Damion Blocker was 14 when he was killed on January 19, 1996, after school at the Winston Education Center in Southeast Washington, D.C. He had gone there to pick up his 5-year-old cousin and was a familiar face at the school, once a student and often visiting teachers.

Two teenagers, 18-year-old Darrick Evans and William Arnell Batchelor Jr., were pursuing a 16-year-old rival. Batchelor stayed outside while Evans, armed and wearing a ski mask, entered the building and continued the pursuit. In a stairwell, a bullet intended for the rival grazed that teenager’s arm but struck Damion in the right shoulder, passing through both lungs and his heart. The community reacted with increased security at the school and widespread outrage; about 1,500 people attended Damion’s funeral, including Mayor Marion Barry.

Darrick Evans was convicted of first-degree murder after a jury rejected his defense that the shot was fired accidentally while uncocking the gun. William Arnell Batchelor Jr. cooperated with prosecutors, pleaded guilty to involuntary manslaughter, and received probation. Does anyone have information about Damion, his family, or witnesses who were at the school that afternoon?
