Digital traces are omnipresent in the present criminal investigations. These include messages, photos, videos found in our cell phones or computers. However, can we say that these traces completely replace fingerprints or DNA samples? Are they complementary and in this case, what is their added value? In reality, these traces provide a dispassionate view of the course of a crime, from its conception to its realization, exposing also possible complicities and attempts to conceal.
With examples of some real cases, David shows us the power of these traces in the characterization and resolution of a crime. The fascinating world of scientific investigations gives us a first-rate look at the impact digital traces are having on criminal prosecutions and trials.
