Rodney Christopher Chase, 59, was a homeless drug addict who became sober last year with the help of the Salvation Army and the Violence Intervention Program at the Maryland Shock Trauma Center. He was featured this past fall in The Baltimore Sun's three-part series on gun homicides, "Shoot to Kill," in which he talked about the viciousness of Baltimore's streets and bullets from high-caliber guns that he had somehow dodged for more than four decades.
