The body of an Ohio State University football player who had gone missing was found in Columbus, Ohio on Sunday, according to authorities.

Kosta Karageorge, a 22-year-old OSU defensive lineman and wrestler, disappeared Wednesday, and his body was found five days later. Karageorge apparently commited suicide inside of a dumpster near his apartment, by way of a self-inflicted gunshot wound.

Investigators were able to identify the body via various tattoos, according to Sgt. Rich Weiner, a Columbus police spokesman.

A woman told reporters that her son had found the body, and police revealed that the handgun was likewise found in the dumpster, though they are not sure it belonged to Karageorge.

Susan Karageorge, the deceased’s mother, had previously commented that her son suffered concussions, and that he had sent her a text shortly before he went missing. The text was an apology for being an “embarrassment,” as a result of his injuries.

The Centers for Disease Control and Prevention reports that all football-related concussions are serious, most occur without loss of consciousness and recognition and proper response to concussions when they first occur can help prevent further injury or even death.

The CDC adds that symptoms of a concussion can include one pupil larger than the other, weakness, numbness, decreased coordination, slurred speech, convulsions, unusual behavior, confusion, restlessness and agitation.

OSU said in a statement, “The Ohio State University Department of Athletics was shocked and saddened to learn today of the death of student-athlete Kosta Karageorge, a senior from Columbus. Our thoughts and prayers are with the Karageorge family, and those who knew him, during this most difficult time.”
