Joseph Gulliver was 60 when he was last seen in San Francisco on August 27, 2012, and has not been heard from since. He is a white male, 6 feet 3 inches tall, about 180 pounds, with gray hair and brown eyes. Authorities say he may also use the alias Joe Balducci and have classified him as an endangered missing person because of a history of depression.

Few details about the circumstances of his disappearance have been released. The specific location in San Francisco where he was last seen, what he was wearing, and who last saw him are not publicly known. The San Francisco Police Department is listed as the reporting agency and the case remains unresolved.

If anyone knew Joseph, knew him as Joe Balducci, or has information about his last known whereabouts, please share what you can with investigators.
