Law enforcement officials in San Bernardino and Los Angeles may have investigated Syed Farook one week before the shooting on the community development center on December 2, 2015, that left 14 dead and 17 injured, according to a review of police communications immediately following the attacks.

Federal and local authorities have insisted that neither of the attackers had aroused suspicion before the assault earlier this month and that both Syed Farook and his wife, Tashfeen Malik, were unknown to law enforcement and US intelligence. But conversations between law enforcement officials in the hours after the shootings leave a different impression.

Farook is first identified by name at approximately 11:40am local time, just a half hour after the shooting began. The information came from a county worker, who noted that Farook had been acting nervous and left the holiday party twenty minutes before the shooting began.

In a subsequent exchange at approximately 12:08pm the dispatcher addresses an officer nicknamed "Trav" upon hearing "Syed Farook." She says: "Reference that name, I believe one of the [garbled] was working that name up for something last week. I'll have to check."

In a second exchange shortly after 12:20, another officer says of Farook: "I just got some info from that LAPD that they have information on one of your suspects. I heard that somebody was trying to INV that guy. Can you find out who I can give this information to?"

A third exchange, two minutes later, follows:

Officer 2: [garbled] I had received a call [garbled] that had some information that they had ran the guy or something last week and I was going to give it to your intel guys.

Officer 1: Okay, that's what I was trying to get you to. If you're at the mobile command – uh, what's your 20?

The San Bernardino Police Department did not respond to inquiries by press time. Officer Rosario Herrera, a spokeswoman for the Los Angeles Police Department, told TWS that she wouldn't be at liberty to discuss any prior investigation. "As I'm aware, we don't have any information." (Audio of the scanner traffic was provided via Broadcastify by "Jason Beale," a pseudonym for a former senior US intelligence official.

Scanner traffic is often unreliable, particularly in the immediate aftermath of an active shooter incident. It's possible that the officers who discussed the prior investigation were mistaken. But it's at least clear that several officers believed that Farook had been the subject of an earlier investigation.

A transcript of five calls concerning Farook and a potential previous investigation follows. The calls took place between approximately 11:40am and 12:40pm pacific time.

1) The first exchange, between an unidentified San Bernardino police officer and the dispatcher, comes at 11:40am, approximately 30 minutes after the shooting began. The call follows a police interview with a witness to the shooting and includes the first mention of Farook's name.
