Forensic Medicine · Asphyxial Deaths (Mechanical Asphyxia, Drowning, Smothering)

At autopsy of a suspected hanging victim, the ligature mark on the neck is found to be oblique, non-continuous (with a gap at the apex), and situated above the thyroid cartilage. These findings are most consistent with:

  • A Typical suicidal hanging
  • B Homicidal ligature strangulation
  • C Manual strangulation (throttling)
  • D Homicidal hanging disguised as suicide
Correct answer: A. Typical suicidal hanging

Explanation

In typical hanging (point of suspension directly above), the ligature mark is oblique, rises toward the point of suspension, and shows a gap (discontinuity) at the apex/knot site. Its location above the thyroid cartilage is characteristic of hanging. In ligature strangulation, the mark is horizontal, encircles the neck completely without a gap, and is usually at or below the thyroid cartilage level. Manual strangulation leaves fingernail abrasions and bruises rather than a defined ligature groove.
