On January 6, 2021, 31-year-old Justin Sumlar of Jacksonville was shot and killed outside an auto shop on Edison Avenue in the Mixon Town area. The shooting occurred in broad daylight while Sumlar was standing in front of the shop with several other people; he was pronounced dead at the scene after being struck multiple times.

Witnesses said a man in a gray hooded sweatshirt approached and fired nine shots, seven hitting Sumlar. After the shooting, witnesses reported a black Nissan with a Texas license plate leaving the scene erratically. Officers located the vehicle, which became the subject of a pursuit that ended in a crash; a .45-caliber handgun was thrown from the car. The driver, Delquan McGriff, and the shooter, identified as Greggory James III, were taken into custody. Ballistics and DNA evidence from a sweatshirt were reported to link James to the shooting.

Investigators described a possible dispute, potentially over money, as a motive. Does anyone have information about Sumlar, his movements that day, or contacts who might shed light on the dispute?
