For these Boston Marathon bombing survivors, the road to healing meant helping others

Ten years after the Boston Marathon bombing killed three and injured hundreds, those who survived the day are still healing. 

Paul Norden and Jacqui Webb were among the thousands watching, standing with friends. Webb told CBS News that she remembered the first moments of the attack.

"We were waiting for our friend to run by and we heard the first blast go off," Webbs said. "You saw what was a mushroom cloud. I turned to start going towards the street, and I remember the barricade being there and thinking like, 'How am I going to hop that?' And that's when the second blast went off."
