The Sheriff keeps the list as one plain table on the office's own web page. To search it from any device:

1. Open the Sheriff's roster.
2. Read the "updated" date shown above the names. If that date is several days old, a phone call will give you a newer answer.
3. Search the page for the surname. Most phone browsers hide this under a menu item called "Find," and computers use Ctrl+F.
4. Scan that row for the photo, booking date, arresting agency, age and charge.
5. Note the charge and the booking date. Having both makes the phone call quicker.

Bail amounts and hearing times come from staff by phone. Call 218-745-5411 on weekdays from 8:00 a.m. to 4:30 p.m.

It is normal for a fresh arrest to be absent for a while. A few things can cause that:

• The list hasn't caught up. It is often refreshed only once a day, so a late-night booking may not show until later.
• They got a ticket instead. For many smaller crimes, a deputy hands over a citation that lists a hearing day, and the person heads home.
• A judge already let them out. Release can come at the first hearing, which often takes place over a video link.
• They are in a different jail. Police in a neighboring county may have made the arrest. The Sheriff can also transfer someone to a jail outside the county when that is needed.
• A typo or a second name. Search again using their middle name, nickname or former surname.

Deputies can give you a sure answer. Phone 218-745-5411.

The county has one jail. It is the county jail in Warren, 208 E Colvin Ave., Suite 1, Warren, MN 56762, 218-745-5411. The state Department of Corrections licenses it to hold up to 14 men and women, and its approval runs from November 1, 2026, to April 30, 2027.

The jail shut for a remodel in 2024. While the work went on, the Sheriff housed people at the Pennington County Jail in Thief River Falls. The Warren jail is open again, but the Sheriff may still send a person to a jail in a different county when space or safety calls for it. Always ask where they are tonight.

When the arrest happened close to a border with another county, or a transfer took place, try these jails as well:

• Pennington County Jail, 102 1st Street West, Thief River Falls, MN 56701, 218-681-6161
• Northwest Regional Corrections Center, the regional jail in Polk County, 816 Marin Avenue, Suite 110, Crookston, MN 56716, 218-470-8100 (pick the menu choice for prisoner questions)
• Kittson County Jail, licensed as a 90-day lockup, 410 S Fifth Street, Suite 102, Hallock, MN 56728, 218-843-3535

Some people sentenced for nonviolent crimes can cut jail time by working on a Sentence to Serve crew, a program shared with Pennington County. Its line is 218-683-7001.

Yes. The Sheriff's jail roster shows mugshots. A booking photo sits in its own column right next to each name.

Minnesota's Data Practices Act lets anyone see a booking photo. An agency may delay releasing one while it would damage an active investigation (Minn. Stat. 13.82, subd. 26). Need a photo the roster no longer shows, or one taken by a different agency? Request it from whoever made the arrest. For a deputy's arrest, that means the Sheriff's Office at 218-745-5411.

• To get an immigration booking photo, use the ICE FOIA records form.
• Photos from a federal booking usually don't reach the public. The U.S. Marshals Service sometimes shares one while searching for a fugitive.

Minnesota's Department of Public Safety runs VINE. It follows custody changes at county jails. Once you register, it can alert you if the person is released or moved to another jail.

• Sign up on VINELink for Minnesota, or call 877-664-8463.
• Nobody is signed up for you. Each person who wants alerts has to register.
• Once a person moves to a state prison, VINE alerts end. The Department of Corrections handles those through Minnesota Haven.

Victims and witnesses can get help with safety and release news from county Victim Services, 208 East Colvin Ave, Suite 2, Warren, MN 56762, 218-745-5523. That number is also a crisis line.

When deputies arrest someone with no warrant and keep them locked up, a judge has to see that person within 36 hours. When counting, skip the calendar date of the arrest, plus any Sunday or legal holiday (Minn. R. Crim. P. 4.02). That first hearing is in District Court in Warren and often happens on a video screen. Court administration sits at 208 E Colvin Ave, Suite 18, Warren, MN 56762, 218-745-4921.

• The starting point is release. The judge's first choice under Rule 6.02 is freeing the person on their word, with only the conditions that keep the public safe and bring them back for hearings.
• Expect two numbers. Rule 6.02 also requires a cash figure that comes with no strings attached. So an order often lists a lower bail with rules, like no alcohol, and a higher one without rules.
• Cash bail belongs to the defendant. It can go toward fines first. Family who paid it get money back only if the defendant signs court form CRM602 (Minn. Stat. 629.53).
• Bond agents charge a fee. Agents need a state license, and under Minn. Stat. 60M.02 their fee is $100 or more. That fee is kept by the agent even after the case ends.

