CHICAGO (AP) - Illinois State Police say former police officer Drew Peterson remains a prime suspect in his wife's disappearance. Sergeant Thomas Burek says investigators have new information that only reinforces that the suburban Chicago man is a suspect in Stacy Peterson's disappearance. The state police spokesman didn't provide details. The comments come as relatives prepared to mark Stacy Peterson's 24th birthday today. She went missing in October. The comments also come after Drew Peterson's attorney said a racy message sent to Stacy Peterson's cell phone in September supports the claim she left her husband for another man. But in his Friday statements, Burek said it's clear she didn't voluntarily end all contact with her children, family and friends.
