Mini-Cassia Jail Overview

The Minidoka County Mini-Cassia Criminal Justice Center page recognizes the adult jail as the custody facility for Minidoka County arrests. The Cassia County facility page gives the more detailed jail navigation and identifies the same Mini-Cassia Criminal Justice Center. The arrangement matters because a Minidoka arrest may lead to a court case in Rupert, while the adult booking and public custody entry appear on a Cassia-hosted regional jail page.

The facility holds adult men and women. Research from the 2020 DOJ PREA audit and the 2023 DHS/ICE PREA audit describes low, medium, and high custody levels, county inmates, state holds, federal custody, and ICE detainees awaiting transportation. The adult facility does not hold juveniles. Minidoka County juvenile custody is handled through the Mini-Cassia Juvenile Detention Center, where public roster access is restricted. For adult jail records, the practical question is not whether the roster is on a Minidoka web address. The useful question is whether the roster row names Minidoka County, a CR34 case, or MINIDOKA as the inmate type.

The Cassia facility page screenshot below comes from the official Mini-Cassia Criminal Justice Center page and shows the regional adult jail source used for inmate and family links.

This is the official facility page to pair with the roster, bookings, warrants, PREA, and jail phone channels when a Minidoka County adult is booked at Mini-Cassia.

Mini-Cassia Jail Capacity

The best sourced whole-facility number is the rated or design capacity. Both the 2020 DOJ PREA audit and the 2023 DHS/ICE PREA audit report a 170-bed adult facility. The research did not locate an official public dashboard with whole-jail average daily population, Minidoka-only jail population, annual adult bookings, or current daily population by county. A live roster can be counted on a given day, but that count changes and is not the same as a published annual population statistic.

The ICE audit gives a narrow, ICE-only slice of the jail population. It reported an average daily ICE population of 1 over the prior 12 months, 96 ICE detainees booked during that period, 2 ICE detainees present on the first audit day, and an average ICE custody length of 4 days. Those figures explain why the Mini-Cassia roster can show ICE or Border Patrol holds, but they should not be read as the whole adult jail population.

Mini-Cassia Inmate Lookup

The official adult lookup source is the Cassia County Jail Roster for the Mini-Cassia Criminal Justice Center. It is free to view in the captured text, and no login, payment, registration, or captcha was visible. The roster has a single visible search field, then a table of current detainees. For Minidoka County, scan the inmate type and the warrant, agency, and bond text. Rows may show MINIDOKA, Minidoka County, or CR34 case numbers tied to Minidoka court cases.

The adult roster is strongest for current custody. It is not a complete booking file and does not replace the court record, the public-record request process, or the state and federal locators. If a person has been sentenced to Idaho Department of Correction custody, the IDOC Resident/Client Search is the better system. If a roster row shows ICE or Border Patrol, the ICE detainee locator may become relevant after transfer. Federal sentenced prisoners are searched through the BOP inmate locator.

1. Open the official Mini-Cassia jail roster and search by last name first.
2. Review same-name entries by first name, BID, MNI, age, and booking date.
3. Check the inmate type column for MINIDOKA, CASSIA, STATE, ICE, or another hold category.
4. Read the warrant, agency, and bond column for CR34 cases or Minidoka County text.
5. Call the jail if current custody, bond, or release eligibility is unclear.

The roster table is useful because it combines booking date, days in jail, inmate type, case or agency text, and bond entries in one public view.

Mini-Cassia Jail Contact

Use the facility phone for live adult custody questions, visiting confirmation, release timing, and jail lobby instructions. Use Minidoka Sheriff's Records for Minidoka arrest files, booking sheets, booking photos, fingerprints, dispositions, and police report requests. Adult jail operations and Minidoka records are related, but they are not the same office. A person may be housed in Burley while the Minidoka sheriff, court, prosecutor, or records custodian handles the originating paperwork.

Mini-Cassia Jail Visitation

Adult visitation details were thin in the official accessible text reviewed. The Cassia facility page includes family and inmate information links, but the captured source material did not provide a complete adult in-person visiting schedule, video visiting schedule, visitor approval rule, dress code, or vendor name. Because those details affect entry at a jail lobby, the safest sourced instruction is to call the Mini-Cassia Criminal Justice Center before travel and ask for current adult visiting rules for the named detainee.

