Martin County Inmate Population
The Martin County inmate population has two very different meanings. For arrests made by the Martin County Sheriff's Office, Kentucky State Police, or other local agencies, the normal jail path is Big Sandy Regional Detention Center in Paintsville. That regional jail serves Johnson, Lawrence, Magoffin, and Martin counties, so a person booked after a Martin County arrest appears in a Big Sandy regional roster rather than a Martin County-only roster. The Kentucky Association of Counties regional jail authority explainer identifies Big Sandy as the regional jail authority serving those four counties.
The second count is federal. USP Big Sandy is physically in Inez and is operated by the Federal Bureau of Prisons. It is not the Martin County jail and it does not use the Big Sandy Regional Detention Center roster. A person serving a federal sentence at USP Big Sandy is searched through BOP, while a person sentenced into Kentucky Department of Corrections custody is searched through KOOL. That split matters because the same county name can point to local jail custody, state prison records, or federal prison records.
Martin County Inmate Statistics
Official Big Sandy Regional Detention Center pages inspected in June 2026 did not publish a rated capacity, jail construction year, pod layout, or official average daily population. The most reliable local jail figure located was the Prison Policy Initiative correctional population locator's 2020 vintage listing for Big Sandy Regional Detention Center. That figure is a local facility population count, not a rated capacity. For USP Big Sandy, the BOP public facility data is more direct because it gives a current facility total and separates the main penitentiary from the camp.
Kentucky's broader incarceration level helps place Martin County custody in context. The Prison Policy Initiative Kentucky profile reports a statewide incarceration rate of 889 per 100,000 people. That statewide rate is not a Martin County jail count. It is useful background when comparing the small regional jail count to the much larger federal population at USP Big Sandy.
| Measure | Figure | Source / Date |
|---|---|---|
| Big Sandy Regional Detention Center rated capacity | Not located in official sources | Official Big Sandy pages inspected June 2026 |
| Big Sandy Regional Detention Center local facility population | 215 | Prison Policy Initiative 2020 vintage correctional population locator |
| USP Big Sandy total population | 1,312 | BOP public facility data, June 4, 2026 |
| USP Big Sandy main penitentiary | 1,218 | BOP public facility data, June 4, 2026 |
| USP Big Sandy satellite camp | 94 | BOP public facility data, June 4, 2026 |
| Kentucky incarceration rate | 889 per 100,000 people | Prison Policy Initiative Kentucky profile |
Martin County Inmate Trends
The trend data for the Martin County inmate population is uneven because no official Martin-only jail dashboard was located. Big Sandy Regional Detention Center is a multi-county jail, so its total count includes people from Johnson, Lawrence, Magoffin, and Martin counties. A single Big Sandy number cannot be treated as a Martin County-only daily jail count. The safest use of the available figures is to state what each source measures and avoid blending local jail, state prison, and federal prison counts into one false total.
Local reporting in late 2025 gave recent Big Sandy Regional Detention Center average daily population context, but those points were not an official government data table. They still help explain why a roster can feel busy even when no capacity figure is published. The federal side is clearer: BOP published a June 4, 2026 count for USP Big Sandy, and that count is much larger than the 2020 local jail population point.
| Year / Date | Population Figure | How to Read It |
|---|---|---|
| 2020 vintage | 215 at Big Sandy Regional Detention Center | Local correctional facility population, not rated capacity and not Martin-only |
| November 2025 | 241 average daily population | Nonofficial local news context, reported as a regional jail ADP point |
| December 18, 2025 | 225 count | Nonofficial local news context, reported for Big Sandy Regional Detention Center |
| June 4, 2026 | 1,312 at USP Big Sandy | Official BOP federal prison count, split between USP and camp |
Martin County Jail Capacity
No official rated bed capacity for Big Sandy Regional Detention Center was located in the inspected jail pages. That absence should not be filled with the 2020 population count. Capacity means how many beds or people a jail is approved to hold. Population means how many people were counted at a point in time or across an average period. Big Sandy's official pages publish the address, phone, roster path, office hours, visitation, commissary, programs, and several service links, but they do not publish a capacity table.
The public demographic detail is also limited. Big Sandy's JailTracker system can expose individual fields such as name, booking date, agency, release date, charges, case data, and housing details when configured. It does not publish a Martin County demographic dashboard by sex, age, race, pretrial status, or sentence status. USP Big Sandy is more explicit about its population type: BOP identifies it as a high-security U.S. penitentiary with an adjacent minimum-security camp for male federal offenders.
Capacity note: Big Sandy's official capacity was not located. Treat the 215 figure as a 2020 local facility population count, not a bed rating.
Martin County Inmate Laws
Kentucky public-records law controls how jail, sheriff, court, and corrections records are requested, but each agency keeps its own records. A Martin County sheriff incident report should be requested from the sheriff or the proper local custodian. A regional jail booking record should start with Big Sandy Regional Detention Center. A court file should start with the Martin County Circuit Court Clerk or the Kentucky Court of Justice public tools. A state prison file belongs with KY DOC, and a federal prison record belongs with BOP.
