On the evening of September 4, 2021, multiple gunmen opened fire in the 600 block of Longfellow Street NW in Washington, D.C., striking participants at a neighborhood gathering. Twenty-four-year-old Keenan Braxton, a male resident of Northwest D.C., was among the victims and died at the scene. Two other people, Donnetta Dyson, 31, and Johnny Joyner, 37, were also killed; three additional people were wounded and survived.

Investigators identified a black Honda Accord as the vehicle used by the shooters and said multiple assailants exited the car and fired into the crowd at about 7:33 p.m. Authorities characterized the attack as a targeted retaliation tied to a rivalry between neighborhood crews. Arrests followed in the weeks and months after the shooting, with several people charged in connection to the attack and allegations that others helped destroy evidence and the vehicle used to flee the scene.

Does anyone who knew Keenan Braxton or was in that neighborhood that night have information to share with investigators?
