Mineral County Inmate Search: Finding Someone Held in Superior

Deputies, state troopers and Forest Service officers bring every adult they arrest to the county jail, 310 River Street, Superior, MT 59872. The Sheriff's Office runs it, and a 2022 state report listed 28 beds. Below, learn about finding someone, the charges, visits, deposits, letters and release day.

Start with this inmate lookup. Whatever it shows, the Superior jail itself has the final say.

Phone 406-822-3555 with the legal name and birth date, and politely ask for the jail, since 911 dispatch answers there too. Ask whether the person is held and the next court date. Bail is explained on our bail page, and the path from Justice Court to District Court on our court page.

Search for an Inmate or Active Arrest Warrant in Mineral County

2. The name didn't come up. What now?

A blank search result can mean several things:

  • Brand new. Booking, fingerprints and photos eat up time after an arrest.
  • Out already. Release could have come through bail or a signed promise.
  • Moved. Another county's lockup, a state program or federal custody might have them now.
  • Spelling. A nickname, a hyphen or a married name can throw off a search.
  • Age. Anyone under 18 goes through youth channels, not the adult jail.

When in doubt, call the jail at 406-822-3555. Staff can confirm who is inside.

3. Why does the Superior jail hold people from other places?

The jail reopened in 2021, and it has housed prisoners for other agencies as well as its own. In June 2021, for example, the sheriff reported 16 inmates, and 9 of them were Mineral County cases. The county also works with federal marshals under a formal agreement.

So the person next to your loved one might be held for a different county, a state agency or a federal case. If your loved one was arrested somewhere else and brought here, ask the jail at 406-822-3555 which agency controls the hold. That agency decides on transfers and release.

4. Could another jail nearby have them?

Adults arrested in this county stay in Superior unless they are moved. If the arrest happened close to a county line, also try these jails:

Idaho lies just west along I-90. For an arrest on the Idaho side, call that county's sheriff.

5. How can I learn about a recent arrest?

Montana treats basic arrest facts as open to anyone. Under state law, first arrest reports, mugshots, bail paperwork and the jail's daily population list all count as public (MCA 44-5-103). Anyone may ask for them.

  • Phone the Sheriff's Office at 406-822-3555 and ask how to request booking details.
  • For a written request, the office fax is 406-822-3562, and its mail goes to PO Box 99, Superior, MT 59872.
  • Investigation files are different. The same law keeps those confidential.

For a full state criminal history, Montana's Department of Justice runs a paid search called CHOPRS at app.mt.gov/choprs.

↑ Back to the question list

6. Can I get a Mineral County booking photo?

Usually, yes. Mugshots are public records in Montana (MCA 44-5-103), and state law lets that public information be passed along freely (MCA 44-5-301). Call the Sheriff's Office at 406-822-3555 to ask how to get one.

  • Photos taken during an investigation, and fingerprints, are kept confidential.
  • For an immigration booking photo, file through the ICE FOIA portal.
  • Federal mugshots are generally not handed out, though the U.S. Marshals sometimes release one for a fugitive.

7. How will I hear when they walk out?

For a stay in the Superior jail, the most reliable way is to keep in touch with jail staff at 406-822-3555.

  • VINE sends free calls, texts or emails about adult felons the state Department of Corrections supervises. Sign up through VINELink or by dialing 800-456-3076. Nobody is enrolled automatically.
  • Partner assault, choking, stalking and protection order victims get a heads-up from the jail once the accused posts bail (MCA 46-9-108).
  • Crime victims can also reach the county's victim advocate at 406-531-9976.
↑ Back to the question list

8. What are they charged with?

Ask jail staff to read the charge to you. Write down any Montana law number they mention, such as 45-6-301 for theft, and look it up on the state Legislature's Montana Code Annotated pages.

Once the prosecutor files, every count is spelled out in the court record. Misdemeanor files are on the justice and town court portal. For felony files, go to the District Court portal. The final list of counts is the call of the County Attorney's Office. It is at 300 River Street, Superior, MT 59872, 406-822-3535.

↑ Back to the question list

9. Can they get out before trial?

Often. The release decision comes at the first court appearance, typically before the Justice Court, 300 River Street, Superior, MT 59872, 406-822-3550. Judges here must choose the gentlest release terms that will still work.

  • Many misdemeanors start from a statewide recommended bond list.
  • Felonies get an amount picked by the judge.
  • Partner assault and protection order charges require a judge before release.
  • A warrant issued elsewhere blocks local bail.

Our bail page explains paying, bondsmen and refunds.

10. Who will defend my loved one?

A judge explains the right to counsel at the first court visit. Montana's public defender handles felonies and youth cases. It also takes misdemeanors that carry possible jail. The office serving this county is in Missoula:

Hiring a private attorney is another choice. Ask jail staff how a defense lawyer arranges a private meeting or call.

↑ Back to the question list

11. When is the next hearing in their case?

Ask the court holding the case:

  • Justice Court, also home to Superior town cases: 406-822-3550. General appearances are Monday afternoons and Thursday mornings.
  • Alberton Town Court, 607 Railroad Ave., Alberton, MT 59820: 406-722-3404.
  • Clerk of District Court for felonies: 406-822-3538.

Upcoming hearings may also turn up when you type the name into the state court portals. Each hearing type is explained on our court page.

