    OPINION
    _________________
    RONALD LEE GILMAN, Circuit Judge. Brett X. Hartman was convicted in an Ohio state
    court of aggravated murder and was sentenced to death. After exhausting his state-court remedies,
    he filed a petition for habeas corpus in federal district court. The district court denied his petition,
    but issued a certificate of appealability (COA) regarding one of Hartman’s claims. This court added
    three more claims to the COA. For the reasons set forth below, we AFFIRM the judgment of the
    district court.

    Nos. 04-4138/4185/4243                     Hartman v. Bagley                                     Page 2
    I. BACKGROUND
    A.     Factual background
    In Hartman’s direct appeal from his conviction, the Ohio Supreme Court set forth the
    following summary of the relevant facts:
    Defendant met Winda Snipes at a bar in Akron, Ohio, sometime during 1997.
    Subsequently, they engaged in sexual intercourse on several occasions. During the
    late afternoon of September 9, 1997, defendant went to Snipes’s apartment and
    brutally murdered her by tying her to the bed, stabbing her one hundred thirty-eight
    times, slitting her throat, and cutting off her hands.
    Defendant was convicted of aggravated murder, kidnapping, and tampering with
    evidence, and sentenced to death. In order to establish defendant’s guilt, the state
    introduced statements defendant had made to the police and to a fellow inmate in jail,
    and the testimony of a co-worker that defendant mentioned cutting off a victim’s
    hands as a way to eliminate evidence in the O.J. Simpson case. The state also
    introduced as evidence defendant's bloody tee-shirt and Snipes’s watch recovered
    from defendant's apartment, and forensic testimony linking defendant to the murder.
    State’s case
    Around 2:20 a.m. on September 9, 1997, defendant met Snipes at the Bucket Shop,
    an Akron bar. Defendant kissed Snipes on the cheek and they talked. Thereafter,
    defendant and Snipes left the bar and they went to her apartment across the street.
    Around 3:00 a.m., David Morris, an acquaintance of defendant and Snipes, left the
    Inn Between, another Akron bar. While walking past Snipes’s apartment on his way
    home, Morris observed Snipes and defendant through the upstairs window of her
    apartment. Morris testified that Snipes was yelling at defendant about touching stuff
    that was not his. Defendant closed the window blinds and “obviously she wasn’t
    very happy about it” because she “scolded” him and reopened the blinds.
    That afternoon, at around 4:30 p.m., Snipes was observed crossing a street in a
    nearby business district. She was never seen alive again.
    Defendant had the day off from work on September 9. According to Richard
    Russell, a bartender at the Inn Between, defendant entered the bar at around 8:00
    p.m. and appeared nervous and hyper, and talked excessively. Thereafter, defendant
    was in and out of the bar five to six times between 9:00 and 10:30 p.m.
    Defendant first contacted the police on September 9 with a series of anonymous 911
    calls, which he later admitted to. His first 911 call at 9:59 p.m. reported the location
    of a mutilated body. The police officers dispatched to Snipes’s address entered
    Snipes’s apartment building and checked around, but left after finding nothing
    unusual. Meanwhile, defendant viewed the police unit’s arrival and departure while
    hiding behind a tree across the street. Defendant then made another 911 call telling
    the police to return to the apartment building and provided further instructions on the
    body’s location.
    Akron police officers responding to this call entered Snipes’s unlocked apartment
    and found her naked, mutilated body lying on the bedroom floor. Snipes’s leg was
    draped across the bed, a pair of pantyhose tied her ankle to the bed leg, and a white
    Nos. 04-4138/4185/4243                    Hartman v. Bagley                                   Page 3
    plastic chair was on top of her body. Snipes’s hands were cut off and have never
    been found.
    Around 10:45 p.m., defendant was at the Inn Between with Morris, while police units
    were across the street investigating Snipes’s murder. Morris, having learned that
    Snipes had been murdered, suggested to defendant that he should talk to the police,
    since Morris had observed defendant at Snipes’s apartment the previous evening.
    Shortly before midnight, defendant approached Detective Gregory Harrison while
    he was at a mobile crime lab parked outside Snipes’s apartment. Defendant walked
    up to Harrison and said, “I hear it’s pretty bad in there,” and asked if Harrison had
    “ever seen anything so gruesome.” Later that evening, defendant approached
    Harrison a second time and spontaneously mentioned that Snipes was a whore, “that
    she slept around a lot,” and that “he had slept with her * * * and he had even slept
    with her the night before at 3:00.” In their final contact at around 3:00 a.m.,
    defendant was “kind of mumbling to himself” and Harrison heard defendant say that
    “she was a whore, she was a big whore, she got what she deserved.”
    Between 11:30 p.m. and 12:15 a.m., defendant also approached Akron Police Lt.
    John A. Lawson near the murder scene and, “rather abruptly said, ‘You’re going to
    find my semen in her and my prints over there.’” When Lawson asked why,
    defendant said he “had been with her earlier that morning, the morning of the 9th,”
    and that he had had sex with her.
    At 12:15 a.m. on September 10, defendant spoke to Detective Joseph Urbank in front
    of the apartment building. Defendant began their conversation by announcing that
    “he had sex with the victim the night before.” Moreover, defendant said he did not
    know her name but “only knew her as psycho bitch and that everybody knew that if
    you got drunk and were horny you went to go see her, you went to go see psycho
    bitch.”
    Defendant also told Urbank that he went to Snipes’s apartment at 2:30 a.m. on
    September 9, and “she started dancing a little bit.” He “lifted her onto the bed,
    undressed her,” and “they started having vaginal intercourse.” Defendant said that
    he was disappointed because Snipes refused to have anal intercourse, and he left her
    apartment around 3:30 a.m. However, defendant claimed that he did not know
    anything about the murder until the bartender at the Inn Between told him about it
    on the evening of September 9.
    Around 6:00 a.m. on September 10, police took defendant to the Akron police
    station, where he was interviewed by Lawson and Urbank. During his interview,
    defendant denied making the 911 calls, and denied hiding behind a tree across from
    Snipes’s apartment. Then, defendant changed a part of his story and admitted hiding
    behind a tree near the murder scene.
    Following the September 10 police interview, the police searched defendant’s
    apartment with his consent. The police seized defendant’s bloody tee-shirt from
    underneath the headboard of his bed, a pair of his jeans, and his boots. Police found
    a knife on his dresser and Snipes’s wristwatch on defendant’s bed stand.
    Police took defendant to the police station after the search of his apartment. While
    awaiting transfer to the Summit County Jail, defendant approached Detective John
    R. Gilbride and blurted out, “I was the one that called the police” and “I’m the one
    that found the body.”
    Nos. 04-4138/4185/4243                     Hartman v. Bagley                                    Page 4
    Defendant told Gilbride he had been sexually involved with Snipes since February
    1997, and had sexual intercourse with Snipes during the early morning hours of
    September 9. Defendant stated that “after having sex the psycho bitch threw him out
    of the apartment stating that her boyfriend was coming over.” He left around 3:30
    a.m. and returned to his own apartment.
    According to Gilbride, defendant said that he slept until 6:00 p.m. on September 9,
    and then took the bus to the Inn Between bar around 7:30 p.m. Gilbride testified that
    while going into the Inn Between bar, defendant noticed a light on in Snipes’s
    apartment and decided to visit her. According to Gilbride, defendant gained entry
    to the apartment through an unlocked door and claimed that he found her dead body
    in her bedroom. Defendant said that he unsuccessfully tried to pick her body off the
    floor, noticed that her hands had been cut off, and “freaked out.” Thinking “I’m
    going to get busted for this,” defendant washed her blood off his hands and clothes,
    tried wiping down everything he touched, removed evidence linking him to her
    apartment, and went home.
    Snipes was stabbed one hundred thirty-eight times. Bruising on her ankles indicated
    that she was alive when she was tied to the bed. Additionally, sperm was found in
    her vagina and anus. The medical examiner concluded that Snipes had died from
    strangulation and a slit throat either in the late afternoon or early evening of
    September 9.
    Police found defendant’s bloody fingerprint on the leg of the white chair draped over
    Snipes’s body, and police found another of defendant’s fingerprints on Snipes’s
    bedspread. An expert witness testified that the long linear blood patterns found on
    defendant’s tee-shirt and Snipes’s bedspread were applied by a long-bladed knife.
    Further, the blood patterns found on defendant’s tee-shirt were applied while the
    tee-shirt was lying flat, and not while defendant was wearing it.
    At trial, the prosecution introduced a set of defendant’s knives, including a meat
    cleaver, a knife, and a knife sharpener that defendant kept at the Quaker Square
    Hilton, where he worked as a chef.
    Christopher Hoffman, a Hilton co-worker, testified that he talked to defendant in
    August 1997 about the O.J. Simpson trial. According to Hoffman, defendant said
    that Simpson could have disposed of evidence against him by cutting off the victim’s
    hands and eliminating “fibers and hair and skin that might be found on the
    fingernails.”
    Bryan Tyson, a fellow inmate at the Summit County Jail, testified that during a
    jailhouse conversation, defendant admitted that he had killed Snipes. According to
    Tyson, defendant said that “he pushed himself on her, something in his mind
    snapped, she was hitting him, he lost his temper, did things he regretted, killed her.”
    Then, defendant said that he had “tried to make it look like a burglary,” admitted
    cutting off Snipes’s hands, and mentioned a hacksaw, and jokingly said “‘Don’t
    leave home without it,’ like the credit card commercial.”
    Defense case
    Jessica O’Neill, an acquaintance of defendant, talked on the phone with defendant
    on September 9. Phone records showed that O’Neill called defendant’s apartment
    and spoke with him at 3:12 p.m. and 4:50 p.m. She also claimed that she talked with
    defendant on the phone around 6:30 or 7:00 p.m.
    Nos. 04-4138/4185/4243                     Hartman v. Bagley                                    Page 5
    The defense also introduced evidence suggesting an alternative suspect, Jeff Nichols.
    Nichols lived across the hallway from Snipes’s apartment until he moved out of his
    apartment around September 1, 1997. Nichols worked as a handyman for the
    apartment building and had access to the landlord’s keys to other apartments.
    In January 1997, Jeffrey Barnes, a friend of Snipes, was visiting Snipes’s apartment
    when Nichols came to her door. According to Barnes, Nichols “got up right to her
    door and then he said, ‘Slit the bitch’s throat, cut her up,’ and called her a slut and
    all other kind of vulgar names.” Barnes reported this incident to the police upon
    hearing about Snipes’s murder.
    On an evening prior to September 1, 1997, Linda Zarski, a neighbor in Snipes’s
    apartment building, heard Snipes pounding on Nichols’s door and screaming that she
    wanted her shirt.
    On another occasion prior to the murder, Linda Kinebrew, a neighbor living at the
    apartment, “heard [Nichols] arguing, telling [Snipes] to let him in and she wouldn’t.”
    Carol Parcell, defendant’s mother, provided an alibi. Defendant lived at his mother’s
    apartment, and Parcell claimed that when she came home on September 9 at 6:15
    p.m., her son was sleeping in his bedroom. According to Parcell, defendant woke up
    at 7:00 p.m., got ready, left the apartment at 7:30 p.m., and returned to the apartment
    around 8:15 p.m.
    Defendant testified on his own behalf. He admitted having sex with Snipes several
    times over the past year and during the early morning hours of September 9 when he
    was at Snipes’s apartment. After having sex, defendant returned to his apartment at
    about 3:30 a.m., slept until 6:15 p.m., left his apartment at 7:35 p.m., and returned
    to the Inn Between bar.
    Before reaching the Inn Between, defendant noticed that Snipes’s bathroom light was
    on at her apartment, and he decided to visit her to see if he could “get laid.”
    Defendant entered Snipes’s apartment through an unlocked door and found her
    mutilated body in the bedroom. Defendant tried to “get her up and put her on the bed
    * * * to see if there was anything else I could help with.”
    Defendant “freaked out” after noticing Snipes had no hands and realized he “could
    get in a lot of trouble” if he was placed at the scene. Thus, he washed her blood off
    his hands, wiped down the cupboards, chair handles, and anything else he might have
    touched, gathered whatever items he could find that belonged to him, and left
    Snipes’s apartment. Defendant “ran home” and threw the items taken from Snipes’s
    apartment into a nearby dumpster. Upon arriving home, defendant changed his shoes
    and hid the bloody tee-shirt so that his mother would not find it.
    Thereafter, defendant hurried back to the Inn Between bar and started drinking.
    When he was “semi-intoxicated,” defendant made the anonymous 911 calls reporting
    the location of Snipes’s body, admitted standing behind a tree watching the police
    arrive at Snipes’s apartment, and later approached the police to report that he had
    been at the apartment the previous evening.
    Defendant introduced photographs taken of his naked body following his arrest to
    show the absence of bruises and injuries. Defendant explained that a cut on his
    elbow had occurred at work while he was moving crates.
    Nos. 04-4138/4185/4243                       Hartman v. Bagley                                Page 6
    Defendant acknowledged talking with Chris Hoffman about the O.J. Simpson case
    but did not recall discussing anything about cutting off a victim’s hands.
    Defendant knew Tyson as a fellow inmate but denied making any jailhouse
    admissions that he murdered Snipes.
    Trial result
    The grand jury indicted defendant on two counts of aggravated murder, including
    one count of murder with prior calculation and design and one count of felony
    murder. A capital specification relating to murder during a kidnapping was included
    in the felony murder count. He was also charged with kidnapping and tampering with
    evidence.
    The jury found defendant guilty of all offenses and recommended death for Snipes’s
    murder. The trial court sentenced defendant to ten years for kidnapping, five years
    for tampering with evidence, and death for the aggravated murder of Snipes.
    State v. Hartman, 
    754 N.E.2d 1150
    , 1158-61 (Ohio 2001). The Ohio Supreme Court affirmed
    Hartman’s conviction and death sentence. 
    Id. at 1183.
    B.     Subsequent case history
    After the Ohio Supreme Court decided Hartman’s direct appeal, he initiated state
    postconviction proceedings by setting forth 11 grounds for relief. The state trial court, however,
    denied his petition as to all of them. Hartman filed an appeal from the denial of his postconviction
    petition, but he missed the filing deadline. To excuse this procedural default, Hartman asserted that
    he did not receive timely notification that his postconviction petition had been denied, and that he
    filed his appeal diligently after receiving belated notification. Finding this excuse to be without
    merit, the Ohio Court of Appeals sua sponte dismissed Hartman’s appeal as untimely. The Ohio
    Supreme Court then declined jurisdiction to hear his postconviction petition. It also denied
    Hartman’s subsequent motion to reopen that was based, among other reasons, on the claim that his
    counsel had been constitutionally ineffective during the penalty phase of his trial.
    After exhausting his state postconviction remedies, Hartman initiated federal habeas corpus
    proceedings pursuant to 28 U.S.C. § 2254 in January of 2003, again asserting 11 grounds for relief.
    He also argued that DNA testing was necessary because none had been performed during the course
    of his trial. Although he admitted having vaginal intercourse with Snipes on the morning of the
    murder, he denied having anal intercourse with her. He therefore asserted that DNA testing on the
    semen samples taken from the two cavities would exculpate him. The district court granted funds
    for the DNA testing. Unfortunately for Hartman, the tests ultimately showed that both samples
    matched his DNA.
    In August of 2004, the district court denied Hartman’s § 2254 petition in its entirety, but
    granted a certificate of appealability (COA) on the issue of whether sufficient evidence supported
    Hartman’s kidnapping capital specification and separate kidnapping conviction. Hartman v. Bagley,
    
