In the beginning I was very skeptical as I began listening to this book, and at first I found it very looong, and thought why those mentions of all those other cases. However now I’ve finished the book, I’m speach less due to all the investigations this author has done. I’m convinced the killer was the father of this gentleman who is the author of this ok. Actually I can’t get enough of his research – I love to learn more. I highly recommend this book
