Context: Institutional Pattern #

The Ramirez sexual assaults (August-September 2024) occurred in a facility without PREA compliance mechanisms or institutional corrections. This failure to implement safeguards after the Ramirez incidents became evident 16 months later when another inmate was injured by jail staff, demonstrating the lack of corrective action by Colorado County.

The Colorado County Jail operated without PREA (Prison Rape Elimination Act) policy, PREA Coordinator, or PREA training during all documented incidents, despite receiving $4.2M+ in federal State and Local Fiscal Recovery Funds (Award ID SLFRP4543) designated for “Jail Rehabilitation.”

Case Status #

Status: Open and Active

Approving Officers: Alisha Chiles, Jeffrey Wolf (TRD Company A Bryan)

Documents #

This investigation documents a pattern of institutional failure to protect persons in custody. The Colorado County Jail’s lack of PREA compliance, absence of supervision protocols, and failure to implement corrective measures following prior incidents created conditions where law enforcement personnel could commit sexual assault with minimal oversight.
