The Laurel County Sheriff’s Office says deputies are trying to figure out what led to a deadly single-vehicle crash along London Dock Road in London Tuesday. Officials say the car went over an embankment. Investigators say 74-year-old Lynda Ashley Gentry, of Powell Tennessee, was identified as the woman killed in the crash. Gentry was reported missing by the Knoxville Police Department on Sunday. There was only minor damage to her car and officials say they believe she died as a result of cold temperatures. The investigation is continuing.
