The location here is the Barnes-Jewish Hospital where Robert Rayford checked himself in.
Robert Rayford (c. 1953 – May 15 or May 16,[2] 1969), sometimes identified as Robert R. due to his age, was an American teenager from Missouri who had the earliest confirmed case of HIV/AIDS in North America. His death baffled doctors, who could not account for Rayford's symptoms. The cause of his death was not identified until 1987.
