Chapter 1204 Unknown Cause of Death (1)
1
Jiang Yiming convened a meeting to analyze the whereabouts of Du Qianqian, Feng Fangfang, and Huang Yasi. Everyone agreed that they should have been killed. The murderer was most likely Liu Dayu, but there was a lack of evidence.Everyone reached a consensus: the three of them may have been buried in Wild Boar Valley by Liu Dayu, because Liu Dayu was very familiar with the terrain there.According to the mentality of the murderer, most of them bury the deceased in a familiar place.

Jiang Yiming called Xiao Bing again and asked if his search dog could find human bones?Xiao Bing said with certainty: Let alone bones, just ask them to find the ashes, and they can find them.Jiang Yiming explained the situation to him, and he promised to take 5 search dogs to the Wild Boar Valley to search immediately, because the Wild Boar Valley has an area of ​​4 square kilometers and is relatively wide. The more search dogs, the faster the task can be completed.

Members of the No. 1 Major Crime Team cooperated with Xiao Bing. Xiao Bing brought 5 search dogs and 5 trainers and drove three vehicles to the Wild Boar Valley. After arriving at the Wild Boar Valley, they took the search dogs and searched separately. The dog soon found a female skeleton, then a second skeleton, and a third... After a day of searching, a total of 6 female skeletons were found, all buried 1 to 1.5 meters underground. Everyone was shocked!
After Wen Xiaorou saw it, she couldn't help but burst into tears. She hugged a pine tree tightly and couldn't stop crying... Lu Yingying took out a tissue to wipe her tears.

Luo Jin said: "To determine the time of death of the deceased, a more accurate judgment can be made based on the changes in bone color and bone quality and the use of physical and chemical detection methods. The bones in the soil are eroded by the surrounding environment, and the color of the bones will change with the burial. As time goes by, changes will continue to occur. At the same time, bones will also be eroded, and decalcification, weathering, cavitation, etc. will occur. The changes in bone color and bone quality have a relatively clear time range and can be compared one by one. "

He paused and continued: "Looking at the pubic symphysis and tooth wear of the skeletons, these skeletons are about 20 to 30 years old. They are all girls in their prime, and none of them have given birth to children. In the same kind of skeleton On the surface, men and women have different gender characteristics. The pelvis has the highest gender value, and the skull is second only to the pelvis. The trunk bones and limb bones are relatively less characteristic, and women’s limb bones are relatively slender. I am from The pelvis, skull, and limb bones indicate that they are all female.”

Jiang Yiming patted Luo Jin on the shoulder and comforted: "You have to work hard for a long time." Because extracting samples from the skeletons and doing DNA comparisons is a laborious and time-consuming task, and it also requires analysis to determine the time of death of the deceased. Not to mention there are so many skeletons?
"As long as I can find the parents of these girls and kill the murderers...I am willing even if I faint from exhaustion." Luo Jin's eyes were also full of tears.Although Luo Jin has seen thousands of corpses, this is the first time he has seen the skeletons of so many young women. Why did the murderer kill so many girls?Could the murderer be the same person?
Jiang Yiming told Xiao Bing and the others to call it a day and go home. They would conduct a careful investigation of the scene overnight. He believed that they would be able to find evidence to prove who killed these girls!Zhou Ting and Xiao Ke went to the police car and brought 7 small investigation lights. These lights have a battery life of up to 12 hours. They were divided into 3 groups, with two people in each group. Luo Jin treated them as public use.Responsible for collecting physical evidence such as insects and plant roots in the burial pit.

Others collected trace physical evidence.When a body is buried, the deceased is usually wearing clothes. Clothes of different materials remain in the soil for different times and in different states.Generally, woven fabrics can be retained for a shorter period of time, but it will take four to five years for significant morphological changes to occur. Leather and silk can be retained for 30 to [-] years.Sometimes, forensic scientists can also roughly estimate the time of burial based on the growth rings of plants attached to the deceased.

After 4 hours of investigation, the three groups completed the investigation. They found a total of 3 types of physical evidence in 6 different tombs, including tops, pants, shoes, socks, watches, bracelets, mobile phones, hair, and rubber bands. , wallets, rings... Among them, a string of agarwood bracelets is the most precious, and it is worn by men.

Good agarwood costs hundreds to thousands per gram.The price of agarwood bracelets ranges from [-] to several million.Natural agarwood is the oil secreted by fragrant trees after being damaged by lightning, typhoons, insects and ants. It is mixed with fungi and formed over hundreds of thousands of years. Although it is not wood in the true sense, it is also made from trees. Produced on the ground, it is also classified as wood.

Wen Xiaorou is an expert on bracelets. She took the bracelet and looked at it and said: "This bracelet is customized with special grade agarwood. There are only two in this city. Its price is at least 15 yuan. This should be the result of the murderer's carelessness." He fell into the pit where the body was buried. He might have been buried in the soil because he was nervous or couldn't find the bracelet. I have a friend who sells high-end bracelets in Teemall Mall."

