Trenton Barker, 34, of Portland, pleaded guilty to arson for setting fire to debris near an ICE facility in South Portland on June 11, 2025, during a protest aimed at blocking ICE officers. Federal prosecutors said he threw a lit flare from his backpack, causing flames that were extinguished within minutes. He was arrested about an hour later after being identified by an officer who noticed black tape on his backpack. Barker, a forklift driver from Salem, admitted to the act and faces a mandatory minimum five-year sentence, with sentencing set for March 4, 2026. His state charges will be dismissed. He is one of 40 people charged in connection with federal offenses linked to protests at the facility, which began in June amid heightened immigration enforcement under President Trump.
