Chapter 8 Section 8

Gently pushing open the door of the conference room, Carrot saw a room full of black police uniforms, all of whom had higher police ranks than himself. He hurriedly found a chair against the wall, and before he sat down, he sat at the middle waist of the oval conference table. Deputy Director Wang of the Provincial Public Security Department caught sight of him and immediately greeted him, "Old Hu, sit in front!" He said as he pulled away a chair beside him. Only then did Carrot realize that the provincial and county-level maps on the wall were yellow and torn, with a layer of soil on them, and should have been replaced long ago; the conference table was also full of small holes burned by cigarette butts. There are also pictures drawn with ballpoint pens when people were bored in meetings in the past, and two thermos bottles with leaky bottoms were placed on them...

Carrot explained embarrassingly: "Director, our conditions here are poor..." Deputy Director Wang interrupted him with a wave of his hand, "Let's talk about the case first. The meeting has just started. Since you are the first policeman to arrive at the scene, please introduce the story in detail." In the conference room, apart from Carrot talking about the case, only the voices of everyone recording in their notebooks were heard. Only two people did not write: one is Deputy Director Wang, he is the highest leader here, and the accompanying secretary will record everything; the other is Chu Tianying, with a pen in his hand, and a notebook spread out on the table in front of him, It was blank.He stares intently at the carrot with the concentration of a deaf schoolteacher who reads lips.Li Kuohai who was beside him thought: This Chuchu is so bold, he doesn't remember anything, so isn't he afraid that Deputy Director Wang will blame him for not being professional?

But Deputy Director Wang obviously didn't care, and in the occasional glances he cast towards Chu Tianying, there was a hint of appreciation that couldn't be concealed. Every policeman in the provincial department knows that this appreciation is hard-won. A year ago, Chu Tianying was a detachment leader of the criminal police team in the provincial capital.At that time, a case occurred in the outskirts of the city. A family of four slept on the same bunk, and a fire suddenly caught in the house in the middle of the night.After investigation by the criminal police, it was judged as an accident.The incident did not happen within Chu Tianying's jurisdiction. However, at the one-week briefing on major and important cases held by the Provincial Public Security Department every Friday afternoon, Chu Tianying rushed to the scene when she heard about the case.

The scene of the crime was in ruins, exuding a strong smell of burning.The nearby residents are relatively poor, not to mention the houses next to each other, and there are many flammable rags piled up in each courtyard. Therefore, after the fire broke out, the neighbors fighting the fire saw that the fire was getting more and more fierce, and they were afraid that there would be a "burning camp" in the end. , So the house was almost demolished, leaving only a few wall panels. Chu Tianying walked around the house, but found nothing. When she came to the yard, she saw a plastic jug with a capacity of 20 liters in a corner of the yard. She unscrewed it and smelled it. There was still a little gasoline in it.I asked the director of the neighborhood committee and learned that the family didn't need gasoline in their lives, so his brows furrowed even tighter.

Someone patted on the shoulder, and when Chu Tianying turned around, it was a police chief in charge of investigating the case: "What are you doing here?" Chu Tianying replied: "I think this case is suspicious, so come and have a look." "Suspicion?" The other party raised his eyebrows in surprise, "What doubt?" "I can't figure it out. The whole family is sleeping in the house. Why did only one escape in the end when it caught fire? Did the others sleep so dead? Why can't a father just pull a child out?" In the process of handling a case, only by verifying every doubtful point can the occurrence of unjust, false and wrongly decided cases be avoided. Therefore, it is very common for the police to raise doubts about the case.But it just so happens that the police chief is the nephew of Deputy Director Wang, and he has always acted arrogantly: "I think you are just looking for trouble. It is written clearly in the autopsy report that the woman and the two children who were burned to death had blood in their trachea." There was inhalation of soot, which means that the three people still had signs of life when the fire broke out, and they were suffocated to death in the fire—the story of 'Zhang Ju Burning Pig', have you never heard of it?"

"Zhang Ju Roasted Pig" is a story recorded in the Song Dynasty forensic book "Zheyu Guijian".It is said that in ancient times, a fire broke out in Juzhang County, Zhejiang Province. The husband was burned to death. His brother thought that his sister-in-law killed his brother first and then set the fire, so he sued the county government with a piece of paper.Zhang Ju, the county magistrate, made an experiment for this purpose: he ordered to kill a pig first, then tie up the limbs of a live pig, and then throw the live pig and the dead pig into the fire at the same time.After the fire was extinguished, Zhang Ju asked people to check the two pigs. The mouth of the pig that was killed was clean, while the pig that was burned alive had its mouth open and there was a lot of soot in it.Let Wu Zuo go to see the "burned" husband again, and his mouth is clean... Finally, the victim's wife had to admit that she had killed her husband and then set fire to the house.

