Increasingly, forensic scientists use plant evidence to reconstruct crimes. The forensic aspects of this subject require an understanding of what is necessary for botanical evidence to be accepted in our judicial system. Bringing together the latest information into a single resource, Forensic Botany: Principles and Applications to Criminal Casework introduces the basic science underlying this emerging field of forensic botany. Contributors discuss the recognition of pertinent plant evidence at a crime scene, the appropriate collection and preservation of the material, and maintenance of a chain of custody. They also explain scientific testing methods, the validation of new forensic techniques, and admissibility criteria for court. An overview of plant biology and historical developments in forensic DNA analysis is also included, as well as case examples featuring the use of botanical evidence in a variety of criminal cases. In an effort to build the scientific foundation for this promising field, this book provides definitive coverage of forensic botany with detailed applications and case examples. It familiarizes forensic scientists with the role of botanical evidence in criminal investigations and its potential value in the pursuit of justice.

The association of a suspect with the victim or crime scene through DNA evidence is one of the most powerful statements of complicity in a crime imaginable. No category of evidence has ever had the complete capacity to convict or exonerate an accused so absolutely in the eyes of the public. With the discriminatory powers of DNA and the variety of DNA markers now in regular use, the one thing keeping a third of all cases unsolved is the lack of human DNA evidence. However, the identification of polymorphic genetic loci in cats, dogs, plants, insects, bacteria, and viruses can provide the critical link between suspect and scene in the absence of human DNA. Non-Human DNA Typing: Theory and Casework Applications provides an introduction to the basic science underlying the emerging field of non-human DNA typing. It examines the use of non-human DNA evidence not just in homicide cases, but also in drug trafficking, poaching of endangered species, livestock fraud, and missing persons, as well as the identification of primary and secondary crime scenes. The book demonstrates the recognition, collection, and preservation of biological evidence at a crime scene, techniques of DNA fingerprinting, and DNA profiling. Using a wide variety of examples, applications, and case studies, the author describes the STR analysis of canine and feline samples, insects, and fungi, and their role as evidence in forensic science. Chapters consider the development of testing methods for animal evidence, soil DNA typing, and the use of DNA typing in wildlife investigations. A useful appendix includes an overview of the history of forensic serology and DNA. Combining science, case examples, legal decisions, andreferences, Non-Human DNA Typing: Theory and Casework Applications presents the forensic and legal applications of non-human DNA evidence for scientists, law enforcement, and attorneys.
