Overview

Arapahoe County (FIPS 08005, heatmap score 64) hosts Colorado’s busiest secret ICE hold room (DENHOLD in Centennial) and shares the Aurora ICE Processing Center with Adams County (the facility address is in Adams County, but Aurora itself straddles the county line — the city’s population of 400,000+ is divided between Arapahoe and Adams counties). Arapahoe County had the third-highest ICE arrest count in Colorado in 2025, behind only Denver and El Paso counties.

The DENHOLD Hold Room (Centennial)

The DENHOLD hold room at ICE’s Denver field office (12445 E. Caley Ave, Centennial) was exposed by the Colorado Times Recorder in March 2026 as the busiest of nine secret ICE hold rooms in Colorado. Nearly 1,400 detainees passed through between January 20 and October 2025. See separate facility entry: centennial-denhold-ice-hold-room-co.

Key facts:

• Bedless facility where people were held for up to 39 days (vs. 72-hour rule)
• 39 children aged 9 or younger detained, youngest a 1-year-old girl
• Building owned by NGP Group (Virginia), charging $2.2M/year in federal rent
• Invisible in heatmap data — no IGSA, no published contracts

Aurora City Council MOU Debate (April 2026)

The city of Aurora — which straddles Adams and Arapahoe counties — is debating a 10-year MOU governing police response to the GEO Group ICE facility. This fight directly affects Arapahoe County residents:

• Background: Two detainees escaped during a March 18, 2025 power outage. ICE blamed Aurora police for delayed response; police said ICE didn’t notify them for hours.
• April 7, 2026: Council voted 10-1 to postpone the MOU vote (Stephanie Hancock sole dissent) for at least two weeks
• MOU provisions: Aurora police would respond to criminal incidents at the facility but with “explicit guardrails” against immigration enforcement
• Opposition: Activist Jeffrey McFarland called it “a 10-year partnership between a local police department and a federal agency tearing families apart”
• January 12, 2026: Council had previously passed a resolution 6-4 declaring opposition to “ICE overreach”

Sheriff Tyler Brown’s Position

Arapahoe County Sheriff Tyler Brown (elected 2022) has taken a cautious middle position:

• Discussed ICE cooperation in an August 2025 radio interview but did not publicly commit to closer cooperation
• The Sheriff’s Office stated it had “no evidence that any employee leaked information related to ICE operations” after ICE Director Todd Lyons accused local law enforcement of leaking raid details
• Arapahoe County does not track how many times it notifies ICE before releasing inmates
• Colorado’s sanctuary law prohibits the county from holding people solely on ICE detainers

ICE Arrest Surge (2025)

Arapahoe County was ranked third statewide for ICE arrests in 2025 (behind Denver at 1,548 and El Paso County). Exact county-level numbers were not published, but ICE agents targeted residences in Aurora and Arapahoe County in coordinated February 2025 raids. The statewide total reached 3,522 arrests from Jan 20–Oct 15, 2025 (vs. 843 in same period 2024).

Colorado Legal Context

Colorado’s sanctuary framework constrains what Arapahoe County can do:

• 2019 law: Prohibits arrest/detention based solely on ICE requests
• 2017 Denver ordinance: Additional restrictions (Denver borders Arapahoe)
• Only Teller County has a 287(g) agreement statewide; El Paso County was applying for one as of March 2025
• The 2019 Arapahoe County case — an unauthorized Cuban immigrant released from the county jail later accused of attempted murder (charges dismissed) — remains a political flashpoint

Why This Matters

Arapahoe County’s heatmap score of 64 (igsa:4, anc-contract:3) only captures the formal contract signals. The DENHOLD hold room adds an entirely invisible shadow detention layer processing nearly 1,400 people per year through a bedless facility in an office building. Combined with Arapahoe’s role as the third-highest county for ICE arrests and the ongoing Aurora MOU debate, this county is a critical node in Colorado’s detention infrastructure.
