On June 20, 1947, one of the most notorious gangsters of the twentieth century, Benjamin "Bugsy" Siegel, was murdered in the Beverly Hills mansion of his mistress, Virginia Hill.

MacDonald's father, Archibald, was the right-hand man of billionaire Howard Hughes, Jr., while Betty Ann's mother, Gaynell Rockwell-Applegate, was a woman of "new money".
