A Swift Current driver is the victim of a fatal hit-and-run in Great Falls, Montana, over the long weekend.

The Montana Highway Patrol says Marvin Knutson, 72, died after being hit by a semi tractor-trailer.

Authorities are searching for the driver of the tractor-trailer, who left the scene of the incident.

The Great Falls Tribune is reporting that the tractor-trailer was hauling two-by-four pieces of lumber. They say the driver of the tractor-trailer pulled in front of Knutson’s van, pushing him off the road.
