The federal immigration agent who fatally shot a man in Biddeford last week is in protective custody of the government, according to court records reported by the Portland Press Herald on Friday.
David Brouillette, 37, is believed to be the agent who shot 25-year-old Johan Sebastian Duran Guerrero during a traffic stop on July 13.
Federal authorities have not yet identified the agent who fired the shots, but his ex-wife identified him to the Press Herald shortly after the shooting, claiming that Brouillette admitted to firing the shots and asked her to “lie for him” and to “cover for his character,” describing him as “unusually calm.”
Brouillette was a new recruit when he fatally shot Duran Guerrero in his vehicle about 7 a.m. at the intersection of Pool and Hill streets in the York County city. The Atlantic magazine earlier reported that the ICE agent who shot Duran Guerrero was hired this year.
Several of his close relatives told The Associated Press that Brouillette struggled with serious mental health problems since early childhood and a history of terrifying and violent behavior.
Employment records obtained by the Bangor Daily News show that Brouillette used to work for the police department that safeguards the Togus VA Medical Center campus and spent a brief stint as Maine prison guard before that.
The Togus VA Police Department hired Brouillette in March 2017, according to a notice of employment record filed with the Maine Criminal Justice Academy, which oversees the certification of law enforcement officers in the state. It is unclear when he left that job. He appears to have contemplated a career in real estate last year, according to a license he obtained in April 2025 that went inactive in December.
Prior to working at Togus, he worked for less than a year as a corrections officer at the Maine Correctional Center, a state prison in Windham, records show. He worked there from Nov. 30 2015 to August 2016.
An ICE spokesperson initially claimed that Duran Guerrero, who was from Colombia, was in the country illegally and had a final removal order against him. But Homeland Security Secretary Markwayne Mullin, who previously suggested Guerrero had “weaponized” his white Kia, told U.S. Sen. Angus King that Duran Guerrero wasn’t actually the target of the agents’ administrative warrant.
Two immigrant advocacy groups here, Maine Immigrants’ Rights Coalition and Presente! Maine, said in a joint statement that Duran Guerrero, who leaves behind a wife and young daughter, had authorization to work in the United States and had been issued a Social Security number.
Federal officials said the ICE agents weren’t equipped with body cameras, for which Congress approved $20 million in funding this year, and no other video evidence has emerged of the shooting or the events that preceded it.
