Case in brief
A 29-year-old man was found dead in a bathtub with 24 rubber bands tightly encircling his neck and two hemorrhagic forearm wounds. Autopsy and whole-body CT did not establish whether death resulted from bleeding or cervical compression. The authors used an experimental biomechanical analysis based on Hooke’s law and other physical principles. The bands’ cumulative tension corresponded to a mass-equivalent force of 35.11 kg, which literature indicated was sufficient to occlude major neck vessels and the trachea. The findings strongly supported asphyxia from cervical compression as the primary cause of death.
What made this case unusual
The fatal mechanism was uncertain despite autopsy and whole-body CT; biomechanical analysis of the rubber bands helped distinguish cervical-compression asphyxia from external bleeding.
Diagnostic / clinical pearl
When autopsy and imaging do not resolve the fatal mechanism in a ligature death, biomechanical assessment of the ligature’s tension may help evaluate whether cervical structures could have been compressed.
