On the afternoon of September 1, 2016, 17-year-old Kevin Anthony Jackson II was fatally shot in the 1900 block of 16th Street SE in Southeast Washington, D.C. The shooting occurred about 2:15 p.m.; Jackson suffered a gunshot wound to the head, was taken to a nearby hospital, and died shortly after arrival.

Police say the attack grew out of a dispute between rival neighborhood crews. Investigators report prior altercations between Jackson and the alleged shooter, and a witness told detectives Jackson and others had assaulted the suspect months earlier. Security video reportedly shows a male approaching the scene touching what looked like the handle of a gun in his waistband. Four shell casings were recovered.

A 15-year-old male was arrested at school and charged with first-degree murder while armed; he was charged as a juvenile and ordered to be detained with the District’s Department of Youth Rehabilitation Services. A separate shooting of a pizza delivery driver nearby was later determined to be unrelated. Does anyone have information about Kevin, the neighborhood crews, or the events that led up to that afternoon?