    333 F. Supp. 2d 632
    (N.D. Ohio 2004). This court expanded Hartman’s COA by adding the issues
    of whether Hartman’s counsel provided ineffective assistance at the mitigation phase, whether the
    trial judge gave improper “acquittal-first” jury instructions, and whether certain of the prosecutor’s
    statements made during the penalty phase amounted to prosecutorial misconduct. We now address
    each of these four issues.
    Nos. 04-4138/4185/4243                        Hartman v. Bagley                                    Page 7
    II. ANALYSIS
    A.      Standard of review and legal framework
    “In a habeas corpus appeal, we review a district court’s legal conclusions de novo, but will
    not set aside its factual findings unless they are clearly erroneous.” Dyer v. Bowlen, 
    465 F.3d 280
    ,
    283-84 (6th Cir. 2006). The standard for reviewing for state-court determinations, by contrast, is
    governed by the Antiterrorism and Effective Death Penalty Act (AEDPA), codified at 28 U.S.C.
    § 2254(d). Under the AEDPA standard, a federal court
    may not grant a writ of habeas to a petitioner in state custody with respect to any
    claim adjudicated on the merits in state court unless (1) the state court’s decision was
    contrary to, or involved an unreasonable application of, clearly established Federal
    law, as determined by the Supreme Court . . . or (2) the state court’s decision was
    based on an unreasonable determination of the facts in light of the evidence
    presented in the State court proceedings.
    Benge v. Johnson, 
    474 F.3d 236
    , 241 (6th Cir. 2007) (quotation marks omitted).
    A state-court decision is considered “contrary to . . . clearly established federal law” if it is
    “diametrically different, opposite in character or nature, or mutually opposed.” Williams v. Taylor,
    
    529 U.S. 362
    , 405 (2000) (quotation marks omitted). Alternatively, to be deemed an “unreasonable
    application of . . . clearly established Federal law,” a state-court decision on the merits must be
    “objectively unreasonable,” not simply erroneous or incorrect. 
    Id. at 409-11.
    Findings of fact made
    by the state court are presumed to be correct unless rebutted by “clear and convincing evidence.”
    
