In a compelling legal development, a Chicago resident has filed a lawsuit against three police officers, alleging violations of his Fourth Amendment rights. Kenneth Deandre Williams Jr. lodged the complaint in the United States District Court for the Northern District of Illinois on November 11, 2025, accusing Jonathan Mondragon, Jonathan Hernandez, and Crystal Moreno of unlawful search and seizure.

The case centers around an incident that occurred on July 8, 2024. According to the complaint, Williams was waiting at a bus stop near 76th and Cottage Grove Avenue in Chicago when he boarded a Chicago Transit Authority bus. Shortly after boarding and paying his fare, the bus was stopped by the defendants—officers from the Chicago Police Department—who entered the vehicle and approached Williams. The plaintiff alleges that these officers conducted a search of his person without finding any contraband or having reasonable suspicion or probable cause to justify their actions.

Williams contends that this encounter constituted an unreasonable seizure and search under the Fourth Amendment of the United States Constitution. He claims that as a result of this interaction with law enforcement, he suffered emotional distress and financial harm. The complaint further accuses the officers of ignoring Williams’ requests for their names, badge numbers, and a stop receipt before they exited the bus.

The lawsuit is brought under 42 U.S.C. § 1983, which provides recourse for individuals whose constitutional rights have been violated by someone acting under state authority. Williams argues that his rights were infringed upon when he was seized without proper justification and searched unlawfully by officers Mondragon, Hernandez, and Moreno.

In seeking justice through this legal action, Williams is requesting several forms of relief from the court. These include general damages for harm suffered due to the defendants’ actions, special damages related to specific losses incurred as a result of this incident, attorney fees associated with pursuing this claim, as well as punitive and exemplary damages intended to punish and deter similar conduct in the future. Additionally, he seeks compensation for costs incurred during litigation and any other awards deemed appropriate by the court.

Representing Kenneth Deandre Williams Jr., attorney Peter T. Sadelski from Ed Fox & Associates Ltd., based in Chicago, has formally demanded a jury trial to resolve these issues. The case has been assigned Case No. 25-cv-13841 within the jurisdiction where these events transpired.
