    COLLOTON, Circuit Judge.
    Ray Dansby was convicted by an Arkansas jury on two counts of capital
    murder and sentenced to death. After the district court denied his second amended
    petition for a writ of habeas corpus, this court vacated the dismissal of two claims and
    remanded for further consideration. Dansby v. Hobbs, 
    766 F.3d 809
    , 841 (8th Cir.
    2014). In the first claim, Dansby alleged that the state trial court had violated his
    Sixth Amendment right to confront witnesses against him. In the second, he alleged
    that the prosecution had engaged in misconduct. On remand, the district court denied
    Dansby’s petition with respect to his conviction but granted relief with respect to his
    sentence of death. We conclude that no relief is warranted, and therefore affirm in
    part and reverse in part.
    I.
    This court has considered Dansby’s case before, and our discussion of the
    background is drawn largely from those decisions. As summarized by the Arkansas
    Supreme Court, see Dansby v. State, 
    893 S.W.2d 331
     (Ark. 1995), the evidence at
    trial showed that on the morning of August 24, 1992, Dansby arrived at the residence
    of his ex-wife, Brenda Dansby, in El Dorado, Arkansas. Justin Dansby, their
    eight-year-old son, was in the living room with Ronnie Kimble, Brenda’s boyfriend.
    Justin was home with a cold and watching television, while Kimble was asleep on the
    couch. Brenda had left earlier to buy orange juice for Justin, and when she returned
    home, she was confronted by Dansby as she pulled her car into her driveway. Dansby
    twice ordered her to leave her car, and she eventually complied. Justin testified at
    trial that he saw Dansby hold Brenda “like a shield” before shooting her in the arm
    and in the neck.
    -2-
    Greg Riggins, a neighbor from across the street, also offered an account of
    Brenda’s death. According to his trial testimony, Riggins went to his front door after
    hearing gunshots and witnessed Dansby and Brenda struggling with a revolver. He
    then saw Dansby knock Brenda down, get the gun from her, and shoot two
    consecutive rounds into her from two or three feet away. Brenda tried to rise, and
    Dansby fired again, although Riggins believed the shot missed. After pausing for five
    or six seconds, Dansby shot Brenda once more, and her body went flat.
    Justin testified that Dansby then entered the home and shot Kimble in the chest.
    Kimble nonetheless was able to retrieve his own gun from beneath the couch. Kimble
    positioned himself behind the couch and attempted to return fire, but his gun
    produced only “clicking noises.” Dansby chased Kimble to the back of the house,
    and Justin heard about five more shots. When Justin went to investigate, he saw his
    father standing over Kimble, kicking him twice and then saying something Justin
    could not remember. Justin accompanied his father outside the house, where he saw
    his mother, motionless, with “blood all over her neck.” Dansby and Justin walked
    down the road, and after they separated, Justin called the police.
    El Dorado police officers arrived at Brenda’s home to find her body outside.
    They also found an injured Kimble on the floor of the back bedroom, along with a
    jammed .38 automatic pistol lying under him. Kimble eventually died of his wounds
    at a local hospital, but not before telling a police detective that Ray Dansby had shot
    him.
    Later the same day, a police officer encountered Dansby, who said, “I’m Ray
    Dansby. Y’all are looking for me.” The officer then took Dansby to the police
    station, where another officer advised Dansby of his rights. Dansby stated that he had
    left the scene with two guns, a .32 revolver and a .38 revolver, but had disposed of
    them where the police would never find them. By Dansby’s account, he had armed
    himself before traveling to Brenda’s home because he knew both she and Kimble had
    -3-
    handguns. Dansby explained that he had entered the front door to Brenda’s home to
    find Kimble holding a handgun in his right hand “pointed down.” Dansby stated that
    after an argument, “I just pulled my gun and started shooting.”
