Tao Zhenshan patted Mr. Yang on the shoulder and comforted him:

The victim was sitting in the car when the killer stabbed him in the heart, pushed the blade sideways, cutting through both lungs as well as the esophagus and trachea, causing the victim to instantly lose the ability to move. Then, the killer partially pulled out the blade and thrust it upward at an angle, severing the aorta.
