Transcript for Boston Bomber Breaks His Silence and Apologizes
to death. We knew he would have a moment to talk, but were unsure if he would use it. He did. Talking to the victims an their families, so many showing up to the federal courthouse, addressing tsarnaev, calling him a coward, despicable. Then tasarnaev himself with a message. ABC's Ron call boiborne from Boston. Reporter: He entered the courtroom smiling, but just moments before he was formally sentenced to death, dzhokhar tsarnaev spoke for the first time, softly and without emotion. "I am sorry for the lives I have taken, for the suffering I have caused you and for the damage I have done." Without ever turning to face the dozens of victims gathered, he confessed to his crime. "If there is any lingering doubt, I did it, along with my brother." That stunning moment, following three hours of gut-wrenching impact statements from victims like father bill Richard, seen here on that day standing with his family. Tsarnaev just a few feet away. "He chose hate. He chose destruction. He chose death. That is all on him." Richard's 8-year-old son martin was killed, his 6-year-old daughter Jane had her leg amputated. Rebekah Gregory lost her leg too. "You and your brother have lost. You unified us." In the 800 days since the bombing, tsarnaev has only been seen in that prison cell surveillance video, never taking the witness stand at trial. But today he said he heard the pain of those who testified against him. "I was listening the suffering that was and the hardship that still is." Never apologized for a thing. I wanted to know, you know, but -- I don't think it really matters. He's not sorry. If he was sorry, he would have never did that. Reporter: Tsarnaev will eventually be moved to a prison in Indiana, which is from federal death row inmates are held, until execution. Tonight, his lawyers are saying they will file an appeal of his conviction, David, that could take many years. All right, Ron Claiborne leading us off from Boston. Ron, thank you.
