A police agency is closing the active investigation of the disappearance of Susan Powell, a Utah mother whose now-dead husband was a prime suspect, citing a lack of leads.

West Valley City police are also releasing the case file, with details that have been kept under wraps since Powell vanished in 2009.

Police held a news conference Monday afternoon.

Police spent two days unsuccessfully searching in rural Oregon last week for any trace of Powell. West Valley City Manager Wayne Pyle told The Associated Press that police were at the end of the investigation, without any active leads, and might close the case.

Police have said they would reopen the case if they get new information.
