JOLIET, Ill. (AP) — The lead investigator in the death of Drew Peterson's third wife says he never considered it was anything but an accident.
Retired Illinois State Police Sgt. Patrick Collins testified at a Friday hearing meant to determine what, if any, "hearsay" evidence prosecutors can use during Peterson's murder trial.
The former Bolingbrook police officer has pleaded not guilty in Kathleen Savio's death.
Her body was found in her home bathtub in 2004. Her death was ruled a homicide only after Peterson's fourth wife, Stacy Peterson, disappeared in 2007.
Collins says he didn't even collect evidence from Savio's home. He stopped short of admitting he was wrong to believe her death was accidental. But he concedes his investigation could have been more thorough.
