The Tennessee Bureau of Investigation (TBI) is also looking for a maroon Toyota pickup truck with a full bed ladder rack and white buckets in the truck bed. The TBI received a tip in June from a source who saw the vehicle in the Beech Creek community near Ben Hill Road in the vicinity of the Wells' home in the late afternoon of June 14 or 15. 

The TBI is asking anyone with information about Wells’ whereabouts to call 1-800-TBI-FIND or contact the Hawkins County Sheriff’s Office at 423-272-7121.
