The vehicle crossed the roadway and left the roadway to the left, entering a steep ditch and cornfield and overturned, ejecting the victim from the vehicle. The vehicle came to rest on its wheels approximately 30 yards off the roadway in a plowed farm field.

The crash remains under investigation by the Columbia County Sheriff’s Office and Columbia County Medical Examiner’s Office. Halverson was not wearing a seatbelt at the time of the crash. Alcohol and Speed does not appear to be a factor.

According to the release, Halverson was driving from the right front passenger seat because she was a rural route delivery person with the U.S. Postal Service.
