Boston Marathon bombing suspect pleads not guilty

Boston Marathon bombing suspect Dzhokhar Tsarnaev has pleaded not guilty to 30 counts including use of a weapon of mass destruction to kill.

He entered the plea Wednesday in federal court in Boston. For first one, he leaned toward a microphone and said, "Not guilty," in a Russian accent. He then said not guilty repeatedly about a half-dozen more times. Federal prosecutors are weighing whether to pursue the death penalty for the 19-year-old Tsarnaev. (Reuters)
