While Lu Chuan was conducting the crime scene investigation and analysis, the forensic doctor was also performing an autopsy on the body.
The conclusion reached at the scene by Lu Chuan was not much different: the fatal injury was the mark on the neck; a rupture of the carotid artery led to massive blood loss, ultimately causing death by shock.
The carotid arteries are located on either side of the trachea and are the most easily perceptible arteries in the human body.
By placing a hand over either side of the throat, one can clearly feel the pulse of the carotid arteries.
The bleeding from an arterial injury is very different from a venous injury; when an artery is injured, the blood gushes rather than flows.
When the carotid artery is traumatized, the blood can spray up to three meters.
However, an injury to the carotid artery does not cause instant death; the bleeding process can last from 3 to 15 minutes.
