First day of Peterson trial ends

Drew Peterson's murder trial began Tuesday.

The former Bolingbrook police officer is charged with killing his third wife, Kathleen Savio. She was found dead in her home in 2004. She was discovered in a bathtub that didn't have any water in it. Her death was originally ruled accidental. But, her body was exhumed in 2007, and then her death was ruled a homicide.

Prosecutors will rely almost entirely on hearsay statements made by Savio before her death, while the defense will point out the absence of any physical evidence.

The defense claims Savio was bitter about Drew's affair with Stacy Peterson, and that she made up stories to help her divorce deal. The prosecution says Peterson didn’t want to share his $300,000 pension with her.

It's not clear whether Peterson will testify in his own defense.

“The way they always do a murder case, they’ll present someone who was one of the last people or the last person to see her living, then they’ll present someone to say that they found her she was dead, they’ll sort of logically go there. I suspect they’ll call the neighbors, and move on from there,” said Steve Greenberg, one of Peterson's attorneys.

Stacy Peterson vanished in 2007. Drew is a suspect in her disappearance, but hasn't been charged.
