Boston -- A federal grand jury has returned a 30-count indictment against the surviving suspect in the Boston Marathon bombings.
Dzhokhar Tsarnaev was indicted Thursday on charges including using a weapon of mass destruction and bombing a place of public use, resulting in death.
Three people were killed and more than 260 injured in twin explosions near the finish line of the marathon.
Tsarnaev's older brother, Tamerlan Tsarnaev, was killed following a shootout with police on April 19.
Dzhokhar Tsarnaev was captured hiding in a boat. According to the indictment, he wrote messages on the inside of the boat that said, among other things, "The U.S. Government is killing our innocent civilians" and "We Muslims are one body you hurt one you hurt us all."
