A Nebraska woman was killed over the weekend in a single-vehicle accident on a rural road in western Iowa’s Cass County. The Iowa State Patrol says 51-year-old Diana Simet, of Lincoln, Nebraska died, when for reasons unknown, her car went out of control, entered a ditch hit a field drive and went airborne, about three-miles south of Cumberland on County Road N-28.

Simet — who was not wearing a seatbelt — was ejected from the 1998 Mercury Grand Marquis, and was pronounced dead at the scene. The accident, which occurred at around 6:35-p.m. Saturday, remains under investigation.

There were at least five other accidents earlier in the day on Interstate 80 in western Iowa, as motorists dealt with snow and sleet on the highway.
