Federal BOP Release Record Scope
The BOP Inmate Locator covers people held in or released from the federal prison system within its published data scope. It is nationwide. No BOP prison was identified in Cassia County, so the locator is a system page rather than a local facility roster. A Cassia-area person can still appear after a federal conviction and commitment to a BOP institution elsewhere.
BOP is relevant after federal sentencing. Before that point, a person may be held for the U.S. Marshals Service at Mini-Cassia or another contract jail without a useful BOP result. Immigration detention belongs to ICE. Idaho felony imprisonment belongs to IDOC. County charges and releases belong to the responsible county jail and court.
“Not in BOP custody” is custodian-specific. It does not promise that the person is physically free or has no other case or hold.
The BOP public result can support identity, register number, age, race, sex, release date, and custody wording. It does not provide the Cassia jail’s checkout time, an ICE destination, a county court disposition, or a public mugshot field.
Search Federal BOP Release Records
Search by number when possible. A BOP register number is more stable than a name and avoids confusion among similar results. The locator also supports FBI, INS, and DCDC numbers within its number-search options. The name search uses first, middle, and last name, with race, age, and sex filters available to narrow matches.
- Confirm that the person was federally sentenced and likely entered BOP custody.
- Open the locator and choose number search when a register or other accepted number is known.
- Otherwise use the full legal name and narrow the results with available identity fields.
- Compare the register number, age, race, sex, and release information before selecting the record.
- Read the release date with the displayed custody status and the date the search was checked.
- Use the federal docket or responsible agency to confirm a transfer or release destination.
A name-only result is not enough. Names, aliases, and spelling variants can produce more than one candidate. Federal court documents may supply the register number or judgment needed to resolve identity. Do not import a Cassia booking ID into the BOP number field because local and federal identifiers serve different systems.
Federal BOP Release Result Fields
BOP results are compact. Their value comes from reading all fields together and keeping the search date. A past release date can document the date associated with departure from Bureau custody, but later custody elsewhere is outside that statement.
| Field | How to use it |
|---|---|
| Name | Compare the complete displayed identity with the federal case. |
| Register number | Use as the stable BOP identifier. |
| Age, race, and sex | Narrow similar names without treating one field as conclusive. |
| Release date | Record the date exactly as displayed and tie it to BOP custody. |
| Location or custody phrase | Shows current BOP status, including “Not in BOP custody” where applicable. |
The official BOP search interface provides separate find-by-number and find-by-name routes.
The two routes reinforce why a federal number is preferable. Whichever route is used, compare the result against the federal case before relying on the date.
What BOP Release Wording Means
A release date is tied to the Bureau’s record. “Not in BOP custody” means BOP does not report current custody. It can be consistent with community release, transfer to another authority, removal proceedings, or another status outside BOP’s control. The phrase should not be shortened to “free.”
A projected future BOP date and an actual past release date also differ. Keep the display context. Federal sentence calculations, court changes, and agency events can affect a future date. The public locator should not be used as a home-built sentence calculator.
- BOP custody
- Confinement or status under the Federal Bureau of Prisons.
- Register number
- The person’s stable BOP identification number.
- Federal pretrial detention
- Custody before federal sentencing, commonly managed through USMS rather than BOP.
- Release date
- The date shown in the BOP record, limited to the Bureau’s custodial context.
A federal court judgment explains the sentence. The docket can document later orders. BOP confirms Bureau status. A receiving agency confirms any handoff. Those sources answer distinct questions.
Cassia Federal Custody Transitions
Mini-Cassia has held federal populations. A person may first appear on its local adult roster under a federal or courtesy hold. Leaving that roster can mean movement with the U.S. Marshals Service. BOP becomes the right locator only after sentencing and entry into the Bureau’s system.
| Stage | Primary confirmation route |
|---|---|
| Held at Mini-Cassia | Jail confirmation, holding-agency field, and federal case |
| Federal pretrial movement | USMS District of Idaho and federal docket |
| Sentenced federal imprisonment | BOP Inmate Locator and Bureau records |
| Departure from BOP | BOP result plus any receiving custodian or supervision record |
| Immigration custody | ICE Online Detainee Locator and ERO, not BOP |
The building address does not decide legal custody. Mini-Cassia can house a person while the federal authority controls the case. Likewise, a BOP result does not describe an earlier county release sheet. Preserve the local booking ID and the federal register number as separate identifiers.
Verify Federal BOP Releases
Begin with the BOP result, then check the federal docket for the judgment and later orders. If the record says “Not in BOP custody,” identify whether another authority had a detainer or received the person. The Mini-Cassia federal holds record covers the local USMS and ICE handoff distinction.
For older or more detailed Bureau records, use the BOP’s custodian-specific FOIA process. Protected personal details may require identity proof, consent, or authorization. Ask for a narrow record tied to the register number and date range. Federal FOIA rules and exemptions differ from Cassia County’s Idaho public-record process.
The U.S. Marshals Service maintains its own prisoner-tracking records. ICE has separate immigration files. A court owns judicial records. Sending one broad request to BOP for all of them will not produce a complete custody chain. Route each part to the agency that created it.
Federal Versus Cassia Release Records
An ordinary Cassia jail release can result from bond, own recognizance, dismissal, time served, or completion of a county sentence. That event is confirmed by Mini-Cassia and the owning court. It will not appear as a BOP release unless a separate federal sentence placed the person in Bureau custody.
An Idaho state-prison release uses IDOC status, sentence, parole, and supervision records. IDOC’s Released to Supervision field is not a BOP release date. VINE may provide a participating-agency alert, but it is not a certified federal release record. ICE ODLS has a limited recent-release window and serves immigration custody.
The Cassia County released inmate search explains the full adult custodian chain. For the federal branch, keep the sequence clear: local hold, USMS movement, federal sentencing, BOP custody, then BOP departure or transfer. Skipping a step can turn a database change into an unsupported claim about physical freedom.
Federal BOP Record Contact Route
No local Cassia address or phone can serve as the contact card for the nationwide BOP system. Use the institution shown in the matched BOP record for facility-specific questions and the Bureau’s official locator and record channels for nationwide status. The responsible federal court handles its docket.
Nationwide sentenced-federal system
BOP Inmate Locator
Use the matched register number and institution.
For a pretrial person, contact the U.S. Marshals Service District of Idaho or review the federal case. For immigration detention, use ICE. This routing prevents a nationwide sentenced-prison locator from being presented as the answer for every federal or immigration hold in Cassia County.
