SALT LAKE CITY - Police arrested Mark Hacking on Monday, August 2, on suspicion of aggravated murder in the disappearance of his wife.
Lori Hacking's body has not been found. Relatives of Mark Hacking, who was arrested about 11:45 a.m. on suspicion of aggravated murder, had given police a new lead on his wife's whereabouts over the weekend that had investigators planning to resume their search at the landfill this week.
Lori Hacking, 27, has been missing since July 19, when her husband told authorities that she failed to return from an early morning jog.
'We believe that Mark Hacking is responsible for her disappearance and her death,' Police Chief Rick Dinse said.
The day after Mark Hacking, 28, reported his wife missing, he was taken to a psychiatric ward after he was seen running around at night naked in sandals outside a motel where he'd taken a room.
Investigators focused on Hacking after learning he was at a store buying a new mattress just before reporting his wife missing. Authorities were later seen removing a box spring from the couple's apartment. Investigators have refused to confirm reports that they found a mattress in a nearby trash bin.
