MEMORANDUM*
RON HAYNES, Superintendent of Stafford

Respondent-Appellee.
Appeal from the United States District Court
for the Eastern District of Washington
Stanley Allen Bastian, Chief Judge, Presiding
Argued and Submitted September 11, 2023
Seattle, Washington
Before: HAWKINS, W. FLETCHER, and R. NELSON, Circuit Judges.
Petitioner-Appellant Don Moore appeals the denial of his 28 U.S.C. § 2254
petition challenging his Washington state conviction for first-degree murder. We
have jurisdiction pursuant to 28 U.S.C. § 1291, and we affirm.

This disposition is not appropriate for publication and is not precedent
except as provided by Ninth Circuit Rule 36-3.
On state post-conviction review, the Washington state courts determined that
Moore’s trial counsel rendered ineffective assistance by failing to investigate his
history of mental illness, diagnosis of a 100% disability for combat-related PTSD,
brain abnormalities, and combined effect of complex medications he was taking at
the time of the homicide. The state court granted Moore’s petition as to his
sentence, finding that he was prejudiced at sentencing because he was unable to
request a downward sentence exception due to his mental health issues, and denied
the petition as to his underlying conviction.
Under the Antiterrorism and Effective Death Penalty Act (“AEDPA”), which
governs this petition, we may grant a claim adjudicated on the merits only if the
state court's decision was (1) “contrary to, or involved an unreasonable application
of, clearly established Federal law, as determined by the Supreme Court of the
United States,” or (2) “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).
Moore contends he received ineffective assistance of counsel because
evidence of his mental health could have supported a defense of diminished
capacity to form the requisite intent for premeditated murder and, in the alternative,
could have supported conviction of lesser-included offenses of second-degree
murder or manslaughter. An ineffective assistance claim requires Moore to prove:
(1) counsel's representation “fell below an objective standard of reasonableness,”
2
and (2) there is a reasonable probability that “but for counsel's unprofessional
errors, the result of the proceeding would have been different.” Strickland v.
Washington, 466 U.S. 668, 688, 694 (1984). The standards created by Strickland
and AEDPA are both highly deferential, and when applied in tandem the review is
doubly deferential. Harrington v. Richter, 562 U.S. 86, 105 (2011).
Rendering the “last reasoned [state court] decision,” the Washington
Supreme Court reasonably applied clearly established law in denying Moore relief
as to his conviction. See Tamplin v. Muniz, 894 F.3d 1076, 1086 (9th Cir. 2018).
Even acknowledging trial counsel’s deficient performance, it found that Moore
failed to show prejudice. See Strickland, 466 U.S. at 700. Although some record
evidence supports Moore’s diminishing mental health around the time of the
homicide—including his medical records demonstrating PTSD and brain disease,
cumulative effects resulting from medications, and his belief he was entitled to
conduct a citizen’s arrest as a “sheriff”—it was reasonable for the state court to find
no substantial likelihood of a different result given the strength of the evidence for
premeditation. Instead, the Washington Supreme Court considered Moore’s
additional evidence of two expert reports and found that neither supported a defense
of diminished capacity. See State v. Gough, 768 P.3d 1028, 1030 (Wash. App. Ct.
1989). As such, we cannot disturb the state court’s determination of its own
diminished capacity standard. See Bradshaw v. Richey, 546 U.S. 74, 76 (2005)

(“[A] state court's interpretation of state law . . . binds a federal court sitting in
habeas corpus.”) (citation omitted).
Mental impairment may have affected Moore in seeking out his victim, but
record evidence also contradicts Moore’s theory of the actual shooting. Physical
evidence shows Moore shot the victim from some distance (while the victim was
seated), and later stabbed him to make it appear as though there had been a close-
up struggle and that Moore manipulated the scene to support his story of a close
altercation. Thus, the state court’s determination was not an unreasonable
application of the facts under § 2254(d) based on the strength of the evidence for
premeditation.
Accordingly, we cannot say that the state court's conclusion “was so lacking
in justification that there was an error well understood and comprehended in
existing law beyond any possibility for fairminded disagreement.” Richter, 562
U.S. at 103.
AFFIRMED.
