Davis v. Guerrero

Case: 24-70008 Document: 152-1 Page: 1 Date Filed: 06/25/2026 United States Court of Appeals for the Fifth Circuit United States Court of Appeals ____________ Fifth Circuit FILED No. 24-70008 June 25, 2026 ____________ Lyle W. Cayce Clerk Irving Alvin Davis, Petitioner—Appellant, versus Eric Guerrero, Director, Texas Department of Criminal Justice, Correctional Institutions Division, Respondent—Appellee. ______________________________ Appeal from the United States District Court for the Western District of Texas USDC No. 3:14-CV-121 ______________________________ Before Smith, Graves, and Engelhardt, Circuit Judges. Jerry E. Smith, Circuit Judge: Irving Davis raped and murdered 15-year-old Melissa Medina, cutting off her fingertips to prevent discovery of DNA evidence. In 2002, he was convicted of capital murder and sentenced to death before the Texas Court of Criminal Appeals (“CCA”) granted him a retrial for the sentencing phase. At resentencing, the state introduced evidence of Davis’s affiliation with Satanism, alongside personal writings and drawings, to assert that Davis was a future danger. Davis was again sentenced to death. His claim of a First Amendment violation for introducing evidence of his affiliation with Satan- Case: 24-70008 Document: 152-1 Page: 2 Date Filed: 06/25/2026 No. 24-70008 ism was denied on direct appeal by the CCA, and his claims of ineffective assistance of counsel (“IAC”) were rejected by the state habeas corpus court. The federal district court denied relief. We granted a certificate of appealability (“COA”). Because none of Davis’s claims can overcome AEDPA’s deferential standard of review, we affirm. I. In 2001, Medina and her friends gathered at Benjamin Romero’s house to drink and socialize; Davis was present as a friend of Romero’s. Davis told Romero he wanted to “hit up on Melissa” and tried to “dirty dance” behind Medina without her knowledge, attempting to place his geni- tals against her behind and rub them against her. Medina displayed indiffer- ence or distaste for Davis and tried to move away when he engaged in the aforementioned “dirty dancing.” The group at Romero’s house left to walk Medina home, but when she approached an elementary school yard that she normally cut across, she said she could make it home on her own. As the group dispersed, Davis said he wanted to walk Medina the rest of the way and ran after her. A woman living across the street from the schoolyard went outside when her dogs became agitated and stated she heard low growls followed by thumping noises and moaning. When Davis returned to Romero’s house, he had fresh scratches, which he claimed occurred as a byproduct of an alterca- tion with his mother. Davis left Romero’s house and walked toward the school, in the opposite direction of his home. Medina’s dead and naked body was found in the elementary school parking lot the following morning, wear- ing only an open bra. According to the autopsy, Medina was severely beaten and had suf- fered blunt-force trauma throughout her body, severe internal head injuries, and a ruptured pulmonary artery. She was strangled and suffered serious 2 Case: 24-70008 Document: 152-1 Page: 3 Date Filed: 06/25/2026 No. 24-70008 injuries to her vaginal area consistent with penile penetration. The medical examiner found that she had been sexually assaulted at the time of death and that her vaginal injuries were inconsistent with consensual sex. Medina’s fingertips had been cut off, and she had a gaping, cutting wound on her left wrist where Davis had made multiple attempts to sever her hand from her wrist. Davis originally lied to police about how he received the scratches on his neck and where he last saw Medina before admitting to killing her by strangulation. Davis claimed that they began having consensual sex and that he became surprised when she asked him to stop and told him that she would state that he had raped her if he told anyone that they had had sex. Davis then said that he became worried about going to jail and began choking her, continuing to strangle her with his belt, even after she passed out; he stated that he “blacked out.” Davis was convicted of capital murder and sentenced to death in 2002. He appealed the conviction, and the CCA affirmed his conviction but ordered a retrial for the punishment phase. Davis was again sentenced to death, and the CCA affirmed on direct appeal. At his resentencing trial, the state put on evidence that supported the claim