Query: An investigation that wouldn't go away.

Prostitutes were turning up murdered in the Spokane area and all the police seemed to be interessted in doing was "bagging and tagging" them. Fitzsimmons and Fuhrman were the ones who seemed to be pursing clues, talking to witnesses and keeping this case alive. The Spokane authorities didn't seem to be too interested in using the "old fashioned" method of solving crimes--footwork and interviewing, they were convinced that DNA would catch this killer. Fuhrman paints a fascinating story of a serial killer just screaming to be caught. Shame on Spokane authorities for not being able to see the forrest for the trees, and kudos to Mark and Mike for their hard work. If you happen to see the story of Robert Yates on the court tv show The System, do yourself a favor. Turn off the TV and read the book. Well written, fast paced. Furhman did a first-rate job with this book
