The Grundy County Inmate Population
The Grundy County inmate population is centered on the Grundy County Jail / Grundy County Law Enforcement Center, the sheriff-operated local jail in Trenton. The jail holds adult pretrial detainees, local sentenced misdemeanants, people awaiting court, and short-term holds for local law enforcement. Missouri law places the custody, rule, keeping, and charge of county jails and prisoners with the sheriff under RSMo 221.020, subject to the limited exceptions listed in the statute.
Population figures for Grundy County require caution. The county pages reviewed did not publish a current daily jail count, live roster, housing-unit count, or 2026 capacity dashboard. The most complete public county jail data in the research comes from the Vera Institute incarceration trends files, where the latest Grundy County jail population row is 2019. Those figures are useful for capacity, trend, and historical context, but they are not a current custody count for 2026.
The official county home page shows the law enforcement center as a local government building, and the sheriff page gives the sheriff's public phone channel. The Grundy County official home page also shows the downtown county setting that links the jail, the old jail/prosecutor office, and the courthouse block.
The local geography matters because most jail, prosecutor, and court questions move through downtown Trenton rather than through a separate state prison campus.
Grundy County Inmate Population Statistics
Vera's county incarceration trends file reports a 2019 rated jail capacity of 30 and a 2019 total jail population of 20 for Grundy County, Missouri. The same row reports 96 jail admissions, a jail population rate of 350.75 per 100,000 residents age 15 to 64, total incarceration of 61, and a total incarceration rate of 1,069.8 per 100,000 residents age 15 to 64. Because Vera's latest county jail row is 2019, each figure below should be read as a historical data point, not a present-day jail roster count.
| Measure | Figure | Source / Year |
|---|---|---|
| Rated jail capacity | 30 | Vera county incarceration trends, Grundy County, 2019 |
| Total jail population | 20 | Vera county incarceration trends, 2019 |

Vera also reports demographic fields for the 2019 Grundy County jail row, but those subtotals should not be converted into firm percentages. The research notes that some demographic subtotals do not sum cleanly to the total jail population, likely because jail survey data can include missing, unknown, or derived categories.
Grundy County Inmate Population Trends
The 2014 through 2019 Vera trend line shows the Grundy County inmate population below the 30-bed rated capacity in every listed year. The total jail population moved from 26 in 2014 to 20 in 2019, with a small rise and fall in the middle of the period. That does not prove the jail is never full on a given day, since jail counts move with arrests, bond decisions, court transports, releases, and transfers. It does show that the annual Vera figures did not identify an overcrowding pattern during the available window.
| Year | Total Jail Population | Rated Capacity | Notes |
|---|---|---|---|
| 2019 | 20 | 30 | Below rated capacity; 16 sentenced custody, 4 pretrial custody. |
| 2018 | 24 | 30 | Below rated capacity; 21 male and 3 female reported. |
| 2017 | 22 | 30 | 14.67 sentenced custody and 7.33 pretrial custody. |
| 2016 | 22 | 30 | Similar total population to 2017. |
| 2015 | 25 | 30 | Highest of this five-year window. |
| 2014 | 26 | 30 | Highest listed in 2014-2019 window. |
A January 2026 KTTN jail activity report is better read as an operations snapshot than as a population census. It reported six inmates booked during Jan. 12-18, seven inmates transported to associate circuit court Jan. 13, eight transported to circuit court Jan. 15, and thirteen releases, including four releases on DOC supervision. Those weekly events show movement through the jail and courts, not an average daily population.
Grundy County Jail Capacity
Capacity sources do not line up perfectly because they measure different points in time. Vera's jail construction file identifies a passed 2008 new jail project for Grundy County at $5,000,000, increasing capacity from 16 to 28. Vera's later county jail file reports 30 rated beds for each year from 2014 through 2019. The research did not locate a county-published current bed count, housing-unit plan, accreditation status, consent decree, jail release order, or active capacity emergency.
For the Grundy County inmate population, the safest public statement is that the best historical source shows the jail below rated capacity in the 2014-2019 trend window, while the live number must be confirmed with the sheriff's office. Staffing can still affect operations even when the jail is below its rated capacity. A September 2025 local report said Sheriff Rodney Herring discussed deputy shortage and pay issues with the county commission, but that report did not document a jail conditions lawsuit or a state finding.
Grundy County Inmate Population Laws
Missouri law controls who keeps jail custody, which arrest records are open, how public-record requests are handled, and when some records may close or be expunged. These laws do not create a county web roster by themselves. They do explain why the sheriff, court clerk, MODOC, and DPS each hold a different piece of the Grundy County inmate population record.
Key Statutes and Data Rules:
RSMo 221.020 places custody and charge of county jails and prisoners with the sheriff, except for specific statutory exceptions.
