Costilla County Inmate Population Overview
The Costilla County inmate population starts with the Costilla County Jail and Sheriff's Office detention function in San Luis. The facility map identifies Costilla County Jail as the primary in-county detention facility. It also identifies Conejos County Jail and Las Animas County Jail as out-of-county housing partners because official Costilla County materials discuss housing Costilla inmates in those jails. That makes the local inmate population broader than one building, even though the local sheriff remains the first point for county custody questions.
The population count includes people arrested locally, pretrial detainees awaiting advisement or bond, people held on warrants or detainers, people awaiting transfer, and short local sentences allowed by Colorado law. It does not include sentenced Colorado prison inmates after transfer to the Colorado Department of Corrections. It also does not include federal sentenced prisoners in BOP custody or immigration detainees searched through ICE ODLS, unless a local hold or contract housing question connects them to a county jail.
Costilla County is rural and geographically large. Vera Incarceration Trends classifies it as rural and lists a land area of 1,227.593 square miles in its 2025 row. A few jail admissions, releases, transfers, or out-of-county placements can change the population rate sharply because the local denominator is small.
Costilla County Inmate Population Statistics
The best sourced population table in the research file is the Vera Institute Incarceration Trends county dataset for Costilla County FIPS 08023, accessed June 1, 2026. No county-published current average daily population, annual bookings total, or current jail capacity page was located. Vera's recent rows show zeros or blanks for several jail fields. Treat those values as a dated trend dataset and possible reporting gap, not proof that the jail had no one in custody.
| Measure | Figure | Source / Year |
|---|---|---|
| County FIPS | 08023 | Vera Incarceration Trends, Costilla County row |
| Urbanicity | Rural | Vera 2025 row |
| Land area | 1,227.593 square miles | Vera 2025 row |
| Jail rated capacity | 24 | Vera 2019 row |
| Total jail population | 20 | Vera 2019 row |
| Total jail population | 20.67 | Vera 2021 row |

| Jail population rate | 991.08 per 100,000 age 15-64 residents | Vera 2019 row |
Costilla County Inmate Population Trends
The trend table shows why recent Costilla County population data must be handled with care. Vera reports nonzero jail population values through 2021, then zero values in later rows along with capacity values that fall to zero or blank by 2024 and 2025. The research file did not locate a county explanation for those later values. They may reflect reporting change, missing data, changed housing practice, or another source issue. Do not treat them as a current closure finding.
| Year | Total Jail Pop / ADP-like Field | Rated Capacity | Notes |
|---|---|---|---|
| 2018 | 16 | 23 | Vera shows 12.67 pretrial custody and 3.33 sentenced custody. |
| 2019 | 20 | 24 | Vera shows 19 pretrial, 1 sentenced, and 47.5 admissions. |
| 2020 | 11.75 | 21.06 | Vera shows 7.5 pretrial and 4.25 sentenced custody. |
| 2021 | 20.67 | 22.83 | Vera shows 17.67 pretrial and 3 sentenced custody. |
| 2022 | 0 | 18 | Vera row has zero jail population and admissions with 16 discharges. |
| 2023 | 0 | 12 | Vera row has zero jail population and admissions with 84 discharges. |
| 2024-2025 | 0 | 0 or blank | No county-published current ADP or capacity source was located. |
Costilla County Inmate Population Makeup
Vera's demographic rows give a partial look at who made up the Costilla County inmate population in the years where jail data was reported. The most useful breakdown is pretrial versus sentenced custody. In 2019, Vera shows 19 people in pretrial custody and 1 sentenced custody. In 2021, it shows 17.67 pretrial and 3 sentenced. That pattern supports the local custody explanation: the county jail population is mostly people awaiting court, bond, transfer, or short local disposition.
- Pretrial custody: Vera reports 19 in 2019 and 17.67 in 2021, the largest jail-population category in those rows.
- Sentenced custody: Vera reports 1 in 2019 and 3 in 2021, separate from sentenced state-prison custody.
