Section 570.30. Confinement of extradited persons passing through this state

The  officer or agent of a demanding state to whom a prisoner may have
  been delivered following extradition proceedings in another state, or to
  whom a prisoner may have been delivered  after  waiving  extradition  in
  such  other  state,  and  who  is passing through this state with such a
  prisoner for the purpose of immediately returning such prisoner  to  the
  demanding state may, when necessary, confine the prisoner in the jail of
  any  county  or  city  through which he may pass; and the keeper of such
  jail must receive and safely keep the  prisoner  until  the  officer  or
  agent  having  charge  of  him  is  ready  to proceed on his route, such
  officer or agent, however, being chargeable with the expense of keeping,
  provided, however, that such officer or agent shall produce and show  to
  the  keeper  of such jail satisfactory written evidence of the fact that
  he is actually transporting such prisoner to the demanding state after a
  requisition by the executive authority of such demanding state or waiver
  thereof.  Such person shall not be entitled to demand a new  requisition
  while in this state.
