The infamous murder of Kitty Genovese murder in March of 1964 in front of dozens of passive bystanders stimulated research by social psychologists John Darley and Bibb Latane to investigate the theory of "diffusion of responsibility." Darley and Latane's research showed that the larger the number of bystanders, the less likely any one person is to help. However, the true Genovese story didn't play out quite as described in most intro psych books. In fact, many people tried to help and were unable to due to the fact that the deadly assault did not take place right in front of them. Although there still is validity to the bystander effect, its origins in this case are more mythical than real.