that Davis was involved with Satanism, including books, personal writ- ings, and drawings found in his prison cell. The state also called Donald Haley as an expert on Satanism, who testified that various satanic texts advo- cated for destroying or sacrificing humans, which meant causing their death. The defense put on an expert, Joseph Melton, who claimed that Satan- ism as understood by the Church of Satan should not be taken literally. Davis also testified as to how he viewed his belief in Satanism, stating that his belief in Satan was symbolic and that Satanism advocated for non-violence. Davis’s defense largely focused on accountability while seeking to humanize Davis. 3 Case: 24-70008 Document: 152-1 Page: 4 Date Filed: 06/25/2026 No. 24-70008 After his second sentencing, Davis filed a postconviction habeas cor- pus petition; the state habeas trial court ruled against him on all counts. In 2014, the CCA adopted the state habeas trial court’s findings of facts and conclusions of law. After multiple amended federal habeas petitions and an abatement of federal habeas proceedings to file state law claims that were summarily dis- missed by the CCA, the federal habeas court denied Davis’s request for relief, finding that the claims were either procedurally defaulted or reasona- bly rejected by the state court. Davis received a COA from this panel on his assertion that his First Amendment rights were violated by the state’s admis- sion of evidence concerning his affiliation with Satanism and his IAC claims.1 II. Title 28 U.S.C. § 2254(d) provides that a habeas application “shall not be granted with respect to any claim that was adjudicated on the merits in State court proceedings unless the adjudication of the claim” resulted in a decision “that was contrary to, or involved an unreasonable application of, clearly established Federal law, as determined by the Supreme Court of the United States” or ”resulted in a decision that was based on an unreasonable determination of the facts in light of the evidence presented in the State court proceeding.” “This standard . . . is difficult to meet.” White v. Woodall, 572 U.S. 415, 419 (2014) (citation modified). “A state-court decision is ‘con- trary to’ clearly established federal law only if it ‘arrives at a conclusion oppo- site to that reached by [the Supreme] Court on a question of law or if’ it resolves ‘a case differently than [the Supreme] Court has on a set of mate- rially indistinguishable facts.’” Langley v. Prince, 926 F.3d 145, 155 (5th Cir. _____________________ 1 See generally Davis v. Guerrero, No. 24-70008, 2025 WL 1766785 (5th Cir. June 26, 2025) (per curiam) (unpublished). 4 Case: 24-70008 Document: 152-1 Page: 5 Date Filed: 06/25/2026 No. 24-70008 2019) (en banc) (quoting Williams v. Taylor, 529 U.S. 362, 413 (2000)). The unreasonable-application prong asks “whether it is ‘beyond the realm of pos- sibility that a fairminded jurist could’ agree with the state court.” Id. at 156 (quoting Woods v. Etherton, 578 U.S. 113, 118 (2016)). To succeed, “a state prisoner must show that the state court’s ruling on the claim being presented in federal court was so lacking in justification that there was an error well understood and comprehended in existing law beyond any possibility for fairminded disagreement.” Woodall, 572 U.S. at 419–20. “[I]f a habeas court must extend a rationale before it can apply to the facts at hand, then by definition the rationale was not clearly established at the time of the state-court decision.” Id. at 426 (citation modified). “We may not characterize . . . state-court factual determinations as unreasonable merely because we would have reached a different conclusion in the first instance. Instead, § 2254(d)(2) requires that we accord the state trial court substantial deference.” Brumfield v. Cain, 576 U.S. 305, 313–14 (2015) (citation modified). “If reasonable minds reviewing the record might disagree about the finding in question, on habeas review that does not suffice to supersede the trial court’s determination.’” Id. at 314 (citation modified). “Overcoming AEDPA’s relitigation bar is necessary but not sufficient to win habeas relief . . . . [T]he prisoner still must show, on de novo review, that he is in custody in violation of the Constitution or laws or treaties of the United States.” Langley, 926 F.3d at 156 (citation modified). III. To succeed on his First Amendment claim, Davis must first demon- strate that the CCA’s decision was contrary to or involved an unreasonable application of clearly established law or was based on an unreasonable factual determination. Davis fails to clear AEDPA’s bar under all three approaches. 