The U.S. Immigration and Customs Enforcement agent identified as David Brouillette, 37, admitted to the shooting death of Johan Sebastian Duran Guerrero, 25, during a phone call with his ex-wife shortly after the incident. Guerrero, who immigration advocacy groups state had authorization to work in the U.S. and a Social Security number, leaves behind a wife and daughter. The ICE agents involved were not equipped with body cameras, and federal officials have refused to release information about the officer, while state officials are conducting a parallel investigation. The incident has prompted ICE to temporarily halt most traffic stops and has drawn condemnation from the Colombian president and calls for reform from Maine’s congressional delegation and governor.

The recent fatal shooting of a man in Biddeford by a U.S. Immigration and Customs Enforcement (ICE) agent has taken a significant turn with the identification of the agent by his ex-wife. This development has brought the agent, David Brouillette, into the spotlight, revealing details about his past and his alleged actions following the incident.
The ex-wife, Ashley Brouillette, identified David Brouillette, 37, as the ICE agent who fatally shot 25-year-old Johan Sebastian Duran Guerrero. She recounted a phone call with her ex-husband shortly after the shooting, during which he reportedly admitted to firing the shots. This confession, shared with the Portland Press Herald, paints a chilling picture of the immediate aftermath.
During that crucial conversation, Ashley Brouillette stated that her ex-husband asked her to “lie for him” and “cover for his character.” She described him as being “unusually calm” during this exchange, a detail that has raised further questions about his demeanor and state of mind.
David Brouillette was reportedly a new recruit with ICE when the shooting occurred. He fatally shot Guerrero in his vehicle around 7 a.m. at the intersection of Pool and Hill streets. Information surfaced earlier that the ICE agent involved had been hired that year, but Brouillette’s identity was not officially confirmed until recently.
Employment records obtained by the Bangor Daily News shed light on Brouillette’s professional history. Before joining ICE, he had stints with the Togus VA Police Department and as a Maine prison guard. His time with the Togus VA Police Department began in March 2017, though the exact end date of this employment is unclear.
He also appears to have considered a career in real estate, obtaining a license in April 2025 that later became inactive in December of the same year. This brief foray into real estate suggests a period of professional transition or exploration.
Prior to his work at Togus, Brouillette spent less than a year as a corrections officer at the Maine Correctional Center in Windham, working there from November 2015 to August 2016. His career path, therefore, includes experience in law enforcement and corrections.
The Press Herald also reported on Brouillette’s involvement with the volunteer fire department in Manchester, Maine, where he resides. He reportedly had two brief stints with the department but was “removed” for actions such as shouting and refusing to follow a supervisor’s orders. These past disciplinary issues have added another layer to the public’s perception of his character.
Adding to the complexity of the situation, the ICE agents involved in the shooting were not equipped with body cameras. This is despite Congress approving $20 million in funding for such equipment this year. The absence of direct video evidence of the moments leading up to the shooting has left a critical gap in the official account of events.
The lack of body camera footage raises significant questions about accountability and transparency, particularly given the substantial funding allocated for this technology. It leaves the public to rely on witness accounts and the statements of individuals involved, including Brouillette’s ex-wife.
The circumstances surrounding Brouillette’s past, including his departure from the fire department and his alleged request to his ex-wife to “lie for him,” have fueled considerable public commentary and scrutiny. Many have expressed outrage and disappointment, questioning his suitability for law enforcement roles and criticizing the broader practices and oversight within ICE.
The fact that an ex-wife is the one identifying the agent and speaking out about his actions has been noted by many as a powerful and significant development. It suggests a profound disconnect between Brouillette’s public persona and his private life, as relayed by someone who knew him intimately.
The narrative emerging is one of a former law enforcement officer with a documented history of disciplinary issues, now implicated in a fatal shooting while working for ICE. The identification by his ex-wife, coupled with her account of his request for her to cover for him, has amplified public interest and concern surrounding this tragic event.
