On the evening of July 20, 2015, outside his apartment at Pembrook Court in Columbus, Georgia, 38-year-old Johann Gamble was shot and killed. The shooting occurred after a physical altercation between Gamble and a man identified as Andre Dixon. Gamble’s two daughters were inside the residence and witnessed the incident.

Witnesses told investigators that while Andre Dixon and Gamble were fighting, Andre’s brother Jeremy Dixon fired the fatal shot. Surveillance footage from a nearby grocery store placed the Dixon brothers in a green Mercury Marquis near the scene shortly before the shooting, and a distinctive tattoo on Jeremy Dixon’s left arm was used to help identify him.

Both Andre and Jeremy Dixon were arrested and charged in connection with the killing. Andre was charged with murder and simple battery; Jeremy faced charges including murder, aggravated assault, possession of a firearm during the commission of a crime, and possession of a firearm by a convicted felon. Andre Dixon entered a plea of not guilty to the murder charge.

Did anyone in Columbus see the green Mercury Marquis or have information about the events that night?
