A 35-year-old man camping in a remote Montana forest was found killed in his tent following a vicious attack initially suspected of being a bear mauling, authorities said. Victim Dustin Kjersem went camping northeast of Big Sky, Montana, on Oct. 10 with plans to meet a friend the next day, Gallatin County Sheriff Dan Springer said.

Dustin Kjersem’s body was discovered by a friend at a remote Montana campsite. The 35-year-old’s injuries were so severe that it looked like a bear attack.