Key Kentucky rules:
KRS 61.870 defines public records, official custodians, and custodians under the Kentucky Open Records Act.
KRS 61.872 and KRS 61.878 set the right to inspect public records and the exemptions that can limit access.
KRS 61.8746 addresses commercial use of booking photographs or official inmate photographs.
501 KAR 13:010 sets minimum health and life-safety standards for covered Kentucky jails.
501 KAR 3:090 includes jail medical procedures and coroner notice if a prisoner dies in custody.
Martin County Inmate Programs
Big Sandy Regional Detention Center advertises several programs that can affect the lived shape of the regional jail population. The official program page lists GED, Work Release, Church Meetings, Moral Reconation Therapy, Portal, and National Career Readiness Certificate programming. The page does not publish eligibility rules, class schedules, or completion requirements, so families should confirm access with jail staff rather than assuming every person in custody can enroll.
Recent conditions context is specific and should be read with care. On December 4, 2023, the U.S. Attorney's Office for the Eastern District of Kentucky announced an agreement with Big Sandy Regional Jail Authority to ensure access to medications for opioid use disorder under the ADA. That source concerns medication access and disability rights. It is not a full medical policy manual for the jail, and no official grievance or sick-call instructions were located in the inspected Big Sandy pages.
Search Martin County Inmates
The official Martin County inmate search path starts with Big Sandy Regional Detention Center's inmate search link, because local and regional jail custody is handled there. The Big Sandy inmate search frame routes users into the JailTracker public roster for Big Sandy Reg Det Center, KY. That roster is the practical place to check current local custody and, when enabled, released records.
The official roster path is important because many search results for a Martin County jail roster do not point to a Martin County-operated jail. The regional jail site itself also links to VINE, KOOL, court dockets, CIDNET phones, TouchPay commissary, and other services. If the roster app does not load or a very recent arrest is missing, the next step is to call Big Sandy at 606-297-5245. For arresting-agency context, Martin County Sheriff's Office is listed at 606-298-2828.
The roster screen source is the official Big Sandy inmate search frame.
Martin County Roster Steps
Use the Big Sandy roster first for a person who may have been arrested locally, booked before first appearance, held on a district or circuit case, or released recently. Search by last name first. If too many results appear, add the first name or middle name. The older official grid sorts by last name and can show release dates when released records are included.
Roster charges are booking data. They can differ from formal court charges after review by a prosecutor or a judge. If the roster shows a charge, bond, or court time, compare it with the Kentucky Court of Justice docket. If the person is not listed, use the fallback chain instead of assuming there was no arrest.
- Open the official Big Sandy inmate search page from the detention center site.
- Let JailTracker load and search by last name first.
- Add first name, middle name, offender ID, or date filters if the app exposes those fields.
- Use Include Released only when the person may have bonded out, transferred, or been released.
- Open the matching record row and compare booking date, agency, charges, bond, and release status.
- If no match appears, check KOOL, BOP, ICE, VINELink, and the court docket as the case type requires.
Martin County Search Fields
The Big Sandy roster has two field sets in the research. The older official JailTracker grid shows displayed roster values and an Include Released checkbox. The newer public roster shell has a broader search form, but the inspection found that the newer publicroster API rejected the old facility code. For users, that means the safest entry point is still the official Big Sandy inmate search link, followed by the linked JailTracker app.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Grid Search | Text search | Unspecified | Searches displayed roster values in the older public grid. |
| Include Released | Checkbox | Optional | Use only when a person may no longer be in current custody. |
| Last Name | Result column and clickable key | Primary search clue | The older grid sorts by last name ascending. |
| First Name | Text or result column | Optional | Helps narrow common last names. |
| Middle Name | Text or result column | Optional | Useful for matching people with the same first and last name. |
| Book Date | Result column | Not a search requirement | Shows original booking or intake date when published. |
| Release Date | Result column | Not a search requirement | Appears for released records when released records are shown. |
Martin County Inmate Records
A Big Sandy JailTracker record can show the jail side of a case, not the full court file. Research from the app scripts found a detainee detail container with Charges and Housing tabs when the facility exposes the relevant settings. Charge data can include case numbers, bond type, bond amount, fine amount, sentence, court time, charge status, control number, arrest code, charge description, warrant number, crime type, counts, modifier, offense date, arrest date, and arresting agency.
Some fields exist in the software but may not be visible to the public in every record. Housing details and images are examples. The roster should be used as a custody and booking record, then checked against court dockets and clerk records for formal filings, amendments, dispositions, and orders.
| Field | What It Shows |
|---|---|
| Agency | Agency or facility context, if enabled in the grid. |
| ArrestNo / Jacket | JailTracker arrest or internal inmate number, if published. |
| Name | Last, first, and middle name. |
| Book Date | Original booking or intake date and time. |
| Release Date | Final release date and time for released records. |
| Charges tab | Charge status, code, description, warrant number, count, bond, court type, and dates when visible. |
| Cases grid | Case number, bond type, amount, fine amount, sentence, and court date. |
| Housing tab | Housing detail may exist, but public visibility depends on facility settings. |
Martin County Released Records
The Include Released option is the first place to look when a person may have bonded out, served a short stay, or been transferred. If a released record no longer appears, ask Big Sandy which custodian handles regional jail booking records and whether a written Kentucky Open Records Act request is needed. For sheriff arrest or incident reports, contact Martin County Sheriff's Office rather than sending the request to KY DOC.
