Carlos Arredondo heroically jumped into action after the bombs exploded near the Boston Marathon finish line. Trained by the Red Cross, Arredondo says he tried to stop a severely wounded victim from bleeding. Jeff Bauman survived, but later had both legs amputated.
Arredondo made headlines years ago under very different circumstances. One of his sons, a 20-year-old Marine named Alexander, was killed in Iraq by a sniper in 2004. Arredondo received the devastating news on his birthday. Distraught, the grieving father set a van on fire and suffered serious burns.
He later created a tribute to his son on his car and drove to other military families in mourning to provide comfort. Tragically, his other son took his own life in 2011.
Arredondo was at the marathon, American flag in hand, to cheer for runners competing in memory of fallen soldiers, including his son. In an interview with Anderson Cooper, he describes what he witnessed in the aftermath of the attack and why he didn't hesitate to act.
