Summary based on the NamUs case record (MP12566) and 6 other sources
Mark Marvin, a 39-year-old from San Francisco, was last seen on October 6, 2011. He had been living with his partner in the 200 block of Divisadero Street. When his partner returned home in the early hours of October 7, Mark was not there. His partner initially assumed he might have stayed with a friend, but after not hearing from him, 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. The vehicle’s driver seat was positioned for someone taller than Mark, leading to speculation that someone else may have driven it to the location. Although Mark had been struggling with prescription drug abuse, having previously sought treatment at a rehabilitation facility in Arizona, he had shown signs of improvement after returning. However, he was reportedly unhappy with his job at the time due to a wage reduction.

The circumstances of his disappearance remain unclear, and his case is still unsolved. Despite extensive efforts, no concrete leads have emerged regarding what happened to Mark after October 6, 2011. Authorities continue to encourage anyone with information to come forward.