    At trial, prosecutors presented several pieces of evidence beyond the
    eyewitness testimony of Justin Dansby and Greg Riggins. An autopsy revealed
    gunshot wounds near Brenda’s left ear and on her upper chest. Similar wounds were
    found on Kimble’s chest, right arm, left upper back, and behind his left ear;
    superficial wounds were present on his left flank. The prosecution also presented
    testimony that Dansby was scheduled to appear in court on charges of second-degree
    assault and contempt of court at 9:00 a.m. on the day of the murders. State
    prosecutors brought those charges after Brenda had provided them with a signed
    affidavit alleging that Dansby assaulted her.
    Also testifying for the prosecution was Dansby’s jail cellmate Larry McDuffie,
    the boyfriend of Dansby’s half-sister. McDuffie said that Dansby admitted in jail that
    he had murdered Kimble and Brenda. Dansby told McDuffie he was “just glad” that
    Brenda was dead. According to McDuffie, Dansby recounted the following series of
    events: Dansby first shot Kimble after they “had words” about Brenda’s refusal to
    withdraw the assault charges. Kimble staggered backward into the house. Dansby
    then shot Brenda as she reached into her purse. Dansby followed Kimble into the
    house, and shot him several more times. When Dansby exited the house, he found
    that Brenda was still alive. In response to Brenda’s pleas for mercy, Dansby
    answered, “Well, b—, you done f—ed up cause I’m not gonna leave you out here in
    these streets when I done killed this man inside,” and then shot her once more.
    A jury convicted Dansby of two counts of capital murder, and sentenced him
    to death on both counts. The Arkansas Supreme Court affirmed the conviction and
    sentence. Dansby, 
    893 S.W.2d at 333
    . Dansby petitioned for postconviction relief
    under Arkansas Rule of Criminal Procedure 37. The trial court denied the petition,
    -4-
    and the Arkansas Supreme Court affirmed. Dansby v. State, 
    84 S.W.3d 857
     (Ark.
    2002).
    Dansby filed a petition for a writ of habeas corpus in the district court under
    
    28 U.S.C. § 2254
    . The district court denied relief on all claims and dismissed the
    petition. The court then denied Dansby’s motion to alter or amend the judgment. The
    district court granted a limited certificate of appealability, and this court expanded the
    certificate to encompass all claims that the district court had determined to be
    procedurally defaulted. We affirmed the district court’s decision in part, but vacated
    the dismissal of two claims and remanded for further consideration of those claims.
    Dansby, 766 F.3d at 841. In the first claim, Dansby alleged that the state trial court
    violated his Sixth Amendment right to confront witnesses against him. In the second,
    he alleged that the prosecution violated his due-process rights by withholding
    material exculpatory evidence and knowingly permitting false testimony.
    On remand, the district court denied relief with respect to Dansby’s conviction
    but granted relief from the death sentence and ordered the State to stipulate to a
    sentence of life imprisonment. The court determined that Dansby’s prosecutorial-
    misconduct claim was procedurally defaulted or, in the alternative, without merit.
    The court concluded, however, that the state trial court had violated Dansby’s
    constitutional right to confront witnesses against him. The court ruled that the
    violation was harmless with respect to Dansby’s conviction, but reasoned that “the
    error had a substantial and injurious effect” on the sentence. Both parties have
    appealed.
    II.
    The claims at issue concern the trial testimony of Larry McDuffie. Dansby
    argues first that the state trial court deprived him of his Sixth Amendment right to
    -5-
    confront witnesses against him by limiting his opportunity to cross-examine
    McDuffie and to introduce extrinsic evidence to impeach him.
    A.
    The parties dispute whether our review of Dansby’s confrontation claim is
    subject to the strictures of the Antiterrorism and Effective Death Penalty Act of 1996
    (“AEDPA”). AEDPA limits when a federal court may grant relief on a claim that was
    “adjudicated on the merits” in state court. 
    28 U.S.C. § 2254
    (d). Dansby asserts that
    the Arkansas Supreme Court did not adjudicate his claim on the merits.
