Carlos Balderrama was 32 when he was shot and killed after a house party in Denver on the night of July 17, 1973. He had spent the evening playing pool at the Alpine Inn and went from there to a party near West 35th Avenue and Pecos Street. An argument at that gathering escalated and an unknown person fired the fatal shot.

The Denver Police Department opened a homicide investigation (case number 73-104948), but no suspect was identified and no arrests were made. The killing remains an unsolved cold case and the file is still listed as open.

If anyone has memories of that neighborhood, the Alpine Inn, or the party that night, can you share information that might help bring answers to the family?
