Jefferson County Sheriff's Office

Jefferson County Sheriff’s Office serves the western Denver suburbs — Lakewood, Arvada, Golden, Wheat Ridge, and unincorporated Jefferson County — a population of about 580,000. Its representative Dean Davis served on the CISC Board of Directors, confirmed through January 2021 meeting minutes.

CISC — the Colorado Information Sharing Consortium — operates the LexisNexis PSDEX data warehouse for Colorado, handling data from 124 agencies across the state. Board membership means Jefferson County SO is one of the agencies governing that infrastructure. Colorado has VALE Act sanctuary protections statewide, but the CISC/PSDEX route passes through LexisNexis as a private intermediary, putting the data flow outside the reach of state sanctuary law.

Jefferson County SO runs the Jefferson County Jail, which connects to Colorado’s Appriss VINE system. Whether Colorado’s VINE contract includes a Risk Solutions clause — which in Cook County, Illinois allows Appriss to share jail booking data with LexisNexis — is an open question.

Jefferson County Sheriff's Office is a confirmed PSDEX contributor. The executed CISC Member Agency Addendum and Joinder, the AVCC XML data contribution instrument used by CISC member agencies, is on file and archived at DocumentCloud. The county initialed the addendum's national data sharing option, authorizing contribution of its records data to the full PSDEX network in addition to the CISC Data Warehouse, which the contract's own language describes as a PSDEX private container database provided by LexisNexis.
