Human Scent Evidence [EPUB ebook] 

During the last decade, scientific studies have supported using human scent as a biometric tool and indicator of the presence or absence of an individual at a crime scene. This book focuses on some of these recent advances in the use of human scent as forensic evidence. It examines theories of human odor production, the legal significance of results, and canine scent work from multiple search categories as described in the Scientific Working Group on Dog and Orthogonal detector Guidelines (SWGDOG). It also explores current trends in scent collection techniques, including devices, materials, and storage protocols.
