A Chillicothe teen had serious injuries in a single-vehicle accident in Grundy County Wednesday evening. State Troopers report the 17-year-old boy was northbound on NW 22nd Avenue, north of Trenton when his vehicle began sliding off the right side of the road. The vehicle struck the ditch and began overturning. The teen was not wearing a safety belt and was taken to Wright Memorial Hospital in Trenton and later to St. Luke’s on the Plaza for treatment.
