The Iowa Board of Corrections has approved the hiring of two new prison wardens, including one at the Anamosa State Penitentiary where two staffers were killed in March. Incoming Anamosa warden Kristofer Karberg most recently worked for the South Dakota Department of Corrections. He was part of the team that reviewed the Anamosa prison after a correctional officer and a nurse were murdered.

The new Anamosa warden says he’ll be an observer in his first days on the job.

For the past nine years, Karberg has been the deputy director of a state prison in Springfield, South Dakota and, in the five years before that, he was the commander of external security at the U.S. Embassy in Kabul, Afghanistan.

Iowa Department of Corrections director Beth Skinner says things are gradually transitioning back to normal at the Anamosa prison.
