2 Felony Charges For Joliet Police Lt. Jeremy Harrison As He Appeals His Termination

JOLIET, IL — The Illinois State Police Division of Criminal Investigation announced on Facebook Wednesday afternoon that two felony charges are now on file at the Will County Courthouse for "former police officer" Jeremy Harrison, 50, of Plainfield as he faces allegations of misusing the city’s Flock system.

According to the state agency, in October of 2025, the Joliet city inspector general requested that ISP investigate Harrison, who was a lieutenant with the Joliet Police Department. The request was made after an allegation that Harrison had been using the Flock license plate reader system for personal benefit. After a thorough investigation, state police and the Illinois Appellate Special Prosecutor presented the case to a grand jury in Will County, and Harrison was charged with computer tampering and official misconduct, ISP said.

There is no additional information, and no booking photo was available, the Illinois State Police added.

Harrison Goes On Leave In July 2025

Joliet Patch previously reported that Harrison was put on paid leave from the Joliet Police Department in late July of 2025. Then, in late December, Police Chief Bill Evans announced his decision to fire Harrison, who has been a member of the Joliet police force for 26 years.

Harrison and his lawyer Michael Ettinger appealed the termination, and a final decision has yet to be made by the city's police and fire board, a five-member panel made up of appointments recommended by Mayor D'Arcy.

According to the Joliet Police chief's termination notice, in July 2025, "Lieutenant Harrison accessed the Joliet Police Department's Automatic License Plate Reader Database, known as 'Flock,' for a purpose not associated with law enforcement activities, but for personal purposes to track the location of a female officer.

"Specifically, Lieutenant Harrison accessed the Flock system on approximately eight occasions on or around July 2025 to search the personal license plate of a Joliet Police Officer ... and he conducted approximately 153 searches for (the female officer's) license plate. At the time of Lieutenant Harrison's Flock searches, the Joliet Police Department was not conducting any active police investigations into (the officer) and her vehicle was not associated with any active investigations."

Separately, the chief of police recommended Harrison's termination for additional violations of the Joliet Police Department's general conduct guidelines.

"On or about July 2025, Lieutenant Harrison entered false information into the Flock system to conduct the searches of (the officer's) ... license plate. Specifically, on various occurrences on or around July 2025, Lieutenant Harrison selected the reasons for the search in the Flock system as 'wanted,' 'stolen' and/or 'reckless,' or words to similar effect, when those selections were not the truthful and/or accurate reason for his searches of (the officer's) license plate. At the time of Lieutenant Harrison's Flock searches, the Joliet Police Department was not conducting any active police investigations into (the officer) ... and her vehicle was not associated with any active investigations.

"Based on the foregoing charges and specifications, the Chief of Police has terminated Lieutenant Harrison's employment with the Joliet Police Department," the Dec. 22 internal affairs memo furnished to Harrison reads.

"I don't think he violated any rules."During an interview in May, Ettinger, Harrison's lawyer, told Joliet Patch, "I don't think he violated any rules."
