Summary based on the NamUs case record (MP36018) and 4 other sources
William Barnett Cassada, aged 36, was last seen on October 4, 1989, in Pacific Grove, California. His disappearance was marked by troubling circumstances. Cassada had been struggling with severe depression, paranoia, and delusions, reportedly believing he was working for the CIA. He also required medication for his mental health, which he was not taking at the time, and was suffering from a mild case of pneumonia.

On the day he vanished, Cassada showed his mother a significant amount of cash, and soon after, he disappeared without a trace. Despite efforts to locate him, including the work of a private investigator hired by his family, Cassada was only tracked as far as a homeless shelter in Washington, D.C. His whereabouts after that remain unknown. He was later declared legally dead, but the case remains unsolved with few details available to explain what happened to him.

Authorities are still seeking information regarding his case, which remains open. If anyone has information, they are encouraged to contact the Pacific Grove Police Department.
