COLUMBUS, Ohio (AP) – An Ohio county coroner says a special examination will look for signs of traumatic brain injury in an Ohio State athlete found dead of an apparent self-inflicted gunshot wound.

Dr. Anahi Ortiz of Franklin County says the examination by an Ohio State neuropathologist is being done because Kosta Karageorge had a reported history of multiple concussions.

Ortiz said Monday that an autopsy determined the 22-year-old Karageorge died of a gunshot wound, but she hasn't yet definitively ruled it a suicide.

Columbus police said Sunday that Karageorge died of an apparent self-inflicted gunshot wound.

His mother, Susan Karageorge, told police in a missing-person's report that her son had had several concussions.

Karageorge was a wrestler for three years and joined the football team as a walk-on this season.
