Report: Mark Hacking Confessed to Brothers

A Salt Lake County judge on Thursday granted an extension to file formal charges against Mark Hacking (search) in what is now believed to have been the murder of his wife Lori. The prosecution requested the extension, set to expire on Monday at 7 p.m. EDT, while police continue to search for Lori Hacking's (search) body.

Mark Hacking confessed to killing and disposing of his wife's body, the Salt Lake Tribune reported Thursday.

Hacking's brothers Scott and Lance together were the "reliable citizen witness" police said Mark confessed to about murdering his wife, Scott Hacking told the Salt Lake Tribune.

On July 24, five days after his wife's disappearance, Mark Hacking told his brothers that he killed her while she was sleeping and threw her body in a trash bin. A police affidavit released this week quoted a "reliable citizen witness" who disclosed the confession.

Scott Hacking said the information was delivered to police through an intermediary the next day.

On the following Sunday, the biggest volunteer search since the woman was reported missing was held. Some churches canceled services so members could take part. Estimates of the turnout ranged from 1,500 to 3,000.

Scott Hacking said that after learning that Mark had lied about so many things, he could not trust the statement about the disposal of the body, the Tribune reported.

The following Tuesday, the official search was called off. The families said the searchers were entering more risky terrain. They asked that people with specialized skills or equipment sign up for possible future searches.

Meanwhile, volunteers continued searching on their own, and four days later — last Saturday — the families asked that the searching end altogether. They said that Mark Hacking had provided information that made the search unnecessary.

Mark Hacking was arrested Monday as he was about to be released from the psychiatric ward where he'd been since being found naked outside a hotel the night after he reported his wife missing.

Meanwhile, FOX News has learned more about some of the evidence investigators may be examining. Sources close to the case told FOX that the University of Utah (search) psychiatric ward, where Mark Hacking had worked as an orderly, might have a surveillance video showing Mark was there the morning he said his wife disappeared.

There was a stir on Wednesday when it was learned that Hacking, when asked during his booking to disclose any aliases, gave the name "Jonathan Long." Reporters rushed to try to find out what he might have done under that name. Law enforcement authorities said they didn't know. But his attorney, Gil Athay (search), said that simply was the hospital-assigned code name under which Hacking was admitted, used to protect his identity.

Hospital officials, citing privacy laws, have refused to even acknowledge he was there and would not confirm Athay's statement.

A judge set Hacking's bail at $500,000, but Athay said he and his client have not even discussed the possibility of posting bail, the Tribune said.

Meanwhile, police and cadaver dogs returned on Thursday to the county landfill to search for the body of Lori Hacking.

They have 3,000 tons of trash to search through. The digging started within days after Mark Hacking reported his wife missing and has been continuing on and off since then. The searches were halted when the dogs were needed on other assignments and when their handlers felt the animals needed time off.

Large spotlights lighted the area Wednesday night and a backhoe tore out large chunks of garbage that were then spread out for the dogs to go over.

Mark Hacking called police July 19 and said his wife had failed to show up for work after going for an early morning jog.

Police believe that three days before she vanished, Lori Hacking discovered that her husband had not been enrolled in a North Carolina medical school where the couple was packing to move. It also was discovered that he had lied about graduating from the University of Utah.

Police arrested Hacking on Monday on evidence including a bloody knife found in his bedroom, a discarded mattress and a reported psychiatric ward confession.

Thursday was the deadline for Salt Lake County District Attorney David Yocom to file charges, but he said he might not be ready and might ask the court for an extension.

Yocom declined to say whether he would seek the death penalty, but did say the wishes of the victim's family are given great weight in such decisions.

Lori Hacking's brother Paul Soares, asked about the appropriate penalty during a televised interview Wednesday night, said, "I try not to think about that. I trust the people of the state of the Utah to come up with right judgment."

Scott Hacking said he was aware his brother, if convicted, could face a possible death penalty.

"I certainly worried about that," he told the Tribune. "My family believes in the justice system .... If those consequences are the ones he has to face, then again, we will support him through that point, though I hope he does not have to face that consequence."
