Montana Highway Patrol Trooper Lath Keith was a man with a lot on his mind on Thursday.

Keith was called Thursday morning to a motorcycle crash on West Fork road, where the rider had struck a deer on the roadway.

"Just as he was being transported to Marcus Daly Hospital, I got the call for a fatal rollover crash on Highway 93 South," Keith said.

That call came in to 9-1-1 at about 11 a.m. and Keith, who was the sold Montana Highway Patrol Trooper on duty in the area, responded to the scene.

"It was a one-vehicle rollover," Keith said. "The car was southbound on U.S. 93 when it traveled off the left shoulder of the road and lost control and the vehicle overturned multiple times down an embankment into a field," Keith said. "There were four occupants in the vehicle. Three sustained injuries, two were taken to Marcus Daly Hospital in Hamilton and a third was transported to St. Pat's. The fourth individual was a fatality. He was a male, and was not the driver."

Keith said the car and its occupants were from western Montana, and everyone was wearing a seat belt. He said there was no indication that alcohol played a part in the fatal crash, and whether speed was a factor is still under investigation.

The name of the victim, a male in the 20's, will not be released until his family has been notified.

The Ravalli County Sheriff's Office assisted in the crash investigation.

Keith said the injured motorcyclist was wearing a helmet and was treated and released from Marcus Daly Hospital.
