Marcel D. Elfers

My name is Marcel Elfers and I am a master profiler through written communication and forensic document examiner. I use handwriting analysis, statement analysis, and behavioral trend analysis to come to an author profile.

My first book "we are the same, it's the details that differ" shows 9 distinct behavioral patterns within the realm of criminal cases. The JonBenét Ramsey, Elliot Rodger, and George Zimmerman cases are reviewed and explained in detail within their respective behavioral patterns. The JonBenét case has haunted us for many years. I studied the case at length and after 10 years finally put my findings down in book form.

My favorite book is "One Reason" which is also about the 9 distinct behavioral patterns but is simplified focusing on readers without a profiling background. It is an Enneagram introduction describing the structure, basic patterns, and the motivation behind them.

I am also an avid pool player and enjoyed writing two books about pocket pool principles. The Banking and Kicking instructional book is to the point without having to sit through 14 hours of video online.
