John Haywood Barreto was 35 when he was last heard from on January 20, 1977, in Miami, Florida. The final known contact was a request for money: his family wired him funds to cover expenses. His family is from Lake Oswego, Oregon, and the Lake Oswego Police Department is handling the investigation.

Barreto served in the U.S. Army and reportedly developed a mental illness after experimenting with LSD. That condition led him to travel aimlessly, especially in warm weather, often riding Trailways or Greyhound buses. At the time he disappeared he was receiving disability payments; those benefits were deposited into an account his mother could access and she would wire him money when he asked.

Descriptions vary: he is a white male with blue eyes and brown hair that he may have worn long, in a crew cut, or shaved, and he may have had red facial hair or a beard. Reported height ranges from 5 feet 9 inches to 6 feet 2 inches and weight from 160 to 185 pounds. Distinguishing marks include a burn scar on the left side of his chest, a prominent scar down his right arm, and an appendectomy scar. Dental records, DNA, and fingerprints are available for identification. There are few details about the exact circumstances of his disappearance; does anyone remember seeing him on a bus or in Florida around January 1977?
