FILE - In this April 15, 2013 file photo, emergency workers aid an injured woman on Boylston Street, at the site where a bomb exploded during the 2013 Boston Marathon in front of the Marathon Sports store in Boston. Shattered glass lies on the sidewalk in the background. In the course of a year, limbs have been replaced, psyches soothed, the wounds sustained in a moment at the marathon’s finish line have at least begun to heal. At the same time, a city shaken by an act of terrorism has returned to its usual rhythms - sadder, but some say stronger, as well. (AP Photo/Charles Krupa, File) less
