Police sealed off densely populated portions of the Boston metro area early Friday
after a violent night of chasing the Boston Marathon terror suspects left one of the men and a police officer dead.
The manhunt effectively shut down a large portion of the nation's fifth-largest metro area.
Developments moved quickly:
-- Police swarmed over a Watertown, Massachusetts, neighborhood looking for the surviving suspect
, identified by Boston police as Dzhokhar Tsarnaev, age 19.
-- The slain suspect
was wearing explosives and a triggering device when he died, a source briefed on the investigation told CNN's Deborah Feyerick. Several sources identified him as Tamerlan Tsarnaev, 26. He was the fugitive suspect's older brother.
-- A Maryland man who said he was the suspects
' uncle told CNN affiliate WBZ that Tamerlan Tsarnaev "got what he deserved." "What can I say for people who have been murdered? Sympathy," Ruslan Tsarni, referring to those who died in the bombings at the Boston Marathon.
Despite the lack of information about how the suspects are implicated in the Marathon Day bombings, the police is keeping all residents of the area in a lock-down and a state of shock, while they patrol the streets fully armed and using the "bombing suspect" excuse to abuse anyone who they deem "suspect". Boston today is officially a Police Sate.
