BOSTON, Mass. (CNN) –Three friends of Boston Marathon bomb suspect Dzhokhar Tsarnaev have been jailed on charges they tried to throw investigators off Tsarnaev’s trail, federal prosecutors announced Wednesday.
Two of them, Azamat Tazhayakov and Dias Kadyrbayev, were already in federal custody on immigration charges, their lawyers told CNN.
Both are from Kazakhstan and had student visas.
The third, Robel Phillipos, is a U.S. citizen.
