Columbus, OH (SportsNetwork.com) - The body of missing Ohio State football player Kosta Karageorge was found Sunday near campus, police said.

The Columbus police department said Karageorge, who was reported missing on Wednesday, was found in a dumpster not far from his apartment where he was last seen.

Police said the preliminary investigation shows the walk-on senior defensive lineman died from what appears to be a self-inflicted gunshot wound.

A gun was recovered at the scene, police said.

Karageorge, who was 22, missed practice after disappearing and had not been seen since leaving his apartment in dark clothing at 2 a.m. on Wednesday.

His sister told The Columbus Dispatch that his roommates said he was leaving to take a walk.

"He had some extenuating circumstances that night that lead us to believe he was upset," Sophia Karageorge told the paper.

She said her brother, a former wrestler, had a history of sport-related concussions and that the family was "very concerned that he's not himself and that he maybe doesn't know what's going on."
