Mason County Inmate Population
The Mason County inmate population is centered at the Mason County Detention Center, a full-service jail in Maysville. The county says the jail opened in 1990 and houses people for Mason, Bracken, Fleming, and Lewis Counties, along with state inmates. That local fact matters. A count listed for Mason County is not limited to Mason County residents or Mason County arrests. It can include a person arrested in a nearby county, a sentenced Class D inmate held in a county bed, or a person waiting on transfer or release steps.
The jail is operated through the elected Mason County Jailer, Lisa Kern Yeary, while the Mason County Sheriff handles law-enforcement work such as sheriff records, arrests, incident reports, and open-records requests. The Kentucky Department of Corrections weekly jail reports provide the most useful public population snapshots. Those reports show bed count, reported population, sex and security categories, Class D inmates, controlled intake, parole violators, and federal inmates for each listed jail.
Mason County Inmate Statistics
The June 4, 2026 KY DOC weekly jail report listed Mason with 131 jail beds and a reported population of 135. That placed the jail at 103 percent of listed capacity, or four people above the report's bed count. The same report listed 37 Class D inmates, 19 people marked community-custody eligible, four controlled-intake inmates, two parole violators, and zero federal inmates.
| Measure | Figure | Source / Date |
|---|---|---|
| Reported jail population | 135 | KY DOC Weekly Jail Report, June 4, 2026 |
| Rated jail beds | 131 | KY DOC Weekly Jail Report, June 4, 2026 |
| Capacity percentage | 103% | KY DOC Weekly Jail Report, June 4, 2026 |
| Class D inmates | 37 | KY DOC Weekly Jail Report, June 4, 2026 |
| Federal inmates | 0 | KY DOC Weekly Jail Report, June 4, 2026 |
Mason County Jail Population Trends
Sampled DOC weekly reports show a lower Mason County jail count in 2026 than in the 2023 and 2024 snapshots found in the research file. The figures should not be read as an annual average, because they are point-in-time weekly reports. They do show that Mason County Detention Center has been above listed bed capacity in each sampled report.
| Date | Beds | Reported Population | Capacity Note |
|---|---|---|---|
| Jan. 5, 2023 | 131 | 175 | 134%, 44 over capacity |
| June 6, 2024 | 131 | 180 | 137%, 49 over capacity |
| Dec. 5, 2024 | 131 | 157 | 120%, 26 over capacity |
| June 4, 2026 | 131 | 135 | 103%, 4 over capacity |
The June 2026 count can also be compared with the FRED and Census estimate of 16.936 thousand Mason County residents in 2025. That rough calculation equals about 797 jailed people per 100,000 county residents, but it is not an official local incarceration rate because the jail also holds people for other counties and for Kentucky state custody.
Mason County Custody Breakdown
The Mason County inmate population is split across secure and non-secure categories in DOC reporting. On June 4, 2026, secure male custody was the largest category. Secure female custody, non-secure male custody, and non-secure female custody were reported separately. The labels come from DOC weekly jail reporting and should not be treated as public housing assignments for a specific inmate.
| Category | Population | Notes |
|---|---|---|
| Secure male | 94 | Included 29 Class D inmates, four controlled-intake inmates, and two parole violators. |
| Secure female | 22 | Included eight Class D inmates. |
| Non-secure male | 16 | All 16 were listed as community-custody eligible. |
| Non-secure female | 3 | All three were listed as community-custody eligible. |
| Total | 135 | Reported against 131 listed beds. |
Laws for Mason Jail Data
Kentucky law shapes what can be seen, requested, or withheld. The Mason County jail roster is the fastest path for current custody facts, but the Kentucky Open Records Act and jail rules govern many records that are not posted online. The Mason County Sheriff's open-records page also gives a local process for sheriff-held records, including the five-business-day response period and copy fees.
Key public-record and jail rules:
KRS 61.870 defines public records and Kentucky booking photographs for open-records purposes.
KRS 61.872 and KRS 61.878 cover inspection rights and exemptions, including some law-enforcement investigative records.
KRS 61.8746 restricts commercial pay-for-removal use of booking and inmate photographs.
KRS 532.100 explains why certain Kentucky felony offenders may serve in county jails.
501 KAR 3:090 covers jail medical-care standards and coroner notification after a death in custody.
Mason County State Inmates
Mason County Detention Center is a county jail, not a Kentucky DOC prison. Still, state inmates are part of the Mason County inmate population because Kentucky uses county and regional jails for some sentenced prisoners. The KY DOC KOOL information page says the Kentucky Online Offender Lookup is a public service and warns that offender data newer than 120 days may not be finalized.
The state context is large. The DOC 2024 annual report said Kentucky's local facilities housed an average total of 19,667 prisoners per month, including 7,457 state prisoners. KACo reported that 36 percent of state inmates in Kentucky were housed in county jails as of November 2024. For Mason County, that means a person can be in the county jail roster while also fitting a state-inmate category in DOC reporting.
Search Mason County Inmates
The current Mason County inmate search starts at the detention center's Current Inmates page, which routes to the Public Safety Cloud JailTracker roster. The direct roster path is the Mason agency page for JailTracker. It is a JavaScript app, so a browser with scripts enabled is needed before full search results and profiles appear.
The roster covers current county-jail custody and state inmates housed at the Mason County Detention Center. It does not replace KOOL for sentenced offenders who have moved into DOC tracking, the BOP locator for sentenced federal inmates, or the ICE locator for immigration detention.
