John Carrillo, 66, was found shot to death on the evening of November 29, 1977, lying on the sidewalk near the intersection of 24th and Stout Streets in Denver. A passerby discovered him and called for help; responding police and medical personnel recorded the scene in the 2400 block of Stout Street and opened a homicide investigation after determining he had been fatally shot. The assailant had already fled before first responders arrived, and no suspect description was developed that night.

The file remains open with the Denver Cold Case Unit and in Colorado’s statewide cold case database; authorities continue to seek information and no arrests or publicly named suspects have been announced. Anyone with information about John Carrillo or that night is asked to come forward.
