After the autopsy, Team Xu had a phone call with Brother Ming and said that as long as he agreed to bury Chen Xiaoyu, his grandfather Chen Shiyuan would be willing to tell the origin of the female body. However, in order to eliminate the impact of the open coffin on Feng Shui, Chen Shiyuan must personally bury him. My grandson found a new piece of Feng Shui land to move his grave. In line with the principle of handling special cases, the leaders of the municipal bureau agreed to his request. Brother Ming originally thought that after the autopsy, he would go directly to meet Chen Shiyuan for a while, but at this point, he could only wait patiently.
Back to the department, we cannot stop for a moment. The materials removed from the corpse must be classified and inspected as soon as possible.
After 6 hours of hard work, the case meeting scheduled for 1 a.m. was held on time.
Seeing that everyone was seated, Brother Ming said, "There are no new findings in the forensic autopsy. Ye Qian, please tell me about the investigation of the criminal police team."
Ye Qian replied "Okay" and then opened her notebook: "Chen Xiaoyu's grandfather Chen Shiyuan spat out. He spent 100,000 yuan to buy the female body from a man named He Gui. His true identity has been found out. . He Gui, male, was born on November 1, 1962. His external identity is "half-immortal". He makes a living by circling graves, looking after land, and helping people with their affairs. The fight between villagers and the police alarmed him, and he has now absconded. The operational technical detachment has figured out his escape direction and is pursuing it with all its strength. In addition, we have also sorted out the missing persons reports in the past three months one by one, but we have no clue at the moment. That¡¯s all the criminal police team has for the time being. "
Brother Ming stopped writing and looked at me: "Xiaolong, tell me."
"I collected the teeth, handprints and footprints of the deceased and searched through the system, but there was no corresponding record. Nothing else."
Brother Ming may have expected that I would come to this conclusion. He nodded gently, then turned his eyes to Lao Xian: "Guo Xian, what's the situation over there?"
Lao Xian scratched his nose and calmly extended a slap: "There are five points.
¡°First, the mourning clothes worn by the deceased are very new, made of acrylic fiber, rough in workmanship, and cheap. They can be purchased in any funeral shop. The distribution rate is very high and not targeted.
"Second, the residues in the nails of the deceased were found to contain limestone components. Limestone is mainly calcium carbonate deposited in lakes and seas. After losing water, it is compacted and cemented to form a rock. Its mineral components are mainly calcite, and Some impurities such as clay and silt sand. The formation of most limestone is related to biological processes. This kind of rock is very common in the mountains of our Yunxi City.
"Third, sodium cyanide was detected in the stomach contents of the deceased. Sodium cyanide is in the cubic crystal system, and its physical properties appear as white crystalline particles or powder, which is easy to deliquesce and has a faint smell of bitter almonds. It is highly toxic and can be exposed to skin wounds. It can cause poisoning and death if inhaled or swallowed in trace amounts. It is easily soluble in water and easily hydrolyzed to generate hydrogen cyanide. It is an important basic chemical raw material and is used in basic chemical synthesis, electroplating, metallurgy and organic synthesis medicine, pesticides and metal processing. .
"Fourth, the tea the deceased drank contained a large amount of tea residue. After analyzing the ingredients, it was found that the tea he drank was Lu'an Guapian, a specialty of our Baynan Province. Lu'an Guapian is the only tea without buds and stems. Made from a single leaf. Removing the buds not only maintains the single shape, but also has no grassy smell; the stems have been lignified during the production process, and after being removed, it can ensure that the tea is strong but not bitter, fragrant but not astringent. This kind of tea There were very few broken leaves, but the tea drunk by the deceased contained more broken leaves. It is speculated that its quality should be inferior tea.
