[Bolduan:] Breaking news out of California. Investigators have found an ISIS connection.
[Berman:] I want to bring back our CNN chief national security correspondent, Jim Sciutto, who broke the story; our CNN terrorism analyst, Paul Cruickshank. Jim, gives us the details.
[Jim Sciutto, Cnn Chief National Security Correspondent:] John, here's what we know. Multiple officials telling CNN that as this attack was under way, the wife of the shooter, Tashfeen Malik, she posted to a Facebook account, a pledge of allegiance to ISIS leader, Abu Bakr al Baghdadi. They believe it was an account linked to her under a different name. To be clear, investigators looking at this as an ISIS-inspired attack. They have not established this was directed by an ISIS leader. In other words, that ISIS reached out and said, attack this target on this date. It looks more like something in terms pursuing their radicalization. In addition to that, they are still looking to see whether the workplace a dispute at the workplace, particularly over religion, may have played an additional role. But this firming up the idea that this was an act of terrorism with a direct link to ISIS. I should say this, posting a pledge of allegiance has precedence. You may remember the Garland, Texas, shooters. They as the same time or just prior to the attack posted allegiance, pledge of allegiance to the ISIS leader as well John and Kate?
[Bolduan:] And, Paul, the fact the fee maim attacker posted this. Also this on top of we even heard from a coworker of Farook's, he raised possibility to CBS News that he thought it was the wife who helped radicalize Farook. What do you make of that?
[Paul Cruickshank, Cnn Terrorism Analyst:] Well, again, there's been some precedent for that. We all remember in January those that carried out their attack on the kosher market, some allegations she helped in some degree, radicalized him. There have been other cases of husbandwife teams carrying out Islam terror attacks. We saw a case of a Belgian couple in Iraq carrying out suicide bombings on the same day. In Holland, around that time, a husband and wife went to assassinate a Dutch politician that the Dutch actually thwarted that attack. Not unheard of, but not where you would there have been some where the female has been more radicalized, playing the Lady Macbeth role. I've seen that in cases I've studied over the years. I've interviewed some of these women over the years who have been encouraging their husbands to beunquote, "men" when it comes to jihad.
[Bolduan:] Scary regardless. Paul, thanks so much. Jim, that's a huge line of questioning. I'm sure investigators are looking into the all digital, electronic evidence they're trying to gather and work though at this point. Jim, we'll look for you on more on that. Thanks, guys. Thanks so much. Coming up next for us, "unspeakable carnage," that's how one of the officers first to the scene describes what he saw. In his own words, ahead.
