    OPINION
    _________________
    KAREN NELSON MOORE, Circuit Judge. A Tennessee jury convicted William Glenn
    Rogers of kidnapping, rape, and murder, and imposed a sentence of death. Rogers appeals from
    the denial of his petition for a writ of habeas corpus by the United States District Court for the
    Middle District of Tennessee. On appeal, Rogers raises claims related to sufficiency of the
    evidence and the state’s limitation of evidence and cross-examination, as well as five groups of
    claims of ineffective assistance of counsel at the guilt/innocence, sentencing, and motion-for-a-
    new-trial stages. For the reasons that follow, we affirm the district court’s opinion with respect
    to the guilt/innocence phase of trial. We conclude, however, that Rogers’s counsel rendered
    ineffective assistance at the sentencing phase that makes us doubt whether this phase of trial
    produced a fair result.   We further hold that, in Tennessee, ineffective assistance of post-
    conviction counsel can establish cause to excuse a defendant’s procedural default of a substantial
    claim of ineffective assistance at the motion-for-a-new-trial stage. Accordingly, we AFFIRM in
    part, REVERSE in part, VACATE in part, and REMAND for further proceedings consistent
    with this opinion.
    I. BACKGROUND
    The Tennessee Supreme Court summarized the facts as follows:
    At the guilt phase of the trial, the State presented proof that on July 3,
    1996, nine-year-old Jacqueline (“Jackie”) Beard was playing with her twelve-
    year-old brother, Jeremy Beard, and her eleven-year-old cousin, Michael Carl
    Webber, at a mud puddle near her home in the Cumberland Heights area of
    Clarksville in Montgomery County. The defendant, thirty-four-year-old William
    Glenn Rogers, approached the children and introduced himself as “Tommy
    Robertson.” He said he was an undercover police officer, offered the children
    fireworks, and invited them to go swimming. Jackie went home and told her
    mother, Jeannie Meyer, about the man. Mrs. Meyer took Jackie back to the mud
    puddle to investigate. While the children played with the fireworks, Mrs. Meyer
    talked with Rogers, who continued to identify himself as undercover officer
    Tommy Robertson. After approximately thirty-five minutes, Rogers left in his
    car.
    No. 19-5427                             Rogers v. Mays                                     Page 3
    At around 1:30 p.m. on July 8, 1996, Rogers appeared at the Meyer
    residence asking about a lost key. Jackie was with her mother when Mrs. Meyer
    spoke with Rogers. Rogers was last seen walking down the road toward a nearby
    abandoned trailer. A few minutes later, Mrs. Meyer gave Jackie permission to
    pick blackberries to take to the doctor’s office where Mrs. Meyer had an
    appointment that afternoon. Jackie changed her shorts immediately before
    leaving the house. At 1:55 p.m., Mrs. Meyer was ready to leave and called for
    Jackie but could not find her. At around 2:00 p.m., a neighbor, Mike Smith, saw a
    car matching the description of Rogers’ car leaving the immediate area. Smith
    had seen the same car heading in the direction of the Meyer residence about an
    hour or two earlier. Mrs. Meyer searched the area by car and on foot to no avail.
    Jackie was never seen alive again.
    State v. Rogers (“Rogers II”), 
    188 S.W.3d 593
    , 598 (Tenn. 2006).
    After Beard’s disappearance, the police questioned Rogers. 
    Id. at 599
    . At first, Rogers
    denied seeing Beard that day; later, he said that he accidentally struck her with his car and then
    threw her body off a bridge into the river. Id.; R. 25-5 (Tr. at 127–32) (Page ID #3894–99).
    After the police asked Rogers about a child’s fingerprints in his car, he said that Beard briefly sat
    in his car and spoke with him. Rogers II, 
    188 S.W.3d at 599
    . Throughout police questioning, he
    denied any sexual abuse. 
    Id.
    On November 8, 1996, two deer hunters found Beard’s remains in a wooded area in Land
    between the Lakes, approximately forty-eight miles from her home. 
    Id.
     at 599–600. Her shoes,
    shirt, and shorts were near her remains. 
    Id.
     The shirt was inside out. 
    Id. at 600
    ; R. 25-7 (Tr. at
    231) (Page ID #4376). Later tests revealed sperm heads on the inside of the crotch area of her
    shorts. Rogers II, 
    188 S.W.3d at 600
    .
    At the guilt/innocence phase of trial, the jury convicted Rogers on each of nine counts,
    including one count of first-degree premeditated murder, two counts of first-degree felony
    murder, two counts of aggravated kidnapping, two counts of rape of a child, and two counts of
    criminal impersonation. R. 25-11 (Tr. at 221–22) (Page ID #5132–33).
    No. 19-5427                                    Rogers v. Mays                                            Page 4
    At the penalty phrase, several mitigation witnesses testified.                   The most significant
    mitigation witness was Rogers’s sibling Sam,1 who testified that their stepfather “often”
    “slapp[ed],” “hit[]” and “punch[ed]” them, starting from the time that Rogers was four or five
    years old. R. 25-13 (Tr. at 112–13, 138–39) (Page ID #5383–84, 5409–10). Sam explained that
    Rogers was often chained to the bed, for up to days on end. 
    Id.
     at 119–22 (Page ID #5390–93).
    If Rogers soiled the bed or his pants, their stepfather would rub Rogers’s face in the soiled pants
    or mattress. 
    Id.
     at 124–25, 130 (Page ID #5395–96, 5401). Their stepfather would also lock
    himself and Rogers in the bathroom, and Sam believed that he was forcibly giving Rogers
    enemas. 
    Id.
     at 133–36 (Page ID #5404–07). Additional family members and other lay witnesses
    also briefly testified that Rogers was abused. Three expert witnesses also testified. Cecille Guin,
    a social worker, testified in general terms about the violent and abusive conditions at the
    Louisiana Training Institute (LTI), an institution at which Rogers had been confined. 
    Id.
     at 119–
    24 (Page ID #5777–82). Psychologist Tom Neilson testified that he had diagnosed Rogers with
    posttraumatic stress disorder, which resulted from the trauma he experienced, depressive
    disorder not otherwise specified, dissociative disorder not otherwise specified, and a personality
    disorder not otherwise specified with antisocial and borderline features. R. 25-14 (Tr. at 287–
    309) (Page ID #5559–81). Psychiatrist Keith Caruso testified that Rogers met “diagnostic
    criteria for anti-social personality disorder and for border line personality disorder.” R. 25-16
    (Tr. at 149–50) (Page ID #5813–14).
    The jury sentenced Rogers to death. R. 25-17 (Tr. at 38) (Page ID #5983). It found four
    aggravating circumstances: (1) the defendant was previously convicted of one or more felonies
    that involve the use of violence; (2) the murder was committed with the purpose of avoiding,
    interfering with, or preventing a lawful arrest or prosecution; (3) the murder was committed
    against a person younger than twelve and the defendant was at least eighteen; and (4) the murder
    was knowingly committed while the defendant had a substantial role in committing or attempting
    to commit, or was fleeing after having a substantial role in committing, or attempting to commit,
    rape or kidnapping. 
    Id.
     at 36–37 (Page ID #5981–82); see also 
    Tenn. Code Ann. § 39-13-204
    (i)
    1The   state’s brief, state-court decisions, and district-court decision all refer to Sam as Mildred Rogers,
    which was Sam’s prior name. Sam has since changed their name to Samuale Danielle Roger (no “s”). R. 25-13 (Tr.
    at 90) (Page ID #5361); R. 112-6 (Roger Decl. at 1) (Page ID #13577).
    No. 19-5427                            Rogers v. Mays                                    Page 5
    (1996). The jury unanimously found that these aggravating factors outweighed any mitigating
    factors beyond a reasonable doubt. R. 25-17 (Tr. at 37) (Page ID #5982).
    The trial court denied Rogers’s motion for a new trial. R. 24-5 (Order) (Page ID #1168–
    90).   Rogers appealed, first to the Tennessee Court of Criminal Appeals and then to the
    Tennessee Supreme Court. Both courts affirmed Rogers’s convictions and sentence. State v.
    Rogers (“Rogers I”), No. M2002-01798-CCA-R3-DD, 
    2004 WL 1462649
    , at *1 (Tenn. Ct.
    Crim. App. June 30, 2004); Rogers II, 
    188 S.W.3d at 598
    .
    Rogers then filed a petition for post-conviction relief. R. 26-7 (Second Am. Pet. for Post-
    Conviction Relief) (Page ID #7755–80). The post-conviction court denied the petition. R. 26-8
    (Order) (Page ID #7863–8056). The Tennessee Court of Criminal Appeals affirmed the denial
    of post-conviction relief. Rogers v. State (“Rogers III”), M2010-01987-CCA-R3-PD, 
    2012 WL 3776675
    , at *1 (Tenn. Crim. App. Aug. 30, 2012). The Tennessee Supreme Court denied
    review. R. 26-19 (Order) (Page ID #10186).
    Rogers filed a habeas petition in federal district court. R. 14 (Am. Pet. for Writ of
    Habeas Corpus) (Page ID #44–139).          The district court denied the petition.     Rogers v.
    Westbrooks (“Rogers IV”), No. 3:13-cv-00141, 
    2019 WL 1331035
     (M.D. Tenn. Mar. 25, 2019).
    Rogers timely appealed. R. 156 (Notice of Appeal) (Page ID #27325–26).
    II. ANALYSIS
    A. Standard of Review
    We review de novo a district court’s decision to grant or deny a writ of habeas corpus.
    Foust v. Houk, 
    655 F.3d 524
    , 533 (6th Cir. 2011). Under the Antiterrorism and Effective Death
    Penalty Act of 1996 (“AEDPA”), a federal court may grant a writ of habeas corpus “with respect
    to any claim that was adjudicated on the merits in State court proceedings” if the state court
    decision “was contrary to, or involved an unreasonable application of, clearly established Federal
    law, as determined by the Supreme Court of the United States” or “was based on an
    unreasonable determination of the facts in light of the evidence presented in the State court
    proceeding.” 
    28 U.S.C. § 2254
    (d). “Where the state court fails to adjudicate a claim on the
    No. 19-5427                              Rogers v. Mays                                     Page 6
    merits, however, AEDPA’s deferential standard of review does not apply.”                 Williams v.
    Anderson, 
    460 F.3d 789
    , 796 (6th Cir. 2006).
    A state-court decision is contrary to clearly established federal law if “the state court
    applies a rule that contradicts the governing law set forth in [the Supreme Court’s] cases” or “if
    the state court confronts a set of facts that are materially indistinguishable from a decision of [the
    Supreme Court] and nevertheless arrives at a result different from [Supreme Court] precedent.”
    Williams v. Taylor, 
    529 U.S. 362
    , 405–06 (2000). A state-court decision unreasonably applies
    clearly established federal law if it “correctly identifies the governing legal rule but applies it
    unreasonably to the facts of a particular prisoner’s case.” 
    Id.
     at 407–08.
    “[C]learly established Federal law . . . refers to the holdings, as opposed to the dicta of
    [Supreme Court] decisions as of the time of the relevant state-court decision.” 
    Id. at 412
    .
    “Although courts of appeals’ decisions do not establish new rules, the court may look to such
    decisions to inform its analysis of whether a legal principle had been clearly established by the
    Supreme Court.” Avery v. Prelesnik, 
    548 F.3d 434
    , 436–37 (6th Cir. 2008).
    B. Exhausted Claims
    1. Sufficiency of the Evidence to Support Finding of Rape (Claims G.39, I.5, I.8–11)
    First, Rogers argues that there is insufficient evidence that he raped Beard, which was a
    component of his conviction for felony murder. He further contends that the Tennessee Supreme
    Court’s rejection of his sufficiency-of-the-evidence challenge was contrary to or an unreasonable
    application of clearly established federal law. We hold that this argument fails.
    When determining whether there is sufficient evidence to support a conviction, “the
    relevant question is whether, after viewing the evidence in the light most favorable to the
    prosecution, 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). “Under Jackson,
    federal courts must look to state law for ‘the substantive elements of the criminal offense,’ but
    the minimum amount of evidence that the Due Process Clause requires to prove the offense is
    No. 19-5427                                  Rogers v. Mays                                          Page 7
    purely a matter of federal law.” Coleman v. Johnson, 
    566 U.S. 650
    , 655 (2012) (per curiam)
    (quoting Jackson, 
    443 U.S. at
    324 n.16).
    Because AEDPA deference applies, “a federal court may not overturn a state court
    decision rejecting a sufficiency of the evidence challenge simply because the federal court
    disagrees with the state court” and “instead may do so only if the state court decision was
    ‘objectively unreasonable.’” Cavazos v. Smith, 
    565 U.S. 1
    , 2 (2011) (per curiam) (quoting
    Renico v. Lett, 
    559 U.S. 766
    , 773 (2010)).               “When reviewing whether the state court’s
    determination was ‘objectively unreasonable,’ this court necessarily engages in a two-step
    analysis.” Saxton v. Sheets, 
    547 F.3d 597
    , 602 (6th Cir. 2008). First, the court determines
    “whether the evidence itself was sufficient to convict under Jackson.” 
    Id.
     If not, the court “must
    then apply AEDPA deference and ask whether the state court was ‘objectively unreasonable’ in
    concluding that a rational trier of fact could have found [the defendant] guilty beyond a
    reasonable doubt.” 
    Id.
     “Thus, two layers of deference apply, one to the jury verdict, and one to
    the state appellate court.” Tanner v. Yukins, 
    867 F.3d 661
    , 672 (6th Cir. 2017).
    To establish felony murder in perpetration of a rape, the state needed to prove that Rogers
    killed Beard “in the perpetration of or attempt to perpetrate . . . rape.” 
    Tenn. Code Ann. § 39-13
    -
    202(a)(2) (1996). To establish rape, the state needed to prove that there was “unlawful sexual
    penetration.” 
    Id.
     § 39-13-522(a). To establish “sexual penetration,” the state needed to prove
    “sexual intercourse . . . or any other intrusion, however slight, of any part of a person’s body or
    of any object into the genital or anal openings of the victim’s . . . body.” Id. § 39-13-501(7).
    In rejecting Rogers’s sufficiency-of-the-evidence claim, the Tennessee Supreme Court
    relied on only four factors to support the conviction for rape: (1) the sperm heads found on the
    inside crotch of Beard’s shorts; (2) Beard’s mother’s testimony2 that Beard changed into clean
    shorts right before she disappeared; (3) the investigator’s testimony that Beard’s shirt was found
    inside out; and (4) the inference that Rogers was the last person to see Beard alive. Rogers II,
    2Meyer    testified that Beard “got her[self] some clean [shorts] and went in the bathroom and changed”
    around 1:45 p.m., R. 25-4 (Tr. at 96–97) (Page ID #3621–22), and Beard was missing by the time Meyer went
    outside at 1:55 p.m., id. at 97–98 (Page ID #3622–23).
    No. 19-5427                             Rogers v. Mays                                    Page 8
    
