We identified a number of serious issues that violate U.S. Immigration and Customs Enforcement’s (ICE) 2011 Performance-Based National Detention Standards and pose significant health and safety risks at the facility. Specifically, we are concerned about nooses in detainee cells, improper and overly restrictive segregation, and untimely and inadequate detainee medical care. We recommended that ICE conduct a full review and inspection of the Adelanto ICE Processing Center and the GEO Group’s management of the center to immediately to ensure compliance with ICE’s 2011 Performance-Based National Detention Standards. Specifically, ICE must review and ensure compliance with: Personal Care Required; Segregation; and Medical Care. We made one recommendation to improve conditions at the facility.
