The FBI found nothing to link either
person to terrorism, and the FBI closed the investigations in June 2011. Then,
the Russians in the autumn sent the same warning to the CIA. The CIA asked the
US National Counterterrorism Centre to add the mother's and son's names to its
huge, classified database of people known to be terrorists and those who are
suspected of having terror ties, called the Terrorist Identities Datamart
Environment, or TIDE.
