A friend testified Wednesday that Kathleen Savio was so afraid of her ex-husband Drew Peterson she put a deadbolt on her bedroom door.Peterson is the former Bolingbrook police officer charged with killing Savio.

At a pre-trial hearing, Kristin Anderson said that Savio also kept a kitchen knife under her mattress. Anderson and her family lived in Savio's house for a couple of months in 2003.

Anderson also testified about an incident in which Peterson reportedly put a knife to Savio's throat and threatened to kill her.

Anderson said she contacted Illinois State Police after Savio's death but they never responded.

The pre-trial hearing will determine what hearsay evidence can be used in Peterson's murder trial.
