In the last years in Hungary continual decrease of homicidal cases could be registered, however other forms of violence, severe injuries followed by the death of the victim are almost as high as formerly. Author in the last ten years performed autopsy of 14 such cases. On the base of them summarizes problems arising in connection with the medico-legal investigation of them. He concludes that among these problems-beside alcoholic intoxication-the most important is to reveal the natural disease-if any-of the victim. If there is a natural disease it may be accounted as a factor in the death. Then the crime can be evaluated as a praeterintentional one.
