The body of a 26-year-old woman was found in a deserted building and brought in for postmortem by the police. On examination, the forensic surgeon notes peculiar findings on the body. The body is fully clothed with post-mortem staining on the back. Examination of the mouth and conjunctiva reveal petechial hemorrhages.

Three crescent shaped wounds are present on the left side of the neck. Another fainter abrasion is seen on the middle of the neck. What is the significance of these findings? Source: Koronfel’s Forensic Medicine
