New autopsy signs in violent death.

In forensic medicine subtle observation has often resulted in the detection of single findings which are of great significance regarding the mechanisms of development of the incidence or its vitality. Thus, empiricism is an accepted method to gain new insights. Nevertheless the value and the significance of empirically gained insights have to be proven either by retrospective or prospective analysis of important case series or by experiments. It is often a long and difficult way from observation to proof. But without a detailed and evidence-based scientific argumentation the level of empirical methods could not be exceeded.
