ICE officer in Maine shooting has disturbing history of violence, family says

Earlier this week, Colombian national Johan Sebastián Durán Guerrero, 25, was gunned down by an ICE agent while behind the wheel of his car in Biddeford, Maine. The incident occurred in front of his 3-year-old daughter. ICE has since confirmed that Guerrero was not the target of the enforcement action underway when he was killed. ICE was surveilling another residence as Guerrero was leaving for work.

Department of Homeland Security has issued conflicting narratives about what led to the shooting. Initially they claimed Guerrero was trying to run over one of the agents, but they have since backed away from that claim. They now say Guerrero was attempting to flee and that the officer opened fire out of fear for “public safety”.

Video showing the shooting itself has not yet circulated publicly, but the officers involved were apparently equipped with body cameras. Ring doorbell cameras nearby captured the sound of six or seven shots ringing out. Then, footage captured by stationary cameras and bystanders captured the aftermath of the shooting. One shows the officers attempting to corral the car, as if the person behind the wheel had already lost consciousness and was not in control of the vehicle. Another vantagepoint then shows agents pulling the seemingly lifeless body of Guerrero out of the car and onto the pavement, where it lay for several hours.

ICE agent’s family speaks out

Family members of ICE agent David Brouillette have identified him as the agent responsible for killing Guerrero. DHS has not publicly identified the agent, but Brouillette’s family members say Brouillette admitted in phone calls that he had been the one who shot Guerrero. Both immediate family members and ex partners of Brouillette say he has a lengthy history of violence and mental illness. Family court records also reveal accusations of violence both towards his partner and children.

An immediate family member of Brouillette says he had mental health struggles starting in childhood. From a young age, he became enamored with law enforcement and the military. He participated in JROTC in high school but was initially rejected for military enlistment because of his mental health diagnoses. According to the family member, Brouillette’s recruiters encouraged him to discontinue his medication and reapply. He was eventually accepted and served in Afghanistan, which the family member said only worsened Brouillette’s mental condition.

Ashley Brouillette, one of Brouillette’s ex-wives and mother of at least one of his children, says Brouillette told her in late 2025 that he had been hired by ICE. Ashley said at the time she did not believe it given his extensive psychiatric history and assumed he was having a mental health episode. Around that same time, Brouillette sent Ashley a 3-minute long voice message saying that Ashley and other women and girls of her “bloodline” should have their throats slit.

Brouillette’s hiring at ICE renews serious concerns about the agency’s practices in vetting new hires. These concerns have been raised numerous times throughout Trump’s second administration as ICE has rushed to hire new agents.