"There shouldn't be many customized bracelets like this. Do you know what kind of customized bracelet it is?" Jiang Yiming asked.

Wen Xiaorou took out a magnifying glass, observed it carefully for a while and said: "Captain Jiang, look, there are micro carvings on this bead, and the English abbreviation of 'Liu Dayu' is engraved on it. The production date is August 2016, 8. You can be sure that the bracelet is It belongs to Liu Dayu."

Jiang Yiming took the bracelet and magnifying glass to check, and the result was just as Wen Xiaorou said, the bracelet was extracted from Tomb No. 3, which was enough to prove that Liu Dayu was the murderer.But why did he kill such a girl?

Jiang Yiming asked everyone to call it a day and go back to the team. It was already 10 o'clock in the evening. Everyone only had some biscuits and no lunch or dinner. Jiang Yiming invited everyone to go to his old Hunan restaurant for a late night snack.Regarding this outcome, everyone's hearts began to turn from sadness to joy. The only regret was that Liu Dayu, the devil, could not be brought to justice, but was killed by Ning Zhiwu.

The next day, Jiang Yiming asked Wen Xiaorou and Zhou Ting to take the agarwood bracelet and ask the two most high-end bracelet manufacturers in the city. After he saw the bracelets, he confirmed that they customized the bracelets for Liu Dayu. Liu Dayu customized the bracelets. The main reason is to ward off evil spirits and avoid ghosts.This is in line with Liu Dayu's psychology.Through the efforts of Luo Jin's team, they confirmed the identities of all the deceased, including Feng Fangfang, Du Qianqian and Huang Yasi.The other three girls were named Luo Lan, Liang Dang and Cheng Xiaofang. Except for Du Qianqian, they were all stage girls from other provinces. Luo Lan died in May 2015; Liang Dang died in November 5; and Cheng Xiaofang died. In June 2015.

The last deceased was Du Qianqian, who died in October 2018.Liu Dayu may have had a premonition that the police and Ning Zhiwu would find evidence sooner or later to bring him to justice, so he stopped.Ning Zhiwu and Huo Song persevered in tracking Liu Dayu, indirectly saving the lives of many girls. Otherwise, Liu Dayu would not have stopped. These girls were all from other provinces and had no intersection or hatred with Liu Dayu.Liu Dayu's only motive is to get pleasure from killing people.

All the six victims died of hyoid bone fractures, that is, they were strangled to death. With Liu Dayu's tall and strong figure, there was absolutely no possibility for the girls to escape when he attacked these delicate girls. Only people like Zeng Xiaoyi who had suffered Girls with escape training can survive in desperate situations.

After most people are choked by someone, their first reaction is to stretch out their hands to pull the murderer's hand away, instead of attacking the most vulnerable part of the man - the testicles.Zeng Xiaoyi was so lucky to escape from Liu Dayu's clutches.

Baiyun Park is located in the southwest of the city, nearly 8 kilometers away from the city center. It is the largest park in the city and the most visited park.There is a hill in the park called Shenxian Mountain.China Hotel is a five-star hotel, next to Baiyun Park, in the bustling area of ​​the city.

Many citizens go for morning jogs in Baiyun Park. Because there are many residential areas nearby and the population is very dense, Baiyun Park is the best place for them to run in the morning. The main reason is that the forest coverage rate is as high as 70%, and the lake water It covers an area of ​​25%, with beautiful mountains and clear waters and pleasant scenery.

At about 2022 o'clock in the morning on April 4, 15, Anli, who lives in Yuanjing Community, jogged along Lakeside Road. He has been jogging here for many years. His blood sugar was high. The doctor told him to exercise hard and adjust. Diet to lower blood sugar. Because he is only 6 years old, he does not need to take medicine. If exercise does not lower blood sugar, consider taking medicine.

As he ran, he suddenly felt heartache, his eyes darkened, and he lost his balance. He plunged into the Crescent Lake, lost consciousness, and continued to sink deeper into the lake without making any struggle.

Many spectators nearby screamed and ran up to take a look. A young man named Xiang Shang ran from a few dozen meters away. He quickly took off his coat, pants, and shoes, and plunged into the water with both hands. He cut the water with force and swam towards the place where Anli sank.

In less than a minute, he saw Anli. He stretched out his right hand and grabbed Anli's left arm tightly, dragging him to the surface of the water. Fortunately, Anli did not struggle, otherwise, it would be very dangerous to save people.Because a person who falls into the water will treat the rescuer as a life-saving straw and hug the rescuer tightly, making it impossible for the rescuer to carry out rescue operations, which may even lead to two people drowning at the same time.

Xiang Shang's water ability is very good. He was once a swimming champion in the Jiangnan District Medical System. The entire rescue process only took 3 minutes.He is a doctor at Jiangnan District Traditional Chinese Medicine Hospital and knows how to treat drowning victims.He placed An Liping on the cement road and performed CPR on him.Xiang Shang thought Anli would most likely wake up, but he didn't expect that Anli showed no reaction when he performed cardiopulmonary resuscitation for 5 minutes.
