(KLZA)--Speed appears to have been a factor in a fatal rollover crash that killed a Lewiston woman in rural Johnson County, Nebraska Tuesday afternoon.

A news release from Johnson County Attorney Rick Smith identifies the victim as 46-year-old Cheri Speckmann.

Smith says Speckmann’s vehicle left 612 Avenue south of Vesta and rolled several times. Speckmann was transported to the Johnson County Hospital in Tecumseh where she was pronounced dead.

Speckmann was the only occupant of the vehicle.

Sheriff Scott Walton said speed appeared to be a factor. Toxicology results are pending, but the wreck does not appear to be alcohol-releated according to the release.