    The Arkansas Supreme Court reviewed a ruling of the state trial court. After
    Dansby was arrested for murder, he was incarcerated with McDuffie in Union
    County, Arkansas. McDuffie was in jail after his arrest on a pending felony drug
    charge. Before trial, the prosecution moved in limine for an order to preclude the
    defense from “mentioning or attempting to elicit testimony from any witness
    regarding the reason for McDuffie’s incarceration, and pending charges or attendant
    matters.”
    The trial court ruled that charges that had been filed in the past against
    McDuffie that did not result in convictions were “clearly inadmissible and should not
    be referred to because the witness may not be impeached in that manner.” The court
    provided that Dansby could inquire whether McDuffie had served as a confidential
    informant for the El Dorado police department and whether he had been paid by the
    department for information in the past.
    Dansby sought additional leeway to elicit testimony designed to show
    McDuffie’s bias. In a brief and at a pretrial hearing, Dansby claimed that McDuffie
    had received special treatment from the State. He alleged that McDuffie had a history
    of working as an informant for local police, that he had been in and out of jail three
    -6-
    or four times in recent months, that the State’s treatment of previous criminal cases
    against him was inconsistent with its handling of other cases, and that he was not
    sanctioned for violating conditions of release.
    The trial court ordered that Dansby could inquire whether McDuffie had
    received promises of leniency or guarantees of immunity, but could not present
    evidence about “extrinsic matters which would call upon the jury to perform a feat of
    speculation or conjecture in order to relate it to [the] alleged bias.” If McDuffie
    denied or failed to admit facts that tended to show bias, however, then Dansby would
    be entitled to produce extrinsic evidence to rebut McDuffie’s testimony. The court
    cautioned that unless there was “direct evidence of an agreement of a promise of
    immunity or something along that nature,” Dansby would be “in the realm of
    speculation and conjecture.”
    The Arkansas Supreme Court upheld the trial court’s ruling. First, the court
    determined that the trial court correctly prevented Dansby from attacking McDuffie’s
    credibility based on evidence of prior criminal activity for which McDuffie had not
    been convicted. Dansby, 
    893 S.W.2d at 338
    . Second, the court reasoned that the trial
    court correctly allowed Dansby “to explore the area of bias” through cross-
    examination but not with extrinsic evidence. 
    Id. at 338-39
    . The court explained that
    a defendant had the right to prove facts by extrinsic evidence only if the witness
    denied or failed fully to admit pertinent facts. 
    Id.
     Finally, the court opined that
    Dansby’s proffered extrinsic evidence would have called for “the jury to perform a
    feat of speculation or conjecture” to connect it to the alleged bias. 
    Id. at 339
    .
    As a starting point, we presume that a state court has adjudicated a federal
    claim on the merits if the defendant presented the claim to the state court and the
    court denied relief. Harrington v. Richter, 
    562 U.S. 86
    , 99 (2011). This presumption
    applies even when the state court’s opinion does not expressly address the claim.
    Johnson v. Williams, 
    568 U.S. 289
    , 300-01 (2013).
    -7-
    Dansby has not rebutted the presumption of adjudication. Nothing in the
    opinion of the Arkansas Supreme Court suggests that it disposed of Dansby’s
    confrontation claim on procedural grounds. See Kenley v. Bowersox, 
    275 F.3d 709
    ,
    711 (8th Cir. 2002). Nor is it likely that the court “simply overlooked” the claim.
    Johnson, 
    568 U.S. at 300-01
    . In his briefing before the state supreme court, Dansby
    argued that the trial court did not give adequate weight to his confrontation rights
    when it limited the scope of his cross-examination. The Arkansas Supreme Court
    then affirmed the trial court’s decision, stating with approval that the ruling left
    Dansby free to explore “guarantees of immunity or promises of leniency,” as well as
    “the area of bias.” Dansby, 
    893 S.W.2d at 338-39
    . We think it highly unlikely that
    the court overlooked whether the trial court’s order adequately protected Dansby’s
    confrontation rights when it considered the precise limitations that Dansby challenged
    as unconstitutional.
    The materials cited by the Arkansas Supreme Court reinforce our conclusion.
