FILE - In this April 15, 2013 file photo, an emergency responder and volunteers, including Carlos Arredondo, in the cowboy hat, push Jeff Bauman in a wheel chair after he was injured in an explosion near the finish line of the Boston Marathon. At least three people were killed, including an 8-year-old boy, and more than 170 were wounded when two bombs blew up seconds apart. Virtually overnight, Arredondo, a peace activist and sometime cabbie taxi and truck driver, has turned into a living reminder of both the horror and bravery witnessed in Monday’s double bombing at the finish line of the race.