    188 S.W.3d at 617
    . The Tennessee Supreme Court concluded that it was reasonable to infer that
    the sperm heads came from Rogers and that they were evidence of penetration.
    This is a close case regarding sufficiency. The fact that Beard’s shirt was inside out was
    of limited relevance because (1) it does not provide evidence of penetration; and (2) Beard’s
    remains and clothing were scattered, which one of the state’s experts explained was due to
    scavenging by animals. R. 25-8 (Tr. at 88) (Page ID #4493). Thus, the only evidence of
    penetration was the sperm on Beard’s shorts, and the only evidence that Rogers was responsible
    for the sperm was the testimony that Beard had changed into clean shorts before she left the
    house, coupled with the evidence that Rogers abducted and killed her. Jurors may “draw
    reasonable inferences from basic facts to ultimate facts.” Jackson, 
    443 U.S. at 319
    . If, however,
    the evidence leads to only “reasonable speculation” about those ultimate facts, the evidence is
    insufficient to support a conviction. Newman v. Metrish, 
    543 F.3d 793
    , 796 (6th Cir. 2008). We
    agree with the trial court’s statement that the sufficiency of the evidence of penetration was
    “somewhat of a ‘close call.’” R. 24-5 (Order at 6) (Page ID #1173). On direct review, we might
    have found such evidence to be insufficient.
    Nevertheless, AEDPA deference applies. “The question ‘is not whether a federal court
    believes the state court’s determination . . . was incorrect but whether that determination was
    unreasonable—a substantially higher threshold.’” Knowles v. Mirzayance, 
    556 U.S. 111
    , 123
    (2009) (quoting Schriro v. Landrigan, 
    550 U.S. 465
    , 473 (2007)). In a case with a similarly
    small amount of direct evidence, we have nonetheless denied habeas relief, pointing to AEDPA’s
    deferential standard. See Durr v. Mitchell, 
    487 F.3d 423
    , 448 (6th Cir. 2007) (although the court
    might be “hard-pressed to conclude” on de novo review that there was sufficient evidence of
    rape in a case with “absolutely no physical evidence of any penetration,” AEDPA’s deferential
    standard led the court to affirm the denial of the habeas petition). We therefore affirm the denial
    of Rogers’s sufficiency claims.
    No. 19-5427                                    Rogers v. Mays                               Page 9
    2. Exclusion of Cross-Examination and Evidence Regarding Prior Sexual Acts
    Between the Victim and Her Brother (Claims G.21–24, G.26, G.44)
    Next, Rogers argues that the trial court improperly excluded cross-examination and
    evidence regarding prior sexual acts between Beard and her brother, Jeremy Beard.3 Through
    questioning of both Jeremy, R. 25-4 (Tr. at 44–46, 49) (Page ID #3569–71, 74), and Meyer, id. at
    209 (Page ID #3734), Rogers sought to admit evidence that Jeremy Beard had previously made
    statements that his biological father taught him to have sex with his sister. The trial court did not
    allow this line of questioning on the grounds that it was “remote in time and irrelevant and
    possibly confusing to the jury and inadmissible.” Id. at 70 (Page ID #3595); see id. at 214–15
    (Page ID #3739–40). Rogers argues that the exclusion of this evidence is an unreasonable
    application of Chambers v. Mississippi, 
    410 U.S. 284
     (1973). We disagree.
    In Chambers, the Supreme Court held that the trial court denied the defendant the right to
    a fair trial when it did not allow him to present certain exculpatory evidence. Another witness,
    McDonald, had given a sworn confession that he had committed the crime. Although Chambers
    was permitted to call McDonald and introduce the confession, Chambers was neither permitted
    to re-examine McDonald after McDonald recanted the confession nor allowed to call other
    witnesses to testify about McDonald’s verbal confessions to them. 
    Id.
     at 291–94. In concluding
    that “the exclusion of this critical evidence . . . denied him a trial in accord with traditional and
    fundamental standards of due process,” 
    id. at 302
    , the Court explained that the excluded
    evidence was “critical to Chambers’ defense,” “tended . . . to exculpate Chambers,” and “bore
    persuasive assurances of trustworthiness,” 
    id. at 297, 302
    .
    The Tennessee Supreme Court did not unreasonably apply Chambers. First, Jeremy’s
    past statements did not bear “persuasive assurances of trustworthiness.” 
    Id. at 302
    . Jeremy
    could not remember making the statements. R. 25-4 (Tr. at 44–46) (Page ID #3569–71); see
    Rogers II, 
    188 S.W.3d at 613
    . Jeremy struggled with significant psychological issues: he lived
    in a residential facility at the time of trial, and he had previously lived in various residential
    treatment facilities, mental-behavioral hospitals, group homes, detention centers, and foster
    homes. R. 25-4 (Tr. at 40–42) (Page ID #3565–67). Although his mother told a therapist that

    Jeremy told her that his father taught him to have sex with his sister, Meyer testified that she
    passed along this information “[t]o see if he really had or, you know, if he was telling the truth.”
    R. 25-4 (Tr. at 209) (Page ID #3734). No other evidence indicated that Jeremy had ever had sex
    with his sister, meaning that Jeremy’s statements were entirely uncorroborated. Rogers II, 
    188 S.W.3d at 613
    .
    Additionally, these statements were “not nearly as relevant to [the] defense as the
    confessions in Chambers.” Washington v. Renico, 
    455 F.3d 722
    , 735 (6th Cir. 2006). First, as
    the trial court explained, these statements—and any potential underlying sexual activity—were
    “remote in time.” R. 25-4 (Tr. at 70) (Page ID #3595). Jeremy had not lived with or seen his
    father since 1991, five years before his sister’s disappearance, R. 25-4 (Tr. at 211–12) (Page ID
    #3736–37). No evidence suggested that Jeremy had sex with his sister after that time. More
    significantly, unlike House v. Bell, 
    547 U.S. 518
    , 548 (2006), in which key physical evidence
    could be directly linked to a different suspect, nothing connected Jeremy to the semen on Jackie
    Beard’s shorts, especially in light of the testimony that Jackie Beard put on new shorts
    immediately before leaving the house.4 See Rogers II, 
    188 S.W.3d at 613
    . Accordingly, the
    Tennessee Supreme Court decision was not contrary to or an unreasonable application of
    Chambers.
    3. Ineffective Assistance of Trial Counsel by Not Adequately Challenging
    Semen Evidence (Claim C.12)
    Rogers argues that trial counsel rendered ineffective assistance by failing to investigate
    the serological evidence and conduct an adequate cross-examination regarding this evidence. To
    demonstrate ineffective assistance of counsel, Rogers must show “that counsel’s performance
    was deficient” and “that the deficient performance prejudiced the defense.”             Strickland v.
    Washington, 
    466 U.S. 668
    , 687 (1984). To show deficient performance, Rogers must show “that
    counsel made errors so serious that counsel was not functioning as the ‘counsel’ guaranteed the
    defendant by the Sixth Amendment.” 
    Id.
     To show prejudice, Rogers must show “that counsel’s
    errors were so serious as to deprive the defendant of a fair trial, a trial whose result is reliable.”
    4It   is undisputed that Jeremy had no involvement in the crime.

    Id.
     “Surmounting Strickland’s high bar is never an easy task.” Padilla v. Kentucky, 
    559 U.S. 356
    , 371 (2010).
    “The combined effect of Strickland and § 2254(d) is ‘doubly deferential’ review.” Foust,
    
