When Dustin Kjersem’s girlfriend found his body at a campsite in the Montana woods, she suspected Kjersem had been killed by a bear, because of the severity his wounds. But police say a man did it — and that they’ve now arrested a suspect who has admitted to the crime.

The accused killer “removed items from the campsite he believed had evidence that could tie him to the crime,” including an axe used against Kjersem, Gallatin County Sheriff Dan Springer said in a news briefing on Thursday.
