The warden of the privately-run Idaho Correctional Center has quit, one month after his company acknowledged falsifying staffing records for much of 2012.
Timothy Wengler, who works for Corrections Corporation of America, lasted three years as warden of the prison south of Boise.
The Nashville, Tenn.-based company with the contract to run the prison through 2014 says Wengler's last day is May 31.
CCA spokesman Steve Owen says Wengler had been thinking about quitting for a year and described his departure as a "personal decision."
Wengler was supposed to help repair problems at the prison.
He arrived in Idaho in 2010, a replacement for a previous warden the company removed after the American Civil Liberties Union sued over claims of brutal inmate-on-inmate violence.
CCA says it's mulling Wengler's replacement now.
