William Heaney was 39 when he was shot during a robbery attempt at the Cheerio Lounge, 1997 S. Federal Blvd., in Denver in the early morning hours of a chilly November day in 1975. An unknown assailant entered the bar and fired a shot that struck Heaney. He was rushed to a local hospital and survived for about a month before dying of the gunshot wound on December 22, 1975.

The shooter has never been identified and no arrests have been made; the case is classified as a cold homicide. Investigators continue to seek anyone who might have information that could lead to a break in the case.

Did anyone who was in or near the Cheerio Lounge in November 1975 see or remember anything that could help finally identify the person who entered that morning?
