Dear Ms. Wanke,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located two series titled Criminal Case Dockets, 1912 - 1986 and Criminal Case Files, 1912 - 2004 in the Records of District Courts of the United States (Record Group 21) that may have the case in which you are interested, assuming it was tried in the U.S. District Court for the Phoenix Division of the District of Arizona. For access to these series, please contact the National Archives at Riverside (RW-RS) via email at firstname.lastname@example.org and provide RW-RS with the case number.
If you are unsure which court tried the case, we suggest that you search the Arizona Court Case Finder to determine the court.
We hope this is helpful. Best of luck with your research!