- Sex breakdown: Vera reports male and female values for older rows, but 2021 and later sex fields are zero or blank.
- Race and ethnicity: Vera includes Latinx and white jail-population fields for older rows, with later gaps.
- State prison transfer: A person sentenced to CDOC is searched through the state locator after transfer, not the local jail.
Costilla County Jail Capacity
Costilla County's current county-published rated capacity was not located. Vera lists historical capacity values of 24 in 2019, 22.83 in 2021, 18 in 2022, and 12 in 2023. The 2024 and 2025 capacity values are zero or blank. Because those later values do not come with a county explanation, the more accurate statement is that a current official capacity source was not found.
Official Costilla County materials still show jail planning and out-of-county housing context. A May 6, 2025 Board of County Commissioners agenda included a jail designs update and an agreement with Las Animas County to house Costilla County inmates. A Dec. 22, 2025 notice described a work session with Conejos County officials to discuss housing Costilla County inmates in the Conejos County jail. Those facts help explain why the mapped inmate population includes serving jails outside Costilla County.
Laws Governing Costilla Jail Records
Colorado law supplies the public-records framework for the Costilla County inmate population. County jail custody is tied to the sheriff under Colorado jail statutes. Public access to records is governed by CORA and CCJRA, while booking photographs and sealed records have additional limits. These laws do not create a Costilla County online roster by themselves, but they do shape how a person asks for booking, custody, mugshot, or official-action records.
Key Statutes:
C.R.S. Title 24, Article 72, Parts 2 and 3 governs Colorado public records and criminal-justice records, including CORA and CCJRA.
C.R.S. §§ 17-26-101 to 17-26-103 and C.R.S. § 30-10-511 recognize county jail custody and sheriff responsibility for county prisoners.
C.R.S. § 24-72-305.5 addresses booking photographs and misuse tied to commercial mugshot publication or paid removal.
Colorado Jail Standards and C.R.S. § 30-10-606 provide death-response and custody-investigation context.
Search Costilla County Inmate Population
No official public online Costilla County Jail roster was located. That means the inmate population search starts with the sheriff and records request channels, not a web roster field. The current sheriff page lists office phone 719-672-0673, dispatch 719-672-3302, fax 719-672-1091, and a records email at costillacountyco@gmail.com. The page says Sheriff's Office records requests may be submitted by email, mail to Attention: Records Request, P.O. Box 6, San Luis, CO 81152, or in person at 103 Gaspar Street in San Luis.
The official Costilla County Sheriff's Office page is the local source for sheriff contact, bonding links, records-request instructions, and response-protocol notices.
The screenshot supports the local records route used when no Costilla County online roster is available.
- Call the Sheriff's Office or dispatch and ask whether the person is in local custody.
- Provide full name, date of birth or age, and arrest date if known.
- If phone confirmation is not enough, submit a written CCJRA or CORA request for official-action or booking records.
- Check Costilla Combined Court if the question is about filed charges or a hearing date.
- Use CDOC, BOP, ICE, or VINELink only when the custody stage fits that system.
Costilla County Roster Search Fields
A true county roster search-field table cannot be filled because the research did not locate an official Costilla County public roster form. Instead, the table below shows the available official lookup channels and their fields. It keeps the same practical purpose without claiming a local search form exists.
| System | Fields or Information Used | Use |
|---|---|---|
| Costilla Sheriff's Office | Full name, DOB or age, arrest date, case or warrant number if known | Current local custody and booking-record requests. |
| Colorado docket search | Date range plus case number, party last name, party first name, or attorney last name | Court dates and case entries after arrest. |
| CDOC Offender Search | DOCNO, last name, first name, gender, CAPTCHA | Sentenced Colorado prisoners after transfer. |
| BOP Inmate Locator | Federal number or first, middle, last, race, age, sex | Federal inmates from 1982 to present. |
| ICE ODLS | A-number and country of birth or biographical search | Immigration detainee location where covered. |
Costilla County Inmate Record Details
A requested Costilla County inmate record should be framed by specific fields. Since no public roster profile was found, do not claim a public page displays mugshots, charges, bond, housing, or release status online. Ask the Sheriff's Office for the booking or official-action information that answers the custody question.
