¶ Garfield County ICE/DHS activity and law-enforcement chronology
This timeline tracks dated source-grounded evidence of ICE, DHS, HSI, ERO, Garfield County Sheriff and jail, SPEAR, and Glenwood Springs municipal activity or disputes in Garfield County. It separates official self-description, primary records, local reporting, and advocacy allegations.
- The Garfield County Jail opens in Glenwood Springs, according to the GCSO jail page.
- Why it matters: this establishes the detention institution later implicated in release-notification and ICE-transfer disputes.
- Source basis: Garfield County ICE/DHS law-enforcement source cluster
- Glenwood Springs approves a special use permit for a General Services Administration detention center for the Bureau of Immigration and Customs Enforcement at the Midland Center property, according to the city's 2026 notice-of-violation packet.

- Source basis: Garfield County ICE/DHS law-enforcement source cluster
- ICE announces the end of a five-day HSI-led multi-agency operation in western Colorado. The release says GCSO and Carbondale Police Department provided significant assistance; Silt Police Department and other agencies also participated; ERO coordinated detention and deportation.
- Why it matters: this is direct official evidence of local Garfield County law-enforcement assistance to HSI, while also separating HSI investigation from ERO removal functions.
- Source basis: Garfield County ICE/DHS law-enforcement source cluster
- ACLU of Colorado and the Colorado Coalition Against Domestic Violence send a letter challenging GCSO referrals of domestic-violence victims' booking reports to ICE.
- Why it matters: this documents an earlier public dispute over local information-sharing with ICE.
- Evidence layer: advocacy / legal correspondence.
- Source basis: Garfield County ICE/DHS law-enforcement source cluster
- ACLU and news materials describe Sheriff Lou Vallario as defending the policy challenged by the ACLU / CCADV letter.
- Why it matters: this indicates the 2012 dispute was public and contested, not only internal correspondence.

- Source basis: Garfield County ICE/DHS law-enforcement source cluster
- GCSO says TAG and TRIDENT merged into SPEAR.

- Source basis: Garfield County Sheriff's Office and Jail
- Garfield County announces BOCC approval of Resolution 2024-05 declaring Garfield County a non-sanctuary county. The press release includes Sheriff Vallario's statement that the jail notifies ICE of release timing but cannot hold a person more than the state-law release window once criminal custody ends.
- Why it matters: this is the clearest official county-level source for the county's public non-sanctuary posture and the Sheriff's release-notification self-description.
- Source basis: Garfield County Board of County Commissioners
- The 2026 cease-and-desist packet includes an email exchange in which Roaring Fork Schools asks about safe-haven policy language and Sheriff Vallario states a duty to work with and cooperate with law-enforcement agencies including ICE.
- Why it matters: this is a school-facing cooperation dispute lead, but it currently rests on excerpts inside an advocacy packet.
- Evidence layer: embedded CORA excerpt in legal-demand packet.
- Source basis: Garfield County ICE/DHS law-enforcement source cluster
- GCSO publishes the Sheriff's position statement on ICE. Vallario says Colorado officers have no federal immigration authority, ICE holds are usually civil / administrative, ICE reviews the public jail website, the jail provides release timing when ICE asks, and the jail cannot unnecessarily delay release.

- Source basis: Garfield County Sheriff's Office and Jail
- The 2026 cease-and-desist packet includes a Vallario email discussing proposed Colorado immigration restrictions, task forces, ICE access to secure jail areas, and release windows.
- Why it matters: this is a direct internal-record lead for how the Sheriff understood proposed cooperation limits, but the full CORA production is still needed.
- Evidence layer: embedded CORA excerpt in legal-demand packet.
- Source basis: Garfield County ICE/DHS law-enforcement source cluster
- A SPEAR case record identifies a June 3, 2025 assist-agency incident involving Luis Armando Rivas Martinez in Glenwood Springs. The cease-and-desist packet alleges SPEAR assisted HSI and transported Rivas for an ERO custody transfer.

- Evidence layer: primary case summary plus advocacy packet allegations.
- Source basis: Garfield County Sheriff's Office and Jail
- A federal ICE hold-room waiver memo changes the relevant hold-room time-limit context from 12 hours to 72 hours, according to Glenwood Springs' 2026 notice-of-violation packet.

- Source basis: Garfield County ICE/DHS law-enforcement source cluster
- Colorado Times Recorder reporting based on federal data says the Glenwood Springs hold room,
GSCHOLD, held 73 detainees during the covered period.

- Evidence layer: advocacy / legal-demand packet.
- Source basis: Garfield County ICE/DHS law-enforcement source cluster
- Aspen Public Radio publishes local reporting on the cease-and-desist letter and links the demand packet and SPEAR case report.

- Source basis: Garfield County ICE/DHS law-enforcement source cluster
- Colorado Times Recorder publishes reporting on Colorado ICE hold rooms, including the Glenwood Springs facility at 100 Midland Avenue and 2025 federal data.
- Why it matters: this gives the repo a retained reporting layer for ICE detention activity in Garfield County separate from the county jail dispute.
- Evidence layer: reporting based on federal datasets and FOIA-related material.
- Source basis: Garfield County ICE/DHS law-enforcement source cluster
- Colorado Times Recorder reports congressional demand-letter activity around ICE hold rooms and notes Rep. Joe Neguse's attempted oversight visit to an ICE holding room in Garfield County.

- Evidence layer: reporting on congressional letter and public official statement.
- Source basis: Garfield County ICE/DHS law-enforcement source cluster
- Glenwood Springs issues a notice of violation to JG Housing Solutions LLC concerning 100 Midland Avenue, Suites 110 and 210. The notice says the city found enough evidence to reasonably conclude the special use permit had been violated by detainee holds over the stated time limit.

- Source basis: Garfield County ICE/DHS law-enforcement source cluster
2026-04-28: Glenwood Springs' notice schedules a Planning and Zoning Commission hearing for the 100 Midland Avenue notice of violation. This hearing had not occurred as of the current task date, 2026-04-17.
- Several entries from 2024 and 2025 rely on excerpts embedded in the 2026 legal-demand packet. They should be upgraded only after original CORA productions are retained.
- The timeline should not be read as proof of continuous formal cooperation across all periods. It is a sequence of sourced events, statements, policies, allegations, and disputes.
- Municipal and county conduct remain distinct unless a source directly links them.
