The mother of Boston Marathon bomber Tamerlan Tsarnaev knew as early as 2011 that her son had been radicalized and sent text messages to family in Russia suggesting he was willing to die for Islam, the FBI told lawmakers this week according to two officials with knowledge of the Capitol Hill briefing.
Tsarnaev, who was killed days after the April 15 bombing in a shootout with police, is said to have embraced radical Islam in recent years and recruited his younger brother, Dzhokhar Tsarnaev, to carry out the attack that killed three and wounded more than 180 near the finish line of the world’s most prestigious road race.
Dzhokhar Tsarnaev was caught alive but wounded on Friday and charged with use of a weapon of mass destruction, for which he could get the death penalty.
The FBI filed a federal criminal complaint against the 19-year-old on Sunday, and federal District Court Judge Marianne Bowler arrived at the hospital where he is being treated to preside over his initial hearing Monday, when she read him his Miranda rights.
