Minidoka County Inmate Population
Minidoka County uses the Mini-Cassia Criminal Justice Center for adult jail custody. The facility is in Burley, in Cassia County, but Minidoka County's own jail page names it as the adult detention path for the county. That makes local lookup work different from a single-county jail page. A person arrested in Rupert or elsewhere in Minidoka County may be booked at a Burley address, while the criminal case may still be filed through Minidoka County court channels in Rupert.
The adult jail population includes people held before trial, people serving short local sentences, people held for the state, and some federal or immigration holds. The public roster uses inmate type values such as MINIDOKA, CASSIA, STATE, and ICE. Minidoka cases also show up through CR34 case numbers or "MINIDOKA COUNTY" text in the bond and agency column. Juveniles are not part of the adult roster. The Mini-Cassia Juvenile Detention Center in Rupert has its own restricted custody rules.
Minidoka County Jail Statistics
The strongest official population figures come from PREA audit records and facility pages, not from a county-wide live dashboard. The adult jail has a documented design capacity, while full adult average daily population, Minidoka-only population, and full annual adult booking totals were not published in the official static sources reviewed. For current adult custody, the live roster is the practical source, but that count changes by the day.
| Measure | Figure | Source / Year |
|---|---|---|
| Mini-Cassia Criminal Justice Center capacity | 170 beds | 2020 DOJ PREA audit and 2023 DHS/ICE PREA audit |
| Adult jail full average daily population | Not published in official static source reviewed | Live roster varies daily |
| ICE average daily population | 1 detainee | 2023 DHS/ICE PREA audit |
| ICE detainees booked in prior 12 months | 96 | 2023 DHS/ICE PREA audit |
| Juvenile detention average daily population | 6 residents | 2023 juvenile PREA post-audit section |
| Juvenile day-one onsite population | 7 residents | 2023 juvenile PREA audit |
Minidoka County Population Trends
Minidoka County did not publish a full multi-year adult jail trend table in the official sources reviewed. The available trend picture is narrower. The adult facility's rated capacity stayed at 170 beds across the 2020 DOJ PREA audit and the 2023 DHS/ICE PREA audit. ICE use was small in daily count but real in booking flow, with an average daily ICE population of 1 and 96 ICE detainee bookings in the 12 months reported in the 2023 audit.
| Year / Source | Population or Capacity | Notes |
|---|---|---|
| 2020 DOJ PREA audit | 170-bed adult capacity | Indirect-supervision adult jail with multiple housing blocks. |
| 2023 DHS/ICE PREA audit | 170 design capacity; ICE ADP 1 | ICE-only subpopulation, not the whole adult jail count. |
| 2023 juvenile PREA audit | 16 capacity; ADP 6 | Juvenile facility only, separate from adult public roster. |
| Current roster | Daily changing adult count | Official roster can be counted on the day searched. |
These gaps matter. A current roster count is useful for a family search, but it is not the same as an audited annual average. A Minidoka-only jail population is also hard to separate from the full Mini-Cassia population because the adult jail serves both Minidoka and Cassia custody traffic.
Who Minidoka County Holds
The adult Mini-Cassia population includes men and women at low, medium, and high custody levels. The PREA materials describe female units, special management, medium custody, maximum custody, dorm-style housing, double-cell housing, single-cell housing, and a work-release block. The roster adds a public view of the holding agency through its inmate type column. That column is one of the most useful fields for Minidoka County users because the roster sits on a Cassia County website.
- Pretrial adults are people waiting for a first appearance, bond action, plea, trial, or other court step.
- Local sentenced adults may serve short jail terms at Mini-Cassia under court orders.
- State holds can involve IDOC custody or people waiting for state prison transport.
- ICE and federal holds can appear on the jail roster, but federal locators are separate tools.
- Juveniles are handled through the juvenile facility and court process, not the public adult roster.
Minidoka County Jail Capacity
The adult jail's 170-bed capacity is supported by both the 2020 adult PREA audit and the 2023 ICE PREA audit. The 2020 audit describes a single building with indirect supervision, central control, housing blocks 100 through 1600, dorm areas, double-occupancy cells, and five single-occupancy cells in block 900. It also identifies block 1400 as work release. No official source reviewed published a current overcrowding dashboard or a full adult average daily population trend.
The juvenile facility reports a much smaller design capacity. Its 2023 PREA audit reports 16 designed beds, one housing unit, and no over-capacity condition during the prior 12 months. The juvenile figures should not be blended into the adult jail count because those residents are not searched through the public adult roster.
Minidoka County Custody Laws
Idaho law explains why some jail and arrest information is public while other details are withheld. The Minidoka Sheriff page points to the sheriff's duty to take charge of the county jail and prisoners, but adult custody is handled through the regional Mini-Cassia jail. Public access also depends on Idaho's public records laws, court rules, and exemptions for active law-enforcement records, juvenile records, safety, privacy, and sealed cases.
Key Statutes:
Idaho Code § 31-2202 gives the sheriff duties tied to arrests, magistrate appearances, courts, and jail custody.
Idaho Code § 74-102 gives people the right to examine and copy public records unless another law limits access.
Idaho Code § 74-124 protects some investigatory records but keeps basic arrest facts outside that definition.
