Guadalupe Gutierez Carlin was 63 when he was last seen in the summer of 1984 in Denver, Colorado; no exact date is known. He is described as a Hispanic/Latino male, 69 inches tall, about 180 pounds, with brown hair and brown eyes. Few specifics exist about his last movements, clothing, or belongings, and the Commerce City Police Department is handling the investigation. The lack of witnesses and an exact timeline has left the case cold and his family with unanswered questions.

Did anyone in Denver or Commerce City in 1984 have contact with Guadalupe or remember seeing him that summer?
