In the past detection process, Bao Zhan has repeatedly used simulations and experiments of criminal behavior to grasp the psychology of the murderer, which has played some role in the detection. Why did the murderer tie the victim up with a fishing line, and why did he hold the victim in front of him?
Midnight street crawl?
Only a madman knows a madman best.
The old criminal policeman who likes fishing bought several types of fishing lines from Zhong District, Jining City, including a 500-meter powerful marlin line, a PE multicolored eight-braided fishing line, and a raw silk sea fishing anti-bite line imported from Japan. Bao Zhan chose it.
What's more, it is a sea fishing line with super strong pulling force and good flexibility. Not to mention the constant bite of human teeth, it is difficult for even sharks to bite it. This kind of sea fishing line can catch sharks and even pull cars.
Bao Zhan was sitting on a chair, holding a fishing rod, staring at the fishing line in trance, as if there was something hidden at the end of the fishing line.
Bao Zhan said: "Are you ready?"
Dai Viet said: "Let's start."
Bao Zhan said: "If you don't want to try, you can give up now."
Dai Viet said: "It's two thousand yuan!"
Sun Dayue pulled out a piece of fishing line, crumpled it into a ball, and stuffed it into his mouth without thinking. The fishing line seemed to be a mess. He chewed it a few times out of habit, frowned, and swallowed it several times before swallowing the fish.
Eat the thread bit by bit into your stomach.
Bao Zhan said: "Just shake your head and give it a try."
Da Yue shook his head and said, "I feel a little uncomfortable in my stomach and want to vomit."
Bao Zhan said: "Don't vomit, you have to poop out tomorrow."
Dai Viet said: "I'm constipated, I guess I'll have to wait a few days."
Sun Dayue was carrying a fishing rod with a fishing line in his mouth. He went home to cook for his paralyzed old mother. When the neighbors in the community saw him, they were surprised at first, and then burst into laughter. Dayue
Just after leaving, Xiao Ruoli carried her schoolbag and went to school. It happened to be a big weekend once a month and she did not go to class. In order to avoid exposing her identity, she was not allowed to come to the Public Security Bureau while she was undercover. However, Xiao Ruoli was worried about Dai Viet's safety.
I want to visit Sun Dayue.
Bao Zhan said: "What's the use of going?"
Xiao Ruoli said: "Forensic doctors are at least doctors. I'm going to see if Uncle Dai Viet is okay."
Bao Zhan said: "I think it's not life-threatening, don't worry."
Xiao Ruoli said: "You know, he swallowed a piece of fishing line into his stomach...why don't you try it."
Bao Zhan said: "If no one is willing to do it, I will definitely do it."
Sun Dayue's home is in the Xianghe Home Community in the west of the county. There are affordable housing here, and the buyers are all low-income people.
When Bao Zhan and Xiao Ruoli knocked on the door, Sun Dayue was about to
While cooking, the fishing line connected to his body made it a bit difficult for him to do whatever he did, so he needed to be careful at all times. Dai Yue's mother was sitting in a wheelchair, warmly welcoming the arrival of Bao Zhan and Xiao Ruoli. Dai Yue was a little embarrassed, and the house
The furniture inside is old and the sofa is piled with clothes, making it look very shabby.
Bao Zhan helped wash the vegetables, and Xiao Ruoli talked to Dayue's mother. This old man in a wheelchair reminded Bao Zhan of Professor Liang.
Dai Viet's mother said: "My Dai Viet had a blind date two days ago, but what happened after that, I didn't tell him even if I asked him."
Xiao Ruoli said: "I've seen that sister. She works in a TV station. She's so pretty."
Dai Viet's mother said: "Pretty girls don't look down on Dai Viet."
Xiao Ruoli said: "Uncle Dai Yue is very handsome. He can be considered a talented person."
Dai Viet’s mother said: “The main reason is that we don’t like our family.”
Xiao Ruoli said: "It will always get better."
Dai Viet's mother said: "Unless I die, no girl would dare to marry me because of my illness. If I hadn't dragged Dai Viet down, Dai Viet wouldn't have been a bachelor in his thirties. Alas..."
Dayue's mother stopped talking, and Xiao Ruoli couldn't do anything but stayed with her quietly.
When Xiao Ruoli was a child, there was a lonely old woman in the neighbor's house. Her husband had just died. She sat in the yard and cried every day. When Xiao Ruoli came back from kindergarten every day, he would sit on the old woman's lap and cry with her for a while.
