THE FORENSIC ANALYSIS COMPARISON AND EVALUATION OF FRICTION RIDGE SKIN IMPRESSIONSAn
accessible highly practical introduction to the ACE framework fingerprint examiners use to
analyse compare and evaluate friction ridge skin impressions.When friction ridge skin (the
skin on the undersides of the hands and feet) contacts a surface an impression of it may be
left behind. Impressions that are left inadvertently for example at a scene where a crime is
alleged to have been committed are known as 'marks'. Impressions taken intentionally from a
person for example as a result of their arrest are known as 'prints'.The Forensic Analysis
Comparison and Evaluation of Friction Ridge Skin Impressions offers step-by-step instruction to
examiners tasked with identifying people by the marks they leave behind. Assuming no previous
knowledge of the subject this easy-to-use guide breaks down the ACE (Analysis Comparison and
Evaluation) framework into 10 key questions that provide clear guidance on: establishing the
most evidentially valuable mark the type of details the mark may reveal the effects of
distortion how to determine which area of skin is most likely to have made the mark and
more.Author Dan Perkins draws upon his years of experience to equip fingerprint examiners with
the key skills needed to carry out the appropriate analysis comparison and evaluation of
friction ridge skin impressions. Presents a stepwise approach designed for both novice and more
experienced fingerprint examiners Discusses all aspects of ACE including the formation of
fingerprints documentation suitability and orientation Contains references to relevant
research real-world case studies and hundreds of impressions the reader can analyse and
compare Includes five detailed appendices covering fabrication transplantation and forgery
verification bias activity level propositions and errorsThe Forensic Analysis Comparison
and Evaluation of Friction Ridge Skin Impressions is an indispensable ACE 'checklist' for
trainees in the field of fingerprint comparison and identification qualified fingerprint
examiners and forensic science students.
