On the evening of March 24, 2011, a dispute between neighbors in Temple Hills, Maryland, turned deadly. Gregory Lucious Lawton Jr., 31, was found with gunshot wounds in the entrance of the building where he lived on the 4400 block of 23rd Parkway. Officers who responded to a shooting call at about 9:35 p.m. pronounced Lawton dead at the scene.

Prince George’s County investigators say the shooting arose from a dispute with a neighbor identified as 29-year-old James Allen Payne. Police allege Payne produced a handgun and shot Lawton. Lawton, known to friends as Lil G, was a father of three and worked as a security guard; his family described him as a good Samaritan trying to improve community safety.

An arrest warrant for first-degree murder was obtained for James Allen Payne, and he turned himself in on March 25, 2011. Anyone with information about the case or who knew Lawton is asked to come forward.
