[1] The petitioner-appellant, Diana Schneckloth, appeals the Jefferson County district court's discharge of her petition for a writ of habeas corpus. The district court discharged the writ because the warrant and supporting documents sufficiently charged the petitioner with committing forgery in Nebraska and failing to appear for sentencing after conviction of forgery. On appeal, the petitioner claims that extradition should be denied because the district court failed to make a specific finding as to the credibility of the person who signed the affidavit in support of the extradition demand. We affirm the district court's discharge of the petition.
[2] The petitioner was convicted of second degree forgery in Nebraska on March 11, 1980. When she failed to appear for sentencing, a warrant was issued for her arrest. The Jefferson County sheriff arrested the petitioner on August 12, 1981. Colorado authorities served her with the governor's warrant on October 5, 1981. At the hearing on her petition for a writ of habeas corpus, the petitioner argued that the extradition documents failed to establish probable cause to support the charge against her. The petitioner contended that because there was no proof of the credibility of the affiant in this case, a writ of habeas corpus should be issued. The district court found the documents sufficient and denied the petition.
[3] The petitioner renews her argument in this appeal. She cites no authority for her contention that, when ruling on a petition for habeas corpus in an extradition case, a district court specifically must find that the signer of the supporting affidavit was credible.1
[4] Section 16-19-104, C.R.S. 1973 (1978 Repl. Vol. 8)2 requires that a demand for extradition be accompanied by "information supported by affidavit in the state having jurisdiction of the crime." The statute imposes no obligation that the affiant be proven credible. The requisition documents submitted in this case included the information charging the petitioner with second-degree forgery and the affidavit of the deputy county attorney of Douglas County, Nebraska, sworn before a judge of the district court for that county. The *Page 1295 challenged affidavit satisfies the requirements of section 16-19-104. Read together, all of the documents substantially charge the petitioner with a crime in Nebraska. See Lucero v. Martin, 660 P.2d 902 (1983). No finding in the asylum state as to the affiant's credibility is necessary.3 An attack on credibility is, in effect, an attack on the demanding state's finding of probable cause. Such an attack is possible only in the courts of the demanding state. Michigan v. Doran, 439 U.S. 282 (1978). Lucero v. Martin, supra. Once a court in the asylum state has satisfied itself with the facial validity of the documents, no further inquiry is appropriate on this issue. Steinman v. Caldwell, 628 P.2d 110 (Colo. 1981). Therefore, the district court properly denied the petition for habeas corpus.
[5] Judgment affirmed.
