Elizabeth Diane Vaughn, known as Diane, was 28 when she disappeared from Gallatin, Tennessee, in the early summer of 1992. She had recently separated from her husband, moved to Hendersonville with their young daughter, and was in the middle of divorce proceedings and a new relationship. On June 18, 1992, after her estranged husband, Bruce M. Vaughn, picked up their daughter, Diane told a cousin she was going to Bruce’s home in White House to get the child. Bruce later told police Diane had come to his house, they argued, and she left saying she would get gas and dinner before returning to her apartment and planned to visit her cousin that evening — a visit she never made.

Her blue 1991 Ford Tempo was found abandoned June 20, 1992, outside an O’Charley’s at Rivergate Mall in Goodlettsville. One restaurant employee thought they saw Diane at the bar that night, and an unconfirmed witness later claimed to have seen a woman matching her description get into a red 1980s pickup with a man with shoulder-length red hair and a beard.

Investigators consider Diane a likely homicide victim, but without remains or conclusive evidence the case remains unsolved. Did anyone in the Gallatin or Rivergate Mall area remember seeing Diane or that red pickup truck on June 18, 1992?
