Dear Mr. Johnson,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located a series titled Records Relating to Key Persons, 11/30/1963 - 9/24/1964 in the Records of the President's Commission on the Assassination of President Kennedy (Record Group 272) that includes a file unit titled Adams, Vickie. The file unit has been digitized and is available for viewing using the Catalog. Vickie Adams is the only witness with the first name Vickie or Victoria in the records.
We hope this information is helpful. Best of luck with your research!
Thank you for this reply. Vicki's last name was not Adams. Her name at the time, her maiden name, was Vicki Joe Shing. (Vickie Adams is a well known witness, and even the subject of a book by Barry Ernest, but she is not the Vicki in question.)
