[A new sign for the establishment of gunshot in suicide?]
Abstract:
Two cases involving deadly bullet shots to the head are reported (entry wounds at the right temple, shots fired at absolutely close range, 7.65 or 9 mm caliber). In both cases bleeding was determined in the fissure of the right shoulder joint. This bleeding can be explained by hyperextension and extreme position of the joint at the time of the gun firing. Should further cases of bleeding be confirmed during additional autopsies, then this bleeding could be an indication of death "by one's own hand."
