BOSTON (AP) -- Lawyers for three friends of Boston Marathon suspect Dzhokhar Tsarnaev are headed to court to update a judge on evidence turned over by prosecutors.
The pretrial conference is scheduled for Monday morning.
Two of the men are charged with removing a laptop and a backpack containing fireworks from Tsarnaev's University of Massachusetts Dartmouth dorm room several days after the bombing.
A third man is accused of lying to investigators about visiting Tsarnaev's dorm room.
All have pleaded not guilty. Trial is scheduled for June 23.
Tsarnaev has pleaded not guilty to a variety of the charged stemming from the April 15 attack that killed three and injured more than 260.
