An unusual case of suicide by stabbing with a falling weighted dagger.
An unusual suicide by self-stabbing is presented. A 42-year-old man committed suicide with a dagger weighted with 2.72 kg in total and allowed to fall freely. The blade of the dagger fell from a height of 10 cm above the chest, penetrated the second left intercostal skin and pierced the upper lobe of the left lung. However, the weapon did not penetrate the chest skin from a stationary position in our trial at the autopsy. This finding confirms the results of experiments with stab wound dynamics which demonstrated that the impact velocity of the weapon as well as the sharpness of the tip is important for skin penetration.