    655 F.3d at 533
     (quoting Cullen v. Pinholster, 
    563 U.S. 170
    , 190 (2011)). “When § 2254(d)
    applies, the question is not whether counsel’s actions were reasonable” but “whether there is any
    reasonable argument that counsel satisfied Strickland’s deferential standard.” Harrington v.
    Richter, 
    562 U.S. 86
    , 105 (2011).
    For the reasons that follow, we hold that the Tennessee Court of Criminal Appeals
    unreasonably applied Strickland when it rejected Rogers’s ineffective-assistance claim regarding
    counsel’s failure adequately to challenge the semen evidence. Although this deficiency was not
    prejudicial at the guilt/innocence phase of trial, it was prejudicial at the penalty phase.
    a. Performance Prong
    Every court to consider this claim has found that Rogers’s counsel performed deficiently.
    See Rogers IV, 
    2019 WL 1331035
    , at *30; Rogers III, 
    2012 WL 3776675
    , at *47; R. 26-8 (Order
    at 59–60) (Page ID #7921–22). This issue is also undisputed before this court. See Appellee Br.
    at 39 n.3. The prosecution’s experts performed various scientific analyses to test for semen, and
    defense counsel failed adequately to challenge this evidence.
    In finding that counsel’s performance was deficient, the state post-conviction court
    explained:
    The testimony of Ms. Clement and Mr. Squibb at the [post-conviction]
    hearing reveals certain deficiencies in Mr. Warner’s cross-examination of those
    witnesses at trial. Mr. Squibb’s testing produced evidence favorable to the
    petitioner, but counsel did not present some of this evidence to the jury. For
    instance, the jury did not hear there were very few (or “rare,” the term used by the
    TBI lab to denote fewer than ten) sperm heads found on the microscopic slides
    developed from the victim’s shorts. Mr. Squibb was also not asked about his
    testing for semen in great detail; the jury heard no information about the
    mechanics of the acid phosphatase test (color changes, timing, etc.) or that Mr.
    Squibb’s acid phosphatase test yielded a “weak” positive result. The jury heard
    nothing about the P30 antigen as it related to seminal fluid or that Mr. Squibb’s
    testing yielded negative results for P30. The jury also did not hear that very little
    DNA was derived from the stains taken from the victim’s shorts. Perhaps most
    No. 19-5427                                  Rogers v. Mays                                        Page 12
    relevant, counsel for the petitioner did not present evidence attacking Mr.
    Squibb’s conclusion that the presence of sperm cells necessarily indicated the
    presence of semen. Given Ms. Clement’s testimony and the publication of the
    washing machine study5 in the Canadian forensic journal—an article published
    some four years before the trial in the instant case—such evidence was available
    to counsel.
    R. 26-8 (Order at 59–60) (Page ID #7921–22). The Tennessee Court of Criminal Appeals
    “agree[d] with the post-conviction court’s analysis.” Rogers III, 
    2012 WL 3776675
    , at *47. We
    also “give due deference to the conclusions of the trial judge on the effectiveness of counsel,
    because ‘[t]he judge, having observed the earlier trial, should have an advantageous perspective
    for determining the effectiveness of counsel’s conduct and whether any deficiencies were
    prejudicial.’” Foster v. Wolfenbarger, 
    687 F.3d 702
    , 708 (6th Cir. 2012) (quoting Massaro v.
    United States, 
    538 U.S. 500
    , 506 (2003)).
    For the reasons articulated by the post-conviction court, counsel’s performance was
    deficient. The Supreme Court has “long . . . recognized that ‘prevailing norms of practice as
    reflected in American Bar Association standards and the like . . . are guides to determining what
    is reasonable.” Padilla, 559 U.S. at 366 (quoting Strickland, 
    466 U.S. at 688
    ). The ABA
    standards that prevailed long before the trial speak clearly to the need for counsel to investigate
    and challenge the prosecution’s evidence, including the evidence offered by expert witnesses.
    The standards clarify that “[c]ounsel should conduct independent investigations.”                       ABA
    Guidelines for the Appointment and Performance of Counsel in Death Penalty Cases (1989)
    (hereinafter “ABA Std.”), 11.4.1(A).            Counsel “must be able to zealously challenge the
    prosecution’s evidence and experts through effective cross-examination.” 1989 ABA Std. 1.1
    (Commentary). “[C]ounsel should secure the assistance of experts where it is necessary or
    appropriate for . . . adequate understanding of the prosecution’s case.”                   1989 ABA Std.
    11.4.1(D)(7).
    5The   “washing machine study” refers to Clement’s post-conviction testimony about a 1996 article
    published in the Canadian Journal of Forensic Sciences that suggested spermatozoa could transfer in the washing
    machine from soiled to unsoiled underwear. R. 26-10 (Tr. at 250–52) (Page ID #832527).
    No. 19-5427                             Rogers v. Mays                                 Page 13
    Rogers’s counsel’s performance was not up to these standards. Although, as discussed
    above, the sperm evidence was the only evidence of penetration, Rogers’s counsel “wasn’t as
    concerned about” the semen evidence, R. 26-9 (Tr. at 83–84) (Page ID #8154–55), and did not
    ask Squibb “about his testing for semen in great detail.” Rogers III, 
    2012 WL 3776675
    , at *46
    (agreeing with post-conviction court). Counsel also failed to “present some of this [favorable]
    evidence to the jury,” including evidence that called into doubt whether the presence of sperm
    indicated the presence of semen. Id.; R. 26-9 (Tr. at 83) (Page ID #8154). Further, although a
    P30 test is used to indicate the presence of semen and although Squibb’s P30 test was negative,
    meaning that it did not indicate the presence of semen, Rogers’s counsel, at trial, established
    “nothing about the P30 antigen as it related to seminal fluid or that Mr. Squibb’s testing yielded
    negative results for P30.” R. 26-8 (Order at 59) (Page ID #7921). In fact, Rogers’s counsel later
    admitted that he did not even know what P30 is. R. 26-9 (Tr. at 89) (Page ID #8160). Because
    of these inadequacies, counsel’s performance was deficient.
    b. Prejudice Prong
    Rogers argues that the state court unreasonably applied Strickland by determining that
    there was no prejudice. To show prejudice, Rogers must 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 694
    . This probability must be “sufficient to undermine confidence in the
    outcome.” 
    Id.
     “It is not enough ‘to show that the errors had some conceivable effect on the
    outcome of the proceeding.’” Richter, 
    562 U.S. at 104
     (quoting Strickland, 
    466 U.S. at 693
    ).
    Because AEDPA deference also applies, Rogers must show that “[i]t would . . . have been
    unreasonable” for the state court to determine that “evidence of prejudice fell short of this
    standard.” Id. at 112.
    (1) Guilt/Innocence Phase
    The Tennessee Court of Criminal Appeals offered the following explanation to support
    its conclusion that there was no prejudice:
    [T]he fact remains that Squibb found sperm heads on the fabric samples taken
    from the crotch area of the victim’s shorts. Clement agreed at the post-conviction
    hearing with Squibb’s finding of sperm heads. The victim’s mother testified at
    No. 19-5427                                Rogers v. Mays                                   Page 14
    trial that the victim had put the shorts on right before leaving her house and
    disappearing. While Clement’s testimony at the post-conviction hearing
    established that it is possible for sperm heads to arrive on clothing while being
    laundered in a washing machine, she also testified that the experiments in which
    such transfer occurred involved washing new clothing with “a pair of underwear
    worn by someone who had consensual relations.” Thus, proof of these
    experiments would not have been relevant at trial unless the defense had also been
    able to establish at least some probability that the victim’s shorts had been washed
    with an item containing semen. No such probability was established at the post-
    conviction hearing. Therefore, we cannot conclude that Trial Counsel’s
    performance in his cross-examination of Squibb prejudiced the Petitioner.
    In sum, Trial Counsel should have attacked the State’s proof regarding the
    semen/sperm issue with more vigor. The Petitioner, however, has not established
    that the jury’s verdicts are unreliable as a result of this failure because there has
    been no showing that the defense would have been able to eliminate or
    completely discredit the State’s proof that sperm heads were found in the crotch
    area of the victim’s shorts. That proof, together with the substantial proof at trial
    that the Petitioner was the last person to see the victim alive, leaves us confident
    in the jury’s verdict. Accordingly, the Petitioner is not entitled to relief on this
    basis.
    Rogers III, 
    2012 WL 3776675
    , at *47. This analysis unreasonably applies Strickland.
    In determining prejudice, a court looks at “the totality of the evidence before the judge or
    jury.” Strickland, 
    466 U.S. at 695
    . “[A] verdict or conclusion only weakly supported by the
    record is more likely to have been affected by errors than one with overwhelming record
    support.” 
    Id. at 696
    ; see Foster, 687 F.3d at 710. As discussed above, penetration was a
    necessary element of the crime, and the only evidence of penetration was the sperm heads on the
    shorts.
    Counsel’s undisputed deficiencies directly relate to this evidence. As the Tennessee
    courts acknowledged, if counsel had not been deficient, the jury would have been able to hear
    that there were very few (fewer than ten) sperm heads on the slides developed from the shorts,
    that the acid phosphatase test yielded only a weak positive result, that the P30 antigen test was
    negative, that very little DNA could be taken from the sperm, that sperm does not necessarily
    indicate the presence of semen, and that sperm can be transferred between different items of
    clothing in the washing machine. Rogers III, 
    2012 WL 3776675
    , at *46. Together this evidence
    calls into question whether there was semen on the shorts—which, again, was the only evidence
    No. 19-5427                            Rogers v. Mays                                  Page 15
    of penetration presented by the prosecution. The Tennessee Court of Criminal Appeals thus
    unreasonably applied Strickland when it found that this deficiency did not prejudice the
    defendant.
    The Tennessee Court of Criminal Appeals’ unreasonable application of Strickland was
    rooted in its reasoning that there was no prejudice because the defense could not have
    “eliminate[d] or completely discredit[ed] the State’s proof that sperm heads were found in the
    crotch area of the victim’s shorts.” 
    Id. at *47
    . Rogers did not need to “eliminate or completely
    discredit” this evidence to undermine confidence in the jury verdict. This is not a case in which
    there was substantial other evidence pointing to rape. Compare Higgins v. Renico, 
    470 F.3d 624
    ,
    634 (6th Cir. 2006) (failure to cross-examine key witness was prejudicial because without this
    testimony, the state’s case was “far from overwhelming”), with Poindexter v. Mitchell, 
    454 F.3d 564
    , 572 (6th Cir. 2006) (failing to cross-examine witness about inconsistencies in testimony
    was not prejudicial because multiple eyewitnesses saw the defendant commit the crime).
    Because penetration—a necessary element of the rape conviction—was “only weakly supported
    by the record,” it was “more likely to have been affected by errors than [a conclusion] with
    overwhelming record support.” Strickland, 
    466 U.S. at 696
    . In short, where (1) the trial court
    acknowledged that whether there was sufficient evidence to support a rape conviction was a
    “close call,” R. 24-5 (Order at 6) (Page #1173); (2) counsel’s performance was undisputedly
    deficient by failing to undermine the only evidence of penetration; and (3) penetration is a
    necessary element of the rape conviction, it follows that (4) the state court unreasonably applied
    Strickland when it determined that counsel’s deficient performance did not render the rape
    conviction unreliable.
    Nevertheless, we cannot say that there was prejudice at the guilt/innocence phase of trial.
    The jury convicted Rogers of both felony murder and premeditated murder, R. 25-11 (Tr. at 221–
    22) (Page ID #5132–33), and the judge merged the two felony murder counts—one for felony
    murder in perpetration of kidnapping and one for felony murder in perpetration of rape—into the
    count for premeditated murder, R. 24-5 (J.) (Page ID #1142). Rogers now argues that the error
    regarding the rape conviction goes to both his conviction for felony murder in perpetration of
    rape and his conviction for premeditated murder. We agree that the errors undermine our
    No. 19-5427                                   Rogers v. Mays                                           Page 16
    confidence in the conviction for felony murder in perpetration of rape. It is not necessary for us
    to decide whether these errors prejudicially impacted the premeditated murder conviction
    because the jury also convicted Rogers of first-degree felony murder in perpetration of a
    kidnapping.      R. 25-11 (Tr. at 222–23) (Page ID #5132–33).                     Because all three murder
    convictions were merged, this error could not undermine Rogers’s conviction for murder.
    (2) Penalty Phase
    Although Rogers’s ineffective-assistance claim does not undermine our confidence that,
    absent these errors, the jury would have convicted Rogers of murder, these errors were
    prejudicial at the penalty phase. Because the state court did not address this question, see Rogers
    III, 
    2012 WL 3776675
    , at *47, we review de novo the impact of the rape conviction on the jury’s
    weighing of the aggravating and mitigating factors. See Williams v. Anderson, 
    460 F.3d at 796
    .
    The rape of a nine-year-old child is so grievous that we conclude that, in the absence of a rape
    conviction, there is a reasonable probability that at least one juror would have weighed the
    aggravating and mitigating factors differently.
    In Tennessee, two relevant statutory requirements govern the imposition of the death
    penalty. First, “[n]o death penalty . . . shall be imposed but upon a unanimous finding that the
    state has proven beyond a reasonable doubt the existence of one (1) or more of the statutory
    aggravating circumstances.” 
    Tenn. Code Ann. § 39-13-204
    (i) (1996).6 Second, the Tennessee
    Code authorizes the death penalty only if the aggravating factors “have been proven by the state
    beyond a reasonable doubt” and “have been proven by the state to outweigh any mitigating
    circumstances beyond a reasonable doubt.”                     
    Id.
     § 39-13-204(g)(1)(A)–(B).             If, after
    deliberations, “the jury still cannot agree as to sentence, the trial judge shall dismiss the jury and
    the judge shall impose a sentence of imprisonment for life.” Id. § 39-13-204(h)(1). In short, if
    there is a reasonable probability that the rape-related aspect of the crime impacted the way that at
    least one juror weighed the aggravating and mitigating factors, the error was prejudicial. The
    state’s brief addressed only § 39-12-204(i) and did not address—at all—the question raised by
    § 39-13-204(g)(1) of whether the rape conviction would cause the jury to weigh the aggravating
    6Our   analysis does not rest on § 39-12-204(i). At least two aggravating factors would exist even in the
    absence of the rape conviction, so, the requirements of § 39-13-204(i) are met regardless of trial counsel’s error.
    No. 19-5427                             Rogers v. Mays                                   Page 17
    and mitigating factors differently. See Appellee Br. at 28–29 (discussing, in the context of the
    sufficiency argument, the statutory aggravating factors).
    Our analysis turns on the statutory requirement about which the state was silent: the
    requirement in § 39-13-204(g)(1)(B) that the aggravating factors outweigh the mitigating
    circumstances “beyond a reasonable doubt.” The rape of a child is a particularly significant
    aggravating factor—much more so than many of the other aggravators. As a society, we view
    child rape as particularly heinous—perhaps even the most heinous thing that a person can do.
    This matters at the penalty phase, when jurors must weigh the aggravating factors against the
    mitigating ones. An aggravating factor that is accorded significant weight will thus have a
    significant impact on this weighing calculus.
    The Supreme Court has made clear that a child-rape conviction completely distorts the
    weighing of aggravating and mitigating factors in a way that cannot readily be rectified. See
    Kennedy v. Louisiana, 
    554 U.S. 407
    , 439 (2008). Child rape is “a crime that in many cases will
    overwhelm a decent person’s judgment” in a way that makes it difficult for a jury to balance the
    other aggravating and mitigating factors. 
    Id.
     The dissent correctly points out that the criminal
    conduct in this case was “highly inflammatory and disturbing” even without the rape conviction.
    Dissenting Op. at 46. We do not disagree. But the combination of rape and murder of a nine-
    year-old child is so disturbing that it is significantly likely that the child rape conviction would
    have “overwhelm[ed]” at least one juror’s judgment in a way that affected their weighing of the
    aggravating and mitigating circumstances. Kennedy, 
    554 U.S. at 440
    . Although there were
    multiple aggravating factors in this case, the rape of a child is by far the most significant one.
    Both crimes are heinous. But raping and murdering a child is far worse than murder alone: the
    added element of child rape makes the crime altogether more sadistic.
    The uniquely aggravating nature of child rape is heightened by the fact that at the time of
    Rogers’s trial, the Supreme Court had not yet prohibited the imposition of the death penalty for
    cases of child rape that did not result in the death of the victim. See Kennedy, 
    554 U.S. 407
    .
    No. 19-5427                                   Rogers v. Mays                                          Page 18
    Indeed, the rape of a child was the last non-homicide crime against a person for which the death
    penalty was authorized. See id.7
    Because we look at whether there is a reasonable probability that one juror would have
    changed their mind, we note that at least some Tennesseans believed that child rape alone should
    be grounds for the death penalty, even in the absence of a homicide offense. True, Tennessee did
    not, at that time, have a death penalty for child rape. Tennessee previously had such a law, but it
    was invalidated by the Tennessee Supreme Court because it imposed a mandatory death penalty
    for child rape. See Collins v. State, 
    550 S.W2d 643
    , 646 (Tenn. 1977) (invalidating Tennessee’s
    mandatory death penalty); 
    Tenn. Code Ann. §§ 39-3702
    , 39-3705 (1974) (imposing mandatory
    death penalty for cases of child rape). Within a few years of the trial, Tennessee legislators
    proposed a capital child-rape bill and withdrew it only because of budgetary concerns. Kennedy,
    
