WEST VALLEY CITY, Utah (AP) -- A police agency is offering new details about the disappearance of Susan Powell, a Utah mother whose now-dead husband was a prime suspect.

West Valley City police were set to offer "detailed updates" on an investigation that's been kept under wraps since Powell vanished in 2009. The news conference was set for 3 p.m. MDT Monday.

Deputy Police Chief Mike Powell - no relation - declined to elaborate ahead of the press briefing.

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.
