The ICE agent who fatally shot Joan Sebastian Guerrero during a traffic stop in Maine had previously been accused by two former wives of violent, threatening and abusive behavior, according to interviews and court records reviewed by The Washington Post.
The allegations are disturbing.
One former wife said David Brouillette once threw boiling water at her while she was holding their young daughter.
She also alleged that he kicked open a bathroom door while she was showering and pointed a gun at her.
Another former wife described a pattern of anger and physical intimidation in court filings, including claims that Brouillette screamed at a child, dragged her from bed by her feet and dumped a plate of spaghetti over her head.
The accusations were not reported as criminal convictions, and their existence does not prove that Brouillette acted unlawfully when he shot Guerrero.
But the disclosures are now raising urgent questions about how a man with such serious allegations in his background continued obtaining law-enforcement positions involving firearms.
Guerrero, a Colombian national, was fatally shot Monday during an immigration traffic stop in Biddeford, Maine.
Authorities later identified Brouillette as the ICE agent involved.
The precise circumstances of the encounter remain under investigation. Publicly available reporting has not yet established whether the shooting was legally justified, and Brouillette is entitled to due process.
Still, Guerrero’s death sparked protests and intensified criticism of ICE tactics, particularly because it was one of two fatal shootings involving immigration officers during traffic stops in a single week.
ICE briefly suspended such stops after the incidents, according to reports.
President Donald Trump then called for the policy reversal to be undone, renewing concerns that immigration enforcement would continue under heightened pressure while questions about officer conduct remained unanswered.
Against that backdrop, the allegations concerning Brouillette’s personal history have taken on new significance.
Ashley Brouillette, one of his former wives, told The Washington Post that she had feared for years that he might eventually harm someone.
She described their marriage as brief but said his aggressive conduct continued after it ended in 2009.
In one alleged incident, she said Brouillette threw boiling hot water on her while she was holding their daughter.
In another, she claimed he forced open a bathroom door and aimed a firearm at her while she was in the shower.
Those claims are Ashley Brouillette’s account and have not been established in the reporting as findings from a criminal trial.
But they depict behavior that would ordinarily raise serious concerns in any background review for an armed federal position.
Ashley said she could not understand how her former husband continued finding work that gave him access to firearms.
Her concern became even more pointed after Guerrero’s death.
The second former wife, Lucinda Brouillette, reportedly described similar conduct in family-court documents.
According to the Post, she alleged in 2021 that Brouillette had grown increasingly impatient, aggressive and angry toward his daughter from his first marriage.
The filings reportedly accused him of insulting the girl, screaming at her, dragging her out of bed by her feet and dumping an entire plate of spaghetti onto her head.
On Saturday, Lucinda issued a direct public statement about whether she believed her former husband was capable of extreme violence.
Her answer was unequivocal.
“If you were to ask me whether I believe David Brouillette is capable of this level of extreme violence, my answer is unequivocally yes,” she said.
“That belief is not based on speculation, but on my own lived experiences over many years.”
Her statement represents her assessment based on their relationship. It is not proof of what happened during the traffic stop.
Still, the pattern alleged by both women creates a difficult question for ICE and every agency that previously employed Brouillette:
What did officials know, and when did they know it?
Law-enforcement agencies typically conduct background investigations before hiring officers. Those reviews may include criminal records, employment history, references, financial information and previous allegations of misconduct.
Family-court filings and accusations made during divorces do not automatically disqualify someone from employment.
Allegations can be contested, incomplete or made in highly adversarial circumstances.
But claims involving guns, boiling water, physical aggression and threats toward family members would appear serious enough to warrant close scrutiny.
The issue is not whether every accusation should be automatically accepted as true.
It is whether the allegations were discovered, investigated and weighed before Brouillette was authorized to carry a firearm and exercise federal power over the public.
Guerrero’s death has also renewed demands for an independent investigation.
Critics have expressed alarm over separate reporting that FBI officials may have been told to reduce their involvement in confrontations involving immigration agents, potentially leaving ICE’s own investigative structures with greater control.
The Justice Department and Department of Homeland Security have denied that their investigative relationship changed.
But the perception that ICE could effectively examine its own personnel has become even more troubling in light of Brouillette’s alleged background.
Independent scrutiny matters because officer-involved shootings often require examination of more than the final seconds.
Investigators may consider training, disciplinary history, prior complaints, judgment under pressure and whether an officer followed agency policy.
Previous domestic-abuse allegations do not automatically determine whether a later shooting was justified.
But they can be relevant to questions about temperament, hiring and institutional oversight.
Guerrero’s family and supporters are still awaiting a full account of why the traffic stop ended in death.
Protesters gathered at a candlelight memorial in Maine, where a handwritten sign displayed Guerrero’s name.
For them, the case is no longer only about a single encounter.
It has become part of a wider debate over aggressive immigration enforcement, deadly force and whether federal agents are being adequately screened and held accountable.
Brouillette has not been convicted of abusing either former wife based on the information presented in the report.
Nor has a court yet concluded that the shooting of Guerrero was criminal.
Those distinctions are essential.
But the newly reported allegations cannot simply be dismissed as irrelevant.
Two former spouses independently described a man they said could be aggressive, threatening and violent.
One said she feared he would eventually hurt someone.
Years later, he became the federal agent identified in a fatal shooting.
That does not settle the case.
It makes the need for answers impossible to ignore.
