Overview

Does the gunshot residue reveal how far from the target a weapon was fired? Is there any trace evidence to prove the accused handled a specific firearm? What is the likely behaviour of a ricocheting bullet? Do the marks on a bullet prove categorically that it was fired from a particular weapon? These are all issues (amongst others) that the fully revised and updated Second Edition of Handbook of Firearms and Ballistics: Examining and Interpreting Forensic Evidence covers in a clear and accessible manner. The book will be essential reading for all forensic scientists specializing in this subject, firearms examiners, defence and prosecution practitioners, the judiciary, police forces and all those involved in this field.

The Second Edition takes into account the most important new analytical techniques and methodologies that have now been implemented in the field. Fully revised and updated throughout, the book now includes a more comprehensive glossary, new case study material –including the Jill Dando murder enquiry – and a new chapter on the determination of bullet calibre via X-ray photography

• Completely revised and updated Second Edition of this successful book.

• Updated material on proof marks, muzzle attachments, non toxic bullets, GSR particles and SEM sampling.

• New case study material including the Jill Dando murder enquiry as a key example for reporting on GSR cases.

• New chapter on the determination of bullet calibre via X-ray photography.

• Now includes an updated and more comprehensive glossary to enhance understanding of the subject.