    The court framed parts of its discussion in terms of Arkansas Rule of Evidence
    608(b). Rule 608(b) provides that a party may not prove specific instances of conduct
    through extrinsic evidence and may inquire into them on cross-examination only “if
    probative of truthfulness or untruthfulness.” Ark. R. Evid. 608(b). But the court then
    discussed Biggers v. State, 
    878 S.W.2d 717
     (Ark. 1994), which held that a particular
    application of Rule 608(b) did not violate a defendant’s constitutional right to
    confrontation. 
    Id. at 722
    . By relying on Biggers, the court in Dansby’s case
    demonstrated that it was addressing “a question with federal constitutional
    dimensions.” Johnson, 
    568 U.S. at 304-06
    . Accordingly, AEDPA governs our
    review of the state court’s decision to deny relief.
    B.
    Under AEDPA’s standard of review, the question is whether the Arkansas
    Supreme Court’s decision “was contrary to, or involved an unreasonable application
    -8-
    of, clearly established Federal law, as determined by the Supreme Court of the United
    States.” 
    28 U.S.C. § 2254
    (d). Dansby asserts that the state court’s treatment of his
    confrontation claim either was contrary to, or an unreasonable application of, three
    Supreme Court decisions: Olden v. Kentucky, 
    488 U.S. 227
     (1988); Delaware v. Van
    Arsdall, 
    475 U.S. 673
     (1986); and Davis v. Alaska, 
    415 U.S. 308
     (1974). In each of
    these cases, the Court held that “the trial court violated a defendant’s right to
    cross-examination by excluding evidence relatively likely ‘to show a prototypical
    form of bias on the part of’ a critical witness.” Sittner v. Bowersox, 
    969 F.3d 846
    ,
    851 (8th Cir. 2020) (quoting Van Arsdall, 
    475 U.S. at 680
    ).
    A decision is contrary to federal law if it (1) contradicts a rule set forth in the
    Supreme Court’s cases or (2) confronts a set of “materially indistinguishable” facts
    and arrives at a different result. Williams v. Taylor, 
    529 U.S. 362
    , 405-06 (2000). A
    decision unreasonably applies federal law if the “state court correctly identifies the
    governing legal standard but either unreasonably applies it to the facts of the
    particular case or unreasonably extends or refuses to extend the legal standard to a
    new context.” Munt v. Grandlienard, 
    829 F.3d 610
    , 614 (8th Cir. 2016). “To
    demonstrate an unreasonable application, a prisoner must show that a state court’s
    adjudication was not only wrong, but also objectively unreasonable, such that
    fairminded jurists could not disagree about the proper resolution.” Zornes v. Bolin,
    
    37 F.4th 1411
    , 1415 (8th Cir. 2022) (internal quotations omitted). “The more general
    the rule, the more leeway courts have in reaching outcomes in case-by-case
    determinations.” Yarborough v. Alvarado, 
    541 U.S. 652
    , 664 (2004).
    In Olden, Van Arsdall, and Davis, the Supreme Court recognized that
    “constitutional rights can trump evidentiary rules and privileges in some
    circumstances.” Sittner, 969 F.3d at 851. Yet those decisions also reaffirmed the
    principle that the right to cross-examine may “bow to accommodate other legitimate
    interests in the criminal trial process.” Chambers v. Mississippi, 
    410 U.S. 284
    , 295
    (1973). In each case, the Court acknowledged that a defendant’s opportunity for
    -9-
    cross-examination must be weighed against other concerns, including “harassment,
    prejudice, confusion of the issues, the witness’ safety, or interrogation that is
    repetitive or only marginally relevant.” Van Arsdall, 
    475 U.S. at 679
    ; see also Olden,
    
    488 U.S. at 232
    ; Davis, 
    415 U.S. at 316
    .
    The state trial court placed three limits on Dansby’s cross-examination of
    McDuffie. Two concerned the use of extrinsic evidence. To rebut McDuffie’s
    testimony with extrinsic evidence, Dansby was required to establish first that
    McDuffie denied facts on cross-examination that tended to show bias. Extrinsic
    evidence also could not invite “the jury to perform a feat of speculation or
    conjecture.” None of the cited Supreme Court decisions is contrary to this ruling.
