The Governor may, in his discretion, surrender, upon demand of the executive authority of another state, any person found in this state, notwithstanding the fact that a criminal prosecution or charges under the laws of this state are pending against the person, that the person has already been convicted in this state and is serving a sentence in any jail or penal institution of this state or of any county or municipality thereof, or that the person is serving a suspended or probationary sentence. The Governor may condition the release of the prisoner to the demanding state upon such terms as he may stipulate, including the condition that the prisoner be returned to this state immediately after trial and before commencing the service of sentence, if any, in the demanding state. In no case shall surrender of the prisoner be construed as a complete relinquishment of jurisdiction by this state, but the prisoner shall forthwith be returned to the custody of this state at the expense of the demanding state immediately after trial in the demanding state or the completion of sentence therein, as the case may be, except where the sentence of death has been executed in the demanding state.
