Larry Gene Loucka, 28, was shot and killed while walking along the 400 block of E. 11th Avenue in Denver on the night of September 8, 1974. Known to friends as Smiles, he had recently returned to Denver after spending time in Phoenix and was carrying a portable radio when an unknown person followed him, approached from behind, and shot him. He was taken to a hospital and died of his wounds in the early hours of September 9, 1974.

The Denver Police Department investigated but no suspects were publicly identified and no arrests have been announced. The case went cold and remains unsolved. If anyone has information about that night or about who followed Larry before the shooting, please share what is known with investigators.
