It was reported that between 2002 and 2004, police were called out to the Peterson house 18 times on domestic disturbance calls, including calls for returning children late after visitation, during Drew Peterson 's third marriage, to Kathleen Savio (June 13, 1963 - March 1, 2004). Kathleen Savio's body was subsequently found in a circular bathtub on March 1, 2004. Her death was initially ruled an accidental drowning.
However, following Stacy Peterson 's disappearance, Savio's body was exhumed and underwent forensic examination on November 16, 2007. Dr. Michael Baden, a former New York City chief medical examiner who conducted the examination at the request of Savio's relatives and Fox News, concluded that she died of drowning following a struggle when her body was placed in the bathtub.
