Drew Peterson’s sons subpoenaed by grand jury

Former Bolingbrook police Sgt. Drew Peterson’s two sons, whom he had with his third wife, Kathleen Savio, were subpoenaed Wednesday by a grand jury. The sons are Christopher, 13, and Tom, 15.

An independent pathologist for Will County last week ruled Savio’s death a homicide.

Peterson has been named a suspect in the disappearance of his fourth wife, Stacy Peterson. He has denied any involvement with her disappearance.
