Boston Police Commissioner, ca. 4am:

One suspect dead. One at large. Armed and dangerous. White hat suspect at large.
I’ve been listening to Channel 7/WHDH’s live feed since 11:30pm last night.
Here’s the Boston Globe:
WATERTOWN — One suspect in Monday’s Boston Marathon bombings has been apprehended, according to an official with knowledge of the investigation. Another appears to remain on the loose in Watertown after a firefight with police. A 20-block perimeter was established as authorities searched for him.
A scene of chaos descended on Cambridge and Watertown late Thursday night and early Friday morning, as police confirmed an MIT police officer was shot and killed, and an apparent carjacking led police on a frenetic chase into Watertown. Hundreds of police officers flooded Cambridge and Watertown.
A spokesman for the MBTA said that a transit officer had been shot and was in serious condition.
Witnesses in Watertown said they heard explosions. Police officers were screaming about improvised explosive devices…
The bedlam in Watertown was preceded by a spasm of violence in Kendall Sqaure, in Cambridge.
An MIT officer, who has not been identified, was shot multiple times at 10:48 p.m. Main and Vassar streets, near Building 32, better known as the renowned the Stata Center. No one else was hurt, and no arrests had been made by early Friday.
That shooting sparked a massive manhunt, which fanned out from Kendall Square over an area that had endured a tragic and tumultuous week, in the aftermath of the fatal explosions at the marathon.
Police officers and canine units swept the campus, and a big swath of Vassar Street was blocked.
The university issued an alert to students and faculty to remain inside, which was later lifted….
Things are definitely in the Fog-of-War state right now. Local tv news got a headstart on this situation, because all stations were doing “President Obama came to Mass General Hospital today to meet Marathon victims and first responders” live feeds for the 11pm broadcasts when the first police cruisers barrelled up to the emergency entrance with the dying MIT officer. Everyone’s been up all night, racing from point to point, listening to sirens and gunshots and multiple explosions — none of them normal occurances in this area of Cambridge/Watertown/Boston.
I’ll put up another thread if there are Big Developments in the next couple hours, but for the record, we live a dozen or so miles from the scene so all I know is what I hear in the media.
ETA: Classes at MIT and Harvard and Emerson have been cancelled for the day.
ETAA: Wow. All MBTA bus & subway service has been ‘suspended’. People in Watertown and the abutting communities — Newton, Waltham, Belmont, Allston/Brighton, Cambridge — are being told to ‘shelter in place’ and stay home. (It’s school vacation week, for public schools.) ‘No vehicle traffic will be permitted’ in or out of Watertown; businesses will not be permitted to open.
UPDATE, 6:50am: Channel 7 says the suspects have been identified as brothers from Chechnya, with ‘Turkish military training’, permanent residents living in Cambridge for most of the last year. The survivor (“White Hat”) is said to be 19-year-old Dzhoxhar Tsarnaev (no guarantee on the spelling, it’s past my bedtime).
ThinkProgress has a summary that matches what I’ve been hearing overnight:
The two robbed a 7/11, killed a Massachusetts Institute of Technology (MIT) campus police officer in his car after 10 PM on Thursday night and later carjacked a Mercedes SUV. The owner of the car was held at gunpoint for 30 minutes and later released near a gas station in Cambridge. The men then led police on a chase to Watertown, where they exchanged gunfire and threw bombs out of the vehicle window at law enforcement, including one made from a pressure cooker. They stop the car in Watertown, where the first suspect got out, was shot and likely detonated an improvised explosive device (IED) strapped to his chest. The second suspect drives on and later abandons the car.
SWAT teams are going door to door in Watertown, sending residents out of their homes and searching every inch of every property.
