Authorities say the victim of last week’s deadly car/train collision near Dyersville may have been impaired. The Dubuque County Sheriff’s Office says a preliminary investigation has revealed that 62-year old Mary Bouillion of Coralville was impaired at the time of the accident, which may have been a contributing factor. Bouillion had driven her car onto a private driveway at the end of Olde Hawkeye Road during the early morning hours on November 26th, and her car became stuck on the railroad tracks. A train hit her car head-on and Bouillion died two days later from her injuries at University of Iowa Hospitals and Clinics. The Sheriff’s Office says there is no indication that Bouillion was using GPS or another other electronic navigational equipment at the time of the accident, so it was not a contributing factor. The Sheriff’s Office and the Canadian National Railroad are continuing to investigate.
