BIDDEFORD, MAINE — California Rep. Robert Garcia and Connecticut Sen. Richard Blumenthal sent a letter to Department of Homeland Security officials on July 30, 2026, demanding details and records about the training and vetting of an ICE officer. The lawmakers sought information following the fatal shooting of Johan Sebastián Durán Guerrero, a 25-year-old Colombian immigrant, by an ICE officer in Biddeford, Maine, on July 13, 2026.

Garcia serves as the ranking member of the House Oversight Committee, while Blumenthal is the ranking member of the Senate Homeland Security Committee's Permanent Subcommittee on Investigations. The letter was addressed to Benjamine Huffman, director of the Federal Law Enforcement Training Centers, and Thomas Huse, chief counsel of the Federal Law Enforcement Training Centers.

The Associated Press identified the ICE officer who shot Durán Guerrero as David Brouillette. The Department of Homeland Security has not formally disclosed the name of the officer who killed Durán Guerrero.

Garcia and Blumenthal demanded records related to Brouillette's training, tests, and the investigation into the July 13 shooting. They asked if Brouillette underwent a condensed training process established by the Trump administration. The lawmakers also asked if Brouillette took a four-week online course to onboard as an ICE officer.

Garcia and Blumenthal asked whether a background check was conducted on Brouillette before he entered or graduated from training. David Brouillette told relatives he was hired by ICE in 2025. Relatives that David Brouillette struggled with mental health challenges and had a history of abusive and violent behavior.

The lawmakers requested information about ICE training procedures, citing testimony from a former ICE instructor who described the procedures as "deficient, defective, and broken." "The dangers inherent in the deployment of untrained and unqualified officers and agents to the streets demand oversight, accountability, and reform," Garcia and Blumenthal wrote.

ICE announced in June 2026 that it would scrap its shortened curriculum and mandate additional training for participants. The Department of Homeland Security stated that Durán Guerrero's vehicle attempted to flee the scene and an officer discharged his weapon fearing for public safety.

The Department of Homeland Security stated that the ICE Office of Professional Responsibility applies personnel vetting regulations and evaluates all available information for every applicant. The agency stated that it responds to official correspondence through official channels.

The Department of Homeland Security condemned the publicizing of ICE officers' identities, stating it puts their lives and families at risk. On June 3, 2024, the President signed a Proclamation under sections 212(f) and 215(a) of the Immigration and Nationality Act suspending and limiting the entry of certain noncitizens into the United States during emergency border circumstances.

The demand for records shows ongoing scrutiny of federal law enforcement training standards and personnel vetting processes. The events described span two years, from 2024 to 2026, connecting recent policy changes to current operational outcomes.

The shooting occurred shortly after ICE announced changes to its training curriculum in June 2026. The lawmakers' inquiry seeks to determine if the officer involved was subject to the shortened curriculum or other expedited onboarding methods. The response from the Department of Homeland Security emphasizes existing vetting protocols while raising concerns about the safety implications of disclosing officer identities.

Why It Matters

This inquiry determines whether expedited onboarding methods and condensed training curricula contributed to the deployment of an officer with reported mental health challenges. The outcome could validate concerns about deficient vetting procedures or confirm existing personnel regulations applied correctly. Results from this oversight effort may influence future standards for federal law enforcement recruitment and accountability.
