Utah authorities say they suspect foul play may be involved in the disappearance of a 28-year-old mother.
West Valley City Asst. Police Chief Craig Black says Susan Powell's disappearance is so out of character that it's now a criminal investigation.
Powell was reported missing Dec. 7 when she didn't show up to work and her two children were not dropped off at day care.
Her husband, Josh Powell, says he went camping with their boys, ages 2 and 4, in subfreezing temperatures about 12:30 a.m. that day and returned in the evening.
Black says Josh Powell has been uncooperative in providing any details that might explain what happened to his wife. Black says Josh Powell also hasn't specified where he went camping.
He has not been named a suspect.
