¶ U.S. Immigration and Customs Enforcement
U.S. Immigration and Customs Enforcement is the DHS component most directly visible in the Garfield County source cluster. The local evidence involves an ICE check-in office and hold-room facility in Glenwood Springs, ERO detention and deportation functions, HSI criminal-investigative collaboration, and public disputes over whether local cooperation complied with Colorado limits on civil immigration enforcement.
- ICE lists a Glenwood Springs check-in office at 100 Midland Avenue, Suite 210, under the Denver Field Office.
- Colorado Times Recorder reporting based on federal data identifies the Glenwood Springs hold room as
GSCHOLD.
- Glenwood Springs' notice of violation says the city approved a 2003 special use permit for a GSA detention center for the Bureau of Immigration and Customs Enforcement and alleges later hold-time violations.
- Garfield County Sheriff's statements refer to local ICE agents monitoring the public jail website and requesting release-timing notification.
The May 2026 CTR refresh adds a Greeley lane. CTR reports that an unmarked office at 4645 W. 18th Street, suite 500 in Greeley was confirmed by Denver ICE public affairs as an HSI suboffice, and reports that many HSI suboffices have hold rooms for temporary detention. Treat this as a reported facility / agency-infrastructure relationship until direct ICE/DHS facility files, lease records, inspection records, hold-room datasets, or local-government records are retained.
¶ ERO and HSI distinction
- ERO is the ICE function most closely connected in the local source set to detention, release notifications, transfers, deportation, and check-in / field-office operations.
- HSI is the ICE function most closely connected to criminal-investigative collaboration: the 2010 ICE-led operation, SPEAR's official HSI collaboration language, and the 2025 Luis Rivas Martinez case materials.
- The fresh Greeley article is another reminder to keep HSI and ERO distinct. An HSI suboffice or HSI hold room does not by itself prove ERO transfer, deportation, civil-immigration enforcement, or long-term detention in that location.
- The source set should not treat HSI collaboration as civil ERO cooperation unless a source specifically connects an HSI action to ERO transfer, detention, deportation, or civil immigration enforcement.
- The repo does not yet have a direct ICE facility file, inspection report, lease, interagency agreement, or full hold-room dataset package for Glenwood Springs.
- The repo also does not yet have direct ICE/DHS facility, lease, inspection, hold-room, or detainee-count records for the reported Greeley HSI suboffice.
- ICE official sources describe offices and operations from the agency's perspective; they do not resolve local-law compliance questions.
- Current local allegations about ERO transfer pathways require stronger original records or court findings before being written as settled fact.