    Olden, Van Arsdall, and Davis did not even concern the use of extrinsic evidence.
    Nor do they establish any principle that was applied unreasonably by the Arkansas
    court in limiting the use of extrinsic evidence. Indeed, the Supreme Court “has never
    held that the Confrontation Clause entitles a criminal defendant to introduce extrinsic
    evidence for impeachment purposes.” Nevada v. Jackson, 
    569 U.S. 505
    , 512 (2013)
    (per curiam) (emphasis removed). Thus, the Arkansas Supreme Court did not act
    contrary to, or unreasonably apply, clearly established federal law when it approved
    the trial court’s limitations on the use of extrinsic evidence.
    The other limitation concerned the scope of the cross-examination itself. The
    trial court instructed Dansby not to question McDuffie about past charges that did not
    result in convictions. The court clarified, however, that Dansby could inquire into
    “evidence of guaranties of immunity or promises of leniency or any other
    considerations.”
    At trial, Dansby did not make use of the latitude allowed by the trial court’s
    ruling. During cross-examination, McDuffie revealed that he had worked as an
    informant and reached a signed agreement with law enforcement. Yet Dansby did not
    develop a line of questioning about any special treatment that McDuffie may have
    -10-
    received in return for his cooperation. On this point, Dansby asked only three
    questions, and the trial court disallowed just one. The objectionable question
    concerned why McDuffie was held in jail at the time he implicated Dansby, but that
    question standing alone sought evidence about unadjudicated criminal activity that
    the trial court had properly ruled inadmissible. Dansby asked no questions
    concerning McDuffie’s treatment by law enforcement in the time between his release
    from jail and his trial testimony. Within the limits of the trial court’s ruling, Dansby
    was allowed to explore whether McDuffie continued to cooperate with law
    enforcement, whether he received preferential treatment in exchange, and whether he
    hoped to receive favorable treatment in return for his testimony. That Dansby did not
    question McDuffie on these matters is not attributable to the court’s ruling.
    The trial court recognized, on the one hand, the need to curb speculation and
    to avoid improper impeachment based on charges that did not result in convictions.
    On the other, the court considered Dansby’s right to elicit probative evidence of
    favorable treatment of McDuffie by law enforcement or the State. The court balanced
    these interests by permitting Dansby to inquire into the sources of McDuffie’s
    potential bias so long as he did not ask about past charges that did not result in
    convictions. If McDuffie failed to testify truthfully, then Dansby could rebut his
    testimony by presenting relevant extrinsic evidence. The Arkansas Supreme Court
    did not contravene, or unreasonably apply, the decisions in Olden, Van Arsdall, and
    Davis by concluding that the balance struck by the trial court was permissible under
    the Sixth Amendment. Accordingly, Dansby’s claim regarding the Confrontation
    Clause does not justify relief.
    III.
    Dansby next alleges that the prosecution withheld material exculpatory
    evidence, in violation of the rule in Brady v. Maryland, 
    373 U.S. 83
     (1963), and
    knowingly permitted McDuffie to testify falsely, in violation of Dansby’s right to due
    -11-
    process. See Napue v. Illinois, 
    360 U.S. 264
     (1959). These allegations are closely
    related. Dansby contends that the State concealed various unwritten inducements that
    the prosecution had offered to McDuffie in exchange for his testimony. These
    alleged inducements included a favorable sentencing recommendation in McDuffie’s
    pending felony drug case and non-enforcement of the conditions of his pretrial
    release. Dansby points to a statement purportedly signed by McDuffie in 2005,
    recanting his trial testimony and accusing the prosecution of directing him to testify
    in a manner that he told the authorities was not true.
    The district court concluded that Dansby had procedurally defaulted his
    Brady–Napue claim. Alternatively, the court decided that the claim was without
    merit. We agree that the claim is defaulted, and need not address the merits.
