Highway Patrol troopers say they don't know why a Waverly man drove off US 169 yesterday morning, causing a crash that ended his life. 55-year old Jerry Hughes was not wearing a seat belt, according to a KHP online crash report. The fatal crash happened just south of Iola about 9:35 yesterday morning. Troopers say Hughes was southbound in a 2010 Nissan when he left the road for an unknown reason, drove through two fences and two fields, and struck a tree. He was taken to Allen County Hospital, but died of his injuries.
