Dekalb County Criminal Records
What Is DeKalb County Criminal Records
Criminal records in DeKalb County, Illinois, are official government documents that chronicle an individual's interactions with the criminal justice system, from initial law enforcement contact through final court disposition. These records are generated and maintained by multiple agencies operating at the local, county, and state levels.
Arrest records document the act of taking an individual into custody and reflect probable cause determinations made by law enforcement; they do not indicate guilt. Conviction records, by contrast, reflect a formal finding of guilt entered by a court of competent jurisdiction following a plea, bench trial, or jury verdict. Under Illinois law, these two categories carry distinct legal weight and different access rules.
Criminal offenses in Illinois are classified as either felonies — the more serious category, carrying potential imprisonment in a state correctional facility — or misdemeanors, which are less severe offenses typically resulting in fines or county jail sentences not exceeding one year. Juvenile records are generally sealed by operation of law pursuant to 705 ILCS § 405/1-8 and are not accessible to the general public in the same manner as adult records. Active warrants represent current judicial orders for an individual's arrest, whereas historical records reflect past proceedings that have reached final disposition.
The principal agencies maintaining criminal records in DeKalb County include:
- DeKalb County Sheriff's Office — maintains arrest records, booking data, and jail rosters
- DeKalb County Circuit Court — maintains case filings, arraignment records, pleas, trial transcripts, sentencing orders, and probation/parole documentation
- Illinois State Police, Bureau of Identification — maintains statewide criminal history records
- Local municipal police departments — maintain incident and arrest reports within their respective jurisdictions
The full spectrum of information captured in these records includes charges filed, arraignment proceedings, entered pleas, trial outcomes, sentencing details, and any subsequent probation or parole conditions.

Step 1 — Identify the appropriate agency. Court case records are held by the Circuit Court Clerk. Arrest and booking records are maintained by the Sheriff's Office or the arresting municipal police department. Statewide conviction histories are available through the Illinois State Police.

- Online, through the Illinois courts' electronic case access portal where available
- Through the Illinois State Police, for a certified statewide criminal history record check, which requires submission of a fingerprint-based request form and applicable fee

Step 5 — Await processing. In-person requests for court records are generally fulfilled on the same business day. Statewide background checks submitted through the Illinois State Police may require additional processing time.
