"Yvonne Mason has captured the true essence of Gerard Schaefer, a deputy sheriff who

enjoyed torturing and killing young women. It is a gripping story and you should prepare to be

disturbed. I guarantee that you will find it difficult to put this book down."

Roy Hazelwood, FBI (ret)

author of Dark Dreams and

The Evil That Men Do

When Gerald Schaefer used his badge and gun to terrorize and kill rather than protect and serve he crossed a line that not only snuffed out the lives of his victims but also affected the lives of their loved ones and the police officers charged with investigating these crimes. In her book "Silent Scream" Yvonne Mason has captured more than just the story, but has also given voices to all of Schafer's unknown victims. I'm sure there are many.

Det. Lieutenant Chuck Hemp OPPD Ret.

Silent Scream is one of the most compelling and frightening manuscripts I've ever read! The terror and madness of Schaefer will continue to tug at your psyche all the way through the book.

Yvonne Mason speaks with a profound literary voice for Schaefer's victims. Here, they are silent no longer.

No, I won't sleep well, just knowing that another Schaefer may be out there somewhere. I pray not.

Well done, Yvonne!
