Two suspects in the Boston Marathon bombing were identified by the Federal Bureau of Investigation as brothers Tamerlan Tsarnaev, 26, and Dzhokhar Tsarnaev, 19, who moved to the U.S. after briefly living in Chechnya. Both brothers were legal residents.
Tamerlan was shot early Friday morning and Dzhokhar remains at large. An ongoing manhunt has Boston on lockdown, with one MIT police officer dead.
