(CNN) -- A missing Ohio State University football player has been found dead, authorities said Sunday. Kosta Karageorge, a fifth-year senior, had missed practice Wednesday and hadn't been seen since. Sgt. Richard Weiner, with Columbus police, said that Karageorge died from what appears to be a self-inflicted gunshot wound. His body was found inside a Dumpster and identified at the scene through tattoos, Weiner said. A handgun was also recovered at the scene. It was not immediately clear how long the body had been in the Dumpster, Weiner said. An investigation is ongoing.
