During the trial Monday of the friend of alleged Boston Marathon bomber Dzokhar Tsarnaev, the defense told the jury that Robel Phillipos had smoked marijuana and was in an altered state of mind the day he allegedly went to Mr. Tsarnaev's college dorm room and was involved in the removal of incriminating evidence in the days following the Boston attack.
