Coroner: Could be weeks until doctor rules on ex-wife's death

The Will County coroner says it could be several weeks until an independent doctor gives authorities his opinion on the manner of death of the ex-wife of a suburban Chicago police officer.

Officials exhumed Kathleen Savio's casket Tuesday from a plot at the Queen of Heaven Catholic Cemetery west of Chicago.

Coroner Patrick O'Neil says Doctor Larry Blum has conducted more than 9,000 autopsies. He says Blum will offer an independent opinion on the manner of Savio's death, which a coroner's jury originally ruled as accidental.

Savio was married to Bolingbrook Police Sergeant Drew Peterson. She was found dead in her bathtub in 2004. Investigators reopened Savio's case after Peterson's current wife, Stacy, disappeared last month.
