A 33-year-old Townsend man died at the scene of a one-vehicle rollover southeast of Helena near Winston early Monday morning.
The man, whose name has not been released pending notification of family, was not wearing a seat belt and was ejected from the Toyota 4Runner, according to Montana Highway Patrol Trooper Tim Proctor.
Investigators are not sure what time the accident occurred. A trooper located the vehicle in a field off Highway 12 just before 7 a.m., Proctor said.
The man was the only occupant in the vehicle, which was found upside down. The cause of the accident is under investigation.
Proctor said he does not believe speed was a factor in the rollover or if alcohol was involved.
