Administrators at Idaho's prison agency knew since at least 2010 that private prison contractor Corrections Corporation of America was understaffing the state's largest prison in violation of the state contract.
Idaho Department of Corrections officials and CCA eventually came to an agreement about staffing levels, according to documents obtained by The Associated Press, but inmates and advocates continued to complain about inadequate staffing and its impact on safety.
The new details about the state's oversight come as Idaho State Police investigators look into allegations that CCA defrauded taxpayers by filing reports that showed vacant positions were fully staffed.
That investigation is expected to be completed soon. The probe was launched after an AP public records request publicly raised questions among officials about possible fraud at the CCA-run Idaho Correctional Center.