    554 U.S. at 459
    . Because, in this case, the child rape conviction need only have impacted the
    way that one juror weighed the aggravating and mitigating factors, we do not need to speculate
    about the potential trajectory of the bill to understand its significance. Instead, the efforts—
    spanning decades—of democratically elected Tennessee legislators to impose the death penalty
    for perpetrators of child rape confirm that at least some Tennesseans believed that child rape
    provided independent grounds to impose the death penalty. Such views reinforce our conclusion
    that there is a reasonable probability that at least one juror would have weighed the aggravating
    and mitigating factors differently absent the child rape conviction.
    The prosecution’s strategy at the penalty phase confirms our conclusion. In closing
    argument, the prosecution repeatedly centered on the rape conviction.                        The prosecution
    emphasized that Rogers killed Beard:
    because he intended to rape this child, which he did. Because he raped the child,
    he had to remove her from this county, and take her some place where he would
    hope that she would never, ever be found . . . . And the reason for that, ladies and
    gentlemen, because of this aggravator, which is so powerful in and of itself that
    will convince you—convict this man and sentence him to death, because he did
    not want to see her come through that door back here, walk up that aisle right
    here, wearing her Minnie Mouse shirt and those teal shorts and those little sandals
    7Child  rape was a permissible capital offense for more than thirty years after the Supreme Court held the
    death penalty could not be imposed in cases of rape of adults. See Coker v. Georgia, 
    433 U.S. 584
     (1977).
    No. 19-5427                             Rogers v. Mays                                      Page 19
    that she had on, walk up here, take the oath and get in that chair and point the
    finger of guilt to this man. That’s why, that’s why he killed her. And ladies and
    gentlemen, that is enough in of itself to sentence him to death.
    R. 25-17 (Tr. at 7–8) (Page ID #5952–53). The prosecutor’s repeated emphasis on the rape of a
    child and Rogers’s efforts to conceal that rape, and the prosecutor’s statements that this alone
    warrants the death sentence, show that, in this case, the rape conviction was prejudicial.
    When reweighing the aggravating and mitigating factors, we must also consider the
    weight of the mitigating factors. At the penalty phase of trial, several witnesses, including
    Rogers’s sibling Sam, told the jury about the horrific physical abuse that Rogers experienced as a
    child: to provide just a few examples, his stepfather frequently and violently beat him, regularly
    chained him to the bed, and rubbed Rogers’s face in his own excrement as punishment. See
    Section I, supra. Two experts testified that Rogers’s psychological disorders stemmed from the
    abuse and trauma he endured. See id. There are weighty factors on both the aggravating and the
    mitigating sides of the scale.
    To the extent that the dissent implies that the facts may have led the jury to suspect rape,
    even if they lacked “conclusive evidence of rape,” this implication does not affect our analysis.
    See Dissenting Op. at 46.        The Tennessee Statute directs jurors to weigh only statutory
    aggravating circumstances against all mitigating factors. See 
    Tenn. Code Ann. § 34-12-204
    (g).
    And these aggravating circumstances must be proven “beyond a reasonable doubt.” 
    Id.
     The
    dissent highlights other concerning facts, but those facts do not impact the weighing calculation
    because (1) they are not statutory factors, see 
    id.
     § 39-12-204(i); and (2) absent counsel’s
    undisputedly deficient performance, they would not have been proven beyond a reasonable
    doubt, see id. § 39-12-204(g)(1).
    As explained above, even under AEDPA’s deferential standard, we cannot be confident
    that, in the absence of counsel’s errors, Rogers would have been convicted of rape. We thus
    consider de novo the impact of removing this rape conviction.            Eliminating the statutory
    aggravator for rape would have removed the most powerful aggravating factor and would have
    likely caused the jury to weigh the aggravating and mitigating factors differently. Murdering a
    child is an unspeakably tragic crime. But raping and then murdering a child is altogether more
    No. 19-5427                                 Rogers v. Mays                                 Page 20
    heinous. Thus, on de novo review, we conclude that there is a reasonable probability that, to at
    least one juror, this difference mattered.
    We therefore reverse the district court’s decision with respect to this claim and remand to
    the district court with instructions to grant Rogers’s habeas petition on this claim with respect to
    the penalty phase.
    C. Procedurally Defaulted Claims
    Rogers also argues that the Martinez-Trevino exception to procedural default applies to
    an additional four groups of ineffective-assistance-of-counsel claims. Federal habeas courts are
    barred from considering federal constitutional claims that were defaulted in state court unless the
    prisoner can demonstrate cause for the default and actual prejudice that resulted or a fundamental
    miscarriage of justice. Coleman v. Thompson, 
    501 U.S. 722
    , 750 (1991). Although ineffective
    assistance of counsel on direct appeal may constitute cause to excuse the default, ineffective
    assistance of post-conviction counsel typically “cannot constitute cause to excuse the default in
    federal habeas.” 
    Id. at 757
    .
    In Martinez v. Ryan, 
    566 U.S. 1
    , 9 (2012), the Court established a “narrow exception” to
    this rule: “[i]nadequate assistance of counsel at initial-review collateral proceedings may
    establish cause for a prisoner’s procedural default of a claim of ineffective assistance at trial.”
    In Trevino v. Thaler, the Court clarified that procedural default could be excused if:
    (1) the claim of “ineffective assistance of trial counsel” was a “substantial” claim;
    (2) the “cause” consisted of there being “no counsel” or only “ineffective”
    counsel during the state collateral review proceeding; (3) the state collateral
    review proceeding was the “initial” review proceeding in respect to the
    “ineffective-assistance-of-trial-counsel claim”; and (4) state law requires that an
    “ineffective assistance of trial counsel [claim] . . . be raised in an initial-review
    collateral proceeding.”
    
    569 U.S. 413
    , 423 (2013) (quoting Martinez, 
    566 U.S. at
    14–15, 17–18). Trevino extended
    Martinez to states in which the “state procedural framework, by reason of its design and
    operation, makes it highly unlikely in a typical case that a defendant will have a meaningful
    opportunity to raise a claim of ineffective assistance of trial counsel on direct appeal.” Id. at 429.
    The Martinez-Trevino rule applies in Tennessee, and accordingly prongs three and four of the
    No. 19-5427                                    Rogers v. Mays                                            Page 21
    test are met. Sutton v. Carpenter, 
    745 F.3d 787
    , 795–96 (6th Cir. 2014). As a result, the
    exception applies to Rogers’s claims if the underlying ineffective-assistance-of-trial-counsel
    claim is substantial and if ineffective counsel during the initial collateral-review proceeding
    prevented Rogers from raising the claim. To be substantial, a claim must have “some merit.”
    Martinez, 566 U.S. at 14.
    In this case, habeas counsel performed a thorough investigation, uncovering extensive
    and compelling evidence that trial counsel failed to pursue. This evidence was presented to the
    district court. Typically, we would decide the case based on the evidence that was before the
    district court. However, after the parties in this case had completed briefing and oral argument,
    the United States Supreme Court decided Shinn v. Ramirez, 
    142 S. Ct. 1718
     (2022). This
    decision held that “a federal habeas court may not conduct an evidentiary hearing or otherwise
    consider evidence beyond the state-court record based on ineffective assistance of state
    postconviction counsel.” 
    Id. at 1734
    . As a result of this timeline, we do not have the benefit of
    the parties’ briefing about how Shinn v. Ramirez should affect the disposition of this case.
    Although we might typically remand for consideration in light of the Supreme Court’s decision
    in Shinn v. Ramirez, our grant of habeas corpus at the penalty phase on Claim C.12 (ineffective
    assistance for failing adequately to challenge the semen evidence) entitles Rogers to resentencing
    in state court. Resentencing vitiates the need for the district court to consider these issues, and
    therefore we simply vacate the district court’s opinion as to these claims.
    1. Failure to Investigate Jeremy Beard as a Source of Semen (Claims C.8, D.26)
    Rogers argues that the Martinez-Trevino exception applies to his claim that trial counsel
    was ineffective by failing to investigate Jeremy Beard as a source of the sperm found on Jackie
    Beard’s shorts. Rogers did not raise these claims in any state court proceeding and presented
    them for the first time before the federal district court on habeas review.8
    8These claims are similar to Claim C.12 (that trial counsel failed to investigate the semen evidence), which
    Rogers exhausted in state court and we address in section II.B.3. The district court acknowledged the potential
    overlap between these two claims. See Rogers IV, 
    2019 WL 1331035
    , at *106 (analyzing these claims “[t]o the
    extent that these are indeed new claims (as opposed to new evidence in support of an exhausted claim that counsel
    was ineffective in failing to prove that Jeremy was the source of the semen)”). On appeal, neither party argues that
    these claims are merely an extension of Claim C.12. Despite the similarities between these claims, they are properly
    No. 19-5427                                   Rogers v. Mays                                           Page 22
    Although we cannot say what evidence may ultimately be considered, we disagree with
    the district court that, based on the record before it, Rogers’s ineffective-assistance claim was
    insubstantial. The district court found that no new evidence conflicted with the evidence that
    Beard left the house in clean shorts, and the district court doubted that trial counsel could have
    obtained this evidence if they had tried. Rogers IV, 
    2019 WL 1331035
    , at *106-07. The
    evidence before the district court was inconsistent with these findings. For example, new
    evidence suggested that Jackie did not leave the house in clean shorts: this included significant
    evidence that there were regularly piles of dirty laundry throughout the house, R. 129 (Jeremy
    Beard Dep. at 26) (Page ID #26240); R. 125-13 (Edgin Decl. ¶ 7) (Page ID #24377), and that the
    children frequently wore dirty and unwashed clothes that smelled of animal urine, R. 125-9
    (Evans Decl. ¶¶ 3–5) (Page ID #24365); R. 125-10 (Medlock Decl. ¶ 5) (Page ID #24367); 125-
    11 (Donaldson Smith Decl. ¶ 2) (Page ID #24369); R. 125-12 (Thompson Decl. ¶¶ 6–7) (Page ID
    #24372–73); R. 125-13 (Edgin Decl. ¶¶ 5, 7) (Page ID #24376–77); R. 129 (Jeremy Beard Dep.
    at 68–69) (Page ID #26282–83), as well as Jeremy Beard’s statement that he used a pair of
    Jackie Beard’s shorts to wipe himself off after he masturbated “within a couple of days of her
    disappearance,” R. 81-2 (Jeremy Beard Decl. at 2) (Page ID #12103).9 This evidence could not
    have been dismissed as unattainable because (1) there were multiple paths to eliciting this
    evidence, including by talking to teachers, caregivers, and friends; and (2) witnesses’ potential
    reluctance to share information cannot excuse failing to investigate that witness in the first place.
    See 1989 ABA Std. 11.4.1 (commentary) (“Nor may counsel ‘sit idly by, thinking that
    investigation would be futile.’”).
    A proper inquiry into whether these claims are substantial instead would have asked
    whether there is “some merit” to the claim that counsel’s deficient investigation prejudiced
    Rogers. Martinez, 566 U.S. at 14. The record before the district court showed that the claim had
    at least some merit.
    viewed separately because the issues exhausted in state court (encompassed in Claim C.12) related only to the
    scientific investigation and cross-examination. In contrast, Claims C.8 and D.26 address the investigation into the
    specific facts involving Jeremy Beard’s actions and home conditions that could have shown that Jeremy was a
    source of the semen.
    9Jeremy  had a history of using others’ underwear while masturbating. R. 125-6 (Westerbeck-Deckle Decl.
    ¶ 13) (Page ID #24342).
    No. 19-5427                                Rogers v. Mays                               Page 23
    First, Rogers presented to the district court a substantial claim that counsel’s performance
    was deficient.    Because the performance prong “is necessarily linked to the practice and
    expectations of the legal community[,] ‘[t]he proper measure of attorney performance remains
    simply reasonableness under prevailing professional norms.’” Padilla, 559 U.S. at 366 (quoting
    Strickland, 
    466 U.S. at 688
    ). In this case, the prevailing professional norms required a more
    thorough investigation.    “[C]ounsel has a duty to make reasonable investigations,” and “a
    particular decision not to investigate must be directly assessed for reasonableness in all the
    circumstances, applying a heavy measure of deference to counsel’s judgments.” Strickland,
    
