As a veteran staff member of the Arizona Department of Corrections, I am seeking information related to the Polygraph examiners assigned to our Professional Standards Bureau. I currently have subordinate staff that are having examinations administered to them as part of internal investigations. I am also aware that several recent issues have been raised by other supervisors as to the professional standards and testing methods that are utilized by our examiners. Given that the staff who have raised these concerns are very credible in my opinion, I have begun my own research into this issue. The examiners that are specifically in question are Roger McFarlin, Helen Moody, Gary Lindburg, and Peter Clark. It is my understanding that Roger McFarlin has been with our agency for several years and came to us from the US Army Criminal Investigations Division. The other three examiners appear to be new to our agency and there is little background available in regard to their history as examiners. If anyone has any information, pro or con, available regarding these examiners, specifically Roger McFarlin, please drop me an e-mail at the e-address listed with my account. In addition, if anyone is aware of any other individuals who may be able to assist me in this research, please pass that along to me as well, along with some contact point. Thank you all for your assistance in this matter.
