One of two suspects in the deadly Boston Marathon bombing is dead and a massive manhunt is underway for another, authorities said early on Friday.

“We believe these are the same individuals that are responsible for the bombings on Monday at the Boston Marathon,” said a police spokesman just after dawn. “This is a very serious situation that we are dealing with.”

The Middlesex district attorney said the two men are suspected of killing a Massachusetts Institute of Technology police officer on campus late Thursday, then stealing a car at gunpoint and later releasing its driver unharmed. Hours earlier, police had released photos of the marathon bombing suspects and asked for the public’s help finding them. A new photo of the suspect on the loose was released later showing him in a grey-hooded sweatshirt. It was taken at a 7-Eleven store in Cambridge, just across the river from Boston. (FBI)

The FBI asked that anyone with information on the two men to call 1-800-CALL-FBI or visit a special FBI website at bostonmarathontips.fbi.gov

Who Is Dzhokhar Tsarnaev, the Man at the Center of the Boston Manhunt? – The Atlantic Wire

This morning, after a chaotic evening saw his partner in crime (and apparently his older brother) killed and as a city locked down to find him, Dzhokhar A. Tsarnaev emerged as the name of the man in the ongoing manhunt in Boston Friday. According to information culled from multiple unconfirmed reports, Tsarnaev is a 19-year-old reportedly from Kyrgyzstan who has been living, for the past year, in Cambridge, Massachusetts. Here’s everything else we think we know about “Suspect No. 2” — a.k.a. the one in the white hat, the one authorities apparently saw drop a bomb-laden backpack in security footages — based on the flood of incoming reports: His name is Dzhokhar A. Tsarnaev […]

His Uncle Called Him a Loser

He May Have Run Over His Own Brother

NBC’s Williams says that Dzhokhar ran over his brother to get away from the firefight with police last night.

“I Don’t Have a Single American Friend.”

A photo essay of Dzhokhar’s brother Tamerlan is being passed around the Internet today. We’ve contacted photojournalist Johannes Hirn, to verify Tamerlan’s identity. What matches up is Tamerlan’s place of birth (Chechnya), his age, and his name. In the essay, “Will Box for Passport”, Tamerlan Tsarnaev said: “I don’t have a single American friend, I don’t understand them.”
