State v. Geiger, 2020 Ohio 2679

Appellant Zachary Geiger was indicted for felonious assault after an inmate, Walter Shannon, was attacked in the Lebanon Correctional Institution dayroom on Nov. 24, 2018; attackers used fan motor parts wrapped in a sock and Shannon suffered a laceration and a fractured jaw requiring surgery.
Video and corrections-officer testimony placed Geiger and his cellmate, Cody Mills, in the dayroom; officers observed the assault and recovered the improvised weapon after Mills slid it toward Geiger as they were subdued.
In a recorded post-incident interview (after Miranda waiver), Geiger told Sgt. Madden he and Mills planned the attack to try to get transferred, admitted punching Shannon (initial blow and possible additional strikes), and denied knowing about the weapon until later.
Mills testified at trial that he pled guilty, retrieved and used the weapon, and that Geiger assisted in the assault (Mills claimed Geiger kicked but did not punch and did not know about the weapon).
The jury convicted Geiger of complicity to felonious assault; the trial court sentenced him to three years, consecutive to his existing term. Geiger appealed, arguing insufficiency and that the verdict was against the manifest weight because he lacked knowledge of the weapon and thus the requisite culpability.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Sufficiency of the evidence to support complicity/ felonious assault conviction	State: Video, officer observations, Geiger's admission of planning and striking Shannon, and conduct during attack show he aided/abetted and acted knowingly	Geiger: No evidence he knew Mills would use a weapon; at most association and limited force, so no knowing cause of serious harm	Court: Evidence sufficient — planning, admissions, assaultive conduct, and weapon taken from shared cell support conviction
Manifest weight of the evidence (credibility and intent)	State: Jury could disbelieve denials; brutality and continuation of attack made serious harm foreseeable; conduct supports shared criminal intent	Geiger: Testimony shows he did not know of the weapon and did not inflict the weapon-caused injuries	Court: Verdict not against manifest weight — jury entitled to credit prosecution evidence and inferences of shared intent; conviction affirmed
