Authorities say a motorist who got into a fight with people whose car had overturned is suspected of later running down and killing one of them in Colorado.

The Colorado State Patrol said Wednesday that 21-year-old Jesse Plouvier of Canyon City is facing charges of vehicular homicide after the hit-and-run incident early Sunday near Florence.

The death came after a vehicle slid off the road and overturned. The three people inside flagged down passing motorists for assistance and said Plouvier refused to give them a ride and drove off.

Trooper Josh Lewis said the three people kept trying to get help until one was struck and killed.

Lewis said investigators identified Plouvier as the driver following a tip that led to a search of his home. It could not be immediately determined if he had a lawyer.
