Jeffrey Tobolski, the former mayor of the west-suburban village of McCook and a onetime Cook County commissioner, was sentenced Monday to four years in federal prison for shaking down business owners and filing a false tax return. The punishment came five years after Tobolski pleaded guilty and agreed to cooperate with a broad federal corruption investigation. Prosecutors said Tobolski, 60, extracted more than $250,000 in cash, gifts and services from businessmen seeking liquor licenses or other municipal approvals, even using the town’s police chief as a courier. He also under-reported his income by at least $66,000, including bribe money, on his 2018 tax return. At the hearing in Chicago’s Dirksen U.S. Courthouse, Chief U.S. District Judge Virginia Kendall described Tobolski as a “Jekyll and Hyde” figure who abused public power “fueled by alcohol.” The Justice Department had asked for 5½ years, citing the scope of the pay-to-play scheme, while the defense sought leniency, pointing to Tobolski’s cooperation that helped secure convictions of other officials. The sentence caps one of the last cases stemming from a 2019 FBI sweep that has snared nearly a dozen suburban politicians and operatives over red-light-camera contracts and other kickback arrangements. Tobolski, who resigned from office in 2020, told the court he had “added to the ever-increasing distrust in elected officials” and said the investigation forced him to confront “lies and deceit” that had defined his tenure.
