Few forensic materials give rise to such differing views on their value as evidence, and these views are often held with a passion. Some believe that hairs provide worthless evidence, while others believe that hairs can provide potentially, and actually, very significant evidence. The application of DNA methods to the examination of hairs has sparked renewed interest in the forensic examination of hairs and the role of microscopic examination. As editor of this volume, I make no excuse for being a believer in the value of hair examination. However, the purpose of this book is not to take an evangelical stand to persuade the non-believers. The content should provide the balanced reader with enough factual information to enable him/her to form his/her own view. Chapters deal with the physiology and growth of hair, the microscopic examination of hair, the use of DNA analysis, forensic examination for cosmetic treatments, drugs and elemental analysis, and an assessment of the evidential value and interpretation of hairs as evidence. In the final analysis, it is for each laboratory system to decide on its own strategy and policy with regard to hair examination. What should be abundantly clear to the reader is that half-hearted commitment to the forensic examination of hairs is dangerous. Laboratory managers and leaders need to decide whether or not they are in a position to make a full commitment. There is also undoubtedly the need for more quality assurance measures, including proficiency testing to ensure the scientific reliability of hair examination. I thank my authors for their great patience in what turned out to be a very lengthy process. I thank my wife, Margaret, for help with editorial and wordprocessing input. I am glad to report that our marriage has now survived three books! Finally, this book is dedicated to my parents, John and Jeanetta Robertson. James Robertson Canberra Notes on Contributors Bruce Budowle FBI Laboratory, Forensic Science Research and Training Center, FBI Academy, Quantico, Virginia 22135, USA Bruce received a PhD in Genetics from Virginia Polytechnic Institute and State University, Blacksburg, Virginia in 1979. Subsequently he was awarded a Postdoctoral Fellowship in Immunogenetics by the National Cancer Institute and carried out research at the University of Alabama in Birmingham on genetic risk factors for insulin-dependent diabetes, melanoma and acute lymphocytic leukemia. In 1983 he joined the FBI to develop genetic marker systems for forensic human identity testing. His current position at the FBI is Program Manager for DNA Research. Bruce has published over 200 articles related to forensic identity testing. He currently serves on the editorial board of the following journals: Applied and Theoretical Electrophoresis, BioTechniques, International Journal of Legal Medicine, Crime Laboratory Digest, and Genetic Analysis: Biomolecular Engineering. In addition, he is the Chair of the Technical Working Group on DNA Analysis Methods (TWGDAM), the Chair of the DNA Commission of the International Society of Forensic Haemogenetics, and a member of the DNA Advisory Board. Peter De Forest John Jay College of Criminal Justice, The City University of New York, 445 West 59th Street, New York, NY 10019, USA Peter is Professor of Criminalistics at the John Jay College of Criminal Justice, where he has taught for 28 years. Prior to joining the faculty and helping to found the forensic science BSc, MSc and PhD programmes at John Jay and the City University of New York, he worked in several laboratories. He began his career in forensic science at the Ventura County Sheriff’s Crime Laboratory, Ventura, California in 1960. He earned a Bachelor of Science degree (1964) in Criminalistics and a Doctor of Criminology degree in Criminalistics (1969) from the University of California at Berkeley, under Dr Paul L. Kirk. In addition to his university teaching and research activities, he serves as a scientific consultant and expert witness for police departments, prosecutors’ officers, municipal law departments, public defender agencies and private attorneys in criminal and civil casework. He is the author or co-author of several book chapters, a textbook and numerous articles in scientific journals. In addition to membership in several scientific societies, he is a member of the editorial boards of the Journal of Forensic Sciences and the Crime Laboratory Digest. Since the inception of the American Board of Criminalistics (ABC), Peter has served as the chairman of its Examination Committee. He has presented lectures and workshops for several professional societies and in other universities and has served as Visiting Professor at the ix Notes on Contributors University of Strathclyde, Glasgow, Scotland. During the latter part of 1997 he served as Exchange Professor with the National Crime Faculty at the Police Staff College, Bramshill, England.
