On the evening of November 3, 1985, 31-year-old Martin Williams answered a knock at his home on the 4500 block of Leaf Court in Denver. An unknown person shot Williams after the door was opened. He was taken to St. Anthony Hospital but died there the same day; the death was ruled a homicide and the Denver Police Department opened an investigation.

Decades later the case remains unsolved. The shooter who knocked on the door and fired the fatal shot has not been identified, and no arrests have been announced. Anyone with memories of the neighborhood or information about that night is asked to contact investigators.?
