Wilker Miguel Gutiérrez Sierra, 23, was arrested in February 2024 in Chicago on charges of attempted murder, robbery, and aggravated battery after allegedly assaulting a stranger on a train. He pleaded not guilty and was on electronic monitoring awaiting trial when ICE agents arrested him on the street in five black trucks in February 2025. Three days later he was deported to CECOT prison in El Salvador on March 15, 2025, removing him from the criminal justice system before his case could be resolved.
