Jeff Guinn is a former award-winning investigative journalist and the bestselling author of numerous books of fiction and nonfiction, including a biography of Bonnie and Clyde. His latest book is a new account of the life and times of Charles Manson. Going back to Manson's childhood, Mr Guinn interviewed Manson's sister and cousin, neither of whom had ever previously cooperated with an author. Childhood friends, cellmates, and even some members of the Manson family have provided new information about Manson's life. Jeff Guinn has made discoveries about the night of the Tate murders, and places Manson in the context of the turbulent late sixties. His book, Manson: The Life and Times of Charles Manson, is published by Simon and Schuster.
