COLUMBUS, Neb. (AP) — An 83-year-old woman has died after her vehicle accelerated out of a truck stop carwash and struck the side of a ditch in Columbus.

The accident occurred around 8:40 a.m. Tuesday at the Sapp Bros. truck stop.

Police say Donna Wyman, of Silver Creek, was going through the carwash in her sport utility vehicle but failed to stop at its final step. Her vehicle accelerated out of the carwash, crashed through a fence and struck the ditch side.

Police Capt. Charles Sherer says crash investigators will be checking for any mechanical failure and whether Wyman suffered a medical problem that led to the crash.

Platte County Attorney Carl Hart says there was no indication that Wyman had any medical issues.
