Sources: Tamerlan Tsarnaev Wanted to Die for Islam

FBI apparently said so at Congressional committee hearing

Boston Marathon bomber Tamerlan Tsarnaev sent text messages to his mother as early as 2011 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.
