Over 38 people over the course of 30 minutes watched as her attacker returned again twice and stabbed her, the third time being a fatal wound. (Source 1) Kitty Genovese died after nearly 40 people had witnessed the attacks and failed to contact the police.

Participants who knew that other observant could report the emergency felt less responsible and reported the incident more slowly than participants who were the only observant to the scene.
