Okla. Stat. tit. 22, § 22-1141.3: Requisites of demand - Accompanying papers

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 Section 6, 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

accompanied by a copy of an indictment found or by information

supported by affidavit in the state having jurisdiction of the

crime, or by a copy of an affidavit made before a magistrate there,

together with a copy of any warrant which was 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

indictment, information, affidavit, judgment of conviction or

sentence must be authenticated by the executive authority making the

demand.
