David Brouillette, an ICE officer, fatally shot 25-year-old Colombian man Joan Sebastián Durán Guerrero during a vehicle stop in Biddeford, Maine on July 13 [1]. Although the Department of Homeland Security has not officially confirmed Brouillette’s identity, multiple news outlets have named him as the officer involved [1, 2, 3].

Brouillette faces serious allegations of abuse from two ex-wives who claim a pattern of intimidation, manipulation, and violence [1]. Relatives also told the Associated Press that he has a history of mental health struggles and violent behavior [2, 3]. "If you were to ask me whether I believe David Brouillette is capable of this level of violence, my answer is unequivocally yes," said ex-wife Lucinda Brouillette [1].

Tom Homan, former Trump administration border czar, said on July 26 that if these allegations are true, Brouillette should never have passed vetting. "No, if those … are facts … I don’t think he should ever have cleared vetting," Homan said on CNN [1]. He confirmed the vetting process and officer training are under internal review by ICE's internal affairs division [1, 3].

In response to the shooting, Homeland Security Secretary Markwayne Mullin temporarily ordered a pause on ICE vehicle stops for immigration enforcement. However, President Trump quickly reversed this and directed that stops resume shortly afterward [2, 3]. Acting ICE Director David Venturella mandated that all ICE officers use body cameras during vehicle stops to record interactions moving forward [3]. "Right now, on all vehicle stops, there’s at least one body camera on site to record the entire event," Venturella said [3].

Democrats and some lawmakers have called for broader reviews of DHS hiring, vetting, training, and enforcement tactics following the shooting [1, 3]. The internal review will investigate how vetting failed and whether changes in training are needed [2, 3].

The agency’s internal affairs is expected to complete its investigation in the coming weeks. Meanwhile, ICE officers will continue vehicle stops with body cameras mandated by the recent directive [3].
