Sage was found dead in his apartment, according to the New York Post. Police had gone to check on Sage after friends were unable to get in touch with him. "There is no suspicion of foul play or criminal activity," a rep for the Los Angeles Police Department told the newspaper. It is unclear whether the death was a suicide or accidental, but the Post reports that pills were found in his home. The LAPD told TVGuide.com that the case had been turned over to the coroner.
