A federal jury in Chicago has convicted John Kosmowski, the former Chief of Police for the village of Summit, Illinois, on charges of bribery conspiracy, bribery, and obstruction of justice. The verdict followed a seven-day trial in U.S. District Court.
Kosmowski, 57, from Lockport, Illinois, was found guilty after evidence showed he conspired with William Mundy, a Summit building inspector, to accept $10,000 from a local businessman in 2017. The payment was intended to influence the transfer of a liquor license to another individual. According to prosecutors, Kosmowski received the cash and later shared part of it with Mundy.
Mundy had previously pleaded guilty to bribery and tax offenses and is awaiting sentencing.
The obstruction charge resulted from a meeting where Kosmowski told Mundy about the federal investigation into the bribe and attempted to persuade him to mischaracterize the payment as a loan.
Sentencing for Kosmowski is scheduled for March 27, 2026 by U.S. District Judge Steven C. Seeger.
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 are representing the government.
