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.
A Boston Marathon bombings survivor has told ITV News those responsible for the attacks should be handed the death penalty.
Marc Fucarile, who lost his right leg above the knee and broke his spine, Washington Correspondent Robert Moore: "You know they're sick, sick people. They killed people that didn't do anything to them and I think they should pay the ultimate sacrifice.
"I think that anyone that thinks in that direction should also pay the sacrifice".
Tamerlan Tsarnaev, who died in a shoot-out with police four days after the attacks, and his brother Dzhokhar have been accused of carrying out the Boston Marathon bombings.
Dzhokhar Tsarnaev has pleaded not guilty to 30 charges.
A Boston Marathon bombings survivor has told ITV News he feels "unbelievably lucky" to be alive.
Marc Fucarile, who spent 100 days in hospital following the blasts last year, told Washington Correspondent Robert Moore: "I looked at a picture - right next to me there was a piece of metal fencing ... bent at a 90 degree angle around the mailbox."
Mr Fucarile said the fact he was still here with just one leg missing "is amazing."
"I have no idea how I can still talk, think, walk ... I'm definitely lucky," he added.
Information that may have raised US scrutiny of Boston Marathon bombing suspect Tamerlan Tsarnaev fell through the cracks in communications among US intelligence agencies and between the United States and Russia, an inspectors general report released today showed.
US intelligence was alerted by Russian intelligence in 2011 that Tsarnaev might pose a threat, but lack of further information led to less heightened awareness of the danger he posed, said the report by inspectors general for the US intelligence community.
Two Chechen brothers, Tamerlan and his younger brother Dzhokhar, are suspected of planting pressure-cooker bombs near the race's finish line last April 15 in an attack that killed three people and wounded more than 260.
Tamerlan died after a gunfight with police while the younger brother is awaiting trial on charges that could lead to the death penalty if he is convicted.
US prosecutors will seek the death penalty for Boston Marathan bombing suspect Dzhokhar Tsarnaev, Attorney General Eric Holder said in a statement today.
"The nature of the conduct at issue and the resultant harm compel this decision," Holder said.
Prosecutors say that Tsarnaev, 20, and his brother Tamerlan, 26, planted a pair of homemade pressure-cooker bombs at the race's crowded finish line on 15th April 2013, killing three people and wounding 264.
Three nights later, the pair killed a university police officer and later engaged in a shootout with police that left Tamerlan dead, it is alleged.
Convicted mobster James 'Whitey' Bulger has been sentenced to two life terms plus five years in prison after being found guilty of gangland crimes including 11 murders.
District Judge Denise Casper told Bulger, now 84: "The scope, the callousness, the depravity of your crimes are almost unfathomable.
"Your crimes are made all the more heinous because they are all about money."
More than $122,000 (£76,030) has been raised for a homeless man who handed a backpack stuffed with cash that he found to police.Read the full story ›
A police photographer who documented the unfolding drama of the hunt and capture of Boston bombing suspect Dzhokhar Tsarnaev has released a full set of images to Boston Magazine.
Boston Magazine has now published around 50 of the striking photographs taken by Sergeant Murphy, who was suspended and then moved to nightshifts as an apparent punishment.
James 'Whitey' Bulger, once the most feared mobster in Boston who was found guilty today of 31 out of the 32 criminal charges he faced including 11 killings, was the inspiration for Jack Nicholson's character in The Departed.
The Martin Scorsese film, which also starred Matt Damon, Leonardo DiCaprio, Mark Wahlberg and Ray Winstone, won four Oscars including Best Picture and Best Director.
The plot centres around the police waging war on an Irish-American Boston gang which is headed by Frank Costello (Jack Nicholson).
