In the pre-dawn hours of August 12, 2023, 16-year-old Robert Isiah Walker was shot inside a gas station in the 9800 block of Piscataway Road in Clinton, Maryland. Police arrived about 2:40 a.m. and found Robert suffering from gunshot wounds; he was pronounced dead at the scene.

Prince George’s County homicide detectives led the investigation and said early on they did not believe the shooting was random. A reward of up to $25,000 was offered for information leading to an arrest and indictment. In August 2025 authorities announced an arrest: 18-year-old Stephon Johnson of District Heights, who was a juvenile at the time of the shooting, was charged as an adult with first- and second-degree murder and other related counts and held without bond. The motive remains under investigation.

If anyone has information about Robert, the events that night, or the people involved, please contact investigators.
