The search continues for a missing Salt Lake City woman. The volunteer search for Lori Hacking has been called off as authorities begin looking in more rugged terrain. Early this morning, officers using cadaver dogs searched a municipal landfill for clues. A family spokesman says the volunteer search could be resumed with specialized teams or if police receive a specific tip. In addition, all-terrain vehicles and helicopters could also be used. Police say Hacking's husband Mark is free to leave the psychological hospital where he's been since police found him running around naked at a hotel near the couple's home. He reported the woman missing and is considered a person of interest in the investigation.
