US intelligence agencies added the mother of the Boston bombing suspects to a government terrorism database 18 months before the bombings, two officials said.from ... Zubeidat Tsarnaeva was added to terror database ...
The CIA asked for the older suspect, now dead, and his mother to be added to a terrorist database in the autumn of 2011, after the Russian government contacted the agency with concerns that both had become religious militants, according to officials briefed on the investigation.
