Maries County Inmate Population
The Maries County inmate population begins with one local detention facility: Maries County Jail / Maries County Sheriff's Office Detention Center at 211 4th Street in Vienna. The facility is operated by the Maries County Sheriff's Office, led by Sheriff Mark Morgan, and the sheriff's Jail Division describes its work as detention for people awaiting trial or serving court-ordered sentences. That local jail population is different from a Missouri Department of Corrections prison population, a federal Bureau of Prisons population, or an ICE detention population. No separate city jail, regional jail, Missouri state prison, BOP prison, or ICE detention center was found in Maries County through the official facility lists reviewed.
Because Maries County is rural and has a single county jail, a change of just a few people can move the local jail count a great deal. Arrests, first appearances, bond decisions, warrants, court-ordered sentences, medical or security holds, and transfers to state prison all affect the daily count. The sheriff site gives county context of 8,432 citizens, 527 square miles, and 10 deputies. U.S. Census QuickFacts lists a July 1, 2025 estimate of 8,397 residents, the 2020 Census count of 8,432, and the 2010 Census count of 9,176, with the same 527 square miles of land area.
The Maries County Sheriff's Office homepage shows the local custody and public-record modules used by residents, including roster, booking, release, warrants, forms, and Case.net links.
Those modules are useful starting points, but Maries County users still need phone, records-request, court, DOC, federal, and notification backups when an online jail module is unavailable.
Maries County Inmate Statistics
The current Maries County jail population was not published on the sheriff website during June 2026 research. The current rated capacity also was not published on the current sheriff site. The best numeric source found for jail population trends is the Vera Institute Incarceration Trends dataset, which provides historical county-level jail population, admissions, rate, and capacity fields derived from public correctional data sources. Those figures should be read as historical trend markers, not as a live roster count.
For a small jail, the difference between "current" and "historical" matters. Vera's historical rated capacity field lists 14 for Maries County in several historical rows, but the sheriff site did not republish that number as the present operating capacity. The sheriff roster, booking, and release modules were offline during research, so no live count could be confirmed from the local website. Census and sheriff population figures help put the jail data in scale, but they do not replace a current jail count from the custodian.
| Measure | Figure | Source / Year |
|---|---|---|
| Current local jail population | Not published | Sheriff roster, booking, and release modules offline, June 2026 |
| Current jail rated capacity | Not published on current sheriff site | Sheriff site research, June 2026 |
| Historical jail rated capacity | 14 | Vera county dataset historical capacity rows |
| Total jail population | 11 | Vera county dataset, 2018 |
| Total jail admissions | 47.75 | Vera county dataset, 2017 |
| Jail population rate | 207.27 per 100,000 residents age 15-64 | Vera county dataset, 2018 |
| County population | 8,397 | U.S. Census QuickFacts, 2025 estimate |
Maries County Jail Trends
The historical Maries County inmate population trend is low in raw numbers, but it is not flat. Vera reports a total jail population of 5 in 2005, 4 in 2006 and 2007, 6 in 2008 through 2010, 16 in 2012, 12 in 2014, 10 in 2015, 10.33 in 2016, 10.67 in 2017, and 11 in 2018. Admissions also shifted across the years with available data, including 80.25 in 2010, 75.25 in 2009, 65.25 in 2015, 46.25 in 2016, and 47.75 in 2017.
The 2012 figure is notable because it sits above the historical 14-bed capacity reference, but no current local overcrowding dashboard, construction plan, consent decree, or jail litigation source was located in the official materials reviewed. The safer reading is that Maries County has a small jail with sparse current public data. A single court week, warrant sweep, transfer delay, or sentence commitment could change the visible count if the roster returns online.

Maries County Inmate Makeup
Published demographic detail for the Maries County inmate population is limited. Vera reports sex breakdowns for several historical rows: 2018 shows 11 total, with 8 male and 3 female; 2017 shows 10.67 total, with 7.76 male and 2.91 female; 2016 shows 10.33 total, with 7.51 male and 2.82 female; and 2015 shows 10 total, with 8 male and 2 female. Race fields were blank in the extracted recent rows, so a race breakdown should not be inferred from the available material.
The 2005 Vera row is the one historical row with more detail in the research: 5 total, 5 male, 0 female, 5 white, 4 pretrial, and 1 sentenced. More recent Maries County sources did not publish a live demographic dashboard, felony or misdemeanor breakdown, average length of stay, or daily pretrial-sentenced split. The sheriff's Jail Division page gives the practical custody categories instead: people awaiting trial and people serving court-ordered sentences.
