Summary based on the NamUs case record (MP37661) and 7 other sources
Tanya Ruiz, a 24-year-old woman, was last seen on August 6, 1975, at Edwards Ranch near Piru, California, where she lived with her husband. Tanya had spent the previous few days visiting her grandmother and was supposed to meet her on Sunday for a church event, but she never showed up. Her family, concerned when they couldn't reach her, began searching for her. A month later, her mother reported her missing to authorities.

When questioned by police, Tanya's husband showed little concern for her disappearance, claiming she had left with $150 to $200 and some clothing. Despite efforts to find her, no substantial leads emerged. The case took a darker turn in 1979 when her husband was implicated in the murders of his subsequent wife and stepson, whose bodies were found buried in his backyard. However, Tanya's body has never been found, and her disappearance remains an unsolved case.
