Federal Bureau Release Paths
No BOP prison was verified within Marshall County. “Federal Bureau of Prisons facilities nationwide” therefore describes the national system that may hold a federally sentenced person from Marshall County, not one local building. The federal path begins with proof of federal jurisdiction. A Marshall County Jail release sheet may identify a federal detainer or receiving authority, and the federal criminal docket can show the charge, detention order, judgment, and sentence.
A person leaving BOP can enter the community at sentence completion, begin court-ordered supervised release, or move to another custodian. Supervised release is a federal court sentence component overseen in the community, not BOP incarceration. A transfer to a county jail or immigration authority is also not community release. The most useful BOP result combines a release date with the location or status wording, but the next custodian must still be checked.
“Released” means BOP custody ended. It does not rule out supervision, another criminal-justice custodian, or immigration detention.
Search Federal Bureau Release Records
The official BOP inmate locator covers federal inmates from 1982 forward. An identifier search is the strongest route because it reduces same-name errors. The name route can be narrowed with age, race, and sex, but those fields should be used to distinguish results, not to guess an identity. Compare the register number and known case facts before relying on a match.
- Choose an identifier search when a BOP Register, DCDC, FBI, or INS number is available.
- If no number is known, enter the person's first, middle, and last name as accurately as the federal record allows.
- Use age, race, and sex only to narrow possible name matches.
- Open the correct result and record the name, register number, release date, and location or status exactly as displayed.
- Compare the result with the federal docket and check for another custodian or supervision after BOP custody.
The captured federal inmate locator search shows the official nationwide lookup used for a Marshall County federal custody question.
The locator is a BOP source. It should not be read as a Marshall County Jail roster or as proof that every federal arrestee has reached a BOP institution.
Federal Bureau Release Result Fields
A BOP result provides a compact custody summary. Preserve each field's label because a release date is not the same as the date of a court order, transfer, or supervision start. A location name supports current BOP placement. “Released” or “Not in BOP Custody” indicates that BOP no longer holds the person, but the wording does not describe every event that followed.
| BOP field | What it establishes | What it does not establish |
|---|---|---|
| Name | The name attached to the BOP result | Identity without other matching facts |
| Register number | The federal offender record identifier | A Marshall County booking number |
| Age, race, and sex | Details used to distinguish possible matches | The person's present location by themselves |
| Release date | The date BOP reports for its custody record | The end of court supervision or another hold |
| Location or status | A BOP facility or BOP custody outcome | Custody held by a county, USMS, or ICE |
A result outside the 1982-forward coverage may require archival work. A no-result response can also reflect spelling, identity, or a custody path that never became BOP imprisonment. Database silence should not be converted into a release conclusion.
Note: Keep the BOP register number with the result because names alone can produce mistaken matches across the nationwide system.
BOP Not-in-Custody Limits
“Not in BOP Custody” is an agency boundary. It can be accurate even when the person remains under a federal court's supervised-release term. It can also coexist with state or county custody after a new case, warrant, or detainer. When a Marshall County record identifies a federal handoff, trace the receiving authority instead of assuming the BOP result proves a return to Lewisburg or to the community.
Release-date displays may change when BOP recalculates time under the First Step Act or corrects the sentence computation. A displayed future date is not the physical release event. Court action, earned-time application, another hold, or computation review can alter what appears. Record the date on which the locator was checked, keep the exact field label, and seek the underlying BOP record when the final event matters.
Note: A federal release date and a supervised-release end date answer different questions and should never be substituted for each other.
USMS Custody Before BOP
A federal defendant may be detained before sentence without appearing as a prisoner at a permanent BOP facility. The U.S. Marshals Service commonly uses local and contract detention while a case is pending. Those placements can change. The official USMS prisoner-operations material explains that Marshals manage federal detainees during this stage, but USMS does not offer a public historical release locator comparable to BOP's tool.
The federal court docket is central for this gap. It may show the detention or release order, bond conditions, judgment, sentence, and later supervision action. A court order authorizes the legal outcome, while the custodian's record shows when and where the physical movement occurred. The Marshall County clerk directory helps separate the local case record from the federal docket. If the Sheriff release sheet lists USMS or another federal recipient, request the receiving-custody event rather than searching only BOP.
| Federal stage | Best starting source | Question answered |
|---|---|---|
| Local arrest with federal hold | Marshall County release/transfer sheet | Which authority received the person |
| Federal pretrial detention | Federal docket and USMS channel | Detention or release authority |
| Sentenced BOP imprisonment | BOP locator | BOP location, status, and reported release date |
| After BOP custody | Federal docket and receiving authority | Supervision or continued custody |
Request Federal Bureau Release Records
The locator is a discovery tool, not the full release file. When an exact federal event is needed, request the existing record maintained by the responsible federal office. Supply the full name, BOP register number, known federal case number, approximate custody dates, and a narrow description. Ask for the recorded release date and type, releasing institution, sentence-computation record when relevant, and any receiving authority or detainer disposition that can be released.
A good request seeks records rather than an agency-created explanation. For example, ask for the existing release authorization, custody-status entry, or equivalent record for the named person and BOP number. If the locator date changed, request the record that reflects the final calculation or release event. Do not treat a projected field as the actual gate date.

Coverage: 1982 forward
The Marshall County Sheriff’s Department, led by Sheriff Billy Lamb, remains the source for its own transfer record at the start of a federal handoff. The Sheriff is at 209 North First Avenue in Lewisburg and can be reached at 931-359-6122. A request can follow the office's official records policy. That local document may identify USMS, BOP, ICE, or another recipient, which prevents a search from starting in the wrong federal system.
Note: Request the receiving-authority field from Marshall County when the federal custodian is unclear at the start of the transfer.
Separate Federal Release Systems
BOP, USMS, and ICE answer different custody questions. BOP manages sentenced federal prisoners and publishes the 1982-forward locator. USMS handles many pretrial movements and contract placements without a comparable public historical locator. ICE runs an immigration detainee system. One agency's release label does not resolve another agency's custody.
If a BOP result ends but the record points to immigration custody, use the ICE detention system page to understand the separate recent-release window and its limits. If the person instead returns to a Tennessee county, seek that county's booking and release record. The receiving agency is the next link in the chain.
- BOP release
- The end of Federal Bureau of Prisons custody.
- Supervised release
- A federal court term served in the community after imprisonment.
- Federal detainer
- A federal hold or request that can affect transfer or release.
- Contract detention
- A non-BOP site used to hold a person for a federal authority.
Confirm Marshall Federal Releases
For a Marshall County person, build the record from both ends. Start with the last confirmed local or federal custodian. Obtain the Marshall County Jail transfer sheet if the path began there. Match the BOP register number and federal case facts. Then preserve the BOP result and locate the related court order or judgment. If another authority appears, confirm that authority's receipt and later release.
The broader Marshall County released-inmate search explains how county jail, Tennessee correctional, court, federal, and immigration records fit together. That route is useful when federal jurisdiction is suspected but not yet established. It keeps a BOP search from being mistaken for a county-jail search and prevents “Not in BOP Custody” from becoming an unsupported claim of full release.