Definition box: Pretrial means a person is held before the case is resolved. Sentenced means a court has ordered jail or prison time. A detainer is a hold from another agency. DOC means Missouri Department of Corrections custody, which is separate from the Maries County jail roster.
Maries County Inmate Laws
Missouri law shapes both custody and public access. The Maries County Sheriff runs the jail, receives people lawfully committed to jail, and must follow state rules for release, medical care, and records. Missouri public-record statutes also explain why a basic arrest or incident record may be available in some cases while other records are closed, redacted, or withheld. The sheriff's own report request form lists active investigation, closed case or nolle dismissal, closed record, and arrest expungement as possible reasons a requested report may not be released.
Key Statutes:
RSMo 610.100 sets the framework for public access to arrest and incident records, subject to statutory limits.
RSMo 221.020 places custody, rule, keeping, and charge of county jails under the sheriff except as otherwise provided.
RSMo 221.040 requires sheriffs and jailers to receive people lawfully apprehended or committed to jail.
RSMo 221.120 addresses medical, dental, and medicine needs for county-jail prisoners when care is needed.
RSMo 221.510 requires a warrant check before a prisoner is released or transferred.
Other Missouri record statutes matter when someone seeks old booking, arrest, or photo records. RSMo 610.105 addresses closure after nolle prosequi, dismissal, or suspended sentence in listed circumstances. RSMo 610.120 says closed records are retained but not open to the general public except as allowed by law. RSMo 610.122 and 610.140 cover expungement paths for qualifying arrest and criminal records. RSMo 211.151 adds special closure and expungement rules for juvenile fingerprints and photos.
Maries County Prison Population
A person can be part of Maries County's criminal-justice flow without being in the Maries County Jail. Vera rows show total prison population figures for people from Maries County, including 29 in 2015, 41 in 2016, 36 in 2017, 34 in 2018, and 32 in 2019. Those figures describe people from the county in state prison, not a state prison located inside Maries County. Official MODOC facility lists did not show an adult state prison physically in Maries County.
Once a person is sentenced to Missouri prison and received by DOC, the county jail roster is no longer the right tool. MODOC Offender Web Search covers active offenders under Missouri Department of Corrections supervision, including probationers and parolees, and it searches names including aliases after a CAPTCHA step. It does not provide discharged-offender information and may suppress some records for safety, security, or confidentiality reasons. During research, the MODOC page showed offender data current as of 06/18/2026 09:00 PM.
The MODOC Offender Web Search screenshot shows the CAPTCHA gate that separates state prison and supervision lookups from the county jail roster.
That search belongs to the state-prison and supervision side, so it should not be used as proof that someone is or is not inside the Maries County Jail on a new arrest.
Search Maries County Inmates
The official Maries County inmate search starting point is the sheriff's inmate roster. During research in June 2026, that roster stated the module was offline for maintenance. The sheriff homepage also had Inmate Booking and Inmate Release modules, and both were offline during the same review. That does not mean no one is in custody. It means the online roster path was unavailable and users need the fallback chain.
Use the roster first because it is the official public-facing custody page when available. If it is still offline, call 573-422-3381, contact or visit the Sheriff's Office at 211 4th Street in Vienna, submit the report request form for records, then move to court, DOC, federal, or immigration systems based on the custody type. Avoid unofficial roster and mugshot aggregator sites as primary sources, especially when the official sheriff module is down.
- Open the official Maries County sheriff roster and check whether the module is live.
- If it remains offline, call 573-422-3381 and ask whether the person is housed locally, transferred, released, or held on another agency's matter.
- Use the sheriff's Report Request Form for report, booking-photo, or incident-record requests that are not available online.
- Search Missouri Case.net once charges, hearings, warrants, or dispositions may exist in court.
- Search MODOC for sentenced Missouri offenders, BOP for federal inmates, and ICE ODLS for immigration custody.
The official Maries County inmate roster was captured with a maintenance notice during research.
The offline notice is why the phone, form, Case.net, MODOC, MOVANS, BOP, and ICE paths are part of the Maries County lookup workflow.
Maries County Roster Lookup
The Maries County sheriff site has a public roster framework, but no live inmate profile could be opened during research because the roster, booking, and release modules were offline. The homepage disclaimer says roster information is collected from public sources, is maintained for the convenience of site visitors, and cannot be certified for accuracy or authenticity by the Sheriff's Office or Detention Center. That warning matters even after the module returns online because a jail roster is a custody aid, not a certified court judgment.
| Field or Control | Type | Required | Notes |
|---|---|---|---|
| Inmate Roster | Module/page | Unspecified | Official page exists, but the module was offline for maintenance |
| Inmate Booking | Homepage module | Unspecified | Offline during research, no public fields visible |
| Inmate Release | Homepage module | Unspecified | Offline during research, no public fields visible |
| Accept / Cancel | Disclaimer interaction | Optional interaction | Shown on homepage modules before roster-style content |
When a person is not found online, allow for booking intake, court transport, release, transfer, or module downtime. For bond questions, ask the jail whether bond has been set, whether other holds exist, and whether payment information can be released. Do not assume that a listed or rumored bond will release the person, because Missouri law requires a warrant check before release or transfer.
