Description

Intended for forensic scientists and students of the discipline, Forensic Interpretation of Glass Evidence provides the practicing forensic scientist with the necessary statistical tools and methodology to introduce forensic glass evidence into the laboratory. With free software available for downloading at the author's Web site, scientists can apply their own data and draw conclusions using principles practiced in the text.

This book contains an introductory chapter on glass evidence procedures and analysis before covering topics such as classical approaches to handling glass evidence, the application of Bayesian statistics to forensic science, and the use of histograms.

By presenting both the physical and chemical examinations performed on glass along with a recommended interpretation, the author allows readers the luxury of having all reference materials contained within a single book. Useful for case-working forensic scientists, this book is ideal for students of forensic science at both the undergraduate and graduate levels, as well anyone currently working in the field.

Reviews

"…an outstanding text for trace examiners who provide statistical analysis of their data, or for those who wish to learn statistical treatment of evidence. An excellent set of references at the end of the book provides a thorough literature study of glass for those with the appropriate resources."

- Virginia M. Maxwell, State of Connecticut Forensic Laboratory, Meriden

"Forensic Interpretation of Glass Evidence contains valuable information for the practising forensic glass examiner and should be included on any trace evidence bookshelf. Overall this book has made a good attempt at summarizing the scientific literature pertinent to forensic glass examination and has made a good first attempt at describing the interpretation of glass evidence in a Bayesian context."

-Mark Sandercock, M.Sc., RCMP Forensic Laboratory, Winnipeg, in Canadian Society of Forensic Science Journal
