After the explosions at the Boston Marathon on Monday April 15, Twitter became a primary source of breaking news, and also of misinformation . Conversations were curated around the hashtags #bostonmarathon  and #bostonexplosions  the first days. On Thursday night, one of the suspects, Tamerlan Tsarnaev, 26, was killed during a police persecution in Cambridge, and the city of Boston and close communities were on lockdown on Friday during the search (#manhunt ) of Tamerlan's younger brother, Dzhokhar Tsarnaev, 19. Dzhokhar was found wounded Friday evening in Watertown (#watertown ). A debate has ensued after it was announced that he will be questioned without being Mirandized  (#mirandarights ). Many are also worried about how this will affect immigrants  in the U.S. due to the Chechen ethnic origin  of the Tsarnaev brothers.
