Brad Renfro, the troubled young actor whose film career dissolved as he struggled with drug and alcohol problems, has died. He was 25. His body was found in his Los Angeles home early Tuesday, his lawyer Richard Kaplan said. The cause of death was not immediately known. Renfro served 10 days in jail in May 2006 after pleading no contest to driving while intoxicated and pleading guilty to attempted possession of heroin.
