Kidnapping generally refers to taking or transporting someone against their will. If the transportation crossed state lines, the crime can be prosecuted federally. Few attorneys handle these cases, and fewer still are former federal prosecutors who are now ready to stand by your side.
Excerpt of 18 USC 1201:
§ 1201. Kidnapping
(a) Whoever unlawfully seizes, confines, inveigles, decoys, kidnaps, abducts, or carries away and holds for ransom or reward or otherwise any person, except in the case of a minor by the parent thereof, when— (1) the person is willfully transported in interstate or foreign commerce, regardless of whether the person was alive when transported across a State boundary, or the offender travels in interstate or foreign commerce or uses the mail or any means, facility, or instrumentality of interstate or foreign commerce in committing or in furtherance of the commission of the offense; (2) any such act against the person is done within the special maritime and territorial jurisdiction of the United States; (3) any such act against the person is done within the special aircraft jurisdiction of the United States as defined in section 46501 of title 49; (4) the person is a foreign official, an internationally protected person, or an official guest as those terms are defined in section 1116 (b) of this title; or (5) the person is among those officers and employees described in section 1114 of this title and any such act against the person is done while the person is engaged in, or on account of, the performance of official duties, shall be punished by imprisonment for any term of years or for life and, if the death of any person results, shall be punished by death or life imprisonment.
(b) With respect to subsection (a)(1), above, the failure to release the victim within twenty-four hours after he shall have been unlawfully seized, confined, inveigled, decoyed, kidnapped, abducted, or carried away shall create a rebuttable presumption that such person has been transported in interstate or foreign commerce. Notwithstanding the preceding sentence, the fact that the presumption under this section has not yet taken effect does not preclude a Federal investigation of a possible violation of this section before the 24-hour period has ended.
(c) If two or more persons conspire to violate this section and one or more of such persons do any overt act to effect the object of the conspiracy, each shall be punished by imprisonment for any term of years or for life.
(d) Whoever attempts to violate subsection (a) shall be punished by imprisonment for not more than twenty years.
