Keon Marquis Tucker, 23, was killed by gunfire in Columbia, South Carolina, on the night of Saturday, December 21, 2019. He had been attending a gathering on Norman Street after a funeral for another young man when shots rang out; Tucker was found outside a residence with fatal gunshot wounds to his upper body and was pronounced dead at the scene.

Columbia police, on patrol at the time, heard the shots and responded to a ShotSpotter alert that located the incident. Investigators encountered a large, hostile crowd; the department described the shooting as gang-related. The Midlands Gang Task Force was assigned to the investigation and police asked the public for help identifying those responsible, but witnesses at the large gathering did not provide usable information.

As of late 2025 the case remains listed as unsolved on the Columbia Police Department cold case roster, with no arrests or publicly identified suspects. If anyone knew Keon, was at that gathering, or has information that could help, please contact investigators.
