Find Federal Release Dates

Delta Federal Release Search

The Federal Bureau of Prisons inmate locator is the federal prison search source. It is not a Delta County jail roster and it is not a CDOC state-prison lookup. Use it when the person was sentenced to federal prison, moved into BOP custody after a federal conviction, or has a federal prison record from 1982 forward. If the person was only arrested locally and released from the Delta County Detention Facility, the better path is the jail, sheriff records, court docket, and VINE.

Federal custody can still matter in Delta County because a local jail release may be a transfer. A person arrested on a federal warrant or moved by the U.S. Marshals Service may leave Delta County custody without being released to the community. A local jail record may simply say transfer or hold cleared. In that situation, a BOP search, federal court records, or USMS context may explain where the person went next.

BOP Locator Fields

BOP search supports number-based and name-based routes. Research identifies BOP Register Number, DCDC Number, FBI Number, INS Number, or name as search options. Results include name, register number, age, race, sex, release date, and location. Number searches are usually cleaner when an identifier is known. Name searches need careful comparison because federal records can include common names and older custody events.

1. Open the BOP inmate locator.
2. Search by federal number if available.
3. If no number is known, search by first and last name and compare the result details.
4. Review release date and location.
5. If the release date is in the past and no location is shown, read BOP's record-meaning guidance before drawing conclusions.
6. Use local Delta County records if the question is the original jail booking or transfer out of county custody.

The BOP inmate locator is the official federal search source identified in the research.

The locator image fits federal release checks, especially when a Delta County jail record points to federal custody.

Read BOP Release Dates

BOP's record-meaning page gives a specific interpretation rule. If the listed release date is in the past and no facility location is shown, BOP says the person was released on that date and is no longer in BOP custody. A future release date reflects a projected release date based on BOP calculations. BOP also cautions that a person may still be on parole, supervised release, or in another custody or criminal-justice system.

This is different from Delta County jail release language. A BOP release date is a federal custody date. It does not prove the exact Delta County jail release timestamp, and it may not explain what happened in the local case. To connect the two, use the Delta County jail record, the local court docket, and any federal record that explains transfer, sentence, or release.

BOP's record-meaning page explains how federal release-date and location fields should be read.

The BOP explanation is useful because it distinguishes a past federal release date from a current facility location.

Delta Jail to Federal Custody

A county jail release to another agency should be read as a custody transfer until the receiving agency confirms otherwise. The U.S. Marshals Service handles federal prisoner custody between arrest, court proceedings, remand, acquittal, and delivery to BOP after conviction. USMS says many federal prisoners are placed in federal, state, local, and private jails. That means a Delta County jail event can be part of a federal custody path even when BOP is not the first record that appears.

If a Delta County jail record says transfer, ask transfer to whom. If it points to federal custody, search BOP for a sentenced federal record and use federal court or USMS context for pretrial custody. If it points to immigration custody, use the ICE Detainee Locator. If it points to Colorado state prison, use CDOC instead.

The timing can also differ. A person may leave Delta County custody before BOP shows a sentenced-prison location, especially if the federal case is still pretrial or if USMS is handling transport. In that gap, the local jail record and federal court context may explain the custody change better than the BOP locator alone.

Federal Search Limits

BOP is not a universal inmate locator. It will not show every Delta County booking, every state-prison release, or every ICE detention event. It is a federal prison locator. More detail may require a federal records request, and local Delta County details may require Sheriff's Records Management or court records. Treat each system as a separate record custodian.

For a named person who has both state and federal history, search the systems separately. CDOC records use Colorado DOC identifiers. BOP records use federal identifiers such as Register Number, DCDC Number, FBI Number, or INS Number. A similar name in two systems should be verified by identifiers and case context before the records are connected.

Delta County court records can help bridge the systems when a local case intersects with a federal matter. The docket may show a local disposition or warrant context, while the federal locator shows only the federal prison side. Neither source should be forced to answer the other's record question.

When the federal source is thin, do not force the BOP locator to answer a Delta County question. The local jail record can show when the person left county custody. The federal court or USMS context can explain why the transfer occurred. BOP can show the federal prison side after a sentenced record exists. Each source is limited to its own agency role.

That agency split is the main safeguard against a false match. A federal release date should be connected to a Delta County booking only when the jail record, court record, or federal case history supports the connection. If the local file only shows a hold or transfer, keep the wording limited to that fact until the federal source confirms custody or release.

Note: A federal release date can be accurate for BOP custody while still leaving local court, supervision, or transfer questions unresolved.
