Federal BOP Releases

Where Federal BOP Releases Go

Federal BOP custody is separate from Mendocino County custody and California CDCR custody. A person arrested in Mendocino County may have a local booking, a federal writ, a U.S. Marshals handoff, or a later federal sentence. The sheriff booking record can show that the person left county custody, but it does not determine the later federal release date. BOP's inmate locator is the public federal route for sentenced federal inmates.

The BOP locator covers federal inmates from 1982 to the present and supports search by number or by name. BOP's records guidance explains that if a listed release date is in the past and no facility is shown, release occurred on that date and the person is no longer in BOP custody. If the result says "Released" or "Not in BOP Custody" and no facility location is indicated, the person is no longer in BOP custody. BOP also warns that the person may still be in another correctional or law-enforcement system or on parole or supervised release.

The project screenshot below is a matching BOP locator image from the manifest. It is appropriate here because this page is specifically about the federal search route, and it shows the federal tool rather than a county or CDCR page.

Use the screenshot only as navigation context. Federal release dates can be recalculated, and BOP says users should check periodically because sentences are being reviewed for Federal Time Credit changes under the First Step Act.

How to Confirm a Federal Release

Use BOP when the person was a sentenced federal inmate. Use federal court or U.S. Marshals/court records for pretrial federal detention, writs, or transport questions that do not appear in BOP. Use the Mendocino jail record only to confirm the local release or transfer out of county custody.

1. Go to BOP Inmate Locator.
2. Search by number if possible: BOP register number, DCDC number, FBI number, or INS number. If no number is available, search by name.
3. Read the result carefully. A past release date with no facility generally means release from BOP custody occurred on that date.
4. If the result says Released or Not in BOP Custody, remember that this confirms only BOP custody status. Check county, state, ICE, court, parole, or supervised-release channels as needed.
5. If more detail is required, use federal records or FOIA routes rather than Mendocino County NextRequest, unless the question is the local jail handoff.

BOP Records and Contact

BOP is a federal system, so local sheriff records cannot supply the federal release date except as a transfer clue. Use BOP locator results for public federal release status. Use federal court dockets, U.S. Probation, or federal records procedures for sentencing and supervised-release context. Use Mendocino Superior Court only for state or local cases, and use Mendocino County NextRequest only for the county booking/release record.

If requesting records, be precise. For BOP or federal FOIA, include full name, date of birth, register number if known, federal case number if known, and the requested release or custody event. For Mendocino County, ask only for the local booking/release fields, such as time and manner of release or agency transferred to.

About Federal BOP

The Federal Bureau of Prisons operates the federal inmate locator for sentenced federal prisoners. It does not replace local jail rosters, CDCR, ICE, state court records, or federal court dockets. For a Mendocino County user, BOP is most useful when a person was federally sentenced, moved from local custody into federal custody, or appears to have a federal release date rather than a county or state release date.

Federal custody has several stages. A person may be booked locally, held on a federal writ, moved by U.S. Marshals, detained pretrial, sentenced in federal court, designated to a BOP facility, released from BOP custody, and then placed on federal supervised release. BOP's public locator speaks to BOP custody status. It does not explain every local booking, every court condition, or every supervised-release term.

For Mendocino County release research, always identify the system first. A person released from the Mendocino County Jail is a county release unless the record says transfer to federal custody. A person released from CDCR is a state release. A person released from ICE is an immigration custody release. A BOP release date belongs to federal custody and should not be blended with California Penal Code section 4019 county jail credits or CDCR EPRD/BPH date labels.

Federal BOP Record Limits

BOP locator data is a custody-status tool. Federal release status can be incomplete if the person moved into another system, remains on supervised release, has another hold, or has a recalculated date. Verify with BOP, federal court, U.S. Probation, or the originating agency before relying on a result.

For Mendocino County, BOP is a follow-up path only when the person was in federal custody or the sheriff record shows a federal transfer. It is not the right tool for a local jail release, a CDCR release, a Parlin Fork event, or county probation. A county jail release to federal custody means the person left the sheriff's custody, not necessarily all custody.

BOP says its public records run from 1982 forward. If a listed release date is in the past and no facility is shown, the person is no longer in BOP custody. If more detail is needed, use federal court records, federal supervision contacts, or federal records procedures rather than the Mendocino County sheriff.