"Fifth, the semen extracted from the vagina of the deceased was found to be male, and the genotype is xy. There is no relevant record in our system. Referring to the series of murders in the Baiyin area solved by the Ministry of Public Security some time ago, I specifically used the y genotype. A comparison was made.¡±
Lao Xian paused and continued: "We all know that when fertilized eggs are combined, the x genotype of the male fertilized egg comes from the mother, while the y genotype comes from the father. The mother has two x's, but the father has only one y. Therefore, the expression of Y gene is relatively stable. For example, the similarity of Y genotypes among men of the same clan can reach 99%, or even higher. So I used this as a breakthrough and directly searched for the suspect's Y gene in the DNA system. Type, and found these three people.¡±
Lao Xian said and handed three pieces of household registration information to Brother Ming: "The three of them are cousins ??and a tomb robbing gang. They were prosecuted three years ago on suspicion of stealing ancient tombs and illegally selling cultural relics. The boss, Wei Guangsheng, was sentenced to life imprisonment. The second oldest Wei Ming was sentenced to 13 years in prison, and the third oldest Wei Shudong was sentenced to 10 years in prison. The Y genotypes of the three of them are 99.9% similar to the suspect in this case. Therefore, I have reason to suspect that the suspect is related to these three Brothers should be related through ancestors. According to the Chinese habit of living with the same clan, maybe they live in the same village."
"Brother Xian, thiefAre the three of us locals from Yunxi City? "I asked.
"Yes, 3 people live in Wafang Village, Shouzhou County."
¡°I would like to add two points to Guoxian¡¯s conclusion.¡± Brother Ming put down the A4 paper in his hand and spoke:
¡°The deceased¡¯s fingernails contained a large amount of limestone, and he drank tea with the suspect before his death. Combining these two clues, the murder location should be a courtyard.¡±
"How do you tell it's a courtyard?" Ye Qian was always straightforward about questions she didn't understand. However, her question also happened to reveal our feelings.
Brother Ming patiently explained: ¡°In many places in our Yunxi City, there is a habit of going up the mountain and smashing rocks to pave the yard. This is one of them.
"Secondly, we know that the murderer dragged the body for a certain distance after committing the crime. And because the scratch marks on the back of the body were not obvious, it shows that the dragging time was not very long. From this, we can judge that although the murder occurred outdoors, This 'outdoor' area is not very large.
¡°Thirdly, there are bamboo mat indentations on the back of the body, which means that there must be a bed at the place where the crime occurred, so this place should be a residence.
"Finally, let's analyze the suspect's criminal psychology. He was alone with the deceased and dared to directly poison the drink. Therefore, strangers were not allowed to disturb the surrounding environment. In other words, the place where they were alone was a closed environment to the outside world. , then the first murder scene should be in a courtyard paved with rocks."
Brother Ming spoke in an understatement, but we were dumbfounded. He was able to peel off two seemingly unrelated clues and find a connection. We were really dissatisfied.
Brother Ming picked up the tea cup and moistened his throat, and then said: "The three tomb-robber brothers lived in Shouzhou County. In ancient times, Shouzhou County was a strategic point between the north and the south, and it was a place that military strategists repeatedly fought over. The Battle of Feishui in 383 AD was It happened there. Because of the special historical background, it was also the place where the royal nobles gathered most. The local residents have the habit of recognizing their ancestors and returning to their clan. We only need to find out which ancestor of the three of them continues the incense and check the genealogy. Maybe it¡¯s a shortcut.¡±
Fat Lei, who was afraid to breathe just now, listened to Brother Ming's words and sighed with his mouth shut: "Twelve hours ago, I was still in a state of anxiety, but now I can finally go out and have sex with peace of mind. ." Fat Lei's words instantly enlivened the atmosphere in the conference room.
"Don't worry about eating for now. There are three key tasks that need to be completed by the brothers of the Interpol Team."
"Director Leng, please tell me."
"First, He Gui must be captured as soon as possible and notify me if there is any news. Second, find out the suspect's genealogy and screen out all the information about qualified personnel. Third, go to the prison to interrogate the three Wei brothers and inquire from the side. Let¡¯s see if there are any relatives in his clan who are engaged in selling corpses.¡± (Remember the website address: www.hlnovel.com
