Osage County Detention Center Overview
The Osage County Sheriff's Office operates the Osage County Detention Center from the courthouse complex in Linn. The sheriff's Detention Division description says staff work with Patrol by booking people brought in pending charges or warrants, providing basic needs, ensuring court appearances, and releasing people when the judicial system grants release. Those facts place the facility in the county-jail category. It is not a state prison, federal facility, or immigration detention center.
The facility is tied closely to the courthouse. The county homepage states that the courthouse at 106 E. Main Street houses the Sheriff/Jail, Prosecuting Attorney, and Circuit Clerk. That local setup matters because a person searching custody may need the jail for current status, the Circuit Clerk or Case.net for filed charges, and the Prosecuting Attorney for victim-witness or prosecution information. The same building address does not mean the same office controls every record.
Osage County Detention Center Population
Current rated capacity was not published in the official county sources inspected. The only concrete jail population number found in the research file was historical: the Prison Gerrymandering Project table, using Bureau of Justice Statistics jail census data, lists Osage County Jail with an average daily population of 12 for 2013. That is not a current bed count. It is a historical reference point for a small rural jail.
KRCG reported in July 2025 that the jail had been empty since mid-May 2025 and was reopening after a two-month closure related to staffing and upgrades. That recent report is useful as an operations caveat. It should not be treated as a current population figure, but it explains why phone verification is especially important for immediate custody questions.
Who Is Held at This Jail
Osage County Detention Center holds people booked by Osage County deputies and local agencies pending charges or warrants, people waiting for court appearances, and people who stay in local custody until the court authorizes release. A person may also be held because another warrant, probation or parole hold, DOC transfer, federal hold, or ICE detainer blocks release.
- Recent Osage County arrests awaiting booking, bond, or first appearance.
- Warrant arrests tied to Osage County or another jurisdiction.
- People waiting for transportation or court appearance in the 20th Judicial Circuit.
- Short local sentences when ordered by the court.
- Holds that may require state, federal, or immigration follow-up.
Find Osage County Detainees
No official online live inmate roster was located for Osage County Detention Center. The correct lookup path starts with the jail phone. The sheriff site publishes the jail phone and detention information, while the Osage County Circuit Clerk points court users to Case.net for case status once charges are filed. MOVANS can help with custody and court notifications, and MODOC applies after a person moves to state custody.
- Call Osage County Detention Center at 573-897-5750 with the person's full legal name, age or date of birth, arrest date, and arresting agency if known.
- Ask whether the person is held at the jail, transferred, released, or held on another agency's warrant or detainer.
- If jail staff cannot release the requested detail by phone, ask how to submit a written Sunshine request to the sheriff.
- Search Missouri Case.net for formal charges, hearing dates, warrants, docket entries, and dispositions after a public case is filed.
- Use the MODOC Offender Web Search, BOP locator, or ICE locator only when the custody type is no longer local county jail custody.
Osage County Jail Address
The jail, sheriff, prosecutor, and circuit clerk are all associated with the courthouse address in Linn, but the jail line is the right first contact for current custody. For written sheriff records requests, use the sheriff's office mailing address and be specific about the record type sought.

Visiting Osage County Detainees
The official sheriff website inspected did not publish a full in-person visitation schedule, visitor application, dress code, child visitor rule, ID rule, or on-site/remote visit price table. Do not rely on a guessed schedule. Call the jail before visiting or before scheduling a video visit through Cidnet. The sheriff site does state that Cidnet supports voice, video, mail apps, and texting.
| Visit Type | Schedule | How to Schedule | Notes |
|---|---|---|---|
| In-person jail visit | Not published in official Osage source | Call 573-897-5750 | Confirm ID, dress, visitor count, and arrival rules before travel. |
| Video visit via Cidnet | Not published in official Osage source | Use Cidnet setup or call jail | Cidnet data rate listed by sheriff site is $0.30 per 1 MB. |
| Attorney call or visit | Not published | Attorney should notify facility | Attorney calls are not recorded when the private number is configured. |
Note: Verify custody and visitation with the jail before traveling, especially when recent staffing or transfer issues may affect operations.
