A Chicago man has been sentenced to 20 years in federal prison for robbing three banks at gunpoint. In 2020 and 2021, Christopher Porter, 53, robbed a bank in Evergreen Park, Ill., and two banks in Chicago.  In all of the robberies, Porter pointed a gun at tellers and customers.  In the third robbery, Porter put a customer in a headlock, pointed a gun at his head, and pinned him against a wall. A federal jury in 2022 convicted Porter of all three robberies, as well as a firearm charge.  U.S. District Judge Sharon Johnson Coleman imposed the sentence on Thursday during a hearing in federal court in Chicago. The sentence was announced by Morris Pasqual, Acting United States Attorney for the Northern District of Illinois, and Douglas S. DePodesta, Special Agent-in-Charge of the Chicago Field Office of the FBI.  Valuable assistance was provided by the Cook County Sheriff’s Office. “Defendant terrorized innocent bank tellers and customers,” Assistant U.S. Attorneys Thomas P. Peabody and Paige A. Nutini argued to the Court at sentencing.  “His short spree of bank robberies was serious, violent, criminal conduct.”
