Paul posted a blow-by-blow on last night's manhunt (and I covered the related MIT officer shooting before that) for the suspects of the Boston Marathon bombings. More good summaries are at Slate and AMERICABlog.

In short: One of the suspects has reportedly been shot and killed by police. He is 26-year-old Tamerlan Tsarnaev, who was identified yesterday as suspect 1. The other suspect is his brother, 19-year old Dzhokhar Tsarnaev named by the FBI as suspect 2, who is still on the loose.

Police are blanketing Watertown. This seems to be the best summary of the situation right now:

Boston and its surburbs, universities and transit system were on total lockdown Friday as police hunted for marathon bombing suspect Dzhokhar Tsarnaev — on the loose after his accomplice brother was killed in a stunning chain of events that left one cop dead and another injured, officials said.

Authorities were confronting a double-edged nightmare: a ruthless killer at large in a densely populated area and a four-mile stretch of road possibly littered with explosive devices tossed from the suspects' getaway vehicle during a wild chase and firefights.

Two unidentified people were taken into custody at the Cambridge, Mass., home where Dzhokhar Tsarnaev and his older brother Tamerlan grew up, but they were not being described as additional suspects. Three dozen FBI agents were ringing the house.

Twitter is stuffed with misinformation, but it also has the best, up-to-the-minute accurate information. Sift through it all here at the hashtag #Watertown.

UPDATE 7:19 AM: Al Jazeera is reporting, "Police have detained two other people being described as accomplices and not suspects" and that all of Boston remains on lockdown, while police have sealed a 12-block district. Meanwhile, lots of people are tweeting photos like this one of officers surrounding a home:

UPDATE 7:50 AM: The New Republic has an interesting read on Chechnya:

The U.S. hasn’t paid much attention to Chechnya since the early 2000s, when the Bush Administration largely declined to intervene as rebels fought a bloody war against Russia. But with the news that the suspected Boston bombers were ethnic Chechens who moved to the United States from Dagestan in 2002, it’s time to get caught up on the separatist, predominantly Muslim Caucasian province. We’ll have more soon, but here’s what to read now:

The Council on Foreign Relations’ backgrounder on Chechen terrorism, which describes the attacks Chechen nationals have launched in public places, against Russian-backed government buildings, on apartment buildings and trains. Chechnya has also been an Al Qaeda recruiting ground.

Read the whole thing.

UPDATE 10:00 AM: Here's a link to the Boston police scanner, where there's some interesting acitvity. The standard warning applies: Not every comment on the scanner is necessarily the gospel truth and some of it's rumor, etc. and so forth.
