AP Exclusive: ICE officer in Maine shooting has history of violent behavior, family and records say

Key Points:

• David Brouillette, an ICE officer and Army veteran who shot and killed Colombian national Johan Sebastián Durán Guerrero in Maine, has a long history of severe mental health issues and violent behavior, according to his relatives.
• Family court records and relatives detail allegations of physical and verbal abuse by Brouillette against women and children in his life, including incidents of stalking, harassment, and violence, raising concerns about his fitness for law enforcement duties.
• Despite his troubled past and mental health diagnoses, Brouillette served in the military from 2007 to 2015, including deployment to Afghanistan, where relatives believe his emotional struggles worsened, before joining ICE amid President Trump's immigration crackdown.
• ICE has not publicly identified Brouillette or commented on his background but stated he has nearly a decade of federal law enforcement experience and required use-of-force training; his relatives say he claims the shooting was in self-defense.
• The case highlights questions about the Department of Homeland Security’s vetting processes during a period of rapid recruitment for immigration enforcement, as at least 10 people have died in encounters with immigration agents since 2017.
