An Immigration and Customs Enforcement (ICE) officer who shot and killed a Colombian man in Maine this week has a history of violent behavior, according to his relatives. David Brouillette, 37, is an Army veteran who has struggled with serious mental health issues since childhood, including manic bipolar disorder and attention deficit disorder.

History of Abuse

Brouillette’s relatives accuse him of attacking women in his life, including his ex-wives and daughters. One ex-wife shared a voicemail with the Associated Press in which Brouillette told her that someone should slit her throat. Brouillette’s oldest daughter, Madison, said she witnessed her father’s volatility and that he once told her he had been sitting on a tree stump with a gun to his head.

Brouillette’s history of abuse is documented in hundreds of family court records, which detail allegations of physical and verbal abuse raised by his second ex-wife on behalf of herself and his daughters. The records show that Brouillette was granted a temporary protective order in 2021 after his ex-wife alleged that he had stalked and harassed her and physically and verbally abused his daughter.

Law Enforcement Career

Brouillette enlisted in the Army in 2007 and was deployed to Afghanistan from 2012 to 2013. After leaving the Army, he worked as a real estate sales agent in Maine. In late 2025, he joined ICE, despite his history of mental health issues and violent behavior.

ICE spokesperson Lauren Bis said that the agency will not confirm or deny attempts to dox its law enforcement officers, but added that Brouillette has nearly a decade of federal law enforcement experience and has received required training, including use of force training.
