MORE ABOUT LES PEACE:
Les was a regular member of the Royal Canadian Mounted Police for 24 ½ years, including 20 years as a Forensic Document Examiner in the RCMP Laboratories at Vancouver (British Columbia), Edmonton (Alberta), and Regina (Saskatchewan). He retired in 1988 with the rank of Staff-Sergeant, and immediately commenced private practise in Lethbridge to serve a very broad range of clients from Ontario to British Columbia to the NorthWest Territories.
His combined experience in public and private practise now exceeds 36 years, and during this lengthy period of time Les has personally completed more than three thousand case files. Many of these files have required detailed and complex examinations of numerous forged and fraudulent documents, followed by competent and capable expert testimony at all levels of Court in the provinces of Manitoba, Saskatchewan, and Alberta.
Les has completed many case-related but unpublished research studies of inks, forgery, disguise, charred documents, mail tampering, sequence determinations, physical matching, handwriting analysis, and alcohol-induced writing variations. In 1983, he also completed a formal research proposal entitled The Examination of Torn and Perforated Documents, which was subsequently published by the Canadian Society of Forensic Science. Les has also assisted various colleagues in the formal study of photocopier identification techniques, the examination and comparison of handwriting produced by identical twins, and the evaluation of effective solvent systems for ink chromatography.
As a senior RCMP examiner from 1982 - 1988, he co-authored several modules of the Course Training Standard then utilized by understudies in the R.C.M.P. Forensic Laboratories, and developed a comprehensive set of experiments to guide and evaluate candidates during the Forgery and Disguise modules of their training. At least seven serving or retired RCMP document examiners have received some or all of their formal training under Les' guidance and supervision.
Throughout his lengthy career in Forensic Document Examination, Les has presented numerous formal and informal talks or seminars to various police, legal, corporate, and community groups. He continues to develop a broader set of professional skills by participating in Graphic Arts and Digital Imaging courses at the Lethbridge Community College, together with Fraud Investigation courses at the University of Calgary.
As an active partner in Q.D.I., his knowledge and considerable experience are now available to clients who require his assistance with on-site search, seizure, or evaluation of fraudulent documents. And of course, his expertise is routinely applied to a wide variety of document examination problems submitted to our modern office facility in Lethbridge.
