Cooper County Detention Center Overview
Cooper County Detention Center is operated by the Cooper County Sheriff's Office. The county government listing places the sheriff and jail at the county courthouse complex in Boonville and gives separate public numbers for the sheriff's office and detention center. The sheriff's detention unit page identifies the facility as the county's jail for male and female detainees. That local role matters because the jail roster is meant for Cooper County jail custody, not every incarcerated person who has a Cooper County tie.
The official detention unit page names Captain Amanda M. Blank as jail administrator, lists a 70-bed capacity, and states that the current facility was constructed in 1999. The same sheriff source lists inmate fees as $50 per day plus medical costs. No official page located in the research published housing unit names, a separate booking desk schedule, or a current daily population count. For broad county custody context, the Cooper County jail inmate records page explains how the county roster connects to booking and court information.
Cooper County Jail Custody
The Cooper County Detention Center holds local detainees for the sheriff's office and other local arresting agencies. The research describes the population as male and female county detainees, including people waiting for court and local sentenced inmates. A person arrested in Cooper County may appear on the county roster while booking data, charges, bond, warrants, and holds are being entered into JailTracker. A person sentenced to Missouri Department of Corrections custody should be checked through the DOC Offender Search after transfer instead of through the county jail roster.
| Custody Type | Where to Search | What It Means |
|---|---|---|
| Recent Cooper County arrest | Sheriff Inmate Lookup or jail phone | Booking may be recent, and online timing is not published. |
| Pretrial county custody | JailTracker roster | The person is held while charges, bond, or court dates are pending. |
| Local sentence | JailTracker roster | The sentence is being served at the local jail when allowed by the court. |
| Sentenced DOC custody | Missouri DOC Offender Search | The person has moved into state corrections supervision or prison custody. |
Look Up Cooper County Detention Center Inmates
Current Cooper County Detention Center inmate lookup starts at the sheriff's official inmate lookup frame, which loads the Public Safety Cloud JailTracker roster. The roster app is scoped to Cooper County. It is a free public path, but the research found that the app can load as a browser application and may use CAPTCHA checks before full results are shown. If the frame fails, the direct JailTracker URL is the next online step.
- Open the sheriff's Inmate Lookup link from the Cooper County Sheriff's Office site.
- Use a last name first, then add a first name when the roster returns too many matches.
- Complete any CAPTCHA prompt and wait for the roster application to finish loading.
- Open the matching profile and compare name, booking data, charge, bond, hold, case, and facility fields.
- Call the Cooper County Detention Center when a very recent arrest, release, or hold does not appear online.
The roster app's captured field labels include Last Name, First Name, Search Type, Released Since, Agency, CAPTCHA, charge fields, case number, warrant number, bond amount, court fields, holds, and release date/time fields. Those labels show what the platform can support. They should still be read as roster fields that may depend on Cooper County's public configuration and the current custody record.
The Cooper County Sheriff's detention unit page shows the local jail facility, capacity, visitation rules, JailATM deposits, and CIDNET phone setup.
The screenshot source is useful because it ties the Cooper County Detention Center roster process to the same official sheriff page that publishes visitation, account, and phone details.
Cooper County Jail Contact
Use the detention center number for custody questions, jail information, and details that the roster does not show. The sheriff's main number is better for non-emergency records questions and sheriff's office business. The county government page lists public office hours as Monday through Friday, 8:00 a.m. to 4:00 p.m., and it warns that hours can vary. Emergency calls should go to 911, not the jail information line.

Cooper County Detention Center Visits
Cooper County Detention Center visits are handled by kiosk and are monitored by detention staff. The sheriff's official detention page states that each inmate gets one visit per visiting day, and each visit must be scheduled 24 hours in advance. Visits are limited to 30 minutes, but detention operations may shorten or cancel a visit. A visitor must provide positive identification, and anyone under 18 must be with an adult.
| Day | Hours | Who | Rules |
|---|---|---|---|
| Saturday | Noon-4:00 p.m. | Male and female inmates | One scheduled kiosk visit per inmate, 30-minute limit. |
| Sunday | Noon-4:00 p.m. | Male and female inmates | Same rules; operations may shorten or cancel visits. |
Some visitor limits are specific. Only one visitor may be in the visitation screen at a time. Co-defendants and anyone incarcerated in Cooper County Detention Center within the last 12 months cannot visit without prior written approval from the sheriff or designee. A person on probation or parole also needs prior authorization from the supervising officer before visiting.
Cooper County Jail Money and Phone
The sheriff's detention page documents two inmate service channels for the Cooper County jail. Deposits use JailATM, and the page states that only the inmate's name is needed to make a deposit. Phone accounts use CIDNET, either through the customer website or by phone. The research did not locate a Cooper County jail mail policy, so postcard rules, book rules, scanning rules, and package limits should be confirmed with the jail instead of assumed.
| Service | Provider or Channel | Detail |
|---|---|---|
| Inmate deposits | JailATM | Issue line listed by sheriff: 1-866-933-6386. Only inmate name needed. |
| Inmate phone account | CIDNET | Phone setup also available at 1-888-984-1903. |
| Inmate fees | Cooper County Detention Center | Sheriff page lists $50 per day plus medical costs. |
| Mail policy | Call the jail | No official Cooper County jail mail policy was located in the research. |
Cooper County Jail Records
JailTracker is the fastest public path for a current Cooper County Detention Center inmate record, but it is not the only access channel. The detention center phone is the fallback for a new booking, a recent release, or a custody status that is not clear online. Records that are not visible through the roster can be requested from the sheriff's office by phone, email, mail, or in person. The research did not find a Cooper-specific online Sunshine request form.
Missouri public access rules also affect jail records. RSMo 610.100 covers arrest and incident records, while Missouri Sunshine Law guidance explains open-records duties for public governmental bodies. A booking charge is not the same thing as a filed court charge. Cooper County Circuit Court and Case.net should be checked after the prosecutor files a case, especially when bond or charge status changes after first appearance.
Note: Confirm custody and visiting status with the detention center before traveling, since roster timing and operations can change quickly.
Cooper County Detention Center Context
Cooper County has a layered jail history in Boonville. The current detention center is the sheriff's modern local jail, built in 1999 according to the sheriff's detention page. It should not be confused with the Old Cooper County Jail and Hanging Barn, a historic Boonville site used from 1848 to 1979. Current custody, jail visits, deposits, and inmate lookup run through the Cooper County Detention Center and the sheriff's roster channels.
The county also has a state prison, Boonville Correctional Center, within Cooper County. That facility holds sentenced Missouri DOC male offenders and has a separate DOC locator, DOC visiting rules, and prison phone system. Once a person is sentenced and transferred into state custody, the county jail roster may no longer be the right place to search. The Boonville Correctional Center inmate lookup page covers that state-prison track.
