Dear Mr. Scott,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Subject Index to General and Formerly Confidential Correspondence, 1917 - 1954 which is an index to the General Correspondence, 1917 - 1947 in the Records of the Office of the Inspector General (Army) (Record Group 159) that may include a file if an investigation was held at the Army level. Otherwise, the investigation may have been conducted by the unit. For more information about these records, please contact the National Archives at College Park - Textual Reference (RDT2) at firstname.lastname@example.org.
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 RDT2. We apologize for this inconvenience and appreciate your understanding and patience.
We also searched the internet and located a picture of a small newspaper article at the California Digital Newspaper Collection, which is a project of the Center for Bibliographical Studies and Research (CBSR) at the University of California, Riverside. There is a longer article that explains what happened from Architect of the Capital, Hidden History in Washington, D.C.
We hope this is helpful. Best of luck with your research!
