The scourge of fentanyl addiction lit a fire under the Department of Homeland Security to launch multi-agency operations this year to stop the deadly synthetic opioid at the stages of its creation, importation, and distribution. Katrina W. Berger is the Executive Associate Director for Homeland Security Investigations (HSI), the principal investigative component of DHS, which has been a driving force every day in investigating, disrupting, and dismantling transnational criminal organizations – including through the agency’s ongoing Operation Hydra, which uses computer-based analytic tools to target TCO chemical supplies, Operation Pelican Bones, which includes a focus on financial tools used by criminal organizations, and Operation Chain Breaker, which targets equipment needed to manufacture pills. Berger oversees HSI’s workforce, which consists of over 10,000 employees including special agents, criminal analysts, and mission support personnel assigned to over 237 offices throughout the United States and across 56 countries. Prior to this assignment, Berger served as the Special Agent in Charge (SAC) for HSI Atlanta. Berger began her federal law enforcement career in 1998 as a special agent with the U.S. Customs Service in Tampa, Fla. She has held many key leadership positions within the agency: serving as the Assistant Director for the Mission Support Division in HSI Headquarters, Chief of Staff for the ICE Deputy Director, the Deputy Assistant Director of HSI’s Domestic Operations Division, and the Deputy Assistant Director for the Transnational Crime & Public Safety Division. She also served as the SAC in Dallas and Deputy Special Agent in Charge in New Orleans. Moreover, Berger was the first ICE Deputy Director of the Organized Crime Drug Enforcement Task Force Fusion Center. Prior to entering federal law enforcement, Berger served as an Assistant Public Defender in the Florida Keys and Tampa, Florida. She also served as an Assistant Attorney General with the State of Florida’s Office of the Attorney General in Tampa, Florida.
