Boston Marathon Bombing Suspects Are Russian

From Philly.com: One of two suspects in the Boston Marathon bombing is dead after the killing of a university officer and a shootout with police, and a massive search is underway for the other, authorities said early Friday.
Police are locking down some neighborhoods in Boston and its western suburbs as they search for the remaining suspect: known as the man in the white hat from marathon surveillance footage.
That man dropped the bombs at the race finish lane, Boston Police Commissioner Edward Davis said, according to the Boston Globe.
Authorities have not named the suspect, though the Associated Press identified the surviving suspect as 19-year-old Dzhokhar A. Tsarnaev, of Cambridge, Mass.
The suspects are from a region of Russia near Chechnya and had lived in the United States for at least one year, the AP reported. The two are brothers, according to NBC News.
Officials urged residents in Watertown, Newton, Waltham, Belmont, Cambridge and the Allston-Brighton neighborhoods of Boston to stay indoors. All mass transit was shut down and businesses were asked not to open Friday. People waiting at bus and subway stops were told to go home. 
"We believe this to be a terrorist," Davis said of the suspect on the loose. "We believe this to be a man who's come here to kill people. We need to get him in custody."
Television news footage showed police going door to door in the neighborhoods.
The Middlesex district attorney said the two men are suspected of killing a Massachusetts Institute of Technology police officer on campus in Cambridge late Thursday, then stealing a car at gunpoint and later releasing its driver unharmed. http://www.philly.com/philly/news/1_Boston_Marathon_bombing_suspect_dead_2nd_at_large.html
If they are from Chechnya, they are probably some bad ass dudes as the Chechen people have taken on Russia and at times, kicked their butt.