    466 U.S. at 691
    . The operative ABA standards at the time provided that “[c]ounsel should
    conduct independent investigations relating to the guilt/innocence phase and to the penalty phase
    of a capital trial.”    1989 ABA Std. 11.4.1(A); see 1989 ABA Std. 1.1 (Commentary)
    (“Substantial pretrial investigation is a necessary base for intelligent assessment of possibly
    conflicting options as to the defense.”).
    As discussed above, the only pieces of evidence presented at trial supported the claim that
    Rogers raped Beard: the sperm on Beard’s shorts and Meyer’s testimony that Beard changed
    into clean shorts shortly before she was abducted. Despite counsel’s theory that Jeremy Beard
    may have been the source of the sperm, counsel did not talk to Jeremy before the trial at all, nor
    did they ask any other potential witness, such as Jeannie Meyer, whether Jeremy could have been
    the source of the semen. Nor did they interview any possible witnesses to determine whether
    Jackie Beard’s shorts were clean. Nor did they ask Jeremy Beard at trial whether he might have
    been the source of the semen. These failures “resulted from [counsel’s] ignorance of this
    evidence, not from an informed choice” about trial strategy. Sowell v. Anderson, 
    663 F.3d 783
    ,
    790 (6th Cir. 2011).
    Rogers also presented the district court with a substantial claim that counsel’s deficient
    performance prejudiced him. As discussed above, a deficiency that failed to uncover evidence
    that called into question the sperm on the shorts prejudiced Rogers at the penalty phase of trial,
    but not at the guilt/innocence phase of trial. As a result, Rogers’s ineffective-assistance claim
    regarding counsel’s failure to investigate Jeremy Beard as a source of the semen is substantial.
    Thus, we vacate this portion of the district court’s opinion.
    No. 19-5427                             Rogers v. Mays                                  Page 24
    Although we find this evidence compelling, we do not yet know how much of it may
    ultimately be considered in light of Shinn, and we do not make any conclusions of our own with
    regard to these ineffective-assistance claims. Because Rogers is entitled to resentencing based
    on Claim C.12, however, there is no need for the district court, on remand, to decide what
    evidence it can consider.
    2. Mitigation Claims (Claims C.20–23, E.2–5)
    We next turn to Rogers’s claims that counsel was ineffective in their investigation,
    development, and presentation of mitigating evidence. We hold that these claims were defaulted
    at the initial post-conviction proceeding and not on appeal. Therefore, the Martinez-Trevino
    exception may excuse Rogers’s procedural default of these claims.
    a. Procedural Default
    Rogers argues that Martinez-Trevino excuses the procedural default of his ineffective-
    assistance claims with respect to counsel’s failure to investigate, develop, and present mitigating
    evidence. It is undisputed that these claims were procedurally defaulted in state court post-
    conviction proceedings. What is disputed, however, is the stage at which these claims were
    defaulted. The state argues that the mitigation claims were presented and considered at the trial-
    court level in the post-conviction stage but were defaulted on appeal. Appellee Br. at 50. Rogers
    argues that these cases were procedurally defaulted at the initial post-conviction proceeding
    because his mitigation claims were so barebones that they were never fairly presented to the state
    post-conviction trial court.
    Although the Martinez-Trevino exception can excuse procedural default at the initial
    post-conviction stage, it “does not apply to save procedural defaults that occur in ‘appeals from
    initial-review collateral proceedings.’” Middlebrooks v. Carpenter, 
    843 F.3d 1127
    , 1136 (6th
    Cir. 2016) (quoting Martinez, 
    566 U.S. at 16
    ). This court reviews de novo whether a habeas
    claim is barred by procedural default. Id. at 1134.
    No. 19-5427                              Rogers v. Mays                                     Page 25
    “To avoid procedural default, the petitioner must exhaust all state-court remedies,” which
    requires “fair presentation of the federal claim to the state courts.”        Williams v. Mitchell,
    
    792 F.3d 606
    , 613 (6th Cir. 2015) (internal citations and quotation marks omitted). “To fairly
    present a federal claim, a state prisoner is required to present the state courts with ‘both the legal
    and factual basis’ for the claim.” 
    Id.
     (quoting Williams v. Anderson, 
    460 F.3d at 806
    ). However,
    “post-conviction counsel’s failure to take all possible steps to fully develop a claim cannot be the
    ‘cause’ of a default as long as counsel properly raised the claim and made a good-faith effort in
    presenting it.” Hugueley v. Mays, 
    964 F.3d 489
    , 499 (6th Cir. 2020).
    In Rogers’s state post-conviction petition, he stated only that “[c]ounsel failed to
    adequately investigate defense expert mitigation evidence” and “[c]ounsel failed to present
    available mitigation testimony and evidence during the sentencing phase of the trial.” R. 26-7
    (Second Am. Pet. ¶¶ 4.11, 5.24) (Page ID #7762, 7767). The petition did not offer factual
    allegations to support either claim. 
    Id.
     Additionally, as the state post-conviction court noted,
    “no proposed mitigation evidence was presented during the evidentiary hearing.” R. 26-8 (Order
    at 160–61) (Page ID #8022–23). As a result, the post-conviction court found that it could “only
    speculate as to the nature of any proposed mitigation evidence or the manner in which it would
    have aided the petitioner.” 
    Id. at 160
     (Page ID #8022). Because post-conviction counsel entirely
    failed to develop this claim, there was no claim for the post-conviction court to analyze.
    We have repeatedly held that a claim is procedurally defaulted when counsel entirely
    failed to develop a claim in a way that would allow a court to adjudicate an issue. In Mitchell v.
    Genovese, we held that a petitioner had procedurally defaulted his claim when the court’s
    holding “was specifically predicated on a lack of evidence regarding the facts that pertain to [the]
    claim.” 
    974 F.3d 638
    , 648 (6th Cir. 2020) (internal citations omitted). In Williams v. Mitchell,
    we held that a habeas petitioner failed to exhaust his claim before the Ohio Supreme Court when
    he made a “general reference to his trial counsel’s failure to ‘pursue’ his intellectual limitations
    at trial” but did not “set[] forth the factual and legal underpinnings for the claim.” 792 F.3d at
    614. As a result, the state court was “unable to assess the facts and the law bearing on his
    constitutional claim.” Id. at 615. In Williams, we applied this analysis to hold that the claims
    were defaulted on appeal. Rogers’s claims were defaulted for the same reason but at the initial
    No. 19-5427                                    Rogers v. Mays                                            Page 26
    post-conviction proceeding. The Martinez-Trevino exception is thus applicable to these claims.
    A contrary holding would “deprive [Rogers] of any review of that claim at all.” Trevino,
    569 U.S. at 423.10 We thus vacate the district court’s opinion as to these claims.
    b. Substantiality of Mitigation Claims
    Because Rogers’s mitigation claims were not fairly presented—and thus were
    defaulted—at the initial post-conviction proceeding, the Martinez-Trevino exception to
    procedural default applies if the claim is “substantial” and post-conviction counsel’s
    ineffectiveness caused the procedural default. Martinez, 566 U.S. at 14. For a claim such as
    this, which asserts that counsel was ineffective with regard to the investigation into and
    development of mitigation evidence, we would typically decide whether counsel’s performance
    was deficient and whether the available mitigation evidence shows that Rogers was prejudiced as
    a result. However, we do not have the benefit of the parties’ briefing on the impact of Shinn v.
    Ramirez and what evidence we may consider. And, in light of our grant of habeas corpus at the
    penalty phase on Claim C.12, Rogers is entitled to resentencing regardless of the outcome on
    these mitigation claims. Thus, at this stage, we do not offer any conclusions regarding the
    substantiality of Rogers’s mitigation claims.
    We note, however, that the evidence before the district court starkly illustrates counsel’s
    derelict investigation into and presentation of what should have been a highly compelling and
    disturbing account. Although we do not determine the extent to which a federal habeas court can
    consider any of this evidence, we cannot envision a just or humane system that, in the face of
    such overwhelming evidence, would provide no relief.
    10This    case is distinguishable from West v. Carpenter, 
    790 F.3d 693
     (6th Cir. 2015), in which the
    petitioner’s presentation of the claim was poor but the post-conviction court still had enough information to analyze
    the claim. In West, the petitioner did not “expressly” raise a conflict-of-interest claim but provided the grounds
    upon which that claim rested: that his lawyers would not present evidence of his parents’ abuse because his parents
    were the ones paying the attorney. 
    Id.
     at 695–96. In that case, the post-conviction court was able to evaluate the
    merits of the claim. 
    Id. at 699
    . By contrast, the judge in this case could only “speculate” about the nature of the
    claim. R. 26-8 (Order at 160) (Page ID #8022).
    No. 19-5427                             Rogers v. Mays                                   Page 27
    (1) Performance Prong
    If we were to consider the evidence that was presented to the district court, we would
    have no reservations in declaring counsel’s performance to be deficient. “To establish deficient
    performance, a petitioner must demonstrate that counsel’s representation ‘fell below an objective
    standard of reasonableness.’” Wiggins v. Smith, 
    539 U.S. 510
    , 521 (2003) (quoting Strickland,
    
    466 U.S. at 688
    ). “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.” Id. at 527.
    Although we will defer to counsel’s strategic decisions, the record before the district
    court showed that the decision not to investigate was not strategic. “‘[S]trategic choices made
    after less than complete investigation are reasonable’ only to the extent that ‘reasonable
    professional judgments support the limitations on investigation.” Wiggins, 
    539 U.S. at 533
    (quoting Strickland, 
    466 U.S. at
    690–91). In this case, “counsel never offered, and no evidence
    supports, any tactical rationale for the pervasive oversights and lapses here.” Andrus v. Texas,
    
    140 S. Ct. 1875
    , 1883 (2020). Counsel’s deficient performance could not be dismissed as
    strategy gone awry.
    A checklist made by counsel near the trial date highlights their failure to obtain necessary
    tests and consults. See R. 124-9 (Notes) (Page ID #24211–14). The first eight items on the list
    are checked off: with respect to those items, counsel did what they needed to do. 
    Id. at 1
     (Page
    ID #24211). No checkmarks, however, appear next to the ninth and tenth items: “Obtain
    Neurologist” and “Obtain Neuropsych.” 
    Id. at 2
     (Page ID #24212). Underneath these headers,
    counsel noted that they “need[ed] standard neuro exam; MRI; PET scan.” 
    Id.
     Yet, counsel
    never did these things despite an attempted “last minute scramble” to do so. R. 123-1 (Gleason
    Decl. at 5) (Page ID #23923). Extensive other evidence confirms that trial counsel knew Rogers
    needed a full neurological evaluation but failed to obtain one. See, e.g., R. 124-4 (Resource
    Counsel Notes) (Page ID #24199) (“[G]iven the [history] of injuries, [an] MRI could be
    helpful.”); R. 124-5 (Mem. at 2) (Page ID #24203) (investigator again suggested that counsel
    seek a neurological evaluation). Subsequent notes from counsel show that they looked into
    getting a neurological examination. R. 124-6 (Notes) (Page ID #24205) (counsel thought about
    No. 19-5427                            Rogers v. Mays                                  Page 28
    obtaining a neurological evaluation); R 124-7 (Notes) (Page ID #24207) (same). This failure to
    obtain neurological examinations was particularly deficient considering that at least one of
    Rogers’s attorneys believed that Rogers’s history made the need to consult with a
    neuropsychologist and to obtain brain imaging “obvious.” 
    Id. at 4
     (Page ID #23922).
    Counsel was correct that the need for brain imaging was obvious. Among other records,
    trial counsel uncovered a 1982 psychological report from the Baton Rouge Health Center that
    recommended “a neurological work-up” because Rogers’s “history of head traumas . . . may be
    associated with organic impairment.” R. 115-25 (Letter) (Page ID #14302). He never received
    any such workup. The defense also uncovered medical records showing that Rogers suffered
    repeated head injuries in his adulthood. In June of 1980, he was hospitalized after being beaten
    until he was unconscious. R. 113-10 (Clinical Records) (Page ID #13763, 13772). In February
    of 1982, he was in an automobile accident, went through a windshield, was hospitalized for
    thirteen days after he suffered injuries—including head injuries—and “lost a year of memory.”
    R. 115-23 (Discharge Summary) (Page ID #14239); R. 115-24 (Mental Illness Application)
    (Page ID #14300). He was hospitalized again and sent to the hospital’s trauma bay in 1988 after
    he was struck by a truck and a car while walking and sustained significant injuries, including a
    scalp laceration. R. 117-8 (Medical Records) (Page ID #14663–65).
    Counsel also learned of head injuries that Rogers suffered as a child. They learned that,
    as a child, Rogers fell from an upper bunk onto a concrete floor, which significantly changed his
    personality.   R. 123-19 (Einstein Mem. at 2) (Page ID #24160).           Further, at least eight
    individuals told the investigator that Rogers endured extensive physical abuse and violence
    throughout his childhood and adolescence. See R. 123-18 (Einstein Mem. at 1–2) (Page ID
    #24156–57); R. 123-19 (Einstein Mem. at 1–4) (Page ID #24159–62). Reports of this abuse
    would have given a competent attorney additional reasons to suspect that Rogers had suffered
    brain injuries. Counsel should have investigated further. They did not.
    No. 19-5427                                   Rogers v. Mays                                          Page 29
    All told, counsel had evidence that Rogers suffered at least four significant head injuries
    and may have suffered more. Counsel’s own notes show they knew that they needed to obtain
    neurological evaluations and brain scans. And yet, they did not.11 Instead, “counsel chose to
    abandon their investigation at an unreasonable juncture, making a fully informed decision with
    respect to sentencing strategy impossible.” Wiggins, 
    539 U.S. at
    527–28.
    Trial counsel’s conduct fell well below the prevailing norms at the time. Although ABA
    Guidelines are not “inexorable commands,” they are “valuable measures of the prevailing
    professional norms of effective representation. Padilla, 
    559 U.S. at 367
    . The relevant ABA
    Guidelines provided that, in preparation for the sentencing phase, counsel should consider
    “[e]xpert witnesses to provide medical, psychological, sociological, or other explanations for the
    offense(s).” 1989 ABA Std. 11.8.3(F)(2). The 1992 Tennessee Association of Criminal Defense
    Lawyers Manual offered more detailed guidance, noting the importance of obtaining a
    “[p]sychological [d]iagnosis and [e]xpert [a]ssistance.” R. 119-14 (Manual at 5.18) (Page ID
    #16403). It further explained:
    The first and most important [psychological explanation] is organic mental
    disorder, i.e., brain damage. If your client has had illnesses, accidents, or head
    injuries, . . . you must consider brain damage as a probable cause for his violent
    behavior. This means that the client must be evaluated by a neuropsychologist or
    neurologist . . . .
    Id. at 5.18–5.19 (Page ID #16403–04). Because counsel should have pursued a neurological
    evaluation and brain scans, evaluating the evidence before the district court would necessarily
    lead to the conclusion that counsel’s investigation into evidence of brain damage was deficient.
    Abiding by the prevailing professional norms also would have led counsel to investigate
    more fully other mitigating evidence.              The ABA Guidelines clearly established that an
    investigation into mitigating evidence “should comprise efforts to discover all reasonably
    available mitigating evidence.” 1989 ABA Std. 11.4.1(C). Among the witnesses who should be
    interviewed are “witnesses familiar with aspects of the client’s life history that might affect . . .
    11This    case is thus unlike Pike v. Gross, 
    936 F.3d 372
    , 381–82 (6th Cir. 2019), in which an expert had
    tested the petitioner for brain damage prior to the sentencing phase and failed to find any signs of brain damage.
    Rogers’s counsel failed ever to have an expert evaluate him for signs of brain damage.
    No. 19-5427                             Rogers v. Mays                                    Page 30
    possible mitigating reasons for the offense(s), and/or other mitigating evidence to show why the
    client should not be sentenced to death.” 
    Id. 11
    .4.1(D)(3)(B). Further, “Counsel should ensure
    that all reasonably available mitigating and favorable information consistent with the defense
    sentencing theory is presented to the sentencing entity or entities in the most effective possible
    way.” 
    Id. 11
    .8.2(D). Likewise, the 1992 Tennessee Association of Criminal Defense Lawyers
    Manual instructed that the defense team “must investigate . . . the client’s entire life, including a
    search for all relevant institutional records and any individuals with information relevant to your
    client’s life and your theory of mitigation.” R. 119-14 (Manual at 4.4) (Page ID #16336).
    The defense team was aware that further investigation would likely yield significant
    mitigating evidence, including evidence of abuse. See R. 118-20 (O’Brien Rep. at 9–20) (Page
    ID #14835–46). The defense team knew of at least 57 potential mitigation witnesses whom they
    failed ever to contact. 
    Id. at 26
     (Page ID #14852). For example, they failed to contact Rogers’s
    biological father, Johnny Michelli, despite their knowledge that he—and not Laze Rogers—was
    likely Rogers’s biological father and that Rogers suffered from a range of mental illnesses that
    could have hereditary components. R. 119-1 (Einstein Decl. ¶ 9) (Page ID #14907). They also
    failed to interview witnesses who could have painted a fuller picture of the abuse, violence, and
    trauma that Rogers endured throughout his life. See R. 118-20 (O’Brien Rep. at 26–32) (Page ID
    #14852–58).
    When the defense team did contact witnesses, they failed to develop a strategy for
    presenting the witness testimony or prepare their witnesses. The lawyers did not work with the
    investigator to decide which witnesses would testify. R. 119-1 (Einstein Decl. ¶ 12) (Page ID
    #14907). As a result, witnesses felt that they were not prepared to testify. R. 111-5 (Page Decl.
    ¶ 52) (Page ID #13166); R. 113-7 (Miller Decl. ¶¶ 13–14) (Page ID #13721); R. 119-1 (Einstein
    Decl. ¶ 19) (Page ID #14908–09). Witnesses also felt that counsel had not given them the
    opportunity to explain the relevant evidence. See R. 112-6 (Sam Roger Decl. ¶ 120, 122) (Page
    ID #13596); R. 112-8 (Laze Rogers Decl. ¶ 71) (Page ID #13610).
    Trial counsel “knew that the successful presentation of mitigation was crucial to securing
    Mr. Rogers a sentence less than death.” R. 119-4 (Warner Decl. ¶ 14) (Page ID #14922); see
    also R. 123-4 (Gentry Decl. ¶ 7) (Page ID #24100). They were likewise aware that their
    No. 19-5427                             Rogers v. Mays                                    Page 31
    mitigation case was poor. See R. 119-1 (Einstein Decl. ¶ 21) (Page ID #14910) (mitigation
    narrative “lacked structure” and “there was no sense of a larger story”); R. 123-4 (Gentry
    Decl. ¶ 11) (Page ID #24102) (mitigation investigation was “incomplete, inaccurate and . . .
    undeveloped”).    The failure to investigate further “resulted from inattention, not reasoned
    strategic judgment.” Wiggins, 
    539 U.S. at 526
    . At this juncture, we cannot say which of this
    evidence was properly before the federal habeas court, and we do not decide this issue.
    Nonetheless, the record that the district court considered contained overwhelming evidence that
    counsel’s mitigation efforts were deficient.
    (2) Prejudice Prong
    Likewise, the record before the district court clearly revealed that Rogers was prejudiced
    by counsel’s deficient performance. “[P]rejudice exists if there is a reasonable probability that,
    but for his counsel’s ineffectiveness, the jury would have made a different judgment about
    whether [Rogers] deserved the death penalty as opposed to a lesser sentence.” Andrus, 140 S.
    Ct. at 1885–86. This inquiry “will necessarily require a court to ‘speculate’ as to the effect of the
    new evidence—regardless of how much or how little mitigation evidence was presented during
    the initial penalty phase.” Sears v. Upton, 
    561 U.S. 945
    , 956 (2010) (per curiam). “[B]ecause
    [Rogers’s] death sentence required a unanimous jury recommendation . . . , prejudice here
    requires only ‘a reasonable probability that at least one juror would have struck a different
    balance’ regarding [Rogers’s] moral culpability.” Andrus, 140 S. Ct. at 1886 (quoting Wiggins,
    
