Drew Peterson Arrested in the Murder of Third Wife Kathleen Savio

BOLINGBROOK – Authorities arrested Drew Peterson Thursday near his Bolingbrook home for the murder of his third wife Kathleen Savio, according to police sources. 

Police took Peterson into custody at Weber and Lilly Cache roads.  Savio, 40, was found dead in a dry bathtub in her Bolingbrook home in March 2004.

At the time, Illinois State Police failed to find anything suspicious and her death was ruled an accidental drowning by a coroner’s jury.

After Peterson’s fourth wife, Stacy, then 23, disappeared in October 2007, officials reclassified Savio’s death as a homicide and gave the state police another opportunity to figure out who did her in.

Savio’s body was exhumed from its grave. An autopsy conducted in November 2007 determined Savio was the victim of a homicide.

Peterson wasn’t named a suspect in Savio’s death, but state police determined Stacy's disappearance is a "potential homicide" and say Peterson is a suspect in the case.
