Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
The most in depth investigation into Israel Keyes ever published. With information drawn from many hours of FBI interviews & with access to Law Enforcement files, this is a great read & insight into his life & crimes. While there is much we still don’t know about his victims, his character & M.O is laid bare in this book. Would recommend for fans of true crime.
