Local residents attend a candlelight vigil in the Dorchester neighborhood of Boston, Massachusetts on April 16 where eight-year-old Boston Marathon explosion victim Martin Richard lived. A Little League baseball player, Martin lived in the blue Victorian house in working-class Dorchester - a Boston neighborhood dotted with "Kids at Play" traffic signs and budding trees - with his parents Bill and Denise, sister Jane, 7, and brother Henry, 10. Bill Richard told the world in an email on Tuesday that his son had been killed when bombs exploded at the marathon finish line. Martin's mother and sister were seriously injured. Reuters/Brian Snyder