5 Case: 24-70008 Document: 152-1 Page: 6 Date Filed: 06/25/2026 No. 24-70008 A. Regarding the requirements of AEDPA, Davis and the amici say much about freedom of religion. But neither Davis nor the amici point to clearly established law (and research has not revealed any) that addresses the rele- vance and admissibility of evidence as it relates to the First Amendment’s protection of religious liberty, especially not in the criminal context. Davis cites only Dawson v. Delaware, 503 U.S. 159 (1992), a First Amendment freedom-of-association case. The best that amici can muster is a series of Establishment Clause cases about courts’ resolving disputes con- cerning religious doctrine. Those cases are not analogous, as they do not speak to the criminal context, do not deal with the admissibility of evidence (as distinguished from general protection under the Constitution), and do not elucidate the issue in this case, which is not the orthodoxy of the Church of Satan, but whether Davis’s affiliation with Satanism is relevant such that it prevents the state’s evidence from running afoul of the First Amendment. 2 Because the Supreme Court has no clearly established law on the issue, the religious aspect of this case does not alter the analysis under AEDPA. 3 _____________________ 2 Davis claims that Dawson must be understood in the context of Supreme Court precedent that clearly establishes that an individual cannot be penalized for membership in a group if some members of the group engage in unlawful activities, absent proof that he specifically engaged in or intended to support the unlawful activities. Davis is incorrect because he is conflating the scope of protected conduct with the scope of evidence that a court may permissibly admit. As we explain, Dawson rejected the claim that the scope of admissibility is coextensive with the scope of constitutionally protected conduct. 3 That is not to say that there are no ways in which those issues could otherwise be implicated. For example, both Federal Rule of Evidence 403 and Texas Rule of Evidence 403 permit judges to exclude evidence if, inter alia, it results in unfair prejudice or misleads the jury. Those rules could come into play when dealing with a religious issue, and Davis asserted them on direct appeal, but the CCA rejected that argument, and it is not before this court. Davis v. State, 329 S.W.3d 798, 805–06 (Tex. Crim. App. 2010). 6 Case: 24-70008 Document: 152-1 Page: 7 Date Filed: 06/25/2026 No. 24-70008 B. Davis focuses on Dawson as his source of clearly established law from the Supreme Court. In Dawson, the prosecution originally sought to introduce (1) expert testimony regarding the origin and nature of the Aryan Brotherhood, as well as the fact that Dawson had the words “Aryan Brotherhood” tattooed on the back of his right hand, (2) testimony that Dawson referred to himself as “Abad- don” and had the name “Abaddon” tattooed in red letters across his stomach, and (3) photographs of multiple swastika tattoos on Dawson’s back and a picture of a swastika he had painted on the wall of his prison cell. Id. at 161–62. But before the penalty phase, the parties agreed to introduce only this stipulation regarding the origin and nature of the Aryan Brother- hood: “The Aryan Brotherhood refers to a white racist prison gang that began in the 1960’s in California in response to other gangs of racial minori- ties. Separate gangs calling themselves the Aryan Brotherhood now exist in many state prisons including Delaware.” Id. at 162. In exchange for the stip- ulation, the state did not call an expert witness on the Aryan Brotherhood. The Supreme Court began by rejecting, as too broad, Dawson’s pro- posed rule that the Constitution forbids the consideration of evidence pro- tected by the First Amendment when making sentencing decisions. Id. at 164. The Court recognized that sentencing courts have broad discretion in what they consider so long as that material is relevant. Id. The Court nev- ertheless found that Dawson’s First Amendment rights had been violated, particularly with respect to his membership in the Aryan Brotherhood. Id. at 165. The Court stated that if the prosecution had introduced the expert testimony that it had originally proposed, it would be a “much different case”; but because the stipulation