FILE - In this Monday, April 15, 2013 file photo, Boston Firefighter James Plourde carries an injured girl away from the scene after a bombing near the finish line of the Boston Marathon in Boston.

Such fast work no doubt saved many lives, doctors at Boston area hospitals said. (AP Photo/MetroWest Daily News, Ken McGagh, File) MANDATORY CREDIT less