    539 U.S. at
    537–38).
    “[I]n order to establish prejudice, the new evidence that a habeas petitioner presents must
    differ in a substantial way—in strength and subject matter—from the evidence actually presented
    at sentencing.” Foust, 
    655 F.3d at 539
     (quoting Hill v. Mitchell, 
    400 F.3d 308
    , 319 (6th Cir.
    2005)). “[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.” Broom v. Mitchell,
    
    441 F.3d 392
    , 410 (6th Cir. 2006) (quoting Clark v. Mitchell, 
    425 F.3d 270
    , 286 (6th Cir. 2005)).
    Although the new evidence cannot be cumulative with the evidence that had been presented to
    the jury, the Supreme Court has made clear that it has “never limited the prejudice inquiry under
    No. 19-5427                                     Rogers v. Mays                                           Page 32
    Strickland to cases in which there was only ‘little or no mitigation evidence’ presented.” Sears,
    
    561 U.S. at 954
    .
    At the penalty phase, ten mitigation witnesses testified: Rogers’s sibling, Sam; Rogers’s
    presumed father, Laze Rogers; five other lay witnesses; a social worker; a psychologist; and a
    psychiatrist.    These witnesses testified that Rogers was severely abused as a child.                          This
    evidence, however, pales in comparison to the “tidal wave” of available mitigating evidence.
    Andrus, 140 S. Ct. at 1887. The mitigation evidence presented in the district court differed in
    strength and subject matter from the evidence that was presented at sentencing and, “rather than
    being cumulative . . . , provides a more nuanced understanding of [Rogers’s] psychological
    background and presents a more sympathetic picture of Rogers.” Jells v. Mitchell, 
    538 F.3d 478
    ,
    501 (6th Cir. 2008).12
    (a) Brain Damage
    The evidence of Rogers’s brain damage that was before the district court was
    substantially stronger than the evidence that was actually presented at the penalty phase of
    Rogers’s trial.       The district court learned that Rogers suffers from “neuropsychological
    impairments” that “significantly hinder his adaptive functioning in the real world, in that he is far
    less able to regulate his emotions, control his impulses, think quickly and efficiently, respond
    appropriately to changing stimulus demands, and consider long-term consequences of his
    actions.” R. 113-19 (James Report at 1) (Page ID #13952). The neuropsychological evaluation
    connected evidence of additional head injuries that contributed to these impairments, including,
    among others: “severe beatings by his stepfather that resulted in loss of consciousness on several
    occasions”; “a specific incident which occurred at the age of 10, when his stepfather hit him in
    the back of the head with an aluminum bat” causing him to “los[e] consciousness for about four
    12For  the purposes of analyzing whether this evidence is cumulative, we break up this evidence by subject
    matter, rather than going claim-by-claim. We do this for ease of analysis because many categories of evidence are
    relevant to multiple of Rogers’s claims. For example, various types of abuse impacted the mitigation narrative,
    shaped his experiences of complex trauma, and contributed to his brain damage. We note, however, that these
    claims are relevant in the context of counsel’s failure to present mitigation evidence in the four categories that
    Rogers lists in his habeas petition, which relate to: (1) the mitigation narrative; (2) the brain damage stemming from
    the torture that he suffered at the hands of his stepfather; (3) the complex trauma that he experienced; and
    (4) evidence regarding his biological father’s family.
    No. 19-5427                             Rogers v. Mays                                   Page 33
    hours,” “experience[] dizziness and poor balance for approximately two weeks after this
    incident,” and “have throbbing headaches”; and being “hit in the head by a metal bar during a
    prison riot” and “awaking . . . four to five days later.”      Id. at 3 (Page ID #13954).      The
    neuropsychological evaluation confirmed that Rogers’s history of abuse directly contributed to
    his neurological impairments. Id. at 10 (Page ID #13961).
    Testing also confirms that Rogers suffers from organic brain damage. Together, the
    behavioral imaging data and structural and functional imaging “converge to show abnormalities
    indicating brain damage . . . in regions that are very important for regulating behavior and
    emotions, communication, social cognition and conflict resolution.” R. 114-7 (Gur Report at 4)
    (Page ID #14032). The MRI and PET scans show multiple deficiencies that are clinically
    significant; these deficiencies are not independent of each other but interact in a way that
    significantly impeded Rogers’s ability to regulate his behaviors. For example, the scans show
    that he has a damaged amygdala which “will misinterpret danger signals and when excited, will
    issue false alarms that require intact frontal components of the limbic system for modulation.”
    Id. His frontal lobe, however, is “unable to exercise control as a normal one would, because his
    ‘thinking brain’ is not only damaged but is already operating at full capacity in its hyper-vigilant
    state,” which makes it “unable to . . . act as the brakes on the primitive emotional impulses
    emanating from the amygdala when the limbic system reaches its activated stage.” Id. Because
    his brain’s default state is one of “hyper-vigilance,” it responds to situational demands with
    “increased limbic activity associated with reduced cortical activity,” leading to a “lower
    threshold for impulsive behavior and reduced capacity to consider its context.” Id. at 5 (Page ID
    #14033).
    The brain-damage evidence that was before the district court was not “‘merely
    cumulative’ of that already presented” during Rogers’s original sentencing. Broom, 
    441 F.3d at 410
    . No evidence of brain damage was presented to the jury at the penalty phase of Rogers’s
    trial. The only discussion of brain damage was Neilson’s statements that trauma “can have a
    profound impact and even a permanent impact in how the brain functions.” R. 25-14 (Tr. at 272)
    (Page ID #5544) (emphasis added). This testimony, however, was presented purely in the
    abstract, and there was no evidence that Rogers did suffer any such brain damage. The evidence
    No. 19-5427                                    Rogers v. Mays                                           Page 34
    of brain damage presented to the district court thus differed “in a substantial way—in strength
    and subject matter—from the evidence actually presented at sentencing.” Broom, 
    441 F.3d at 410
     (quoting Clark, 
    425 F.3d at 286
    ); see also Sears, 
    561 U.S. at 956
    ; Rompilla v. Beard,
    
