Forensic Science: The Basics

Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law. Forensic science can help investigators understand how blood spatter patterns occur (physics), learn the composition and source of evidence such as drugs and trace materials (chemistry) or determine the identity of an unknown suspect (biology). Forensic science plays a vital role in the criminal justice system by providing scientifically based information through the analysis of physical evidence. During an investigation, evidence is collected at a crime scene or from a person, analysed in a crime laboratory and then the results presented in court. Each crime scene is unique, and each case presents its own challenges. This book explains every aspects of crime scene investigation, moving from basic areas of criminalistics and beyond to pathology, anthropology, and engineering. It also explores new and emerging areas such as forensic entomology as well as court testimony.
