Kerby R. Acosta was 17 when he was killed outside 4500 Mariposa Street in Denver on July 13, 1997. Witnesses say he was with friends when a vehicle drove past and someone inside fired a shotgun; Kerby was struck and died at the scene. One report identifies him as Hispanic/Latino.

The car reportedly fled with several occupants. Denver Police opened a homicide investigation and later the case was assigned to the Cold Case Unit, but no one has been publicly identified or arrested in connection with the killing. A reward has been offered for information leading to an arrest.

Does anyone who was in that neighborhood on July 13, 1997, or who remembers hearing about this shooting, have information that could help investigators?
