What real criminal case inspired Lloyd Bacon's film Marked Woman?

Lloyd Bacon's 1937 film Marked Woman was inspired by the real-life criminal case of Lucky Luciano.1

In 1936, Luciano, a powerful figure in organized crime, was tried and convicted for his role in a massive prostitution and extortion racket after several women involved in his operations testified against him. The film mirrors these events, featuring a nightclub hostess who agrees to testify against a mob boss following the death of her sister, with the character of the prosecuting attorney modeled after the real-life special prosecutor Thomas E. Dewey.21
