(Newser) – Officials in a Chicago suburb ruled today that the third wife of former policeman Drew Peterson—who's under suspicion in the disappearance of his fourth spouse—was murdered, the Chicago Tribune reports. Kathleen Savio was found dead in a dry bathtub in 2004, and her death had been considered an accidental drowning.

Authorities reopened the Savio case in November as police were investigating the disappearance of Stacy Peterson, who remains missing. Drew Peterson has not been charged in either case; he maintains his innocence, saying Stacy, 24, has run off with another man. His attorney recently said she had been seen in Peoria, though that claim was proved false.