spoke only to on the racist beliefs of the Brotherhood and did not even tie such beliefs to the Delaware gang, the 7 Case: 24-70008 Document: 152-1 Page: 8 Date Filed: 06/25/2026 No. 24-70008 Aryan Brotherhood evidence was irrelevant. Id. at 166. More specifically, the Court reasoned that because “the prosecution did not prove that the Aryan Brotherhood had committed any unlawful or violent acts, or had even endorsed such acts, the Aryan Brotherhood evi- dence was also not relevant to help prove any aggravating circumstance.” Id. at 166. By way of caveat, however, the Court stated that the reason introduc- ing evidence of Dawson’s membership in the Aryan Brotherhood violated the First Amendment is that it “tended to prove nothing more than the abstract beliefs of the Delaware chapter.” Id. But the Court clarified that in many cases, associational evidence might serve a legitimate purpose in showing that a defendant represents a future danger to society. Id. In Dawson, how- ever, his First Amendment rights were violated “by the admission of the Aryan Brotherhood evidence . . . because the evidence proved nothing more than Dawson’s abstract beliefs.” Id. at 167. In rejecting Davis’s First Amendment claim, the CCA explained that to demonstrate the relevance of evidence concerning a defendant’s member- ship in a group, the state must show “(1) proof of the group’s violent and illegal activities, and (2) the defendant’s membership in the organization.” Davis v. State, 329 S.W.3d 798, 805 (Tex. Crim. App. 2010). The CCA noted that the state had introduced prison records showing that Davis had identi- fied himself as a Satanist since 2005 and had owned various Satanic religious publications that discussed rituals of destruction and human sacrifice and that various people “had committed murder and mutilation in the name of Satan.” Id. (citation modified). The court further found that though the de- fense expert, Melton, had debated what it meant to destroy someone in Sa- tanism, he acknowledged that some people had been killed in the name of Satanism. The CCA concluded, therefore, that it was “within the zone of reasonable disagreement for the trial court to decide that the evidence of Satanism was relevant to the issue of future dangerousness. Id. at 805–06. 8 Case: 24-70008 Document: 152-1 Page: 9 Date Filed: 06/25/2026 No. 24-70008 C. Davis begins by asserting that his case is materially indistinguishable from the facts of Dawson and that the CCA’s decision was thus contrary to clearly established law. Davis identifies Dawson’s key points as (1) the prose- cution’s failure to present evidence that this specific chapter of the Aryan Brotherhood committed illegal activities; (2) that the State invited the jury to infer that Delaware and California chapters held the same beliefs; and (3) that the Aryan Brotherhood evidence was not tied to the murder of Daw- son’s victim. Davis’s representation of the key factual predicates of Dawson is inaccurate and does not permit this court to displace the CCA’s decision under AEDPA. The failure of the prosecution to connect the Delaware and California chapters was important in Dawson, but the Court’s First Amend- ment holding does not rest on it; instead, that fact is highlighted by the Court to indicate another reason why the stipulation itself amounted to no evidence at all. The First Amendment violation at base in Dawson lay in the lack of relevance of the asserted information and the fact that it “tended to prove nothing more than the abstract beliefs of the Delaware chapter.” Dawson, 503 U.S. at 166. The factual overlay here is substantially different. In Dawson, the bare fact of associational membership was at issue. This case is materially distinguishable from Dawson because the prosecution adduced substantial evidence that Davis, by way of his brand of Satanism, harbored views that were relevant to future dangerousness. Here, there were multiple writings and drawings from Davis that demonstrated that his affilia- tion with Satanism was relevant to future dangerousness. For the situation in Dawson to be factually analogous, Delaware would have needed to try prov- ing that Dawson was a future danger because he was a violent white suprem- acist, with reference to his collection of white supremacist literature and writ- ings that advocated for violence. As is made apparent by the example, the factual scenario differs in material ways between this case and Dawson; Davis 9 Case: 24-70008 Document: 