D.C. police arrested one of two suspects Saturday in the Dec. 26 fatal shooting of a man outside a 7-Eleven store in the District’s Takoma neighborhood.

Shawn J. Brown, 28, of Northwest Washington, was charged with second-degree murder while armed, police said Sunday. He was arrested on a warrant by members of the Capital Area Regional Fugitive Task Force.

Police said the shooting happened about 7:45 p.m. in the 200 block of Cedar Street NW. The victim, James Dorsey Jr., 37, of no fixed address, died at a hospital. Police have not commented on a possible motive.

The arrest comes several days after police released a surveillance video that shows men arguing inside the store, then a group of men outside in the store’s parking lot. A man in a green sweatshirt is seen confronting two men with what appears to be a chain. The men back away, and then others converge and fight. The video does not show the shooting.