    A.
    Dansby argues that we should proceed directly to the merits because the State
    has waived its right to raise procedural default as a defense. Dansby contends that
    the State waived the defense by failing to present it adequately in response to
    Dansby’s second amended habeas petition.
    Dansby first presented his Brady–Napue claim in the second amended petition.
    The State responded by incorporating any arguments that it made in opposition to
    Dansby’s first claim in his two previous petitions. In its earlier responses, the State
    had asserted that Dansby’s first claim “was grounded solely in state law, and for that
    reason is defaulted.” The first claim in Dansby’s original and first amended petitions,
    however, concerned the Confrontation Clause, not Brady or Napue. This court
    concluded that the State’s incorporation of a previous argument on procedural default
    was insufficient to give Dansby notice of its position that the Brady–Napue claim, in
    particular, was procedurally defaulted. Dansby, 766 F.3d at 824-25.
    -12-
    The State now concedes that it forfeited an assertion of procedural default as
    to the Brady–Napue claim but denies that it strategically waived the defense. “A
    waived claim or defense is one that a party has knowingly and intelligently
    relinquished; a forfeited plea is one that a party has merely failed to preserve.” Wood
    v. Milyard, 
    566 U.S. 463
    , 470 n.4 (2012). A federal court retains discretion to
    address procedural default if the State inadvertently failed to present the issue. King
    v. Kemna, 
    266 F.3d 816
    , 822 (8th Cir. 2001) (en banc). In this case, the State’s
    attempt to raise a procedural-default argument through incorporation by reference,
    though ineffectual, did not signal its intent to waive the defense. Instead, it showed
    only that the lawyers made a mistake in fashioning the response. The district court
    had discretion to address procedural default after giving the parties proper notice.
    Dansby, 766 F.3d at 824; King, 
    266 F.3d at 821-22
    .
    B.
    A petitioner has procedurally defaulted a claim if he did not present the claim
    in state court and there are no remaining state remedies available. Skillicorn v.
    Luebbers, 
    475 F.3d 965
    , 976 (8th Cir. 2007). Dansby did not raise his Brady–Napue
    claim in state court, but he asserts that the claim is not defaulted because he has
    available to him a state remedy: the writ of error coram nobis. This writ permits the
    Arkansas Supreme Court to reinvest jurisdiction in a state circuit court to consider
    certain “errors of the most fundamental nature,” including the State’s withholding of
    material evidence. Howard v. State, 
    403 S.W.3d 38
    , 43 (Ark. 2012).
    The writ of coram nobis, however, is unavailable if Dansby failed to exercise
    due diligence in petitioning for relief. The Arkansas Supreme Court has “consistently
    held” that if a petitioner delays in pursuing relief, and lacks a valid excuse for that
    delay, the court may deny his petition “on that basis alone.” Henington v. State, 
    556 S.W.3d 518
    , 523 (Ark. 2018). “Due diligence requires that (1) the defendant be
    unaware of the fact at the time of trial; (2) the defendant could not have, in the
    -13-
    exercise of due diligence, presented the fact at trial; and (3) upon discovering the fact,
    the defendant did not delay bringing the petition.” 
    Id.
    By his own account, Dansby was aware before trial that McDuffie’s testimony
    supposedly was false. He asserts, however, that this awareness had no practical value
    without evidence to prove its falsity or knowledge of the agreement between
    McDuffie and the State. That contention rings hollow, because Dansby did not take
    reasonable steps to develop the evidence before trial. In the document furnished to
    Dansby’s counsel in April 2005, McDuffie stated:
    Nobody representing Ray ever talked to me about the case, either before
    the trial or at anytime until now. I was really surprised by that, I was
    waiting on the trial lawyers to come talk to me so I could tell them what
    I knew but they never contacted me.
    McDuffie’s expressed willingness to share “what [he] knew” before the trial shows
    that Dansby, through due diligence, could have uncovered evidence of McDuffie’s
    supposed agreement with the State by interviewing him before the trial. See Thomas
    v. State, 
    241 S.W.3d 247
    , 250 (Ark. 2006) (per curiam).