152-1 Page: 10 Date Filed: 06/25/2026 No. 24-70008 cannot demonstrate that the state court decision was contrary to clearly established law. 4 D. Davis asserts that Dawson clearly establishes that for evidence of a defendant’s group affiliation to be admissible without violating the First Amendment, there must, at a minimum, be “proof of the group’s violent and illegal activities.” As to the question of upholding the CCA’s decision under AEDPA, the CCA cites this as the on-point rule for deciding relevance inquiries with regard to aggravating circumstances under the First Amend- ment. Our AEDPA deference to the CCA’s ruling will stand or fall based on the reasonableness of its application of that rule here. The CCA’s application of Dawson was not objectively unreasonable. It was not even clear error. 5 Even if Dawson establishes that there must be proof of violence or illegal activity on the part of the group in question, it does not clearly establish what the quality or quantity of that evidence must be or how such groups must be conceptualized; instead, Dawson establishes only that the individual must be a part of that group. Dawson does not define what it means for a group to commit or en- dorse “unlawful or violent acts.” As a result, a fairminded jurist could con- clude that Dawson is satisfied where a court finds that some individuals who _____________________ 4 This is a non-exhaustive list of distinctions between the cases. For example, the state in Dawson did not just fail to provide evidence of the Delaware chapter; it provided no evidence whatsoever of the violent practice or endorsement of violent practices by any Aryan Brotherhood group, much less the Delaware group. Dawson, 503 U.S. at 162. Texas here provided evidence of the group’s violent tendencies. 5 See Woods v. Donald, 575 U.S. 312, 316 (2015) (“[A]n ‘unreasonable application of’ those holdings must be objectively unreasonable, not merely wrong; even clear error will not suffice.”). 10 Case: 24-70008 Document: 152-1 Page: 11 Date Filed: 06/25/2026 No. 24-70008 are a part of the group endorsed violations of the law, as distinguished from its being an official organizational position. Dawson, 503 U.S. at 165–66. Though it is true that this permits “associational guilt” in some broad sense, Dawson does not even clearly establish that such a concern is relevant when it comes to admissibility. 6 In finding that evidence of some Satanists committing violence was sufficient, the CCA construed the group at a high level of generality, consis- tent with the state’s approach at trial, and in a way that was not forbidden by clearly established law in Dawson or any other case Davis points to. 7 Impor- tantly, that evidence does, in fact, do more than demonstrate the abstract beliefs of Satanists, as it is and was used as evidence that Davis represents a future danger owing to the substance of the beliefs and what they mean for Davis as an actor in the world. Unlike in Dawson, the evidence was not adduced just because the jury could think that Satanism is unpalatable in and of itself, but to indicate that Davis’s adherence to Satanist views increased the likelihood that he would be a danger to society. Likewise, the prosecu- tion’s expert’s literalist reading of the Satanic Bible did not, as in Dawson, _____________________ 6 For example, if the Aryan Brotherhood endorsed or committed violent acts, and Dawson claimed he was a member of that organization (not because he believed such acts were good or because he even committed such acts but because he was seeking protection in prison), the fact of his membership would remain admissible as evidence of aggravating circumstances under Dawson because he was a member of a group that engaged in and advocated for violence. 7 Davis points again to First Amendment caselaw, some of which Dawson cites and some of which it does not, for the proposition that an individual cannot be penalized for membership in a group if some members of the group engaged in or intended to support unlawful activities. But under AEDPA, those cases clearly establish very little as it relates to Davis because Dawson explicitly rejects the contention that an activity’s being constitu- tionally protected categorically precludes its admissibility. See Dawson, 503 U.S. at 165 (“We therefore conclude that the Constitution does not erect a per se barrier to the admis- sion of evidence concerning one's beliefs and associations at sentencing simply because those beliefs and associations are protected by the First Amendment.”). 