    Benge, 474 F.3d at 241
    .
    The AEDPA standard of review, however, applies only to “any claim that was adjudicated
    on the merits in State court proceedings.” Danner v. Motley, 
    448 F.3d 372
    , 376 (6th Cir. 2006).
    Consequently, where a state court has not previously ruled on the merits of a claim, we apply the
    de novo standard of review. 
    Id. B. Ineffective
    assistance of counsel during the penalty phase
    The first COA issue is whether Hartman’s defense counsel rendered ineffective assistance
    during the penalty phase of the trial. Hartman’s claim encompasses his counsel’s alleged failure to
    either fully investigate or adequately present mitigating evidence. This claim was not fully
    adjudicated on the merits in the Ohio courts, so we must also examine whether it has been
    procedurally defaulted.
    1.      Ohio court rulings
    Hartman did not present his ineffective-assistance claim on direct appeal. He fully presented
    the claim to the state trial court, however, during his postconviction proceedings. The trial court
    determined that res judicata barred the claim because Hartman had failed to raise it on direct appeal
    and “there was no proffer of evidence outside the record.” To the contrary, our review of the record
    indicates that Hartman’s claim of ineffective assistance of counsel was based primarily on a forensic
    psychology report that was, in fact, outside the record. As explained above, however, Hartman
    failed to timely appeal the state trial court’s ruling. The Ohio Court of Appeals therefore sua sponte
    dismissed his appeal.
    Hartman also raised a portion of his ineffective-assistance-of-counsel claim in his motion
    to reopen his direct appeal. In that motion, Hartman asserted that he had received ineffective
    assistance based on his counsel’s allegedly inadequate presentation of mitigation evidence as well
    Nos. 04-4138/4185/4243                       Hartman v. Bagley                                  Page 8
    as several other grounds not relevant to the present appeal. As to his mitigation-evidence claim,
    however, Hartman’s motion asserted ineffectiveness only in relation to his counsel’s alleged failure
    to adequately present evidence of his alcoholism. The Ohio Supreme Court entered a summary
    order denying Hartman’s motion to reopen without explanation.
    2.      District court’s ruling
    In analyzing Hartman’s federal habeas petition, the district court concluded that, based on
    the state-court procedural history set forth above, Hartman had procedurally defaulted all portions
    of his present claim not relating to his alleged alcoholism. 
    Hartman 333 F. Supp. 2d at 671-72
    .
    Reviewing only that portion of Hartman’s claim, the district court determined that Hartman’s
    counsel was not ineffective. 
    Id. at 674.
    The district court did not address, however, the effect of
    Hartman’s efforts to raise the entirety of his claim in his state postconviction proceedings, including
    the Ohio trial court’s determination that the claim was barred by res judicata and the Ohio Court of
    Appeals’s sua sponte dismissal of his postconviction appeal.
    3.      Our review
    This court applies a four-part test to determine whether a claim has been procedurally
    defaulted:
    (1) the court must determine that there is a state procedural rule with which the
    petitioner failed to comply; (2) the court must determine whether the state courts
    actually enforced the state procedural sanction; (3) the state procedural rule must
    have been an adequate and independent state procedural ground upon which the state
    could rely to foreclose review of a federal constitutional claim; and (4) if the court
    has determined that a state procedural rule was not complied with and that the rule
    was an adequate and independent state ground, then the petitioner must demonstrate
    that there was cause for his failure to follow the rule and that actual prejudice
    resulted from the alleged constitutional error.
    Monzo v. Edwards, 
    281 F.3d 568
    , 576 (6th Cir. 2002). Reviewing Hartman’s postconviction
    petition, the state trial court expressly relied on res judicata to determine that Hartman’s claim was
    barred. “In Ohio, res judicata has long been held to bar consideration of constitutional claims in
    post-conviction proceedings brought under Ohio Rev. Code Ann. section 2953.21 when those claims
    have already been or could have been fully litigated either before judgment or on direct appeal from
    that judgment.” 
    Id. (citing State
    v. Perry, 
    226 N.E.2d 104
    , 105-06 (Ohio 1967)). A claim that relies
    on evidence outside the record, however, may be raised for the first time in postconviction
    proceedings if it could not have been brought on direct appeal based on the original record. State
    v. Gibson, 
    430 N.E.2d 954
    , 957 (Ohio Ct. App. 1980) (citing Ohio Rev. Code Ann. § 2953.21).
    In the present case, a review of the record reveals that Hartman’s ineffective-assistance claim
    is based primarily on evidence outside the record. He particularly relies on a forensic psychologist’s
    report that identified specific mitigating considerations, but which was not introduced at trial. This
    court has held that Ohio’s application of its res judicata rule generally constitutes an independent
    and adequate state ground that forecloses federal habeas review. See, e.g., 
    Monzo, 281 F.3d at 577
    .
    Nonetheless, this court has previously decided to review claims after determining that the “state
    court’s reliance upon its own rule of procedural default [was] misplaced” because the claims were
    in fact based primarily on credible evidence outside the record and could not have been raised on
    direct appeal. White v. Mitchell, 
    431 F.3d 517
    , 527 (6th Cir. 2005) (quotation marks omitted); see
    also Hill v. Mitchell, 
    400 F.3d 308
    , 314 (6th Cir. 2005) (finding that the petitioner’s ineffective-
    assistance claim was not barred under Ohio’s default rule). Here, we similarly conclude that
    Hartman’s postconviction ineffective-assistance claim is not procedurally barred. The
    Nos. 04-4138/4185/4243                        Hartman v. Bagley                                   Page 9
    psychologist’s report upon which Hartman principally relies was not part of the original trial record
    and the claim could not otherwise have been properly litigated on direct appeal.
    Hartman faces a second barrier to our review of his ineffective-assistance claim, however,
    because he failed to timely appeal the state trial court’s ruling that the majority of his claim was
    procedurally barred. He concedes that he filed his appeal over nine months after the judgment
    dismissing his petition was entered. Under Rule 4(A) of the Ohio Rules of Appellate Procedure,
    Hartman had 30 days from the date of entry to file a timely notice of appeal. Hartman does not
    contest that the Ohio Court of Appeals’s dismissal of his postconviction appeal pursuant Rule 4(A)
    would ordinarily represent an independent and adequate state ground foreclosing review of his
    federal constitutional claim. He argues, however, that he can demonstrate cause and prejudice
    sufficient to overcome the default. See 
    Monzo, 281 F.3d at 576
    .
    To establish cause, Hartman must present a substantial reason that is external to himself and
    cannot be fairly attributed to him. See Jamison v. Collins, 
    291 F.3d 380
    , 386 (6th Cir. 2002)
    (holding that the prosecution’s withholding of Brady evidence from the petitioner’s attorneys
    qualified as a “substantial reason for the default that is external to [the petitioner]”). Hartman asserts
    in this regard that neither he nor his attorney ever received formal notice of the state trial court’s
    order denying his petition. According to the docket, a copy of the order was sent only to Hartman,
    and not to his attorney. In support of his claimed nonreceipt, Hartman submitted an affidavit from
    a prison employee stating that no legal mail for Hartman was received during the relevant time
    period. The government raises no argument in response.
    Hartman has thus established cause to excuse the procedural default resulting from his failure
    to timely appeal the denial of his postconviction petition. We will defer analyzing the related issue
    of prejudice until our evaluation of the merits of his claim, which is to be reviewed de novo because
    of the absence of a prior state adjudication on this issue. See Joseph v. Coyle, 
    469 F.3d 441
    , 462-63
    (6th Cir. 2006) (concluding that a demonstration of prejudice under Strickland “likewise establishes
    prejudice for purposes of cause and prejudice” in the procedural-default context); 
    Danner, 448 F.3d at 376
    (applying the de novo standard of review to a claim not adjudicated on the merits by the state
    court).
    Hartman’s claim that he received ineffective assistance of counsel during the penalty phase
    of his trial centers on his counsel’s alleged failure to investigate and present mitigating evidence
    based on a report from forensic psychologist Dr. James Siddall. Hartman concedes that his counsel
    performed some investigation. Counsel interviewed several members of Hartman’s family,
    including his aunt, Arletta Hartman, and his half-sister, Rhea Wolpert; procured the services of Dr.
    Siddall; and arranged for Dr. Siddall to interview Hartman as well as his mother and aunt. In his
    final report, Dr. Siddall listed 10 mitigating factors that he had discovered in connection with
    Hartman’s case. These factors include Hartman’s family history of alcoholism, his unstable
    childhood involving frequent moves to different caretakers and new environments, his problems
    with hyperactivity, his instances of running away from home and living on the streets, his
    hospitalization for an alcohol overdose, his problems with drugs and alcohol throughout adolescence
    and early adulthood, and his recent purported stabilization shortly before the murder. The report
    also noted Hartman’s claims that his step-father had physically abused him and his step-mother had
    sexually abused him. Dr. Siddall added, however, that these abuse claims were not corroborated by
    his interviews with family members.
    In order to demonstrate ineffective assistance under Strickland, Hartman must show both that
    (1) his counsel’s performance was deficient, and (2) the deficient performance prejudiced him.
    Strickland v. Washington, 
    466 U.S. 668
    , 687 (1984). Hartman claims that his counsel’s performance
    was deficient because counsel did not enter Dr. Siddall’s report into evidence and failed to further
    investigate or adequately present evidence regarding the factors listed in the report. The Warden
    Nos. 04-4138/4185/4243                       Hartman v. Bagley                                 Page 10
    argues in response that Hartman’s counsel made a strategic decision not to present the report itself,
    but instead to call family witnesses to testify regarding the mitigating circumstances identified in
    the report. Furthermore, the Warden asserts that any deficiencies did not prejudice Hartman because
    the allegedly significant evidence cited in the report would simply have been cumulative to the
    testimony and argument already presented. See Broom v. Mitchell, 
    441 F.3d 392
    , 410 (6th Cir.
    2006) (“[T]he failure to present additional mitigating evidence that is merely cumulative of that
    already presented does not rise to the level of a constitutional violation.”)
    Outside of the jury’s presence, Hartman’s counsel explained to the court that “Dr. Siddall
    delineated, I think, ten separate mitigating factors and I think the family members will talk about
    virtually all of those in one way or another.” He then called Hartman’s half-sister and aunt to testify
    on Hartman’s behalf during the penalty phase, and both described many of the factors listed in Dr.
    Siddall’s report. They both testified about Hartman’s chaotic upbringing that involved his parents’
    divorce and his frequent moves to different caretakers, his hyperactivity, his severe problems with
    drugs and alcohol at a young age, his alcohol-overdose incident, the alcoholism in his family, and
    his running away from home and living on the streets. The penalty-phase opening statement and
    summation presented by Hartman’s counsel also emphasized these factors, as well as Hartman’s age
    and his lack of adult felony convictions.
    Nevertheless, the district court noted that counsel’s overall presentation of mitigating
    evidence was “not exemplary and in certain respects may have fallen short of the ABA’s standards,”
    particularly given that it “encompasses only 41 pages of transcript.” 
    Hartman, 333 F. Supp. 2d at 672
    . Hartman points out that the first mitigation witness, his half-sister Rhea Wolpert, had lived
    with Hartman only until he was 5 years old, and then not again until he turned 17. In the interim,
    she learned of events in his life primarily through their mother. The other defense witness,
    Hartman’s aunt Arletta Hartman, had taken care of Hartman for just three and one-half years during
    his adolescence. Moreover, Hartman argues that certain elements of Dr. Siddall’s report—such as
    the “alcohol and substance abuse, addiction, and mental health issues”—were not adequately
    presented through the witnesses’ testimony and required expert development. Neither witness was
    able to corroborate the abuse referenced in the report, and Wolpert specifically stated that Hartman’s
    step-father had not been abusive, but simply “strict.”
    On the other hand, Hartman cites no specific failures or overlooked evidence sufficient to
    prejudice him under Strickland. The family testimony described above addressed most if not all of
    the factors listed in Dr. Siddall’s report, albeit from a lay perspective. Furthermore, the decision not
    to introduce the report itself finds strategic justification. Although Dr. Siddall’s report identifies
    mitigating factors and contains some sympathetic commentary, other aspects of it paint a decidedly
    unsympathetic portrait.
    The report, for example, describes Hartman as an individual of “average intelligence,” with
    “no evidence of psychotic symptoms” and “intact” organic brain function. Despite the report’s
    description of Hartman’s troubled childhood, it states that he “seemed to be stabilizing” prior to the
    murder. Such findings run contrary to the unstable or impaired mental functioning that a defendant
    would typically attempt to demonstrate by way of mitigation. See, e.g., 
    Dickerson, 453 F.3d at 698
    -
    99 (holding that counsel’s failure to present mitigation evidence regarding the defendant’s
    borderline-retarded intelligence constituted prejudice).
    Hartman is diagnosed in the report with a mixed personality disorder typified by features of
    being “stubborn, self-centered, low in frustration tolerance, and often fail[ing] to conform to social
    norms with respect to lawful behaviors.” Dr. Siddall further explained in the report that Hartman
    “portray[s] himself in a manner which is exceptionally free of common shortcomings to which other
    individuals will admit.” Given that, prior to the murder, Hartman was generally able to conform his
    behavior to the law during his adult life in spite of this disorder, a jury might view the report’s
    Nos. 04-4138/4185/4243                       Hartman v. Bagley                               Page 11
    portrayal of Hartman’s personality deficits as simply off-putting rather than mitigating. Dr. Siddall
    himself in fact chose not to include Hartman’s personality disorder in his list of “factors [that] are
    relevant to mitigation.”
    In light of these arguably unhelpful elements that are mixed in with the mitigating elements
    of the report, counsel might quite reasonably have made a strategic decision to present the report’s
    mitigation findings through the more sympathetic lens of family members’ testimony. Hartman
    counters that his counsel should have employed an alternate strategy of calling Dr. Siddall to testify
    in order to soften the impact of the report’s “cold words.” This alternate strategy, however, would
    simply carry a different set of risks. Moreover, Hartman’s argument plainly invites us to second
    guess his counsel’s strategic decisionmaking. Counsel’s statements to the court that he had
    reviewed Dr. Siddall’s report and planned to present the factors outlined therein through the
    testimony of family members invoke the oft-repeated directive that “strategic choices made after
    thorough investigation of law and facts relevant to plausible options are virtually unchallengeable.”
    See 
    Strickland, 466 U.S. at 690
    .
    Ultimately, no evidence cited by Hartman, either from Dr. Siddall’s report or elsewhere,
    “differ[s] in a substantial way—in strength and subject matter—from the evidence actually presented
    at sentencing.” See 
    Hill, 400 F.3d at 319
    . Hartman’s habeas brief is instead replete with contentions
    that counsel failed to “expand on” or “corroborate[]” or “fully develop” the factors listed in Dr.
    Siddall’s report. For example, Hartman asserts that counsel’s mitigation investigation was
    inadequate because counsel “failed to obtain or present records from juvenile court or the juvenile
    detention facilities . . . [or from] child welfare agencies.” Although the ABA standards indeed
    recommend obtaining such government records, Hartman argues that, if presented to the jury, the
    records would have simply “corroborated and detailed” the testimony actually presented. See
    Dickerson v. Bagley, 
    453 F.3d 690
    , 694 (6th Cir. 2006) (discussing the ABA guidelines for
    mitigation investigations).
    These allegations typify Hartman’s ineffective-assistance claim and distinguish it from the
    cases in which habeas relief has been granted. See, e.g., Wiggins v. Smith, 
    539 U.S. 510
    , 515 (2003)
    (holding that ineffective assistance occurred where counsel introduced “no evidence of [the
    defendant’s] life history” despite existing evidence of brutal childhood abuse); Hamblin v. Mitchell,
    
    354 F.3d 482
    , 485, 490 (6th Cir. 2003) (holding that counsel’s assistance was ineffective because
    he “did nothing” in preparation and “did not present the jury with any mitigating evidence”);
    
    Dickerson, 453 F.3d at 698
    -99 (determining that prejudice arose from counsel’s failure to investigate
    evidence of the defendant’s borderline-retarded IQ and abusive childhood).
    Confronted with this difficulty in his argument, Hartman contends that cumulative evidence
    must nonetheless be taken into account in the reweighing process that requires us to determine if
    there is a reasonable probability that, but for counsel’s errors, “the result of the proceeding would
    have been different.” 
    Strickland, 466 U.S. at 694
    . The necessary reweighing of evidence, however,
    is not evaluated simply in terms of volume. As this court has previously stated, “[o]ur cases reject
    a requirement that any later-identified cumulative mitigating evidence must have been introduced
    in order for counsel to be effective.” Clark v. Mitchell, 
    425 F.3d 270
    , 286 (6th Cir. 2005).
    Hartman alternatively argues that he is entitled to a remand to the district court for an
    evidentiary hearing regarding whether his counsel’s allegedly ineffective assistance in the penalty
    phase of the trial prejudiced him. He requested an evidentiary hearing in his initial state-court
    postconviction petition and before the district court below, but both courts denied his request.
    Assuming that he avoids the 28 U.S.C. § 2254(e)(2) bar, we nonetheless conclude that Hartman has
    not alleged sufficient facts to warrant an evidentiary hearing on this issue. The Supreme Court
    recently explained that, “[i]n deciding whether to grant an evidentiary hearing, a federal court must
    consider whether such a hearing could enable an applicant to prove the petition’s factual allegations,
    Nos. 04-4138/4185/4243                       Hartman v. Bagley                                 Page 12
    which, if true, would entitle the applicant to federal habeas relief.” Schriro v. Landrigan, 
    127 S. Ct. 1933
    , 1940 (2007). Furthermore, “[b]ecause the deferential standards prescribed by § 2254 control
    whether to grant habeas relief, a federal court must take into account those standards in deciding
    whether an evidentiary hearing is appropriate.” 
    Id. In the
    present case, Hartman’s allegations focus exclusively on the mitigating factors
    addressed in Dr. Siddall’s report. As detailed above, his counsel’s mitigation presentation addressed
    these factors, even if not to the extent that Hartman desires in retrospect. We therefore conclude that
    Hartman is not entitled to relief on his claim of ineffective assistance of counsel during the penalty
    phase of the trial.
    C.      The “acquit first” jury instruction
    Hartman’s second COA issue is whether the trial court erroneously instructed the jury that
    they must first unanimously “acquit” Hartman of the death penalty before considering possible life
    sentences. Prior to the jury beginning its deliberation in the penalty phase, the trial judge instructed
    the jurors as follows:
    If all 12 members of the jury find by proof beyond a reasonable doubt that the
    aggravating circumstances . . . are sufficient to outweigh the mitigating factors, then
    you must return such finding to the court . . . .
    I instruct you, as a matter of law, that if you make such a finding, then you have no
    choice and must make a recommendation to the court that the sentence of death be
    imposed on the Defendant, Brett X. Hartman.
    ...
    On the other hand, if after considering all of the evidence raised at trial which is
    relevant to the issues before you, the testimony, other evidence, and the arguments
    of counsel, you cannot unanimously agree that the State of Ohio proved beyond a
    reasonable doubt that the aggravating circumstances, as I have defined them,
    outweigh the mitigating factors, then you’ll return your recommendation reflecting
    your decision.
    In this event, you will then proceed to determine which of the three possible life
    imprisonment sentences to impose.
    In addition, the judge informed the jury that “[w]hen all 12 of you, and I repeat, all 12 jurors agree
    upon a verdict, you will sign the verdict form in ink and advise the Court of this fact.” The verdict
    forms themselves are addressed in greater detail below.
    1.      Ohio Supreme Court’s ruling
    In evaluating this claim, the Ohio Supreme Court determined that, “[c]ontrary to the
    defendant’s contention, the trial court never instructed the jury that it had to unanimously reject the
    death penalty before it could consider a life sentence.” 
    Hartman, 754 N.E.2d at 1171
    . The Court
    further explained that “[t]he instructions explicitly advised the jurors that if they were unable to
    unanimously agree to recommend death, they shall consider life sentences,” and concluded that
    because “[t]he jury was . . . implicitly advised that a single juror could prevent the death penalty,”
    the instruction was proper. 
    Id. Nos. 04-4138/4185/4243
                          Hartman v. Bagley                                 Page 13
    2.      District court’s ruling
    The district court addressed this claim by comparing the state trial court’s jury instructions
    to those deemed constitutionally sound in Scott v. Mitchell, 
    209 F.3d 854
    (6th Cir. 2000).
    Characterizing the instructions in Scott as “virtually identical” to the instructions given here, the
    district court concluded that the instructions in question passed constitutional muster. 
    Hartman, 333 F. Supp. 2d at 671
    . Furthermore, the court cited Roe v. Baker, 
    316 F.3d 557
    , 563 (6th Cir. 2002),
    as another case where this court “found no constitutional violation when the sentencing court failed
    to instruct the jury that unanimity was not required before the jury could consider a life sentence.”
    
