On the early evening of June 10, 2015, 16-year-old Jonathan Dos Santos was riding his bicycle on Fuller Street in Dorchester when he was ambushed and shot. He collapsed a short distance away and was taken to Boston Medical Center, where he was pronounced dead.

Surveillance video and investigation reportedly showed two people lying in wait at the intersection of Washington and Fuller streets; footage allegedly captured them pacing, talking and laughing before one stood and fired multiple shots, at least one striking Jonathan in the neck. Within days two teenagers were arrested: 16-year-old Dushawn Taylor-Gennis and 14-year-old Raeshawn Moody. Both were charged as adults with murder and unlawful possession of a firearm, pleaded not guilty at arraignment, and were ordered held without bail. Authorities said witnesses and video helped identify the suspects, and the suspects surrendering was aided by their mothers.

Investigators reportedly believe the motive was Jonathan’s refusal to join a gang; he had told a basketball coach he felt pressured and was afraid to go to school. Did anyone who knew Jonathan or saw activity around Washington and Fuller streets that evening come forward with information?
