A Hamburg man was seriously injured during an accident Saturday in Fremont County. The Sheriff’s Office reports deputies were called to the scene of a single-vehicle, rollover accident just west of Riverton, on 250th St. Upon their arrival, they found 21-year old Dayne Andrew Sturm, trapped inside his vehicle, that was under water.

Sturm was unconscious and transported to Grape Community Hospital in Hamburg by Riverton Fire and Rescue. He was later transported to the University of Nebraska Medical Center, in Omaha.

An investigation into the crash continues, but authorities said alcohol was believed to have been a factor.
