The Sumner County Inmate Population
The Sumner County inmate population is centered on one local detention building, the Sumner County Detention Facility in Wellington. The Sumner County Sheriff's Office operates the jail and describes it as an adult-only facility open every day. Local custody begins there for adults arrested by the sheriff, municipal police departments, the Kansas Highway Patrol, court warrants, or other authorized agencies. The roster also showed U.S. Marshals housing entries during the research pass, so the Sumner County inmate population can include federal pretrial detainees held by contract even though the building is not a Bureau of Prisons facility.
Count changes are driven by arrest intake, bond and release decisions, court commitments, work-release approvals, and transfers. A person booked on a local case may leave the Sumner County jail after bond, after a court order, or after serving a short local sentence. A person sentenced to Kansas Department of Corrections custody should be checked through KASPER after transfer, not only through the county roster. That split matters because the Sumner County inmate population page is about local jail custody, while state prison and federal custody are separate systems with separate lookup tools.
Sumner County Inmate Population Statistics
The strongest current local figures are the jail's published bed capacity and the roster count captured during research. The Sumner County Sheriff's Office About Us page states that the sheriff manages a 185-bed detention facility. The official roster displayed 88 inmates when inspected on June 13, 2026. That roster count is a point-in-time number, not an annual average daily population. Sumner County did not publish an official annual jail population dashboard in the reviewed sources.
| Measure | Figure | Source / Year |
|---|---|---|
| Current roster count | 88 inmates | Sheriff jail roster, inspected June 13, 2026 |
| Rated capacity | 185 beds | Sheriff About Us page, inspected June 13, 2026 |
| Point-in-time occupancy | About 47.6% | Derived from 88 divided by 185 |
| County population estimate | 22,312 residents | U.S. Census QuickFacts, July 1, 2025 estimate |
| Point-in-time jail rate | About 394 per 100,000 residents | Derived from roster count and 2025 county estimate |
| National local jail rate | 198 per 100,000 U.S. residents | BJS Jail Inmates in 2023, midyear 2023 |
Sumner County Inmate Population Trends
Sumner County publishes a live jail roster, but the official county and sheriff sources reviewed did not publish a multi-year average daily population series, annual bookings, or average length of stay. That limits trend analysis. The current roster count can be compared with published capacity, county population, and national jail context, but it should not be treated as a yearly average.
The research also found one older correctional-population data point outside current county publications. It is useful only as context because it is not a fresh official Sumner County dashboard. Modern use should rely first on the sheriff roster for current custody and on KORA requests when a historical record is needed.
| Year or Date | Sumner Jail Count / Capacity | Notes |
|---|---|---|
| 2013-12-31 | 151 | Historical correctional-population context noted in research, not a current county dashboard |
| 2026-06-13 | 88 current roster / 185 beds | Official sheriff roster count and sheriff-published capacity |
| 2024-2026 | ADP not published | No official Sumner multi-year average daily population table located |
Who Makes Up the Sumner County Inmate Population
The Sumner County inmate population is adult custody only. The sheriff states that the detention facility books male arrestees and females, and the public roster publishes age, sex, and race per inmate. It does not publish an aggregate race, age-band, gender, felony, misdemeanor, or pretrial status table. That means demographic claims should stay at the field level unless the sheriff releases a summary.
- Adult custody: The detention page says the jail holds adult persons only.
- Male and female bookings: The sheriff's About Us page says both male arrestees and females are booked there.
- Arresting agencies: Sample roster entries included the sheriff, Wellington Police Department, Belle Plaine Police Department, Kansas Highway Patrol, and U.S. Marshals.
- Hold types: Examples included serving sentence, probation or parole violation, failure to appear, and U.S. Marshals housing.
Note: The roster's age, sex, and race fields describe individual entries, not a full published Sumner County demographic summary.
Sumner County Jail Capacity
The Sumner County Detention Facility capacity is published as 185 beds. Using the roster count captured on June 13, 2026, the point-in-time occupancy was about 47.6%. That calculation is simple and useful, but it is not the same as an official occupancy report across a month or year. No official overcrowding dashboard, new jail construction notice, closure notice, consent decree, or recent conditions litigation summary was located in the county, sheriff, or state sources reviewed for this build.
The facility still has multiple roles. It handles county and municipal bookings, local sentences, work release, contracted housing, and U.S. Marshals housing entries shown on the roster. A capacity figure alone does not show classification needs, medical needs, separation needs, or court-transport load. For current population status, use the roster and jail phone. For broader data, use a Kansas Open Records Act request through the county.
Laws Governing Sumner County Inmates
Kansas law explains why jail rosters, jail books, and related public records are generally available while still allowing exemptions for some records. The county KORA overview says the county must act on a request as soon as possible and not more than three business days after receipt. The county may provide records, explain when and how records will be provided, or state why a record cannot be released.
Key Statutes:
K.S.A. 45-215 is the Kansas Open Records Act title section and the starting point for public-record access.
K.S.A. 45-221 lists records that may be closed, with law-enforcement annotations that include jail books and mug shots.
K.S.A. 19-811 gives the sheriff charge and custody of the county jail and prisoners.
K.S.A. 19-1930 explains why U.S., city, and corrections prisoners can be received into a county jail.
K.S.A. 19-1935 requires a KBI inquiry after the death of a city or county prisoner in custody.