State records follow a separate path. KOOL covers Kentucky DOC offenders and warns that entries are updated daily and offender data newer than 120 days may not be finalized. Federal records have their own path through BOP. Court records after a jail arrest are searched through Kentucky Court of Justice dockets, KYeCourts guest access, or the Martin County Circuit Court Clerk, depending on the record needed.
The state source captured for sentenced Kentucky offenders is the KY DOC KOOL information page.
Martin County Jail Lookup
The main lookup mistake is using the wrong system. Big Sandy Regional Detention Center is the local and regional jail for Martin County arrestees. KY DOC KOOL is for sentenced Kentucky offenders and some state inmates housed in jails. BOP is for federal inmates, including people at USP Big Sandy. ICE ODLS is for immigration detention, not ordinary county jail custody.
| Custody Type | Who Is Held | Where to Search |
|---|---|---|
| Regional jail | Pretrial detainees, local inmates, and some short-sentence or regional holds from Martin and nearby counties | Big Sandy JailTracker through the official detention center site |
| Kentucky state custody | Sentenced Kentucky offenders after DOC placement or state custody processing | Kentucky Online Offender Lookup |
| Federal prison | Sentenced federal inmates, including USP Big Sandy prisoners | BOP inmate locator |
| Immigration custody | People held by ICE or processed through immigration detention systems | ICE Online Detainee Locator System |
Martin County Federal Search
USP Big Sandy gives Martin County a large federal custody presence, but that population is not a county jail population. BOP identifies USP Big Sandy as a high-security federal penitentiary with an adjacent minimum-security satellite camp for male offenders. Search the BOP inmate locator by register number, DCDC number, FBI number, INS number, or by name with optional age, race, and sex fields. BOP results can show name, register number, age, race, sex, release date, and location.
Federal pretrial custody can be different from sentenced BOP custody. A person with a federal case may be held by the U.S. Marshals Service and housed under contract before sentencing. No Martin County-specific USMS public roster was located. For immigration detention, use ICE ODLS by A-number and country of birth, or by biographical details. For custody alerts, VINELink is available through the Big Sandy and KY DOC ecosystem.
The federal facility source is the official BOP USP Big Sandy page.
Martin County Detention Facilities
Two facilities are central to Martin County inmate population research. The first is the regional jail that serves local arrest custody. The second is a federal prison located inside the county. No Kentucky DOC state prison and no ICE detention facility were located in Martin County official materials, so state and immigration lookups use statewide or federal locator systems.
- Big Sandy Regional Detention Center holds local and regional jail detainees from Johnson, Lawrence, Magoffin, and Martin counties, including Martin County arrestees.
- USP Big Sandy holds male federal sentenced offenders at the high-security penitentiary and adjacent minimum-security satellite camp in Inez.
Martin County Custody Terms
Short terms in jail and court records can change the meaning of a search result. These definitions help separate a roster entry from a court order or DOC record.
- Booking
- Jail intake after arrest, including identity, charge entry, and custody setup.
- Detainer
- A hold from another agency that can stop release even when a local bond is posted.
- PR bond
- Personal recognizance release, where the court allows release based on a promise to appear.
- Classification
- Jail review used to assign housing, security level, and some program access.
- Disposition
- The court result of a charge, such as dismissal, plea, conviction, or other order.
Martin County Inmate FAQ
Is there a Martin County jail roster? Martin County does not appear to run a separate Martin-only public jail roster. Local custody searches normally use the Big Sandy Regional Detention Center roster because that regional jail serves Martin County along with Johnson, Lawrence, and Magoffin counties.
How large is the Martin County inmate population? No official Martin-only jail population dashboard was located. The best local jail population point found was the 2020 vintage Prison Policy Initiative count of 215 at Big Sandy Regional Detention Center, while BOP reported 1,312 inmates at USP Big Sandy on June 4, 2026.
When should KOOL be used? Use KOOL after a person has moved into Kentucky DOC custody or when the jail roster no longer shows the person after sentencing. KOOL is updated daily, and KY DOC warns newer offender data may not be finalized for 120 days.
Does the Big Sandy roster show released inmates? The researched JailTracker grid includes an Include Released checkbox. Use it when a person may have bonded out, transferred, or finished a short stay. If the record is not visible, call Big Sandy and ask about the official records custodian.
Is USP Big Sandy the county jail? No. USP Big Sandy is a federal Bureau of Prisons facility in Inez. It is physically in Martin County, but it is searched through BOP rather than the regional jail roster.
Was an official local app found? No official Martin County, Kentucky sheriff app or Big Sandy Regional Detention Center app was located. Search results found similarly named sheriff apps from other states, which should not be used for Martin County, Kentucky custody searches.