- Open the Mason current-inmates page or the direct JailTracker roster for MASON_COUNTY_KY.
- Search by offender name, starting with the last name when the full name is uncertain.
- Add a first name or use fewer letters if the search returns too many or too few matches.
- Complete any captcha shown by the app before expecting results.
- Open the profile for charges, holds, bond, court fields, booking details, and photo support when present.
- If no local result appears, check KOOL, VINELink, BOP, ICE, or call the jail.
Mason County Roster Fields
JailTracker exposes a search route for the Mason agency and includes name-search, current-offender, captcha, and profile functions. The app shell did not show every live field without JavaScript execution, so the search fields should be read as supported or observed app fields rather than a promise that every control appears in the same way on every screen.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| AgencyName | Route parameter | Yes | MASON_COUNTY_KY identifies the Mason agency in JailTracker. |
| Offender name search | Text search | Unspecified | The client includes offender search by name. |
| Last name | Text | Likely optional until submitted | Best starting point for common searches. |
| First name | Text | Likely optional | Useful for narrowing common last names. |
| Search type | Option control | Unspecified | Live options were not visible from the static shell. |
| Current offenders only | Boolean filter | Unspecified | Client includes current-offender-only behavior. |
| Captcha | Image/text challenge | Conditional | The app includes captcha validation fields. |
The official detention roster source is shown in the county manifest screenshot of the Mason current-inmates frame.
The frame matters because it confirms the county detention site is the local entry point before the JailTracker vendor roster opens.
Mason County Inmate Records
A Mason County inmate record is a custody summary, not the full criminal case file. JailTracker client fields support names, booking number, jacket number, facility, original book date and time, final release date, arresting agency, charge descriptions, arrest code, court type, case numbers, warrant numbers, bond type, bond amount, fine amount, status, and hold information. Photo fields are also supported by the app, but a live profile should be checked to confirm whether a photo is displayed for a specific inmate.
- Booking
- Administrative intake after arrest, including identification, property, and custody setup.
- Bond
- Money, security, or release conditions set to help assure court appearance.
- Detainer or hold
- Another agency's legal request or authority that can keep a person in custody.
- Class D inmate
- A Kentucky felony category that may be housed in a county jail under state law.
- KOOL
- Kentucky Online Offender Lookup, the state DOC offender search.
Mason County Lookup Fallbacks
A failed roster search does not always mean the person is not in custody. A new booking may not be posted yet, a name may be spelled differently, a release may have occurred, or the person may be held in another system. The jail phone line, records-request process, state DOC lookup, VINELink, BOP, and ICE locator each cover a different part of the custody chain.
| System | Use It For | Where to Start |
|---|---|---|
| Mason JailTracker | Current county-jail custody and state inmates housed locally | Current Inmates page or direct Public Safety Cloud roster |
| Jail phone or in person | Very recent bookings, visitation, deposits, or custody questions | Mason County Detention Center, (606) 564-3621 |
| Sheriff open records | Sheriff-held arrest, incident, or law-enforcement records | Mason County Sheriff open records |
| KY DOC KOOL | Sentenced offenders and state custody records | Kentucky Online Offender Lookup |
| VINELink | Release, transfer, escape, or parole-hearing alerts | VINELink or 1-800-511-1670 |
| BOP or ICE | Federal sentenced inmates or immigration detention | BOP locator or ICE detainee locator |

Mason County Detention Facilities
The facility map for Mason County resolves to one local detention facility. The county detention center is still a regional custody point because it houses people for Mason, Bracken, Fleming, and Lewis Counties, plus state inmates.
- Mason County Detention Center - county jail and full-service detention center for pretrial detainees, sentenced county inmates, state inmates, and regional county custody.
Mason County Jail Services
Once custody is confirmed, the county FAQ points visitors and families toward video visitation, commissary deposits, phone accounts, mail rules, and medication handling. Video visitation runs through Inmate Sales, and onsite visits use a lobby kiosk after scheduling. The FAQ says inmates may receive up to two free 15-minute onsite video visits per week, while onsite and offsite visits are recorded and monitored.
Commissary money can be sent by money order, lobby kiosk, or JailATM. Phone time is separate and can be purchased through Inmate Sales, a lobby kiosk, or 1-877-998-5678. The FAQ also warns that commissary may be stopped for 30 days on both inmates if the jail believes money is being routed through another inmate to avoid jail fees.
Mason County Inmate FAQ
How large is the Mason County inmate population? The June 4, 2026 KY DOC weekly jail report listed 135 people against 131 beds at Mason County Detention Center. Earlier sampled reports listed 175 in January 2023, 180 in June 2024, and 157 in December 2024.
Does the Mason County jail hold only Mason County arrests? No. The official county detention page says the jail houses inmates for Mason, Bracken, Fleming, and Lewis Counties, as well as state inmates. That is why roster and population data can include people outside a simple Mason arrest search.
Where are Mason County court charges found? JailTracker may show custody-facing charges and court dates, but filed charges, amendments, dispositions, and convictions belong in Kentucky Court of Justice records. The court records after jail arrest page explains that pathway.
Is there a Mason County sheriff inmate app? No official Mason County Kentucky sheriff app with inmate roster, warrant search, or custody lookup was found. The Maysville PD tip411 app is for anonymous tips and agency content, not jail lookup.
