Comment on Jury to decide if Tsarnaev friend was a liar or high

BOSTON — A friend of Boston Marathon bombing suspect Dzhokhar Tsarnaev told a string of lies to investigators, a prosecutor told a jury Tuesday, but a defense lawyer said the defendant was a frightened 19-year-old who couldn’t remember certain details because he had smoked marijuana for at least 12 hours straight. Robel Phillipos, of Cambridge, is charged with lying to the FBI about being in Tsarnaev’s dorm room at the University of Massachusetts-Dartmouth while two other friends removed a backpack containing fireworks and other potential evidence several days after the April 15, 2013, attack.
