The teenager who allegedly helped detonate two bombs at the finish line of this year's Boston Marathon, killing three people and injuring more than 260, pleaded not guilty to terrorism charges during a brief court appearance Wednesday.
Dzhokhar Tsarnaev, 19, who faces 30 counts, including murder and the use of a weapon of mass destruction resulting in death, made his first public appearance since his arrest April 19.
Dressed in an orange prison jumpsuit and restrained by handcuffs as he entered and left a federal courtroom in Boston, Tsarnaev spoke with a Russian accent as he repeatedly said "not guilty" into a microphone.