Living people have the ability to breathe. At the scene of a fire, it is inevitable to inhale the soot and charcoal in the flame into the respiratory tract.Therefore, "Zhang Ju Roasted Pig" has become an important reference for future generations to deal with such cases.At the scene of a fire, if soot, charcoal and other attachments are found in the mouth, nose, throat, trachea and bronchi of the deceased, it means that he was burned or suffocated to death, otherwise he will be killed first and then discarded at the fire scene of. This story is quite famous, of course Chu Tianying knows about it, but he has never been a book reader.

"The records in ancient books are not necessarily correct." He said bluntly, "The most valuable thing about Zhang Ju is not that he discovered the truth through roasting pigs, but the spirit of finding the truth about the murder case." The police chief was furious, and went directly to Deputy Chief Wang to file a complaint, accusing Chu Tianying of overreaching his post.After hearing this, Deputy Director Wang immediately called Chu Tianying to the office for a lecture. Chu Tianying stood upright like Bai Yang, without saying a word, after listening to Deputy Director Wang's training, he took out a note from his pocket and put it on the desk, "Vice Wang, this is my salary for this month The bill, a total of 2648 yuan - not as much as selling pancakes at the gate of our criminal police team. You ask me what I want to do? I don’t want to do anything, I just want to be a good policeman, not why, just because it’s like selling pancakes Ordinary people like Guozi work from dawn to dusk, grind flour and sell cakes, earn money penny by penny, pay taxes to the country, and then the country takes out their hard-earned money to pay me wages..."

Deputy Director Wang was stunned at that moment, and didn't speak for a while. Back in the team, Chu Tianying still felt very uncomfortable.Since returning from his training at the China Police University, he has developed a habit of flipping through the "Crime Scene Investigation Procedure" wrapped in the coloring pages of Jidi's comics whenever he feels uncomfortable, so that his colleagues make fun of him : "Is this book your bible?" How did they know the origin of this book - it was written by her, and he asked her for it on the day he graduated. "Give me your copy, no, no, no, I know it's sold in bookstores, but I want this one in your hand, maybe I'll never see you again in the future, keep it as a souvenir for me!"

So, she gave him the book she used as a textbook... Turning to the first page, he immediately saw her signature with a thin golden body, and a faint fragrance filled his lungs. He immediately forgot those troublesome things like drunk. Turn it over again and read this passage: "An excellent criminal forensic officer will never regard the crime scene as a plane, especially when the case takes place indoors, you actually walk into a hexahedron: the ceiling, the floor, and the four walls in the south, east, west, and north. surveyed every inch of the surface, and imagined myself looking down from the angle of the ceiling..."

