UPDATE: What We Know About the Boston Bombings - 2 Suspects, 1 Dead, 1 Captured

UPDATE, 9:00pm ET, April 19: Boston Police report they have captured the second suspect identified in the Boston Marathon bombings, Dzhokhar A. Tsarnaev, 19. The suspect was taken alive from a private residence at 67 Franklin St. in Watertown, MA, where he was believed to be hiding inside a dry docked boat in the backyard. 


One of the suspects in the Boston Marathon bombing is dead and the other is on the run after leading police in a deadly, sprawling chase that included extensive gunfire and use of explosives and left one police officer dead and another seriously injured early Friday.

Part of the greater Boston area is on lockdown while police undergo a massive manhunt for the second suspect. Authorities are urging residents to stay indoors and have suspended public transportation and closed schools and the airspace over Watertown, Mass.

Law enforcement officials identified the suspects as Tamerlan Tsarnaev, 26, who was killed during shootout with police, and Dzhokhar A. Tsarnaev, 19, who remains at large. Officials say they are brothers from Chechnya, a mostly Muslim Russian territory that fought two wars against Russia in the 1990s.

The chase began after 10 p.m. on Thursday, when police received a call that two men robbed a 7/11 in Cambridge, which neighbors Boston, with a security camera capturing an image of a man identified as one of the suspects. Officials say shortly afterward, a Massachusetts Institute of Technology police officer was shot and killed in his patrol car. Police believe the two suspects are responsible.
