This book is an introduction to the application of biology in legal investigations. Fully revised and updated throughout, the second edition of this highly successful textbook offers an accessible overview to the essentials of the subject providing a balanced coverage of the range of organisms used as evidence in forensic investigations; invertebrates, vertebrates, plants and microbes. The book provides an overview of the decay process and discusses the role of forensic indicators – human fluids and tissues, including blood cells, bloodstain pattern analysis, hair, teeth, bones, and wounds. It also examines the study of forensic biology in cases of suspicious death.

Includes a supplementary website (www.wileyeurope.com/college/gunn) covering additional material and self-test questions to reinforce student understanding. From the reviews of the first edition: "The author does an excellent job of demonstrating how biological science can, and does, contribute to legal investigations..." —THE QUARTERLY REVIEW OF BIOLOGY "...a super book ...not a book that will languish on library shelves. Buy it!" —JOURNAL OF BIOLOGICAL EDUCATION "...naturalists and biologists will find much of interest within these books...new light on the application of their own specialism..." —THE NATURALIST "Overall, I give it my highest recommendation. I was unable to find a single paragraph that was no fascinating, despite being sad or gruesome at times." —E-STREAMS
