The Costa Rican immigrant used his clothes and towels to stop the victims from bleeding.
Hailed by the local media as a hero, Arredondo helped one victim, who lost both his legs and was drenched in blood, into a wheelchair that the marathon medical staff had brought, and he says, he kept talking to the man so he wouldn't lose consciousness.
‘I kept talking to him. I kept saying, “Stay with me, stay with me,”' Arredondo, who is a member of the Red Cross disaster team, told Maine Today.
