BOSTON (AP) — Boston Marathon bombing suspect Dzhokhar Tsarnaev was charged in his hospital room Monday with using a weapon of mass destruction to kill, and he could face the death penalty if convicted.

Tsarnaev, 19, was accused by federal prosecutors of joining with his older brother to set off the two pressure-cooker bombs that sprayed shrapnel into the crowd at the finish line last Monday, killing three people and wounding more than 180.
