Not guilty, says Boston bombing suspect

His arm in a cast, Boston Marathon bombing suspect Dzhokhar Tsarnaev pleaded not guilty to terrorism charges yesterday in his first courtroom appearance since his capture at the end of a chaotic week in April.

Tsarnaev, 19, smiled crookedly — he appeared to have a jaw injury — at his sisters in court as he arrived.

Then, after he leaned over toward a microphone and said, “Not guilty” over and over in a Russian accent, he was led out of the courtroom, making a kissing motion toward his family as he left.
