Boston Marathon bomber manhunt: One suspect dead, second on the run

run BOSTON—A late-night police chase and shootout has left one marathon bombing suspect dead and another on the run, police here said, as residents of the still-grieving city were ordered by officials to "shelter in place" while the manhunt continues. One police officer was killed and another was seriously wounded during the violent spree. The Associated Press identified the surviving Boston bomb suspect as Dzhokhar A. Tsarnaev, 19, of Cambridge, Mass., and said that the suspects were brothers. The second bombing suspect is Tamerlan Tsarnaev, 26, according to NBC News, who was found with an IED on his body. The brothers are of Chechen origin, according to NBC, a volatile part of Russia's North Caucasus. Photographer Johannes Hirn took this photo essay of the older brother, a boxer. The captions suggest Tsarnaev came to America as a child with his family as refugees after fleeing Chechnya for Kazakhstan.
