A shooting death in Biddeford, Maine has triggered fresh scrutiny of Immigration and Customs Enforcement hiring practices, with Democratic lawmakers demanding answers after reports surfaced about the officer's alleged history of violent behavior.
The victim, Joan Sebastián Durán Guerrero, a 25-year-old Colombian man, was killed on July 13. News outlets including the Associated Press, NPR, and the Portland Press Herald identified the officer involved as David Brouillette based on information from his family members. Those same reports alleged Brouillette had a history of mental health issues and had engaged in violent and threatening conduct toward his ex-wife.
The scrutiny intensifies a broader controversy within ICE. Guerrero's death came just days after another ICE officer fatally shot Lorenzo Salgado Araujo in Texas, and two additional ICE-related deaths occurred that same week, prompting calls for independent investigations of the Department of Homeland Security.
Mississippi congressman Bennie Thompson, the top Democrat on the US House homeland security committee, said the officer's alleged violent background raised fundamental questions about the agency's vetting process. "The officer's alleged violent history directly calls into question the supposed vetting and training ICE does of its recruits," Thompson told the AP. "This senseless tragedy must be investigated, and the officer responsible should be taken off our streets and face justice for his actions."
Senate Democratic leader Chuck Schumer attacked the Trump administration for what he characterized as reckless expansion of the ICE workforce. The administration hired 12,000 agents rapidly to support mass deportation operations without proper screening, Schumer argued on social media. "The president and his Republican allies then gave this rogue agency vast power and no accountability," he said, contending that neither Trump nor his party can "disown the deadly consequences" of that approach.
Reports indicated that Brouillette left a threatening voicemail for his ex-wife, Ashley, in late 2025, around the time he joined ICE. In the recording aired by NPR, he referenced cutting her throat. Brouillette was described as a military veteran and former police officer before joining ICE in 2025.
A Department of Homeland Security spokesperson declined to confirm or deny the officer's identity, citing protection of law enforcement personnel. However, the spokesperson claimed the officer involved had nearly a decade of federal law enforcement experience. The Department of Justice and DHS have not yet publicly identified Brouillette or released details about the circumstances of the shooting.
Guerrero, who leaves behind a three-year-old daughter and her mother, his partner, was the third person shot to death by a federal immigration officer since Trump's second presidency began in early 2025.
Author James Rodriguez: "The speed at which ICE expanded its ranks and the apparent lapses in screening workers with violent histories suggest an agency operating on crisis footing rather than sound judgment."
