A U.S. grand jury has indicted Boston Marathon bombing suspect Dzhokhar Tsarnaev on 30 charges, including use of a weapon of mass destruction in the twin explosions near the finish line of the April 15 race.
The 19-year-old Tsarnaev was charged Thursday and, if convicted, faces the death penalty or life imprisonment.
Three people were killed and more than 260 injured in the blasts, and Tsarnaev is also accused in the killing of a policeman a few days after the bombings. At the time, Tsarnaev and his older brother, Tamerlan, were attempting to flee authorities after security camera footage of them walking along the path of the marathon shortly before the explosions was broadcast nationwide.
Tamerlan Tsarnaev died after a shootout with police, while Dzhokhar was arrested a day later while hiding in a boat parked in the backyard of a home in a Boston suburb.
The Tsarnaev brothers spent much of the last decade living in the U.S.
But they had roots in the restive Russian regions of Chechnya and Dagestan, where Islamic extremists often attack Russian authorities. Law enforcement officials say that Dzhokhar Tsarnaev wrote several messages on the inside of the boat, including one saying, "The U.S. government is killing our innocent civilians," and another saying that "We Muslims are one body, you hurt one, you hurt us all."
