A former police chief in the village of Summit, Illinois, has been convicted by a federal jury in Chicago for bribery and obstruction of justice. The case centered on John Kosmowski, 57, of Lockport, who was found guilty after a seven-day trial in U.S. District Court.
According to evidence presented at trial, Kosmowski conspired with William Mundy, a building inspector for Summit, to accept $10,000 from a local businessman in 2017. The payment was intended to influence and reward them in connection with transferring a liquor license to another person. Kosmowski received the cash payment and shared part of it with Mundy.
Mundy pleaded guilty before the trial to bribery and tax offenses and is awaiting sentencing.
The obstruction charge against Kosmowski resulted from his meeting with Mundy after learning about the federal investigation into the bribe. During this meeting, Kosmowski attempted to persuade Mundy to misrepresent the purpose of the payment as a loan rather than a bribe.
U.S. District Judge Steven C. Seeger scheduled sentencing for March 27, 2026.
The conviction was announced by Andrew S. Boutros, United States Attorney for the Northern District of Illinois; Douglas S. DePodesta, Special Agent-in-Charge of the FBI’s Chicago Field Office; and Adam Jobes, Special Agent-in-Charge of IRS Criminal Investigation in Chicago. Assistant U.S. Attorneys Tiffany Ardam and Jared Hasten represented the government.
