Marcos Medina was 16 when he was fatally shot during an argument on the evening of September 30, 2009, in the 5300 block of 56th Avenue in Riverdale, Maryland. The neighborhood is described as predominantly Latino and immigrant; the dispute escalated to gunfire and left Marcos dead. A 17-year-old was also hit in the same exchange and was taken to a hospital and later released after treatment.

A makeshift shrine appeared at the scene in the days after the killing as friends and family mourned.

If anyone witnessed the shooting or has information about what led to that evening’s violence, please come forward.
