Summary based on the NamUs case record (MP28993) and 3 other sources
Matthew Naaf, a 23-year-old man from San Francisco, California, was last seen on December 31, 2013. Prior to his disappearance, he had been experiencing personal difficulties, including struggles with school, financial issues, and the end of a romantic relationship. These challenges had led him to the prospect of moving back in with his parents. On the day he was last seen, Matthew sent a friend a photo of himself taken on the Golden Gate Bridge. He has not been heard from since.

At the time of his disappearance, Matthew was wearing a blue sweater and blue jeans. He has distinguishing scars near his Achilles areas due to surgeries on both feet for bilateral clubfoot. Despite ongoing efforts by the San Francisco Police Department and the involvement of his family, very little information has surfaced regarding his fate since that final communication. Investigators continue to seek information to help solve the case, which remains unsolved.
Last Seen: Dec 26, 2013
