Authorities have identified Matthew Morgan Plympton, 20, of Darby, as the man shot and killed by the Darby town marshal during a disturbance call early Saturday.
Plympton died at a residence in downtown Darby after fighting with Town Marshal Larry Rose and trying to take the officer's firearm, according to the Ravalli County Sheriff's Office.
Rose had been dispatched by the county 9-1-1 center to a report of a domestic disturbance involving a man and a woman at about 1:25 a.m. Saturday.
Upon arriving at the scene, Rose was attacked by Plympton, who reportedly had been drinking and had assaulted his girlfriend, Sheriff Chris Hoffman said.
The two men struggled, and Rose ultimately was able to draw his weapon and shoot Plympton, Hoffman said.
The death is under investigation by Powell County civilian coroner John Pohle. The shooting is being investigated by the Ravalli County Sheriff's Office.
Rose, 62, sustained several cuts and a possible back injury during the fight. He was transported to Marcus Daly Memorial Hospital in Hamilton where he was treated and released.
After meeting with Darby Mayor Rick Scheele to discuss the shooting, Rose was placed on administrative leave for a week. Rose has been Darby's town marshal for more than 20 years.
In his absence, the Darby marshal's duties are being handled by the Ravalli County Sheriff's Office.
