On Sunday, July 9, 2023, 30-year-old Charles Sullivan was shot inside the Circle Seven Express convenience store in the 700 block of Kenilworth Avenue NE in Northeast Washington, D.C. Officers from the Metropolitan Police Department’s Sixth District heard the shots and entered the store; Sullivan was found with multiple gunshot wounds and D.C. Fire and Emergency Medical Services pronounced him dead at the scene. An officer reported seeing someone flee carrying what appeared to be a rifle.

Investigators identified a suspect and on July 21, 2023, 18-year-old Antwain Ulmer of Cheverly, Maryland, was arrested by members of the FBI Safe Streets Cross Border Task Force and the Capital Area Regional Fugitive Task Force and charged with First Degree Murder while Armed. A grand jury later returned an indictment charging first-degree murder while armed, assault with intent to kill while armed, and related firearm offenses; the indictment also alleges a shot nearly struck another shopper in the store. Defense counsel suggested a possible self-defense claim during a January 10, 2025, hearing.

If anyone witnessed the shooting or was in the store that night, can you provide information to the investigation?
