Tanya Ruiz was 24 when she was last seen on August 6, 1975, at Edwards Ranch near Piru, California, where she lived with her husband. She had been visiting her grandmother for a few days and was expected to meet her that Sunday for a church event but never arrived. Tanya’s family searched and, about a month later, her mother reported her missing to authorities.

When police questioned her husband he reportedly showed little concern and said Tanya had left with about $150 to $200 and some clothing. No substantial leads developed. In 1979 the husband was later implicated in the murders of his subsequent wife and stepson; their bodies were found buried in his backyard. Tanya’s body has never been found and her disappearance remains unsolved.
