ICE agent David Brouillette’s violent history highlighted after fatal shooting of Colombian man in Maine

On July 14, ICE agents conducting a traffic stop in Biddeford, Maine, shot and killed 25‑year‑old Colombian national Johan Sebastián Durán Guerrero, who was driving with his three‑year‑old daughter. The victim was not the target of the operation and had a valid work permit.

The officer identified by relatives and public records as David Brouillette, a 37‑year‑old Army veteran, has a documented history of violent behavior and serious mental‑health issues, including childhood bipolar disorder, multiple protection orders, and incidents of domestic abuse. His ex‑wife Ashley Brouillette told the Associated Press that he “is a danger to society” and questioned how he obtained a badge and firearm.

The shooting revives scrutiny of ICE’s rapid hiring surge under the Trump administration, which added roughly 12,000 agents in early 2024. Senate leaders have cited the case as evidence that the agency expanded without adequate vetting. Colombian President Gustavo Petro condemned the killing as an “assassination” of a Latin American citizen and called for swift legal action.

Family members, including Durán’s partner Karolina Rojas, have spoken publicly about the personal loss and demanded a thorough investigation. ICE maintains the vehicle attempted to flee and the officer fired in self‑defense, while the Department of Homeland Security has declined to confirm details about the officer’s identity or background checks.
