Incomplete Hanging
Definition
Hanging in which part of the body (feet, knees, buttocks) remains in contact with a surface. Biomechanically equivalent to complete hanging because the partial weight still exceeds the threshold for carotid and venous occlusion.
- Contact point
- Feet, knees, or buttocks touching floor or ground
- Force threshold
- Roughly 2 kg of traction occludes the jugular veins
- Frequency
- More common than complete suspension in hanging deaths
- Key finding
- Ligature furrow still oblique, not horizontal
Common questions
Does partial body support rule out hanging as the cause of death?+
No. Because carotid and jugular occlusion needs only a few kilograms of traction, even a body kneeling, sitting, or partly resting on the floor can still develop enough tension in the ligature to cause fatal vascular occlusion, so partial contact is not evidence against hanging.
How does incomplete hanging differ from a staged or assisted death?+
It does not differ mechanically. Investigators separate the two by scene reconstruction and injury pattern, checking for drag marks, defensive injuries, or a ligature mark inconsistent with self-suspension rather than by the degree of body support, which alone proves nothing.
