The two suspects in the Boston Marathon bombing killed an MIT police officer and hurled explosives at police in a car chase and gun battle overnight that left one of them dead and his brother on the loose, authorities said Friday as thousands of officers swarmed the streets in a manhunt that all but paralyzed the Boston area. The suspects were identified by law enforcement officials and family members as Dzhokhar (pictured in AP photo) and Tamerlan Tsarnaev, brothers from a Russian region near Chechnya, which has been plagued by an Islamic insurgency that has carried out deadly bombings. They lived near Boston and had been in the U.S. for about a decade, an uncle said. Tamerlan Tsarnaev, a 26-year-old who had been known to the FBI as Suspect No. 1 and was seen in surveillance footage in a black baseball cap, was killed overnight, officials said. His 19-year-old brother — dubbed Suspect No. 2 and seen wearing a white, backward baseball cap in the images from Monday’s deadly bombing at the marathon finish line — escaped/AP. More here.
