John Haywood Barreto was 35 when he was last heard from on January 20, 1977. A Lake Oswego, Oregon, resident, his final known contact came when his family wired him money in Miami, Florida. After that communication there have been no confirmed sightings or contacts.

Known to travel aimlessly in warmer climates, John commonly rode Trailways or Greyhound buses. He received disability payments that were deposited to an account his mother could access and would call her periodically to request money. Reports say he struggled with mental health issues after experimenting with LSD while in the U.S. Army.

John was described as having brown hair (worn at times crew cut, long, or shaved), red facial hair, bright blue eyes, standing between 5 feet 9 inches and 5 feet 11 inches and weighing about 160 pounds. He had scars from an appendectomy on his abdomen, a scar down his right arm, and a large scar on the left side of his chest. He typically wore a solid-colored shirt, blue jeans without a belt, and loafer-style shoes.

The Lake Oswego Police Department is handling the case and it remains open. If anyone knew John, saw him in Miami around January 20, 1977, or has information about his travels, please come forward.
