Madison County ICE Transfer Route
The MCSO detention page expressly includes immigration detainees among the populations served by Madison County Detention Center. That local fact makes destination the key release-record field. When MCSO custody ends, the person may leave for the community, ICE, another county, IDOC, or another agency. A roster disappearance cannot distinguish those outcomes.
ICE detention is a federal civil immigration system. It is not the same as BOP custody for a federal criminal sentence. A person can move from a county criminal hold to ICE civil custody, and both records can accurately use release language for their own agency. The county record should identify the receiving agency or destination. The ICE record then addresses the next stage.
| Event | Correct source | Limited fact proved |
|---|---|---|
| MCSO custody ends | County release or transport record | Date, disposition, and destination recorded by Madison County |
| ICE assumes custody | ICE locator or ERO confirmation | ICE-reported detention status |
| ICE custody ends | ICE locator, ERO, or federal record | End of ICE custody, not every other authority |
| County case outcome | Madison County court record | Criminal-case authority and disposition |
Search the ICE Detainee Locator
Use the official ICE Online Detainee Locator System. The strongest route uses the person's A-number and country of birth. An A-number is the federal immigration identification number. Enter the exact nine-digit form; when the number has eight digits, the researched ICE instructions call for adding a leading zero. A biographical search uses exact first and last name, country of birth, and an optional birth date.
- Obtain the A-number from a reliable document when possible.
- Enter the number in nine-digit form and select country of birth.
- If no number is available, use exact biographical spelling.
- Compare the result with the person and Madison County transfer date.
- Record the ICE status, location information, and time checked.
- Contact ERO when a recent transfer has not resolved the question.
ODLS does not display people under 18. Very recent transfers, protected cases, spelling differences, data issues, and identifier errors can also limit results. A blank result is not a release certificate.
Madison County ICE Release Fields
The county and federal systems hold different fields. Ask MCSO for the booking number, county release timestamp, release or transfer disposition, holding agency, and receiving agency. In ICE, preserve the exact person match and the federal status supplied by the live interface. Do not merge a county release time with an ICE release date.
| Field | How to use it |
|---|---|
| A-number | Match the federal immigration record |
| Country of birth | Required with an A-number search |
| Exact name and birth date | Biographical fallback and identity check |
| MCSO release timestamp | End of Madison County custody |
| Receiving agency | Evidence that the event was a transfer |
| ICE-reported status | Federal civil-detention information within ICE's scope |
ICE states that ODLS can include current detainees and people released from ICE custody within the last 60 days. That makes it a useful recent federal channel, but also a short-window one. An older release can fall outside the public result even though the historical event occurred.
ICE Detainers in Madison County
An ICE detainer is a request that a jail notify ICE before ordinary release and maintain custody for up to 48 additional hours so the Department of Homeland Security can assume custody. It is not itself a Madison County sentence or proof that ICE actually took custody. The county disposition and later ICE result should be read together.
A bond or release order in the Madison County case may resolve the local criminal basis while an immigration transfer still follows. The order proves legal action in the court case. The MCSO release line proves when county custody ended. The ICE locator or ERO contact addresses whether federal civil detention began.
Contact ICE After Transfer
When ODLS does not answer a recent transfer, contact the appropriate Enforcement and Removal Operations office with the person's full identifiers. ICE's Detention Reporting and Information Line is 1-888-351-4024. The researched schedule is Monday through Friday, excluding holidays, from 8 a.m. to 8 p.m. Eastern. Confirm current hours on the official ICE site before relying on them.
Prepare the A-number, exact name, aliases if documented, date and country of birth, Madison County booking number, approximate transfer date, and the MCSO destination response. Staff may limit disclosure. Ask which office or facility controls the current inquiry rather than assuming a location from geographic proximity.
The ICE detention-management information explains the federal detention context and contacts. It does not turn ODLS into a certified county release record. Keep the MCSO response with the federal result.
