Retired agent Bob Clifford served with the FBI for 24 years. In this episode of FBI Retired Case File Review, he reviews the organization and operation of the transnational gang MS-13, Mara Salvatrucha, the most dangerous gang in America. In November 2004, Bob Clifford was asked by then FBI Director Robert Mueller to accept a special assignment to FBIHQ to establish the FBI’s MS-13 National Gang Task Force, and served as its first Director. For the next 18 months, Bob led multi-agency and multi-national efforts to combat the infamous MS-13 and other violent transnational street gangs, to include several deployments throughout Central America to successfully garner international cooperation and intelligence-sharing. In addition to coordinating multiple law enforcement field operations, Bob was required to appear before White House, Congressional, and Cabinet-level officials on a regular basis. The task force is now known as the Transnational Anti-Gang (TAG) Task Force initiative. Bob Clifford was previously interviewed on Episodes 96 and 97 of FBI Retired Case File Review about his investigation and capture of the only surviving hijacker responsible for the hijacking of Egypt Air Flight 648.

Jerri, you did an amazing job in this interview. I truly enjoyed learning about this problem.
I became one of your avid listeners after I heard this Podcast. Looking forward to reading your books! Thanks!!!

Wow, you’re right about that picture. It’s shocking.

I’m told the guards don’t go inside. After living like caged animals, once they’ve served their time those prisoners will be released back into society.

You must be proud to know all its major agents, you really lucky.

Yes, I am very fortunate to be a member of the FBI family. I’m thrilled to have the honor of presenting these case reviews to you.
