A demand for the extradition of a person wanted in another state shall not be recognized by the governor unless the demand is in writing and states the purpose for which he is wanted. The demand must be accompanied by:
The indictment, information, or affidavit made before the magistrate must substantially charge the person demanded with having committed a crime under the law of that state; and the copy of the indictment, information, affidavit, judgment of conviction, or sentence must be authenticated by the executive authority making the demand.