    Hartman, 333 F. Supp. 2d at 671
    . The district court noted, however, that this court’s opinion in
    Davis v. Mitchell, 
    318 F.3d 682
    (6th Cir. 2003), “gives support” to Hartman’s argument,
    characterizing the instructions held unconstitutional in that case also as “substantially identical” to
    the instructions given by the trial court here. Nevertheless, the district court concluded that it was
    bound by the prior precedent of Scott and Roe because “a panel cannot overrule another panel.”
    
    Hartman, 333 F. Supp. 2d at 671
    n.16.
    3.      Our review
    Hartman argues that the Ohio Supreme Court’s ruling on his claim does not warrant
    deference under AEDPA because the Court’s ruling was so cursory as to preclude review of whether
    it reasonably applied federal law. The Warden does not address this argument. Although Hartman
    is correct that the Ohio Supreme Court failed to cite any federal law in support of its determination,
    the Court nevertheless articulated the governing legal standard that it applied to evaluate the
    instructions in this case. Furthermore, the Court relied extensively on its own prior holding in State
    v. Brooks, 
    661 N.E.2d 1030
    (Ohio 1996), which did directly address the federal law cited by
    Hartman. But see 
    Danner, 448 F.3d at 376
    (“Any consideration of the [applicable federal law]
    contained within the state case law upon which the state courts relied is too attenuated to consider
    the [federal-law] claim to have been adjudicated on the merits”). Ultimately, we need not resolve
    this issue because, even reviewing Hartman’s claim de novo, we agree with the Ohio Supreme
    Court’s conclusion that the instructions were not improper.
    An acquittal-first jury instruction is “[a]ny instruction requiring that a jury must first
    unanimously reject the death penalty before it can consider a life sentence.” Davis v. Mitchell, 
    318 F.3d 682
    , 689 (6th Cir. 2003) (emphasis added). This court has held that such instructions are
    unconstitutional and provide grounds for habeas relief. 
    Id. Under Ohio
    law, however, the jury must
    unanimously agree on the final sentence imposed, whether it be death or a term of life imprisonment.
    See 
    id. Thus, even
    though the jury may not be required to unanimously “acquit” a defendant of
    death before considering life sentences, Ohio law requires that the jury be instructed that their
    ultimate sentencing decision must be unanimous.
    Hartman urges that the instructions given in this case, although not explicitly erroneous, were
    ambiguous and subject to an unconstitutional interpretation. The Supreme Court has held that, in
    evaluating such an argument, the appropriate inquiry centers on “whether there is a reasonable
    likelihood that the jury has applied the challenged instruction” in an unconstitutional manner. Boyde
    v. California, 
    494 U.S. 370
    , 380 (1990) (applying the “reasonable likelihood” examination to
    determine that an allegedly ambiguous jury instruction was not unconstitutional). Hartman urges
    that there is a reasonable likelihood that the jury misinterpreted the trial court’s instructions as
    requiring unanimity at every stage of deliberation, including the question of whether the mitigating
    factors outweighed the aggravating circumstances.
    We believe that the district court erred in determining that the instructions given in this case
    were substantially identical to those evaluated in Davis and Scott. (Roe did not specifically address
    instructions analogous to those at issue here.) The instructions in those cases and, more recently,
    Nos. 04-4138/4185/4243                        Hartman v. Bagley                                 Page 14
    in Spisak v. Mitchell, 
    465 F.3d 684
    (6th Cir. 2006), all began by explaining to the jury that “if all
    twelve members of the jury find . . . that the aggravating circumstances . . . outweighs [sic] the
    mitigating factors, . . . then you must recommend to the court that a sentence of death be imposed.”
    
