A former state official says Nebraska's corrections department had no clear guidance on how to calculate prison sentences after he retired in 2008, and the job was left to a records clerk who shouldn't have been responsible for the task.

Ron Riethmuller, a former records administrator, told lawmakers Thursday that hundreds of inmate sentences were miscalculated because many employees were confused about the proper procedures.

Riethmuller says the state records administrator should have been responsible for calculating the sentences, but the job was given to a now-retired clerk, Jeannene Douglass.

Kyle Poppert, the current records administrator, was suspended for two weeks without pay.  Riethmuller's remarks came during a special hearing convened by lawmakers who are trying to find out why hundreds of inmates were released too early.
