14. The autopsy • Autopsy was done on the dead body of the thirty years old lady, who was noticed hanging from the bough of a “keekar” tree in a forest. The deceased was a divorced lady. • A shawl was tied around her neck, which belonged to the deceased. • As a slip-noose was used, ligature was in contact with the skin throughout the full circumference of the neck.

15. The cause of Death • There was mark of saliva dribbling from the left angle of her mouth. Except over the uppermost part of the right side of the neck ligature mark was faint and deficient on the back and sides. It was believed to correspond to the ligature material as soft as shawl. There was evidence of bruising on and around carotid vessels on the right side. • She had abrasions on the upper front of her both legs and also over right side lower outer front of the abdomen. There was no bony injury in the air passages like the fracture or dislocation of the hyoid or thyroid indicative of manual strangulation. • Cause of death by all standards was hanging.

16. The missing earrings • Doubt of homicide gained footings because father of the deceased held that earrings, that the deceased was always wearing, were missing from her ears. So much so the rumor of missing earring had converted in to news of recovery and seemed to have reached police ears while autopsy was going on. • Police expected autopsy doctors to provide some vital clues regarding the nature of hanging. Dismissing earrings based homicide theory autopsy team apprised police, true her ears were without any earring but there was no fresh or recent injury in her ears. • Ligature mark was believed to be the result of hanging, from a low point, for little period and in such a position that her legs were touching the ground. How could the body examination exclude that she could not and did not hang herself still appeared mysterious to the autopsy team

18. The confession • They confessed that one of them raped her. They then rendered her unconscious during throttling. • They also confessed of having created a scene of hanging. According to them in her efforts to escape she even fell and sustained some injuries on the front of her legs. Just because she removed her earrings herself to offer them for letting her go there was no injury on her ears. • They suspended her for two reasons. First they had doubt that she had not died and was still alive. They were so skeptical about her death that even after hanging her, one of them came back to the scene after sometime to make sure that she was really dead. • Another reason for hanging her, they told, was that they knew by creating a scene of hanging, even if she was noticed no one would suspect them. • A divorced young lady in the village would have several reasons to commit suicide.
