One Bombing Suspect Dead; Manhunt Underway for Second; Boston-Area in Lockdown

Boston and several suburbs, including Cambridge and Watertown, were under a massive lockdown Friday morning, as police conduct a house-to-house search for at-large Marathon-bombing suspect 19-year old Dzhokhar Tsarnaev.

The suspect’s older brother, Tamerlan Tsarnaev, 26, was killed last night after a shootout with police in Watertown.

Yesterday, the FBI named the two brothers as suspects in the Boston Marathon bombings that killed 3 and injured over 170. Video taken at the Marathon, showing Dzhokar in a white backward baseball cap, and Tamerlan in black baseball cap and sunglasses, and each of them carrying a backpack, was released to the public, along with the warning that the boys were armed and dangerous.

News sources are still trying to cull biographical information about the suspects, from relatives, friends, and social media pages. The brothers are Chechen Muslims who immigrated to the U.S. about a decade ago. They attended schools in the Boston area; Tamerlan was an aspiring boxer, who professed an interest in boxing for Team USA in the Olympics – if Chechnya has not yet achieved its independence from Russia – despite having reportedly said, “I don’t have a single American friend, I don’t understand them.”

The brothers – perhaps feeling the pressure – went on a deadly crime spree last night, robbing a convenience store, carjacking a Mercedes, killing an MIT security guard Sean Collier,  and critically wounding  transit officer Richard Donahue.

The suspects fled, and engaged in a shootout with police; reportedly, the suspects were armed with military-grade explosives. Tamerlan was killed in the shootout; the attending physician reported that he had sustained wounds from an explosive, with some news reports stating he had an IED.

The younger brother managed to escape, and sent Boston and the surrounding areas into total lockdown Friday morning, as law-enforcement officials undertook a massive manhunt. All public schools, colleges, and public transportation in the area were closed; residents were urged to stay indoors and open their doors for no one except law enforcement, who were conducting a house-to-house search. Business owners were urged not to open their businesses.

A no-fly zone has been enacted over the area, as one of the most intense manhunts in memory is undertaken for the 19-year old suspect.
