A shooting on the late afternoon of July 28, 2015, killed 31-year-old Melvin Joshua Williams in the Woodland Terrace neighborhood of Southeast Washington, D.C. At approximately 5:16 p.m., Williams was found in the rear of the 2300 block of Ainger Place, SE, with gunshot wounds and emergency personnel found no signs of life. An autopsy determined Williams was struck once on the right side of his head by a large-caliber round fired from a distance, likely from an assault rifle.

Investigators recovered multiple spent casings from at least two different guns across a courtyard 100 to 150 yards from where the body was found. The Metropolitan Police Department’s Homicide Branch sought public help and offered a reward; witness accounts helped shape the inquiry. On August 19, 2015, Derrick Carter, 26, was arrested and charged with second-degree murder while armed after witnesses placed him carrying a long gun and walking toward the shooting. A second man, Tyrale Diontaye Johnson, also known as Darrell M. Johnson, was later arrested and charged; an arrest warrant alleges he was seen with a handgun and braced Carter as the fatal shot was fired. Both men were held without bail.

Does anyone have information about Williams, the scene on Ainger Place, or the individuals seen in Woodland Terrace that afternoon?
