Suspect "led us to the evidence" in Montana camper's brutal killing, initially thought to have been bear attack

A suspect has been arrested nearly three weeks after a Montana camper was found brutally killed in an attack that was initially reported as a bear attack, authorities said late Wednesday.

The Gallatin County Sheriff's Office said it had identified a suspect in the murder of Dustin Kjersem, who was found dead in his tent earlier this month. The suspect, who was not identified, was in custody on unrelated charges, authorities said.

"The suspect is cooperating with our detectives and has led us to the evidence we have identified in prior press releases," the sheriff's office said.
