Section 105.25. Conspiracy; jurisdiction and venue

1. A person may be prosecuted for conspiracy in the county in which he
  entered  into  such conspiracy or in any county in which an overt act in
  furtherance thereof was committed.
    2. An agreement made within this state  to  engage  in  or  cause  the
  performance of conduct in another jurisdiction is punishable herein as a
  conspiracy  only  when  such conduct would constitute a crime both under
  the laws of this state if performed herein and under  the  laws  of  the
  other jurisdiction if performed therein.
    3. An agreement made in another jurisdiction to engage in or cause the
  performance of conduct within this state, which would constitute a crime
  herein,  is  punishable  herein only when an overt act in furtherance of
  such  conspiracy  is   committed   within   this   state.   Under   such
  circumstances, it is no defense to a prosecution for conspiracy that the
  conduct  which is the objective of the conspiracy would not constitute a
  crime under the laws of the other jurisdiction if performed therein.