    Id. at 709;
    see also 
    Davis, 318 F.3d at 684
    ; 
    Scott, 209 F.3d at 873
    . The trial court in the present
    case, to be sure, began with a similar instruction, informing the jury that their determination must
    be unanimous in order to recommend imposing the death penalty.
    Where the instructions given by the trial court materially differ from those evaluated in
    Davis, Scott, and Spisak, however, is in the crucial portion just following the above-quoted
    instruction. In the prior cases cited, the state trial court’s next instruction explained: “On the other
    hand, if after considering all of the relevant evidence . . . you find that the State failed to prove . .
    . that the aggravating circumstances . . . outweigh the mitigating factors, you will then proceed to
    determine which of [the] possible life imprisonment sentences to recommend.” 
    Spisak, 465 F.3d at 709-10
    (emphasis added); see also 
    Davis, 318 F.3d at 685
    ; 
    Scott, 209 F.3d at 873
    .
    The state trial court in Davis added: “[T]hat is, you must find that the State has failed to
    prove beyond a reasonable doubt that the aggravating circumstances which the defendant was found
    guilty of committing outweigh the mitigating 
    factors.” 318 F.3d at 685
    (emphasis omitted). In
    Mapes v. Coyle, 
    171 F.3d 408
    (6th Cir. 1999), the state trial court gave substantially identical
    instructions, but then went a step further by adding: “That is, you must unanimously find that the
    State has failed to prove beyond a reasonable doubt that the aggravating circumstances of which the
    defendant was found guilty of committing outweigh the mitigating factors.” 
    Id. at 416
    (emphasis
    added).
    This court in Davis held that the above-quoted language ambiguously instructed the jury
    what to do in the event that “you find” that the state failed to prove that the aggravating
    circumstances outweighed the mitigating factors because the instruction did not specify whether that
    “finding” needed to be unanimous. 
    Davis, 318 F.3d at 690
    . The courts in Davis and Spisak went
    on to examine the totality of the jury instructions given and concluded that there was a reasonable
    likelihood that the jury would have filled in this instructional void by drawing from other sources
    that required unanimity, such as the verdict forms or, as in Davis, the general instruction given in
    “close proximity” that “since this is a criminal case, the law requires that in order for you to reach
    a decision all 12 of you must be in agreement.” 
    Davis, 318 F.3d at 684
    .
    Here, the trial court’s instructions left no such void. After instructing the jurors as stated
    above regarding what to do in the event that all 12 agreed that the aggravating circumstances
    outweighed the mitigating factors, the court explained: “On the other hand, if after considering all
    of the evidence . . . you cannot unanimously agree that the State . . . proved beyond a reasonable
    doubt that the aggravating circumstances . . . outweigh the mitigating factors, then you’ll return your
    recommendation reflecting your decision. In this event, you will then proceed to determine which
    of the three possible life imprisonment sentences to impose.” (Emphasis added.)
    The above instructions correctly and explicitly state that anything short of unanimous
    agreement regarding whether the aggravating circumstances outweigh the mitigating factors required
    the jury to proceed to determine which possible life sentence to impose. Notably, the court did not
    employ the “if . . . you find” or “you must find” language used in cases like Davis and Spisak, but
    instead instructed the jurors, first, what to do if they did unanimously find that the aggravating
    circumstances outweighed the mitigating factors, and then, second, what to do if they could not
    unanimously so find. These instructions are therefore readily distinguishable from those held to be
    susceptible to an unconstitutional acquittal-first interpretation in Davis and Spisak.
    Relying on this court’s holding in Davis, Hartman further asserts that the jury verdict forms
    used by the Ohio trial court permitted an unconstitutional interpretation. He argues that the forms
    Nos. 04-4138/4185/4243                        Hartman v. Bagley                                  Page 15
    could be interpreted to erroneously indicate that a life verdict may be rendered only if the jury
    unanimously finds that the aggravating circumstances do not outweigh the mitigating factors. The
    death-sentence verdict form used in Hartman’s case was in fact similar to those used in prior cases.
    It provided, in pertinent part, that “[w]e the jury . . . do find . . . that the aggravating circumstances
    outweigh the mitigating factors . . . . We, the jury, recommend the sentence of death be imposed
    . . . .” (Emphasis added.) Compare 
    Spisak, 465 F.3d at 710
    ; 
    Scott, 209 F.3d at 873
    -74. All 12
    jurors were required to sign the form.
    The central point argued by Hartman, however, concerns the life-sentence verdict forms.
    In prior cases analyzed by this court, Ohio’s life-sentence verdict forms provided that “we the jury
    . . . do find that the aggravating circumstances . . . are not sufficient to outweigh the mitigating
    factors present,” and required the signatures of all 12 jurors. 
    Spisak, 465 F.3d at 710
    (emphasis
    added); 
    Davis, 318 F.3d at 690
    ; 
    Scott, 209 F.3d at 874
    . In both Davis and Spisak, the court
    concluded that this wording contributed to the potential misunderstanding that unanimity was
    required in order to consider life sentences.
    The verdict forms used in Hartman’s trial differed from those used in other recent death-
    penalty cases that this court has reviewed. Although the death-sentence verdict forms were the
    same, the life-sentence verdict forms provided that “we the jury . . . do not find, by proof beyond a
    reasonable doubt, that the aggravating circumstances outweigh the mitigating factors.” (Emphasis
    added.) Again, all 12 jurors were required to sign the form. The difference in the life-sentence
    verdict forms used in this case is significant. Whereas both the life-sentence and death-sentence
    verdict forms in prior cases expressed a finding and required the signature of all jurors, only in
    Hartman’s case did the life-sentence verdict forms profess a nonfinding regarding whether the
    aggravating circumstances outweighed the mitigating factors. This wording conforms to the trial
    court’s earlier proper instructions that, essentially, anything short of a unanimous agreement that the
    aggravating circumstances outweighed the mitigating factors necessitated a life sentence. In Goff
    v. Bagley, No. 1:02-cv-307, 
    2006 WL 3590369
    , at *10 (S.D. Ohio Dec. 1, 2006), the Southern
    District of Ohio recently reached a similar conclusion in analyzing a life-sentence verdict form
    substantially identical to the ones employed in Hartman’s case.
    This court in Williams v. Anderson, 
    460 F.3d 789
    , 811-13 (6th Cir. 2006), attempted to
    resolve in dicta what the district court in this case perceived to be the tension among this court’s
    holdings regarding acquittal-first jury instructions. We have no occasion to comment on that
    analysis here, however, because we conclude that the trial court’s instructions in this case differed
    materially from prior alleged “acquittal-first” instructions and did not create a reasonable likelihood
    that the jury applied them in an unconstitutional manner.
    D.      Prosecutorial misconduct
    Hartman’s third COA issue asserts that the prosecutor’s alleged implication during the
    penalty phase of the trial that the murder itself could be considered as an aggravating circumstance
    amounted to prosecutorial misconduct and violated Hartman’s constitutional rights. He specifically
    highlights four instances of alleged misconduct during the penalty phase in which the prosecutor
    stated:
    1.      The kidnapping is certainly the fact that Winda Snipes was restrained during
    the aggravated murder. She was tortured and the kidnapping encompasses
    torture, serious physical harm as well as the restraint. Okay?
    2.      And I submit to you you can consider the binding of her ankles to the bed,
    cord ligature around her neck, in excess of 130 stab wounds of [sic] cuts of
    different sorts to her body, some of which you learned from the Medical
    Nos. 04-4138/4185/4243                       Hartman v. Bagley                               Page 16
    examiner was [sic] before she was dead, terrorize, inflict serious physical
    harm. You can certainly consider those things.
    3.      I think you can certainly consider as part of the aggravating circumstance this
    Defendant’s actions after the murder, removing of evidence, trying to wipe
    down the scene, letting the mutilated body of Winda Snipes lay for several
    hours before –
    Mr. Whitney: Objection, objection.
    Court:          Overruled.
    Mr. Bandy: – the police are called, fleeing after the commission of a
    crime. Those kinds of actions can also be considered by you.
    4.      You think about the aggravating circumstance and I want you to think about
    it, take each one – everything that Attorney Bandy went over in regard to the
    kidnapping: Winda Snipes was restrained, she was terrorized, over 130 stab
    wounds, her throat was slit, her hands were removed, think about that
    aggravating circumstance.
    Hartman agues that the prosecutor’s references to facts pertaining to the murder itself were improper
    in the course of discussing the aggravating circumstances.
    1.      Ohio Supreme Court’s ruling
    The Ohio Supreme Court considered only the third statement of alleged prosecutorial
    misconduct that Hartman now highlights. 
    Hartman, 754 N.E.2d at 1173
    . In reference to that
    statement, the Court agreed that “it was wholly improper for the state to argue or suggest that the
    jury may consider the nature and circumstances of the offense as ‘part of the aggravating
    circumstances.’” 
    Id. Nevertheless, the
    Court concluded that the alleged misconduct did not
    prejudicially affect Hartman’s substantial rights for two reasons: (1) the statement “could not have
    made any difference in the outcome” in light of the jury’s finding of guilt regarding the aggravating
    circumstance of kidnapping and the “lack of compelling mitigating evidence,” and (2) the trial
    court’s clear and proper instruction to the jury that kidnapping was the only aggravating
    circumstance in the case. 
    Id. at 1173-74.
           2.      District court’s ruling
    In reviewing Hartman’s prosecutorial-misconduct claim, the district court specifically
    addressed only the fourth statement listed. The court agreed that the statement was improper, and
    added that it found “deeply troubling the prosecutor’s references to the gruesome nature of the crime
    and the post-mortem mutilation of the body.” 
    Hartman, 333 F. Supp. 2d at 664
    & n.13.
    Characterizing the statement as “a passing remark” and “limited in nature,” however, the court
    concluded that it did not render the penalty-phase proceeding “fundamentally unfair.” 
    Id. at 664.
    Moreover, the district court determined that the trial court properly instructed the jury as to the
    aggravating circumstance of kidnapping, and that Hartman had failed to overcome the presumption
    that the jury would follow the court’s instruction. 
    Id. 3. Our
    review
    The district court correctly noted that Hartman preserved his prosecutorial-misconduct claim
    for review by raising it before the Ohio Supreme Court. Of the four allegedly improper statements
    Hartman points to, we agree with the Ohio Supreme Court and the district court that the third and
    fourth statements were improper. As explained below with respect to Hartman’s fourth COA claim,
    however, his alleged restraint, “torture,” and “terroriz[ing]” of Snipes are central to establishing a
    necessary element of the kidnapping in this case: that Hartman’s restraint of Snipes led to a
    Nos. 04-4138/4185/4243                      Hartman v. Bagley                               Page 17
    substantial increase in the risk of physical harm to which she was exposed separate from that
    associated with her murder. The prosecutor’s first and second statements simply detail this serious
    harm separate from that associated with the murder to which Snipes was subjected by virtue of her
    restraint. Such “serious physical harm” is a statutory component of kidnapping, the sole aggravating
    circumstance charged against Hartman. See Ohio Rev. Code Ann. § 2905.01 (defining kidnapping
    as the asportation or restraint of another for the purpose of, among other things, “terroriz[ing], or
    . . . inflict[ing] serious physical harm on the victim”). For this reason, the prosecutor’s first and
    second statements were not misleading.
    By contrast, the third and fourth statements improperly encouraged the jury to take into
    account the means of killing—the slitting of Snipes’ throat—and the post-mortem mutilation of
    Snipes’s body as aggravating circumstances. But such isolated remarks generally do not rise to the
    level of a due process violation. In order to warrant habeas relief, Hartman must show that
    the statements of the prosecutor so infected the trial with unfairness as to make the
    resulting conviction a denial of due process. In order to deny due process, the
    misconduct must be so pronounced and persistent that it permeates the entire
    atmosphere of the trial or so gross as probably to prejudice the defendant.
    Simpson v. Jones, 
    238 F.3d 399
    , 409 (6th Cir. 2000) (citations and quotation marks omitted).
    The two statements in question do not fit this description. Moreover, as both the Ohio
    Supreme Court and the district court noted, the trial court properly instructed the jury to consider
    only the kidnapping as an aggravating circumstance of the murder. We presume that the jury
    followed these instructions “unless there is an ‘overwhelming probability’ that they were ignored.”
    See 
    Scott, 209 F.3d at 879
    (quoting Richardson v. Marsh, 
    481 U.S. 200
    , 208 (1987)).
    In the case before us, the jury convicted Hartman of the separate kidnapping offense, and the
    mitigation evidence was relatively weak. These factors substantially undermine Hartman’s attempt
    to rebut the presumption that the jury obeyed the court’s instruction to weigh only the kidnapping
    circumstance against the mitigating factors. The Ohio Supreme Court’s conclusion that the
    prosecutor’s closing argument did not violate Hartman’s rights, therefore, was not contrary to or an
    unreasonable application of clearly established federal law.
    E.     Sufficiency of the kidnapping evidence
    Hartman’s fourth and final COA issue asserts that insufficient evidence supported the jury’s
    conclusion that he was guilty of the kidnapping capital specification and the separate kidnapping
    charge. Specifically, he claims that the evidence was insufficient to establish either the standard
    elements of kidnapping or the additional element that the kidnapping was motivated by an animus
    separate from that which motivated the murder. This additional element was required in the present
    case both under Ohio law and under the Eighth Amendment principle that “an aggravating
    circumstance must genuinely narrow the class of persons eligible for the death penalty and must
    reasonably justify the imposition of a more severe sentence on the defendant compared to others
    found guilty of murder.” See Zant v. Stephens, 
    462 U.S. 862
    , 877 (1983). If not required to be
    motivated by a separate animus from the murder itself, a kidnapping capital specification would
    presumptively fail to genuinely narrow the class of murder defendants eligible for the death penalty.
    See 
    id. 1. Ohio
    Supreme Court’s ruling
    The Ohio Supreme Court determined that the prosecutor had introduced proof that one of
    Snipes’s legs had been tied to the bed, and had shown that this restraint was effected while she was
    Nos. 04-4138/4185/4243                       Hartman v. Bagley                                Page 18
    alive. 
    Hartman, 754 N.E.2d at 1162
    . Regarding the separate animus requirement, the Court stated
    that
    the test to determine whether the kidnapping was committed with a separate animus
    so as to support a separate conviction is whether the restraint or movement of the
    victim is merely incidental to a separate underlying crime or, instead, whether it has
    a significance independent of the other offense.
    
