Indicted Boston Marathon bomber may face death penalty

Surviving Boston Marathon bombing suspect Dzhokhar Tsarnaev has been indicted on 30 counts, including detonating a weapon of mass destruction resulting in deaths, in the United States.

Tsarnaev downloaded bomb-making instructions from an al Qaeda magazine, gathered online material on Islamic jihad and martyrdom.

He also scribbled anti-American messages inside the boat where he was found wounded after the bombings, a federal indictment charged on Thursday.

According to CBS News, the indictment contains the bombing charges, punishable by the death penalty, that were brought against the 19-year-old in April.

Prosecutors have also added charges covering the slaying of an MIT police officer and the carjacking of a motorist during the getaway attempt that left Tsarnaev's older brother, Tamerlan, dead.

Three people were killed and more than 260 wounded by the two pressure-cooker bombs that went off near the finish line of the marathon on April 15.

Tsarnaev was arrested four days later, hiding in a boat parked in a backyard in Massachusetts.