Request Madison County Transfer Records
Use the official Madison County Records Request portal for the local custody episode. Identify one person and booking date. Ask for booking and release timestamps, the disposition code, holding agency, receiving agency or destination, and the available release or transport document. Request a cost estimate before chargeable work because the reviewed MCSO pages publish no flat booking-record fee.
Idaho public-record procedure governs the county request, while federal access procedures govern ICE records. Do not send an Idaho Public Records Act demand to ICE and treat the wrong procedure as proof that no federal record exists. If MCSO redacts part of its record, ask for the statutory basis and reasonably segregable nonexempt facts.
The Madison County court file should be obtained through iCourt or the filing-county clerk under Idaho Court Administrative Rule 32. It may show bond, dismissal, judgment, commitment, or another order, but it will not necessarily show the exact ICE intake time.
Madison County Multi-Hop Custody
MCSO's service list includes Rexburg Police, immigration detainees, Saint Anthony Work Camp, Teton County, and neighboring counties. This makes Madison County a multi-hop custody setting. The phrase “left Madison” is incomplete until the destination is known.
Build a dated chain. First record when MCSO custody ended. Next identify the destination. Then search the receiving system. If ICE later reports release, check whether a state, county, or federal criminal authority remained. Each agency can end its own custody without ending every legal process.
- Community release
- The person leaves the named custodian without a recorded transfer to another jail or detention agency.
- Transfer
- Custody moves from one agency to another.
- Detainer
- A request tied to notification and possible short continued custody for transfer.
- ERO
- ICE Enforcement and Removal Operations, the operational office for detention inquiries.
ICE Versus BOP Release Searches
ICE and BOP should never be treated as one federal locator. ICE handles civil immigration detention and uses ODLS. BOP handles federally sentenced prison custody and uses the BOP Inmate Locator. USMS commonly handles federal criminal pretrial custody and transport. The last known authority determines the tool.
| System | Search key | Result scope |
|---|---|---|
| ICE | A-number plus country of birth, or exact biography | ICE civil detention and recent ICE release information |
| BOP | Federal identifier or name | Federal sentenced-prison custody and release status |
| USMS | Federal case and agency contact | Federal pretrial custody and transport |
| MCSO | Booking identity and date | Madison County custody and transfer disposition |
“Not in BOP custody” cannot answer an ICE question. Likewise, no ODLS result proves that a person was never held by BOP or a county. Search the system named by the source record.
Verify ICE Release Identity
Use more than a common name. Match the A-number, country and date of birth, Madison County booking number, and transfer date. Transliteration, spacing, compound names, and aliases can affect a biographical search. An old booking photo alone is not a safe identity key.
When records conflict, compare the custodian and date. MCSO can accurately report transfer on one day while ICE reports a later release. Those are consecutive events. Preserve both. A locator absence after 60 days can also reflect the public window rather than an error in the historical county record.
If the identity remains uncertain, request the county record and contact ERO with the documented identifiers. Do not attach one person's federal result to another person's Madison County booking merely because the names resemble each other.
ICE Release Proof Boundaries
An ODLS entry supports ICE-reported detention or release information. It does not prove the end of a Madison County case, state sentence, BOP custody, or every form of federal authority. A Madison County release record supports the end of county custody. It cannot certify what happened throughout the later ICE process.
A missing ICE result can mean recent movement, removal, transfer, identifier mismatch, age restriction, protected data, or the end of the public window. Ask ERO rather than converting absence into a firm conclusion. Keep a checked-on date for every locator result.
No ICE detention facility is identified as located in Madison County by the research. The local connection is MCSO's documented housing of immigration detainees and possible transfer out of county custody. Do not invent a local ICE release desk, release hour, exit door, or family waiting area.
Madison County ICE Contact Point
For the county portion, Madison County Detention Center is at 145 E Main St, Rexburg, ID 83440. The jail line is 208-372-5002. Ask whether the person remains held, when MCSO custody ended, and whether the record names ICE or another destination.
That jail can address its own booking and release record. It does not control the later ICE locator, federal detention location, or federal release decision. For the full county search and records sequence, use the Madison County released inmate search, then continue into ICE only when the county or another reliable source points there.
