Dear Ms. Wilson,
Thank you for posting your request to History Hub!
We searched the National Archives Catalog and located the series Inmate Case Files, 7/3/1895-11/5/1957 in the Records of the Bureau of Prisons (Record Group 129) that contains case files of prisoners held at Leavenworth. These records have been digitized and can be viewed online via the Catalog. Please contact the National Archives at Kansas City (RM-KC) at email@example.com with any questions you may have about these records.
Next, we located the series Subject Files, ca. 1906 - 10/3/1989 in Record Group 129 that includes records from the U.S. Penitentiary, Leavenworth that may be of interest to you. This series does not include case files for each inmate, but it may contain references to some of the inmates. These records have not been digitized. For access to and information about these records, please contact RM-KC.
You also may wish to review other records related to the Bureau of Prison's U.S. Penitentiary, Leavenworth in the Catalog.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RM-KC. We apologize for this inconvenience and appreciate your understanding and patience.
Finally, USP Leavenworth records contain information about federal inmates released AFTER 1982. USP Leavenworth received many requests for information on Federal inmates released before 1982. Not all inmates who were in custody prior to 1982 were keyed into the BOP's inmate management system. Accordingly, when FCI Leavenworth previously received a request for such information, USP Leavenworth researched available records by hand. Many older records are held by the National Archives Records Administration (NARA), not the BOP and are in the midst of transferring BOP's pre-1982 inmate records to NARA. Please contact Lindsey George, Records Manager, Bureau of Prisons (BOP), 400 First Street, NW - Room 6009, Washington DC 20534 via LEIza@bop.gov for location of the inmate records from USP Leavenworth for November 1957-1981.
We hope this information is helpful. Best of luck with your family research!
