Twin Falls County Inmate Population Snapshot
The official local source found for the Twin Falls County inmate population is the Twin Falls County Sheriff's Office, which publishes a dated daily headcount PDF from its public site. That matters because the county does not present the jail count as a searchable public database with name fields, filters, and profile tabs in the sources reviewed for this build. The daily report is a point-in-time jail list for people held by the Twin Falls County Adult Detention Facility, also called the James R. Munn Detention Facility in the Idaho Sheriffs' Association jail directory.
The jail population includes people recently arrested by local agencies, people held on warrants, pretrial detainees awaiting court action, people serving local jail sentences, and people waiting on transfer to another jurisdiction. A person sentenced to Idaho prison custody is no longer best tracked through the county jail count; that search moves to the Idaho Department of Correction Resident/Client Search. Federal and immigration custody use still different tools, so a missing name on the daily county headcount does not prove the person is free.
Twin Falls County Inmate Population Statistics
The strongest local figures in the research are capacity and a dated headcount. County medical-services procurement material from 2023 described the jail as having capacity for approximately 254 inmates. The sheriff's official daily headcount PDF for June 8, 2026 listed more than 300 people. Those are not the same type of number. One is a rated-capacity figure from county materials, while the other is a daily operational snapshot from a specific report date.
| Measure | Figure | Source / Date |
|---|---|---|
| Daily jail headcount | More than 300 people listed | Sheriff Headcount-6-08.pdf, June 8, 2026 |
| Rated / bed capacity | Approximately 254 inmates | Twin Falls County jail medical-services RFI material, 2023 |
| Local detention facilities | One county jail located | Facility map and official jail directory research |
| Annual bookings or ADP | Not located in official sources | Sheriff, county records, and jail directory review |
Because no official annual booking total, average daily population, length-of-stay figure, or demographic breakdown was located, the Twin Falls County inmate population should not be described with estimated rates or inferred groups. The daily headcount is useful for current custody. It is not a demographic report.
Twin Falls County Inmate Population Trends
Trend language needs care because the research found two defensible local data points, not a full multi-year jail report. The 2023 capacity figure gives a baseline for the building. The June 8, 2026 daily headcount shows that a dated public report can list a number above that earlier capacity figure. That supports a cautious reading: daily counts can exceed the capacity number found in older county materials, and each figure should be tied to its source.
| Year / Date | Count or Figure | What It Means |
|---|---|---|
| 2023 | Approximately 254 capacity | Capacity context from county medical-services procurement material. |
| June 8, 2026 | More than 300 daily headcount rows | Official sheriff daily custody snapshot, not an annual average. |
| 2024-2025 | Not located | No official ADP or annual booking table was found in reviewed sources. |
A later expansion could add Bureau of Justice Statistics, Vera Institute, or Jail Data Initiative trend data if it is located and matched to Twin Falls County. Until then, the local site should not guess at incarceration rates, annual admissions, or demographic shifts.
Twin Falls County Jail Capacity
The Twin Falls County Adult Detention Facility is the county-level jail for adult custody. The capacity figure located in county procurement material was approximately 254 inmates, while the dated June 8, 2026 headcount listed more than 300 people. That contrast is useful, but it should not be stretched into an unsupported legal conclusion about overcrowding, litigation, or a construction plan. The reviewed official sources did not locate a consent decree, DOJ investigation, county-issued litigation summary, or current jail-expansion page.
The better practical point is simple: the Twin Falls County inmate population can be higher than a historic rated-capacity figure on a specific report date, and the public must check the current sheriff headcount for the current day. Any person planning a visit, bond payment, records request, or inmate-service step should call the jail at 208-734-9090 because daily custody conditions can change after release, transfer, court order, lockdown, or a new booking wave.
Laws for Twin Falls County Jail Records
Idaho law gives the public a path to examine many public records, but jail and law-enforcement records are not all open in the same way. The Twin Falls County daily headcount is a public custody artifact. More detailed booking files, investigatory records, juvenile records, medical or classification records, sealed records, and protected personal data may be withheld or redacted under Idaho law.
Key statutes and rules:
Idaho Code 74-102 establishes the public right to examine and copy public records unless an exemption applies.
Idaho Code 74-103 sets response timing for public-record requests, commonly three working days unless extended.
Idaho Code 74-124 governs law-enforcement-record exemptions and basic arrest-information disclosure.
Idaho Code 20-605 addresses county jailer custody duties, while Idaho Code 20-622 supports jail inspection and standards oversight.
Search Twin Falls County Inmate Population
A current Twin Falls County inmate search starts with the sheriff's public site and the newest headcount PDF. The research located a dated PDF, such as the June 8, 2026 report, rather than a public portal with a last-name form. That changes the workflow. Readers should open the sheriff homepage, choose the current headcount link, then use the browser or PDF viewer search box to search by last name or other visible text.
- Open the Twin Falls County Sheriff's Office homepage.
- Open the current Headcount or dated headcount PDF.
