Addington was in Tulsa, Oklahoma in May 1984 to prepare for her wedding, which was scheduled for May 19. She was a resident of Dallas, Texas at the time. Addington attended a bachelorette party that a group of friends threw for her during the evening of May 15 at The Great Escape Club on 21st Street and Garnett Road in Tulsa. Her friends departed from the club at approximately midnight, but Addington chose to stay behind and find another ride home.

Addington's friends last saw her speaking to an unidentified Caucasian male inside the club. He was in his mid-twenties with collar-length brown hair parted in the center. The man was approximately 6'0" and 160 pounds with a medium build. He was wearing a green shirt.

Addington never arrived home that evening and has not been heard from again. Tulsa investigators have classified her disappearance as a suspected homicide. Her case remains unsolved.
Lisa is described as a white female, 22 years old, 5'8" tall and 125 pounds, with brown hair and green eyes. Last seen wearing a black, red, and blue plaid shirt with black pants and white knee-high socks.
