Augustine John Dellea, known by his middle name John, was 51 when he was last seen in San Francisco on January 27, 1998. He is described as a white male with black hair, brown eyes, about 6 feet 0 inches tall and 150 pounds; he may have had a full beard and was wearing a black jacket and blue jeans at the time.

For many years the San Francisco Police Department treated his case as an active missing person investigation. At an unspecified time the California Department of Justice updated its records to show Augustine John Dellea Jr. is no longer considered a missing person, but no public details explain that change.

If anyone knew John Dellea or has information about his whereabouts or what happened after January 27, 1998, please share what is known.
