The Marshall County Sheriff says the father of a Britton man hurt in a hit-and-run accident over the weekend is offering a reward.

Fifty-year-old David Christenson of Britton was in guarded condition at a Fargo hospital Monday. His family wasn't releasing information about his injuries at that time.

Marshall County Sheriff Dale Elsen says Christenson's father is offering a $1,000 reward for information leading to the arrest and conviction of the person who hit the 50 year old Saturday night.

Investigators don't have a specific car they're looking for but say evidence leads them to believe it's a small to mid-sized vehicle.
