In kidnapping, the seizure and detention must be involuntary and consent by the victim establishes a defense to kidnapping. United States v. Sellers, 62 Fed. Appx. 499, 502 (4th Cir. S.C. 2003). In addition, if the defendant was a relative of the victim and his sole purpose was to assume custody of the victim, then that itself constitutes a valid defense to the kidnapping charge. United States v. Landham, 251 F.3d 1072, 1081 (6th Cir. Ky. 2001).
