Dukes County Inmate Population Snapshot
The Dukes County inmate population is held through one sheriff-operated facility, the Dukes County Jail and House of Correction. The jail page describes the facility as the county jail, regional lock-up, and house of correction for Martha's Vineyard. It houses male detainees awaiting trial, county inmates serving sentences up to 2.5 years, and short-term lock-up detainees from the six island towns. That makes the Dukes County inmate population narrower than a state prison count and more local than a federal inmate search.
Several public sources count the Dukes County inmate population in different ways. The sheriff's page gives a local maximum. Massachusetts Sheriffs' Association reporting gives design capacity, average count, and monthly average daily population. Department of Public Health inspection records give a snapshot from the date inspectors were inside the jail. Those figures are not interchangeable. They describe different dates, housing units, and reporting rules. Current custody still starts with the jail control desk because no official online Dukes County jail roster was located in the sheriff, county, or Mass.gov sources reviewed for Dukes County.
Dukes County Inmate Population Statistics
Recent official data places the Dukes County inmate population in the low teens to high teens. The Massachusetts Sheriffs' Association county population reports list a December 2025 custody average daily population of 17.71 and a June 2025 custody average daily population of 13.47. The MSA operational-capacity report for July 1-Dec. 31, 2025 lists one building, 50 design-capacity housing-unit beds, and an average population count of 14. A Department of Public Health inspection snapshot recorded 16 inmates on Dec. 18, 2025.
The official Dukes County government about page places the year-round county population at about 20,933 residents in 2024, which gives the jail data local context. Dukes is an island county with a small year-round base and a much larger seasonal load. That is why the jail's regional lock-up role matters. A person arrested in Aquinnah, Chilmark, Edgartown, Gosnold, Oak Bluffs, Tisbury, or West Tisbury may move through the same sheriff facility, even though the case may later be handled by a court or a state agency.
| Measure | Figure | Source / Date |
|---|---|---|
| Sheriff-stated jail maximum | 40 male detainees | DCSO jail page, accessed June 17, 2026 |
| Design capacity | 50 housing-unit beds | MSA operational-capacity report, July 1-Dec. 31, 2025 |

Dukes County Inmate Population Trends
The Dukes County inmate population has moved within a narrow band in the available 2024 and 2025 monthly ADP reports. June 2024 was 17.70 custody ADP, December 2024 dropped to 12.00, June 2025 was 13.47, and December 2025 rose to 17.71. The trend does not show a large-county jail pattern with hundreds of people moving in and out each day. It shows a small regional jail where a few changes in pretrial custody, pre-arraignment safekeep status, or county sentences can move the reported average.
The 2025 Chapter 126 row listings add more detail without naming individual people. Across Q1-Q4, the research derived 76 booking rows from official reports. Q4 2025 listed 19 booking rows, including 15 pretrial admissions and 4 sentenced admissions. Q3 2025 listed 26 booking rows, with 24 pretrial and 2 sentenced. These are not the same as the sheriff's FY2019 admission note, so the safest reading is that different reports use different scope, terms, and data fields.
| Year / Month | ADP or Count | Notes |
|---|---|---|
| June 2024 | 17.70 custody ADP | MSA monthly ADP report |
| December 2024 | 12.00 custody ADP | MSA report also lists 14.00 supervised population |
| June 2025 | 13.47 custody ADP | Includes pretrial, sentenced, and pre-arraignment safekeep categories |
| December 2025 | 17.71 custody ADP | Includes pretrial male, sentenced male, and safekeep categories |
| Dec. 18, 2025 | 16 inmates | DPH inspection snapshot |
Dukes County Jail Capacity
Capacity for the Dukes County inmate population must be read with attribution. The sheriff's public jail page says the facility houses a maximum of 40 male detainees. The MSA operational-capacity report lists 50 design-capacity housing-unit beds across one building. The 2024 PREA regional lock-up audit lists a designed capacity of 20 for the lock-up component and an average daily population of 2 over the prior 12 months. Each number describes a specific use of the same local correctional complex.
