A teenager girl from western Harrison County was killed Sunday, after the vehicle she was in was hit by a train. The Iowa State Patrol says 16-year-old Cailey Marie Berndt, from Little Sioux, was traveling westbound on 125th Street near County Road K-45 around noon Sunday, when she failed to yield to a northbound Union Pacific train. After the 2005 Pontiac G-6 she was driving was hit by the locomotive, it was tossed  into the Harrison/Monona Waterway. Berndt was flown by medical helicopter to the University of Nebraska Medical Center, where she died shortly after arrival. The Patrol says she was not wearing a seat belt. The accident remains under investigation by both the Iowa State Patrol and the Union Pacific Railroad.
