Carlos Arredondo, 57, (right) and his wife Melida Arredondo, 52, are seen in their front yard in Roslindale, Boston, Massachusetts, USA, on Sat., March 31, 2018. Arredondo is well known as the &quot;man in the cowboy hat&quot; who helped out in the aftermath of the Boston Marathon Bombing in 2013. Carlos is wearing a jacket that he has used to create a t-shirt design for when he runs the Boston Marathon later this year. Though he has run the race unofficially previously, this will be the first time he runs it &quot;legally,&quot; he says.<br />

Behind the couple is a memorial to their two sons,  Marine Lance Corporal Alexander Scott Arredondo and Brian Arredondo. Alex was killed while serving in Iraq in 2004, and Brian died by suicide in 2011.