Do not use the juvenile visiting schedule for adult inmates. Juvenile visitation is a separate Minidoka County facility rule set. Adult visitors should expect identity screening and security restrictions, but the research did not locate an official adult page with exact ID type, arrival time, property limits, or appointment rules. A jail can change visit access because of classification, court order, discipline, medical status, transport, or staffing.

Note: Confirm the adult visit schedule with Mini-Cassia before driving from Rupert or another Minidoka County community.

Mini-Cassia Mail and Money

Official adult jail sources reviewed did not publish a complete mail format, commissary vendor, money-deposit vendor, phone-call vendor, tablet rule, or fee table. The adult facility address is published, but inmate mail often requires a specific name, booking ID, housing rule, sender information, paper limit, and banned-item policy. None of those adult mail details were located in the captured official text, so no vendor or fee should be inferred.

The Minidoka Sheriff's Records Division can help with public records, but it is not the commissary desk. Records staff can process requests for arrest files and booking sheets through the public-record channel. They should not be treated as the source for jail deposits unless the jail directs a caller there. The only reliable adult family-contact step from the current research is to call the jail with the inmate's full name and booking ID if available.

Mini-Cassia Booking Intake

The 2020 adult PREA audit gives concrete intake details. New adult arrests arrive through a secure sally port, are pat searched in a small intake area, and then move into the booking room for processing. That local intake path helps explain why a new Minidoka County arrest may not appear on the online roster at the instant of arrest. Staff must process the person, create or update the booking record, assign identifiers, and enter agency and hold information before the public table can show the entry.

Once booked, the roster may show a booking ID, MNI, sex, race, age, booked date and time, days in jail, inmate type, and warrant, agency, or bond text. The recent-bookings page is better for charge statute text, while the roster is better for current custody and bonds. Formal charge history moves through the Minidoka court and prosecutor path, so a roster entry and a court case should be read together when bond, charge status, or hearing information matters.

BID

The Mini-Cassia booking identifier shown on the public roster.

MNI

The master name index or person number used to help distinguish people.

Inmate Type

The roster category, such as MINIDOKA, CASSIA, STATE, or ICE.

Detainer

A hold from another agency that can affect release even when one bond is paid.

Mini-Cassia Housing and Programs

The adult jail is described as an indirect-supervision facility. The 2020 PREA audit lists blocks 100 through 1600, with dorm-style housing, double-occupancy cells, a small group of single-occupancy cells, work release, female housing, special management, medium custody, and maximum custody areas. Block 1400 is identified as the work-release block. The jail philosophy published by official pages says inmates are kept in the least restrictive manner allowed by classification and court instructions.

Official pages also mention adult continuing education, substance-abuse programs, and rehabilitative community-based programs. The accessible research did not locate a full class calendar, eligibility rule, medical request process, or grievance procedure. PREA reporting, however, is documented. The Cassia adult jail page gives zero-tolerance sexual abuse reporting contacts through jail staff, a jail lieutenant, a staff sergeant, and Cassia County Sheriff's Office pathways.

Mini-Cassia State and ICE Holds

Mini-Cassia can appear in state and federal custody paths without becoming a state prison or an ICE-only detention page. The jail roster may show STATE, Idaho DOC, ICE, or Border Patrol language because people can be held locally before transport or while another agency's hold is pending. Once a sentenced felony prisoner moves into Idaho Department of Correction custody, the statewide IDOC locator is the proper lookup channel. Once an immigration detainee transfers from Mini-Cassia, ICE's locator may be more useful than the county roster.

For federal sentenced prisoners, use BOP's locator. For federal pretrial defendants, a public county roster may show a local contract-jail hold while the person is physically at Mini-Cassia, but BOP usually does not function as a live pretrial jail roster. These distinctions prevent a common error: assuming every custody label on the Mini-Cassia roster is controlled by the same office. Jail staff can confirm local custody, but the court, IDOC, BOP, and ICE each control different records and decisions.
