Sean Williams was 18 when he was fatally shot on the evening of June 18, 2017, on Edmondson Avenue in West Baltimore. A well-known figure in the city’s dirt bike scene and a celebrated member of the 12 O'Clock Boys, Williams—known as Biker Boy Sean—shared riding videos online and hoped to turn his passion into a professional career to support his mother. He was taken to the University of Maryland Shock Trauma Center, where he was pronounced dead.

His death drew widespread grief from the neighborhood and his online following; West Coast rapper The Game, who had featured Williams in a Baltimore music video, donated to a GoFundMe set up by Williams’s mother to help with funeral costs. Despite the public profile and attention the shooting received, the case remains unsolved and no arrests or suspects have been publicly announced. The circumstances of the killing and who was responsible are not known.

If anyone knew Sean, saw activity on Edmondson Avenue that night, or has information that could help, please share what is known with investigators.
