The court of appeals affirmed convictions on two counts of aggravated sexual abuse of a child, reversed the conviction on a third count, vacated the sentence imposed by the district court, and remanded. The court held that the district court properly denied appellant’s motion to suppress his confession on the ground that he was never given his Miranda rights, where appellant, who was not told that he was under arrest and was never restrained in any way, was not in custody for Miranda purposes. The court rejected the contention that an alleged threat of a polygraph transformed his non-custodial interrogation into a custodial one. The court reversed the conviction on one count because there was insufficient evidence to corroborate the corpus delicti of the act to which the defendant confessed on that count.
