"SALT LAKE CITY — Authorities have upgraded their investigation into the disappearance of a Utah mother to a criminal probe and say her husband's "lack of cooperation" has made them increasingly suspicious of him.
Susan Powell, a 28-year-old mother of two young children, was reported missing Dec. 7, when she didn't show up for work. She was last seen a day earlier.Josh Powell said he went camping with their boys, ages 2 and 4, in subfreezing temperatures about 12:30 a.m. on Dec. 7 and returned in the evening.
"Every lead we've been offered so far would leave us to believe this is out of character (for Susan) and thus suspect foul play is involved," West Valley City Asst. Police Chief Craig Black said Wednesday.
He said that her husband, Josh Powell, has not been named a suspect but investigators are highly interested in him.
"Josh's unusual lack of cooperation for a husband looking for his wife with the police department, you know, it certainly causes us to ask questions as to why would he do things to exclude the resources that we can bring to the table to find Susan," Black said.
But Josh Powell has been uncooperative in providing any details that might explain what happened to his wife, Black said.
Among other things, Josh Powell hasn't specified where he went camping or where he was all day on Dec. 7, he said.
