LINCOLN, Neb. (AP) — A 21-year-old northeastern Nebraska man has been killed in a fiery crash involving two semitrailers on U.S. Highway 77 just north of Lincoln.

The Lancaster County Sheriff’s Office says Brandon Gerdes, of Osmond, was driving a grain truck south on the highway when he was broadsided by a semi hauling rock.

Investigators say the grain truck rolled onto its side and burst into flames. Gerdes was pronounced dead at the scene.

Officials say the driver of the rock truck, 67-year-old Gary Jacobsen of Garland, was taken to a hospital with critical injuries. Officials say he is expected to survive.
