Marc Fucarile, the last Boston Marathon survivor to leave hospital after the twin bombings, has told ITV News his fiancee and son Gavin were "the reason I fought to live",
"That little boy is my life ... I just couldn't think about not being with them," Mr Fucarile, who will marry his fiancee Jennifer Regan later this week, said.
"I wasn't going to let him grow up without a dad, I was going to fight no matter what," he added.
Mr Fucarile and his family created their own crowd funding website, Help Marc Fucarile, which has generated more than $190,000 (£113,700) so far.
