The latest on the suspects in the Boston Marathon bombing, which appears to have been the work of brothers who emigrated to the U.S. from Chechyna:
Police on Friday killed one suspect in the Boston Marathon bombing during a shootout and mounted a house-to-house search for a second man in the suburb of Watertown after a bloody night of shooting and explosions in the city's streets.
A national security official identified the hunted man as Dzhokar A. Tsarnaev, 19, and said the dead suspect was his brother, Tamerlan Tsarneav, 26. The brothers had been in the United States for several years, the official said.
More background on the Tsarnaev still at large:
Born July 22, 1993, according to Williams, Tsarnaev attended Cambridge Rindge and Latin School, has a Massachusetts drivers' license and has been in the country for around a decade.
He also apparently won a 2011 scholarship from the city of Cambridge, Massachusetts.
