A bloodstained knife with strands of hair attached is among the evidence Salt Lake police seized from the apartment of Mark and Lori Hacking, sources told the Deseret Morning News Saturday.

The knife is among numerous items taken — including a set of box springs, some bedding and computers — from the couple's home in the six days since the newly pregnant Lori Hacking reportedly went missing while taking a sunrise jog Monday in Memory Grove.

The knife may or may not be a key piece of evidence for Salt Lake police trying to solve the mystery of Lori Hacking's disappearance. But police weren't confirming, denying or even talking about the evidence on Saturday.

"We're not going to talk about anything of evidentiary value," police detective Dwayne Baird said.

After learning about the knife late Saturday, Mark Hacking's brother, Lance Hacking, had this to say:

"You know, we have confidence in law enforcement and their ability to handle the investigation. In the meantime, we're gonna continue to focus on the search for Lori."

Despite days of searching by hundreds of volunteers, Lori Hacking, 27, has yet to be found. Mark, her husband of five years, has spent much of the past week under the care of doctors in a psychiatric unit at the University of Utah Medical Center.

Also on Saturday, a clump of dark hair was retrieved by evidence technicians from a Dumpster at a Chevron gas station at 2100 S. 300 West. A station attendant reported the finding to police, Salt Lake police detective Phil Eslinger said.

It too will be added to the growing cache of evidence being evaluated, and it may not necessarily be connected to the case, he added.

"We're looking into everything," Eslinger said.

The gas station is less than two blocks from Bradley's Sleep Etc., 2255 S. 300 West, where Mark Hacking bought a new mattress Monday, just 26 minutes before reporting Lori's disappearance to police.

In other developments Saturday, cable's Fox News reported that police sources told the television network they had found bloodstains in the Hacking's apartment. That information blind-sided family members and police.

Baird said he did not know if those reports were "accurate or inaccurate."

"I'm not at liberty to discuss what it is as far as the investigative aspect goes," he said. "We have procedures that we deal with, and if it's evidentiary in nature, we're not going to discuss that. And certainly if it has to do with testing, that you're naming the results of that testing, we don't have it."

A plea for help

Earlier in the day, as Utah families and visitors gathered on Salt Lake City's Main Street for an enjoyable morning of watching the parade, Lori Hacking's parents continued to plead for help in finding their missing daughter.
