Question 7

A body is found suspended from a ceiling fan. The neck shows a transverse continuous mark below the thyroid cartilage, the face is deeply congested with conjunctival petechiae, and the hyoid greater cornu is fractured. What is the most likely sequence of events?

Accepted Answer

Every feature contradicts hanging. Hanging gives an oblique interrupted mark above the thyroid cartilage, and complete suspension typically produces a pale rather than congested face because arterial inflow is also stopped.

A transverse continuous low mark, intense congestion with petechiae and a fractured hyoid are the findings of ligature strangulation. The most likely sequence is homicidal strangulation followed by suspension of the body to simulate suicide. Confirmation would come from a layered bloodless-field neck dissection looking for vital reaction at the base of the mark.
