Serious Crime Unit 1

Chapter 723 Drowning (3)
"If the murderer is too strong, he tightly grasps Fang Deng's feet, because he is wearing thermal pants and jeans. Under the cushioning of soft thermal pants, it is not easy to leave scars. In addition, he was soaked in river water for more than 20 minutes. Even if there are shallow scratches, it is not easy for us to see. This is the strength of the murderer. You first dissect the bass and test the water in its belly to see what kind of water it is."

"Captain Jiang, after all these years of working as a forensic doctor, I have never dissected a body on a bass. I didn't expect to meet one today." Luo Jin said with a smile.

"There is a first time for everything, and the first person to teach at a university is definitely not a college student."

Luo Jin dissected the sea bass, and then took the water in its belly to the laboratory for testing. The results proved that the water had no salt and was fresh water. This means that the sea bass was raised in a farm and was definitely not a sea fish or river fish. This can be proven Fang taking the stage belongs to murder!

This created an inexplicable pressure on everyone. First, the Guanshan Road case had not yet been solved, and a new murder case had occurred. Second, the murder suspect was so clever that he made it look like he accidentally fell into the water and drowned.

Luo Jin and his assistant went on stage to conduct an autopsy.After they took off his clothes, they conducted a post-mortem examination.Fang Deng is 168 centimeters tall and weighs 50 kilograms. His skin is smooth, delicate and slightly dark, but after being soaked in blisters, his whole body was swollen a lot.

Luo Jin shone a bright light on the corpse and observed carefully. He found that the skin at the Sanyin junction of the corpse's two little feet was slightly scratched. If you don't observe carefully, it is difficult to see. This means that his feet were tightly bound by the murderer. Grabbing, he was struggling so hard that he got this tiny scrape.

After Luo Jin took pictures of the bruises, he checked the abdomen, chest, neck and chest, and then checked the head and hands. The result was that there were no scars at all.There are no fibers, skin tissue, or sediment in the gaps between nails.

They used scalpels to open the cranial cavity, chest cavity and abdominal cavity of the corpse and conduct dissections.The brain was intact, but there were a large number of alveoli in the lungs. There was drowning fluid in the alveoli, and "Tatia's spots" appeared on the surface. "Tardiao's spots" refer to those who died from mechanical asphyxia. Petechial bleeding is most common under the visceral layer of the lung pleura and pericardium. Congestive bleeding is also seen in other internal organs, including the thymus, thyroid, and small intestinal mucosa.Their shape, size, color, number, etc. are all similar to subconjunctival bleeding points.Therefore, the deceased undoubtedly drowned.

There was also 6000 ml of drowning fluid in Fang Dengtai's stomach, and there was also drowning fluid in his digestive tract. These are typical signs of drowning.Luo Jin was worried that Fang Deng would inhale anesthetics or poisons on stage and fall into the water and drown, so he did another poison and anesthetic test, and the results proved that there were no poisons or anesthetics.

Because there is visual evidence of orchestral music, the time of death is accurate to minutes. Therefore, there is no need to judge the time of death. No matter how Luo Jin uses scientific methods to judge the time of death, it is impossible to be accurate to minutes. Generally, it is judged within one hour. It's already great.

"After anatomy of the bass and testing of the water taken from the belly of the bass, it was proved that the water was fresh water, not river water. Judging from the scratches on the Sanyin junction of Fang Dengtai's calf, he must have been murdered. Everyone Think about it, are there any good clues?" Jiang Yiming and other team members sat in a small conference room for a case analysis meeting.

"If a suspect wants to commit murder, he must go to the wet market to buy seabass. There should be very few seabass weighing 15 pounds in the market, right? If you can find the source of the seabass, you can find out what the suspect looks like from the fish seller. Then based on the description of the fish seller, there should be clues. If we are lucky, we may also see the suspect in the surveillance video of the vegetable market. "

"There are at least thousands of large and small vegetable markets in the city. Finding a suspect among them is like looking for a needle in a haystack. It is faster to find the owner of the breeding farm."

"There are also more than 500 freshwater farms in the city, not including those from other provinces and cities. If the suspect buys seabass from other provinces and transports it to the scene to commit crimes, then all the efforts will be in vain."

"Yes, it is unreliable to find the source of sea bass. Nowadays, transportation is very convenient. There is a company in our city that flies seafood from Indonesia to the wet market for sale, and it is alive."

"The suspect must use diving equipment, otherwise it will be difficult to drown Fang Dengdai, who can swim, in the water. Therefore, diving equipment is a clue."

"The clue of diving equipment is also too broad, because not only are it sold in many stores and swimming clubs, but there are also many such online stores online, and they can even be purchased from abroad, so this is not a very good clue."

"Then we can only start the investigation from the perspective of who has the motive to kill." Jiang Yiming heard everyone discussing and felt that the clues about bass and diving equipment were not ideal. He always considered the fastest way to solve the case and tried to eliminate the need for a large number of interviews. clues.

