BOLINGBROOK, Ill. (AP) - As authorities in Illinois investigate the disappearance of a police officer's wife, her family is holding out hope that she'll be found safe.
Stacy Peterson vanished Sunday. State police have sent divers to search a pond near the couple's house in the Chicago suburb of Bolingbrook. Investigators are also searching two vehicles.
Authorities say Drew Peterson is cooperating and that they've found no evidence of wrongdoing. He's a sergeant in the Bolingbrook police department.
Peterson has said his wife called him Sunday night to tell him she was leaving. He thinks it was for another man.
But the wife's family says she would have never left her two children behind. They also say Peterson was afraid of her husband and wanted to divorce him.
Meanwhile, authorities have started reviewing files on the death of Sergeant Peterson's ex-wife. She was found dead in her bathtub in 2004.