Where to pay depends on the day and time, so ask jail staff at 218-745-5411 before you drive. Our bail guide has more, and the Minnesota bail laws page covers the state rules.

Each roster row lists the charge. Once a prosecutor files charges, the case shows up on Minnesota Court Records Online, the state's free case search. Type the person's name to find it. Some youth records do not appear there.

State law (Minn. Stat. 609.02, 609.03) puts every crime in one of four groups. Here they are, lightest first:

• Petty misdemeanor: no jail, and the fine tops out at $300.
• Misdemeanor: up to a $1,000 fine and 90 days locked up.
• Gross misdemeanor: up to a $3,000 fine and 364 days locked up.
• Felony: the judge could order a year or longer in state prison.

Court staff can help you find a case by phone. Reach court administration at 208 E Colvin Ave, Suite 18, Warren, MN 56762, 218-745-4921.

If the person charged has no money for a lawyer, a judge can assign a public defender. This is true for any felony or gross misdemeanor, and for a misdemeanor that could end in a jail sentence. The judge decides after the person fills out a short form about money. Under Minn. Stat. 611.14 and 611.17, people already on need-based help, such as food or cash aid, are presumed to qualify.

Speak up about it at the very first hearing. Appointed lawyers in Warren cases work out of the Ninth Judicial District's Thief River Falls office, 208 LaBree Avenue, Suite 102, Thief River Falls, MN 56701, 218-681-0952. Some families choose to hire their own attorney, and that is fine too.

The jail offers video visits. You pay for them through InmateCanteen, the service the Sheriff names for families, at inmatecanteen.com. Make an account there, then add funds for video visits.

Visit times, in-person visits and the rules for visitors are set by jail staff. Call 218-745-5411 before you plan a trip to Warren. Ask which kind of photo ID they accept, and if kids are allowed along. Our visiting guide covers tips on dress and behavior that apply at most jails.

Money goes on a person's account, often called their "books," through InmateCanteen. The Sheriff points families to that site for deposits. Those dollars buy items from the jail store, such as chips, shampoo or writing paper.

Have their legal name handy before you pay. For fees, limits or other ways to pay, ask staff at 218-745-5411. Our deposit guide and our commissary guide explain how jail stores work. Never put cash in the mail.

Phones in the Warren jail make outgoing calls only. The jail does not take calls meant for a person held there. Here is how to stay in touch:

• Leave a voice message. Call 218-416-1140 and follow the prompts.
• Get calls from them. The phone company is Reliance Telephone. Fund the phone wallet of the person held through the Reliance page for this jail.
• Calls not getting through? Reach Reliance at 800-896-3201.

Remind them to keep details of the arrest for conversations with their lawyer. Our jail phone guide and messaging guide give more tips.

The jail's street address is 208 E Colvin Ave., Suite 1, Warren, MN 56762. Before you send a letter, photo or book, call jail staff at 218-745-5411. Ask three things:

1. The exact way to write the address, and whether a booking number goes on it.
2. Which items are allowed in the envelope, like pictures, greeting cards or printed sheets.
3. How books and magazines have to be sent.

Copy the name letter for letter from the roster, and add where you live in the upper left corner. Our jail mail guide lists common rules. Skip cash, postage stamps, stickers and glue.

Jail staff bag and store whatever the person carried in at booking. Ask staff when they are handed back. If you need to collect a phone, keys or a wallet for them, call 218-745-5411 first. Ask staff whether the person must first approve the pickup in writing. Then agree on a day to come by.

The Sheriff's Office is at 208 E Colvin Ave., Suite 1, Warren, MN 56762. The front desk is open Monday to Friday from 8:00 a.m. to 4:30 p.m. Bring a photo ID.

Keeping people in the jail safe and cared for is the Sheriff's job. Call jail staff right away at 218-745-5411 if the person needs a daily prescription, has a long-term illness or might hurt themselves. Give the drug name, the dose, the pharmacy and the doctor's name.

Also urge the person to tell jail staff about it from the inside. For a life-or-death problem, call 911. When you worry about their mental state, tell staff that plainly so they can act fast.

Worried about a warrant? Check by calling 218-745-5411. Give the deputy on the line a full name and birth date. On the state level, people who fled supervised release appear on the corrections department's Wanted Fugitives page. For court cases, which are a different thing from warrants, search Minnesota Court Records Online. Want a warrant gone? Get legal advice before anything else. Next, reach the court where the judge signed it and request a fresh hearing date, or surrender at the jail. Here that court is the District Court at 208 E Colvin Ave, Suite 18, Warren, MN 56762. Court administration answers at 218-745-4921.

