BOISE, Idaho (AP) — The warden of the privately run Idaho Correctional Center has quit a month after the company acknowledged that his employees falsified thousands of hours of staffing records during much of 2012.

Timothy Wengler, who works for Corrections Corporation of America, lasted just three years as warden of the prison south of Boise. His last day will be May 31, according to the Nashville, Tenn.-based company that has a contract to run the prison.
