What Causes Rigor Mortis?
The Scene of the Crime:
“What was the time of death detective?”
“When we arrived, rigor had begun to set in. I place time of death at 4 hours ago.”
This scene is typical of a CSI murder drama. The Medical Examiner steps on the scene and examines the body for signs of rigor mortis.
