Brenda Joan Szabo was 33 when she was last seen in San Diego County, California, on October 1, 1983. She was described as a white female, 5 feet 4 inches tall, 120 pounds, with light brown hair, blue eyes and a left wrist tattoo of a Harley motorcycle without wheels; she reportedly had other tattoos and past fractures to an arm, leg, finger and back.

Szabo led a turbulent life before her disappearance: she ran away from home in Dallas in 1966, gave birth to four children who were placed for adoption, used aliases including Karen Blaha and Brenda Miller, and had arrests and jail time tied to drug use and sex work. In the early 1980s she appeared to be stabilizing—enrolling in community college in the Antelope Valley, studying wildlife and forestry, working as a dog groomer and reportedly stopping drug use—but she was jailed for a probation violation and later told family she planned to visit Dallas and would be in touch. She never arrived and was not heard from again; a daughter formally reported her missing in 2005 after seeing an article about unsolved San Diego County murders. Investigators have kept the case active, and some believe she may have assumed a new identity.

Did anyone in San Diego or Dallas know Brenda around 1983 or see someone matching her description after October 1, 1983?
