Arapahoe County Sheriff's Office

Arapahoe County Sheriff’s Office serves the south Denver metro — Aurora, Englewood, Centennial, Littleton, and unincorporated Arapahoe County — a population of about 650,000. Its representative Jared Rowlison served on the CISC Board of Directors, and the meeting minutes note he seconded the motion to approve N-DEx access codes — a detail that places him as an active participant in the governance of Colorado’s law enforcement data infrastructure.

CISC — the Colorado Information Sharing Consortium — operates the LexisNexis PSDEX data warehouse for the state, confirmed directly by CISC’s Executive Director. Arapahoe County SO runs the Arapahoe County Detention Facility, which connects to Colorado’s Appriss VINE system. Whether that VINE contract contains a Risk Solutions clause — allowing booking data to flow to LexisNexis separately from the PSDEX pipeline — is an open question under investigation.

Arapahoe County has no sanctuary protections. Aurora, the largest city in the county, was the site of high-profile federal immigration enforcement actions in 2025.