    Id. (quotation marks
    omitted). Applying this test, the Court concluded: “The evidence therefore
    shows that Snipes’s kidnapping, i.e., the restraint, was completed prior to her murder and that the
    restraint was not merely incidental to her murder.” 
    Id. Justice Pfeifer
    dissented on this issue. He opined that, although “[i]t is possible to believe
    that a kidnapping occurred,” the record did not establish the kidnapping beyond a reasonable doubt
    because “the alleged kidnapping was in reality a series of actions that were incidental to the crime
    of murder.” 
    Id. at 1183
    (Pfeifer, J. dissenting).
    2.      District court’s ruling
    The district court deemed Hartman’s kidnapping claim to be his “best argument for habeas
    relief,” 
    Hartman, 333 F. Supp. 2d at 666
    , but ultimately concluded that “[a] reasonable juror could
    well find that Hartman’s restraint of Winda Snipes was motivated by a different animus than the
    animus motivating the murder.” 
    Id. at 669.
    Reviewing Ohio law, the district court concluded that
    two questions were significant for determining the existence of a separate animus: “(1) was the
    restraint prolonged, the confinement secretive, or the movement substantial to show a significance
    independent of the other offense, and (2) did the asportation or restraint of the victim subject the
    victim to a substantial increase in risk of harm separate and apart from that involved in the
    underlying crime?” 
    Id. The district
    court’s analysis focused on the second prong in determining that the tying of
    Snipes’s leg to the bed exposed her to a substantial increase in the risk of harm separate from that
    involved in the murder. First, the court noted that tying Snipes’s leg “substantially increased her
    risk of harm of assault and rape.” 
    Id. Second, the
    court held that the restraint in question “only
    marginally increased her risk of the type of murder she suffered—strangulation and a slit throat.”
    The court based this latter conclusion, in part, on the coroner’s testimony that Snipes died quickly
    after her throat was slit. 
    Id. Were the
    restraint intended to facilitate this form of murder, the court
    reasoned, Hartman would have restrained Snipes’s upper extremities as well in light of the forensic
    evidence demonstrating that she struggled with her arms. 
    Id. at 669
    n.15. Furthermore, the court
    determined that “Snipes’ small size, only 5 feet, 2 inches tall with a weight of 128 pounds, suggests
    that binding her to the bed was neither necessary to carry out the murder nor likely associated with
    the murder.” 
    Id. at 669
    (citation omitted).
    3.      Our review
    Hartman preserved this claim for habeas review by raising it in his direct appeal. As a result,
    the Ohio Supreme Court’s determination that the evidence was sufficient to support the kidnapping
    capital specification and separate kidnapping conviction must be upheld unless it is contrary to, or
    an unreasonable application of, clearly established federal law. Evidence is constitutionally
    sufficient if, when viewed in the light most favorable to the government, “any rational trier of fact
    could have found the essential elements of the crime beyond a reasonable doubt.” Jackson v.
    Virginia, 
    443 U.S. 307
    , 319 (1979) (emphasis in original).
    As the Ohio Supreme Court and the district court concluded, the evidence that Hartman
    restrained Snipes by forcibly tying one of her legs to the bed for some period of time while she was
    Nos. 04-4138/4185/4243                       Hartman v. Bagley                                Page 19
    alive sufficed to establish the standard elements of kidnapping. Consequently, we turn to the central
    issue of whether the evidence was constitutionally sufficient to support a finding that Hartman
    possessed an animus to commit the kidnapping that was separate and apart from that motivating the
    underlying murder.
    The “separate animus” requirement under Ohio law does not demand that a defendant
    possess an animus to kidnap exclusive of an animus to commit other crimes; instead, it simply
    requires that the kidnapping animus exist separately. See State v. Logan, 
    397 N.E.2d 1345
    , 1351-52
    (Ohio 1979) (framing the primary issue in determining the existence of a separate kidnapping
    animus as whether “the restraint or movement of the victim” has “significance independent of the
    other offense”). Evidence of substantial movement of the victim, for example, can satisfy the
    separate-animus requirement even if the perpetrator may have ultimately intended to commit
    additional crimes against the victim. See State v. Jells, 
    559 N.E.2d 464
    , 475 (Ohio 1990) (finding
    that the evidence supported a separate kidnapping animus where the defendant kidnapped a victim
    by forcing her and her son into a van and driving off, and then murdered her by beating her to death
    either during the course of the drive or after arriving at a junkyard). Similarly, a separate animus
    has been found where the defendant restrains the victim in order to facilitate inflicting substantial
    harm separate and apart from that associated with murder (such as terrorizing or torturing a victim),
    even if the defendant may have ultimately intended to murder the victim. See State v. Seiber, 
    564 N.E.2d 408
    , 420 (Ohio 1990) (finding that the evidence supported a separate animus for kidnapping
    based on a substantially increased risk of harm where the defendant threatened and terrorized
    various bar patrons before finally murdering one of them). The kidnapping in both Jells and Seiber
    was not merely incidental to the murder; instead, the restraint was found to have a separate purpose
    that genuinely distinguished it from the restraint typically inherent in the crime of murder.
    In the present case, Snipes was found with one leg bound by pantyhose to the bed and a gag
    over her mouth. According to the medical examiner, Snipes had been bound while she was still
    alive. The medical examiner’s report stated that, in addition to numerous nonfatal stab wounds,
    Snipes suffered significant blunt-force trauma to her face and eyes, indicating a beating. (Although
    the Ohio Supreme Court and the district court speculated as to whether Snipes had been raped based
    on the semen discovered in Snipes’s body, Hartman accurately points out that the medical examiner
    found no evidence of forced entry. Combined with the admitted consensual relationship between
    Hartman and Snipes, the evidence does not clearly establish that a rape occurred or that the restraint
    facilitated a rape.)
    In spite of the clear evidence that Snipes was restrained, Justice Pfeifer dissented from the
    Ohio Supreme Court’s majority opinion and concluded that the increased-risk-of-harm factor of the
    separate-animus inquiry was not sufficiently established. His conclusion, however, appears to derive
    primarily from his expansive interpretation of the harm involved in the underlying crime of murder.
    He states that “the alleged kidnapping was in reality a series of actions that were incidental to the
    crime of murder.” 
    Hartman, 754 N.E.2d at 1183
    (Pfeifer, J., dissenting). If the harm involved in
    the underlying crime of murder is confined to acts that purposefully cause the death of another,
    however, the separate, extraordinary harms to which Snipes was subject by virtue of her restraint
    establish a separate kidnapping animus. The disagreement among the justices thus centered on
    whether inflicting beatings and numerous patently nonlethal stab wounds amounted to harm
    “separate and apart” from that associated with the murder.
    We believe that the district court’s focus both on Snipes’s diminutive size compared with
    Hartman’s and on the rapidity of her death following the slitting of her throat resolve the debate in
    favor of the Ohio Supreme Court’s majority opinion. See 
    Hartman, 333 F. Supp. 2d at 669
    . There
    is little reason to believe that Hartman needed to restrain Snipes in order to inflict the harm
    associated with her murder, but strong reason to conclude that the restraint was intended to facilitate
    the infliction of the additional nonlethal harms apparent from the forensic evidence. Cf. State v.
    Nos. 04-4138/4185/4243                       Hartman v. Bagley                                 Page 20
    Adams, 
    817 N.E.2d 29
    , 51 (Ohio 2004) (finding no separate animus where the victim had not been
    bound or restrained in any way other than what was “necessary” to commit the underlying offenses).
    Based on the evidence presented, we conclude that a reasonable juror could find beyond a
    reasonable doubt that Hartman’s restraint of Snipes subjected her to an increased risk of the harm
    associated with being beaten and terrorized that was separate and apart from the harm involved in
    being murdered. Had the much-larger Hartman intended solely to murder Snipes, there is no reason
    to believe that the leg restraint and gag would have been necessary. The Ohio Supreme Court’s
    determination that sufficient evidence supported a finding that Hartman possessed a separate animus
    to kidnap Snipes was therefore not contrary to or an unreasonable application of clearly established
    federal law. See 
    Jackson, 443 U.S. at 319
    .
    F.      Ineffective assistance of former habeas counsel
    In addition to the issues listed in the COA, Hartman attempts to raise in this appeal the issue
    of the allegedly ineffective assistance of his former habeas counsel. Hartman previously sought a
    COA regarding this claim, but both the district court and this court denied that request. This court
    also denied his petition to rehear that particular COA request en banc. Because the COA granted
    for this appeal covers only the issues set forth above, and because we have previously determined
    that Hartman’s claim regarding his former habeas counsel is without merit, we decline to further
    address it here.
    III. CONCLUSION
    For all of the reasons set forth above, we AFFIRM the judgment of the district court.
    Nos. 04-4138/4185/4243                               Hartman v. Bagley                                        Page 21
    _______________________________________________
    CONCURRING IN PART, DISSENTING IN PART
    _______________________________________________
    CLAY, Circuit Judge, concurring in part and dissenting in part. With the exception of Parts
    II.B and II.C, I join in the majority’s well-reasoned opinion. With respect to Petitioner’s claim of
    ineffective assistance of counsel at the sentencing phase, I concur in the majority’s analysis of
    procedural default and its conclusion that Petitioner established cause to excuse the procedural
    default. However, I respectfully dissent from the majority opinion inasmuch as it denies Petitioner’s
    ineffective assistance of counsel claim on the merits. In my view, Petitioner’s counsel performed
    ineffectively at the sentencing phase, thereby violating Petitioner’s Sixth Amendment Right to
    Counsel. Correspondingly, I believe Petitioner has shown prejudice to excuse procedural default
    of this claim. See Coleman v. Thompson, 
    501 U.S. 722
    , 750 (1991) (a petitioner must show cause
    and prejudice to obtain federal habeas relief on a procedurally defaulted claim); Joseph v. Coyle, 
    469 F.3d 441
    , 462-63 (6th Cir. 2006) (“[E]stablishing Strickland prejudice likewise establishes prejudice
    for purposes of cause and prejudice.”). On the matter of acquittal-first jury instructions, I also
    dissent on the belief that the Ohio Supreme Court’s decision runs contrary to clearly established
    Supreme Court precedent on jury instructions in capital cases. I would therefore vacate Petitioner’s
    death sentence and remand for a new sentencing phase trial.
    Like the majority, I would review Petitioner’s ineffective assistance claim de novo because
    the Ohio state courts failed to adjudicate this claim on the merits. See Wiggins v. Smith, 
    539 U.S. 510
    , 528-31 (2003); McKenzie v. Smith, 
    326 F.3d 721
    , 726-27 (6th Cir. 2003); Clinkscale v. Carter,
    
    375 F.3d 430
    , 436 (6th Cir. 2004). Petitioner contends that trial counsel “fail[ed] to thoroughly
    investigate his background and mental health history for potential1mitigating evidence,” and failed
    to present sufficient evidence in mitigation. (Pet.’s Br. at 11, 13) Reviewing this claim de novo,
    I would grant Petitioner habeas relief.
    In an appendix to his Petition to Vacate, Petitioner attached a May 13, 1998 evaluation of
    Petitioner conducted by a clinical and forensic psychologist, James W. Siddall, Ph.D., wherein Dr.
    Siddall identified “potential mitigating circumstances pursuant to Ohio Revised Code
    [§] 2929.04(B).” (J.A. at 1332) The Siddall Report set forth Petitioner’s social history, including
    instability in his living situation, adjustment problems at home and at school, physical abuse at the
    hands of a step-father, alleged sexual abuse at the hands of a step-mother, the death of his father in
    1994, a history of substance abuse and alcoholism, and time as a runaway living homeless on the
    streets. Moreover, the Siddall Report assessed Petitioner’s mental status and personality, concluding
    that Petitioner suffered from “a mixed personality disorder with obsessive-compulsive, narcissistic,
    and antisocial features.” (Id. at 1337) It went on to characterize individuals with mixed personality
    disorder as typically “stubborn, self-centered, low in frustration tolerance, and fail[ing] to conform
    to social norms,” (id.) and noted that “[u]nder the influence of disinhibiting substances, episodes of
    irritability, hostility, aggression, and loss of control may be observed.” (Id. at 1338)
    1
    Petitioner also challenges counsel’s effectiveness inasmuch as counsel conceded in his opening statement
    “there was nothing they could do to reduce the blame for this crime,” counsel failed to object to the prosecutor’s
    improper arguments, and counsel failed to object to the state’s use of certain victim impact evidence. However, this
    Court granted Petitioner’s COA on a more limited scope, certifying the question whether counsel performed ineffectively
    “by not conducting a sufficient investigation into mitigating factors and not presenting significant evidence during the
    sentencing phase.” (Order at 2 (Aug. 10, 2005)) Accordingly, claims of ineffective assistance on these alternative bases
    are not before this Court. See Bugh v. Mitchell, 
    329 F.3d 496
    , 502 n.1 (6th Cir. 2003) (citing Valentine v. Francis,

    Nos. 04-4138/4185/4243                               Hartman v. Bagley                                         Page 22
    Petitioner’s trial counsel did not call Dr. Siddall to testify in the penalty phase, nor did he
    introduce the Siddall Report into evidence. Instead, the entire case in mitigation consisted of
    testimony from   Petitioner’s sister, Rhea Wolpert (“Ms. Wolpert”), and aunt, Arletta Hartman (“Ms.
    Hartman”).2 Their testimony largely tracked the mitigating factors contained in the Siddall Report.
    Ms. Wolpert spoke about Petitioner’s difficulty adjusting as a child, his unstable family situation,
    his time as a runaway, his involvement with drugs and alcohol, and his family’s history of
    alcoholism. She testified that while Petitioner lived with her, he got himself a job, “was a hard
    worker,” and helped contribute (both financially and in terms of house work) to the household, but
    that even then she noticed his problems with alcohol. (J.A. at 708-09) Ms. Wolpert further stated
    that, in her experience, Petitioner had only “a little” difficulty with authority and was “[n]o[] more
    [rebellious] than any other child.” (Id. at 711-12)
    Ms. Hartman testified that she agreed to care for Petitioner when he was eight because
    Petitioner was experiencing “discipline problems and problems with his stepfather” at home. (J.A.
    at 724) She indicated that Petitioner behaved hyperactively and had some difficulty adjusting both
    socially and academically at first, and that later he grew rebellious, lying and stealing apparently so
    Ms. Hartman would send him back to his mother. Ms. Hartman additionally reported on Petitioner’s
    episodes as a runaway, his involvement in theft, and his time served in a juvenile detention center.
    Further, she testified to his theft of a car, his apparent selling of drugs, alcoholism, and two
    additional stays in California group homes. Finally, Ms. Hartman testified that Petitioner took
    action to make amends with his father and step-mother, voluntarily turned himself in to the
    California group home that he had improperly left at an earlier time, and – while at the group home
    – earned his GED and got a job. As stated previously, the testimony of Ms. Wolpert and Ms.
    Hartman constitutes the entirety of the case Petitioner’s counsel put forth in mitigation. Critically,
    Petitioner’s counsel proffered no evidence of physical abuse by Petitioner’s step-father or of sexual
    abuse by Petitioner’s step-mother, and insufficient evidence   of genetic alcoholism for the trial judge
    to allow reference to it in Petitioner’s ‘Exhibit U.’3 (Id. at 751-52)
    Defendant must show both (1) deficient performance of counsel; and (2) that counsel’s
    deficient performance prejudiced the defense, thereby rendering the trial fundamentally unfair.
    Strickland v. Washington, 
    466 U.S. 668
    , 687 (1984). Counsel performs deficiently where his
    “representation f[a]ll[s] below an objective standard of reasonableness.” 
    Id. at 688.
    Objectively
    reasonable representation is properly measured with reference to “prevailing professional norms”
    and the inquiry takes into account all circumstances at the time of the conduct. 
    Id. at 688-89.
    Appellate courts review counsel’s performance with great deference. To satisfy the second prong
    of the inquiry, a “defendant [must] affirmatively prove prejudice” by showing “a reasonable
    probability that, but for counsel’s unprofessional errors, the result of the proceeding would have
    been different.” 
    Id. at 693-94.
    The probability need only be so great as to “undermine confidence
    in the outcome.” 
    Id. at 694.
    Failure to satisfy either prong of the inquiry is dispositive.
    In my view, trial counsel failed to provide objectively reasonable representation at the
    mitigation phase. See 
    Strickland, 466 U.S. at 688
    . “[C]ounsel has a duty to make reasonable
    investigations or to make a reasonable decision that makes particular investigations unnecessary.”
    2
    As the majority acknowledges, Ms. Wolpert, who is eleven years older than Petitioner, moved away from
    home when Petitioner was merely five years old. Until Petitioner’s late teens, when he lived with Ms. Wolpert for a few
    years, Petitioner had little contact with Ms. Wolpert. As a result, almost the entire body of Ms. Wolpert’s testimony
    came not from first-hand knowledge of Petitioner’s life and activities, but from stories relayed to her by their mother.
    Ms. Hartman lived with and cared for Petitioner for a similarly brief period of time (three and one-half years).
    3
    Exhibit U was a chart prepared by Petitioner’s counsel setting forth mitigating factors that initially included
    the step-father’s abusiveness and genetic alcoholism. In response to Respondent’s objection to the exhibit’s
    admissibility, the trial judge required Petitioner to redact references to both the physical abuse and alcoholism.
    Nos. 04-4138/4185/4243                                 Hartman v. Bagley                                          Page 23
    