11 Case: 24-70008 Document: 152-1 Page: 12 Date Filed: 06/25/2026 No. 24-70008 invite the jury to infer the abstract beliefs of Satanists but asserted that Satanist literature that Davis owned endorsed violence, as highlighted by his conclusion that “to destroy” someone means to kill him. That is sufficient under Dawson and is enough to satisfy AEDPA’s deferential standard. 8 The permissibility of the CCA’s reasoning is also apparent on the face of Dawson itself. In the same paragraph where the Court castigates Delaware for failing to prove that the Aryan Brotherhood had done anything unlawful or even endorsed such acts, it states the following: Delaware might have avoided this problem if it had presented evidence showing more than mere abstract beliefs on Daw- son’s part, but on the present record one is left with the feeling that the Aryan Brotherhood evidence was employed simply because the jury would find these beliefs morally reprehensible. Because Delaware failed to do more, we cannot find the evi- dence was properly admitted as relevant character evidence. Dawson, 503 U.S. at 167. Far from clearly establishing the boundaries of the relevance inquiry in the First Amendment context, Dawson left open the possibility that Delaware could have avoided the constitutional violation if the evidence had demonstrated something more than the defendant’s abstract beliefs. Under AEDPA, such a statement is sufficient to grant state courts broader latitude in how they apply the law. 9 The CCA’s finding that the state’s producing plausible evidence is _____________________ 8 See Dawson, 503 U.S. at 166 (stating that proving the Aryan Brotherhood had endorsed violent acts could be sufficient to permit admission of the contested evidence). 9 See, e.g., Yarborough v. Alvarado, 541 U.S. 652, 664 (2004) (“[E]valuating wheth- er a rule application was unreasonable requires considering the rule's specificity. The more general the rule, the more leeway courts have in reaching outcomes in case-by-case deter- minations.”); Woodall, 572 U.S. at 422–23 (discussing how the Court’s reservation of a legal point in Mitchell v. United States was sufficient to indicate that a state court decision was not objectively unreasonable.). 12 Case: 24-70008 Document: 152-1 Page: 13 Date Filed: 06/25/2026 No. 24-70008 sufficient was also reasonable under relevant law because, as even Davis ac- knowledges, Dawson can be reasonably interpreted as requiring only that the prosecution provide proof of an association’s unlawful tendencies. 10 The state provided such proof when its expert testified that people had committed violence in the name of Satan. Davis’s suggestion that the decision concerning relevancy must lie with the judge, not the jury, does nothing to change the preceding analysis. Neither the state nor this court asserts that the issue of relevancy must lie with the jury. Instead, all we suggest is that once evidence is relevant, the meaning of that relevant evidence as it pertains to the defendant is a question for the jury in the context of Dawson. 11 With Fuller in mind, it becomes appar- ent that though the judge must make the relevance determination, the jury is still significant to the inquiry and a fair-minded jurist applying Dawson could conclude as the CCA concluded. E. Davis asserts that the CCA made an unreasonable finding of fact when it determined that Davis belongs to a group that engages in or advocates for violent and illegal activities based on Haley’s testimony that some members of the religion advocate for violence. Davis claims it is undisputed that he was an adherent of the Church of Satan and its non-violent ideals, but as pre- viously highlighted that is not the case. Because the actual nature of Davis’s relationship with Satanism was not undisputed or established as a fact, it was _____________________ 10 See Fuller v. Johnson, 114 F.3d 491, 498 (5th Cir. 1997) (reasoning that the state satisfied Dawson because it introduced evidence of gang membership and the gang’s violent track record). 11 See Fuller, 114 F.3d at 498 (finding no Dawson violation because “[a] reasonable juror could conclude that membership in such a gang is relevant to future danger- ousness.”). 