(AP) - Police are locking down some neighborhoods in Boston and its western suburbs as they search for the remaining suspect in the marathon bombings.
Authorities urged residents in Watertown, Newton, Waltham, Belmont, Cambridge and the Allston-Brighton neighborhoods of Boston to stay indoors. All mass transit was shut down.
The announcement comes hours after the killing one suspect, known as the man in the black hat from marathon surveillance footage. The man in the white hat is on the loose and police are calling him a "terrorist" who came here "to kill."
