The Cooper County Inmate Population
The Cooper County inmate population has two layers that should not be mixed. The Cooper County Sheriff's detention unit page describes the Cooper County Detention Center as the local jail for male and female detainees. That is the first place to check for a person arrested by a county or local law enforcement agency. The separate Boonville Correctional Center is a Missouri Department of Corrections prison in the same county. It holds sentenced state offenders and is searched through the state system, not the county jail roster.
Counts rise and fall for different reasons in each system. Local jail population changes with arrests, bond decisions, holds, short local sentences, and release orders. State prison population changes after sentencing and transfer to DOC custody. Cooper County's jail data is therefore about current detention and booking status, while Boonville Correctional Center is part of the statewide prison population physically located in Cooper County.
Cooper County Inmate Population Statistics
The researched figures are limited but useful. The sheriff's detention page publishes the current local jail capacity and the fact that the jail holds both male and female detainees. Prisoners of the Census, using Bureau of Justice Statistics data, lists an average daily population for the Cooper County Detention Center in 2013. The same source lists a state facility population for the Boonville institution in 2012. Those older figures should not be read as today's count, but they show the scale difference between the county jail and the state prison in Cooper County.
| Measure | Figure | Source / Year |
|---|---|---|
| Cooper County Detention Center rated capacity | 70 beds | Cooper County Sheriff's detention page, inspected June 2026 |
| Sexes held at county jail | Male and female | Cooper County Sheriff's detention page |
| Cooper County Detention Center ADP | 33 | BJS Census of Jail Facilities via Prisoners of the Census, 2013 |
| Cooper County 2024 population estimate | 17,122 | U.S. Census Bureau QuickFacts, July 1, 2024 estimate |
| Boonville state facility population | 1,244 | BJS state and federal adult correctional facilities data, June 30, 2012 |
Cooper County Inmate Population Trends
Cooper County does not publish a current online jail population dashboard in the research set. That matters because a public roster can show people in custody without providing a clean aggregate daily count. The best trend statement is narrow: the published county jail capacity is still 70 beds, while the only sourced historic average daily population located for the county jail is 33 in 2013. No official source in the project file supports a claim that the jail is currently under capacity or over capacity.
| Year | Jail ADP / Population | Notes |
|---|---|---|
| 2013 | 33 ADP | Cooper County Detention Center, BJS Census of Jail Facilities via Prisoners of the Census |
| 2024 | Not published in local source | Research found capacity, but no official county ADP dashboard or annual report |
| 2026 inspection | 70-bed capacity | Capacity still appears on the sheriff's detention unit page |
Note: A roster count from one day is not the same as an audited average daily population.
Cooper County Jail Capacity
The county detention center's published capacity is 70 beds. The same official page says the current facility was constructed in 1999 and holds both male and female detainees. No official Cooper County jail overcrowding notice, consent decree, new jail plan, or current average daily population report was located in the research. The 2013 average daily population of 33 was below the current published capacity, but the years do not match. It would be inaccurate to turn that older figure into a current utilization rate.
The Cooper County government sheriff page lists Sheriff Chris Class, the sheriff's office address, office hours, and detention center phone. The screenshot below comes from that official county government listing and is useful because it gives the local office path for custody questions when the public roster is unclear.
That county government page is the local starting point for office hours and phone contacts, while the sheriff's separate detention page carries the jail capacity, visitation, and inmate account details.
Laws Behind Cooper County Inmate Records
Missouri law treats many jail and arrest records as public records, but access is not unlimited. The most useful rule for Cooper County jail data is the distinction between arrest reports, incident reports, investigative records, court records, and DOC records. A public arrest report may confirm basic facts about an arrest, while a court file shows what the prosecutor filed. DOC records follow a separate statute once the person is in state custody.
Key Statutes:
RSMo 610.100 covers arrest and incident records, subject to closure rules and exceptions.
RSMo 221.020 places custody, rule, keeping, and charge of county jails and prisoners with the sheriff unless another statute applies.
RSMo 217.075 makes Missouri DOC offender records public records under Chapter 610, with confidential categories excluded.
Missouri DPS death-in-custody reporting explains state collection and reporting duties for deaths in custody.
Cooper County Jail and Prison Split
Cooper County has one local detention center and one state prison in the facility map. The Cooper County Detention Center is operated by the sheriff and handles recent arrests, pretrial detention, local sentences, bond questions, visits, inmate deposits, and jail phone accounts. Boonville Correctional Center is operated by the Missouri Department of Corrections and handles sentenced DOC offenders. A person can be physically in Cooper County and still not be a Cooper County jail inmate.
| Custody Type | Facility or System | Lookup Channel |
|---|---|---|
| Recent arrest or pretrial county custody | Cooper County Detention Center | Sheriff Inmate Lookup / JailTracker |
| Sentenced Missouri DOC custody | Boonville Correctional Center or another DOC facility | Missouri DOC Offender Search |
| Federal sentence | Federal BOP facility, not a Cooper County jail page | Federal Bureau of Prisons inmate locator |
| Immigration custody | ICE detention system | ICE Online Detainee Locator System |
How to Search Cooper County Inmates
The official Cooper County inmate lookup path starts at the sheriff's site. Its Inmate Lookup link opens a sheriff frame page that loads the Public Safety Cloud JailTracker roster for Cooper County. Because the roster is a live app, the static HTML does not expose every current person in custody. The app may also ask for CAPTCHA verification before it shows complete results.