13 Case: 24-70008 Document: 152-1 Page: 14 Date Filed: 06/25/2026 No. 24-70008 reasonable for the CCA to conclude that Davis belonged to a group that endorsed or encouraged violence. Likewise, it was not unreasonable for the CCA to rely on Haley’s interpretation merely because another expert and Davis himself testified that the language in the Satanic texts were symbolic. Davis’s assertions are a straightforward attempt to relitigate the case, and AEDPA forbids us from taking that step on this record. Consequently, Davis cannot be granted relief under any of his asserted standards. 12 F. Even if, arguendo, Davis had overcome AEDPA’s bar, any error was harmless under Brecht v. Abrahamson, 507 U.S. 619 (1993). A habeas peti- tioner can prevail only if the error had “substantial and injurious effect or influence in determining the jury’s verdict.” Id. at 637. At the COA stage, we concluded that at least Davis’s drawings and writings would be admissible, and the issue of Brecht is resolved by the admis- sibility of Davis’s writings and drawings alone. Davis, 2025 WL 1766785, at *6. His writings show a frequent preoccupation and antipathy toward humanity in general, including several instances in which he wishes to enact some level of physical violence on others. The discussion of Satanism is also invariably comingled with other content, and among his writings are hand- written reproductions of the Satanic Rules, which include the noted issue of “destroying someone.” Some of his drawings display violent and sexually _____________________ 12 Davis claims that his Eighth Amendment and Fourteenth Amendment rights were violated by being sentenced to death on the basis of constitutionally protected relig- ious beliefs. At the COA stage, Davis suggested that his Eighth and Fourteenth Amend- ment claims were never addressed by any court; we declined to remand because he “does not make any developed argument that those claims are not encompassed within his Daw- son claim.” Davis, 2025 WL 1766785, at *7 n.13. Even assuming arguendo that his Eighth and Fourteenth Amendment challenges were proper because we reject his Dawson claim, we also reject those assertions. 14 Case: 24-70008 Document: 152-1 Page: 15 Date Filed: 06/25/2026 No. 24-70008 explicit content, such as a drawing of a crying woman who is bound, gagged, and nearly naked and a drawing of woman with a slashed throat. As the COA panel stated, the drawings and writings “exhibit[ed] a preoccupation with rape, violence (particularly towards women), and death.” Id. Because those materials were admissible on their own, the bare fact of Davis’s association with Satanism―the thing that Dawson purportedly protects―would likely be beneficial, not prejudicial, to Davis, providing him an opportunity to explain the metaphorical nature of his writings. The previous point alone should suffice, but when paired with the evidence of the crime itself, the series of testimonies concerning Davis’s past violent actions, Davis’s thorough cross-examination of Haley, Davis’s testi- mony concerning his views on Satanism, and the state habeas court’s finding that the jurors had been thoroughly questioned about their ability to rule fairly on Satanism, it becomes certain that Davis cannot satisfy Brecht. IV. Davis alleges that his defense counsel was deficient in violation of the Sixth Amendment. More specifically, he alleges that the state habeas court’s treatment of his claim under Strickland v. Washington, 466 U.S. 668 (1984), was an unreasonable application of clearly established law because it was predicated on an incorrect assumption that a capital defendant’s testimony absolves counsel of the duty to investigate adequately and because it pre- cluded a finding of prejudice based on aggravating facts alone. Davis also asserts that the state habeas court relied on an unconstitutional causal-nexus test and made an unreasonable determination of the facts in the state court record. A. In order to prevail on a Washington claim of IAC, “a petitioner has the 15 Case: 24-70008 Document: 152-1 Page: 16 Date Filed: 06/25/2026 No. 24-70008 burden of showing (1) deficient performance, that is, that his trial counsel’s performance ‘fell below an objective standard of reasonableness’; and (2) resulting prejudice, that is, that ‘there is a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different.’” Neal v. Vannoy, 78 F.4th 775, 789 (5th Cir. 2023) (quoting Wash- ington, 466 U.S. at 688, 694). “An attorney’s actions are deficient only if ‘no competent attorney’ would have taken the action counsel did.” Id. at 790 (quoting Premo v. Moore, 562 U.S. 115, 124 (2011)). When Washington is asserted under AEDPA’s deferential standard, the