[Dynamics of decapitation after falling in a self-tightening rope noose].

In decapitation by dropping into a slip noose, it is in principle justified to doubt that suicide is involved. It must hence always be checked whether the dynamics to be inferred from the concrete facts can result in decapitation. Essential characteristics of the dynamics are the deceleration forces (tractional force of the rope) that are determined by the height of the drop, the directional force of the rope and the body mass of the victim as well as the density of the lines of centripetal force acting on the neck. However, the appropriateness of the dynamics must at all events be corroborated by compatible autopsy and scientific criminological findings with regard to the characteristic wound morphology, the intravital signs, the trace analysis and the topography of the fiber ablation traces on the rope that are due to the effect of heat.
