Kenneth RatcliffI did enjoy both classes that I signed up for - Perspectives in Expert Testimony and Principles of Death Investigation. Upon completion of the courses I emailed both Kelly Ayers and Samantha Neal to thank them for their enthusiasm, insight, and comprehensive coverage of the subject matter. In most areas of Law Enforcement a person with my years of service (30 years) is considered a "dinosaur or relic" and past the point of being interested or teachable in most if not all matters concerning the various aspects of Law Enforcement. While this belief has certainly been true with me as of late, I feel I owe a debt of gratitude to both Kelly Ayers and Samantha Neal as well as to WVU for providing courses related to my current assignment and for re-kindling my interest. I found both courses informative and challenging, and I believe that I took away valuable information that will be of use to me as I continue on the path that I started on three decades ago. While participating in both courses I realized that for the first time in 2-4 years that I will miss my job when I'm forced to retire in a little over 15 months. I again want to thank all involved for reaffirming that the career choice I made so many years ago, was the right one.
