With Peterson's current wife disappearing last week, Will County authorities revisited the 2004 death of Kathleen Savio and now suspect her death may not have actually been the result of an accident, the Chicago Tribune said Saturday.
"There are strong indications that it was a homicide," Will County State's Attorney James Glasgow said Friday. "That's why we're doing the exhumation, because there are tests that need to be done that weren't done during the first autopsy. Clearly, there are indications from the crime-scene photographs that are not consistent with an accident."
Savio was found dead in a dry bathtub in her home March 1, 2004, the apparent victim of an accidental drowning.
But with police naming Peterson as a suspect in the disappearance of his fourth wife, Stacy Peterson, both cases are now being looked at as possible homicides.
The Tribune said Peterson has maintained his innocence in both cases, saying his 23-year-old wife said she was leaving him before she disappeared.
