Article Photos: Stories of the wounded in Boston Marathon bombing 3/4

ADDS NAME OF VICTIM - FILE - In this April 15, 2013 file photo, Sydney Corcoran, of Lowell, Mass. is tended to at the finish line of the Boston Marathon after two bombs exploded, in Boston. As people lay badly bleeding in the smoke of the Boston Marathon bombings, rescuers immediately turned to a millennia-old medical device to save their lives _ the tourniquet. Using belts, shirts and other materials, they tied off bleeding limbs in fast-acting bids to prevent major blood loss, shock and death. Such fast work no doubt saved many lives, doctors at Boston area hospitals said. (AP Photo/The Boston Globe,  John Tlumacki) MANDATORY CREDIT, BOSTON HERALD OUT, QUINCY OUT, MAGS OUT, NO SALES.
