A 40-year-old man is found dead with a ligature mark on the neck. The mark is pale, parchmentised, oblique, ascending towards a suspension point behind the left ear, with a gap at the apex (knot position). The finding at autopsy of fracture of the hyoid bone and thyroid cartilage would indicate:
- A Homicidal strangulation concealed as hanging
- B Suicidal hanging — these fractures occur in complete hanging due to neck weight
- C Judicial hanging — typical in judicial execution due to long drop ✓
- D Autoerotic asphyxia — fractures are characteristic
Explanation
In judicial (long-drop) hanging, the distance fallen (equal to the prisoner's height) generates enough force to produce atlanto-axial or hangman's fracture (C2 fracture) as well as fracture of the hyoid and thyroid cartilage. In suicidal hanging (incomplete/partial), the body weight alone usually does not generate sufficient force to fracture the hyoid; such fractures are more characteristic of judicial hanging or strangulation. Hyoid fracture in an apparent hanging case must raise suspicion of homicidal strangulation, but in judicial execution it is expected.