    Id. at 691.
    Accordingly, we must consider “whether counsel conducted a reasonable investigation
    of Defendant’s background.” Spisak v. Mitchell, 
    465 F.3d 684
    , 707 (6th Cir. 2006). As an aid “to
    determining what is reasonable,” courts have looked to the American Bar Association Guidelines.
    Rompilla v. Beard, 
    545 U.S. 374
    , 387 (2005) (citing 
    Wiggins, 539 U.S. at 524
    ). The ABA Standards
    for Criminal Justice provide that:
    [t]he lawyer . . . has a substantial and important role to perform in raising mitigating
    factors both to the prosecutor initially and to the court at sentencing. This cannot
    effectively be done on the basis of broad general emotional appeals or on the strength
    of statements made to the lawyer by the defendant. Information concerning the
    defendant’s background, education, employment record, mental and emotional
    stability, family relationships, and the like, will be relevant, as will mitigating
    circumstances surrounding the commission of the offense itself. Investigation is
    essential to the fulfillment of these functions.
    1 ABA Standards for Criminal Justice 4-4.1 (1982 Supp.).
    “In assessing the reasonableness of an attorney’s investigation, . . . a court must consider not
    only the quantum of evidence already known to counsel, but also whether the known evidence
    would lead a reasonable attorney to investigate further.” 
    Wiggins, 539 U.S. at 527
    . Trial counsel
    apparently possessed at least some of Petitioner’s mental health records and his criminal records.
    Beyond that, the record reflects that trial counsel’s mitigation phase investigation involved
    consultation with Dr. Siddall, and discussions with Ms. Wolpert and Ms. Hartman. Dr. Siddall
    evaluated Petitioner and prepared a report to assist counsel in identifying potential mitigating factors
    for presentation at the sentencing phase. Dr. Siddall interviewed Petitioner personally and
    administered several psychological and personality assessment tests. Although the Siddall Report
    identified several pathways for further investigation, it does not appear that trial counsel pursued
    those paths.
    Rather, from the record before us, it appears that trial counsel unreasonably limited his
    investigation, all but foreclosing consideration of three potential mitigating factors. First, the Siddall
    Report clearly identified genetic alcoholism as a factor in mitigation. Ms. Wolpert proffered vague
    testimony about her family’s4 history of alcoholism and Petitioner’s personal struggles with alcohol
    abuse, as did Ms. Hartman. Not surprisingly, the trial judge found this testimony insufficient to
    establish genetic alcoholism and, accordingly, redacted that mitigating factor from an exhibit
    prepared by Petitioner’s counsel to guide the jury’s deliberations. Consistent with the ABA
    Guidelines,
    [r]ecords should be requested concerning not only the client, but also his parents,
    grandparents, siblings, and children. A multi-generational investigation frequently
    discloses significant patterns of family dysfunction and may help . . . underscore the
    hereditary nature of a particular impairment.
    Hamblin v. Mitchell, 
    354 F.3d 482
    , 487 n.2, 488 (6th Cir. 2003) (quoting ABA Guidelines for the
    Appointment & Performance of Def. Counsel in Death Penalty Cases ¶ 10.7, at 80-83 (2003)) (citing
    the “2003 ABA Guidelines . . . because they are the clearest exposition of counsel’s duties at the
    penalty phase . . . , duties that were recognized by this court as applicable to the 1982 trial of the
    4
    Notably, when asked about Petitioner’s drinking, Ms. Wolpert responded, “He was involved a little bit.” (J.A.
    at 709) Counsel’s exploration of genetic alcoholism consisted of two questions: first, “there’s alcoholism in your family;
    is that correct;” and second, “[Petitioner] has been around alcoholics and alcohol all of his life, if you’re aware of that?”
    (Id. at 712) In each case, Ms. Wolpert gave brief, lukewarm affirmative answers. Ms. Hartman’s testimony recounted
    an episode where Petitioner was hospitalized as an adolescent following a “chuck-a-lucking” contest. (Id. at 738)
    Nos. 04-4138/4185/4243                              Hartman v. Bagley                                        Page 24
    defendant in Glenn v. Tate”). A “reasonably competent attorney” would have pursued stronger
    evidence of genetic alcoholism. See 
    Wiggins, 539 U.S. at 534
    .
    Second, according to the Siddall Report, Petitioner suffered physical abuse at the hands of
    his step-father, and sexual abuse at the hands of his step-mother. As the majority indicates,
    Petitioner’s claims of physical and sexual abuse were not corroborated by Petitioner’s family
    members during interviews with Dr. Siddall. Yet, Dr. Siddall’s investigation was not exactly
    searching itself. In fact, the report indicates that Dr. Siddall relied on background information
    summarizing Petitioner’s “criminal justice involvement, mental health treatment, and the
    circumstances of the instant offense,” two meetings with Petitioner himself, and telephone
    interviews with Petitioner’s mother and Ms. Hartman. (J.A. at 1332) The fact that Petitioner’s
    mother and Ms. Hartman did not corroborate Petitioner’s claims of childhood abuse 5does not
    unequivocally mean that trial counsel, upon investigation, would find no record of abuse. On the
    basis of this very small body of evidence, when coupled with the often secretive treatment of abuse,
    a reasonably competent attorney could not simply conclude “that further investigation would have
    been fruitless.” See 
    Wiggins, 539 U.S. at 525
    . To the extent that Dr. Siddall partially attributed
    Petitioner’s personality disorder to “instability and abuse in his home environment,” (id. at 1338),
    trial counsel had even greater reason to investigate the alleged instances of abuse.
    Third, Dr. Siddall concluded that Petitioner suffered from mixed personality disorder – a
    condition that, when combined with “disinhibiting substances,” can lead to “episodes of irritability,
    hostility, aggression, and loss of control.” (J.A. at 1338) As the Report reflects, Dr. Siddall further
    concluded that instability and abuse at home contributed to Petitioner’s mixed personality disorder.
    In my view, Dr. Siddall’s conclusion would prompt a reasonable attorney to investigate more fully
    Petitioner’s mental and emotional stability over time, for example, by requesting his school records,
    records from juvenile detention facilities and group homes, or from any medical professionals or
    counselors. On the record before us, it appears that trial counsel did not conduct additional
    investigation into the development and existence of a personality disorder. “Our Court’s precedents
    . . . make clear that conducting a partial, but ultimately incomplete, mitigation investigation does not
    satisfy Strickland’s requirements.” Dickerson v. Bagley, 
    453 F.3d 690
    , 695 (6th Cir. 2006).
    Aside from his insufficient investigation, trial counsel failed to introduce evidence within
    his control. Specifically, counsel failed to introduce evidence of Dr. Siddall’s conclusion that
    Petitioner suffered from “a mixed personality disorder with obsessive-compulsive, narcissistic, and
    antisocial features” which left him prone to “episodes of irritability, hostility, aggression, and loss
    of control” when under the influence. (See J.A. at 1337-38) Dr. Siddall’s report additionally
    indicated that Petitioner’s mixed personality disorder and propensity to substance abuse were
    “compounded by instability and abuse in his home environment.” (Id. at 1339). What is more, the
    Siddall Report raises the implication that counsel had in his possession some evidence of abuse. The
    Report quotes the findings of psychologists at the New Mexico Youth Diagnostic and Development
    Center that Petitioner “‘presented symptoms characteristic of children who had been abused
    including poor self-esteem, difficulty with authority, and rebellious behavior.’” (Id. at 1339) These
    findings apparently came from the mental health records in trial counsel’s possession which, of
    course, counsel did not introduce at the sentencing phase of Petitioner’s trial.
    The majority finds that Petitioner’s trial counsel likely made strategic choices in presenting
    Petitioner’s case in mitigation “through the more sympathetic lens of family members’ testimony,”
    and in omitting reference to less helpful portions of the Siddall Report. I do not disagree that, by
    presenting mitigating evidence through Ms. Wolpert and Ms. Hartman, trial counsel humanized
    5
    In fact, the Siddall Report suggests that mental health records apparently in counsel’s possession described
    Petitioner as presenting “symptoms characteristic of children who had been abused.” (J.A. at 1339)
    Nos. 04-4138/4185/4243                       Hartman v. Bagley                                 Page 25
    Petitioner in a way that Dr. Siddall’s testimony could not. Yet, by confining the case in mitigation
    to their testimony, trial counsel similarly limited the evidence of genetic alcoholism and abuse put
    before the jury. In doing so, counsel did not foreclose reference to less sympathetic elements of
    Petitioner’s background and history, since counsel himself elicited such testimony on direct
    examination of Ms. Wolpert and Ms. Hartman. Cf. Darden v. Wainwright, 
    477 U.S. 168
    , 186 (1986)
    (counsel not ineffective where limited mitigation case was designed to foreclose rebuttal evidence
    of petitioner’s prior convictions); Clark v. Mitchell, 
    425 F.3d 270
    , 286 n.6 (6th Cir. 2005) (finding
    counsel’s representation not deficient, in part, because it was likely that “counsel made a strategic
    decision to limit testimony about [the petitioner’s] past in order to prevent ‘opening-the-door’ to
    evidence of [his] criminal background”). Ms. Wolpert readily described Petitioner’s efforts to work
    hard and contribute to the household while he lived with her, and testified that Petitioner had only
    “a little” difficulty with authority as a child. (J.A. at 711-12) Similarly, Ms. Hartman testified that
    Petitioner had taken steps to mend his relationship with his father and step-mother, to make good
    at the California group home from which he previously absconded, and to earn his GED and hold
    down a job. In my view, the contention that counsel made strategic choices to shape this case in
    mitigation “resembles more a post hoc rationalization of counsel’s conduct than an accurate
    description of their deliberations prior to sentencing.” See 
    Wiggins, 539 U.S. at 526-27
    (emphasis
    in original). At any rate, “virtually unchallengeable” strategic choices follow “thorough
    investigation of law and facts relevant to plausible options.” 
    Strickland, 466 U.S. at 690
    (emphasis
    added). Absent thorough investigation of plausible leads, I would not find that Petitioner’s trial
    counsel performed effectively.
    Although not dispositive, the numbers in this case paint a compelling picture. Dr. Siddall’s
    report identified ten potential mitigating factors. Trial counsel received the report a mere five days
    before Petitioner’s mitigation hearing began. At the hearing, counsel put forth the testimony of two
    witnesses, and admitted one summary exhibit into evidence. The entirety of Petitioner’s case in
    mitigation spans approximately 40 pages of transcript. Trial counsel’s closing argument covered
    a total of ten pages in the transcript, culminating in “a two and a half page story about the ancient
    Greek philosopher and orator Aeschylus, the conclusion of which was counsel telling the jury ‘the
    answer is in your hand.’” (Pet.’s Br. at 21 n.9; see also J.A. at 774) Qualitatively and quantitatively,
    trial counsel’s performance fell below “prevailing professional norms.” See 
    Strickland, 466 U.S. at 688
    -89.
    Additionally, Petitioner must show he suffered prejudice as a result of trial counsel’s
    deficient performance. Petitioner need only show “a reasonable probability that, but for counsel’s
    unprofessional errors, the result of the proceeding would have been different.” 
    Strickland, 466 U.S. at 693-94
    . The probability need only be so great as to “undermine confidence in the outcome.” 
    Id. at 694.
    “In assessing prejudice, [this Court] reweigh[s] the evidence in aggravation against the
    totality of available mitigating evidence.” 
    Wiggins, 529 U.S. at 534
    . “Mitigating evidence unrelated
    to dangerousness may alter the jury’s selection of penalty, even if it does not undermine or rebut the
    prosecution’s death-eligibility case.” Williams v. Taylor, 
    529 U.S. 362
    , 398 (2000). Ultimately,
    “the ‘prejudice’ prong is satisfied if ‘there is a reasonable probability that at least one juror would
    have struck a different balance.’” 
    Hamblin, 354 F.3d at 493
    .
    On appeal, Petitioner relies on counsel’s failure to introduce the Siddall Report – or to have
    Dr. Siddall testify – to show prejudice. Either through the report itself or through questioning Dr.
    Siddall, counsel could have elicited testimony on Petitioner’s personality disorder, the way his social
    and familial history likely contributed to the disorder, and the way the disorder (coupled with his
    alcoholism) rendered him incapable of controlling his impulses. This, of course, is critically
    important inasmuch as impulse control bears on Petitioner’s culpability. Cf. California v. Brown,
    
