OMAHA, Neb. (AP) — The Nebraska Department of Correctional Services says that of 390 prisoners who have or will be released between June 10 and Aug. 31, more than two dozen had miscalculated release dates. Prisons director Scott Frakes said Friday that of the 29 miscalculations, 23 had been given so-called "good time" credit they should not have received and saw their sentences lengthened.
