Early morning hours, April 19 -- The two suspects allegedly hijacked a car at gunpoint in Cambridge, Massachusetts, taking the driver as a hostage, then releasing the hostage. Officers began to chase, the suspects threw explosives and fired shots at the officers. Officers fired back, striking and killing a man, who was later identified as one of the bombers, Tamerlan Tsarnaev, 26. Another policeman, transit officer Richard H. Donohue Jr., was also shot, but survived.
