Despite all the reports from classmates and friends that Dzhokhar Tsarnaev, the second suspect in the Boston Marathon bombings, was unlikely to be involved in any sort of extremist activity, new information about the 19-year-old seems to indicate that he and his brother, the now deceased Tamerlan, lived a shocking double life.
According to reports, the elder Tsarnaev's behavior changed drastically in the last three or four years, and upon returning from an extended trip to Russia in August of 2012, posted multiple videos to his private YouTube page featuring a militant Islamic group in his native Chechnya area, known as Imarat Kavkaz.
However, according to Watertown Police Chief Edward Deveau:
"From what I know right now, these two acted together and alone. I think we have to be ever vigilant, and we're learning as we go along, but as far as this little cell — this little group — I think we got our guys."
