Federal Prison Releases
BOP covers federal inmates incarcerated from 1982 to the present. The research source says that if a listed release date is in the past and no facility location appears, the release occurred on that date and the person is no longer in BOP custody. BOP also cautions that the person may still be in another justice system or under federal supervision, so the BOP result should be read as a federal custody result only.
How to Search BOP
Use the official BOP inmate locator. Search by BOP register number when known, or by name and identifying details. If the case began with a Kiowa arrest, also check Kiowa County Combined Court and the local jail record to see whether the person was transferred or whether the federal record belongs to a different case.

For more detail than the locator provides, use the federal records request route described by BOP/USAGov. Use local agencies only for local arrest, jail, and court documents.
About the Federal Edge Path
No federal prison was found in Kiowa County. Federal lookup belongs on this site because a local release can be followed by federal custody or because a separate federal sentence may explain why a person does not appear in county or CDOC results.

BOP Fields to Read
The BOP locator is strongest when searched by a federal register number, but name searches can work when the identifying information is specific enough. Read the person's name, register number, age or identifying details, facility location if any, and release date or custody status exactly as displayed. BOP's records explanation says that when the listed release date is in the past and no facility location appears, the person is no longer in BOP custody. That is a federal custody statement. It does not say whether a person is in state custody, local custody, immigration custody, or under a separate court process.
U.S. Marshals Context
Federal pretrial custody often runs through the U.S. Marshals Service rather than BOP. The research explains that people arrested or detained on federal statutes are brought before a magistrate or judge for an initial hearing; after the hearing, they may be released or remanded to Marshals custody, and if convicted, the Marshals deliver the prisoner to the institution for the imposed sentence. BOP is therefore most useful after a federal sentence, not as a complete public lookup for every federal hold or pretrial transfer.
Limits of the Federal Locator
No federal prison was found in Kiowa County, so this page should remain an edge route. Use it when a warrant, court record, jail transfer note, attorney information, or family information points to federal custody. Do not use BOP to confirm an ordinary Bent County Jail bond release or a Colorado DOC release. For a Kiowa local case, the release trail still begins with the holding jail and the court unless federal facts are present.
Records After a BOP Result
If the BOP locator shows a past release date, verify whether another system now controls the person. Federal supervision information may require federal court context. State prison or parole status belongs in CDOC. Local bond or disposition records belong with Kiowa County Combined Court. Immigration custody belongs in ICE ODLS. If more federal detail is needed than the locator provides, use the federal records request route described by BOP or USAGov and ask for the specific public custody or release information needed.
Federal Record Boundaries
BOP records are federal correctional records. They do not replace Colorado court, county jail, CDOC, probation, or ICE records. A BOP release date can be strong evidence that the person is no longer in BOP custody, but it should be read only within the federal prison system. If the person has a Kiowa County case, the local court and jail records may still explain the original arrest, transfer, or state-local status.
Federal pretrial handling can involve the U.S. Marshals before BOP. A person may be released after an initial hearing, remanded to Marshals custody, later sentenced to BOP, or never enter BOP at all. That is why the BOP locator is an edge path for sentenced federal custody, not a complete answer for every federal-looking entry.
Kiowa Release Decision Tree
Use a decision tree instead of assuming one database answers every release question. If the person was recently arrested on a Kiowa County matter, begin with the Bent County inmate-info feed and use the arresting-agency filter for KIOWA COUNTY SO or KCSO when available. Read the booking number, date booked, arrest location, status, release date, charges, and current-custody setting. If the feed is unavailable, inconsistent, or urgent, call Bent County Jail or Bent/Kiowa Dispatch at the jail contact number and document the answer given.
If the question is why the release happened, move to Kiowa County Combined Court. The court can explain bond, recognizance release, dismissal, sentence, probation, jail credit, mittimus to DOC, warrant action, and sealing. If the court record shows probation, use Kiowa County Probation and the court order. If the court or jail record shows DOC, DOC Parole, prison sentence, or transfer to state custody, use CDOC offender search and parole-board resources. If the facts point to federal custody, use BOP only for the federal prison track and remember that U.S. Marshals custody can come before BOP. If the facts point to immigration custody, use ICE ODLS and keep county release separate from community release.
When online sources do not match, request records from the agency that controls the disputed field. Ask Bent County Jail for jail booking and release fields, Kiowa Sheriff for local incident or arrest records, the court for orders and dispositions, CDOC for prison or parole fields, BOP for federal prison records, and ICE for immigration custody routing. Keep every request narrow, factual, and tied to custody verification or correction so the custodian can identify the public record being requested.
