Leonard McAdoo, a 30-year-old Black man, was found shot to death in the parking lot of the Aladdin Theater near East Colfax Avenue and Race Street in Denver in the early morning hours of July 3, 1974. McAdoo had been at a local tavern earlier that evening, and the on-scene investigation by the Denver Police Department determined he died from gunshot wounds.

The circumstances that led to the shooting and any motive were not immediately clear, and the investigation at the time did not identify or apprehend suspects. The case went cold and remains unsolved; the Denver Police Cold Case Unit still retains the file and seeks information that could lead to an arrest and prosecution.

Anyone with information about Leonard McAdoo, his movements that night, or the Aladdin Theater area in July 1974 is urged to come forward.
