Gallatin County Sheriff's Office Investigates Homicide Near Big Sky

The Gallatin County Sheriff’s Office is investigating a homicide that occurred along Moose Creek Road, near the intersection with Tamphery Creek Road, north of Big Sky.

At 10:07 a.m. on Saturday, October 12, 2024, a caller reported discovering a deceased male in a tent approximately 2.5 miles up Moose Creek Road. The caller indicated that the death may have been caused by a bear attack. Units from the Gallatin County Sheriff’s Office, Montana Fish, Wildlife and Parks, U.S. Forest Service, Montana Highway Patrol, and Big Sky Fire Department responded to the location.

A Montana FWP agent with expertise in bear attacks responded and did not find any signs of bear activity at the scene. This prompted investigators to treat the case as a homicide. Evidence gathered through an autopsy further indicated that this was a homicide.

The victim has been identified as 35-year-old Dustin Mitchell Kjersem, 35, of Belgrade, Montana.
