Boston Marathon Bombing

CIA Added Dead Bomber's Name to Terror List Months Before Bombing

That's going to lead to some awkward questions

The CIA added the name of the dead Boston Marathon bombing suspect to a U.S. government terrorist database 18 months before the deadly explosions, U.S. officials told The Associated Press on Wednesday.

The CIA's request came about six months after the FBI investigated Tamerlan Tsarnaev, also at the Russian government's request, but the FBI found no ties to terrorism, officials said.

The new disclosure was significant because officials have said the U.S. intelligence community had no information leading up to the April 15 bombings that killed three people and injured more than 260 others. That one of the bomber's name was in a terrorism database for 18 months before the attack was expected to drive congressional inquiries about whether the U.S. government adequately investigated tips from Russia that Tsarnaev posed a security threat.