- Open the Cooper County Sheriff's inmate lookup frame.
- If the frame does not load, open the Public Safety Cloud JailTracker roster URL from that official path.
- Search by last name, then add a first name if the app provides that field.
- Complete CAPTCHA if prompted and open the matching record.
- If the person is not listed after a recent arrest, call the Cooper County Detention Center at 660-882-6985.
The official Cooper County inmate lookup frame is shown below. It demonstrates that the sheriff sends users to JailTracker for current jail roster searches.
The frame confirms the county source, while the live roster app handles the current inmate records behind it.
Current Cooper County Roster Search
Research of the JailTracker app found a roster search model with name fields, a search type field, a released-since value, agency scoping, and CAPTCHA components. Those fields should be read as app configuration, not a promise that every option is visible to every user at all times. The public path appears free because the sheriff links directly to it and no fee notice was found for the roster search.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Last Name | Text | Unspecified | Main name search field in the app strings |
| First Name | Text | Unspecified | Useful for narrowing common names |
| Search Type | Option | Unspecified | Configuration exists, but visible options were not captured in static HTML |
| Released Since | Option or date-style value | Unspecified | Do not assume a release window unless the live app confirms it |
| CAPTCHA | Image/text verification | Conditional | The app contains CAPTCHA image and validation components |
What Cooper County Inmate Records Show
A Cooper County JailTracker record may include booking identifiers, charges, bond information, court fields, warrants, holds, release data, and an offender image field when the county configuration displays it. Because a live sample profile was not captured in static research, the safest phrasing is that the system is configured with these fields and may show them when enabled for a public record.
| Field | What It Shows |
|---|---|
| Name and aliases | First, middle, last name, or search name tied to the jail record |
| Booking or arrest identifiers | Arrest number, jacket number, control number, or similar jail-management ID |
| Booking and arrest dates | Original booking date, arrest date, or final release date if released data is shown |
| Charges and status | Charge description, crime level, charge status, counts, or sentence fields |
| Bond and holds | Bond amount, bond type, hold type, hold date, hold reason, or warrant number |
| Court fields | Case number, court name, court type, court date, or court time when enabled |
Past Cooper County Inmate Records
The sheriff's research did not publish a roster refresh rate or a clear rule for how long released people remain visible. If a person has already been released, start with the current roster, then use the sheriff's office records channel for booking records or arrest reports not online. Missouri's Sunshine Law process is the fallback for records that are not in the public app, and the request should name the record type as clearly as possible: booking record, arrest report, incident report, jail record, or booking photo.
Case records follow a different path. The Cooper County Circuit Court page directs users to Missouri Courts for case information, and the sheriff's links page also lists Case.net. A jail booking charge can appear before the prosecutor files the formal court charge, so a very new arrest may show in the roster before it appears in the court system.
State and Federal Inmate Lookup
The Missouri DOC Offender Search covers active offenders supervised by DOC, including probationers and parolees. The research page showed offender data current as of June 18, 2026, at 9:00 p.m. when inspected. It does not provide discharged-offender information and may omit some data for safety, security, or confidentiality reasons.
The Federal Bureau of Prisons inmate locator is for federal custody, and the ICE Online Detainee Locator System is for immigration custody. Neither is a Cooper County jail roster. VINELink is also available for custody notifications and is linked from the sheriff's official links page as "Vine Link (Inmate Status)."
The Missouri DOC offender search page is shown below. It is the correct search tool after a Cooper County case has led to DOC supervision or state prison placement.
Use the DOC locator for sentenced state custody, then return to the county roster only for Cooper County jail custody.
Cooper County Detention Facilities
The facility map has two entries because both serve inmate-population searches, but for different users. The primary county jail serves current local custody. The state prison is physically in Cooper County but belongs to the Missouri DOC system.
- Cooper County Detention Center is the 70-bed local jail operated by the Cooper County Sheriff's Office for pretrial detainees, local sentenced inmates, visitation, deposits, and jail phone accounts.
- Boonville Correctional Center is a minimum-security Missouri DOC prison for sentenced state offenders and uses the statewide DOC locator.
Cooper County Custody Terms
Jail records use short terms that affect how a search result should be read. A few definitions help separate a booking record from a court case or prison record.
- Booking
- Jail intake after arrest, including property inventory, identifiers, charges, and possible booking image creation.
- Bond
- A court-set release condition. Cash, surety, recognizance, and no-bond holds have different effects.
- Hold or detainer
- A legal or agency request that can keep a person in custody even when another charge has a bond amount.
- DOC custody
- State supervision or prison custody under the Missouri Department of Corrections, searched outside the county roster.
Cooper County Inmate Population FAQ
How big is the Cooper County inmate population? The county jail's only sourced historic ADP in the research is 33 for 2013, and the current published jail capacity is 70 beds. The state facility in Boonville had a much larger historic population figure, but that is DOC custody, not the county jail count.
How do I search the Cooper County inmate population? Search recent local custody through the sheriff's Inmate Lookup and JailTracker path. If the person has been sentenced to DOC, use Missouri DOC Offender Search instead.
Do Cooper County jail mugshots always appear online? The JailTracker platform has offender-image fields, but research did not confirm that Cooper County displays every booking photo publicly. Open the roster entry or request the record through the sheriff's office.
Where do court charges appear after arrest? Filed charges appear through Missouri Case.net and the Cooper County Circuit Court record path after the prosecutor files them. The jail roster may show an arrest charge before the court case is available.
