The Tennessee Highway Patrol says a single vehicle crash in White County Saturday night (December 2, 2017) killed a 3-year-old boy and left a 10-month-old girl injured. Troopers say the crash took place on Highway 70 East when a 2011 Ford left the roadway, went over the embankment and struck another embankment. The identity of the 25-year-old female driver was not released. She was transported to Vanderbilt Medical Center along with a 10-month-old child inside the vehicle. A three year-old was pronounced deceased. Authorities said child restraint devices were in place, but not properly used at the time of the crash.
