24-year old Katherine M. Adams of Nashville, Illinois died very early Saturday morning after she had been in a one-vehicle accident.  According to Jefferson County Coroner Eddie Joe Marks, the accident occurred on Route 15, but the Washington County Sheriff’s deputies responded.  Also, his office was called to the scene.  According to Marks, it is believed that Adams lost consciousness for some reason and the vehicle went off the road.  She was taken to Crossroads Community Hospital, where she was pronounced dead.  Marks says there was not blunt force trauma that would have caused her injury and it is still under investigation, as they await toxicology test results.  The Washington County Sheriff’s Office has not made their report available to the public.
