The vetting process of an Immigration and Customs Enforcement (ICE) officer involved in the fatal shooting of a Colombian man in Maine is under internal review, following revelations from the victim’s family regarding the officer’s mental health history and past violent behavior. The officer, identified as Army veteran David Brouillette, is at the center of scrutiny as officials examine whether proper procedures were followed before his hiring.

Tom Homan, President Donald Trump’s top border advisor, said on Sunday that if the allegations are confirmed, the officer should not have passed the vetting process. “There’s several things under review,” Homan told CNN, noting that both the officer’s training and vetting are being examined by ICE’s internal affairs.

The incident, which occurred on July 13 near Biddeford, Maine, involved the shooting death of 25-year-old Johan Sebastián Durán Guerrero while he was in his vehicle close to his home. The case has intensified questions regarding the Department of Homeland Security’s approach to recruiting, training, and deploying a surge of ICE officers amid the Trump administration’s immigration enforcement efforts.

Concerns about enforcement tactics have mounted after a series of recent deaths connected to ICE operations. A week prior to the Maine shooting, ICE agents in Houston fatally shot Lorenzo Salgado Araujo during a vehicle chase. The shooting, which happened in July, was witnessed by Salgado’s coworkers and family members. Earlier in the year, two protesters in Minneapolis, Renee Good and Alex Pretti, were also killed by federal agents during demonstrations against ICE, further fueling public outcry.

Following the fatal shooting in Maine, Homeland Security Secretary Markwayne Mullin temporarily paused ICE vehicle stops. However, President Trump quickly reversed this decision, emphasizing the need to continue such stops to advance the administration’s goal of deporting immigrants lacking legal status.

In response to these incidents, acting ICE Director David Venturella has issued new directives aimed at increasing transparency during enforcement actions, mandating the use of body-worn cameras for vehicle stops. “Right now, on all vehicle stops, there’s at least one body camera on-site to record the entire event,” Homan said, adding that the new requirement is intended to ensure comprehensive video documentation.

Despite these measures, some members of Congress remain unconvinced that the department’s training and operational tactics are sufficient. The Trump administration aimed to deport 1 million immigrants annually—a target that has not been met despite heightened enforcement that has often escalated tensions in communities across the United States.

Since the launch of the broader deportation campaign, at least 10 deaths have occurred during confrontations with immigration enforcement officers. The internal review of Brouillette’s conduct and background continues amid ongoing investigations into these cases. The Department of Homeland Security did not immediately comment on the status of its review.
