Dzhokhar Tsarnaev, the remaining suspect in the Boston Marathon bombings assured his parents in a phone conversation that he and his slain brother were innocent, his mother Zubeidat Tsarnaeva told the Associated Press.

Three college friends of Boston Marathon bombing suspect Dzhokhar Tsarnaev are under arrest, suspected of removing items from his dorm room after the April 15 attack. Two of them were detained on April 20 on immigration charges and a third has been taken into custody, sources said.

The surviving Boston Marathon bombings' suspect Dzhokar Tsarnaev has been transferred from Beth Israel Deaconess Medical Center and taken to the Federal Medical Center Devens about 40 miles west of Boston, the Guardian reported. The facility treats federal prisoners and detainees who require specialized long-term medical or mental health care.
