Lisa Jane Borden was 19 when she was last seen by her family in Big Spring, Texas, in October 1979. She traveled to California soon after and made a phone call to relatives; her last known location was Lodi, California, on October 10, 1979. Borden was known to hitchhike and has not been heard from since that date.

A plane ticket her boyfriend mailed for her return to Texas was never retrieved, a detail investigators have highlighted as suggesting she may not have left voluntarily. Authorities believe she may have been taken against her will. An unconfirmed tip said she was working as a waitress in Amarillo, but that was never substantiated.

Borden is described as a white female, brown hair, brown eyes, 5 feet 8 inches, about 140 pounds, with a scar and metal screws in her left hand from a prior injury. The case remains an active missing person investigation. If anyone knew Lisa, saw her in October 1979, or has information about her whereabouts, please come forward.
