Three new suspects have were charged in connection with the Boston Marathon bombings Wednesday for interfering with the police investigation of the attacks. The suspects allegedly destroyed and concealed Dzhokhar Tsarnaev’s backpack and laptop after the bombing. Two of the suspects, Azamat Tazhayakov and Dias Kadyrbayev, are reportedly from Kazakhstan and went to school with Dzhokhar at UMass Dartmouth. The two reportedly have been held in a county jail for more than a week on allegations that they violated their student visas. The Boston Globe identified the third man as Robel Phillipos, 19, of Cambridge, and he reportedly is a U.S. citizen. According to ABC News, the backpack the suspects removed was in Dzhokhar’s dorm room and contained fireworks.
