Brian Truchon, a 27-year FBI veteran and former deputy assistant director of the agency’s information technology services division, has been promoted to assistant director of the division.

Truchon joined the FBI in 1987 as a special agent to investigate white-collar crime and drug violations for the Salt Lake City division and transferred four years later to Los Angeles to help fight gang activity, the bureau said Thursday.

He led the Los Angeles Riots Civil Unrest and Grape Streets Crips gang investigations as a member of L.A.’s Joint Terrorism Task Force, served as supervisory special agent in the criminal investigative division’s safe streets and gang unit at FBI headquarters and started the Transnational Anti-Gang Initiative for the MS-13 National Gang Task Force.

Truchon also handled violent crime, public corruption, criminal enterprises and criminal undercover operations, training and support.

The psychology graduate from Arizona State University was an infantry officer in the U.S. Army before he joined the FBI.
