Boston suspect risks death penalty

Boston Marathon bombing suspect Dzhokhar Tsarnaev was yesterday charged by federal prosecutors in his hospital room with using a weapon of mass destruction to kill — a crime that carries a possible death sentence.

Officials said Tsarnaev, 19, and his older brother set off the twin explosions at last week’s race that killed three people and wounded more than 180.

His brother, Tamerlan, 26, died on Friday after a fierce gunbattle with police.