    In any event, after McDuffie’s purported recantation in April 2005, Dansby had
    the information that he needed to petition for a writ of error coram nobis. Yet he
    waited six years before bringing the statement to this court’s attention. Even now,
    after another decade has passed, Dansby has not sought coram nobis relief. In light
    of this delay, we conclude that the Arkansas Supreme Court would decline to reinvest
    jurisdiction in a circuit court to hear Dansby’s claim. See 
    id.
     (declining to reinvest
    jurisdiction when the petitioner waited “more than five years” without good cause
    before seeking coram nobis relief); see also Gordon v. State, 
    588 S.W.3d 342
    , 347
    (Ark. 2019) (affirming the denial of a petition for the same reason).
    -14-
    To avoid this conclusion, Dansby asserts that “pursuit of a claim in federal
    court satisfies the diligence requirement for coram nobis relief.” He relies on
    Newman v. State, 
    354 S.W.3d 61
     (Ark. 2009), where the Arkansas Supreme Court
    made a fact-specific determination that a prisoner and his counsel acted diligently by
    pursuing a claim in federal court. 
    Id. at 67-68
    . In that unusual case, the prisoner’s
    counsel attempted to initiate state proceedings under Arkansas Rule of Criminal
    Procedure 37 on the prisoner’s behalf. These efforts were thwarted by the prisoner,
    who was incompetent at the time, so his counsel pursued relief in federal court
    instead. 
    Id. at 68-69
    . Once federal habeas proceedings were initiated, the prisoner
    placed his newly discovered evidence front and center. See 
    id. at 64
    ; Newman v.
    Norris, 
    597 F. Supp. 2d 890
    , 895 (W.D. Ark. 2009). Although Newman did not
    petition for a writ of coram nobis in state court before pursuing his claim through a
    federal petition for habeas corpus, he diligently presented the newly discovered facts
    in a judicial forum.
    Dansby, by contrast, possessed McDuffie’s recantation for years without
    pressing it in any court. Six months after obtaining the recantation, Dansby filed a
    motion to expand the record in the district court that did not mention McDuffie’s
    written statement. Several years passed before he finally raised it. Without good
    cause for his delay, we conclude the Arkansas Supreme Court would not permit a
    state circuit court to entertain a petition for the writ of error coram nobis. Because
    Dansby has not alleged that any other state remedies are available to him, his claim
    is procedurally defaulted.
    C.
    A petitioner who has defaulted his claim may not present that claim through a
    habeas corpus petition unless he establishes both cause and prejudice. Clemons v.
    Luebbers, 
    381 F.3d 744
    , 750 (8th Cir. 2004). Dansby cannot show either.
    -15-
    To show cause, Dansby must demonstrate that his failure to comply with the
    state procedural rule was attributable to “some objective factor external to the
    defense.” Murray v. Carrier, 
    477 U.S. 478
    , 488 (1986). Because the State’s
    suppression of evidence is both a factor external to the defense and an element of a
    Brady claim, the claim sometimes may provide its own cause to excuse a procedural
    default. Hall v. Luebbers, 
    296 F.3d 685
    , 699 (8th Cir. 2002). But that rule obtains
    only where the State’s suppression of evidence is the reason for the petitioner’s
    default. See Henry v. Ryan, 
    720 F.3d 1073
    , 1082-83 (9th Cir. 2013). A petitioner has
    not shown cause if he “had evidentiary support for his claim” before his default, 
    id.,
    or if the evidence was “reasonably available through other means.” Zeitvogel v. Delo,
    
    84 F.3d 276
    , 279-80 (8th Cir. 1996).
    Dansby could have learned about McDuffie’s information by interviewing him
    before trial, and, at the latest, Dansby possessed the facts necessary to seek relief
    when he obtained McDuffie’s recantation in 2005. At that point, Dansby could have
    filed a petition in state court, or, at the very least, presented the new evidence in his
    federal habeas corpus proceeding. His failure to do so is attributable to him, rather
    than some external cause, and is therefore insufficient to excuse the procedural
    default.
