State v. Willey

2026-Ohio-242 · Court of Appeals of Ohio, Fourth Appellate District · January 23, 2026 · No. Ross App. No. 25CA1; Case No. 25CA1

Summary

The Fourth District Court of Appeals of Ohio affirmed Matthew D. Willey's conviction for involuntary manslaughter arising from the fatal assault of a fellow inmate. The court held that the State disproved Willey's defense-of-another claim because the person he assisted was at fault in creating the affray and Willey used force exceeding that necessary for defense. The court also upheld the conviction against sufficiency and manifest-weight challenges and found no reversible plain error in the jury instructions.

Writing for the Court
Michael D. Hess; Abele, J.; Wilkin, J.
Jurisdiction
Ohio Court of Appeals, Fourth Appellate District, Ross County
Decision date
January 23, 2026
Docket number
Ross App. No. 25CA1; Case No. 25CA1
Procedural posture
Willey appealed his jury-trial conviction for first-degree-felony involuntary manslaughter, challenging the sufficiency and manifest weight of the evidence and the trial court's jury instructions concerning defense of another, deadly and nondeadly force, and retreat.
Standard of review
Sufficiency of the evidence is reviewed by asking whether, viewing the evidence most favorably to the prosecution, any rational trier of fact could have found the essential elements beyond a reasonable doubt. Manifest-weight review requires review of the entire record, weighing evidence and reasonable inferences, considering witness credibility, and determining whether the jury clearly lost its way and created a manifest miscarriage of justice. Unpreserved jury-instruction claims are reviewed for plain error, and invited instructional error is not reviewable when the defendant affirmatively approved the instruction.

Questions Presented

  1. Whether Willey's involuntary-manslaughter conviction was against the manifest weight of the evidence because the State failed to disprove that he acted in defense of another.
  2. Whether the trial court plainly erred in instructing the jury on deadly and nondeadly force in defense of another and on a duty to retreat.
  3. Whether sufficient evidence established that Willey's conduct was the proximate cause of Keeton's death.
  4. Whether Willey's conviction was against the manifest weight of the evidence because the State failed to establish proximate causation.

Holdings

  1. The conviction was not against the manifest weight of the evidence because the State presented substantial evidence that Robbins was at fault in creating the situation giving rise to the affray and that Willey used force exceeding what was necessary, becoming the aggressor.
  2. Willey could not obtain relief based on the deadly- and nondeadly-force instructions because he affirmatively approved the instructions, thereby inviting any error.
  3. The retreat instruction did not warrant reversal because the instruction correctly stated that retreat could not be considered in evaluating the necessity of nondeadly force and that Robbins had no duty to retreat from a place where he had a lawful right to be; in any event, Willey failed to establish plain error or prejudice.
  4. Sufficient evidence supported the finding that Willey's conduct was a proximate cause of Keeton's death, and the conviction was not against the manifest weight of the evidence.

Key quotations

Taken together, these two principles mean that a homicide defendant's conduct ordinarily must be “the but-for cause of” the person's death. (¶49)
Thus, regardless of which form of trauma may have caused Keeton’s spleen to rupture, the evidence was that Willey had inflicted both forms. (¶57)

Factual background

While incarcerated at the Chillicothe Correctional Institution, Michael Keeton was summoned by Willey to a restroom where inmate Charles Robbins was waiting. Evidence indicated that Robbins had demanded that Keeton cover a tattoo and that Willey, Robbins, and another inmate had planned an attack. Robbins testified that Willey repeatedly struck Keeton until Keeton collapsed unconscious and convulsing in a pool of blood; Keeton later died from exsanguination caused by blunt-force trauma and a ruptured spleen. Prison video, photographs, witness testimony, and an autopsy supported the conclusion that Willey's assault, or the fall caused by it, caused the fatal injuries.

Procedural history

A Ross County grand jury indicted Willey for involuntary manslaughter under R.C. 2903.04. After a jury found him guilty, the Ross County Court of Common Pleas denied his Crim.R. 29 acquittal and Crim.R. 33 new-trial motions and sentenced him to an indefinite minimum eight-year and maximum twelve-year prison term, with restitution. The Fourth District affirmed.
