Three college friends of Boston Marathon bombing suspect Dzhokhar Tsarnaev were arrested and accused Wednesday of removing a backpack containing fireworks emptied of gunpowder from Tsarnaev's dorm room three days after the attack to try to keep him from getting into trouble.
Azamat Tazhayakov and Dias Kadyrbayev were charged with conspiring to obstruct justice. A third man, Robel Phillipos, was charged with lying to investigators about the visit to Tsarnaev's room.
