A 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 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.
