| Abstract: | The intervertebral haemorrhages described by Simon in 1968 as a vital sign of hanging have been verified and endorsed by other authors. They occur in 40-50 % of hanging cases, most frequently in the lumbar spine, in younger age groups, and in cases of free suspension. The haemorrhages are not unique to hanging, but may occur in particular as a result of other traumatic elongation or overextension of the spinal column (e. g. in the course of traffic accidents). In cases of decomposition of the body, "false positive" findings are relatively common. As external findings scarcely provide any reliable vital signs of hanging, there is still a high demand for autopsies. In addition to Simon's bleedings, internal findings which are diagnostically conclusive also include microscopic examinations of the lungs and the neck musculature. More recent findings such as haemorrhages in the back and auxiliary respiratory muscles as well as the intestinal wall, if confirmed, could supplement Simon's bleedings. Frei's fibre sample and evidence of histamine in the ligature mark should not be neglected. Finally, it must be emphasized that the forensic assessment of hanging cases should always be based on a criminological and forensic evaluation of all the circumstances of the offence as well as on post-mortem findings. |
