He's The Reason Boston's Shut Down Today

There were some big developments in the Boston bombing case yesterday afternoon and last night. After releasing an image of two suspects yesterday afternoon and identifying them as Chechen brothers Tamerlan and Dzhokhar Tsarnaev, 26 and 19, authorities received word at around 10:30 eastern time that the men had robbed a 7-Eleven in Cambridge.

The Tsarnaev brothers escaped, though, and then reportedly headed to MIT, where they fatally shot a security guard, carjacked a Mercedes SUV, including the driver, whom they released about a half-hour later, and then, in an even more violent scene and with the police on their tail, the men opened fire and lobbed an explosive device toward police. It was messy, smoky scene but no one was hurt, thankfully.

Authorities opened fire and struck one of the suspects, the elder Tamerlan Tsarnaev, and took him into custody and to a local hospital, where doctors discovered what appeared to be an explosive device strapped to his chest. He died from multiple gunshot wounds, leaving his brother at large.

There are some conflicting reports on the men's origins and time in the United States, but from what we know Tamerlan Tsarnaev, the older, deceased brother, was born in Russia and his younger brother was born somewhere in

Kyrgyzstan. According to some reports, the men came over to the United States about a decade ago, when their family sought political asylum. The boys would have been about 16 and 9 at that time. At least one of them, Tamerlan, had permanent legal status here, according to NBC News. Another report claims Dzhokhar Tsarnaev, the suspect at large, spent some time in Turkey before coming here, or returning here, two years ago, in 2011, the year he received a $2,500 scholarship from the city of Cambridge. He also has a Massachusetts driver's license. Both men are assumed to have military experience and to have had one thing on their mind the past few days: terror.

"We believe this to be a terrorist," said Boston Police Chief Ed Davis. "We believe this to be a man who's come here to kill people. We need to get him in custody." Massachusetts Gov. Deval Patrick is ordering Bostonians to stay indoors today as authorities comb the area for Dzhokhar Tsarnaev, a man they consider armed and dangerous. Subways and buses in the city are closed, and people out and about are told not to congregate in public spaces, lest they become a target for the lone brother.
