BOISE, Idaho (AP) — The Idaho Attorney General's office is calling for a criminal investigation into Correction Corporation of America's understaffing of the Idaho Correctional Center after learning that a police investigation announced last year was never done. Attorney General Lawrence Wasden wrote the letter to Idaho Gov. C. L. "Butch" Otter and the heads of the State Police, Department of Correction and the Ada County Prosecutor's Office on Friday. The Associated Press obtained the letter through a public records request. In it, Wasden said there appears to be a large degree of confusion with regard to whether a criminal investigation into CCA's operations at the Idaho prison should be conducted. Wasden said that to ensure no confusion going forward, he is recommending that a criminal investigation begin immediately.
