These are the same people who shot MIT guard this evening, hijacked a car.

One suspect now on foot.

Spruce & Lincoln streets. Plain clothes officers being asked to maintain perimeter.

Wider perimeter being set up - out to Mt. Auburn Street.



Expanding perimeter to 3 blocks from 98 Spruce.

Bomb squad on the way.

Officers asked to turn off all cell phones.

Bomb squad asking which of multiple locations they need to deploy.

Package on the ground on Mt. Auburn street.

Another location already has a robot being sent in.

Request for description of the person at large.

One suspect being taken to hospital.

Watertown officer down.

2 suspects, 1 in custody, 1 possibly on the ground and being held until arrest(?) (One officer has requested clarification)

All officers asked to switch channel.

Watertown asking for assistance at 11 Appleton Street - may or may not be related.

The officer down in Watertown is being brought to hospital now.

Trying to get confirmation that 2nd suspect is the right suspect.

Just warned to watch for booby traps as officers head into the area to check yards.

Reporting now that they may not have caught the 2nd suspect.

Call for investigators at Mt. Auburn and Dexter to yellow-tape a 2 block area.

All unnecessary cruisers being moved down the street to open up the road to make room for movement. Too many cars are now blocking the street.

Media is now getting in the way, asked to get off the street, move to perimeter.

20 more officers have arrived.

Asking for description of escaped suspect...

Dividing into quadrants to search.

Code black called at Mt. Auburn hospital in Watertown. I looked it up - at Mt. Auburn, that means bomb scare.

Sweep is continuing. It's slow and methodical, so don't expect much in the way of rapid updates.

Suspects used "long guns" not handguns.

Sweep still going....

I must say, the calm, professional, methodical way this is being handled is very impressive.

Description just put out of a white male considered extremely armed and dangerous.

General notice just given to all officers to be looking for "extremely" armed and dangerous suspect with some clothing description.

Another live stream: http://www.necn.com/...

Police scanner feed has gone offline.

Foot pursuit in progress. Expanding perimeter

Sending SWAT to aid in pursuit

Trying to confirm the pursuit.

Now reporting no foot pursuit.

"Let's make sure we're not chasing ghosts, here." Admonition just came over the scanner.



K-9 unit is going to check a location with an open door

Asking for a school bus to evacuate some of the people from nearby homes due to "the devices"

Bus is more to keep people warm, while they're being kept out of their houses.

Suspect wearing charcoal gray hoodie, they didn't see his pants. Dark, fluffy curly hair.

Doubling up the posts at the perimeter

More sweep assignments being made.

Police expecting to gain advantage when daylight returns.

Going to try to move "devices" asking for bear(?) [hard to hear]

Apparently it's a bearcat armored vehicle. They want shelter for all the people in the area before they move the device.

Arsenal and Dexter streets.

Another location (100 Talcott) has motion sensors going off. A team is staging there.

Arsenal and Dexter is the "device" location. Bearcat is on the way. They were having trouble getting the original one there, due to clogged streets, but found another one with a better route.

Open door on another street (Adams), which is in the opposite direction from Talcott.

Trying to determine what weapons have been found so far. Sounds like only the explosives, which means the long guns are still missing.

Sending investigators to another address.

DoD k9 being requested

fire department ready to help out

DoD K9 could be EoD K9. Hard to hear.

Police going to a location, told to not use radios there.

Box with wires found.

Sounds like a vehicle that's en route is getting amusing directions from GPS. It's hard to tell exactly, due to the sound cutting out.

Asking sweep teams to call in locations as they complete them.

K9 en route to open door.

Bearcat still en route

Checking out a car near one of the buildings.

Person with backpack spotted in another location.

Now checking area with backpack wearer.

Barriers being brought in via DPW truck.

1st suspect had a bomb on his chest, which detonated after he was arrested (perhaps that was the code black at Mt. Auburn hospital?)

Second suspect may also have one.

Warning officers to be careful if they find the second suspect.

Tactical commanders at the staging area are being brought in for briefing.

Bus still hasn't arrived for residents.

Trying to get someone to close the bike paths that go through the neighborhood. Commuters have started heading to the city.

Officer approaching suspect: "Get down on your knees, sir."

Dispatch now asking for location of officer who said that.

Not a person of interest.

A suspicious package has been reported in the area of 500 Memorial Drive (near MIT). People asked to remain out of the area.

I don't know if it's related, but 3 officers are reported injured at the command post.

Bus is almost in place, then evacuation begins.

Hard to tell if Mem Drive alert was canceled, or if they're sending a bomb sniffing dog.

Mall has been opened for evacuees to use ... once they're evacuated.

MIT package not a problem.

Doing a roll call ...

Industrial Park at 480 Arsenal is inside the perimeter, so not allowed. If you know folks who work there (Verizon, etc., tell them to stay home).

Bus FINALLY arrived, people have boarded, being taken to another location. Another bus is available if needed later.

Sky is starting to lighten up, it'll be light out soon.

Determining whether residents can be allowed to go to work.

Report of male with heavy backpack on bike

Work ok for those on streets that have been cleared.

Personnel on fixed posts are to remain there until relieved, regardless of when shift would normally change.

Hospital press conference - does not say there was an explosive device on suspect who had been brought there. Suspect died of cardiac arrest. This was the suspect arrested 4-ish hours ago after the shootout/hand grenade event. (getting a great understanding of how news reports can be so jumbled and incorrect)

More sweeps in progress...

Calling for a negotiator...

School closings being announced in Boston.

MIT is closed today (not a surprise)

If you know people in Boston and vicinity, tell them to check for school closings here: http://boston.cbslocal.com/...

All MBTA (public transit - subway and bus) service closed.

Police asking if MBTA service is actually closed. Not confirmed.

Confirmation: All MBTA trains (subway and commuter rail) are suspended.

No word about buses.

With the sun coming up, things are ramping up

FBI "in the grid" and they're tightening up the perimeter.

Asking people in Watertown and 6 surrounding towns to STAY INDOORS. Do not answer door (except for police) and do not congregate outside.

Noises reported at a house.

Bringing additional arms to the officers staffing the perimeter.

Fog rolled in.

Report of someone trying to hitchhike.

It's been odd to hear how many homes have doors standing wide open - not really something you'd expect in the city, especially in early spring.

Sounds like prepping for a concerted effort....

A unit just reported a suspect in custody - the guy who was trying to flag down a cab - in a Boston cab. Requesting a bomb squad to check the car.

Note: above is not known to be a suspect, but one of the people called about by passers-by.

Lots of locations and lots of people being called in. Arrests and investigations into any of them do not mean they've found the second bomber.

A car has been stopped on Comm. Ave.

Well, it looks like no one's actually reading this, and there are other diaries covering the search, so I'm going to call it a night.
