FBI: we didn't track elder bombing suspect

Responding to claims from the mother of the two Boston bombing suspects, the FBI said today it had not been tracking her oldest son, nor had the bureau spoken with him last week after the deadly marathon bombing. The only communication the FBI claims to have ever had with Tamerlan Tsarnaev "was an interview agents conducted with him in 2011 at the urging of a foreign government, since identified as Russia."
