The trial court erred by convicting the defendant of both first-degree kidnapping and the sexual assault that raised the kidnapping to first-degree. The trial court instructed the jury that to convict defendant of first-degree kidnapping, it had to find that the victim was not released in a safe place, had been sexually assaulted, or had been seriously injured. The jury returned guilty verdicts for both first-degree kidnapping and second-degree sexual offense but did not specify the factor that elevated kidnapping to first-degree. The court concluded that it must construe the ambiguous verdict in favor of the defendant and assume that the jury relied on the sexual assault in finding the defendant guilty of first-degree kidnapping.
