Andrea Joy Hall, an 18-year-old White female, was last seen hitchhiking on July 8, 1979, along the Pacific Coast Highway in Redondo Beach, California. She was picked up by two men later identified as Lawrence Sigmund Bittaker and Roy Lewis Norris.

According to confessions attributed to those men, Hall was taken to a remote fire road in the San Gabriel Mountains overlooking Glendora, strangled, and her body was thrown from a cliff. Her remains have never been recovered. At the time she disappeared she was wearing a one-piece burgundy bathing suit and blue terry cloth shorts, had a two-inch scar on her tailbone, and may have sustained injuries to both sides of her skull.

Lawrence Bittaker and Roy Norris were later arrested and convicted for the abduction and murder of Hall and several other young women. Despite those convictions, Hall’s body has not been found and she remains officially listed as a missing person.

If anyone knew Andrea, saw her that day, or has information about the San Gabriel Mountains area where she was reportedly taken, please come forward.
