BOSTON (CNN) -

A federal jury on Monday found a friend of Boston Marathon bombing suspect Dzhokhar Tsarnaev guilty of obstructing the investigation into the 2013 attack.

The jury found Azamat Tazhayakov guilty of obstructing justice and conspiring to obstruct justice relating to the removal of a backpack from Tsarnaev's dorm room after the bombings.

But the jury also found Tazhayakov not guilty on two charges relating to allegations that he removed a laptop from the same room.

The verdict came in the first trial related to the April 15, 2013, bombings that killed three people and injured more than 200 others.
