A US jury on Monday (July 21) found a friend of the accused Boston Marathon bomber guilty of obstructing the investigation into the deadly blasts by removing a backpack containing fireworks shells from the suspect's dorm room.

The friend, Kazakh exchange student Azamat Tazhayakov, was found guilty of conspiracy to obstruct justice and obstruction of justice for going to suspected bomber Dzhokhar Tsarnaev's room three days after the April 15, 2013 attack and removing a backpack containing empty fireworks shells.