The MSA July-Dec. 2025 housing-unit breakdown shows maximum housing, medium sentenced housing, pre-release, lockup, and holding-cell areas. DPH inspection materials from late 2025 also matter. The inspection report found deficiencies and stated that the facility did not comply with cited correctional-facility regulations, with later DPH concern about overcrowded conditions in plan-of-correction responses dated Jan. 20 and Jan. 29, 2026. That conditions context should not be converted into a roster count. It is a facility oversight fact tied to a specific inspection cycle.
| Unit | Capacity | Average Count | Function |
|---|---|---|---|
| Unit 1 | 6 | 2 | Max housing, occupied |
| Unit 2 | 12 | 4 | Max housing dormitory, occupied |
| Unit 3 | 6 | 5 | Medium sentenced housing, occupied |
| Unit 4 | 6 | 3 | Medium sentenced housing, occupied |
| Pre-Release | 6 | 0 | Unoccupied in the report period |
| Lockup | 6 | 0 | Police lockup only |
| Holding Cells | 8 | 0 | Police lockup only |
Laws on Dukes County Inmate Data
Massachusetts law explains why some Dukes County inmate population information is public while some personal jail, medical, juvenile, sealed, or investigatory details may be withheld. The main path for jail-held records is the public-records process through the sheriff's Records Access Officer. Court records after arraignment follow Trial Court public-access rules and MassCourts availability, which is a separate system. Chapter 126 reporting is especially useful because it requires non-identifying admissions, release, race, ethnicity, sentence, credits, program, bail, and disposition fields from county corrections reporting.
Key Massachusetts rules:
M.G.L. c.66 s.10 sets the public-record request and response framework, including the general 10-business-day response period.
M.G.L. c.4 s.7 cl.26 defines public records broadly while preserving exemptions for privacy, investigations, and other protected material.
M.G.L. c.126 s.40 requires sheriffs to record and report non-identifying admissions, release, and jail-population data fields.
M.G.L. c.6 s.167 defines CORI, which affects access to criminal justice agency information about charges, custody, and release.
Where Dukes County Holds Inmates
The Dukes County inmate population is not spread across a county campus of separate jails. The official facility map identifies only the Dukes County Jail and House of Correction at 149 Main Street in Edgartown. No Massachusetts DOC prison, Bureau of Prisons institution, ICE detention facility, or separate municipal jail was located in official Dukes County sources. Local police may arrest or temporarily handle a person, but the sheriff's jail page says DCSO maintains the regional lock-up for all six Martha's Vineyard towns.
The official Dukes County Sheriff's Office homepage describes a broader public-safety office that includes the Jail, Regional Lock-Up and House of Corrections, Regional Emergency Communications Center, Civil Process Department, and Community Outreach programs. Sheriff Robert W. Ogden leads the office, and DCSO's executive page identifies Special Sheriff Kayla Pachico, who is also the Records Access Officer named in the public-records request process.
This screenshot comes from the official Dukes County Sheriff's Office homepage, which is the starting point for the local jail, directory, divisions, public records, and facility pages.
The homepage does not function as an online roster, but it points readers toward the sheriff office that operates the county jail and regional lock-up.
Search Dukes County Inmate Population
No official Dukes County online inmate roster, current-inmate list, recent-booking feed, or mugshot gallery was located. That fact changes the search workflow. The first route for a current custody question is the jail control desk at 508-627-5173. Written documentation goes through Special Sheriff Kayla Pachico, Records Access Officer, at records@dcsoma.org, fax 508-627-8496, P.O. Box 252, Edgartown, MA 02539, or the physical address at 149 Main Street.
After arraignment, a court case may be searchable through MassCourts eAccess, but MassCourts is not a live jail roster. It may show party, event, docket, and disposition details where public and available. Mass.gov guidance says most criminal cases are available online by docket number, so a docket number from court paperwork or the clerk's office can be crucial.
- Call the Dukes County Jail and House of Correction control desk at 508-627-5173 for current county custody questions.
- Ask whether the person is in jail custody, regional lock-up status, released, or not held by DCSO.
- For written proof, request a specific booking sheet, custody status record, booking date, or release date from the Records Access Officer.
- Search MassCourts or call the clerk after arraignment if the question is about charges, hearings, or case status.
- Use the Massachusetts DOC, BOP, or ICE locator only when the person is no longer in local county jail custody.
Dukes County Roster Search Fields
A normal jail roster page would have name, booking number, date, or housing search fields. Dukes County does not have an official online county roster form in the research file. That means there are no public DCSO roster fields to enter online. The search-field table below preserves the actual finding rather than filling in fields from another county.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Online roster field | Not available | Not available | No official Dukes County online roster form was located. |
| Records Access Officer | Contact route | Yes for written requests | Special Sheriff Kayla Pachico receives public-records requests for DCSO. |
| Description of requested records | Written detail | Strongly recommended | Request a booking sheet, custody status record, booking date, release date, or booking photo if sought. |
The DCSO public-records request page says written requests are recommended, though not required, because they help the office respond accurately and completely. Requests should reasonably describe the specific records sought. The office may assess reasonable fees under some circumstances.
