young Police officer killed last night was Sean Collier, 26, of Somerville. His picture: https://twitter.com/ABC/status/325244154231783424/photo/1
Tsarnaev, 19, who has now been on the run from authorities for more than 10 hours, is believed to be armed with an assault-style rifle and an assortment of other weapons, including bombs, a senior federal law enforcement official said. Tsarnaev's brother, whose name has not been released, was killed after he and his brother exchanged gunfire with police officers early today, police said. Multiple explosive devices were detonated during the firefight. Officials at Beth Israel Hospital reported they received one patient who later died, but would not confirm it was the first suspect. That patient came in under guard and had suffered blast, shrapnel and so many gunshot wounds that caregivers were "unable to count" them. One police officer was also injured in the firefight and is in critical condition at a hospital. Authorities said the suspects were also responsible for the death of an MIT police officer Thursday night. Citing to the skill with which the suspects engaged police, federal law enforcement sources said they believe the men likely had paramilitary training.
