Editor’s note: The second ex-wife of David Brouillette released a statement on Saturday. Read more: Second ex-wife of ICE agent who shot man in Biddeford recounts history of violent behavior

---

The federal immigration agent who shot and killed a 25-year-old Colombian man in Biddeford has been identified as David Michael Brouillette.

Brouillette, who is 37 and lives in Manchester, was identified by an ex-wife as the Immigration and Customs Enforcement agent who shot Johan Sebastián Durán Guerrero on Monday.  

Ashley Brouillette told the Portland Press Herald in a phone interview Thursday afternoon that her ex-husband called admitting to the shooting and defending his actions. The Press Herald, the first news outlet to report David Brouillette’s identity, reviewed a screenshot of incoming calls that Ashley Brouillette said she received from her ex-husband via his current wife’s Facebook account on Wednesday.

“He was asking me to lie for him and to cover for his character,” Ashley Brouillette said. “I told him that I was not going to lie for him. And then he tried to say that it was a justified shooting because the guy tried to hit him with his car.”

She said she has seen videos of Brouillette on the scene of the shooting and told him: “Nowhere in there does it show that this man charged at you with a car.”

“In his head it’s justified. He’s unusually calm about it,” she said.

David Brouillette has held multiple jobs in law enforcement and public safety in Maine. He’s also a licensed real estate agent and a veteran.

He has not responded to several requests for comment and a cellphone number for him was disconnected Thursday afternoon. An attempt to reach Brouillette at his home was unsuccessful. His address is down a long dirt road with a no trespassing sign.

Ashley Brouillette told a reporter that she wanted to speak publicly because she had previously reported concerns to his superiors in the military about David Brouillette’s mental health.

Ashley Brouillette also described to the Press Herald her ex-husband’s abusive behavior during and after their marriage. She said she does not live in Maine and that she avoids contact with him, but he still reaches out.

She provided a voicemail from a man with slurred speech, which she said Brouillette left in the fall of 2025. He disparages her several times, asserts he’s in a better financial position than her, and states “you should have your (expletive) throats cut, yup, you should.”

“Am I threatening that I’m going to do that?” the man said. “Nope. But do I think you should have your (expletive) throat cut or should have them cut? Yep.”

A story published Thursday evening by The Associated Press described David Brouillette’s history of violent behavior, based on interviews with Ashley Brouillette, their 18-year-old daughter Madison Brouillette and an estranged relative.

That relative, whose name the AP withheld, said Brouillette had been diagnosed with manic bipolar disorder and attention deficit disorder as a child and was rejected by military recruiters the first time he applied because of these diagnoses. The relative said Brouillette was admitted a year later after going off of his medication.

Madison Brouillette told the AP that her father called her on Wednesday and said he shot and killed Guerrero.

SHOOTING IN BIDDEFORD

On Monday, news broke that a federal agent shot Guerrero in Biddeford as U.S. Immigration and Customs Enforcement agents were surveilling a property nearby. Guerrero was living in Biddeford with his partner and young daughter.

The Department of Homeland Security has refused to identify David Brouillette and agents involved in other shootings, including in Texas, where an ICE agent shot Lorenzo Salgado Araujo less than a week before Guerrero’s death. 

When provided with Brouillette’s name, a spokesperson for ICE said the officer “in question has nearly a decade of federal law enforcement experience with required training.”

The agency said in a statement Thursday that federal authorities “will never confirm or deny attempts to dox our law enforcement officers.”

“Doxxing our officers puts their lives and their families in serious danger,” the ICE spokesperson said in a statement. “Now, thanks to the malicious rhetoric of sanctuary politicians, they are under constant threat from violent agitators.”

A witness to the Biddeford shooting, Daniel Boucher, told the Press Herald he saw an agent on scene who matched Brouillette’s description. Three people who worked with Brouillette at the Manchester Fire Department also confirmed that Brouillette was pictured in images they saw from video of the scene in Biddeford after the shooting.

ICE has said it “was conducting targeted surveillance on the last known address of an illegal alien with a final order of removal.” When the driver attempted to flee, according to the agency, a federal officer discharged his weapon. U.S. Sen. Angus King’s office said on Monday that the head of DHS has told him the man shot was not the intended target of the warrant.

By Wednesday morning, the website ICE List announced that it had determined Brouillette was the shooter, citing two people who knew him personally and came forward independently. The site — a public database of ICE officers run by a man living in the Netherlands and hundreds of volunteers, who receive and vet tips — does not name either individual, nor did its staff respond to a request for comment. 

MILITARY, LAW ENFORCEMENT BACKGROUND

ABC News and The Atlantic reported on Tuesday that the agent was hired by ICE earlier this year and that he had worked for the Department of Veterans Affairs.

Brouillette was hired as an officer for the Togus Police Department at the VA in 2017, according to records from the Maine Criminal Justice Academy. He was still working there in 2021, according to court records from a legal dispute with another ex-wife, whom he married after separating from Ashley Brouillette.

David Brouillette is a U.S. Army veteran and had been receiving disability benefits through the VA, according to the court records.

Ashley Brouillette said they both attended ROTC while they were growing up together in Maine. They married when she was 18 years old and divorced two years later, she said.

David Brouillette attended high school in Gardiner, and was also a member of the Kennebec Valley Young Marines color guard, according to newspaper archives.

Brouillette served in the Maine National Guard from 2007 to 2010 and was honorably discharged as a private first class, according to a spokesperson for the organization. An Army spokesperson confirmed that while at the Maine National Guard, Brouillette worked as a medical logistics specialist before serving as a quartermaster and chemical equipment repairer.

The Army spokesperson also confirmed that Brouillette had served in the U.S. Army from 2010 to 2015 as a human intelligence collector. He deployed to Afghanistan from May 2012 to February 2013. He left the Army as a sergeant, according to the spokesperson.

Some of his positions have been brief.

He worked as a corrections officer at the Maine Correctional Center in Windham in 2015 and resigned a year later, according to public employment records and documents from the Maine Criminal Justice Academy. The documents don’t state the reason for his resignation. The Maine Department of Corrections did not respond to a request for records Thursday.

Public employment records also show Brouillette worked for the Maine Department of Health and Human Services from 2019 to 2020. A spokesperson for the department confirmed Brouillette had voluntarily resigned after eight months in his position as a human services enforcement agent within the Division of Support Enforcement and Recovery.

Brouillette told a judge, during a matter involving child support payments, that he was working as a truck driver before January 2025 when he said he had to resign due to health concerns. Brouillette had also reported plans to work as an independent contractor and that he was doing real estate work, according to a judge’s order.

In 2024 and 2025, he was a volunteer firefighter in Manchester. He worked there for two short stints across a matter of months before he was “removed” after several spats with department leadership, according to former and current staff. His tenure included a shouting match, staff said, and refusal to follow superiors’ orders.

A Maine-based criminal background check did not reveal any criminal convictions against Brouillette. A review of online state court records showed only a traffic infraction.

Brouillette appears to be the second Maine resident and federal immigration officer who has shot someone during enforcement operations. 

Last year, Charles Exum, an agent for U.S. Customs and Border Protection, shot and injured a woman in Chicago. Exum was identified through court records in a criminal case against the woman.

Federal agents accused her of trying to hit them with their car. Prosecutors dismissed the case after her attorney questioned the agents’ credibility, highlighting texts Exum had sent to other officers, bragging about his marksmanship.
