Cowboy hat hero at Boston Marathon remembers bombing

Carlos Arredondo is one of the most identifiable faces of the Boston Marathon bombings.

He's the man in the cowboy hat who saved a stranger.

"There's no day that goes by that I don't think about it. It was very dramatic and horrifying event. I was very scared when this happened. I did what I could," he said.

Arredondo was at the marathon with groups honoring his sons, one who was killed in Iraq, the other who committed suicide.

Arredondo had been handing out American flags when the bombs went off.

NBC 10's Brian Crandall met Arredondo two hours after the deadly blasts. His clothes were stained with blood as was a flag he held.

"We started putting pieces of clothing on people's legs, a lot of bleeding, limbs all over the sidewalk. It's very sad. Very sad," Arredondo said.

Arredondo helped save Jeff Bauman, whose legs were severed.

"Myself and others, that's what we did, we put him together, and get him out of there real quick," he said.

When asked if he thinks about the day he helped save someone's life, Arredondo said he has nightmares of seeing himself running with a wheelchair and Bauman on it.

Arredondo and Bauman are now forever linked. And Arredondo still has the blood-stained flag he had with him on the day of the bombing.

"When I was leaving with Jeff, I saw the flag, I break the stick, I roll it into my pocket and I put it there," he said.

Arredondo plans to be back at the finish line for the 2014 Boston Marathon handing out American flags. He'll be joined by others who shared last year's pain.

"We're going to try to support each other when the time comes, the exact time that that happened.{} Hopefully we'll be Boston strong," he said.
