State v. Harmon, 2020 Ohio 590

Background

Harmon was indicted for attempted murder, felonious assault, and kidnapping (each with a repeat violent offender specification) arising from a June 23, 2017 stabbing of Lavandon Smith in Harmon's apartment; a jury convicted Harmon and the trial court imposed a total 16-year sentence.
Dispute began over a $400 loan/transaction; Smith went to Harmon's apartment to collect repayment; Harmon stabbed Smith multiple times (shoulder, hands, abdomen, chest); Smith required major surgery.
Smith had a concealed-carry permit but testified he was not carrying his gun that day; Harmon testified he believed Smith reached for a gun and stabbed in self-defense with a small knife kept in his sweatshirt pocket.
Evidence included Smith's testimony about being blocked from exiting (Harmon allegedly put his body against the door and grabbed Smith's arm), Smith’s left sandal found inside the apartment, and a box cutter found in Harmon’s apartment.
During trial Smith twice referenced Harmon’s prior imprisonment; those answers were objected to and struck and the court instructed the jury to disregard them; Harmon later testified about his own prior convictions.
Harmon raised four assignments of error on appeal: (1) trial court plain error for not declaring a mistrial over prior-record references; (2) ineffective assistance for counsel not moving for mistrial/requesting curative instruction; (3) insufficiency of evidence (kidnapping); (4) manifest-weight challenge (self-defense). The court affirmed.

Issues

Issue	Plaintiff's Argument (State)	Defendant's Argument (Harmon)	Held
1) Did the trial court commit plain error by not sua sponte granting a mistrial after witness references to Harmon’s criminal record?	References were isolated, immediately objected to and struck, and curative instructions were given — no plain error.	The references prejudiced the jury, effectively forced Harmon to testify, and warranted a mistrial.	No plain error: brief references cured by objection/strike and curative instruction; jury presumed to follow instruction.
2) Was counsel ineffective for failing to move for mistrial or request additional curative instructions?	Counsel’s conduct was reasonable trial strategy; curative instruction already given; a mistrial motion would have been futile.	Counsel performed deficiently by not seeking a mistrial or a stronger limiting instruction.	No ineffective assistance: counsel’s choices within reasonable professional judgment; any motion would likely be futile and no prejudice shown.
3) Was there insufficient evidence to support the kidnapping conviction?	Evidence (Harmon blocking door, grabbing Smith’s arm, Smith’s sandal inside apartment) supports restraint by force to inflict harm — sufficient.	Smith may have locked the door himself; inability to leave resulted from his own action, not defendant’s restraint.	Evidence sufficient: viewed in prosecution’s favor a rational trier could find kidnapping elements proved beyond a reasonable doubt.
4) Was the verdict against the manifest weight of the evidence because Harmon acted in self-defense?	Jury reasonably disbelieved Harmon’s claim—no gun was seen; multiple witnesses saw no weapon; Harmon admitted he did not actually see a gun.	Harmon proved self-defense by preponderance: he was not at fault, reasonably believed he faced imminent danger, and had no duty to retreat in his home.	Not against manifest weight: jury credited State’s witnesses and Harmon’s credibility was for the jury to resolve; self-defense not proven by preponderance.
