The language of the kidnapping statute, along with the case law construing that language, must be read in a sensible manner and not taken to an illogical conclusion. Holding a victim in captivity for a period of four to five hours, while assaulting and sexually abusing her, satisfies the “substantial period” requirement of the kidnapping statute -- even if the length of the confinement is co-extensive with the continuous sexual and physical abuse of the victim. In addition, the Court cannot find that, as a matter of law, the terrifying four-to-five-hour period of C.M.’s confinement was “merely incidental” to the sexual violence committed against her. There is no basis to disturb the jury’s verdict.