Dukes County Inmate Record Fields
Because there is no official online roster profile, a Dukes County inmate record should be described as a set of possible records, not a guaranteed public web page. Massachusetts retention schedules identify arrest records, booking sheets, fingerprint cards, warrants, subpoenas, RMV reports, and vehicle inventories as related arrest or booking record categories where applicable. Chapter 126 reporting adds non-identifying fields such as race and ethnicity, admission type, release type, sentence length, jail credit, earned time, program outcomes, bail amount or no-bail reason, and case disposition.
| Field | What It Shows |
|---|---|
| Booking sheet | Jail intake or booking information, when releasable under public-record rules. |
| Arrest record | Documents arrest and booking for alleged civil or criminal violations. |
| Type of admission | Whether the report category is pretrial, sentenced, or another admission type. |
| Type of release | How a person left custody or changed status in the reporting data. |
| Sentence length | Sentence length for sentenced county inmates where reported. |
| Bail amount or no-bail reason | A Chapter 126 field tied to Trial Court source data and availability limits. |
Dukes County Jail vs State Prison
The Dukes County inmate population includes local pretrial detainees, pre-arraignment safekeeps, and county-sentenced inmates serving short sentences. A person committed to a Massachusetts state prison is not searched through the county jail. Mass.gov says users can find a person held in a Massachusetts DOC facility through the Massachusetts prison inmate lookup path, which points to VINELink and phone support. Massachusetts VINE participation is limited, and no DCSO page confirms Dukes County jail participation.
| County Jail | State Prison | Federal or ICE | |
|---|---|---|---|
| Who is held | Pretrial, pre-arraignment, and short county sentences | Sentenced state prisoners | Federal sentenced inmates or immigration detainees |
| Agency | Dukes County Sheriff's Office | Massachusetts Department of Correction | BOP, ICE, or federal district custody path |
| Where to look | Jail phone and records request | Massachusetts DOC and VINELink path | BOP inmate locator or ICE ODLS |
| Dukes County caveat | No official online roster located | No DOC prison located in Dukes County | No BOP or ICE detention facility located in Dukes County |
Dukes County State Federal ICE Search
State, federal, and immigration searches cover different custody systems. The Massachusetts Department of Correction path is for sentenced state prisoners, not a county jail roster. Massachusetts VINELink can support notifications in participating systems, but the research found no official Dukes County jail VINE roster page. The Federal Bureau of Prisons inmate locator covers federal inmates from 1982 to the present. ICE Online Detainee Locator System searches immigration custody by A-number and country of birth or by name, country of birth, and date of birth.
These systems should not be mixed. A person arrested in Dukes County may be in the local jail before arraignment, in state DOC custody after a state-prison commitment, in BOP custody after a federal sentence, or in ICE custody if immigration detention applies. A detainer is a hold or notice from another agency that may affect release, but it does not turn the county roster into a federal or immigration locator.
Dukes County Detention Facilities
The facility list for Dukes County is deliberately short. Official county, sheriff, Mass.gov, MSA, PREA, DPH, BOP, and ICE source checks identified one local detention facility in Dukes County. The jail page should be read as both the county jail and the regional lock-up, not as one part of a larger local jail network.
- Dukes County Jail and House of Correction - county jail, house of correction, and regional lock-up serving all six Martha's Vineyard towns.
The official county about page places Dukes County on Martha's Vineyard and the Elizabeth Islands. That geography shapes custody logistics, court transport, and visitation planning. It also explains why a single Edgartown facility can be the main detention point for several towns.
Dukes County Jail Programs
The sheriff's jail page gives local program detail that helps explain what is happening inside the small Dukes County inmate population. DCSO lists education, vocation, addiction, anger management, self-help, HiSET exam proctoring, Edovo tablets, mindfulness sessions, reading club, online courses, parenting courses, guest speakers, and an inmate labor or road crew program. The Human Services Division works with each inmate on a care plan covering education, medical needs, dental needs, mental-health needs, and community support where available.
Medical intake is another local detail. DCSO says the Health Services Unit performs a medical intake on every pretrial detainee and inmate placed in sheriff custody. Medical care can include physicals, acute care, sick calls, dental care, eye care, and mental-health treatment. Those services do not create a public medical record. They explain part of the jail intake process and why a booking record may not contain every fact a family member wants.
