Cowans v. Bagley, 639 F.3d 241

Cowans was convicted of murder in Ohio and sentenced to death by the trial court, following jury recommendation.
Ohio appellate and Supreme Court proceedings upheld the conviction and sentence on direct and collateral review.
Cowans filed a federal habeas petition under AEDPA; the district court denied relief but granted a COA on several claims, and the Sixth Circuit granted review on additional claims.
Key factual ties included Cowans' palm print at the scene, a bloodhound trace leading to his home, and Cowans' jailhouse confession with non-public details.
During trial and sentencing Cowans exhibited outbursts and refused to permit mitigating evidence; defense counsel faced several disputed decisions challenged in the habeas petition.
The court ultimately affirmed the denial of relief, deferentially reviewing state-court adjudications under AEDPA.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Mitigation waiver voluntary waiver	Cowans contends waiver of mitigating evidence was involuntary/unknowing.	State courts found waiver knowingly and voluntarily; no federal rule requires a different result.	Waiver valid; no AEDPA error.
Competency examination	District court should have ordered competency evaluation.	Record showed Cowans competent; no need for a competency hearing.	No reversible error; state court reasonable.
Dog-tracking videotape due process	Video evidence violated due process by inflaming the jury.	Trial court gave limiting instructions; evidence had marginal value and was properly managed.	Video did not deny due process.
Ineffective assistance of trial counsel (mitigating evidence, competency, searches, pre-trial investigations)	Counsel failed in multiple respects to pursue mitigating evidence and challenge forensic/forensic procedures.	Counsel's decisions were reasonable; defendant prevented some actions; no prejudice shown.	No Strickland prejudice; state court reasonable.
Ineffective assistance of appellate counsel	Appellate counsel should have raised five asserted issues on direct appeal.	Ohio Supreme Court independently addressed the merits of the claim; failure to raise was not prejudicial.	No prejudice; reasonable basis for denial.
