(CNN) -- A federal grand jury has returned a 30-count indictment against Dzhokhar Tsarnaev, the surviving suspect in the Boston Marathon bombings, the U.S. attorney's office said Thursday.
The double bombings near the finish line of the Boston Marathon on April 15 killed three people and injured at least 264.
Police took Tsarnaev into custody on April 19 after finding him hiding in a boat in the backyard of a Watertown, Massachusetts, home.
The other bombing suspect, his brother Tamerlan Tsarnaev, died after a gunfight with authorities hours before his brother's arrest. After much secrecy and protest, Tamerlan was buried in a rural Virginia cemetery.
