When USMS Applies
USMS custody applies after a federal court order, during federal pretrial detention, and during transport until acquittal, release, conviction, or delivery to BOP. Local jails can temporarily house federal detainees, so a Dolores County release entry may mean transfer to USMS custody.
This page is not a federal prison locator. Use Federal Bureau of Prisons for federal sentenced inmates from 1982 to present, and use USMS or the federal court record for pretrial custody and transport questions.
How to Follow a USMS Transfer
- Ask the Dolores County sheriff whether the release reason was USMS transport or federal hold transfer.
- Check the federal court docket for release, detention, bond, acquittal, conviction, or commitment orders.
- Use USMS public custody and detention information for agency role and FOIA route.
- If the person was convicted and designated, move to the BOP locator.
- If immigration custody follows, use ICE ODLS separately.
USMS Records Route

Research sources state that USMS is responsible for confinement, care, and transportation of federal prisoners from court-ordered custody until acquittal or conviction and delivery to BOP.
The USMS FOIA source says agency records, including records on prisoners in USMS custody, may be requested through FOIA. That is separate from a Colorado CCJRA request to the Dolores County sheriff. A local request can show that the person left the county jail to USMS; a federal request or court record may be needed to follow what happened after the handoff.
Federal Pretrial Chain
USMS is often the bridge between a local jail hold and federal court. After an initial federal hearing, a person may be released by the federal court or remanded to the custody of the U.S. Marshal. After conviction, USMS delivers the person to an institution, which may later create a BOP locator record. Before that BOP stage, the BOP locator may not answer the question.
For Dolores County, a sheriff release to USMS should be treated as a transfer. The person may be housed in a contract facility, transported for federal proceedings, released by the federal court, acquitted, convicted, or delivered to BOP. The local release date marks the end of county custody, not necessarily the end of detention.
Federal Court Records
The federal court docket can be the most useful companion to a USMS transfer. It may show detention orders, bond or release orders, plea and sentencing events, acquittal, conviction, revocation, or commitment to BOP. If the Dolores County release record says USMS, check the federal case activity before assuming the person is in BOP or back in the community.
USMS custody and BOP custody are different stages. USMS handles custody and transport from court-ordered custody until acquittal or conviction and delivery to BOP. BOP handles federal sentenced custody and release-date records after designation. ICE may be a later separate path if immigration custody follows a federal or local release.
Records Request Split
A Dolores County sheriff records request should ask for the local booking and release fields: booking date, release date, release reason, hold type, case number, and transfer destination. A USMS FOIA request should be considered only for federal agency records. Those two requests have different legal frameworks, custodians, and response processes.
When the person was temporarily held locally for a federal agency, the county record may be short. It may show that the county jail no longer held the person and that USMS assumed custody. The federal trail then belongs to the federal court, USMS, BOP, or another receiving agency, depending on what happened next.
County Records and Federal Records
The sheriff can usually confirm that a person left local custody to USMS, but ongoing location or federal-release details may belong to federal court, USMS, BOP, or ICE. A CCJRA request to the sheriff and a federal FOIA request are different processes.
Dolores County Release Context
Dolores County's small rural profile makes the receiving agency especially important in a release record. USAFacts reports about 2,500 residents in 2025, and research did not find a local automated release portal. When the release reason points to USMS, the next record path is federal custody and court documentation.
Reconciling USMS Sources
USMS should be used when the local record, court record, or federal case context points to federal pretrial custody or transport. The Dolores County sheriff can confirm a local booking and release to USMS. The federal court docket can show the order that placed the person in federal custody or released them from it. USMS records can explain custody and transport. BOP records become relevant only after a federal sentence and BOP designation.
A local release to USMS can be misunderstood because the word release appears in the county record. In that setting, release means release from Dolores County custody, not necessarily release from detention. The person may be moved to a federal contract facility, transported for hearings, released by a federal court, acquitted, convicted, or delivered to BOP. The receiving agency and federal case status decide the next source.
USMS FOIA is a separate records route from a sheriff CCJRA request. A county request can ask for local booking and release fields, including transfer destination. A federal request can ask for USMS agency records where available. The federal court docket may be easier to check first because it can show public case events without waiting for an agency records response.
For a Dolores County reader, the most efficient order is sheriff release reason, federal court docket, USMS role, then BOP or ICE if the case moves there. That sequence keeps pretrial custody, sentenced federal custody, and immigration custody from being treated as the same system.
USMS Is Not BOP
USMS and BOP are often confused in release searches. USMS handles federal custody and transport tied to court orders, including pretrial detention and movement after hearings. BOP handles federal sentenced custody after designation and maintains the federal inmate locator from 1982 forward. A Dolores County release to USMS may not create a BOP result right away, and it may never create one if the person is released by the federal court before a BOP commitment.
That distinction changes the records path. A Colorado CCJRA request to the sheriff can ask for the local booking and release record, including whether the destination was USMS. A USMS FOIA request may be needed for federal agency records. The federal court docket may show whether the person was detained, released, acquitted, convicted, or committed. BOP becomes useful only when the case reaches the BOP stage.
For Dolores County, always start with the local release reason. "Released to USMS" is not the same as "released from custody." It is a transfer phrase that should trigger federal court and USMS follow-up before any conclusion about current location.
Verification Boundaries
USMS information answers federal custody and transport questions, while the sheriff answers the local release event. Use the federal court docket and BOP locator when the case moves beyond USMS transport.
