Reputed mobsters Anthony (Little Tony) Spilotro and his brother, Michael Spilotro, were reported missing, police said. Anthony, 48, and Michael, 41, were last seen Saturday in the Chicago suburb of Oak Park, Detective Ronald Ballarini said. Federal and Las Vegas police have contended for years that Anthony Spilotro has been the overseer of organized crime in Las Vegas. A trial on charges of racketeering ended in a mistrial earlier this year. Spilotro was awaiting trial on charges of skimming money from Las Vegas casinos.
