On the evening of October 16, 1980, 32-year-old Terry Snyder left to show a vacant residence on the 1600 block of South Humboldt Street in Denver, Colorado. Snyder worked as the store manager for Downing Appliances and was performing that duty when he failed to return home that night. Responding officers found him inside the house; he had been shot to death.

Decades later the killing remains an unsolved cold case. Investigators have not publicly identified suspects or made any arrests, and the Denver Police Department continues to ask the public for information that could lead to a breakthrough. The circumstances of the showing and any contacts Snyder had that evening are central to the unanswered questions.

If anyone remembers Terry, the vacant Humboldt Street residence, or saw anything unusual on October 16, 1980, please contact investigators with information.
