Two of Dzhokhar Tsarnaev's friends have pleaded not guilty to helping the Boston Marathon bomber hide the evidence of his crime. At a federal court in Boston, Friday, Dias Kadyrbayev, pleaded not guilty to obstruction of justice—a charge for which he faces up to 25 years in prison or deportation—while Robel Phillipos, facing up to 16 years, pleaded not guilty to lying to investigators. Kadyrbayev, Phillipos and a third friend--whose court appearance was postponed until later Friday—are all charged with disposing of Tsarnaev's laptop and backpack filled with empty fireworks shells three days after the bombing. After the hearing, Kadyrbayev's lawyer Robert Stahl told reporters that his client had no idea what Tsarnaev had done when he went to his friend's dorm room. "There was no criminal intent from him to help Dzhokhar, no obstruction of justice in any way," Stahl said.
