US: Boston suspect downloaded bomb instructions

Boston Marathon bombing suspect Dzhokhar Tsarnaev downloaded bomb-making instructions from an al-Qaeda magazine, gathered online material on Islamic jihad and martyrdom and later scrawled anti-American messages inside the boat where he lay wounded, a federal indictment charged Thursday.

The 30-count indictment contains the bombing charges, punishable by the death penalty, that were brought in April against the 19-year-old Tsarnaev, including use of a weapon of mass destruction to kill. (AP)
