    By the time the investigation was over, the sun had already set low, and Director Feng arranged for the police from the police station to take turns on duty to protect the scene.  In order to find out the source of the corpse, Ming Ge asked the criminal police team to investigate the missing persons in the province one by one in recent years.  After the arrangements were made, we all returned to the department to complete a procedure that had not been done in previous cases - salt analysis.

    As we all know, salt is often used to marinate meat.  The purpose of marinating is to preserve the meat and add flavor.  Its principle is that the osmotic pressure generated by table salt causes the salt to enter the tissue of the meat, and the water in the meat penetrates outward, partially dehydrating the tissue and inhibiting the growth and reproduction of harmful microorganisms, thereby achieving the purpose of preservation.

    The main factor that determines osmotic pressure is salt concentration.  The protein molecular weight of lean meat cells is large, and the molar concentration of the protein solution is small, allowing salt molecules to enter tissue cells smoothly and allowing water molecules to leak out of the cells.  The higher the salt content, the greater the osmotic pressure generated and the faster water can seep out.

    Salt precipitation is actually soaking in water to replenish the water lost in the cells.  The brine precipitated in the experiment must be boiled over high fire to produce salt, so that the ingredients and the amount of salt can be analyzed.

    The work of salt precipitation is divided into three major parts.

    I am responsible for changing the water regularly, Pang Lei boils the salt, and Brother Ming and Lao Xian have to observe the changes in the corpses at all times.  The first two are just physical work, and the last one is technical work.  For example, when dissecting a corpse, we will analyze the stomach contents of the deceased. Once the viscera is soaked in water for too long, the chyme in the stomach, esophagus, and large and small intestines will be mixed together, which will make the examination and analysis very difficult, so this  This work must be done accurately.

    Three days later, the salt precipitation came to an end. During this period, we also discovered an important clue: after being soaked in alcohol, the teeth of the deceased developed "rose teeth" characteristics.

    ¡°Rose teeth¡±, as the name suggests, means that the teeth are rose-colored.  It is characterized by rupture of capillaries in the dental pulp chamber.  In forensic medicine, "rose teeth" are an important feature in determining whether death was caused by mechanical asphyxiation.  It can be concluded from this that the victim was strangled and then quartered.

    As soon as the investigation by the Criminal Police Team was completed, Brother Ming organized the first special project meeting on this case.

    Brother Ming: "Ye Qian, tell me about your investigation."

    Ye Qian: "Our criminal police team is divided into two investigation teams. One team is sorting out the missing persons in the province within three years, and no missing persons who meet the requirements were found.

    "The other group is conducting an investigation around the 'Lejia Supermarket'. There is only this large supermarket in Heihu Town. Due to small profits but quick turnover, the supermarket has a large number of customers every day. The coarse salt used by nearby villagers to marinate meat is basically  from this supermarket.

    ¡°In addition, making bacon requires cutters, drilling knives, and leather and hemp ropes. I bought a set of these tools and gave them to Xiaolong and Teacher Guoxian in advance.

    "Later, Xiaolong proposed to help investigate the sales channels of the 'Manure Scoop'. According to the results of our visit, the 'Manure Scoop' disappeared as early as five or six years ago and is not available on the market. This is the general situation here.  many."

    Brother Ming: "Okay. Then let me introduce the forensic examination: the deceased was a female, about 25 years old, 1.75 meters tall, tall, had breast augmentation and bone reduction plastic surgery, had a history of childbirth, and had rose teeth.  'Characteristics, died of mechanical asphyxia. After the salt precipitation, the perineum of the deceased was observed, and no traces of lateral incision were found. There were minimally invasive incisions on the abdomen and uterus. Therefore, it can be determined that the delivery method of the deceased was cesarean section. I consulted  According to the relevant personnel of the National Health and Family Planning Commission, in our Yunxi City, there is only one private hospital called "Jiahehe" that can perform minimally invasive cesarean section. This hospital charges expensive fees, which is a problem that can be solved for a few thousand dollars in ordinary hospitals.  , it costs at least tens of thousands to go there. Although it is expensive, the conditions there are much better than those in public hospitals. In order to reduce the pain of childbirth, many pregnant women are willing to spend more and suffer less. Now that the two-child policy is open, ordinary maternal and child health hospitals deliver babies  The pressure is huge, which has caused a sharp increase in the number of consultations in private hospitals. According to the data sent to me by the National Health and Family Planning Commission, last year alone, more than 4,000 women underwent minimally invasive caesarean sections at Family Harmony. Forensic medicine is temporarily  There has been no substantial progress yet, Xiaolong, please tell me about the trace inspection."

    I organized my thoughts and said, "The knife used by the suspect to dismember the body was the cutting knife that Ye Qian bought in the supermarket in town. During the drying process, the cured meat needs to be perforated and hung with a rope. These characteristics are reflected in the body parts.  All of the above are reflected, indicating that the suspect knows the process of making cured meat.

    "I found a lot of traces of piled soil on the floor of the stone house. These were the traces formed after women's high heels hit the ground. Then Brother Xian found square metal pieces in the burning residue. These metal pieces are mostly used in shoes.  and the bottom to reduce wear. Judging from the size of the metal piece, the deceased wore it when going up the mountain.??A pair of "hate the sky high".  Wearing such high heels to go up a mountain is unreasonable, so I suspect that the deceased did not know that he would be taken up the mountain before he was killed.  The suspect temporarily proposed to go to such a remote mountain, and the deceased was able to agree to the other party's request even though he was not suitable for climbing, which shows that the deceased had considerable trust in the suspect.  Just think about it, what kind of relationship would lead a man and a woman to go deep into the mountains and forests?  "

    Ye Qian: "Falling in love?"

    "Congratulations, you will all be able to answer!" (Remember this website address: www.hlnovel.com
