State v. Dean, 2019 Ohio 1391

Defendant Da’Jon Dean was indicted on felonious assault, assault, and aggravated riot stemming from a barroom brawl captured on surveillance video.
Victim testified he intervened to help a friend being attacked and was struck in the head with a billiard ball, suffering a concussion and a chipped skull; photos showed a large welt.
Surveillance footage showed Dean picking up and throwing a billiard ball that struck the victim and ricocheted across the room.
Dean waived a jury and was tried before the bench; the court convicted him of felonious assault and aggravated riot, acquitting him of simple assault.
Defense moved for acquittal on felonious assault arguing a billiard ball is not a "deadly weapon;" the court denied the motion.
On appeal, Dean challenged sufficiency/manifest weight of the evidence and argued trial counsel was ineffective for not asserting the defense-of-others affirmative defense.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Sufficiency that object was a "deadly weapon" for felonious assault	State: manner of use (thrown at head, caused serious injury) permits inference it was deadly	Dean: billiard ball is not a deadly weapon	Held: Sufficient evidence; manner of use allowed inference it was a deadly weapon; conviction upheld
Manifest weight of evidence	State: testimony, photos, and surveillance supported conviction	Dean: argues court lost way because no deadly weapon shown	Held: No manifest miscarriage; weight supports conviction
Failure to plead that Dean knowingly caused harm	State: evidence showed intentional throw; implied in video/testimony	Dean: asserts State failed to show he knowingly caused harm (undeveloped)	Held: Argument not developed; court declined to address it
Ineffective assistance for not asserting defense of others	State: counsel not deficient; record lacks showing others were justified in using force	Dean: counsel should have claimed he acted to protect friends	Held: No ineffective assistance; Dean failed to show defense-of-others elements or prejudice
