Johan Sebastian Duran Guerrero was 25 years old, a Colombian national, and had legal authorization to work in the United States [1].

On July 13, in Biddeford, Maine, an ICE agent attempted a traffic stop. The car attempted to flee. The agent, David Brouillette, shot and killed him [1].

The Marshall Project reported the agent's record on July 25. Brouillette had been at ICE roughly eight months, having previously worked as a corrections officer and a Veterans Affairs police officer [1]. Court documents show two of his former wives had obtained protective orders against him alleging abusive behaviour [1]. One, asked whether she believed him capable of 'this level of extreme violence,' answered 'unequivocally yes' [1].

Those documents existed before he was hired.

The context around it is a hiring surge. ICE is planning to expand from about 10,000 agents to 22,000 within months [1]. The Associated Press, examining 40 officers, found three with prior misconduct lawsuits; a Massachusetts inquiry found more than 50 officers still employed after leaving previous jobs amid discipline [1].

None of that establishes what happened in the seconds before the shot in Biddeford, and this account does not claim to. What it shows is the shape of the risk an agency takes on when it doubles the number of people it arms - and what that risk looked like on one road in Maine on July 13 [1].
