What Is the Course of the Ligature Mark on the Neck?

Hess was a frail 93 year old man with no strength left in his hands who could just barely drag himself from his cell into the garden. The argument is that his weak possibly arthritic hands shouldn't have been able to do this. Dr. Cameron concluded that Hess died of his fixia caused by compression of the neck due to suspension or hanging rather than being throttled or strangled with a cord. In forensic medicine, the course which the ligature mark takes on the neck is considered a classic indicator for differentiating between forms of hanging and throttling.
