Boone County Inmate Search
How To Search for Inmate Records in Boone County in 2026
BooneILRecords.us provides data and publicly available information related to inmate records in Boone County, Illinois. Members of the public may access records that include booking information, custody status, charges, bond amounts, and court dates. This directory serves as a starting point for locating individuals currently held or recently processed through local detention facilities. Record availability may vary depending on the facility, the nature of the case, and applicable state law.
Inmate records may be searched through official county and state resources, including the Boone County Sheriff's Office, the Illinois Department of Corrections, public access terminals at the courthouse, and online search tools maintained by government agencies. The following methods outline the available channels for locating inmate information.
1. County Sheriff's Office Inmate Search
The Boone County Sheriff's Office maintains current custody information for individuals held at the Boone County Adult Detention Facility. Members of the public may access the inmate roster by visiting the Sheriff's Office official website and navigating to the Corrections & County Jail section. To conduct a search, users select a search type — by full legal name, booking number, or booking date — enter the applicable criteria, and review the results displayed. Selecting an individual record provides access to detailed information.
Information displayed in search results includes:
- Full legal name and aliases
- Booking photograph
- Current charges and charge descriptions
- Bond type and bond amount
- Facility location
- Booking date
- Expected release date (when available)
The inmate roster is updated on a regular basis; however, recent bookings may require several hours to appear in the online system. A mobile-optimized version of the site is accessible through standard web browsers on mobile devices.
2. State Department of Corrections Inmate Search
For individuals who have been convicted and transferred to a state correctional facility, the Illinois Department of Corrections individual in custody search provides a statewide database of individuals currently in state custody. This resource is distinct from the county jail roster, as it reflects post-conviction placements in Illinois state prisons rather than pre-trial or short-sentence county detention.
Users may search by last name, first name, or IDOC number. Results include the individual's current facility, projected release date, offense information, and sentence details. Individuals arrested in Boone County are held at the county jail pending trial or sentencing; transfer to a state facility occurs after sentencing on felony convictions, a process that may take several weeks following the court's judgment.
3. Federal Bureau of Prisons Inmate Locator
For individuals charged with federal offenses, the Federal Bureau of Prisons inmate locator provides a searchable database of individuals in federal custody. This resource applies when a person has been charged under federal law and is held in a federal detention facility rather than a county or state institution. The locator returns information including the individual's register number, age, race, sex, projected release date, and location of confinement.

Search Tips:
- Use the individual's full legal name as it appears on official identification
- Attempt name variations, including nicknames, maiden names, and alternate spellings

- Allow several hours for recent bookings to appear in the online system
- Individuals who have been transferred may not appear in the county roster
What If You Can't Find an Inmate:
If a search of the county roster returns no results, the individual may be held in a state prison (search the Illinois DOC database), in federal custody (search the BOP locator), in a facility in another jurisdiction, or may have been released. Name spelling variations and recent bookings not yet entered into the system are also common reasons a record may not appear. Members of the public may contact the jail directly at (815) 544-2144 for confirmation.
Are Inmate Records Public in Boone County?

Under current law, government agencies are required to make public records available for inspection and copying upon request, subject to specific statutory exemptions. Inmate booking records, custody status, and charge information are treated as public records accessible to any member of the public without a showing of need or purpose.

- Current inmate roster and population
- Booking information and booking date

Why Inmate Records Are Public:
The public availability of inmate records serves several recognized governmental interests. Transparency in the operation of detention facilities supports public confidence in the justice system. Public safety is advanced when community members can verify the custody status of individuals charged with offenses. Family members and legal representatives rely on booking information to locate detained individuals promptly. The bail bond industry depends on timely access to bond amounts and custody status to perform its licensed functions. Court proceedings also require accurate and accessible custody records.
Privacy Considerations:
Illinois law recognizes a balance between governmental transparency and individual privacy. While booking records and charge information are public, agencies are directed under 5 ILCS 140/7 to withhold information whose disclosure would constitute a clearly unwarranted invasion of personal privacy. Medical and mental health information, in particular, receives heightened protection. The public availability of booking photographs and arrest records may affect employment prospects and family relationships, a consideration that informs ongoing legislative discussions regarding expungement and record sealing under Illinois law.
What Is Inmate Records in Boone County?
Inmate records are official government documents created and maintained by correctional authorities to document the detention, custody, and release of individuals held in a correctional facility. These records serve as the authoritative account of an individual's passage through the detention system, from the moment of booking through release or transfer. The Boone County Sheriff's Office, which operates the Boone County Corrections & County Jail, is the official custodian of inmate records for individuals held at the county level.
Inmate records encompass several distinct categories. Booking records are created at the time of arrest and initial processing, capturing personal identification data, charges, and bond information. Custody records document the ongoing status of an individual's confinement, including housing assignments, classification level, and any transfers between facilities. Incarceration history reflects the complete record of an individual's prior bookings and periods of confinement within the county system. Release records document the circumstances and date of an individual's discharge from custody, whether by bond posting, sentence completion, transfer, or court order.
The distinction between county jail records and state or federal prison records is significant. The Boone County Adult Detention Facility holds individuals who are awaiting trial, serving short sentences for misdemeanor offenses, or awaiting transfer to a state facility following felony sentencing. State prison records, maintained by the Illinois Department of Corrections, pertain to individuals serving felony sentences in state institutions. Federal prison records, maintained by the Bureau of Prisons, apply to individuals convicted of federal offenses and confined in federal facilities.