question is not whether counsel’s actions were reasonable but “whether there is any reasonable argu- ment that counsel satisfied” Washington’s deferential standard. Harrington v. Richter, 562 U.S. 86, 105 (2011). There is a reasonable argument that Davis’s counsel’s conduct satis- fied the Washington standard, so Davis’s IAC claim fails. Davis’s description of the state court’s decision as predicated on the assumption that a capital defendant’s decision to testify absolves counsel of the duty to perform a con- stitutionally adequate investigation is incorrect. In reality, the state habeas court found that Davis’s counsel adequately investigated the case before the 2008 retrial on punishment. Davis appears to be highlighting the fact that the state habeas court found that his decision to testify, and his occasional refusal to cooperate, influenced counsel’s trial strategy, even though, by trial counsel’s own admission, Davis did not agree to take the stand definitively until the day of (or shortly before that). That finding is a far cry from stating that the counsel had no mitigation responsibility. Davis spends very little time directly challenging the state habeas court’s findings of fact and even less time establishing what Supreme Court law clearly establishes. Instead, he made assertions as though the case were being reviewed de novo instead of under AEDPA’s deferential standard. None of the cases relied on makes it so clear that there was a dereliction of 16 Case: 24-70008 Document: 152-1 Page: 17 Date Filed: 06/25/2026 No. 24-70008 professional duty that no reasonable argument could be made that Washing- ton was satisfied. Davis’s strongest authority is Wiggins v. Smith, 539 U.S. 510 (2003), which held the following: In assessing the reasonableness of an attorney’s investigation, however, a court must consider not only the quantum of evi- dence already known to counsel, but also whether the known evidence would lead a reasonable attorney to investigate fur- ther. Even assuming Schlaich and Nethercott limited the scope of their investigation for strategic reasons, [Washington] does not establish that a cursory investigation automatically justifies a tactical decision with respect to sentencing strategy. Rather, a reviewing court must consider the reasonableness of the investigation said to support that strategy. Id. at 527. Davis focuses on the “further investigation” language to suggest that his counsel’s mitigation investigation was deficient because there were “red flags” that should have prompted further investigation. In Wiggins, however, the Court did not state that failure to investigate further red flags is a per se example of IAC; instead, the Court grounded any analysis in the “rea- sonableness of the investigation said to support that strategy.” Id. Addition- ally, the facts of Wiggins itself are a far cry from this case. In Wiggins, counsel did not prepare any social history on the defendant, even though the state gave him the funds to do so, because counsel sought instead to focus on re-con- testing the factual case. That is just not the factual situation here. The state habeas court found that Davis’s counsel did the following: 1. Conducted extensive investigation during the first trial be- fore deciding to do further investigations because of chang- ing circumstances. 2. Hired an investigator who they believed to be capable and competent enough to serve both as a fact investigator and a 17 Case: 24-70008 Document: 152-1 Page: 18 Date Filed: 06/25/2026 No. 24-70008 mitigation expert. 3. Had a large amount of client contact before the retrial and interviewed local family members including Davis’s moth- er between five and fifteen times. 4. Traveled to North Carolina for five days to interview witnesses. 5. Actively sought to find Davis’s father for an interview but could not recall interviewing him. 6. Discovered and presented evidence at trial that Davis’s father was abusive and provided Davis with an opportunity to develop those facts further. 7. Asked Davis about any sexual abuse he experienced in the past and presented that evidence at trial. 8. Asked Davis’s mother, grandmother, and uncle whether Davis’s father sexually abused any of his children and was given no indication that such abuse had occurred. 9. Developed a series of contingency plans based on whether Davis took the stand and asked for the death penalty. 10. Learned about Davis’s alleged suicide attempt, something the jury was privy to. 11.
