Jamie A. Flowers Jr.

Chief, Criminal Division


Jamie A. Flowers Jr. was appointed as Chief of the Criminal Division in January 2022. As Criminal Chief, Mr. Flowers supervises all investigations and prosecutions by the U.S. Attorney’s Office (“USAO”) across a wide range of practice areas, which include fraud and financial crimes, cybercrime, public corruption, child exploitation, and narcotics and firearms offenses. Prior to his appointment as Chief, Mr. Flowers served as Deputy Chief for two years.

Chief Flowers began his tenure as an Assistant United States Attorney (“AUSA”) in the Middle District of Louisiana in 2014. During his time as an AUSA he managed a diverse and challenging caseload including drug trafficking, human trafficking, child exploitation, and affirmative civil enforcement. As an AUSA, he led multiple OCDETF investigations resulting in the disruption and dismantlement of some of the most dangerous violent-crime organizations in and around Baton Rouge. Chief Flowers also served as the District’s Human Trafficking Task Force Coordinator where he worked to create a broad, community-based effort to combat human trafficking. In this role, he received a commendation from former FBI Director Jim Comey for his efforts in coordinating the investigation and prosecution of one of the largest FBI-led commercial sex trafficking investigations in Louisiana. Additionally, Chief Flowers serves as the District’s Re-entry and Prevention Coordinator. In this role he led the office’s efforts in partnering with the U.S. District Court for the Middle District of Louisiana to establish the District’s first re-entry program, Rehabilitating Individuals through Strategic Encounters (“RISE”) Court, which has been up and running since 2016 under the leadership of Chief Judge Shelly Dick and Magistrate Judge Erin Wilder-Doomes.

Prior to working in his role as a federal prosecutor, Chief Flowers worked as a trial attorney with the U.S. Department of Homeland Security representing FEMA in legal actions related to Hurricane Katrina Public Assistance disaster relief funding. Before joining FEMA, he served in the United States Army as officer in the Judge Advocate General’s (“JAG”) Corps, where he achieved the rank of Captain.

Chief Flowers attended Hampton University on a four-year AROTC scholarship and graduated, cum laude, with a Bachelor of Arts in History. Upon completion of his undergraduate studies, he attended Mercer University School of Law and was admitted to the practice of law in 2009.

Some of Chief Flowers’s community involvement includes serving as an Executive Board member of the Baton Rouge Chapter of the Federal Bar Association, chair of several committees of the Baton Rouge Bar Association, Louisiana State Bar Association Region III Mock Trial Coordinator, and member of the Wex Malone American Inns of Court.

For his years of federal service, his high standards of professional achievement, his outstanding legal ability, and his significant contributions to the legal community and the Baton Rouge community as a whole, Chief Flowers received the Federal Bar Association’s 2021 Younger Federal Lawyer Award.
