Dzhohkar Tsarnaev

Boston Marathon bomber Dzhohkar Tsarnaev was sentenced to death on Friday. But his execution may not happen for decades - if ever.

US intelligence agencies added the mother of the Boston bombing suspects to a government terrorism database 18 months before the bombings, two officials told The Associated Press. She called it "lies and hypocrisy" and said she has never been linked to crimes or terrorism.