Mail, Phone, and Money
The sheriff site identifies Cidnet as the jail communication provider for voice, video, and mail apps, and says jail texting is available. The site also says attorney calls are not recorded, private attorney numbers should be provided to the facility, and each inmate automatically has the Public Defender's Office set to do-not-record. Those details are more specific than a generic jail-phone statement and should be used when families or attorneys need to set up communication.
| Service | Provider or Detail | Research Notes |
|---|---|---|
| Voice, video, mail apps, texting | Cidnet | Data sold at $0.30 per 1 MB according to sheriff site. |
| Attorney calls | Facility-configured private numbers | Not recorded when set up; Public Defender is automatically do-not-record. |
| Physical mail | No full policy located | Call before sending books, packages, photos, or money. |

The image supports the local sheriff source for communication and commissary details, but custody still must be confirmed through the jail line.
Osage County Commissary Deposits
Incarcerated people at the Osage County Detention Center have commissary access for items such as e-cigs and phone cards. The sheriff page says money or money orders can be dropped off at the Detention Center at any time, and credit or debit deposits can be made in person or by phone. The official deposit instruction sheet says the credit/debit POS machine is in the sally port area and that a detention officer can assist.
| Method | Where or How | Fees and Limits |
|---|---|---|
| Cash or money order | Drop off at Detention Center; verify inmate identity first | No checks allowed. |
| Credit/debit in person | POS machine in the sally port area | Processing fees apply and vary by deposit amount. |
| Credit/debit by phone | Call 573-897-5750 and provide caller/card details to detention officer | Card information is destroyed promptly after transaction per instruction sheet. |
Booking and Court Appearance
The Osage County booking path begins with an arrest or warrant service by a deputy, local officer, Missouri State Highway Patrol, or another agency. Jail staff confirm identity, record the arresting agency, collect property, conduct required searches, begin a booking record, and coordinate custody status. A booking photo and fingerprints may be part of intake, but no official public county mugshot roster was found.
After booking, the court path can move quickly or slowly depending on the case. The jail can answer immediate custody and release conditions when releasable. Case.net becomes useful after a public court case is filed. The Circuit Clerk can help route public case-status and copy questions, while the prosecutor reviews reports and decides what charges to file or decline. A jail charge label is not the same as a final court disposition.
Records and Mugshots
For records not posted online, submit a specific Missouri Sunshine Law request to the sheriff. Ask for the arrest report, booking record, jail log, or booking photograph rather than using vague wording. Include the subject's full name, arrest date, arresting agency, report or case number if known, requester contact information, and preferred delivery method. Missouri law generally makes arrest and incident reports public, while allowing closure or redaction for active investigations, protected people, juvenile information, confidential material, and safety-sensitive details.
For booking photos, use the records request path. Case.net generally does not publish county jail booking photos. MODOC photos, when available after sentence or transfer, are prison/offender records rather than Osage County jail mugshots. Federal and ICE locators are custody tools, not public county mugshot galleries.
Directions and Arrival Notes
Use 106 E. Main Street, Linn, MO 65051 for the jail and courthouse complex. From the west or Jefferson City side, use U.S. 50 east toward Linn and follow local routing to Main Street. From the east, use U.S. 50 west toward Linn. Rural drive times can change with weather, farm equipment, school traffic, and courthouse events, so confirm timing before leaving.
The sheriff page says cell phones, cameras, and recording or transmission devices are not allowed in the Osage County Courtroom unless a judge has given prior approval and paperwork can be shown. The sheriff clarifies that this rule applies to the courtroom, not the entire courthouse. Jail-specific visitor ID, locker, dress, and wait-time rules should still be confirmed by phone.
