With some leads dead-ending, investigators are sharing new details about the slaying of Kay Mortensen.

Utah County sheriff's deputies have released a list of 32 guns that were found missing from Mortensen's home after his throat was cut Nov. 16 in his Payson home.

Investigators previously were mum on the missing guns. Detectives had received tips of stolen weapons that may have belonged to Mortensen, who left behind a detailed written inventory of his gun collection.

"We didn't want to [risk] those guns being moved across the state or disappearing," Utah County sheriff's Sgt. Mike Brower said.

Those tips -- Brower wouldn't say how many -- did not lead to guns that belonged to Mortensen but resulted in unrelated weapons charges in the counties where they were found.

Investigators released names and serial numbers of Mortensen's missing weapons this week because "those leads were exhausted," Brower said.

Now investigators have turned to the public for help finding the 32 guns, valued at $26,000, Brower said.

The weapons range from SKS rifles worth about $150 to a large, belt-fed Browning machine gun valued at about $2,000, according to firearms instructor Clark Aposhian.

Also of collectors' note is a Herters 243 U-9 rifle, Aposhian said. The value of the gun is not certain, he said.

Because Mortensen's list does not specify whether some guns are semiautomatic or fully automatic, the value of the collection is not certain. Fully automatic guns are worth tens of thousands of dollars, Aposhian said.

It is not clear when the 32 guns were taken, Brower said. Some could have been taken during the murder, and some might have been taken as long as two years ago, when Mortensen served a mission in Cove Fort.

Brower denied that the gun inventory was released because investigators were running out of leads.

"This is just one other lead we're following up on," he said. "There are still persons of interest, and we're still pursuing other leads."

In January, deputies named Mortensen's son and daughter-in-law, Roger and Pam Mortensen, as persons of interest, claiming the couple made inconsistent statements.

The couple have claimed they were held hostage by two men and tied up at Mortensen's home during the slaying.

Since being named as persons of interest, the two have declined police interviews, Brower said.

The couple's lawyer, Greg Skordas, could not be reached Thursday for comment.
