MARATHON BOMBER SUES PRISON

Boston Marathon bomber Dzhokhar Tsarnaev has filed a lawsuit over his treatment at a supermax prison.

The hand-written complaint, originally filed in January, was amended March 5. Among other things, Tsarnaev claims the defendants – which include BOP, the company that administers the prison and Attorney General Merrick Garland – are interfering with his ability to communicate with his family, placing a hold on his money and hurting his chances of avoiding a death sentence.