RSMo 610.023 requires public bodies to appoint a custodian and act on public-record requests as soon as possible, with a third-business-day response rule unless reasonable cause requires more time.
RSMo 610.100 defines arrest and incident reports and makes those reports open records, subject to closures and redactions listed in the statute.
RSMo 544.170 addresses warrantless arrest handling and the timing for release or complaint when a person is detained without a warrant.
RSMo 610.140 allows eligible people to petition for expungement of certain Missouri arrest, plea, trial, and conviction records.
The Missouri DPS Death in Custody Reporting Act page adds a statewide reporting layer. DPS says Missouri must collect and report deaths in custody to the U.S. Department of Justice quarterly, and agencies experiencing a death in custody are asked to submit the data template promptly. MODOC also publishes Sunshine Law offender data for state supervision records, which is separate from the county jail count.
Grundy County and State Prison
The Grundy County inmate population does not include a state prison physically located inside the county. The Missouri Department of Corrections adult-institution address list identifies nearby northern Missouri facilities, including Chillicothe Correctional Center in Livingston County and Crossroads Correctional Center in DeKalb County, but no adult DOC prison in Grundy County. When a person is sentenced to state custody, that person leaves the county jail count and moves into Missouri Department of Corrections systems.
The MODOC Offender Web Search is the main active-offender lookup for people in prison, on parole, or on probation under department supervision. It requires a captcha before search and, at inspection, showed data current as of 06/18/2026 09:00 PM. The MODOC web search does not provide information on discharged offenders and may exclude records for safety, security, or confidentiality reasons.
The MODOC Sunshine Law offender data page is a stronger historical state source because it describes downloadable nightly offender files with active and historical supervision data going back as early as 1974. These files include DOC number, name fields, assigned place, sentence county, release dates, sentence length, and charge-level records.
Search Grundy County Inmate Records
No official Grundy County Sheriff's Office web roster, current-inmate table, booking report, jail roster search page, or mugshot gallery was located on the county website during research. That changes the lookup order. A current Grundy County inmate search should begin with the jail phone line or an in-person contact, then move to state and court systems only when the case facts support it.
- Call the Grundy County Sheriff's Office at 660-359-2828 and ask whether the person is currently in custody, whether bond has been set, and whether a court date is available.
- If visiting in person, use the jail and law-enforcement center area at 115 E. 8th Street, Trenton, MO 64683, but confirm the entrance and lobby process by phone first.
- Check the official Grundy County Sheriff's Office app only for features that are visible and current. The app exists, but app-only roster and warrant tools were not verified in the research.
- Use the Missouri State Highway Patrol arrest reports only for Highway Patrol arrests, and remember that those reports remain online for five days.
- Search Missouri Case.net after charges are filed, because a court case can show charges, hearings, bond entries, warrants, and dispositions.
- Use MOVANS/VINELink for local jail, court-event, and DOC notifications where the system has a matching record.
- Use MODOC, BOP, ICE, or U.S. Marshals channels when the person is in state, federal, immigration, or federal pretrial custody instead of the county jail.
For a deeper county-only custody workflow, the Grundy County jail inmate records page separates current jail checks, released-inmate records, and state or federal lookup paths.
Grundy County Lookup Channels
Because the county did not publish an official web roster, the most useful field table is the one for substitute official portals. MSHP helps only when the arrest was made by the Highway Patrol. MODOC helps after sentencing or for probation and parole supervision. Case.net helps after the prosecutor files and the court opens a case. A Sunshine Law request helps when current public tools do not answer the record question.
| Channel | Search Fields or Inputs | Best Use | Limit |
|---|---|---|---|
| Jail phone | Name, date of birth if requested, custody question | Current local custody and release status | No web result or profile view |
| MSHP arrest reports | First name, last name, arrest county, troop, city/state, arrest date | Recent Highway Patrol arrests | Only MSHP arrests, five-day online window |
| Missouri Case.net | Litigant name, case number, county, filing date or hearing filters | Charges and court events after filing | Not a booking roster |
| MODOC Offender Web Search | Captcha, first name, last name, aliases | Active DOC prison, parole, and probation supervision | No discharged offenders |
| Sunshine Law request | Person name, date range, record type, agency | Arrest, incident, booking, or historical records | Redactions and closures may apply |
The MSHP arrest report page is one of the official substitute screens for recent arrest checks when the arresting agency was the Highway Patrol.
That search is narrow by design. It should not be treated as a complete Grundy County jail roster or a full local booking history.
