In Nebraska the law requires almost all cases filed be filed in juvenile court if the offender is under age 18. it is very difficult for a prosecutor to get a case in adult court unless it is murder, rape or the offender has a serious criminal history. Senator Brad Ashford got this passed in 2013. I have seen very few cases filed in adult court since that time. I do not know the circumstances in the case above. The parents very well could have used connections.
