Carlos Arredondo, aka The Man in the Cowboy Hat, is best known for saving a life during the Boston Marathon bombing, but the story begins with the death of his own son, Alex, in the Iraq War. In 2004, three Marines came to Carlos’s house to inform him that his oldest son, Alex, had died in Iraq. Carlos’s extreme grief over Alex’s death launched him on a journey to honor his son and fight for the America he believed in. Publicly Carlos had a new purpose. Behind the scenes the story was more complex.
