Bishop was last seen near a nightclub on Butternut Street in Abilene, Texas on October 2, 1981. She has never been heard from again. Authorities regarded Henry Lee Lucas as a possible suspect in Bishop's case. A photo of Lucas is posted below this case summary. Investigators interviewed him at least ten times, but Lucas consistently denied involvement in Bishop's disappearance.

Lucas was convicted of the 1979 murder of an unidentified female in Texas and sentenced to death. The state's former governor, George W. Bush, commuted his sentence to life imprisonment prior to Lucas's scheduled 1999 execution. He later died in prison. Lucas claimed to have killed approximately 600 people, but he confessed to many crimes he did not commit and the exact number of his victims is unknown. Bishop's case remains unsolved.
