The surviving Boston Marathon bombing suspect has stopped talking to authorities, after a representative of the U.S. Attorney's Office entered his hospital room and advised him of his Miranda rights, reports the Associated Press.
Dzhokhar Tsarnaev, 19, initially told interrogators he and brother Tamerlan, 26, became radicalized Muslims and detonated the bombs as a result of U.S. military involvement in Iraq and Afghanistan.
Members of an FBI special interrogation team for high-value suspects initially invoked the public safety exemption in declining not to Mirandize Dzhokhar. The American Civil Liberties Union immediately questioned that decision.