| Field | What It Shows |
|---|---|
| Booking date and time | When the person was processed after arrest or surrender. |
| Arresting agency | Which agency made or presented the arrest. |
| Booking charges | Early arrest or warrant authority, not necessarily final court charges. |
| Bond amount and type | Cash, surety, PR release, property, or no-bond status where available. |
| Custody location | Costilla County Jail or possible out-of-county housing location. |
| Release or transfer status | Whether the person remains in custody, was released, or moved to another agency. |
County Jail State Prison Search
Costilla County inmate population searches often fail when the wrong system is used. A person arrested yesterday may not appear in CDOC. A person sentenced to prison may no longer be searchable through the local jail phone line. A federal detainee may not appear in BOP if the person is in pretrial U.S. Marshals custody. ICE detention is another separate path.
| Custody Type | Where to Look | What It Covers |
|---|---|---|
| County jail | Costilla County Sheriff's Office and jail records request | Local arrest, pretrial custody, short local sentence, release or transfer status. |
| State prison | Colorado Department of Corrections Offender Search | Sentenced Colorado prison custody, facility assignment, sentence fields, and parole dates. |
| Federal prison | BOP Inmate Locator | Federal inmates from 1982 to present. |
| Immigration detention | ICE Online Detainee Locator System | Immigration detainee location when ODLS coverage applies. |
| Notifications | VINELink | Custody or release notifications where the facility or state participates. |
The CDOC Offender Search form documents the state-prison fields used after a Costilla County defendant becomes a sentenced Colorado prisoner.
CDOC's search page is useful after state-prison transfer, not for the first hours of a county jail booking.
Costilla County Detention Facilities
The facility map has three pages because Costilla's detention picture includes one in-county jail and two serving jails named in official Costilla County materials. The primary county jail should be checked first. The out-of-county jails matter only when the sheriff, court record, or official notice indicates the person was housed there.
- Costilla County Jail - the primary county jail and sheriff detention function in San Luis for local arrests and county custody questions.
- Conejos County Jail - an out-of-county jail discussed in a Costilla County notice as a possible place to house Costilla inmates.
- Las Animas County Jail - an out-of-county jail tied to a Costilla County agenda item about an agreement to house Costilla inmates.
Costilla Court Mugshot Records
Court records and mugshot records answer different questions. A court record after arrest shows filed charges, hearings, bond orders, case numbers, charge status, and document-copy routes. A booking photo, if available and releasable, is held by the law-enforcement or jail custodian. Colorado's booking-photo statute, C.R.S. § 24-72-305.5, addresses booking photographs and misuse linked to commercial mugshot publication or paid removal.
Costilla County research found no public jail mugshot gallery. The correct route is a records request to the Sheriff's Office. For charge status, use the Colorado docket search and Costilla Combined Court. For booking photos and public-access limits, use the Costilla County jail mugshots page.

The research did not locate a county-published current jail population, so the Vera data should be treated as historical trend data rather than a live count.
Is there a Costilla County Jail roster online? No official public online Costilla County Jail roster was located in the research file. Current custody checks should start with the Sheriff's Office phone line, dispatch, or a written records request.
Can a released inmate be found? No official released-inmate archive was located. Ask the Sheriff's Office for booking or official-action records, then check Costilla Combined Court for filed charges or hearing records.
Does CDOC show Costilla County jail inmates? CDOC is for sentenced Colorado prison custody. It is not the first place for pretrial county jail custody after a local arrest.
Are Costilla County booking photos online? No official jail mugshot gallery was located. Booking-photo access uses the Sheriff's Office records request process and Colorado booking-photo law.
