NORFOLK, Neb. (AP) — A 57-year-old man has been injured while changing a tire for two stranded motorists in northeast Nebraska.

The accident occurred about 7 p.m. Sunday on U.S. Highway 275 east of Norfolk. Stanton County Sheriff Mike Unger says a van had stopped with a flat tire in the outside westbound lane of the highway. Jeffrey Bethards, of rural Pilger (PIHL’-gur), had stopped his vehicle behind the van before getting out to help the two motorists.

Unger says a westbound car driven by Nick Beckman, of Norfolk, struck Bethards’ vehicle, then him and then sideswiped the van. Bethards was flown to Mercy Medical Center in Sioux City, Iowa. The two motorists were taken to a Norfolk hospital. Beckman was treated at the scene.
