Boston Gripped by High-Stakes Manhunt
The Boston area remained on lockdown into the afternoon Friday as authorities conducted a manhunt for one of two brothers of Chechen background suspected in Monday's Boston Marathon bombings and a deadly showdown that began unfolding Thursday night.
Authorities identified one suspect as 26-year-old Tamerlan Tsarnaev, who was killed in a confrontation with police in Watertown, Mass., according to a U.S. law-enforcement official.
A manhunt was on for the second suspect, identified as Dzhokhar Tsarnaev, 19 years old. Both brothers were believed to be involved in the fatal shooting of a Massachusetts Institute of Technology campus police officer during Thursday night's chaotic series of events.
