John Carrillo, 66, male, Hispanic, was discovered on the evening of November 29, 1977, lying on the sidewalk near the intersection of 24th and Stout Streets in Denver. A passerby spotted him and summoned help; responding police and medical personnel determined he had been shot to death. The scene was in the 2400 block of Stout Street, and the case was recorded that night by Denver authorities.
Investigators identified him as John Carrillo and opened a homicide investigation, noting that the assailant had fled before first responders arrived. Despite the urban location and the early notification to police, no immediate suspect description was developed in the hours that followed, and the case entered the city’s roster of unsolved homicides. Public records and memorial listings later reiterated the date, place, and manner of death, further anchoring the chronology of the killing.
Over the years, the case has remained open with Denver’s Cold Case Unit and in Colorado’s statewide cold case database. Authorities continue to appeal for information, but no arrests have been announced and no specific suspect or suspects have been publicly named. The file is still classified as an unsolved shooting homicide.
