Antwuan Roach was 18 when he was fatally shot while walking alone and unarmed in Northeast Washington, D.C., on Friday, May 22, 2020, at about 4:50 p.m. He was pronounced dead at the scene and taken to the Office of the Chief Medical Examiner.

Investigators identified a 16-year-old suspect, Michael Mason, who they say had tracked Roach to that location. Court documents assert the killing was tied to a gang rivalry; Mason reportedly regarded Roach as a rival gang member and the two had exchanged verbal confrontations while in juvenile detention. Mason was arrested on June 17, 2020, and charged as an adult with first-degree murder while armed in Roach’s death and in an unrelated April 2020 killing.

Does anyone have information about Roach’s life in the neighborhood or the alley behind East Capitol Street that could help fill in what happened that afternoon?