Criminal cases from every part of the county are heard in District Court in Warren. It belongs to the state's Ninth Judicial District. Court administration is at 208 E Colvin Ave, Suite 18, Warren, MN 56762, 218-745-4921, open weekdays from 8:00 a.m. to 4:30 p.m.

• Look up dates for free with the state hearing search.
• The omnibus hearing, a review of the evidence, is usually set (Rule 11.01) within 42 days of the first appearance.
• Under Rule 11.09, trial must begin within 60 days once a speedy trial is demanded.
• Under Minn. Stat. 609.49, missing a hearing in a felony case is a crime by itself. Surrendering within 48 hours of the missed date wipes out that extra charge.

Our court guide explains every stage, from charge to sentence.

Minnesota has one federal court, the U.S. District Court for the District of Minnesota. Of its four courthouses, Fergus Falls is closest: 118 South Mill Street, Fergus Falls, MN 56537. The clerk's office answers at 612-664-5000.

1. Expect a detention hearing (18 U.S.C. 3142). At it, the federal judge chooses between letting them out and keeping them jailed until the case ends.
2. Before trial, the U.S. Marshals Service holds them. Call its Minnesota office, 300 South 4th Street, Suite 402, Minneapolis, MN 55415, 612-664-5900, to ask where.
3. Many federal prisoners in the state stay at the Sherburne County Jail, 13880 Business Center Drive NW, Suite 100, Elk River, MN 55330, 763-765-3500.
4. After sentencing, custody shifts to the federal Bureau of Prisons. Its online inmate locator lists where they are; search by register number or name.

Immigration holds follow a set order. This is how one usually plays out in Minnesota:

1. The jail gets an ICE detainer, which comes on Form I-247A.
2. Federal rules say a jail may keep the person up to 48 hours after they would otherwise be released, so ICE can pick them up (8 CFR 287.7(d)).
3. Minnesota's Attorney General weighed in through a formal opinion signed February 6, 2025. In that reading, Minnesota statutes give a county jail no basis to hold anyone who is due to go free, solely because ICE filed a detainer. A lawyer can explain what that means for one person.
4. ICE's St. Paul Field Office takes questions at 1 Federal Drive, Suite 1601, Fort Snelling, MN 55111, 612-843-8600.
5. If ICE has already picked them up, the ICE Online Detainee Locator can find them. Type in the A-number (alien number) when you know it. Lacking that, a full name plus birth country will do.

A felony prison term means the Minnesota Department of Corrections takes over. The person stays in Warren for now. Later, the Sheriff's Office delivers them to state intake. There, staff process and evaluate each new arrival.

• Search names on the DOC Offender Locator. Someone just received by the state may not appear for several business days.
• Read our guide to Minnesota state prisons for visits, mail and calls.
• For roughly the last third of the term, people usually live back home on supervised release, checked on by state agents.

State probation for this county is handled by the DOC field office at 141 Main Avenue South, Thief River Falls, MN 56701, 218-683-8520.

Minnesota counts anyone not yet 18 as a juvenile (Minn. Stat. 260B.007). Their case belongs in the juvenile part of the District Court. Under Minn. Stat. 260B.176, police usually send a youth home with a parent. Keeping them is meant for a teen who is a danger or who seems likely to skip court.

• The Warren jail's state license lets it keep a youth for up to 24 hours. Do not include weekend days or holidays when you tally it.
• A locked juvenile detention stay can pass the 36-hour mark only with a court petition plus a judge's go-ahead. Weekends and holidays are not counted.
• From age 14 on, a very serious charge can send a teen to adult court (certification) or into the extended jurisdiction juvenile (EJJ) track.

To learn where a youth is placed, call probation at 141 Main Avenue South, Thief River Falls, MN 56701, 218-683-8520. Court administration in Warren can also help at 208 E Colvin Ave, Suite 18, Warren, MN 56762, 218-745-4921.

The roster shows the agency that made each arrest. These are the agencies families are most likely to deal with:

• Sheriff's Office, 208 E Colvin Ave., Suite 1, Warren, MN 56762, 218-745-5411. The City of Warren says the Sheriff provides its police service 24 hours a day. The state Attorney General's list of police departments names none in this county, so deputies also answer calls in towns such as Stephen, Argyle, Newfolden, Middle River, Grygla, Oslo, Alvarado, Viking, Holt and Strandquist, and on rural roads.
• Minnesota State Patrol, headquarters at 445 Minnesota Street, Suite 130, St. Paul, MN 55101, 651-201-7100. Use the State Patrol's contact list to reach the district that patrols this area.

For any emergency, dial 911.
