Description

Most murderers use a weapon. One of the top-priority tasks for detectives is to find that weapon. It can lead to the killer but it can also reveal so much more. Using cutting-edge forensic techniques, the murder weapon can now give us an insight into the mind of the killer. This program examines the murder weapon that until 150 years ago left no trace, how 3D crime-scene modelling is revolutionising gun crime investigations, and why, until recently, much of what we knew about fire analysis and arson was wrong. A BBC Production.
