P.R. Laws tit. 34, § 1881b
No demand for the extradition of a person charged with crime in another state shall be recognized by the Governor unless in writing alleging, except in cases arising under § 1881e of this title, that the accused was present in the demanding state at the time of the commission of the alleged crime, and that thereafter he fled from the state; and unless the demand is accompanied by a copy of the indictment or of the information supported by affidavit made in the state having jurisdiction of the offense, or by a copy of an affidavit made before a magistrate of said state, together with a copy of any warrant of arrest or commitment issued thereupon; or by a copy of a judgment of conviction or of a sentence imposed in execution thereof, together with a statement by the executive authority of the demanding state that the person claimed has escaped from confinement or has broken the terms of his bail, probation, or parole. 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.
