Bomb suspects' friends arrested - May 2nd, 2013 - National

— The FBI says three college friends of the Boston Marathon bombing suspect have told agents they suspected Dzhokhar Tsarnaev was one of the bombers only after authorities released photos of him and his brother.

In FBI interviews recounted in court papers, the young men said the photos prompted an exchange of text messages that led them to try to get rid of Tsarnaev's backpack and his laptop. The three are now facing charges.
