LINCOLN, Neb. (AP) — A Nebraska corrections official who was criticized by lawmakers in a state prisons investigation is set to retire.

Larry Wayne, the deputy director of Nebraska’s Department of Correctional Services, will step down effective April 3. The department’s new director, Scott Frakes, announced the retirement on Monday.

Some lawmakers blamed Wayne for the state’s handling of Nikko Jenkins, an inmate who was released despite claims of mental illness and who went on to kill four people in Omaha. A state ombudsman told lawmakers that Wayne had promised to “bury” Jenkins in segregation, which Wayne denies.

Wayne has served in the role since April 2003, and his career in the department stretches back to August 1975. He served in roles including warden, administrator, investigator, unit manager, senior case manager and classification counselor.
