Access Rock Mountain Releases

To find someone released from Rock Mountain Detention Facility, treat the record as a San Diego County Sheriff's jail release unless a transfer record shows another agency took custody. Rock Mountain is currently a county maximum-security detention facility, even though older references may point to its federal contract history. Confirm releases through Who's In Jail, the facility, court records, VINE, Records & ID, CPAC, or the receiving agency.

Rock Mountain Release Records

Rock Mountain Detention Facility is a San Diego County Sheriff's maximum-security facility in Otay Mesa at 446 Alta Road, Ste. 5400. The Sheriff's page says construction was completed in 2000, the facility was leased to the federal government and operated by Corrections Corporation of America for its first 15 years, returned to the Sheriff's Office in 2016, and began renovations in 2019. House 1 opened in July 2023 with a rated capacity of 200. That history is the distinctive release-record issue for Rock Mountain.

Older search results or references may blur federal, private, and county custody at this location. For current San Diego release research, Rock Mountain is a Sheriff facility. A release should be confirmed through the Sheriff's custody record, the facility phone, Records & ID, court records, VINE, CPAC, or Probation where applicable. If a person was actually in federal custody, then BOP, federal court, or another federal source may apply. The record must identify the agency that held the person at release.

Confirm Rock Mountain Release Status

Begin with the Sheriff's Who's In Jail lookup. Search by first and last name, then record the booking number, listed facility, charge or case references, and release date if shown. The Sheriff's current lookup includes a warning that release dates may be inaccurate while records are recalculated, so call the custody information line when the exact release status matters.

If the person no longer appears, move to the release-confirmation chain. Rock Mountain is not a permanent public release archive. The court file can show bail, dismissal, sentence, custody credits, transfer, or probation. Records & ID can handle formal booking and release records. VINE may provide release, pending release, or transfer notification if registration was completed before the event. CPAC and Probation matter if the person left the facility for a structured local program or supervision.

  1. Search Who's In Jail while the record may still be live.
  2. Call (619) 409-5000 and select Rock Mountain Detention Facility.
  3. Use San Diego Superior Court records to confirm the release authority.
  4. Check CPAC or Probation when the release involved county programs or supervision.
  5. Use CDCR, BOP, or ICE only when the county record points to that receiving agency.

Rock Mountain Records Contact

Rock Mountain's facility page lists 446 Alta Road, Ste. 5400, San Diego, CA 92158, with the Sheriff's custody information line. Formal release-record requests should go through Records & ID, which processes arrest and booking records and identifies in-custody inmates. When the issue is a transfer, provide the booking number and court case number so the records office can distinguish release to the community from release to another agency.

The Sheriff's crime, arrest, and accident report page lists a $20.00 copy fee, with exceptions for certain first copies. The local criminal history route can require valid photo ID and has a 3-10 business day processing goal. Those request paths are slower than a phone check, but they produce better documentation after the live roster entry is gone.


Rock Mountain Facility History

Rock Mountain's history is the main reason its release page should not read like a generic jail page. The facility was completed in 2000, leased to the federal government, operated by CCA for its first 15 years, returned to the Sheriff's Office in 2016, and reopened a custody unit after renovation in July 2023. A reader may find an older page, article, or court reference that makes the site look federal or private. Current release verification should begin with the San Diego Sheriff unless the date or record clearly points to federal custody, and the release date should be matched to the agency operating the facility at that time.

That distinction protects against a common error. A BOP result saying "Not in BOP Custody" does not confirm a county jail release from Rock Mountain. A Sheriff's record saying released from Rock Mountain does not confirm final federal discharge. The agency at the moment of release controls the record. For a county jail release, use Sheriff's records and court records. For federal custody, use BOP or federal court. For ICE transfer, use ICE ODLS and immigration counsel or court.

Rock Mountain Otay Mesa Checks

Rock Mountain sits in the same Otay Mesa custody geography as George Bailey, East Mesa, Richard J. Donovan, and Otay Mesa Detention Center. Those names are not interchangeable. George Bailey and East Mesa are Sheriff facilities. Richard J. Donovan is CDCR state prison. Otay Mesa Detention Center is an ICE contract detention facility. A person can move between systems, but each move should leave a transfer or receiving-agency trail.

When a Rock Mountain record is unclear, compare the facility name, booking number, court case, and release reason. If the person was moved to another Sheriff's facility, Who's In Jail may still show an active county record. If the person moved to CDCR, CIRIS may become relevant. If ICE is involved, the county release reason and ICE locator should be reconciled before describing the person as released to the community.


Rock Mountain ICE Transfers

San Diego's border-county context makes ICE checks a practical part of some release confirmations. A county jail release can mean transfer to immigration custody. Use ICE ODLS, facility contact, counsel, or immigration court if the record suggests ICE involvement. The local research also notes debate over pending-release information and Sheriff-to-ICE transfers, but the release page's job is factual confirmation: identify the county release reason and the next custody system.

Note: Because Rock Mountain has an older federal/private history, verify both the date and agency before choosing a locator.
