Criminal Cases in the Circuit Court of Kane County
A criminal case from Carpentersville is filed in the Circuit Court of Kane County, and the court file, kept by the Circuit Clerk, is the record of it that the public may see.
For Kane County, SearchSystems opened and checked the court records page for the county at cic.countyofkane.org/pages/online-court-records.aspx (page title: Online Court Records), which answered when SearchSystems opened it on September 23, 2026.
Illinois has no single public index of every trial court case; each court's records are looked up through that court.
The Illinois Criminal History and Your Own Copy
Illinois is one of the states that lets anyone look up another person's statewide criminal history: conviction information is public under the Uniform Conviction Information Act, through the Illinois State Police. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it.
To see your own record, the route is a name-based or fingerprint-based request to the Illinois State Police. The state page SearchSystems verified for it is at isp.illinois.gov/BureauOfIdentification/MyRecord.
Arrest Records Kept Locally in Carpentersville
The Kane County Sheriff's Office and the agency that reports for Carpentersville (filed by the FBI as Carpentersville Police Department) keep the arrest records in and around Carpentersville: the report and the booking record of each arrest stay with the agency that made it, separate from the court file and from the state repository.
The FBI's agency list also places three campus police departments and two other agencies in Kane County (the arrest records guide names each one); each keeps the records of its own arrests.
The Wayne Police Department, the Montgomery Police Department, the Huntley Police Department and three more are each listed by the FBI across several counties including Kane County, so their arrests are not broken out for Kane County here.
Together, the 19 agencies in Kane County with all twelve months of 2025 on file reported 9,151 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
