Today we revisit a conversation from August, 2014 with Jeff Guinn, author of "Manson: The Life and Times of Charles Manson" says he wanted to answer two questions with the book: "Why does Manson's name still resonate with us, all these years after those famous murders? And what happened in his life to make him the way he turned out?" Guinn says that in answering those questions "it was really like a trip across American history because Manson represents so many aspects of American society." More than 40 years ago Charles Manson and his mostly female commune killed nine people, among them the pregnant actress Sharon Tate.
