Mark Marvin, 39, was last seen in San Francisco on October 6, 2011. He lived with his partner in the 200 block of Divisadero Street; when the partner returned home in the early hours of October 7, Mark was not there and a missing persons report was filed on October 8.

Mark’s black 2009 BMW was found abandoned at Baker Beach on October 9 with his wallet, keys, and money still inside. Investigators noted the driver seat was positioned for someone taller than Mark, prompting questions about whether someone else drove the car to the beach. He had a history of prescription drug abuse and had attended a rehab facility in Arizona but was reportedly showing improvement after returning and was unhappy at work because of a wage reduction.

The circumstances of his disappearance remain unclear and the case is unsolved. Does anyone who knew Mark or who was near Baker Beach on October 9 have information that could help?
