Fatal falls from a height: two case studies

Two case studies are presented involving fatal falls of adult females from a height. One involved a launch at low speed from a balcony, and one involved a launch at high speed from the top of a cliff. Crime scene evidence obtained on the balcony itself provided a strong indication of homicide, but subsequent investigation showed that the fall was accidental. No crime scene evidence was obtained for the cliff fall since the fall initially appeared to be just another suicide from a popular suicide spot. Subsequent investigations indicated homicide based on measurements of cliff height, horizontal distance to the impact, and available runup distance, plus measurements of possible run, jump, and throw speeds. It was found that a female weighing 61 kg (134 lb) can be thrown at speeds up to 4.85 m/s by a strong male, more than enough to account for the estimated launch speed (4.5 m/s). Given the available 4.0 m runup distance, it was found that women of better than average rather than elite athletic ability can dive at speeds of about 3.5 m/s or jump feet first at speeds of about 4.0 m/s, both being less than the estimated launch speed. The decedent had no athletic ability and landed head first after falling through a height of 29 m.

Different Mechanisms of Decapitation: Three Classic and One Unique Case History

Abstract: Three classic cases and one exceptional case are reported. The unique case of decapitation took place in a traffic accident, while the others were seen after homicide, vehicle‐assisted suicide, and after long‐jump hanging. Thorough scene examinations were performed, and photographs from the scene were available in all cases. Through the autopsy of each case, the mechanism for the decapitation in each case was revealed. The severance lines were through the neck and the cervical vertebral column, except for in the motor vehicle accident case, where the base of skull was fractured. This case was also unusual as the mechanism was blunt force. In the homicide case, the mechanism was the use of a knife combined with a saw, while in the two last cases, a ligature made the cut through the neck. The different mechanisms in these decapitations are suggested.     

论中国如何利用《联合国海洋法公约》有拘束力争端解决制度

有拘束力争端解决制度是《联合国海洋法公约》争端解决制度的第二步．穷尽第一步即争端方通过自身努力用和平方式解决争端，或依靠外力如斡旋、和解、仲裁等之后才能适用。谊制度适用于南海争端。中国应在南沙群岛划定领海基线，运用跳出机制，申请临时措施，要求船员或船只迅速释放。依靠“历史性权利”声索海域权利等方面更好地利用有拘束力争端解决制度。
