State v. Diar

Summary

The Ohio Supreme Court reviews Nicole Diar’s convictions for the aggravated murder of her four-year-old son and related offenses arising from a fatal house fire. The court affirms the convictions but reverses the death sentence and remands for a new mitigation hearing. The opinion addresses, among other issues, the admission of character and other-acts evidence.

Holdings

1. Evidence of other crimes, wrongs, or acts may be admitted for a noncharacter purpose such as motive, intent, opportunity, plan, knowledge, identity, or absence of mistake or accident; the challenged evidence concerning Diar's treatment of Jacob, use of babysitters, codeine instructions, and conduct after Jacob's death was either properly admitted for those purposes or, when improperly admitted, was not prejudicial.
2. The trial court did not abuse its discretion by denying severance because the codeine-related offenses were sufficiently connected to the murder charges, the evidence was admissible as other-acts evidence, and the evidence supporting the joined offenses was simple and direct.
3. The evidence was legally sufficient to support the aggravated-murder convictions even though the coroner could not determine the precise mechanism of death.
4. The reasonable-doubt, guilt-or-innocence, purpose, and verdict-form instructions, considered in the context of the entire charge, did not violate due process or shift the State's burden of proof.
5. Although the prosecutor committed misconduct in several instances, including repeated leading questions after objections had been sustained, the misconduct did not permeate the trial or prejudice Diar's substantial rights and therefore did not warrant reversal.
6. Counsel's failure to request a continuance after receiving potentially impeaching money orders was deficient performance, but Diar failed to establish prejudice; her remaining ineffective-assistance claims also failed.
7. The trial court erred by failing to instruct the capital-case jury that a solitary juror could prevent a death-penalty recommendation by finding that the aggravating circumstance did not outweigh the mitigating factors beyond a reasonable doubt.

Questions Presented

1. Whether the trial court improperly admitted character and other-acts evidence under Evid.R. 404(B), including evidence concerning Diar's parenting, use of babysitters, giving Jacob codeine, and her conduct after Jacob's death.
2. Whether the trial court abused its discretion by refusing to sever the complicity-to-corrupt-another-with-drugs counts from the murder and related charges.
3. Whether gruesome crime-scene and autopsy photographs were improperly admitted.
4. Whether the evidence was legally sufficient to support the aggravated-murder convictions despite the coroner's inability to identify the exact cause of death.
5. Whether the guilt-phase jury instructions and verdict forms improperly diminished the reasonable-doubt standard or shifted the burden of proof.
6. Whether prosecutorial misconduct and ineffective assistance of counsel deprived Diar of a fair trial.
7. Whether the penalty-phase instructions were erroneous because they did not inform the jury that a solitary juror could prevent a death-penalty recommendation.
