Matthew Naaf, 23, of San Francisco was last seen on December 31, 2013. Before he disappeared he’d been having personal problems: difficulties with school, financial strain and the end of a romantic relationship. Those issues had put him on the verge of moving back in with his parents.

On the day he vanished Matthew sent a friend a photo of himself taken on the Golden Gate Bridge and was last heard from then. At the time he was wearing a blue sweater and blue jeans and had scars near both Achilles areas from surgeries for bilateral clubfoot. The San Francisco Police Department and his family have continued to investigate, but very little has emerged about his fate since that last contact.

If anyone saw Matthew on December 31, 2013, or has information about his whereabouts, please share what is known.