Grundy County Inmate Record Details
No official public Grundy County jail profile could be inspected, so visible roster fields such as mugshot, housing unit, booking number, bond table, or charge statute should not be claimed as county web fields. Under Missouri's arrest-report law, an open arrest report at least concerns the arrest, detention or confinement incident, and charge. A requested booking record may include more, but the exact fields depend on what the sheriff's office maintains and what can be released under Missouri law.
| Record Type | What It May Show |
|---|---|
| Open arrest report | Arrest, detention or confinement incident, and charge when the report qualifies as open under RSMo 610.100. |
| Booking record request | Booking date and time, arresting agency, offense, bond, release status, and custody notes if maintained and releasable. |
| MSHP result | Arrest name, age, person city/state, arrest date, arrest time, arrest county, troop, and detail link when available. |
| Case.net case | Case number, filed date, party name, charges, docket entries, bond settings, hearing dates, warrants, dispositions, and sentencing entries. |
| MODOC offender data | DOC number, name, assigned place, sentence county, release dates, sentence length, and charge-level records. |
Grundy County Jail vs Prison
A county jail search and a state prison search answer different questions. The Grundy County Jail covers local custody before trial, short local sentences, court transports, holds, and transfers. MODOC covers sentenced state prisoners and people under state supervision. Federal and immigration custody are separate again, even when a person has a Grundy County connection.
| Custody Type | Who Is Covered | Where to Look | Common Confusion |
|---|---|---|---|
| County jail | Pretrial detainees, local sentenced misdemeanants, short-term holds | Grundy County Sheriff's Office, phone 660-359-2828 | A person may be booked locally before a court case is visible. |
| State DOC | Sentenced state prisoners, probationers, parolees | MODOC Offender Web Search and Sunshine offender data | A jail release can be a transfer to DOC, not street release. |
| Federal custody | Federal pretrial detainees and sentenced federal inmates | U.S. Marshals for pretrial custody, BOP locator after federal sentencing | Federal detainees may be housed in local partner jails. |
| Immigration detention | Adults in ICE custody or some CBP custody after 48 hours | ICE Online Detainee Locator System | ICE locators do not operate as county mugshot galleries. |
MOVANS and Grundy County Custody
MOVANS and VINELink are notification tools, not a replacement for the sheriff's custody desk. Missouri DPS says users can register for local jail or detention center custody, court events, and DOC notifications. A no-result can mean there is no matching record, the local jail is not feeding that record to the notification system, the person is in a different custody track, or the search data is incomplete.
The Missouri DPS MOVANS notice is useful for understanding how local jail, court, and DOC alerts fit together.
A separate DPS notice said May 2026 notification changes required updated SMS or email registration, so older alert settings should not be assumed to keep working.
Grundy County Detention Facilities
The facility map for Grundy County is simple. The only detention facility in the county assigned its own page is the sheriff-operated county jail and law enforcement center. No Missouri Department of Corrections adult prison, Federal Bureau of Prisons facility, or ICE detention facility was identified inside Grundy County.
- Grundy County Jail / Grundy County Law Enforcement Center - local adult detention facility for pretrial detainees, local sentenced misdemeanants, court holds, transfer holds, and short-term law-enforcement custody.
People arrested by Trenton Police, the sheriff's office, or MSHP may start in local custody. Once a case changes status, the record may move toward Case.net, MODOC, BOP, ICE, or a records request rather than a county roster result.
Grundy County Custody Terms
Custody terms can sound similar, but they point to different records. These plain-English definitions help separate a jail population count from a jail record search and a court case search.
- Booking
- Jail intake after arrest, including identity checks, property handling, fingerprints, a booking photo, and agency paperwork when those steps apply.
- Pretrial custody
- Custody before a case is resolved, often while bond, first appearance, or later court events are pending.
- Sentenced custody
- Custody after a court sentence. In the Vera 2019 county jail data, Grundy County had 16 people listed in sentenced custody.
- Detainer
- A hold request from another agency, such as another county, probation/parole, federal authorities, or immigration officials.
- Disposition
- The court outcome of a charge, which is not the same thing as the original jail booking charge.
Grundy County Inmate Population FAQ
How big is the Grundy County inmate population? Vera reports a 2019 total jail population of 20 for Grundy County and a rated capacity of 30. That is the latest county jail row in the Vera file, not a current 2026 jail count.
Is there an official Grundy County web jail roster? No official public web roster, current-inmate table, or booking-photo gallery was located on the county or sheriff pages reviewed. Use the sheriff's phone line, in-person contact, MOVANS/VINELink, MSHP reports, Case.net, and records requests as appropriate.
Where do sentenced state inmates appear? After a state prison sentence or state supervision placement, search MODOC systems rather than the county jail. MODOC web search covers active offenders, while Sunshine offender data can include active and historical supervision records.
Can a released person still have a court case? Yes. Release from jail does not end the criminal case. Case.net may show later hearings, bond changes, warrants, dispositions, and sentencing entries after the person leaves local custody.
