The man who was carjacked by Tamerlan and Dzhokhar Tsarnaev says he doesn't know why the two suspected Boston Marathon bombers didn't kill him.

In an interview with Today's Matt Lauer, the victim, who used the name "Danny" to protect his identity, opened up about the harrowing night that ended with a police firefight that killed Tamerlan and wounded Dzokhar. When asked why he believes he wasn't killed, Danny simply said he didn't know.