12. How do I learn if there is an active warrant in Mineral County?

All warrants in the county go through the Sheriff's Office, because no town here keeps its own police. Ask deputies about one at 406-822-3555. Charges already on file turn up through the justice court search and the felony court search. State corrections marks its escapees and absconders on the DOC offender lookup. Before facing a warrant, call a lawyer. A lawyer can help arrange a surrender at 310 River Street, Superior, MT 59872, or a new date with the court that issued it. For a Justice Court warrant, call 406-822-3550.

13. Can I visit someone in the Mineral County jail?

Yes, family visits happen, and detention officers supervise them. Rules can change, so call 406-822-3555 before you make the drive. Good questions to ask:

  • What days are visits allowed, and do I need to book a slot?
  • Which kind of ID works, and may kids come along?
  • Is there a dress code, and where do I leave my phone and bag?
  • Are video visits offered?

Our visitation guide has broader advice for a first trip to see someone behind bars.

14. How do deposits to an inmate account work?

A jail account usually covers commissary items like snacks and soap, plus phone time. Call 406-822-3555 and ask how deposits work right now, what limits apply and whether fees are charged. Have the person's full name and any ID number ready.

Deposit options in general are explained in our money transfer guide, and store items in our commissary guide. Never put bills in an envelope.

↑ Back to the question list

15. Can they call me, or send messages?

The jail decides how inmate calls are set up. Phone 406-822-3555 and ask how your loved one can call you, what it costs, and whether tablets or messages are offered. Ask whether calls are recorded.

Save any talk about what happened for their attorney. See our inmate phone guide and our inmate messaging guide for more.

↑ Back to the question list

16. What address do letters go to?

The Sheriff's Office uses PO Box 99, Superior, MT 59872 for mail. Before you send anything, call 406-822-3555 and ask how to address a letter to an inmate and whether to add an ID number. Also check the rules on photos and reading material.

Write the inmate's legal first and last name, and show your return address. Typical jail mail rules are in our inmate mail guide. Never tuck cash inside.

↑ Back to the question list

17. Can family collect their belongings?

Whatever was in their pockets at booking is kept by the jail until they leave. If you are picking things up for your loved one, call 406-822-3555 first and ask whether a signed release form is needed. Then bring photo ID to 310 River Street, Superior, MT 59872.

If the person will be out of town when released, ask whether someone else may collect their things.

↑ Back to the question list

18. What should I plan for on release day?

Detention officers handle discharges and transfers, and they arrange transport when someone moves to another facility. Ask the jail at 406-822-3555 about what time a release is likely.

  • Superior is a small town, so plan a ride home ahead of time.
  • Ask about any medicine your loved one will need on the way out.
  • Get a copy of the release order. It lists the rules they must follow, such as no-contact orders or check-ins (MCA 46-9-110).
↑ Back to the question list

19. Will the jail get them medical care?

Detention officers hand out medications and take inmates to medical checks. When needed, they escort people to outside clinics or hospitals. Call 406-822-3555 as soon as you learn your loved one is ill, injured or out of a needed prescription.

Share the drug names, doses and the doctor who prescribed them, with that doctor's phone number. For a life-threatening problem, dial 911. Mention it plainly if you worry about their mental health.

↑ Back to the question list

20. What changes when federal agents bring the charge?

A federal arrest here leads to the Missoula federal court at the Russell Smith Federal Courthouse, 201 E. Broadway, Suite 310, Missoula, MT 59802, 406-542-7260.

  1. At the opening federal appearance, a detention hearing settles custody until trial (18 U.S.C. 3142).
  2. The U.S. Marshals Service keeps custody until trial. The Superior jail has an agreement with the Marshals, but people may be held in other jails too. Ask the Marshals at 406-200-6004.
  3. Search the case on PACER.
  4. After sentencing, look them up on the Federal Bureau of Prisons inmate locator.

21. What if ICE places a detainer?

An immigration hold follows these steps:

  1. Immigration officers deliver a detainer on Form I-247A.
  2. Your loved one can then be kept up to 48 hours after they would otherwise be released. Montana makes officers honor that hold, except for someone with solid proof they are a citizen or here lawfully (MCA 27-16-801).
  3. Agents move the person into the custody of ICE's Salt Lake City Field Office, 2975 Decker Lake Drive, Suite 100, West Valley City, UT 84119, 801-736-1200.
  4. Try the ICE Online Detainee Locator. Enter an alien registration number, or else the name as ICE recorded it plus the birth country. If the search comes up empty, phone the Salt Lake City office.

22. How do I track a Mineral County inmate sent to prison?

A state prison sentence doesn't mean an instant move. Your loved one may sit in Superior for a while until state staff evaluate them. Even during that wait, their name may be listed by the state.

↑ Back to the question list

23. Where do Mineral County youths go after an arrest?

Teens are kept out of the Superior jail except for a short wait, and even then adults can't see or hear them (MCA 41-5-349). Youth Court takes over, and its records stay private.

Locked detention triggers a hearing before a judge by the next business day (MCA 41-5-332). To find out where the youth is, call Missoula County Youth Court at 406-258-4735, which has a probation officer for this county. One licensed youth center nearby is the Missoula County Juvenile Detention facility, 2340 Mullan Road, Missoula, MT 59808. Ask the youth court whether that is where the teen was taken.

24. Who does the policing across Mineral County?

The Census Bureau counts 5,185 residents as of July 1, 2025. Officers from these agencies may make an arrest:

  • Mineral County Sheriff's Office, 310 River Street, Superior, MT 59872, 406-822-3555. It is the main police agency for the whole county, including Superior and Alberton under contract, plus St. Regis, De Borgia, Haugan, Saltese, Tarkio and Cyr.
