When a crime or other incident takes place, clothing items are often present or left behind, and can become directly involved in the case itself. Items of clothing are thus one of the most common types of exhibit examined in court. They can provide valuable information in cases of violent crimes, such as homicide or rape, as well as in burglary, robbery, arson, and vehicular accidents.
A unique reference in the forensic arena
The first of its kind, Scientific Protocols for Forensic Examination of Clothing discusses the forensic examination of clothing in criminal cases. It examines the ramifications of DNA profiling and its effect on the screening approach to clothing examination. Coverage includes protocols and procedures, preliminary assessment, examination, testing and sampling, quality assurance and control, and the significance of results.
Applicable to a myriad of readers
Suitable for a wide range of readers, this book is designed for examiners trying to decide how to approach a clothing examination, those looking for more information on a specific topic, laboratory quality assurance officers in need of a reliable reference, as well as attorneys, investigators, archaeologists, and curators.
Author Jane Moira Taupin has testified as a forensic expert more than 130 times. Chesterene Cwiklik is a founder of the Pacific Coast Forensic Science Institute. Their expertise makes this a valuable resource for all those who examine clothing items and interpret subsequent findings.
An interesting feature of this text is the practical exercises at the end of each chapter encouraging the reader to apply the various principles under discussion, and to visit local good and bad examples of green chemistry.

"The science is supported by excellent illustrations and case studies. Each chapter is well-referenced for further study. … essential for the proper understanding and preparation of that special case."
—Law Society Journal
"The authors are experienced forensic scientists with different perspectives; their experiences combine to provide useful suggestions for the practitioner responsible for the forensic examination of clothing. The forensic scientist assigned to examine clothing for physical evidence would benefit greatly from a full understanding of the suggestions in this book. More importantly, stakeholders (investigator, litigator, and trier of fact) will benefit from clothing examinations conducted in the ways described in this book."
— Richard E. Bisbing, in American Academy of Forensic Sciences
" … provides a very good starting point for readers that have no or limited exposure to the field. I would recommend this book to any forensic examiner understudy … "
—Ghislain Cormier, National Operations Specialist, RCMP Forensic Investigations Support Services, Ottawa, Ontario"This is a practical and useful book … more than meets the hopes of the authors. It should be essential reading for all forensic scientists to remind them tht the forensic process is holistic and not about single evidence types."
—James Robertson, Australian Journal of Forensic Sciences
