New details are emerging about the ICE agent who shot and killed 25-year-old Johan Sebastián Durán Guerrero on Monday.David Brouillette has a history of violent and abusive behavior, his relatives told the Associated Press, including attacks on the women and girls in his life. His first ex-wife, Ashley Brouillette, said that she divorced him after he became violent with her while she was pregnant with their daughter.In one instance, she told the AP, he threw boiling water at her while she was holding their daughter, which her mother, Avis Collins, also confirmed. In court records, another of Brouillette’s ex-wives also alleged years of physical and verbal abuse against her and her daughters. The AP did not identify her because she fears retaliation.Brouillette’s second ex-wife said he stalked and harassed her, and engaged in physical and verbal abuse against his daughter, forcing them to seek temporary protection orders. Brouillette allegedly tackled his teenage daughter, smashed spaghetti in her hair, and one in instance, dragged her around the house while she was crying.“Dave needs counseling or something for his PTSD & depression,” the ex-wife wrote while applying for a temporary protective order on behalf of Brouillette’s teenage daughter, which a judge granted in 2021.Brouillette’s oldest daughter, Madison, also told the AP about her father’s mental health issues.“I saw my dad struggle with a lot of things,” she said, recalling one instance where she came home from school and he told her that he had sat on a tree stump holding a gun to his head. “If you don’t really, truly take care of yourself, there’s no way you can protect other people. And with my dad, he never wanted to get help.”One relative anonymously told the AP that Brouillette was diagnosed with attention deficit disorder and severe bipolar disorder as a kid, which Ashley Brouillette confirmed. That relative said that David Brouillette was “extremely mentally ill,” attempting suicide when he was 12 years old and having to go to the hospital. His ex-wife Ashley shared a three-minute voicemail with the AP from last winter where he told her that he thought someone should slit her throat.In that message, sent around the time he joined ICE, he called her “disgusting” and said that she and other women and girls in her “bloodline” should die.“And all of you should have your f—king throats cut,” Brouillette’s voicemail said. “Yeah, you should. Am I threatening that I’m gonna do that? Nope. Nope. But do I think that you should have your f—king throats cuts? Or should have had them cut? Yep.”Brouillette reached out to Ashley and his daughter Madison after the shooting, telling them it was justified and that Durán Guerrero tried to run him over with a car. In those calls, he told his ex-wife to lie for him and to cover for his “character.” Based on his history, that was a lost cause.
