Bathtub drowning wasn't suspicious

CHICAGO, Aug. 18 (UPI) -- A coroner's report shows Illinois state police were not suspicious about the bathtub drowning in 2004 of a healthy, 40-year-old suburban Chicago woman.

A copy of the report by the Will County deputy coroner suggesting the death of Kathleen Savio was an accident has been obtained by The Chicago Tribune, the newspaper reported Monday.

Savio was the third wife of former Bolingbrook police Sgt. Drew Peterson whose fourth wife, Stacey Peterson, has been missing since last October.

Investigators and experts re-examining Savio's death as a possible murder are questioning how state police could have been so quick to overlook signs that something sinister may have happened to Peterson's third wife, the Tribune says.

State police Lt. Scott Compton has declined to comment on why his agency's technicians and investigators concluded the death was not suspicious.

Peterson, 54, has not been named a suspect in Savio's death.
