Which system is holding them?

There is no single search that covers everyone in Blaine County. Match the situation to the right official locator — most families start with the first one.

If the arrest was recent

Start with the local jail

For a recent local arrest, check the arresting jurisdiction’s official jail roster or custody-notification service. Housing may be at a municipal, county, regional, or contracted facility. If no record appears, ask the arresting agency or jail how to confirm the booking; do not infer the destination from distance or a facility listing.

The current county Sheriff page publishes this general Sheriff contact. Ask whether the person is in county detention custody and where to follow up.

Blaine Sheriff custody assistance

Call the published contact within its stated role and ask about custody, release or the appropriate receiving agency. A fresh police arrest may precede jail booking. The number was not called.

Published telephone assistance, not an answered-line or individual-record check. No online search is claimed by this phone route; municipal police holding and a transfer can require another contact.

Find Montana county sheriff contacts

For a recent local arrest, contact the arresting agency or responsible county sheriff. Montana DOC VINE does not establish county-jail booking coverage.

Select your county in the government-identified sheriffs association directory. Use the sheriff’s own jail/custody process; directory listings do not certify a booking hotline or current custody.

Search Montana participating-agency custody — Montana VINE covers adult felony offenders under DOC supervision, including prison, probation/parole and community DOC programs. County-jail booking coverage is not established.

If nothing appears, contact the arresting agency or the responsible jail to ask how to confirm booking. A missing record does not prove release, and an agency may limit what it can disclose.

If they were sentenced to prison

Use the correctional locator

For a state-prison sentence, use the Montana correctional locator. A short jail sentence may still be served in a local or regional jail. A sentence alone does not establish the housing location; confirm with the responsible agency.

Montana DOC jurisdiction; local bookings need a separate route

If the charge is federal

Search the Federal Bureau of Prisons

A federal charge does not tell you which building holds the person. The U.S. Marshals Service is responsible for federal pretrial detention and may use local, state, private, or federal facilities. Check the Federal Bureau of Prisons locator, but a missing result does not establish that the person is not detained. For a recent federal arrest, contact the arresting agency or the relevant U.S. Marshals district office to ask about the appropriate custody-information process. USMS is a contact route, not a public person locator, and disclosure of a location is not guaranteed.

Other kinds of custody

Immigration detention has a separate official ICE detainee locator. It does not search for people under 18, and a missing result does not prove release; use the official ICE field-office contacts. Search by A-number and country of birth, or the name/country/date-of-birth information requested by the service. Access and disclosure can be restricted.

Juvenile and tribal custody may have different agencies, privacy rules, and search limits. This guide does not provide a comprehensive juvenile or tribal locator. Contact the arresting agency or responsible juvenile or tribal authority to confirm the correct process.

For federal pretrial detention, use the U.S. Marshals district directory. Federal responsibility can include housing in a local jail.

Commercial bail available

Release depends on the court’s order. A payment is not required in every case. Ask the court which secured-bond options, if any, are permitted; a private commercial bond service has separate fees and conditions. Confirm the process before paying anyone.

The person’s rights. The person in custody has the right to talk to a lawyer about their case, and if they cannot afford one, the court can appoint a public defender.
