Dzhokhar Tsarnaev's (joh-HAHR' tsahr-NEYE'-ehvz) college roommate has testified that the Boston Marathon bombing suspect didn't seem agitated or nervous in the days after the deadly attack.

Andrew Dwinells testified Tuesday about Tsarnaev's mood when he saw him in their room at the University of Massachusetts-Dartmouth in the few days after the April 2013 bombing. Dwinells said Tsarnaev slept a little bit more than usual but otherwise behaved the same way he always did.

Dwinells' testimony came during the trial of Azamat Tazhayakov (AZ'-maht tuh-ZAY'-uh-kahv), a Tsarnaev friend who is accused with another friend of removing items from Tsarnaev's dorm room three days after the bombings and hours after the FBI posted video and photos of Tsarnaev as a suspect.

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