AUGUSTA, Maine (AP) — David Brouillette, an Immigration and Customs Enforcement officer, shot and killed a Colombian man in Biddeford, Maine, earlier this week. Relatives of Brouillette have reported a history of mental health issues and violent behavior, stating he has struggled with these problems since childhood. They claim he has exhibited violent behavior towards women in his life and shared concerning messages he sent to family members.
The incident occurred on July 13, 2026, when Brouillette shot 25-year-old Johan Sebastián Durán Guerrero while he was in his car. The Department of Homeland Security stated that the vehicle attempted to flee, prompting Brouillette to discharge his weapon. Brouillette did not respond to requests for comment, but relatives indicated he claimed to have acted in self-defense.
Brouillette's ex-wife, Ashley, expressed disbelief when he informed her of his employment with ICE, given his mental health history. She recounted instances of physical violence during their marriage, including an incident where he allegedly threw boiling water at her while she held their child. Family court records reveal multiple allegations of abuse from his second ex-wife, who sought protection orders against him.
Brouillette reportedly has no criminal record in Maine, but court documents detail years of allegations of abuse. His oldest daughter described witnessing his volatility and expressed concern over his mental health. A relative indicated that Brouillette was diagnosed with severe bipolar disorder and attention deficit disorder as a child, and has faced significant mental health challenges throughout his life.