    545 U.S. 374
    , 392–93 (2005).
    (b) Evidence of Abuse
    Likewise, Rogers presented to the district court additional significant evidence of the
    abuse that Rogers suffered that was not merely cumulative. This included evidence of abuse that
    Rogers suffered at juvenile facilities, evidence of sexual abuse, and additional evidence of
    physical abuse.
    Rogers was confined at three different institutions in his adolescence: Mizpah’s Home
    for Boys (age 12); LTI (age 16); and Oakley Correctional Facility (age 17). Although Guin
    testified about the conditions at LTI generally and that Rogers witnessed abuse there, no
    evidence at the penalty phase showed (1) that Rogers directly experienced significant abuse at
    LTI; or (2) that Rogers both suffered and witnessed significant abuse at the other two
    institutions.13 As a result, evidence showing that Rogers experienced this abuse was not merely
    cumulative. It likewise differed significantly in strength and subject matter from the testimony
    that his stepfather abused him because it showed that Rogers was under constant threat of abuse
    and endured abuse that was different in kind from what his stepfather inflicted.
    13He     did, however, experience such abuse. Rogers presents evidence that, at Mizpah, Rogers and the other
    boys were badly beat as punishment, leaving “welts” and “real dark bruises.” R. 114–16 (LaPointe Decl. at ¶ 5)
    (Page ID #14117–18). An individual who had been confined there with Rogers “remember[ed] that the Reverend
    constantly beat one kid for wetting his bed” and “believe[d] that kid was Glenn.” Id. ¶ 7 (Page ID #14118). Rogers
    also offers witness testimony that, at LTI, the guards beat Rogers “quite a few times,” and Rogers was sent to the
    infirmary twice. Id. ¶ 21 (Page ID #14119). The abuse at LTI was far beyond what Guin described to the jury: the
    guards beat the boys with shovel handles and chains, made them strip and whipped them. Id. ¶¶ 20–21 (Page ID
    #14119). Physical and sexual abuse were common, and, among the other abuse, Rogers witnessed a group of boys
    setting another boy on fire at night. Id. ¶¶ 20–37 (Page ID #14119–22). He suffered further abuse at Oakley:
    someone with whom Rogers ran away reported that, while at Oakley, he “witnessed and heard boys rape and beat
    other kids . . . at least three times a week.” R. 115-15 (Barrett Decl. ¶ 6) (Page ID #14206).
    No. 19-5427                                   Rogers v. Mays                                           Page 35
    Further, counsel presented little evidence of sexual abuse at trial.14 Yet, such evidence is
    significant. Rogers was often in the same room as Sam during the times that their stepfather’s
    brother repeatedly sexually abused Sam. R. 112-6 (Sam Roger Decl. ¶ 78) (Page ID #13589);
    see also id. ¶¶ 70, 73–77 (Page ID #13588–89); R. 113-4 (Dempsey Decl. ¶¶ 35–36) (Page ID
    #13700). Another aunt allowed her boyfriend to sexually abuse Sam. R. 112-6 (Sam Roger
    Decl. ¶ 114) (Page ID #13595). This evidence is particularly relevant because multiple witnesses
    described Sam as Rogers’s protector and a parental figure to Rogers. Rogers may also have
    suffered sexual abuse directly: Sam suspected that a neighbor who sexually abused her also
    sexually abused Rogers. Id. ¶ 6 (Page ID #13578).
    Finally, additional evidence of physical abuse that was before the district court was
    sufficiently different from the evidence of physical abuse that was presented at trial so as not to
    be cumulative. At trial, there was evidence that Rogers’s stepfather beat him and chained him to
    his bed. First, additional evidence before the district court showed that his stepfather had further
    sadistic tendencies, such as breaking their pet dog’s neck, R. 112-6 (Sam Roger Decl. ¶ 43)
    (Page ID #13584), and inflicted violent beatings beyond the scope of what had been described to
    the jury, id. at 6 (Sam Roger Decl. ¶ 30) (Page ID #13582) (“I saw Big Danny beating Glenn
    with a tether pole. Glenn’s face was nearly unrecognizable because of all of the blood.”).
    Second, the evidence presented to the jury painted a picture in which Rogers’s stepfather was
    abusive, and his mother did not intervene. Evidence that suggested his mother—and not just his
    stepfather—abused him was not merely cumulative. See R. 112-6 (Sam Roger Decl. ¶ 48) (Page
    ID #13585); R. 111-5 (Page Decl. ¶ 29) (Page ID #13162).
    (c) Evidence of Mental Illness
    Additional evidence of mental illness that the district court heard was likewise not merely
    cumulative. This included evidence of a significant family history of mental illness, Rogers’s
    history of depression, and accounts of Rogers’s multiple personalities.
    14There   were only four pieces of evidence related to sexual abuse presented at the penalty phase:
    (1) Sam’s testimony that Sam suspected Rogers’s stepfather forcibly gave Rogers enemas, R. 25-13 (Tr. at 133–36)
    (Page ID #5404–07); (2) a possible reference by Rogers’s aunt to sexual abuse (no audible answer was transcribed),
    R. 25-15 (Tr. at 26) (Page ID #5684); and (3) Neilson’s and Caruso’s passing references to their understanding that
    Rogers suffered sexual abuse. R. 25-14 (Tr. at 260) (Page ID #5532); R. 25-16 (Tr. at 158) (Page ID #5822).
    No. 19-5427                              Rogers v. Mays                                 Page 36
    Although evidence of Rogers’s mental illness was presented to the jury at the mitigation
    phase of his trial, no evidence showed a significant family history of mental illness. This family
    history includes history on Rogers’s father’s side. The defense did not present any evidence that
    Johnny Michelli was Rogers’s biological father. R. 111-22 (Michelli Decl. ¶ 1) (Page ID
    #13392). His father’s side of the family has an extensive history of severe mental-health issues,
    including bipolar disorder, schizoaffective disorder, various personality disorders, schizophrenia,
    anxiety, depression, paranoia and drug addiction. Id. ¶¶ 48–51 (Page ID #13402–03); R. 116-15
    (Connie Michelli Medical Report at 3) (Page ID #14423); R. 116-16 (Connie Michelli Disability
    Determinations at 4) (Page ID #14428); R. 116-25 (Angela Michelli Psychological Consult)
    (Page ID #14500–03); R. 117-4 (Allen Michelli Sentencing Hr’g at 135–36) (Page ID #14541–
    42). His sibling Sam also suffered from significant mental illness that, in many ways, paralleled
    what Rogers suffered. Sam had multiple suicide attempts, both in childhood and adulthood, and
    has been confined in multiple mental hospitals. R. 112-6 (Sam Roger Decl. ¶¶ 88–94) (Page ID
    #13591–92). Like Rogers, Sam suffers from Dissociative Identity Disorder and has multiple
    identities and blackouts. Id. ¶¶ 94–97 (Page ID #13592). Unlike the evidence that was actually
    presented at the penalty phase of Rogers’s trial, this evidence showed that Rogers’s mental
    illnesses are part of a long family history.
    Additionally, the district court was presented with evidence of Rogers’s depression and
    history of suicidal thoughts that was not merely cumulative. This evidence showed that Rogers
    suffered significant depression and suicidal thoughts from the time he was a child. See R. 112-6
    (Sam Roger Decl. ¶ 25) (Page ID #13581) (significant depression around the age of nine);
    R. 113-12 (LTI Progress Notes at 1) (Page ID #13815) (suicidal thoughts as a teenager). This
    evidence was different in strength and subject matter from the testimony that Neilson gave at
    trial:   that he diagnosed Rogers with depressive disorder, but “wasn’t sure that [Rogers’s]
    depression had been chronic enough” to qualify as dystonic disorder, meaning that he was not
    sure it had been “pretty consistent for at least two years.” R. 25-14 (Tr. at 295) (Page ID #5567).
    Significant, nearly lifelong depression was substantially different from the type of depression
    that Neilson explained to the jury.
    No. 19-5427                             Rogers v. Mays                                   Page 37
    Finally, the evidence presented to the district court about Rogers’s different personalities
    was not cumulative with Neilson’s diagnosis of dissociative disorder not otherwise specified. At
    the penalty phase, Neilson stated that Rogers dissociates and showed an example of a letter that
    Rogers wrote saying he has other personalities. R. 25-14 (Tr. at 300–04) (Page ID #5572–76).
    There was no evidence, however, of what these other personalities looked like or how they acted
    differently. Such evidence is substantially different from Neilson’s clinical description of an
    unspecified dissociative disorder. Evidence that shows the scope of these different personalities
    and how these personalities acted would thus not have been cumulative. See 112-6 (Sam Roger
    Decl. ¶¶ 99–100) (Page ID #13593); R. 112-8 (Lazarus Rogers Decl. ¶¶ 48, 54) (Page ID
    #13606–08); R. 116-4 (Paul Sandifer Decl. ¶¶ 5–17) (Page ID #14313–14); R. 116-5 (Veronica
    Sandifer Decl. ¶¶ 4– 11, 15–17) (Page ID #14316–17).
    The district court had before it overwhelming evidence that these claims were substantial.
    A court able to consider that evidence could have no doubt that trial counsel’s investigation into
    this mitigation evidence was deficient or that trial counsel’s failure to investigate the avalanche
    of mitigating evidence prejudiced Rogers.       Throughout his childhood, Rogers experienced
    unimaginable abuse at the hands of nearly every adult who was supposed to be responsible for
    him. As a result of abuse, complex trauma, and significant head injuries, Rogers suffers from
    serious brain damage. We would be hard pressed to envision a more compelling mitigation
    narrative, and if we were evaluating the record before the district court, we would have no doubt
    that an adequate investigation into and presentation of the available mitigation evidence would
    have shaped the jury’s assessment of the aggravating and mitigating factors.
    Again, however, in light of Shinn v. Ramirez, we do not decide whether this ineffective-
    assistance claim is substantial. Instead, we vacate the aspects of the district court opinion with
    respect to the mitigation claims. Our grant of habeas corpus at the penalty phase on Claim C.12
    (ineffective assistance for failing adequately to challenge the semen evidence) entitles Rogers to
    resentencing in state court, and resentencing eliminates the need for the district court to consider
    the mitigation claims on remand.
    No. 19-5427                             Rogers v. Mays                                   Page 38
    3. Opening the Door to Evidence of Prior Escape (Claims E.12–13)
    Rogers next argues that counsel was ineffective in presenting evidence from Dr. Mark
    Cunningham at the penalty phase because Cunningham’s testimony opened the door to otherwise
    inadmissible evidence related to Rogers’s prior escape from prison and the potential for future
    escape. This claim was not presented in state court. The Martinez-Trevino exception does not
    excuse Rogers’s procedural default with respect to this claim because it is not substantial.
    Cunningham’s testimony focused on “the area of risk assessment with capital convicts.”
    R. 25-16 (Tr. at 188) (Page ID #5852). Before Cunningham testified, outside the presence of the
    jury, the court made clear that counsel was aware of the implications of permitting Cunningham
    to testify. The trial court stated that “it opens up the counter strike, so to speak.” Id. at 200
    (Page ID #5864).     The prosecution stated, “if they want to talk about there is no future
    dangerousness in prison, the possibility of not being in prison is also an issue that should be
    raised,” and the court clarified it would “let them have a wide open cross examination.” Id. at
    201 (Page ID #5865). The prosecution further stated that they would “be asking their expert . . .
    have you reviewed [Rogers’s] prison records from Florida Department of Corrections” and
    whether he is “aware that [Rogers] has a felony escape conviction from a Florida prison.” Id.
    The court asked defense counsel, “I assume y’all know about that too?” and defense counsel
    replied “Yes, I have seen that.” Id.
    Despite this risk, counsel chose to call Cunningham as a witness and ask about the risk of
    future dangerousness. During the post-conviction hearing, counsel testified that the purpose of
    introducing this testimony was to show that Rogers was unlikely to be violent in the future
    because future dangerousness was a mitigating factor under the federal statutes at the time. R.
    26-9 (Tr. at 129) (Page ID #8200).
    The Strickland standard is “highly deferential,” Strickland, 
    466 U.S. at 689
    , and “counsel
    is strongly presumed to have rendered adequate assistance and made all significant decisions in
    the exercise of reasonable professional judgment.” 
    Id. at 690
    . “[S]trategic choices made after
    thorough investigation of law and facts relevant to plausible options are virtually
    unchallengeable.” 
    Id.
    No. 19-5427                            Rogers v. Mays                                 Page 39
    In this case, counsel’s strategy “did not work out as well as hoped” but that does not
    mean “that counsel was incompetent.” Richter, 
    562 U.S. at 109
    . As a result, Rogers failed to
    show that his claim is substantial such that it falls within the Martinez-Trevino exception to
    procedural default.
    4. Ineffective Assistance of Counsel at Motion-for-a-New-Trial Stage (Claim F.3)
    Finally, Rogers argues that his counsel was ineffective by failing to raise certain
    arguments in the motion for a new trial. Those arguments pertain to both the guilt/innocence
    phase and the penalty phase. Rogers never raised this claim in state court, and it was thus
    procedurally defaulted. The Martinez-Trevino exception can excuse procedural default when a
    petitioner claims that trial counsel was ineffective. Martinez, 
    566 U.S. at 17
    . It cannot apply,
    however, when a petitioner claims that appellate counsel was ineffective. Davila v. Davis, 
    137 S. Ct. 2058
    , 2064 (2017). Neither the Sixth Circuit nor the Supreme Court has addressed
    whether the Martinez-Trevino exception can apply when the underlying ineffective assistance
    occurred in a motion for a new trial.
    Several courts have addressed whether the Martinez-Trevino exception applies to
    ineffective-assistance-of-post-sentencing-counsel claims, but these courts have arrived at
    different answers. The Third Circuit held that, on federal habeas review, a federal court may
    consider a defaulted claim that a post-sentencing lawyer was ineffective.         Richardson v.
    Superintendent Coal Twp. SCI, 
    905 F.3d 750
    , 756 (3d Cir. 2018). The Third Circuit reasoned
    that “the line dividing trial from appeal falls naturally at the notice of appeal” and because
    “[p]ost-sentencing motions precede the notice of appeal, . . . they fall on the trial side of the
    line.”    
    Id.
       The Third Circuit further explained that “[s]entencing and post-sentencing
    proceedings also differ categorically from appeals” because “[c]ounsel direct sentencing and
    post-sentencing arguments to the same trial court,” and post-sentencing counsel “may also
    develop the record by proffering new evidence, which the trial court may hear at an evidentiary
    hearing.” 
    Id. at 761
    . It also determined that the equitable principles in Martinez apply when the
    underlying ineffective-assistance claim relates to a post-sentencing proceeding because “[m]any
    states do not entertain ineffective-assistance claims on direct appeal.” 
    Id. at 762
    . Declining to
    apply the Martinez-Trevino exception to these claims would thus “prevent state and federal
    No. 19-5427                             Rogers v. Mays                                    Page 40
    courts from ever looking at meritorious ineffective-assistance-of-post-sentencing-counsel
    claims.” 
    Id.
    In contrast, the Fifth Circuit and several district courts in this circuit have arrived at the
    opposite answer. In a nonprecedential opinion and without further analysis, the Fifth Circuit
    held that a federal court could not hear a petitioner’s claim that “appellate counsel was
    ineffective for failing to raise [certain claims], in a motion for new trial or on direct appeal,”
    Milam v. Davis, 733 F. App’x 781, 782 (5th Cir. 2018) (per curiam), because “the Supreme
    Court has held that Martinez does not extend to ineffective assistance of appellate counsel
    claims,” 
    id.
     at 786 (citing Davila, 137 S. Ct. at 2065). Likewise, several district courts in this
    circuit have found that Martinez does not apply to IAC claims related to a motion for a new trial.
    See Johnson v. Genovese, No. 3:18-cv-00539, 
    2021 WL 3269954
    , at *18 (M.D. Tenn. July 30,
    2021) (Martinez-Trevino exception did not apply to claim of ineffective assistance of counsel
    when counsel omitted arguments from a motion for a new trial because it was a “claim[] of post-
    trial ineffectiveness”); Petty v. Hampton, No. 3:18-cv-00576, 
    2020 WL 3964207
    , at *17 (M.D.
    Tenn. July 13, 2020) (explaining that “Martinez does not apply because this entire claim
    concerns the alleged ineffective assistance of counsel in connection with a motion for a new
    trial” because a convicted and sentenced defendant is no longer presumptively innocent and
    because Martinez should be not read overly broadly). Although at least one court has mentioned
    that it is “unclear” if the Martinez-Trevino exception applies to claims that counsel was
    ineffective during the motion for a new trial, Esposito v. Humphrey, No. 5:12-cv-163, 
    2014 WL 7003770
    , at *34 (M.D. Ga. Dec. 10, 2014), several other district courts have suggested that this
    exception does not apply in this context, see Reese v. Liberty, No. 1:13-cv-00077-NT, 
    2018 WL 442998
    , at *12 (D. Me. Jan 16, 2018) (“The limited exception in Martinez does not apply to
    Petitioner’s claims of ineffective assistance in the motion for a new trial, which the Law Court
    has characterized as a post-conviction motion.”); Bourdon v. Goings, No. 15-cv-138-LM, 
    2016 WL 7480266
    , at *2 (D.N.H. Nov. 30, 2016) (Martinez exception does not apply to ineffective-
    assistance claims related to a motion for a new trial because a “motion for a new trial is properly
    characterized as a ‘post-conviction’ proceeding that is ‘collateral’ in nature for the purposes of
    § 2254(i)”).
    No. 19-5427                               Rogers v. Mays                                 Page 41
    We are persuaded by the Third Circuit’s analysis and hold that, in Tennessee, the
    Martinez-Trevino exception can excuse procedural default when the underlying claim relates to
    ineffective assistance of counsel at the motion-for-a-new-trial stage.
    First, as the Third Circuit explained was true in Pennsylvania, motions for a new trial in
    Tennessee courts “differ categorically from appeals.” Richardson, 905 F.3d at 761. In a motion
    for a new trial, the court may allow new testimony from witnesses. Tenn. R. Crim. P. 33(c)(1).
    Motions for a new trial go before the same court that presided over the trial. See id. 33(a).
    These similarities suggest that claims stemming from a motion for a new trial are more similar to
    claims that trial counsel was ineffective than claims that appellate counsel was ineffective.
    Second, as the Third Circuit explained, the notice of appeal is the appropriate transition
    point between trial and appeal. In Tennessee, the filing of a notice of appeal is addressed jointly
    by the Rules of Criminal Procedure and the Rules of Appellate Procedure. See Tenn. R. Crim. P.
    37(d)(1) (instructing the defendant to “file a timely notice of appeal with the clerk in accordance
    with Rule 4(a), Tennessee Rules of Appellate Procedure); Tenn. R. App. P. 3–4. A motion for a
    new trial is treated as separate from the appeals process. See Fahey v. Eldridge, 
    46 S.W.3d 138
    ,
    141 (Tenn. 2001) (“[I]n order to preserve errors for appeal, the appellant must first bring the
    alleged errors to the attention of the trial court in a motion for a new trial.”).
    Additionally, the equitable considerations that guided the decisions in Martinez and
    Trevino apply with equal force to ineffective-assistance claims related to a motion for a new trial.
    The Supreme Court recognized that the situation in Martinez necessitated an exception to ensure
    that the underlying ineffective-assistance claim “will have been addressed by one court.”
    566 U.S. at 11. Davila used this ground to differentiate ineffective-assistance-of-trial-counsel
    claims from ineffective-assistance-of-appellate-counsel claims, explaining that, unlike in an
    ineffective-assistance-of-trial-counsel claim, when a claim relates to ineffective assistance of
    appellate counsel, “at least ‘one court’ will have considered the [underlying trial error] on the
    merits.” 137 S. Ct. at 2067 (quoting Martinez, 
    566 U.S. at 11
    ). This is because if “trial counsel
    preserved the error by properly objecting,” but appellate counsel dropped the ball, then “that
    claim of trial error ‘will have been addressed by . . . the trial court.” 
    Id.
     (quoting Martinez,
    
