Chapter 15 I was really scared to death
8:14 pm.
Major Crime Unit Office.
Except for Shang Lu who was still in the dissection room, the others were either sitting or standing. Gu Nankai said, "A day has passed. Let's talk about the progress of our work."
His eyes looked at Cao Cang, who was originally sitting, and stood up when he saw his signal. Li Meng and Gao Yuan were originally standing, and when they saw Cao Cang stand up, they looked at each other. Gao Yuan shrugged nonchalantly, and the two sat down.
Cao Cang cleared his throat: "Let me tell you about my findings first."
Seeing that everyone's attention had been drawn, he turned on the electronic screen and said, "The murderer's scene was handled very cleanly. It is difficult for us to extract physical evidence about the murderer. This footprint should be left by the murderer accidentally getting blood on him when he killed and dismembered the body. We only extracted one. Let's take a look."
He walked closer to the screen and pointed at the picture on it to explain: "Through the gait characteristics of this footprint, we can infer that the murderer's gait after landing is a pressure mark. The so-called pressure mark is that when one leg is supported, the foot on the side that bears the weight produces biased pressure, leaving an impression of the upper shoe. This feature that can reflect the upper shoe impression is called a pressure mark, so I boldly speculate that the murderer was able to leave such an impression, and we have difficulty finding a second footprint. Is it because he has a disability in his legs?"
"We only found one shoe, and the shoe print was stained with blood. If he left wearing the shoes, he would definitely leave marks. So the murderer took enough time to change his shoes when he left." Gu Nankai stared at the shoe prints and said, Cao Cang nodded and continued, "We can vaguely see that the shoe prints have a block pattern. This pattern is too common. We can hardly find any clues from this point, but I found a strange phenomenon through the shoe prints."
"Oh? Tell me about it." Gu Nankai stood up from the back of the chair, propped one hand on the table, and bent his index finger slightly. Cao Cang continued: "From the shoe prints, we can know that the murderer's feet are as long as a middle-aged man, but when I calculated the murderer's weight from the traces of the shoe prints, I found that the murderer weighed only the weight of an adult girl."
"You mean, the owner of the footprints is a man with the feet of a middle-aged man but the weight of an adult girl?" Wu Qingluan took over, Cao Cang nodded, and he rarely showed humor, and added: "I'm talking about a slender adult girl, a girl."
"What do you think?" Seeing that Gu Nankai didn't speak, Wu Qingluan turned her eyes to him. Everyone looked at Gu Nankai and waited for him to speak. Gu Nankai stared at the screen, thinking about Cao Cang's words in his head. After a long time, he said: "Can you calculate his height?" He pointed to the screen: "According to this footprint."
Cao Cang nodded, but it seemed that he did not trust the result of the calculation: "His height is about 1.3 to 1.5 meters."
"But as far as we know, Sheng Yuandong is tall and big. How could such a person kill Sheng Yuandong?"
Gao Yuan curled his lips, leaned back and expressed his doubts.
"Now I believe that Sheng Yuandong was really scared to death." Gu Nankai exhaled heavily: "We will know when the report on Shang Lu's body comes out." He continued to look at Cao Cang: "The murderer didn't find the tools he used to dismember the body at the scene."
Cao Cang shook his head: "No, the scene was very clean. If the murderer was not extremely experienced, he must have had enough time to clean the scene. If so, the purpose of him leaving this footprint is worth pondering."
"Well, let's wait for Shang Lu's autopsy report to come out and see if there are any new details." Gu Nankai motioned Cao Cang to sit down. He looked at Gao Yuan and said, "How are you and Li Meng doing?"
Gao Yuan straightened himself. Although he usually looked lazy, he seemed to change when it was his turn to appear. He put on his thick glasses without lenses and began to report: "Everyone has received the information about Sheng Yuandong. Then Li Meng and I went to Kaisheng Group and learned that Zhao Kaichuan was on a business trip and would not be back until tomorrow, so we went to visit Lin Lin, Zheng Yi's wife."
"Ten years ago, Zheng Yi was only in his twenties. I didn't expect that he was already married." Wu Qingluan interjected. In her opinion, Zheng Yi had devoted his heart to starting a business at the time, and he was full of vigor and vitality. Starting a family did not seem to fit his personality.
Gao Yuan chuckled: "Not only is she married, she also has a child!"
Seeing the surprised expression on Wu Qingluan's face, Gao Yuan smiled and continued, "Zheng Yi's parents are typical rural people. They found a wife for Zheng Yi a long time ago. Zheng Yi was not interested in this and did not want to disappoint the old couple, so he got married. Not long after the marriage, his wife became pregnant. Zheng Yi also made some money, so he brought his parents to live with him."
He slowed down, picked up the cup in front of him and took a sip of water and continued, "Then everyone knows that the insurance salesman, hey, this old couple met, and after being talked around, the old couple took out their life savings and bought insurance for their son. Zheng Yi and Sheng Yuandong's cooperation was in trouble and they owed a large sum of money to others. He was responsible for it. It was a huge sum of money. At this time, the insurance his parents bought became Zheng Yi's last hope."
"The insurance company for Zheng Yi's car accident has also conducted an appraisal, otherwise they would not have been able to get the money." Li Meng had remained silent until he interrupted, which caused Gu Nankai to agree: "That's right, since the Zheng family was able to get the money, it means that Zheng Yi's death was an accident, not someone's plan."
" But according to our understanding, Zheng Yi had no idea that his parents bought insurance. If it was a coincidence, it's such a perfect coincidence." Gao Yuan pushed the frame of his glasses with his index finger and expressed his doubts.
"It's indeed a perfect coincidence." Gu Nankai nodded in agreement: "But there are a few questions. If we figure them out, we may be able to find the connection between Zheng Yi's death and Sheng Yuandong's death."
When Gu Nankai finished speaking, Shang Lu walked in with a report in his hand. He shouted to everyone, "Just as I expected, Sheng Yuandong was frightened to death."
The real cause of Sheng Yuandong's death was actually being frightened to death, which surprised everyone present. Shang Lu sat down on the chair, picked up the cup in front of her and drank it all. After she quenched her thirst and felt comfortable, she explained: "When a person is suddenly and unexpectedly frightened by the outside world, the brain will instruct adrenaline to secrete a large amount of catecholamines, which is a kind of neurotransmitter, including adrenaline and norepinephrine, which are mainly secreted by the adrenal glands. When a person is in an extremely frightened state, the adrenal glands will suddenly release a large amount of catecholamines, which will cause the heart rate to suddenly accelerate, blood pressure to rise, and the oxygen consumption of myocardial metabolism to increase sharply. The excessive blood circulation hits the heart like a flood, tearing the myocardial fibers and causing heart bleeding, leading to cardiac arrest and death. Through the autopsy of Sheng Yuandong's body, it was found that the myocardial cells of the deceased were damaged to varying degrees, and there were many red rose-colored blood spots in the myocardium, indicating that excessive bleeding damaged the heart function and death."
"Oh my god, there really are people who are scared to death." Li Meng was stunned and said excitedly.
While reading the autopsy report, Gu Nankai asked, "What about the tools? Can we find out what tools were used to cut off the victim's head and dig out his eyeballs?"
Shang Lu pursed his lips and nodded: "Judging from the fractured layers on the victim's head and neck, the murderer should have used something like a saw to cut off the victim's head, and his eyeballs were directly dug out by the murderer using something like a spoon."
