Chicago — The former Chief of Police in the village of Summit, Ill., has been sentenced to three years in federal prison for corruptly accepting money from a local businessman to help facilitate the transfer of a liquor license.

A jury in U.S. District Court in Chicago in December 2025 convicted John Kosmowski of Lockport, Ill., of bribery conspiracy, bribery, and obstruction of justice. On Wednesday, U.S. District Judge Steven C. Seeger sentenced Kosmowski to three years in federal prison. 

Evidence at trial revealed that Kosmowski conspired with a Summit building inspector—William Mundy—to accept $10,000 from businessman Krzystof Hodurek in 2017. Kosmowski and Mundy accepted the money intending to be influenced and rewarded in connection with the transfer of a liquor license to another person. Kosmowski received a cash payment from Hodurek in 2017 and then gave Mundy a portion of it.

Mundy pleaded guilty prior to trial to bribery and tax offenses. He is awaiting sentencing. Hodurek pleaded guilty last year to a federal wire fraud charge in connection with an unrelated scheme to fraudulently obtain unemployment insurance benefits from the state of Illinois. As part of his guilty plea, Hodurek admitted to participating in the bribery scheme with Kosmowski and Mundy. Hodurek is awaiting sentencing.

The obstruction conviction against Kosmowski stemmed from a meeting he had with Mundy in which Kosmowski informed Mundy of the federal investigation into the bribe. During the meeting, Kosmowski sought to corruptly persuade Mundy to mischaracterize the purpose of the payment by falsely suggesting that it was a loan.

Kosmowski’s sentence was announced by Andrew S. Boutros, United States Attorney for the Northern District of Illinois, Marta Grijalva, Acting Special Agent-in-Charge of IRS Criminal Investigation in Chicago, and Ryan Whalen, Acting Special Agent-in-Charge of the Chicago Field Office of the FBI. 

“Defendant was a sworn law enforcement official who put personal profit over the public that he had a duty to protect,” Assistant U.S. Attorney Jared Hasten argued in the government’s sentencing memorandum. “Corruption by law enforcement officials strikes at the heart of government, eroding public confidence in those very officials that the public trusts to ensure their safety.”
