About the disturbance:
Around 6:18 p.m., inmates at the medium-custody Cheyenne Unit attacked prison personnel. Inmates threw rocks, set fires to mattresses and other property outside on the yard, and broke into the prison health unit. Approximately 600 of the unit’s 1,147 inmate population were involved in the disturbance.
By 9:00 p.m., ADC’s quick response and tactical teams had brought the disturbance under control. All employees were verified to be safe and accounted for.
The inmates involved were contained and remained on the fenced recreation yard overnight as ADC personnel began conducting assessments and processing inmates.
The department is thoroughly investigating all facets of the disturbance, including possible motivation of the inmates. ADC will seek additional criminal charges for any inmates involved in this violent activity.
