			 Robel Phillipos, 21, was too intoxicated by marijuana the night of 
			April 18, 2013, when he is charged with accompanying two other men 
			to the accused bomber's college dorm room, to remember his actions, 
			his lawyers assert. 
 They contend that his confession to the FBI days later of going to 
			suspected bomber Dzhokhar Tsarnaev's room with two other friends who 
			removed a backpack containing empty firework shells did not reflect 
			his actual memories of that evening but rather what FBI agents told 
			him happened.
 
 After prosecutors rested their case in U.S. District Court in Boston 
			on Wednesday, defense attorneys began by questioning a college 
			friend and high school friend of Phillipos, a resident of Cambridge, 
			Massachusetts, about his marijuana use.
   
			
			 Defense attorneys are also expected to call expert witnesses on how 
			marijuana affects the brain.
 Federal prosecutors contend that Phillipos, and two other friends of 
			accused bomber Dzhokhar Tsarnaev, went to the suspect's dorm room 
			three days after the attack that killed three people and injured 
			more than 260, shortly after the FBI released photos of the 
			suspected bombers.
 
 One of the Kazakhs, Azamat Tazhayakov, was convicted in July of 
			obstruction of justice for taking the backpack. The other, Dias 
			Kadyrbayev, pleaded guilty to obstruction in August.

			Phillipos, who faces the less serious charge of lying to 
			investigators, could be sentenced to up to 16 years in prison if 
			convicted.
 Tsarnaev, 21, is awaiting trial on charges that carry the death 
			penalty.
