The Cassia County Inmate Population
The Cassia County inmate population is housed at the Mini-Cassia Criminal Justice Center in Burley. Cassia County identifies Kevin Horak as jail commander, while the law-enforcement page identifies Jarrod Thompson as sheriff. The county describes the facility as the place charged by state law with keeping adults who are charged with or convicted of public offenses. The public roster inspected on June 8, 2026, showed that the Cassia County jail population is broader than a single-county pretrial list. Rows used inmate-type values such as CASSIA, MINIDOKA, STATE, ICE, COURTESY HOLD, and US MARSHALL.
That mix matters when reading the Cassia County inmate population. A person may be in the building because of a Cassia County case, a Minidoka matter, a state hold, an immigration hold, a U.S. Marshals case, or a courtesy hold for another agency. Arrests and bond decisions can add people to the population. Releases, court orders, transfers to the Idaho Department of Correction, or pickup by another agency can remove them. Cassia County warns that the online database changes often and is not the final source for legal action.
Cassia County Inmate Population Statistics
Official local population statistics are limited. Cassia County publishes the live jail roster, recent bookings, and jail reports, but the county pages reviewed did not publish a current average daily population dashboard or annual booking count. The best sourced capacity figure in the research is the ICE PREA audit search result for Mini-Cassia, which identified a design capacity of 170. The same ICE source identified an average daily ICE population of 1 for the prior 12 months in the 2023 audit. Those figures should not be treated as a total jail average daily population.
| Measure | Figure | Source / Year |
|---|---|---|
| Mini-Cassia design capacity | 170 | ICE PREA audit search result, 2023 |
| Average daily ICE population | 1 | ICE PREA audit search result, prior 12 months in 2023 audit |
| State prisons in Cassia County | 0 | IDOC prison locations list |
| Sheriff's office staffing | 81 employees | Cassia County Sheriff's Office |
| County area | 2,580 square miles | Cassia County Sheriff's Office local context |
Cassia County Inmate Population Trends
The available trend record is not a full jail census. Cassia County did not publish multi-year average daily population figures in the reviewed county sources. The research does show a continuing federal and immigration oversight role through ICE inspection and PREA materials, plus the county's ongoing publication of PREA reports. The public roster remains the best current snapshot, but it is dynamic and should not be converted into an official average unless the county publishes that count.
| Year | Population Measure | Notes |
|---|---|---|
| 2023 | ICE ADP 1 | ICE PREA audit search result for Mini-Cassia, not total jail ADP |
| 2024 | Inspection source located | ICE ODO material exists, but total ADP was not available in accessible research |
| 2025 | 0 PREA allegations | Cassia 2025 PREA annual report, a conditions metric rather than population |
| 2026 | Mixed roster population | Roster inspected June 8, 2026, showed Cassia, Minidoka, state, ICE, and federal hold language |
Cassia County Inmate Population Makeup
The county roster gives row-level demographic and custody details, not an official aggregate breakdown. It shows sex, race, age, booked date, days in jail, inmate type, and warrant or agency bond information. Adult men and women appeared in the inspected roster and recent-bookings material. Juveniles are excluded by the county's jail disclaimer, so the Cassia County inmate population shown online should not be read as a complete youth custody source.
- Custody source: CASSIA, MINIDOKA, STATE, ICE, COURTESY HOLD, and US MARSHALL were observed as inmate-type values.
- Agency mix: Cassia, Minidoka, Twin Falls, Bingham, Border Patrol, and U.S. Marshals references appeared in agency or bond text.
- Demographics: sex, race, and age are displayed by row, but no official county-wide breakdown was located.
- Charges and holds: recent bookings showed misdemeanors, felonies, probation matters, extradition holds, and federal or immigration language.
Cassia County Jail Capacity
The Mini-Cassia facility is the only physical adult detention site resolved for Cassia County in the facility map. The 170-bed design capacity comes from ICE PREA audit source material, while the Cassia County jail page reviewed did not publish a bed count. No official Cassia County overcrowding dashboard, consent decree, jail construction plan, or population-release order was located in the research. Without a published total average daily population, the Cassia County jail cannot be described as over or under capacity from these sources alone.
Capacity note: The live roster is useful for current custody, but it is not the same as an official average daily population report.
Laws for Cassia County Jail Data
Idaho law explains why Cassia County jail records are partly public and partly limited. The public can examine and copy public records, but law-enforcement exemptions still protect certain investigatory records, privacy interests, and restricted information. The jail's duty to hold adults charged with or convicted of public offenses also comes from Idaho jail statutes, which connect booking, custody, and magistrate review.
Key Statutes:
Idaho Code 74-102 gives the public a right to examine and copy public records, subject to limits.
Idaho Code 74-103 governs agency response timing, including additional time when a request needs review.
Idaho Code 74-105 lists exemptions that can affect investigatory and law-enforcement records.
Idaho Code 20-601 covers county jail use and booking-process language.
Idaho Code 31-2202 makes keeping the jail and prisoners part of the sheriff's duties.
Cassia County State Prison Population
People sentenced to Idaho prison after a Cassia County case move into the Idaho Department of Correction Resident/Client Search rather than staying in a county roster search. IDOC says its locator covers people under IDOC jurisdiction, including prison, probation, and parole. The official IDOC prison list shows no state prison physically located in Cassia County, so the state prison path is a statewide lookup after sentencing or transfer.
The state locator differs from the Cassia County inmate population roster. IDOC may show status, IDOC number, facility or supervising district, felony offenses, sentencing county, case number, and sentence information. It does not replace the Mini-Cassia roster for a new arrest, bond, or current local booking photo.
Search Cassia County Inmate Population
The main search channel is the Cassia County jail roster. It is a free public DataTables roster with one global filter box rather than a separate first-name, last-name, and booking-number form. The row carries most public detail, so users should read across the table instead of expecting a separate profile page. The county says recent status changes may not appear and current custody can only be confirmed in person or by phone.

