BOSTON (AP) — Jurors in the federal trial of a friend of Boston Marathon bombing suspect Dzhokhar Tsarnaev have ended a fifth day of deliberations without reaching a verdict.

Robel Phillipos is accused of lying about being in Tsarnaev’s dorm room three days after the deadly bombing, when two other friends removed a backpack containing fireworks and other potential evidence.

Phillipos’ lawyers say he couldn’t clearly remember what happened because he had smoked marijuana heavily that day.

Jurors went home for the day Monday. They return Tuesday. Since they began Oct. 21, they have spent more than 33 hours deliberating.
