In an appeal from a juvenile defendant's sentence for violating the terms of his supervised release, the district court's requirement that defendant register as a sex offender under the Sex Offender Registration and Notification Act (SORNA) is reversed where the retroactive application of SORNA's provision covering individuals who were adjudicated juvenile delinquents because of the commission of certain sex offenses before SORNA's passage violated the Ex Post Facto Clause.
