What Is Jefferson County Criminal Records
A criminal record in Jefferson County is an official compilation of documented interactions between an individual and the criminal justice system, maintained by law enforcement agencies, the circuit court, and state repositories. Under Illinois law, criminal records are created at multiple points in the criminal justice process, beginning with an arrest and continuing through charging, arraignment, plea or trial, sentencing, and any subsequent supervision or appeals.
The distinction between record types is significant for access purposes:
- Arrest records vs. conviction records: An arrest record documents that an individual was taken into custody; it does not indicate guilt. A conviction record reflects a formal finding or plea of guilty and a court-imposed sentence.
- Felony vs. misdemeanor records: Felony records involve more serious offenses and carry greater legal consequences. Misdemeanor records document lesser offenses. Both are maintained in the circuit court case files.
- Adult vs. juvenile records: Adult criminal records are subject to public access under Illinois law. Juvenile records are confidential under 705 ILCS 405/1-7 and are not available to the general public.
- Active warrants vs. historical records: Active warrants reflect outstanding court orders for arrest. Historical records document resolved cases, including dismissed charges and completed sentences.
The agencies that maintain criminal records in Jefferson County include:
- Jefferson County Sheriff's Office – arrest records, booking records, jail records
- Jefferson County Circuit Clerk – court case files, charging documents, dispositions, sentencing orders
- Illinois State Police Bureau of Identification – statewide criminal history repository
- Mount Vernon Police Department – local arrest and incident records
Records maintained by these agencies may include charges filed, arraignment dates, plea agreements, trial outcomes, sentencing details, fines, restitution orders, probation or parole conditions, and appeals.

How Long Does Jefferson County Keep Criminal Records
Legal Requirements
Illinois public records retention is governed by the Local Records Act, 50 ILCS 205, which establishes minimum retention periods for records maintained by local government bodies. The Illinois Local Records Commission sets schedules applicable to county courts and law enforcement agencies.
Retention by Record Type
| Record Type | Retention Period |
|---|---|
| Felony convictions | Permanent |
| Misdemeanor convictions | Permanent |
| Arrest records (no conviction) | Minimum 5 years; varies by agency |
| Dismissed or acquitted cases | Retained with disposition noted; permanent in court files |
| Juvenile records | Sealed at age 18 or 21 depending on offense; eligible for expungement thereafter |
| Pending cases | Retained until final resolution |
Agency Differences
- County Circuit Court: Court records are retained permanently under Illinois Supreme Court rules applicable to circuit courts.
- Sheriff's Office and Jail: Booking and arrest records are subject to local retention schedules, with a minimum retention period established by the Local Records Commission.
- Illinois State Police Repository: Conviction records are maintained permanently. The Individual in Custody Search reflects current IDOC custody status.
Physical vs. Electronic Records
Electronic records are retained for longer periods than paper records in many agencies. Paper records may be destroyed after scanning and verification, but the electronic version remains accessible.
Destruction vs. Sealing vs. Expungement
- Destruction refers to the physical or electronic elimination of a record after its retention period expires.
- Sealing restricts public access to a record while preserving it for law enforcement use.
- Expungement results in the physical destruction or return of arrest records and the removal of the record from public databases. Under Illinois law, expunged records are not accessible to the public and do not appear in background checks conducted for employment purposes.
Eligibility for expungement or sealing in Illinois is governed by 20 ILCS 2630/5.2, which sets forth qualifying offenses, waiting periods, and procedural requirements. Petitions for expungement or sealing are filed with the circuit court in the county of conviction.
Old Records Access
Records predating electronic case management systems may require special requests to the circuit clerk or may be located in the Illinois State Archives. Some older records exist only in paper format and require in-person review.
Federal Records
Criminal records maintained by the FBI under the National Crime Information Center (NCIC) are governed by federal law and are not subject to Illinois FOIA. These records are maintained separately from state and county repositories and follow distinct retention and access rules.
Practical Implications
Felony and misdemeanor convictions remain on an individual's record permanently unless expunged or sealed. Employment background checks conducted under the Fair Credit Reporting Act typically report convictions without a time limit, though many employers apply a seven-to-ten year review window as a practical matter. Professional licensing boards in Illinois may require full disclosure of criminal history regardless of the age of the conviction. Even if a county agency destroys physical records, electronic copies may exist in state databases unless the record has been legally expunged pursuant to 20 ILCS 2630/5.2.
