ICE officer linked to Maine fatal shooting previously reported lingering cognitive issues from 2021 head injury
David Brouillette, an ICE officer present at a recent fatal shooting in Biddeford, Maine, had previously claimed lasting cognitive deficits from a 2021 workplace accident, raising questions about agency vetting and training practices.
An Immigration and Customs Enforcement (ICE) officer identified by two of his ex-wives as being present at a fatal shooting in Biddeford, Maine, previously told a court that a 2021 head injury left him with ongoing cognitive problems. The injury, which Brouillette said resulted from a steel I-beam falling on his head while unloading a trailer during firefighter training, caused a serious laceration, concussion, memory impairment, headaches, vertigo and light sensitivity, according to court filings.
Brouillette filed a lawsuit in late 2023 against the Maine Community College System, which ran the training program, alleging that the post-concussive symptoms significantly impaired his daily activities and prevented him from completing the certification. The case was later settled, a college spokesperson said.
In May, Brouillette, 37, was among the officers on the scene after 25-year-old Johan Sebastián Durán Guerrero was shot dead by ICE agents. Federal officials have not publicly identified the shooter, but the Department of Homeland Security said deadly force was used because the officer feared for public safety. Two of Brouillette’s ex-wives told CNN that he contacted them after the incident and said he had fired the shots, describing the action as justified.
Brouillette’s background includes service in the Maine National Guard and the U.S. Army from 2007 to 2015, deployment to Afghanistan, and stints as a state correctional officer and a Department of Veterans Affairs police officer. He also worked briefly in real estate. Court records show multiple domestic-violence allegations by his ex-wives, though no criminal charges have been recorded.
The incident has intensified scrutiny of ICE’s hiring and training processes. The agency has been recruiting heavily among military veterans and former law-enforcement personnel, a strategy that allows rapid onboarding with limited background checks, according to former Homeland Security officials. DHS has said it has recently added training modules on crowd control, high-risk vehicle stops, medical response and live-fire exercises.
Homeland Security Secretary Markwayne Mullin stated that officers involved in shootings are placed on administrative leave pending investigation. Federal inquiries into the Biddeford shooting remain ongoing.
