William Barnett Cassada, 36, was last seen October 4, 1989, in Pacific Grove, California. He had been experiencing severe depression, paranoia and delusions and reportedly believed he was working for the CIA. He was not taking required psychiatric medication at the time and was also suffering from a mild case of pneumonia.

On the day he vanished Cassada showed his mother a large amount of cash and then disappeared. A private investigator hired by the family traced him only as far as a homeless shelter in Washington, D.C.; his movements after that are unknown. He was later declared legally dead, but the disappearance remains unsolved and the case is open.

Anyone with information about William Cassada’s whereabouts is asked to contact the Pacific Grove Police Department.