    566 U.S. at 11
    ). But “[i]f an unpreserved trial error was so obvious that appellate counsel was
    No. 19-5427                                       Rogers v. Mays                                              Page 42
    constitutionally required to raise it on appeal, then trial counsel likely provided ineffective
    assistance by failing to object to it in the first instance,” and “the prisoner likely could invoke
    Martinez or Coleman to obtain review of trial counsel’s failure to object.” 
    Id.
     at 2067–68.
    If the Martinez exception does not apply to claims that counsel was ineffective on a
    motion for a new trial in Tennessee, certain claims may never be heard. This is because, in
    Tennessee, motions for a new trial are the preferred procedural mechanism for bringing trial
    errors to the attention of the trial court. To preserve an issue for appellate review, trial counsel 15
    not only must raise an objection at trial but also must renew that objection to the trial judge in a
    motion for a new trial within thirty days of sentencing. Tenn. R. App. P. 3(e); Tenn. R. Crim. P.
    33(b); State v. Harbison, 
    539 S.W.3d 149
    , 164–65 (Tenn. 2018) (“Grounds not raised in a
    motion for a new trial are waived for the purposes of appeal.”). The Tennessee Supreme Court
    has recognized that motions for a new trial ensure “that the trial judge might be given an
    opportunity to consider or to reconsider alleged errors committed during the course of the trial or
    other matters affecting the jury or the verdict . . . which either occurred after the trial or could not
    reasonably have been discovered until after the verdict.” McCormic v. Smith, 
    659 S.W.2d 804
    ,
    806 (Tenn. 1983). Motions for a new trial in Tennessee preserve the trial objections and are the
    mechanism by which trial counsel are expected to allow the “trial court” to address claims of
    “trial error.” See Davila, 137 S. Ct. at 2067. If counsel is ineffective at this stage, all trial issues
    will be waived. Tenn. R. App. 3(e); see also Harbison, 539 S.W.3d at 164. Accordingly,
    applying the Martinez-Trevino exception to ineffective-assistance claims at the Tennessee
    motion-for-a-new-trial stage in this context is necessary to ensure that all of a defendant’s trial
    claims can be heard in at least one court.
    The counterarguments are not persuasive. First, the district court repeatedly emphasized
    the Martinez exception is “narrow.” Rogers IV, 
    2019 WL 1331035
     at *100–01, 116. Davila
    cautioned against expanding Martinez to other types of claims. 137 S. Ct. at 2067. We are not,
    however, expanding the Martinez-Trevino’s exception to a new category of cases. Rather, we
    15As  we explained in Sutton, “[i]n a typical Tennessee case, it is likely that trial counsel will file the motion
    for new trial because Tennessee requires appointed trial counsel to continue representation throughout a defendant's
    direct appeal, and permits withdrawal only on a showing of good cause.” 745 F.3d at 793 (footnote omitted) (citing
    Tenn. Sup. Ct. Rule 13(e)(5); 
    Tenn. Code Ann. § 40-14-205
    (a)).
    No. 19-5427                             Rogers v. Mays                                   Page 43
    are clarifying that claims of ineffective assistance at the Tennessee motion-for-a-new-trial phase
    fit neatly within the larger bucket of trial claims, which are already recognized as within the
    scope of the Martinez-Trevino exception.
    Additionally, the district court suggested that the Martinez-Trevino exception does not
    apply in this circumstance because, at the motion-for-a-new-trial stage, a defendant no longer is
    presumed innocent. Rogers IV, 
    2019 WL 1331035
    , at *101; see, e.g., Johnson v. Genovese,
    
    2021 WL 3259954
    , at *18; Petty, 
    2020 WL 3964207
    , at *17. The Martinez-Trevino exception,
    however, indisputably applies to cases involving ineffective assistance at the sentencing phase.
    See Trevino, 569 U.S. at 417–18 (applying Martinez in a case involving ineffective assistance at
    the penalty phase of a trial). Yet, the presumption of innocence does not apply at the sentencing
    phase because “[o]nce the defendant has been convicted fairly in the guilt phase of the trial, the
    presumption of innocence disappears.” Delo v. Lashley, 
    507 U.S. 272
    , 278 (1993) (per curiam).
    Trevino thus illustrates that a defendant’s presumptive innocence is not determinative of whether
    the Martinez-Trevino exception may apply.
    In a state such as Tennessee, the Martinez-Trevino exception applies to claims that
    counsel was constitutionally ineffective on a motion for a new trial. Unlike with some of
    Rogers’s other claims, the claims related to ineffective assistance of counsel at the motion-for-a-
    new-trial stage relate to both the guilt/innocence phase and to the penalty phase. Thus, although
    our grant of habeas corpus at the penalty phase on Claim C.12 entitles Rogers to resentencing
    and means that, on remand, the district court need not consider any other issues related to the
    penalty phase, it must still resolve those issues that pertain to the guilt/innocence phase. On
    remand, the district court should evaluate whether Rogers presented a substantial claim and
    satisfies the remaining factors needed to excuse his procedural default. If so, the district court
    should proceed to resolve the claim of ineffective assistance on the motion for a new trial.
    III. CONCLUSION
    For the reasons articulated above, we AFFIRM the district court’s denial of habeas with
    respect to Rogers’s sufficiency-of-the-evidence claims (Claims G.39, I.5, I.8–11), claims
    regarding the exclusion of cross-examination and evidence regarding prior sexual acts between
    No. 19-5427                             Rogers v. Mays                                  Page 44
    the victim and her brother (Claims G.21–24, G.26, G.44), and claims that counsel was ineffective
    by opening the door to evidence of prior escape (Claims E.12–13). We REVERSE the district
    court’s denial of habeas on Rogers’s claim that trial counsel’s failure adequately to challenge the
    semen evidence was constitutionally ineffective (Claim C.12) and REMAND with instructions
    to grant habeas on this claim as to the penalty phase. We VACATE the district court’s findings
    that Rogers failed to overcome his procedural default on (1) his claims that counsel was
    ineffective in failing to investigate the victim’s brother as a source of the semen (Claims C.8,
    D.26) and (2) his mitigation claims (C.20–23, E.2–5). Finally, we REVERSE the district court’s
    finding that the Martinez-Trevino exception cannot excuse the procedural default when the
    underlying ineffective assistance occurred in a motion for a new trial and REMAND with
    instructions to determine whether Rogers can overcome his procedural default of this claim
    (Claim F.3).

    II.C.2.b, and otherwise concurring.
    I do not agree that Rogers was prejudiced at the penalty-phase by counsel’s failures
    regarding the sperm evidence. In assessing prejudice under Strickland v. Washington, 
    466 U.S. 668
     (1984), we determine whether, but for counsel’s ineffectiveness, the likelihood of a different
    outcome would have been “substantial, not just conceivable.” Harrington v. Richter, 
    562 U.S. 86
    , 112 (2011).
    Rogers has not shown that there was a “substantial” likelihood that the jury would have
    imposed a different penalty if counsel had been effective in challenging the quality of the sperm
    evidence or the source of the sperm. Even assuming that some combination of the washing-
    machine/Jeremy evidence and the additional serological evidence would have affected the rape
    conviction,1 the evidence could not have disturbed the jury’s verdict convicting Rogers of
    felony-murder-in-perpetration-of-kidnapping, with which the conviction for felony-murder-in-
    perpetration-of-rape was merged. R. 24-5 (Order) (Page ID #1142). And, as the majority
    acknowledges, disturbing the rape conviction would not eliminate the four statutory aggravating
    factors that the jury found in Rogers’s case, only one of which is required to impose the death
    penalty. 
    Tenn. Code Ann. § 39-13-204
    (i) (1996). And while the majority argues that there is a
    “reasonable probability” the jury might have weighed the factors differently without a formal
    rape conviction—admittedly the most powerful aggravating fact—the jury would still have been
    confronted with the premeditated and calculating kidnapping and murder of a 9-year-old whose
    shirt had been removed and whose shorts contained sperm in the inside crotch—albeit from an
    1I note that neither the additional serological evidence nor the Jeremy evidence would have rendered the
    sperm evidence inadmissible. As the state court noted, the new evidence would have only impacted the “weight” of
    the sperm evidence. Rogers III, No. M2010-01987-CCA-R3-PD, 
    2012 WL 3776675
    , at *47 (Tenn. Crim. App.
    Aug. 30, 2012).
    No. 19-5427                             Rogers v. Mays                                  Page 46
    unknown source. These facts, in and of themselves, and without conclusive evidence of rape, are
    highly inflammatory and disturbing.
    Further, the jury knew that the serology evidence was largely inconclusive and could not
    be directly tied to Rogers, Rogers III, 
    2012 WL 3776675
    , at *46, but sentenced Rogers to death
    anyway. 
    Id. at *47
    . Although it is “conceivable” that the new evidence further weakening the
    sperm evidence could have persuaded the jury to render a different penalty, I cannot agree, on
    these facts and with the statutory aggravating factors undisturbed, that the likelihood of a
    different penalty was “substantial” but for counsel’s errors. Harrington, 
    562 U.S. at 112
    .
    Finally, regarding sections II.C.1 and II.C.2.b, I am in complete agreement with the
    majority’s assessment of the evidence introduced for the first time in district court on Martinez-
    Trevino review of the claims of IAC at the penalty phase. Nevertheless, the Supreme Court’s
    recent decision in Shinn v. Ramirez, 
    142 S. Ct. 1718
    , 1734 (2022), bars our consideration of this
    evidence, as compelling as it may be.
    I concur in the majority opinion in all other respects.