When eating, Sun Dayue felt extremely uncomfortable because there was a fishing line in his mouth. Every time he took a bite, he felt slightly nauseous. Every time he swallowed, a piece of the fishing line would accompany the food. He couldn't help but
Want to vomit.
After finishing the meal, Da Yue was sweating profusely and his body looked weak. He collapsed on the sofa.
Dai Viet said that he had caught drug dealers hiding drugs in their bodies before. Those drug dealers used a more subtle way of transporting drugs. They put the drugs in condoms, then swallowed them, and then excreted them when they arrived at the destination. Some drug dealers can hide them.
The drug can range from 500 to 1,500 grams. A few hundred grams of the drug can stay in a drug dealer's body for two or three days, during which the drug dealer basically does not eat.
Xiao Ruoli explained in detail the entire process of fishing line mixed with food passing through the body and finally being excreted.
Starting from the mouth, with the help of teeth and saliva, the food is chewed into small pieces, mixed with the ball of fish line, and pushed down by the peristalsis of the esophagus as soon as it enters the esophagus. Peristalsis is a form of movement of the smooth muscles of the digestive tract.
Under the joint control of the sympathetic nerve, vagus nerve and intestinal nervous system, the circular smooth muscle contracts from near to far, forming a forward-propelling wave.
After entering the stomach, the fish thread food mass mixes with the digestive juice and enzymes in the stomach. After regular turning and stirring, the food finally becomes a thick porridge, which is called chyme. The fish thread will not be digested.
fall off, pass together with chyme
The narrow opening at the end of the stomach, the pylorus, leads to the next organ, the small intestine.
The line and digested food then exit the small intestine and enter the large intestine through the ileocecal valve, which prevents food from refluxing.
The large intestine is home to a large number of bacteria, led by E. coli. The large intestine uses its unique "bag-like back-and-forth motion" to rub the food residue and absorb the water in it, drying it into feces.
The large intestine pushes feces into the sigmoid colon in sections through peristalsis.
When the feces in the sigmoid colon accumulates to a certain extent, it is pushed into the rectum by peristalsis, causing a defecation reflex and letting the brain feel the urge to defecate. The urge to defecate causes the contraction of the colorectum and the relaxation of the anal sphincter, which in conjunction with the contraction of the abdominal muscles leads to an increase in intra-abdominal pressure, wrapping the
The feces of the fishing line will be excreted from the body.
Xiao Ruoli said: "It will be particularly painful when excreting. You must know that the fishing line will pull many organs, such as the throat, esophagus, stomach, pylorus, small intestine, ileocecal valve, large intestine, rectum... it will affect the whole body.
."
Dai Viet said: "I feel it now. Although this kind of pain is not fatal, it can definitely be regarded as torture."
Bao Zhan said: "It is basically certain that the suspect's motive was revenge. What did those girls do?"
Xiao Ruoli said: "I heard one thing. Wang Xiaoshou is indeed very suspicious. He has chased two of the four missing girls."
Wang Xiaoshou is an annoying guy. He loves to surf the Internet. In Tieba, and in various barrages on Douyu, Huya, and Bilibili, he repeatedly says: Whoever can type the word "taotie" is the one I think he is.
Dad. He is a troll on the Internet and will curse people for no reason.
In the class WeChat group, Wang Xiaoshou said: "Girls don't like me because I'm stupid and lazy."
Xu Mengmeng said: "If you are a stupid and lazy dog, girls will definitely fall in love with you."
Just because of this sentence, Wang Xiaoshou fell in love with Xu Mengmeng, because no one in the class group paid attention to him at all.
Xiao Ruoli found out that Wang Xiaoshou soon fell in love with Xu Mengmeng. Wang Xiaoshou felt ashamed and abandoned her to pursue Song Qiangwei instead.
Wang Xiaoshou invited Song Qiangwei to eat KFC. Wang Xiaoshou went to the service counter and ordered Coke, burgers and chicken wings, and the two chatted while eating.
Song Qiangwei said: "Why are you chasing me?"
Wang Xiaoshou said: "There are so many people chasing you, why don't you miss me? Just give me a chance."
Song Qiangwei said: "Is it because several people in the school say that I am... very casual? Have you heard about it?"
Wang Xiaoshou said: "I didn't say you were a random girl."
Song Qiangwei laughed: "I like handsome guys."
When Song Qiangwei was full, she wiped her mouth with a napkin and walked away.
