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.
