The bombing suspects have been identified as Tamerlan Tsanaev, 26, and Dzhokar Tsarnaev, 19, Russian immigrants. At least one brother was born in Kyrgyzstan. After a wild night including holding up a Cambridge 7-Eleven, killing one M.I.T. police officer and critically wounding another, hijacking an SUV and throwing explosive devices in their path, Tamerlan is dead and Dzokhar is on the loose. The entire city has been ordered to shelter in place.

"We believe this is a terrorist, we believe he came here to kill people." police said in an early-morning press conference:

A violent crime spree across Greater Boston that took the lives of a campus police officer and one of the suspects in the Marathon bombings morphed into a desperate door-to-door search for a man believed to be the second bomber in Monday’s dual blasts.

After a string of explosions and volleys of gunfire that seriously injured a transit officer, police cordoned off much of Watertown, Mass. Residents were ordered to “shelter in place” and not trust anyone they might see other than uniformed officers.

A Massachusetts State Police public information officer told HuffPost reporter Michael McLaughlin, "We believe this to be a terrorist, we believe he came here to kill people."

The City of Cambridge awarded "Dzhokhar Tsarnaev" a $2,500 scholarship in 2011,according to Boston.com report. "The city is awarding the $2,500 scholarships to 45 students using contributions from citizens and businesses. About 35 to 45 scholarships are awarded each year, according to the city," reported Boston.com's Brock Parker.

Tsarnaev was a senior at the Cambridge Rindge and Latin School then. This time frame would make sense if the AP is reporting that Tsarnaev was in the U.S. for at least a year.
