On July 13, 2026, Johan Sebastián Durán Guerrero, a 25-year-old Colombian immigrant to the United States, was shot and killed by David Brouillette, a United States Immigration and Customs Enforcement (ICE) officer during a traffic stop in Biddeford, Maine, United States. Durán Guerrero's car was rammed by an ICE vehicle while he circled an intersection incapacitated after his car was shot at five times; he was struck in the head and pronounced dead at the scene. ICE agents were executing a search warrant, though Durán Guerrero was not the target of the warrant. The incident occurred six days after the killing of Lorenzo Salgado Araujo in Houston, Texas, who was shot by ICE during another traffic stop, and it prompted ICE to suspend using traffic stops to carry out operations; President Donald Trump overturned the suspension a day after it was ordered. The Department of Homeland Security (DHS) and ICE defended the officer who opened fire, saying he was "fearing for public safety" when Durán Guerrero tried to flee. Members of Brouillette's family conducted several interviews with news outlets, saying he had a history of mental health issues, and alleged a history of domestic violence. Allegations of domestic abuse were reflected in family court records. Durán Guerrero's killing sparked several local protests in Biddeford and throughout Maine, and several politicians called on ICE to reform their tactics.
