None was more affected by the story than her younger brother, Bill. He vowed to reject apathy and try to make a difference in the world. The Witness begins in 2004 when the New York Times questioned its original story, including the number of witnesses, what they observed and the number of attacks. What if Kitty's mythic story is an urban myth? Breaking his family's half-century of silence, Bill seeks to find the truth with a probing and deeply personal investigation into one of the most iconic crimes in New York history, offering an illuminating look into the way stories take form and their rippling effects on the lives they touch.
