An autopsy on the exhumed body of Drew Peterson's third wife found her death was not an accident. Kathleen Savio died by drowning and her death was ruled a homicide, Dr. Larry W. Blum said in an autopsy report released by the state's attorney's office. It was the second autopsy performed on Savio. She was found dead in her bathtub in March 2004, shortly before her divorce with Peterson was finalized. Four years ago, a coroner's jury ruled her death was an accident. Peterson told a newspaper the new ruling in Savio's death shocked him.
