Allen Shannon, 30, was shot and killed on December 29, 2003, at a residence at 1403 Carolina Avenue in Cincinnati, Ohio. He was pronounced dead on arrival at the hospital after the shooting. The Cincinnati Police Department investigated, and the Ohio Bureau of Criminal Investigation lists the case as an unsolved homicide.

No suspects have been identified or apprehended. The case attracted attention in part because Allen was the stepson of Ron Twitty, a former Cincinnati Police Department assistant police chief, a family connection that has been noted during the investigation. Authorities continue to ask anyone with information to call the tip line to help bring justice and closure to the family.

If anyone knew Allen, was in the area that night, or has information about who might have been at 1403 Carolina Avenue on December 29, 2003, please come forward.
