Media Sifting Through Boston Bombing Suspects' Social Media
Brothers from Chechnya
The suspects involved in the Boston Marathon bombings were brothers from the Russian Caucasus who'd lived in the United States for several years, though one noted on a social media website that he didn't "have a single American friend."
The elder brother, identified by several sources as Tamerlan Tsarnaev, 26, studied engineering at Bunker Hill Community College but had taken off a year to train as a boxer.
