The jury is deliberating for a second full day in the trial of Robel Phillipos, a friend of Boston Marathon bombing suspect Dzhokhar Tsarnaev.

Phillipos is accused of lying to FBI agents who interrogated him five times in the days after the bombings.

Phillipos, 21, his mother, relatives and friends are waiting in the courthouse cafeteria. They look tired but calm.

Upstairs, 12 jurors are deciding whether Phillipos knowingly tried to deceive FBI agents who were investigating the Boston Marathon Bombings. He signed an FBI statement that he entered Tsarnaev’s dorm room at the University of Massachusetts Dartmouth with two friends after photos of the bombing suspects were released.

Federal prosecutors are not accusing Phillipos of tampering with evidence, but of watching friends remove a backpack from Tsarnaev’s dorm room. But Phillipos’ lawyer says his client was high on marijuana in the days after the bombings and when he spoke to FBI agents. As of 1 p.m., the jury has not asked any questions today.
