Mario Barraza-Murillo was 59 when he was last seen in Thornton, Colorado on January 31, 2009. He’s described as six feet tall, about 140 pounds, with gray or partly gray hair and green eyes. He is diabetic and dependent on insulin, which made his disappearance especially urgent from the start.

The Thornton Police Department filed the case under agency number 2009-002757 and has kept it open. Public details about his last movements or what he was wearing that day have not been widely released, leaving key gaps in the timeline of his disappearance.

If anyone in Thornton in late January 2009 remembers seeing Mario or has information about his whereabouts, please come forward. What did Mario do or where might he have gone in those days before he was reported missing?
