A prosecutor has told a jury in the federal trial of a friend of Boston Marathon bombing suspect Dzhokhar Tsarnaev that the case is about someone who lied, "not about someone who didn't remember."

Robel Phillipos 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. Two bombs placed near the marathon finish line killed three people and injured more than 260.

During closing arguments Tuesday, Assistant U.S. Attorney Stephanie Siegmann said Phillipos repeatedly lied about what he did the night of April 18, 2013, during interviews with FBI agents.

Phillipos' lawyers have told jurors he was too high on marijuana to remember what he did.
