Dzokhar Tsarnaev, the 19-year-old suspect in the Boston marathon bombings pleaded not guilty to all charges in his first court appearance.
Prosecutors could press for the death penalty for 17 counts within the 30 counts of using a weapon of mass destruction, the killing of a university police officer, carjacking and downloading internet material from Islamist radicals.
Tsarnaev's older brother and fellow suspect Tamerlan was killed days after the attack during a large-scale police operation.
