Federal Release Systems Differ
Federal and immigration custody is a system category, not one Sevier County facility. BOP mainly answers where a sentenced federal prisoner is held and whether BOP reports a past or future release date. USMS manages many people detained before trial, awaiting designation, or moving between contract facilities. ICE handles civil immigration detention and publishes a separate locator for qualifying cases.
A person may appear briefly in SCSO custody because of a federal arrest, hold, or contract movement, then disappear from the county roster before any useful BOP entry exists. The SCSO transfer transaction identifies the county event. A federal court order, USMS contact, BOP locator, or ICE record identifies the next stage.
| System | Best use |
|---|---|
| BOP | Sentenced federal inmate location and BOP release date |
| USMS | Federal pretrial custody and transport |
| ICE | Qualifying current or recent immigration custody |
| SCSO | Sevier County handoff or local release transaction |
Search BOP Release Records
Use the BOP Inmate Locator for federal inmates from 1982 to the present. Search by BOP register, DCDC, FBI, or INS number when known. The name route accepts first, middle, and last name with age, race, and sex refinements. Match more than a name before relying on a result.
- Choose identifier or name search and enter the known data.
- Review the candidate's name, register number, age, race, and sex.
- Read the release date and location exactly as BOP displays them.
- Check whether the date is past, future, unknown, or accompanied by a facility.
- Request BOP records if the public entry does not answer the custody question.
The matching successful capture shows the official federal search interface.

The locator is nationwide and not filtered by Sevier County. Search identity and federal number, not county of conviction alone.
Read BOP Release Results
BOP says a past release date with no facility indicates the person was released on that date and is no longer in BOP custody. A location of “RELEASED” has the same BOP-limited meaning. It does not rule out federal supervised release, state or county custody, an unresolved warrant, or immigration detention.
“IN TRANSIT” is not release. An “UNKNOWN” date means the term is undetermined. A future date is projected and can be recalculated. BOP warns that First Step Act changes and other computations can affect public dates. Use the precise phrase “no longer in BOP custody” unless another official record establishes a broader community status.
- Projected date
- A future estimate that can change before physical release.
- Released
- BOP custody ended, without resolving every other system.
- In transit
- Federal custody and movement continue.
- Supervised release
- Court-ordered federal supervision after confinement.
USMS Sevier Custody Checks
USMS does not offer a public historical release locator comparable to BOP. A federal defendant who is detained before trial or awaiting designation may have no useful BOP result. Use the federal court detention or release order, counsel, authorized docket access, or the responsible USMS district contact. The court order explains legal authority, while USMS or the holding facility documents physical custody and transport.
A marshal transport is continued custody. If SCSO says the person was released to USMS, preserve the county transfer time and seek the next federal record. Do not state that the person entered BOP until BOP or another official source confirms commitment to that system.
The BOP Notice of Release and Arrival form illustrates the federal custody chain. It can record the release date and method, institution, release to community or detainer, transportation, expected arrival, supervision jurisdiction, and proposed residence. Access to detailed personal records may require consent or FOIA processing and can be limited by privacy or law-enforcement exemptions.
Note: A federal court order can authorize release without proving the exact moment the holding facility carried it out.
ICE Recent Release Window
Use the ICE Online Detainee Locator for qualifying immigration custody. The preferred search uses the A-number and country of birth. Exact-name biographical search is the alternative. ICE states that the locator can include people currently in detention and people released from ICE custody within the last 60 days. Minors are excluded.
This is a meaningful recent-release window, but it belongs only to ICE. It is not a Sevier County jail release feed and not a permanent immigration history. A negative result can reflect exact-match issues, age limits, a release older than the window, or lack of qualifying custody. Preserve the search date because the visible window moves.

ICE Detainers After SCSO
Immigration detainers are central to this custody route. ICE describes a detainer as a request that a local agency give notice before release and maintain custody for up to 48 additional hours beyond the time local release would otherwise occur so ICE can assume custody. No Sevier-specific ICE agreement was verified. The actual SCSO record must establish whether a transfer took place.
When SCSO records a handoff, report two events: Sevier County custody ended, and ICE custody began if the federal source confirms it. Do not report a community release. If ICE later reports release from its custody, that is a second event with its own date and limits.
An SCSO roster disappearance combined with a known detainer is still not enough by itself. Request the county transfer recipient and search ICE with accurate identifiers. If the two sources conflict, ask each agency to explain its own record.
No Federal Prison in Sevier
The local geography also requires care. No BOP prison was identified within Sevier County. A federal relationship can still begin in the local Jail, Annex, a contract facility elsewhere, federal court, or an ICE process. Facility location and legal custodian are separate facts.
The SCSO Jail and Annex form a two-site county system. A federal handoff can occur from either local custody path, and a person can move under USMS authority without becoming a sentenced BOP inmate. Search the agency responsible for the stage, not the nearest facility name.
No single public street address, release entrance, or hours apply to this federal and immigration category. Verify the current institution, detention center, court, or office before travel. A locator location can change during transport.
Federal Records Request Paths
BOP's FOIA process is the route for detailed modern federal prison records beyond public locator data. Request the specific record needed, such as release information, custody history, or a release notice, while recognizing that consent, privacy, and law-enforcement limits can restrict disclosure. For pre-1982 federal records, BOP directs researchers to the National Archives with the name, date of birth or approximate age, race, and approximate incarceration dates.
ICE and USMS records follow their own federal procedures. Do not send a BOP request for an ICE-only detention or assume USMS maintains the sentenced-prison record. Start with the event and agency named in the court or SCSO file.
| Record needed | Route |
|---|---|
| Modern sentenced-prison detail | BOP locator, then BOP FOIA |
| Pre-1982 federal prison history | National Archives route described by BOP |
| Pretrial detention or transport | Federal court, counsel, or USMS |
| Immigration custody | ICE locator, hotline, and ICE records process |
Verify Federal Release Evidence
Use the strongest identifier available: BOP register number, FBI number, INS number, A-number, federal case number, SCSO booking number, or date of birth with full legal name. Record the query date, time, agency, exact label, and stable search page. Dynamic results and displayed custody can change.
A reliable chronology may combine the SCSO transfer transaction, federal court order, USMS status, BOP result, ICE locator observation, and later supervision record. Each source should retain its own language. “Released from SCSO to ICE” and “released from ICE custody” are different claims. “Not in BOP custody” does not settle either one.
The broader Sevier County release-record search can help identify the county side of a federal transfer. Keep the federal result separate from county release evidence.
A former BOP result may also coexist with federal supervised release. The sentencing court and probation office, not the BOP facility field, explain that later legal status. If a new county or state arrest occurs, report the new custody separately rather than treating the old federal release date as current freedom from all systems.
Note: Confirm all live portal labels, office contacts, and operating hours because federal systems and routes can change.
