Selena Marie Edon, 29, was last seen on October 28, 1991, at a hospital in San Francisco after a traumatic motorcycle crash in November 1989 left her with brain damage, memory loss and a crushed left thigh. She lived with her mother in San Diego for part of her recovery, returned to San Francisco in May 1990, and kept regular contact with family until an evasive October 1991 phone call in which she told her mother to worry if she didn’t hear from her within a month or two.

Shortly after that call Selena disappeared. A private investigator hired by the family reported possible sightings in San Francisco’s Tenderloin district, but none were confirmed. Her family believes her mental-health issues and memory problems may have caused her to lose awareness of her identity. There have been no significant leads since her disappearance.

Anyone who knew Selena, saw someone matching her description in late 1991, or has information that could help locate her is asked to come forward.
