Forensic Science: A Very Short Introduction, 2nd Edition

Summary

Forensic science is a subject of wide fascination. What happens at a crime scene? How does DNA profiling work? How can it help solve crimes that happened twenty years ago? In forensic science, a criminal case can often hinge on a piece of evidence such as a hair, a blood trace, half a footprint, or a tire mark. Complex scientific findings must be considered carefully and dispassionately, and communicated with clarity, simplicity, and precision.

In this Very Short Introduction, Jim Fraser introduces the concept of forensic science and explains how it is used in the investigation of crime. He begins at the crime scene itself, explaining the principles and processes of crime scene management, and drawing on his own personal experience of high profile cases. Fraser explores how forensic scientists work; from the reconstruction of events to laboratory examinations. He considers the techniques they use, such as fingerprinting, and goes on to highlight the immense impact DNA profiling has had. Providing examples from forensic science cases in the UK, US, and other countries, he considers the techniques and challenges faced around the world. This new edition has been fully updated to take into account developments in areas such as DNA analysis and drug analysis, and the growing field of digital forensics.
