testimony at trial suggesting Jacobs suffered from mild mental
    retardation, organic brain damage, or cognitive impairments.
    The test for ineffectiveness, however, “is not whether counsel
    could have done more; perfection is not required. Nor is the test
    whether the best criminal defense attorneys might have done
    more. Instead the test is . . . whether what counsel did was
    within the wide range of reasonable professional assistance.”
    
    Rompilla, 355 F.3d at 246
    (citations omitted).
    Like the PCRA Court, the Pennsylvania Supreme Court,
    and the District Court, I believe trial counsel’s decisions to
    arrange a pyschiatric examination, rely on the professional
    opinion of Dr. Davis, and present a diminished capacity defense
    supported by Jacobs’ testimony, are not constitutionally
    defective. Furthermore, I believe the Pennsylvania Supreme
    Court reasonably applied Strickland in reaching this conclusion.
    For these reasons, I would affirm the District Court’s denial of
    petitioner’s ineffective assistance claim regarding trial counsel’s
    failure to investigate and present a diminished capacity defense
    61
    at the guilt phase.28
    28
    Until now, no court has addressed the prejudice prong of
    Strickland at the guilt phase. The doctors’ testimony by
    affidavit was only presented for the first time in Jacobs’ PCRA
    appeal before the Pennsylvania Supreme Court. Because the
    Pennsylvania Supreme Court found trial counsel’s performance
    constitutionally adequate at both the guilt and penalty phases, it
    did not consider the affidavits under either prejudice prong of
    Strickland. The District Court also found trial counsel not
    ineffective on the guilt phase, and thus did not address
    Strickland’s prejudice prong on the first degree murder verdict.
    The affidavits of Drs. Kessel and Fleming, therefore– the
    evidence upon which this Court relies in concluding there exists
    a reasonable probability that the jury, had it heard testimony
    from these two doctors, would have found Jacobs guilty of third
    degree murder rather than first degree murder– have never been
    factually contested in any court. In my view, vacating the
    conviction is inappropriate where the issue of prejudice has
    never been engaged on the verdict of first degree murder. At
    most, then, this case should be remanded to the District Court to
    consider prejudice at the guilt phase of the trial.
    62
