Katrina Ashford was 18 when she vanished from San Rafael, California, on July 11, 1972. Her parents last saw her that day; three days later her car was found abandoned in nearby Marin County. At the time she was 5 feet tall, about 130 pounds, with black hair and brown eyes.

Investigators recovered the vehicle and pursued inquiries, but very little information has emerged over the decades. There have been unconfirmed suspicions that she may have been connected to a prostitution ring in the San Francisco area, yet no definitive leads have been reported and the case remains unsolved.

Does anyone who lived in Marin or San Rafael in July 1972 remember seeing Katrina or her car, or have information that could help the Marin County Sheriff’s Office?