The roster image reflects why the filter box is only a first step. A full row can include the person's photo, BID, MNI, booked date, days in jail, inmate type, and agency or bond text.
- Open the Cassia County jail roster and use the "Filter records:" box.
- Start with the last name, then add a first name, MNI, BID, county code, or case fragment if needed.
- Read the row for booked date, days in jail, inmate type, warrant or agency text, and bond.
- Check the recent-bookings page if the person was newly booked but does not remain on the current roster.
- Call Mini-Cassia at (208) 878-1000 before taking legal, travel, bond, or visitation action.
Cassia County Roster Lookup Fields
The current-inmate lookup is simple, but it searches broad table text. That helps when a user has only a partial name or agency clue. It also means common names can return many rows. The table below follows the Cassia County roster controls captured in the research.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Filter records: | Text/global DataTables filter | No | Filters visible row text such as name, BID/MNI, booked date, inmate type, agency, and bond. |
| Show records per page | Dropdown | No | The source showed pageLength 25 as the default roster setting. |
| Column sorting | Clickable headers | No | Users can sort table columns in the browser when DataTables controls are active. |
| Pagination | Table navigation | No | Pagination is enabled, and no export option was observed. |
Past Cassia County Inmate Records
Released and older booking records require a wider search path. The recent-bookings report can help when the person was booked recently, even if the current roster no longer shows them. For records not online, Cassia County provides a public-records request form that cites Idaho Code 74-102 and asks for a clear description of the record sought. Useful details include full name, booking date, BID, MNI, case number, and the type of record requested.

The recent-bookings view is useful for intake history, while current custody still needs roster review or phone confirmation.
Cassia County Inmate Record Fields
A Cassia County inmate record is compact but dense. The roster uses local identifiers, demographic fields, custody-source labels, and bond or agency text in the same row. Recent bookings add charge descriptions and offense classification. These fields can point to the right court case, but they should not be treated as the final filed charge record.
| Field | What It Shows |
|---|---|
| Photo | Booking image, generic placeholder, or no usable image link. |
| Name | Bold name field, often with multiple lines. |
| BID and MNI | Mini-Cassia booking identifier and master name index number. |
| Booked Date/Time | Booking timestamp in the county roster format. |
| Days in Jail | Running count of days shown on the current roster. |
| Inmate Type | Cassia, Minidoka, state, ICE, courtesy hold, or U.S. Marshals type language. |
| Warrant/Agency Bond | Case, agency, warrant, hold, and bond amount information in one field. |
Cassia County Jail vs Prison
The Cassia County inmate population page should not be read as one universal inmate database. County jail, state prison, federal prison, and immigration detention are separate systems. The same person may move from Mini-Cassia to IDOC after sentencing, or may be picked up by a federal or immigration agency after a local hold clears.
| County Jail | State Prison | Federal or ICE | |
|---|---|---|---|
| Who Is Covered | Current Mini-Cassia inmates and recent bookings | People under IDOC jurisdiction | Federal sentenced custody or immigration detention |
| Where to Look | Cassia jail roster and bookings | IDOC Resident/Client Search | BOP locator or ICE ODLS |
| Common Clue | BID, MNI, bond, inmate type | IDOC number, sentence, supervising district | Register number, A-number, agency hold |
| Photo Source | Roster or bookings if published | State profile if available | No public federal mugshot gallery |
Cassia County State Federal Search
Use the IDOC Resident/Client Search when a Cassia County defendant has moved to state prison, probation, or parole. Use the BOP inmate locator for federal sentenced custody. Use the ICE Online Detainee Locator System for immigration custody, or ICE DRIL at 1-888-351-4024 when the online search does not resolve the question. Cassia County also links VINELink for victim notification and custody alerts.

IDOC is the right tool for sentenced Idaho custody, while the Cassia roster remains the first stop for a new county booking.
Cassia County Detention Facilities
The resolved facility map contains one Cassia County detention facility. Mini-Cassia is still more than a simple local jail because the public roster and ICE materials show regional, state, federal, and immigration roles tied to the same Burley facility.
- Mini-Cassia Criminal Justice Center - the adult county detention center for Cassia County, with Minidoka, state, ICE, courtesy-hold, and U.S. Marshals entries visible in the roster.
Cassia County Custody Terms
Several roster terms can change where to search next. The definitions below keep jail, court, state, and federal status separate.
- BID
- Mini-Cassia booking identifier tied to a jail intake.
- MNI
- Master name index number tied to a person record.
- Detainer
- A hold or notice from another agency, such as ICE, U.S. Marshals, or another county.
- PR bond
- Release on personal recognizance, meaning a promise to appear under court conditions.
- State hold
- Roster language that may point to IDOC or state-custody involvement.