Sumner County and State Prison
No Kansas Department of Corrections state prison is physically located in Sumner County. The KDOC facilities map lists Kansas correctional facilities in places such as El Dorado, Hutchinson, Lansing, Wichita, and Winfield, but not Sumner County. Nearby south-central Kansas facilities may matter after sentencing, yet they should not be treated as local Sumner County jail pages.
After a felony sentence to KDOC custody, lookup shifts to KASPER, the Kansas Adult Supervised Population Electronic Repository. KDOC says KASPER provides resident location and status and is updated daily excluding weekends. It also warns that KASPER is not a complete criminal history. A person may start in the Sumner County inmate population before court, then later appear in state corrections records after transfer.
Search the Sumner County Inmate Population
The official Sumner County jail roster is the main current-custody search. It is a free sheriff page, not a separate vendor portal. The roster showed a name field and booking-number field during research, plus paginated current inmate results. A current inmate entry can show charges, bond, arresting agency, booking date and time, age, sex, race, and an image area.
- Open the sheriff's jail roster and start with the Name field when the booking number is unknown.
- Search by last name first because roster names display last-name-first.
- Use the Booking Number field when a number such as B26000000122 is known.
- Read the charge, bond, agency, and date fields in the list result before assuming the court case is final.
- If the person is missing, call the jail information line because new bookings may take time to process.
The image manifest identifies a screenshot from the official Sumner County jail roster, showing the search fields and current inmate result layout.
The roster screenshot reinforces the main search pattern: name and booking number are the practical starting points for a current Sumner County inmate lookup.
Sumner County Roster Search Fields
The public roster field set is narrow, which makes the search simple but also means common names may need extra review. The page did not state minimum characters, wildcard rules, or a required field. Because the list itself contains the key record fields, the user should compare name, age, booking date, arresting agency, charges, and bond before deciding whether the match is correct.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Name | Text | Unspecified | Names display last-name-first in roster results. |
| Booking Number | Text | Unspecified | Examples use a B followed by digits, such as B26000000122. |
| Pagination | Numbered links | Not applicable | Multiple result pages were visible when inspected. |
Past Sumner County Inmate Records
The sheriff roster appears to be a current-inmate list. The research did not locate a published retention window for released inmates or an archive of old booking entries. If a person has already left the Sumner County inmate population, use the jail phone for basic release confirmation and the county KORA channel for a formal record request. Sumner County's KORA freedom of information officer is Debra Norris, Sumner County Clerk, at the county courthouse.
For a court case, use Kansas Case Search after charges are filed. For a state prisoner, use KASPER. For a federal sentenced prisoner, use the BOP locator. For immigration custody, use ICE ODLS. That sequence keeps the local roster from being mistaken for a complete criminal-history database.
What a Sumner County Inmate Record Shows
A current roster record is a custody snapshot. It is not the same thing as a conviction record or a full court file. It can show the jail's booking number, charge text, bond amount, arresting agency, booking date and time, age, sex, race, and image area. Housing unit, court date, projected release date, magistrate, and case-link fields were not observed in the public roster text.
| Field | What It Shows in Sumner County |
|---|---|
| Name | Last name, first name, and middle name or suffix when available. |
| Booking Number | A public booking identifier, such as B26000000122. |
| Charges | Kansas statute references or charge text, sometimes separated by vertical bars. |
| Bond | Numeric bond amount; zero may appear on sentence or U.S. Marshals housing entries. |
| Arresting Agency | The agency responsible for the arrest or custody entry. |
| Image | An image area or booking photo beside the public roster entry. |
County Jail vs State Prison
The Sumner County jail roster and the KDOC locator answer different questions. The county roster is best for adult local custody right after arrest, during pretrial detention, for short local sentences, and for some U.S. Marshals housing at the county jail. KASPER is the statewide tool for KDOC-funded or KDOC-operated supervision and custody. It should be used after a state sentence or transfer.
| County Jail | State Prison / KDOC | |
|---|---|---|
| Who Is Held | Pretrial adults, local sentenced inmates, work release, and agency holds | People under Kansas Department of Corrections custody or supervision |
| Run By | Sumner County Sheriff's Office | Kansas Department of Corrections |
| Where to Look | Sumner County jail roster | KASPER offender search |
| Limit | Current roster, not a full criminal history | Not a complete criminal-history record and not updated on weekends |
State and Federal Inmate Search
Federal custody has its own split. A federal pretrial person may appear on the Sumner roster if physically housed at the county jail under U.S. Marshals arrangements. A federal sentenced person should be searched through the BOP Inmate Locator. Immigration custody should be checked through ICE ODLS, and ICE's detention facilities directory is the place to verify an ICE facility's current visiting rules.
Victims and family members who need release, transfer, or escape alerts can use VINELink. Sumner's detention page says custody data transfers from the jail to VINE every 15 minutes and that registration is free and confidential.
Sumner County Detention Facilities
Official research located one detention facility physically in Sumner County for this project. Municipal agencies may arrest people in Wellington, Caldwell, Belle Plaine, Oxford, Conway Springs, and other communities, but the published adult custody endpoint is the county jail in Wellington.
- Sumner County Detention Facility holds adult male and female arrestees, pretrial detainees, local sentenced inmates, approved work-release inmates, contracted housing, and U.S. Marshals housing shown on the roster.
