D F T F Chapter 190: Provocation.

“What is this sentence?” Li Hui asked in confusion.

Han Bin took out a pen and a notebook and wrote two words on them.

"Mosquito punishment."

The Chinese characters were wide and deep. Although there are only two words, everyone present vaguely understood the meaning.

"Brother Bin, you mean killing people with mosquitoes?" Zhao Ming guessed.

"It's true." Han Bin nodded and explained: "It is said that the mosquito punishment was created by Duke Huan of Qi to punish corrupt officials."

"Mosquitoes can also kill people?" Sun Xiao Ping couldn't believe it. He not only killed 80 this summer, but he also killed 100.

"Mosquitoes are small, so even though they can suck blood, they won't kill a person through ischemia," Tian Li said.

"When a mosquito bites a person, the first step is to inject a chemical substance into the human body. Its composition is very complex, mainly various proteins. Its main function is to prevent the body's blood from clotting, and it acts as a local anesthetic. This chemical will cause people to have a stress reaction, and the popular saying called it an allergy," Han Bin paused and said professionally: "When a person is bitten by a large number of mosquitoes, the cause of death is actually due to allergy. From a medical point of view, the cause of death is disseminated thrombosis within the capillaries, and the principle corresponds to death by anaphylactic shock.

Han Bin's knowledge was deep, and everyone was already a little surprised, and no one objected to the question.

"Since you can strip a person naked and tie them to a tree, there is an easier way to kill that person, why do you need so much effort?" Li Hui asked.

"This kind of punishment seems mild, killing people invisibly, but the ancients did not understand death by anaphylactic shock, thinking the prisoner was killed by the blood of mosquitoes. Many corrupt officials preferred going to jail or being beheaded rather than being slowly tortured. The significance of shock and deterrence is greater,” Han Bin explained.

Zheng Kaixuan had also heard of the mosquito punishment, but he didn't know the details very well. He hadn't thought of it for the first time. Now that he heard Han Bin's analysis, he nodded with satisfaction. It can also save a lot of hearts.

"Brother Bin, you are really good enough to understand everything," Sun Xiao Peng showed a touch of admiration.

Han Bin glanced at Li Hui and Zhao Ming and said with a smile, "Watch two fewer movies and read two more professional books, you understand everything."

Li Hui's constipated face reappeared.

Zhao Ming took it seriously: "Brother Bin is right, I will definitely study hard in the future and improve myself every day."

Zheng Kaixuan turned his head and looked at the clock on the wall: "Don't be poor, go to the scene."

......

When Han Bin and the other police arrived at Qingdao University, a cordon was set up around the pond, and many young people were already surrounding the scene, all students returning to school one after another.

"I haven't been to school for a long time, and I really miss it," Li Hui said emotionally.

"When you were in school, didn't you shout every day that it was boring to go to school and that you wanted to do an internship to become a policeman?" laughed Han Bin.

"I was young at that time, and I didn't know it was good to go to school," Li Hui showed a hint of reminiscence.

"Don't sigh, when you reach my age, old and young, you will miss the present day." Zheng Kaixuan snorted and led the people onto the stage.

"Captain Zheng, are you here?" Zhao Ying greeted him.

"How is the situation?"

"Wei Zimo, Du Qi, and the others take notes from the informant, and the technical team investigates the scene, and medical examiner Wu Xia does the autopsy." Zhao Ying has briefly introduced.

Zheng Kaixuan glanced at his watch and said with some annoyance: "It's been a long time since the incident happened, and the informant is yet unfinished describing what happened."

“The two informants were both students from Qingdao University, and they said they were dating in the woods at the time. Suddenly they saw the corpse, they were very scared and emotionally unstable, we comforted them for a while," Zhao Ying said helplessly.

"Brother Hui, you said the school is so big, why are they going out into the woods?" Zhao Ming winked.

“Ask Han Bin, this kid was doing a lot of that stuff back then.” Li Hui pursed his lips.

Han Bin didn't bother caring about it, and it was red fruit jealousy, put on his shoe covers and walked to the big tree where the dead man is bound.

This place was only ten meters from the pond, back against the pond, and tied up. There were many footprints around the body, shallow or deep, male and female, and some prints were covered. Han Bin crouched down and watched them carefully.

At this point, the corpse had already been deposited, with red fruits all over its body, swollen skin surface, its hands behind its back, in the shape of a semicircle, and obvious streaks on its forehead, neck, waist, and his legs, which must have been the result of a violent struggle.

Lu Wen put the rope in a plastic bag, ready to take it to the lab for further testing.

"Crack!"

Li Hui patted the neck: “Why are the mosquitoes in this place so big, there are so many during the day, and they are allowed to bite to death at night.”

“Mosquitoes breed on the surface of the water, they like dark and humid environments, and they breed very quickly,” Han Bin stood up and pointed to a small pond nearby: “You could say this is the best breeding ground for mosquitoes."

