章 680: Chapter 648: Someone with the Surname An_1

Hearing the sound, several people ran over, Mr. Zhao went to take photos and collect samples, and Mr. Yang's face was full of guilt.

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

"I saw that you conducted a thorough examination inside and out. It's indeed easy to overlook such a small bloodstain, don't blame yourself."

Zhou Ning stood up and glanced at Mr. Yang.

"You didn't participate in the autopsy, so you don't know the condition of the deceased. 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.
