 According to federal prosecutors, the private corrections company — unidentified in the court documents but widely believed to be Cornell Companies — was not implicated in the plot, and had been unaware of the FBI investigation until Anderson's indictment and arrest.The confidential informant in the case was Frank Prewitt, a former commissioner of the Alaska Department of Corrections who took a job with Cornell Companies after it purchased Allvest.Two of the early private prisons venture partners were caught up in the ongoing Alaska political corruption probe leading to blogger and press speculation that Prewitt's service to the federal government may have been the result of a secret plea agreement although no formal charges were placed.
