Tamerlan Tsarnaev's phone number was traced to numbers that came up in two other investigations into terror suspects, according to a senator who attended classified briefings about the Boston attack investigation. The connection between Tamerlan Tsarnaev and the two other suspects was "twice removed," meaning he was in contact with people who had been in contact with the suspect, a U.S. government official said.Likewise, the Boston Globe reported:
Investigators also linked Tamerlan Tsarnaev’s phone records to two other phone numbers for people who had been investigated for terror, the official said. But the two other terror cases were closed. It’s not clear when the FBI discovered those phone links or when those cases were closed.Well, the FBI should start thinking about reopening those cases.
The Tsarnaev brothers may not be the lone wolves they've been portrayed to be, but rather two wolves who are part of a broad pack of wolves.