Idaho Code § 20-602 addresses jail room and separation requirements, including separation of males and females.
Search Minidoka County Inmates
The official current adult roster is the Cassia County Jail Roster for the Mini-Cassia Criminal Justice Center. The roster is free to view and no login, payment, or captcha was visible in the research capture. It uses a simple search box and a table. For Minidoka County, the key is to search beyond the name. Look at inmate type, agency text, bond lines, and CR34 case numbers.
The screenshot below comes from the official roster source. It shows why Minidoka County users must read the table fields closely, because a Cassia-hosted page can still include Minidoka cases and agency labels.
The roster is strongest for current custody, booking date, days in jail, inmate type, case or agency text, and bond lines. It is not a full court record, full booking file, or state prison locator.
- Open the official Mini-Cassia roster and search by last name first.
- If the name is common, add a first name or scan same-name rows.
- Check inmate type for MINIDOKA, STATE, ICE, or another agency label.
- Read the warrant, agency, and bond column for CR34 case numbers or Minidoka County text.
- If the person is not listed, call the jail or use records, court, IDOC, BOP, ICE, or VINELink channels.
Minidoka County Roster Fields
The Mini-Cassia roster is a table rather than a profile-card system in the accessible research text. Its fields are detailed enough to answer many current-custody questions, but they do not show full dates of birth, home addresses, housing units, medical information, court dates, or fingerprints. Recent bookings may show fuller charge text, while court records show formal filed charges and outcomes.
| Field | What It Shows |
|---|---|
| PHOTO | Booking photo column exists, though not every visible text capture confirms an image for each row. |
| NAME | Last name and first or middle names, sometimes wrapped across lines. |
| BID and MNI | Booking ID and master name index/person number used by the jail system. |
| BOOKED DATE/TIME | Booking date and time in the roster table. |
| DAYS IN JAIL | Running count of days in custody. |
| INMATE TYPE | Agency or category, including CASSIA, MINIDOKA, STATE, and ICE. |
| WARRANT/AGENCY BOND | Case numbers, holds, agencies, county labels, and bond amounts. |
Minidoka County Booking Records
The recent-bookings feed is useful when the arrest is new or when charge wording matters. It has a photo column and charge text with statute codes, felony or misdemeanor labels, and entries such as controlled-substance possession, aggravated assault, domestic battery, DUI, probation violation, parole violation, and Border Patrol holds. It is not the same as a release list or full archive.
For records that are not on the roster, the Minidoka Sheriff's Records Division is the local fallback. The records page says individual arrest files contain pictures, fingerprints, dispositions, and booking sheets. It directs users to complete the county record request form and allow three business days for response. The form can be routed by fax, email, mail, USPS, or hand delivery to the proper custodian.
| Channel | Best Use | Limit |
|---|---|---|
| Current roster | Current adult custody and bond or hold lines | Does not show all booking-file details. |
| Recent bookings | Fresh charge text and booking entries | Not a full custody-history archive. |
| Records request | Booking sheets, arrest files, photos, fingerprints, dispositions | Can be redacted or denied under Idaho law. |
| iCourt Portal | Charges filed after arrest and court events | Court access follows judicial records rules. |
Jail Roster vs IDOC Search
A Minidoka County inmate population search can fail if the person has moved from jail to state custody. The Mini-Cassia roster is for people currently held at the regional jail. The Idaho Department of Correction Resident/Client Search covers people on court probation or under IDOC jurisdiction, including prison, probation, and parole. IDOC updates its locator daily, but it warns that location and status can change quickly.
| Question | Mini-Cassia Roster | IDOC Locator |
|---|---|---|
| Who it covers | Current adult jail detainees and holds | State prison residents, probationers, and parolees |
| Best search clue | Name, BID, MNI, CR34 case, inmate type | Last name or IDOC number |
| Common status | Pretrial, local sentence, state hold, ICE hold | Sentenced felony custody or supervision |
| Main limit | Not a prison locator or full court case file | Not a county booking roster |
Federal and ICE Lookup
Some Mini-Cassia roster rows can show ICE, Border Patrol, federal, or other agency holds. Those entries do not make the county roster a federal custody database. Use the Federal Bureau of Prisons inmate locator for people sentenced to federal prison. Use the ICE detainee locator for people in immigration custody. For custody or release notices, use Idaho VINELink as a notification service rather than a substitute for the court record.
The 2023 ICE PREA audit confirms that Mini-Cassia can hold ICE detainees awaiting transportation, but the ICE average daily population was only 1 in that audit period. That keeps the ICE discussion in proportion. Most Minidoka County jail searches should start with the regional roster, then move to ICE only when the roster or agency facts point that way.

Minidoka County Detention Facilities
Minidoka County has two detention facilities in the research map. They serve different populations and must not be searched the same way. The adult jail has a public roster through Cassia County. The juvenile detention center does not publish a public resident roster.
- Mini-Cassia Criminal Justice Center - regional adult jail in Burley serving Minidoka and Cassia, with county, state, ICE, federal, and other agency adult holds.
- Mini-Cassia Juvenile Detention Center - juvenile detention facility in Rupert for male and female juveniles ages 11 to 17, with restricted records and no public roster.