    479 U.S. 538
    , 545 (1987) (O’Connor, J., concurring) (noting that a “defendant[] who commit[s]
    criminal acts that are attributable to a disadvantaged background, or to emotional and mental
    problems, may be less culpable than defendants who have no such excuse”). In fact, the Ohio death
    Nos. 04-4138/4185/4243                               Hartman v. Bagley                                         Page 26
    penalty statute makes “mental disease or defect” a mitigating factor. See Ohio Rev. Code
    § 2929.04(B)(3).6 Thus, had the jury known of Petitioner’s apparent personality disorder, and had
    counsel investigated and adduced evidence of genetic alcoholism and abuse, “there is a reasonable
    probability that at least one juror would have struck a different balance,” finding Petitioner less
    culpable and sentencing him to life in prison, not death. See 
    Wiggins, 539 U.S. at 537
    ; see also
    
    Williams, 529 U.S. at 395-98
    (finding prejudice from counsel’s failure to investigate and introduce
    evidence which “might well have influenced the jury’s appraisal of his moral culpability”).
    Moreover, “Petitioner . . . has the kind of troubled history . . . relevant to assessing a
    defendant’s moral culpability.” 
    Wiggins, 539 U.S. at 535
    (citing Penry v. Lynaugh, 
    492 U.S. 302
    ,
    319 (1989)). Through Dr. Siddall’s report, or his testimony, the jury would have received a more
    comprehensive understanding of Petitioner’s social history. Trial counsel’s limited examination of
    Ms. Wolpert – Petitioner’s much older and distant sister – and Ms. Hartman did not sufficiently
    explore Petitioner’s “troubled history” of abuse, alcoholism, and (briefly) homelessness. See Carter
    v. Bell, 
    218 F.3d 581
    , 596-97 (6th Cir. 2000) (failure to investigate unstable childhood and history
    of violence); Greer v. Mitchell, 
    264 F.3d 663
    , 678 (6th Cir. 2001) (counsel knew of and failed to
    investigate family history of alcoholism, violence, foster care, and incarceration); cf. Smith v.
    Mitchell, 
    348 F.3d 177
    , 204 (6th Cir. 2003) (finding no prejudice where “trial counsel presented five
    witnesses at mitigation, and its principal witness . . . presented a comprehensive picture of [the
    petitioner’s] family, social, psychological background, based upon extensive review of ‘[n]umerous
    sources of information,’ which included not only psychological tests, but also interviews, hospital
    records, school reports, and social services records”).
    Dr. Siddall’s testimony on these mitigating factors would differ both “in strength and subject
    matter . . . from the evidence actually presented at sentencing.” See Hill v. Mitchell, 
    400 F.3d 308
    ,
    319 (6th Cir. 2005). The record here reflects that trial counsel put forth insufficient evidence of
    genetic alcoholism, and no evidence of physical and sexual abuse. Cf. 
    Smith, 348 F.3d at 200
    (finding no prejudice where “virtually all of the mitigating elements that [the petitioner]
    complain[ed] of were presented via [the mitigation expert’s] testimony and her mitigation report”);
    
    Hill, 400 F.3d at 317
    (finding evidence cumulative where “most of the information” to be conveyed
    “was included in the nine psychological reports submitted in the penalty and mitigation phases”).
    Therefore, stronger evidence of genetic alcoholism, or any evidence of abuse, put forth either
    through Dr. Siddall’s testimony or more in depth examination of Ms. Wolpert and Ms. Hartman
    would not be “merely cumulative,” and could thus support a finding of prejudice. Cf. Broom v.
    Mitchell, 
    441 F.3d 392
    , 410 (6th Cir. 2006) (“[F]ailure to present additional mitigating evidence that
    is ‘merely cumulative’ of that already presented does not rise to the level of a constitutional
    violation.”). Finally, above and beyond the evidence at counsel’s disposal, a thorough investigation
    of the mitigating factors identified by Dr. Siddall would likely have revealed further evidence of
    genetic alcoholism or abuse. Thus, Petitioner’s trial counsel rendered ineffective assistance, falling
    short of the requirements of the Sixth Amendment.
    I also disagree with the majority’s conclusion on Petitioner’s acquittal-first jury instruction
    claim. The Ohio Supreme Court did consider this claim on the merits albeit, as the majority
    acknowledges, without reference to federal law. Accordingly, for purposes of this dissent, I limit
    my review in accordance with the Anti-Terrorism and Effective Death Penalty Act (AEDPA). 28
    U.S.C. § 2254(d); cf. 
    Wiggins, 539 U.S. at 529-31
    ; 
    McKenzie, 326 F.3d at 726-27
    ; 
    Clinkscale, 375 F.3d at 436
    ; but see Danner v. Motley, 
    448 F.3d 372
    , 376 (6th Cir. 2006) (reviewing de novo where
    the state court considered petitioner’s federal constitutional claim on the merits under state law).
    6
    The statute directs the fact finder to consider “[w]hether, at the time of committing the offense, the offender,
    because of a mental disease or defect, lacked substantial capacity to appreciate the criminality of the offender’s conduct
    or to conform the offender’s conduct to the requirements of the law.” Ohio Rev. Code § 2929.04(B)(3).
    Nos. 04-4138/4185/4243                              Hartman v. Bagley                                       Page 27
    Since the Ohio Supreme Court did not apply clearly established federal law, the relevant inquiry is
    whether their decision runs “contrary to . . . clearly established [Supreme Court] precedent.”
    
    Williams, 529 U.S. at 405-06
    . Thus, the gravamen of this Court’s review must be whether the Ohio
    Supreme Court’s decision is “diametrically different, opposite in character or nature, or mutually
    opposed” to that precedent. 
    Id. at 406
    (internal quotation marks omitted). In my view, the Ohio
    Supreme Court’s decision on this claim runs contrary to clearly established Supreme Court
    precedent – specifically, Mills v. Maryland, 
    486 U.S. 367
    (1988), and our Circuit precedent in Davis
    v. Mitchell, 
    318 F.3d 682
    (6th Cir. 2003) and Spisak v. Mitchell, 
    465 F.3d 684
    (6th Cir. 2006), cases
    which bear on the inquiry inasmuch as they inform the analysis of acquittal-first jury instructions
    under Mills.
    Pursuant to clearly established Supreme Court precedent, the Eighth and Fourteenth
    Amendments require individualized consideration of relevant mitigating factors before a state may
    impose a penalty of death. Lockett v. Ohio, 
    438 U.S. 586
    , 606 (1978); Eddings v. Oklahoma, 
    455 U.S. 104
    , 110 (1982). The holding in Mills follows from Lockett and Eddings. Mills holds that a
    defendant’s rights under the Eighth and Fourteenth Amendments are violated if
    there is a substantial probability that reasonable jurors, upon receiving the judge’s
    instructions in th[e] case, and in attempting to complete the verdict form as
    instructed, well may have thought they were precluded from considering any
    mitigating evidence unless all 12 jurors agreed on the existence of a particular such
    circumstance.
    
    Mills, 486 U.S. at 384
    . Applying Mills, the Supreme Court subsequently concluded that unanimity
    requirements in capital sentencing schemes “prevent[] the jury from considering . . . any mitigating
    factor that the jury does not unanimously find” prior to imposing a sentence of death and therefore
    violate the Eighth and Fourteenth Amendments. McKoy v. North Carolina, 
    494 U.S. 433

    From Mills flows a line of cases in our Circuit examining so-called “acquittal-first” jury
    instructions.7 As the majority observes, acquittal-first jury instructions encompass “[a]ny instruction
    requiring that a jury must first unanimously reject the death penalty before it can consider a life
    sentence.” 
    Davis, 318 F.3d at 689
    (emphasis added). Acquittal-first instructions implicate the
    Eighth and Fourteenth Amendment inasmuch as they create a substantial probability that the jury
    will impermissibly require unanimity as to mitigating factors. This not only constitutes a
    misapplication of Ohio law, but also spuriously tips the scale in favor of death. Under Davis, an
    acquittal-first instruction “precludes the individual juror from giving effect to mitigating evidence
    and runs afoul of Mills.” 
    Davis, 318 F.3d at 689
    ; see also 
    Spisak, 465 F.3d at 709
    .
    The jury instructions here very clearly constitute acquittal-first jury instructions. They differ
    only slightly from the jury instructions in Davis and Spisak, and in ways even more constitutionally
    questionable. The trial courts in Davis and Spisak framed the issue as follows: “[I]f . . . you find
    that the State failed to prove beyond a reasonable doubt that the aggravating circumstances . . .
    outweigh the mitigating factors, . . . you will then proceed to determine which of [the] possible life
    imprisonment sentences to recommend.” 
    Davis, 318 F.3d at 685
    (alterations added and omitted);
    7
    These cases also followed the Ohio Supreme Court’s decision applying Mills in State v. Brooks, 
    661 N.E.2d 1030
    (Ohio 1996). Several cases in this line consider the issue only in dicta, having found the challenges to the jury
    instructions procedurally defaulted. Scott v. Mitchell, 
    209 F.3d 854
    (6th Cir. 2000) being one of them, I would not
    consider this Court bound to follow it. Further, as the majority acknowledges, Roe v. Baker, 
    316 F.3d 557
    (6th Cir.
    2002) concerned jury instructions dissimilar to those now at hand.
    Nos. 04-4138/4185/4243                                  Hartman v. Bagley                                           Page 28
    see also 
    Spisak, 465 F.3d at 709-10
    . Here, the trial court employed slightly different language:8
    “[I]f . . . you cannot unanimously agree that [the State] proved beyond a reasonable doubt that the
    aggravating circumstances . . . outweigh the mitigating factors, . . . you will then proceed to
    determine which of three possible life imprisonment sentences to impose.” (J.A. at 787-88)
    Although the words chosen for the jury instructions vary between Davis and Spisak on one hand and
    Petitioner’s case on the other, the meaning and effect of the instructions does not. If anything, the
    jury instruction in Petitioner’s case poses an even  greater threat of misleading the jury because it
    reiterates that the jury must act “unanimously.”9
    Additionally, the trial court’s verdict form substantially mirrors the verdict forms in Davis
    and Spisak, further compounding the risk of misleading the jury. What is more, the trial judge here
    dismissed the jury to deliberate with the direction to return a verdict “[w]henever all 12 of you, and
    I repeat, all 12 jurors agree.” (J.A. at 793) Taken together, the inappropriate acquittal-first jury
    instructions, the verdict form, and the trial judge’s statement upon dismissing the jury for
    deliberations raise a reasonable likelihood that the jury applied the instructions in Petitioner’s case
    in such a way as to preclude giving effect to mitigating factors unless unanimously found, thereby
    violating Petitioner’s rights under the Eighth and Fourteenth Amendments. Accordingly, in my
    view, the Ohio Supreme Court’s decision runs contrary to the U.S. Supreme Court’s clearly
    established precedent in Mills.
    Thus, because the trial court gave unconstitutional acquittal-first jury instructions, and
    because Petitioner’s counsel rendered ineffective assistance at the sentencing phase, I would vacate
    Petitioner’s sentence and remand for a new sentencing phase trial.
    8
    At greater length, Petitioner’s penalty phase jury instructions read, in pertinent part, as follows:
    If all 12 members of the jury find by proof beyond a reasonable doubt that the aggravating
    circumstances, as I have defined them, are sufficient to outweigh the mitigating factors, then you must
    return such finding to the Court.
    I instruct you, as a matter of law, that if you make such finding, then you have no choice and
    must make a recommendation to the Court that the sentence of death be imposed on the Defendant [].
    ...
    On the other hand, if after considering all of the evidence raised at trial which is relevant to
    the issues before you, the testimony, other evidence, and the arguments of counsel, you cannot
    unanimously agree that the State of Ohio proved beyond a reasonable doubt that the aggravating
    circumstances, as I have defined them, outweigh the mitigating factors, then you’ll return your
    recommendation reflecting your decision.
    In this event, you will then proceed to determine which of the three possible life
    imprisonment sentences to impose. . . .
    (J.A. at 786-88) (emphasis added)
    9
    More subtly, and perhaps a point more suitably explored by psychologists, the instruction at hand asks the jury
    to consider what the “State proved,” and not what it “failed to prove.” The former, it seems, establishes a threshold
    presumption that the State, in fact, proved its case.
