The charges, including the shooting death of a police officer, could bring the death penalty.
Dzhokhar Tsarnaev was charged on Thursday with killing three people in the Boston Marathon bombings and fatally shooting a police officer in a federal indictment that alleged that he downloaded instructions on building a homemade bomb from an al-Qaeda website.
The 56-page indictment also said that Dzhkokhar contributed to the death of his 27-year-old brother, Tamerlan when he drove over him while trying to escape a confrontation with police three days after the April 15 bombings..
The 19-year-old Cambridge, Mass., student is also charged with using a weapon of mass destruction resulting in death and the use of a firearm resulting in death.
Tsarnaev, who faces a possible death sentence if convicted, is scheduled to be arraigned July 10.
