According to a source briefed on the investigation, the suspects involved in the Boston bombing are originally from the Russian Caucasus and had moved to Kazakhstan at a young age before coming to the United States several years ago.
Another source, from federal law enforcement, also told CNN that the man being sought has been in the United States for at least a couple of years.
The man identified as Tamerlan Tsarnaev, the older brother, had studied at Bunker Hill Community College and wanted to become a engineer, the source said. He then took a year off to train as a boxer.
The source told CNN’s Deborah Feyerick that a posting on a social media site in his name included the comments: “I don’t have a single American friend. I don’t understand them.”
The source added that it should not be assumed that either brother was radicalized because of their Chechen origins.
