Robert Stahl, attorney for Dias Kadyrbayev, a college friend of Boston Marathon bombing suspect Dzhokhar Tsarnaev, leaves federal court after a hearing for his client Tuesday, May 13, 2014, in Boston. Kadyrbayev and fellow Kazakhstan national Azamat Tazhayakov are charged with tampering with evidence for removing Tsarnaev's laptop and a backpack containing fireworks from his college dorm room shortly after last year's fatal bombing. Judge Douglas Woodlock ruled Tuesday the men will be tried separately, but their trials do not need to be moved out of Massachusetts. (AP Photo/Stephan Savoia)

FILE - This file photo by the Federal Bureau of Investigation shows Dzhokhar Tsarnaev, surviving suspect in the Boston Marathon bombings who is accused in two bombings that killed three people and injured more than 260 others near the finish line of the April 15 marathon. Lawyers for Boston Marathon bombing suspect Dzhokhar Tsarnaev argued Wednesday, May 7, 2014, that statements he made to authorities after he was arrested should be thrown out because he was questioned for 36 hours in a hospital room while suffering from gunshot wounds and without being told his rights.
