## Ligature Mark Pattern in Hanging **Key Point:** The ligature mark in hanging is characteristically **oblique**, running upward and backward toward the angle of the jaw and mastoid process, due to the direction of the suspension force. ### Mechanism of Mark Formation When a person is hanged: 1. The rope/ligature is typically placed around the neck with a knot positioned at the side or back 2. The body weight pulls downward and backward 3. This creates an **oblique angle** rather than a horizontal or circular mark 4. The mark ascends toward the point of suspension ### Distinguishing Features | Feature | Hanging | Strangulation | |---------|---------|---------------| | **Direction of mark** | Oblique, upward-backward | Horizontal, level | | **Mark pattern** | Single or incomplete | Usually complete circle | | **Position** | Often above larynx | Usually at/below larynx | | **Knot location** | Usually lateral or posterior | Variable | **High-Yield:** The oblique direction of the ligature mark in hanging is a **key forensic finding** that distinguishes it from strangulation, where the mark is typically horizontal due to manual pressure applied from the front. **Clinical Pearl:** The angle of the oblique mark can help determine the approximate height of the suspension point and the direction of the force applied.
