    The meeting has progressed to this point, and we finally have a starting point. Immediately afterwards, Lao Xian pulled out another report.

    ¡°Brother Xian, what is this?¡± I asked.

    Lao Xian smacked his lips and showed an unfathomable expression: "This is a muscle tissue sample I extracted from the right calf of the deceased. The appearance of the tissue is purple-red, but no signs of infection or poisoning were found. This  Makes me confused.

    ¡°So I sliced ??the muscle sample and found that the protein in the muscle was completely denatured. The reason why it turned purple was because the blood deposited in the blood vessels produced a coagulation reaction when exposed to high temperatures.

    "I did an experiment. If the temperature suddenly increases, the skin tissue will be burned, causing obvious burns. But the dermal tissue of the corpse is tightly adhered to the muscle layer. In this case, I have been involved in carbon monoxide poisoning.  Encountered at the scene. The case occurred in winter. The deceased used a briquette stove for heating at home. During the heating process, he accidentally died due to inhaling a large amount of carbon monoxide. During the incident, the deceased fell from the bed, and his face happened to be on the  The furnace wall slowly heated up due to the heat, and finally left burn scars on the deceased's face. The tissue sections of the deceased's face were very similar to those in this case."

    Ye Qian: "Teacher Guoxian, are you saying that the inside of the deceased's calf was in contact with something that could slowly heat up?"

    Lao Xian: "Yes, and this object needs to be heated to above 100 degrees Celsius."

    Brother Ming: "Guoxian, how long does it take to form a mark on a corpse?"

    Lao Xian: "The heating process should not be too fast or too slow. I personally estimate that it will take about 30 minutes."

    "It takes so long?" Brother Ming frowned, "Now we can confirm that the person was killed during the heating process of the contact object. Otherwise, a living person would not have any stress reaction until the meat is cooked.  .¡±

    "After the murder, the suspect only put a pair of underwear on the deceased and hurriedly dumped the body, indicating that the time left for her was very tight, and she would not spend another 30 minutes alone leaving this mark on the body. Therefore, the mark is likely to be  left without the suspect's knowledge.

    "Just imagine, what do suspects usually do after completing a crime? It's nothing more than two things, dealing with the scene and disposing of the body. I was just thinking, would there be a briquette stove where the suspect lives? What if the suspect is there?  When cleaning the scene, the deceased's right calf just touched the surface of the stove to form a mark, which seems reasonable. But it is not winter now, the outdoor temperature is more than 30 degrees Celsius, and the briquette stove cannot be placed indoors. Since the mark was not left when the scene was being processed  Yes, it could only have been left behind when disposing of the body.

    ¡°There are two steps to disposing of a corpse: transporting the corpse and dumping the corpse.

    "We infer that the place where the corpse was dumped was a stone bridge without guardrails. The method was to drop heavy objects on the corpse. It is impossible to cause burns during this process. As a result, marks can only be formed during the process of transporting the corpse.

    "Transportation is required to transport the body from the place of killing to the place where the body was dumped. So I suspect that the burns were caused by the long-term contact between the body and the vehicle."

    ??Pang Lei said to himself: "What kind of transportation has an automatic heating function?"

    At this moment, Ye Qian and I looked at each other and shouted three words in unison: "Motorcycle!"

    In corpse dumping cases, the most common means of transportation are cars, motorcycles, electric vehicles, and rickshaws.  Cars and electric vehicles have no heating equipment at all.  Only motorcycle exhaust pipes have this function.

    Ye Qian is a professional racing driver. I have ridden in her road racing car more than once. Of course, I have also been burned by the exhaust pipe more than once.  The exhaust pipe of a motorcycle is made of metal, and all driving power comes from gasoline combustion. The longer the motorcycle is driven, the longer the high-temperature exhaust gas continues to heat the exhaust pipe, which will cause the temperature of the exhaust pipe to rise.  Come higher and higher.  We assume that the suspect placed the body on the back seat of the motorcycle, and the place where the inside of his right calf came into contact happened to be the exhaust pipe.

    "I agree with Xiaolong and Ye Qian's inference." Brother Ming changed the topic, "There are three tasks that need to be completed next; first, we must immediately screen the qualified Shiqiao upstream. Ye Qian, leave this to your criminal police team to complete.  ; Second, use the fingerprints and DNA information of the deceased to verify the source of the body. Leave this to Xiaolong and Guoxian; Third, after Xiaolong and Guoxian are finished, all of us in the department will participate in an investigation experiment, and I will control the content and process of the experiment.  ."
