The thieves left behind several computers and a television, all in the same rooms as the guns.

Dunn said he lost more than just a gun collection, since nine of them had belonged to his late grandfather.

“Eighty-six hundred dollars, that’s nothing to me," he said of value of his share of the guns. "That’s not what I lost. If I could just get one back it would give me some type of hope.”

Looper’s mother, Judy Thompson, felt the same. The burglar took her mother’s gold bracelet, more than 100 years old, which contained a photo of Thompson and her sister as babies. A new watch still in the box was also apparently taken.

“You know you just feel, I mean after it set in, you’re angry,” Looper said. “You get mad. Because it’s like, someone came into my house and was in my stuff and they took things that are important to us. It just upset me.”

Billings Police officials say they have a suspect, but declined to comment further about the theft.

Billings saw another major gun theft in 2010 when two men broke into a trucking and storage facility, stole 136 guns and drove them to California where they swapped them for money and drugs, according to court documents. It is believed to be the biggest gun heist in state history.
