Rangers responded to a single-vehicle accident on U.S. 441 on the afternoon of April 15th. Terry Fox, 45, of Gatlinburg was heading north on the road when his 2005 Dodge Caravan left the road just north of the tunnel and struck a guardrail on the left side of the road in the turn lane for the Flat Branch Road exit. The Caravan sustained only minor damage, but enough to make it necessary for Gatlinburg EMS personnel to break into the vehicle to reach Fox. He was taken by ambulance to the Fort Sanders Sevier Medical Center, where he was later pronounced dead. Given the very minor damage to the vehicle, rangers are investigating the possibility that a medical condition may have caused the accident and his death. The county medical examiner will conduct an autopsy to make that determination.
