Diana left her Fulton, Mississippi home in 1981. The last time she contacted her family was on May 1, 1982. She was in Fontana, California at the time. She has never been heard from again. She may have traveled to Las Vegas, Nevada or Seattle, Washington after her disappearance. Her dental records were destroyed in a fire, meaning it would be difficult to link any unidentified remains to her. Washington state authorities are investigating her case, which remains unsolved. Diana has a mole on her left cheek and a scar on her right leg. She may use the last names Johnson and/or Smith.
