Looking back at three that helped rescued an injured man at the Boston Bombings

Almost two years, ago two bombs exploded near the marathon's finish line on April 15, 2013, killing three people and wounding more than 260.

But moments after those bombs exploded, three people helped rescue a man whose legs were blown off. That man, Jeff Bauman, was considered a hero himself when he gave authorities a description that helped them locate the suspects.