Wei Zimo approached, holding a notebook in his hand, and reported: "Captain Zheng, the transcript of the two witnesses' testimony has been completed. Allow me to introduce it to you."

Wei Zimo opened the notebook: “The informant is Lin Yang, a senior from Qingdao University, and he was dating his girlfriend Feng Xiao Li in the woods; Feng Xiao Li is a junior from Qingdao University and was the first to see the deceased."

"Then why did they only report it at 9:40 a.m., what did the two of them do during that time?" Li Hui asked.

“The two were so scared that they both forgot to call the police. They didn't remember calling the police until after they left the class," Wei Zimo didn't know whether to laugh or cry.

"Did they ever go around the corpse?" Zheng Kaixuan asked.

"Feng Xiao Li discovered the deceased by accident. According to her account, there were still five or six meters of the body. She was so scared that she ran away to another side and did not dare to go there to see it," Wei Zimo said.

"Apart from the two of them, was there anyone else who went near the body?" Han Bin asked.

"Nope."

Zheng Kaixuan pointed out the footprints on the ground: "Han Bin, there are a lot of footprints here, what do you think?"

"Many students like hanging out here, and the footprints are quite mixed, with overlaps and overlapping tracks. Detailed comparison and analysis of the footprint are needed, and it will be difficult to investigate," Han Bin said.

Zheng Kaixuan frowned: "Is there any clue to the identity of the suspect?"

"The suspect is naked, with no clothes or objects to prove his identity, only the rope to bind him and the towel for the gag. The clues we were able to get. Not much," Zhao Ying said.

"There are many onlookers among the students, show them the photo of the deceased and let them identify him, maybe someone can recognize the deceased," Sun Xiao Peng suggested.

"His face has been bitten by mosquitoes and is so swollen. Not to mention the onlookers' ability to recognize him, students might be scared upon seeing the photos of the corpse, and the consequences of panic on campus would be unimaginable," Zheng Kaixuan considered it more comprehensively.

"What Captain Zheng said makes sense. I suggest letting the teachers in the school identify it. The teachers are more convenient to manage and have a certain degree of organization to avoid unnecessary confusion," Han Bin said.

Wu Xia came with a box: "The preliminary autopsy at the scene has been completed."

"What was the cause of death?"

"The preliminary diagnosis was death from anaphylactic shock," Wu Xia said.

Zheng Kaixuan nodded, which was consistent with Han Bin's analysis, it seemed that the deceased had probably been tortured by mosquitoes.

"What about the hour of death?"

“Based on the stiffness of the corpse, he should have been dead for about ten hours, that is, around 1:00 a.m. last night,” As Wu Xia spoke, she gestured to signal to her assistant, Qiao Zi Ming, to put the corpse in a body bag.

This male corpse was about 1.8 meters tall and had a relatively strong build. Qiao Zi Ming couldn't move it alone. She shouted: "Brothers; help me."

Even though Sun Xiao Peng was tall, he dared not stand forward and grabbed his injured arm. Zhao Ming rolled up his sleeves and walked first; Wei Zimo was also shy and bold and walked second. The three worked together to put the corpse in the body bag and transported it to the corpse car.

Zheng Kaixuan didn't care about these trivial questions and kept asking: "Are there any defensive wounds on the body."

"That's exactly what I mean. The suspect has bruises on his chest, arms, waist, and legs, although they are not fatal, he should have been beaten," Wu Xia said.

Zhao Ying recalled for a moment: "I carefully observed the corpse and found no obvious scars on the surface of the corpse."

"These scars lasted more than 48 hours, and the symptoms were relieved a lot; and the mosquito bites absorbed the blood stasis, which can be relieved. The symptoms of bruising, associated with swelling of the body, the scars are unapparent," Wu Xia explained.

"The times of injury and death do not match," Zheng Kaixuan said.

"Mosquito torture does not kill you in a short time. There is no clear relationship between when you are bound and when you die. It is difficult to predict when the suspect committed the crime."

Han Bin touched his chin and continued to analyze: "I thought about a question, how did the suspect get into the woods?"

“Could it be the group of people who threatened him forced him into the woods and then tied him up,” Li Hui guessed.

"It's a university after all. Even if it's a public holiday, there will be students and guards on campus. If you do this, won't the suspect worry about being found out?" Han Bin asked rhetorically.

Zhao Ying said unconsciously: "The suspect should be a gang committing the crime, and the time of the crime is likely to be at night so that the deceased can be checked and the possibility of being discovered is not high."

"You're right, but the point of this is to do what?" Zheng Kaixuan held a cigarette but didn't light it:

"The suspect can easily kill the deceased if he can control him. Why take the risk of taking the deceased to the woods and torturing him with mosquitoes, which is a waste of time and a risky way to kill."

"Dear Bin has said before that this way of killing is more meaningful, and the suspect did not bury the body. Is this a provocation to the police?" Li Hui's brain hole opened wide.
