“Cole put a lot of care and detail into these pages, and it shows. His ear for the details surrounding the case is pitch perfect. Tune in if you’re ready for the case of a lifetime.”

Independent Book Review

This rigorously detailed book focuses on all of the unfortunate victims and the particulars leading up to their murders. Cole’s concise, unadorned prose lets the unnerving facts of the case speak for themselves. …it’s a wealth of information that will surely rouse interest in the analyses and speculations that will appear in the sequel.” – Kirkus Reviews

“The narrative includes abundant cultural contextualization—about the civil rights movement, the Vietnam War, and the movie The Exorcist—revealing the time period in which the serial killer was active well. This helps to make it more than just a rehashing of hard facts: Cole reveals a tangible moment in history. His writing is smart and objective; its only assumptions and analyses come from law enforcement officers and detectives. Sans sensationalism and speculation, this is an academic, accessible text.”

Foreword Clarion Reviews

Incredibly informative on the facts of the case, the possible explanations, and why investigators to this day still have not solved this cold case, any lover of true crime would thoroughly enjoy what this book has to offer.

San Francisco Book Review

“Cole’s descriptions of the lives and personalities of those who fell to this tragic fate serve to memorialize them, if not bring them back to life. Hence the service performed by the author’s book is great indeed.”