Maries County Records Requests
The strongest local fallback for past or released inmate records is the sheriff's Report Request Form. It asks for the requester's name, address, phone, incident date, location of incident, type of report, involved parties, reason for request, delivery choice, email confirmation, and signature. Delivery choices are emailed, mailed, or pickup in office. The form states that the Sheriff's Office will act within 3 business days after the request date.
Fees are specific and should not be mixed with bond rules. The form lists $10 per report, $0.10 per page for reports longer than 2 pages, and $5 per photo requested with the report. Fees must be paid in advance, and extensive searches may add fees. Official-use checkboxes on the form also show local reasons a report may not currently be released, including active investigation, closed case or nolle dismissal under 610.105, closed record under 610.120, and arrest expunged under 610.122.
Maries County Jail Vs Prison
County jail, state prison, federal custody, and immigration detention are separate systems. Maries County Jail holds people awaiting trial and people serving court-ordered sentences at the county level. Missouri DOC handles sentenced state prisoners and people under state supervision. BOP handles federal inmates. ICE ODLS is for people in ICE custody or CBP custody for more than 48 hours. MOVANS/VINELink is a notification system, not a complete roster.
| Custody Type | Who It Covers | Where to Look |
|---|---|---|
| Maries County jail | Local pretrial detainees and county-level court-ordered sentences | Official roster if live, then 573-422-3381 and sheriff records form |
| Missouri DOC | Sentenced state prisoners, probationers, and parolees under MODOC supervision | MODOC Offender Web Search |
| Federal BOP | Federal inmates from 1982 to present | BOP Inmate Locator |
| ICE detention | ICE custody or CBP custody for more than 48 hours | ICE Online Detainee Locator System |
| MOVANS/VINELink | Custody and court notifications for jail or DOC changes | Missouri MOVANS / VINELink |
The Missouri MOVANS page explains custody and court-event notifications for county jail and DOC custody.
Use notifications to monitor changes after a record is found, not as a substitute for direct jail confirmation or the correct custody locator.
Maries County Detention Facility
The Maries County detention facility list has one item. The Maries County Jail / Maries County Sheriff's Office Detention Center is the local jail for people awaiting trial or serving court-ordered sentences. No separate city jail, regional jail, Missouri DOC prison, BOP prison, or ICE detention center was found in Maries County. If Belle police or another agency makes an arrest in the county, the practical custody path still points to the sheriff, the jail, and then Case.net once a public court case exists.
- Maries County Jail / Maries County Sheriff's Office Detention Center - county jail operated by the Maries County Sheriff's Office at 211 4th Street in Vienna for local pretrial and court-ordered sentence custody.
Maries County Inmate FAQ
How big is the Maries County inmate population?
The current Maries County jail population was not published during June 2026 research. Historical Vera data lists a jail population figure of 11 in 2018, 10.67 in 2017, 10.33 in 2016, and 10 in 2015. Treat those as historical trend figures, not a live count.
What is the jail capacity?
The current sheriff site did not publish a current rated capacity. Vera historical county rows list a Maries County jail rated capacity of 14 in multiple historical capacity rows. Because the local sheriff site does not state that number as current, it should be labeled as historical.
How do I search Maries County inmates?
Start with the official sheriff roster. If it is still offline, call 573-422-3381, use the Report Request Form when a record request is needed, and search Case.net for public court cases. Use MODOC, BOP, or ICE only when the person belongs to those custody systems.
Does Maries County have more than one jail?
No separate city jail, regional jail, state prison, federal prison, or ICE detention center was found in Maries County. The local detention facility is Maries County Jail / Maries County Sheriff's Office Detention Center in Vienna.
Can I look up a released inmate?
The sheriff roster and release modules were offline during research, and no public archive retention period was published. For past records, use the sheriff's report request form and provide the person's name, incident or booking date if known, involved parties, and delivery choice.
Where do state prisoners from Maries County appear?
Sentenced people under Missouri DOC supervision appear in MODOC Offender Web Search when the record is public and active. They are no longer tracked as current county jail inmates after transfer to DOC custody.
