* I made multiple attempts to find Barbara C. The Culinary Workers Union, which covers cocktail waitresses, had only one listing in its 1969 and 1970 archives that matched her name. But when I reached the woman, she said she’d never met Sonny and didn’t know another cocktail waitress who shared her name. Police records, database searches, and old phone records were also unavailing. If she’s still alive, she is as elusive today as she seemed to be then.