"I think so too. I also have a bolder speculation: Is Fang Dengtai's death related to Guan Shanlu's death?" Xiao Ke looked at Jiang Yiming, then quickly looked away, glanced at everyone, and lowered his head.Seems very unsure. "Xiao Ke's speculation makes sense. To prove whether their deaths are related, check whether they have common friends, such as checking their call records and WeChat friends." Wu Jiang supported Xiao Ke.

"From the surface, the two deaths are not related, and the murder methods are different. Therefore, I think there is no necessary connection. However, to be cautious, everyone must check the stage during the visit. Does it intersect with Guanshan Road, even indirectly?" Jiang Yiming said.

"The murderer wants to go to the south bank of the Qianjiang River to murder Fang. He will definitely dive into the water not far from the scene. It is impossible to sneak into the waters from a very far away place to commit the crime. Therefore, we need to expand the scope of the search. It is best to do so in Within two square kilometers of the on-site water area.”

"What Zhou Ting said makes sense. I think it is more likely that the murderer dived into the water from the north bank of the Qianjiang River and then swam to the water area to commit the crime, because the north bank is a vast expanse of farmland with corn and sugar cane planted in the fields. The murderer should have hid in the water in advance. The observer was on stage fishing in the sugar cane forest, because the sugar cane forest can serve as a cover for the murderer and prevent him from being witnessed," Lu Yingying said.

"If Yingying's conjecture is true, then the murderer will definitely leave clear shoe prints in the sugar cane field, or may leave traces of oxygen bottles. Unfortunately, there is no surveillance camera there, so the murderer's appearance cannot be photographed."

"Yingying, why couldn't the murderer enter the water from the south bank or from the ship?" Xiao Ke felt that Lu Yingying's words were a bit arbitrary.

"The South Bank is entirely made of concrete river embankments. Next to the river embankment is the 5.2-kilometer-long Nan'an Road. There are many pedestrians on the road. The murderer would be worried about being witnessed by pedestrians and would also be worried about being filmed by the surveillance cameras on the road. Therefore, he should not Choosing to launch from the south bank, as for whether I will choose to launch from the ship, I dare not speculate."

"I support Yingying's point of view. The murderer needs time to observe whether Fang Chengtai went to the scene to fish and wear diving equipment. These equipment should have been brought to the north shore by the murderer in a big bag and then put on in the sugar cane forest. He went into the water, so he must stay out of sight. We are all going to the north bank to investigate now, and we will wait until the investigation is completed." Jiang Yiming asked everyone to break up the meeting and go to the north bank to search.

The north bank of Qianjiang is nearly 50 kilometers away from the city center. It was almost developed into a residential area by real estate developers. However, after the country issued a basic farmland protection policy, the district government ordered the development to be stopped and compensated the developer with bank loan interest and The upfront operating costs were reduced, so this piece of farmland worth thousands of dollars was not buried under reinforced concrete.

This piece of farmland covers more than 1000 acres, growing various vegetables and fruits. Some areas are covered by greenhouses. The transparent greenhouses shine in the sun. The government once issued a policy not to allow greenhouses to be built in vegetable fields.

First, greenhouses destroy agricultural production and occupy cultivated land and basic farmland; second, they infringe on the interests of farmers.After completion, such houses are rented and sold to urban residents, and they also come with greenhouses, causing farmers to lose their cultivated land and lose their long-term livelihood security. Third, they violate land management laws and regulations and endanger national food production security.But for unknown reasons, these greenhouses have never been demolished.

Most of the farmland near the river is planted with sugar cane. Some of the sugar cane has been harvested, but [-]% of it has not yet been harvested. Therefore, the murderer can use the sugar cane forest to hide.

Most of the trenches in sugarcane fields are wet. When people walk up them, they will leave obvious footprints. Because sugarcane likes moisture, sugarcane farmers will continuously pour water into the fields to make the sugarcane grow lushly until it is about to be harvested. Irrigation.

Lu Yingying and Luo Jin had a lot of work to do, so they did not come to search. Only Jiang Yiming, Wu Jiang, Xiao Ke and Zhou Ting came to the sugarcane forest. They were divided into two groups, starting from the middle of the sugarcane field closest to the river. The river flows into the sea from west to east. Wu Jiang and Xiao Ke went east to search; Jiang Yiming and Zhou Ting went west to search.

The sugar cane fields were trimmed into ridges, which are about 1.5 meters wide. Dense sugar cane is planted on the ridges. The ridges stretch along the direction of the river. Each ridge is determined by the length of the farmland, which is approximately 30 to 60 meters.So, they searched along the ditch.

Because the ditch was very narrow and could only accommodate a single person walking, Wu Jiang and Xiao Ke walked forward along the outermost ditch respectively.Wu Jiang is responsible for checking the outermost ditch, and Xiao Ke is responsible for the second ditch.As a result, before walking 30 meters, Wujiang made a discovery.