- Use the PDF viewer's find command to search for the person's last name.
- Read the row as a current custody snapshot, not as a full case file.
- Call 208-734-9090 if the person is missing or the row does not answer the custody question.
| Field | Type | Required | Notes |
|---|---|---|---|
| PDF text search | Browser or PDF viewer search | No | Search visible report text, usually by last name. |
| Report date | PDF filename or heading | N/A | Use the newest report from the sheriff site. |
| Roster rows | Public report table | N/A | Rows are visible without login, but no official sort or filter controls were located. |
Twin Falls County Inmate Record Fields
The headcount confirms whether a name appears in the sheriff's current daily custody list. It should not be treated like a full booking jacket. The inspected PDF did not show public mugshot images, and the research did not confirm profile tabs for housing, bond, court dates, or charge details. If those facts are needed, the safer chain is jail phone, public-records request, and iCourt.
| Field | What It Shows |
|---|---|
| Report date | The date of the sheriff's daily custody snapshot. |
| Inmate name | Name text visible in the roster row. |
| Custody inclusion | Presence on the report indicates inclusion in that day's headcount. |
| Mugshot | No public booking-photo image was visible in the inspected PDF. |
| Charges or bond | Use only what the row displays; confirm missing details with jail or court records. |
| Court case | Use Idaho iCourt for case number, filed charges, hearing dates, and disposition. |
Where Twin Falls County Detainees Are Held
Official facility research found one local county jail facility and no separate city jail, regional jail, state prison, BOP prison, or ICE detention center physically in Twin Falls County. Arrests from Twin Falls, Buhl, Filer, Kimberly, Hansen, Hollister, Murtaugh, and nearby local agencies may still route to the county jail. The local jail is the first stop for current local custody, but it is not the only possible custody system.
- Twin Falls County Adult Detention Facility holds adult pretrial detainees, warrant arrests, local sentences, and people awaiting transfer.
| Custody Type | Where to Search | Best Use |
|---|---|---|
| County jail | Sheriff daily headcount PDF | Current local custody and recent bookings. |
| State prison or supervision | IDOC Resident/Client Search | Sentenced prison custody, probation, or parole when public. |
| Federal prison | BOP Inmate Locator | Federal sentenced custody and certain released federal records. |
| Immigration detention | ICE Online Detainee Locator | ICE custody by A-Number or biographical fields. |
Twin Falls County Records Requests
When the headcount does not show enough detail, the county public-records route is the next formal channel. The Twin Falls County public records request page says requests may be made online, the first 100 pages are free, and the county generally has three working days to respond unless more time is needed, in which case the response period can extend to 10 working days. Fees may apply for locating or copying records depending on the request scope.
A request for jail records should be narrow and factual. Include the person's full name, date of arrest or custody date if known, the type of record requested, and whether the request is for a booking record, custody confirmation, or a booking photograph. Idaho Code 74-124 can limit law-enforcement records, so a request may result in redactions or a denial for protected details.
Jail Records and Court Charges
Jail custody and court charges are linked, but they are separate records. The jail headcount tells whether the person appears in county custody. The court record begins when the prosecutor files a complaint, information, citation, or indictment. Idaho's Odyssey/iCourt portal is the public court-search route for case numbers, filed charges, hearings, and dispositions that follow a Twin Falls County arrest.
Arrest terms can change once the prosecuting attorney reviews the case. A booking basis may be reduced, amended, dismissed, or replaced by a different filed charge. Idaho Court Administrative Rule 32 controls public court-record access and excludes confidential court data. For the court side of the same event, use the Twin Falls County court records after jail arrest page.
Twin Falls County Custody Alerts
Idaho participates in VINELink, a victim-notification and custody-status service. VINELink is useful when a person wants alerts rather than a one-time roster check. Registration may be needed for notifications, and the user should still confirm urgent custody questions with the jail because a notification system and a daily PDF do not update in the same way.
No official Twin Falls County Sheriff's Office mobile app was confirmed in the official research. Do not substitute third-party police scanner, mugshot, or records-search apps for an official sheriff tool.
Note: If a name is missing from the headcount, check recent release, IDOC transfer, federal custody, ICE custody, and direct jail phone confirmation.
Twin Falls County Locator Screens
The statewide IDOC Resident/Client Search is the correct route once a Twin Falls County case results in state prison custody or supervision.
The IDOC locator uses state correctional identifiers and status fields, so it should not be confused with the county jail's daily headcount PDF.
Twin Falls County Jail Terms
Several custody terms appear across jail, court, and state-prison records. A short definition helps keep the Twin Falls County inmate population search from mixing systems.
- Booking
- The jail intake process after arrest, including identity checks and custody processing.
- Detainer
- A hold or request from another agency that may block release from local custody.
- Remand
- A court order returning or holding a person in custody.
- Classification
- The jail's risk and housing assessment used to assign custody level and placement.
- DOC
- The Idaho Department of Correction, which handles state prison and supervision records.
