WASHINGTON – A foreign government told the FBI in early 2011 about information that Tamerlan Tsarnaev, one of the brothers suspected in the Boston Marathon bombings, was a follower of radical Islam.
Tamerlan Tsarnaev died in a shootout, and his wounded younger brother was captured alive. They were identified by authorities and relatives as ethnic Chechens from southern Russia who had been in the U.S. for about a decade.
According to the FBI, the foreign government said that based on its information, Tamerlan Tsarnaev was a strong believer and that he had changed drastically since 2010 as he prepared to leave the U.S. for travel to a region in the country to join unspecified underground groups.
The FBI says it interviewed Tsarnaev and relatives, and did not find any domestic or foreign terrorism activity.