    Even if Dansby could show cause, he also would have to establish prejudice
    by demonstrating that the allegedly suppressed McDuffie evidence is material to his
    conviction or sentence. Banks v. Dretke, 
    540 U.S. 668
    , 698-99 (2004). That is, there
    must be “a reasonable probability that, had the evidence been disclosed, the result of
    the proceeding would have been different.” Cone v. Bell, 
    556 U.S. 449
    , 469-70
    (2009).
    Dansby argues that the evidence was material because it would have allowed
    him to undermine the credibility of McDuffie’s trial testimony. See Napue, 
    360 U.S. at 269
    . But while Dansby says that McDuffie’s testimony was “unique,” the record
    -16-
    at the guilt phase shows otherwise. The most damaging portions of his testimony
    were cumulative of other evidence. See Strickler v. Greene, 
    527 U.S. 263
    , 293-96
    (1999). Eyewitnesses described how Ray Dansby shot both Brenda Dansby and
    Ronnie Kimble. Justin Dansby testified repeatedly that neither victim drew a gun
    before suffering a gunshot wound. Justin heard Dansby fire about five shots at
    Kimble as he tried to flee. According to Riggins, Dansby killed Brenda as she lay
    defenseless on the ground. Forensic evidence showed that Brenda and Kimble each
    suffered multiple gunshot wounds. Before he died, Kimble identified Ray Dansby
    as his killer. Dansby himself told police that after an argument, he “just pulled [his]
    gun and started shooting.” As we observed in a previous decision, “there was
    substantial evidence apart from McDuffie’s testimony that permitted a jury to infer
    that Dansby killed the victims in a premeditated and deliberate manner.” Dansby,
    766 F.3d at 817.
    As to the sentence, McDuffie’s testimony again was not as significant as
    Dansby suggests. During the penalty phase, the jury concluded that the evidence
    supported three aggravating circumstances. Two of those are undisputed and
    unrelated to McDuffie’s testimony: that Dansby had (1) committed a prior violent
    felony, and (2) created a risk of death or injury to someone other than the victims. As
    to the third aggravating circumstance—that the murders were “committed in an
    especially cruel or depraved manner”—McDuffie’s testimony bore only on the
    disjunctive alternative of depravity. Cruelty was established by testimony showing
    that Dansby intended to and did inflict mental anguish upon his victims by leaving
    them at least briefly uncertain as to their ultimate fate. 
    Ark. Code Ann. § 5-4-604
    (8);
    see Anderson v. State, 
    108 S.W.3d 592
    , 608 (Ark. 2003). The jury also found that
    Dansby’s evidence did not support the existence of any mitigating factor. We see no
    material connection between McDuffie’s testimony and the suggested mitigating
    factors, which concerned Dansby’s personal life and characteristics, criminal history,
    moral culpability, or subsequent cooperation with police. Where an error is alleged
    to have impacted only one of multiple aggravating factors, the absence of any
    -17-
    mitigating factors strongly suggests that any error was harmless. See Jones v. State,
    
    10 S.W.3d 449
    , 455 (Ark. 2000).
    We therefore conclude that Dansby’s claim based on Brady and Napue is
    procedurally defaulted, and that he has not demonstrated cause and prejudice to
    overcome the default. We need not address whether the district court properly
    deemed McDuffie’s recantation incredible without holding an evidentiary hearing,
    because no hearing is required where the petitioner’s allegations, even if true, fail to
    overcome a procedural default. See Amos v. Minnesota, 
    849 F.2d 1070
    , 1072 (8th
    Cir. 1988); Moormann v. Ryan, 
    628 F.3d 1102
    , 1114 (9th Cir. 2010).
    *       *       *
    For these reasons, we affirm the district court’s denial of relief on Dansby’s
    conviction, but reverse the grant of relief with respect to the sentence. The case is
    remanded with directions to dismiss the second amended petition for writ of habeas
    corpus.
