BOSTON (WHDH) — We have seen Boston Marathon victim, Jeff Bauman, a few times. He was honored at the Bruins game and at a Red Sox game. But we haven’t heard much from the man, who was the most gravely injured survivor of the Marathon bombing attacks.

Bauman was standing very close to one of the two bombs near the finish line. NBC’s Brian Williams’ spoke exclusively with Bauman at the Spaulding Rehab Hospital, where the 27-year-old continues to receive extensive therapy. He told Williams he has been touched by the generosity from complete strangers who have reached out to him with their support.

“It’s really amazing. I can’t begin to thank people enough for that. It’s really just, the letters too. I love the letters, I love reading the letters. Cause someone actually took time out of their day and thought about writing a hand-written letter to me and they just pour their heart out in this letter, and it’s amazing. You know? It just shows how great people are,” said Bauman.

He also played a critical role in the investigation. From his hospital bed, he was able to give information to authorities about the bombing suspects. He remembers seeing them and getting a funny feeling, even before the explosions.

Boston Marathon bombing suspect Dzhokhar Tsarnaev appeared in federal court Wednesday and plead not guilty to 30 counts, including using weapons of mass destruction.

Bauman will sit down for another interview along with the man who saved his life, Carlos Arredondo, on the TODAY Show on NBC Thursday morning.