Looking down from the ceiling angle... He stuffed a light blue bookmark into this page, closed the book, pondered for a moment, turned on the computer, and retrieved a set of pictures taken by the police after the fire from the intranet of the provincial department, one of which was from the criminal police station. On a ladder, three charred bodies rest on a bunk filmed from above. look down. Looking down from the ceiling. Although the murderer was cunning, he never thought that there was such a loophole. A smile condensed on the corner of Chu Tianying's mouth. Especially when the case happened indoors, you actually walked into a hexahedron... hexahedron. No, I have to go to the crime scene again. Chu Tianying rushed to the scene of the burned ruins again.This time, he walked into the "house" that had no roof, and instead of just walking around and coming out, he took a magnifying glass and looked at every inch of the wall panel, and finally found what he wanted. Mark of. Next, he applied to the provincial department to re-investigate the case, and he will preside over the suspect—the husband who narrowly escaped from the fire.Although Deputy Director Wang's nephew still obstructed it, no one expected that this time Deputy Director Wang not only approved it, but also attended Chu Tianying's interrogation in person. Afterwards, many criminal policemen present recalled that in that small interrogation room, there were actually two people being interrogated: one was the criminal suspect, and the other was Chu Tianying himself. Deputy Director Wang, who is well-known for his strict work requirements—in a sense, Chu Tianying bears no less psychological pressure than a criminal suspect. But Chu Tianying looked relaxed, "Please look at this photo taken from above at the scene. People often pay attention to the bed and the corpses on the bed, but what I want everyone to look carefully is the top of everyone's head in the photo." A group of police officers including Deputy Director Wang lowered their heads and carefully examined the photos in the file. "Everyone must have discovered it?" Chu Tianying explained, "The neighbors fighting the fire in the photos all have different degrees of curling on the top of their heads, and some are alopecia areata. That is when the sparks from the ceiling fell on their hair during the firefighting. It was formed by burning, but you—” He crossed his arm and pointed to the suspect sitting on a chair with his back against the wall, “In the photo, the top of your head is spotless. At the same time, other photos show that the hair on your forehead What’s going on? What could cause this phenomenon? There’s probably only one way—you pour the gasoline prepared in the yard on your wife and children, and then throw the matches Throw it in, and the moment the gasoline is ignited, flames will suddenly burst out, and you will be caught off guard from the front!" There was an astonished discussion immediately in the interrogation room. The suspect raised his eyelids, "Officer, this is just your speculation. You can't convict me of murder just because my eyebrows are singed? You have to produce convincing evidence." Suddenly quieted down, all eyes were on Chu Tianying. Chu Tianying sneered. Especially when the case happened indoors, you actually walked into a hexahedron... "The indoor crime scene is a hexahedron, including the ceiling, the floor, and the four walls in the southeast, north, and west—this is what Mr. Liu Simiao, a top expert in criminal forensics in China, repeatedly warned us when I was studying at the China Police University." Mentioned her When he named the name, a warm current surged in his heart, he had to pause, and then continued, "So, when I conducted the second survey of the fire scene, I paid special attention to checking the wall, and found A strange trace... However, before mentioning this trace, please take a look at the photo again: the bed at the scene of the fire is a bunk, extending from east to west, all leaning against the wall. The order in which the whole family sleeps is from west to The east numbers are: wife (close to the west wall, facing west), eldest daughter (facing east), youngest daughter (facing east) and husband." "Don't you think it's strange?" Seeing everyone's blank faces, Chu Tianying explained, "In life, mothers seldom sleep with their backs to their children, and they often place the youngest child closest to them. The place where the dead body is located—so the photo at the scene that reflected the position of the corpse made me feel abnormal, so I formed a bold idea: Maybe the hostess is indeed used to sleeping facing the west, but she was originally facing the child, in other words, this The order in which family members are arranged when sleeping is supposed to be from west to east: husband, eldest daughter (facing east), youngest daughter (facing east), wife (facing west). Once a fire broke out, the husband whose sleeping position was farthest from the door escaped, but the others were burned to death, which easily aroused the suspicion of the police. Therefore, after the suspect knocked his wife into a coma, he moved her to a place close to the west wall. In this way, people who don't know will think that the husband slept in the place closest to the door, and it is not surprising that he is the only survivor because he is close to the door. "I just said that the husband put his wife into a 'coma' - which explains why the three deceased had inhaled a lot of soot in their trachea. I am familiar with the story of 'Zhang Ju Roasted Pig', but I also remember another case: one In 2010, a fire broke out in a seven-storey residential building in the southeast of Paris, France, killing 17 people and injuring more than 30. The investigation results showed that most of the victims had soot in their respiratory tracts, indicating that they died of suffocation in their sleep. Not burnt to death. So I figured if the wife and two kids were alive and breathing but unconscious and incapacitated at the time of the fire, we'd still find soot in their airways afterwards . "The murderer decided to kill three people at a time. He must have thought carefully. He would not just expect them to fall asleep, and would not escape from the fire after the fire. It would be more appropriate to make them unconscious in advance. And it is not easy to make the victim unconscious. The method of autopsy discovery, I think, should be to stuff the head with something like a pillow to suffocate it, and then remove the pillow after the victim falls into a coma, so that it can still breathe, and then set fire to it." Chu Tianying analyzed "A wife who is awake will certainly not allow the murderer to move herself behind the west wall to faint, so I speculate that the wife should lie down against the east wall as usual, and the murderer knocked her out on the spot. Then move to the west wall. According to this train of thought, I found the one I just mentioned on the east wall—the strange trace.” He took out some enlarged photos and showed them to the policemen present, "Look, these are the scratches I found on the east wall of the whole shop. Deep in the scratches, I extracted skin fragments, which were analyzed by DNA. And basal cell tests showed it was left by the dead hostess on the night of the fire." The suspect was trembling, and suddenly he raised his head, fierce like a wolf forced to the edge of a cliff, "Your evidence can only prove that my wife once leaned against the east wall when she slept, scratched the wall, and can Prove what?" In an instant, the interrogation room fell into dead silence again, and all eyes focused on Chu Tianying again, among which Deputy Director Wang was the most fierce. Chu Tianying smiled. He walked up to the criminal suspect, bent down, looked at him majesticly, and said word by word: "I forgot to tell you, from the depth of the scratches, apart from extracting your wife Some blood components were also extracted from the skin scraps. The test showed that the dna was exactly the same as yours. I think this is probably because she scratched you with her nails when you covered her face with a pillow, and then During the struggle, you scratched the wall. You thought you could burn the evidence of your blood left between her nails with a fire, but God knows, the wall was not destroyed by the fire. The scratches are like iron proof-you bastard is the real murderer!" The suspect conceded - he had a mistress in the country and wanted her to give him a boy, so he murdered his wife and two daughters. The case was finally solved, Chu Tianying breathed a sigh of relief, but after thinking about it, he had completely offended Deputy Director Wang, not to mention that he might have to wear small shoes often in the future. Two said.For this reason, he specifically found a college classmate in a securities company, and planned to find a job with him after he was laid off.Unexpectedly, Xiao Xie didn't wait, but what he waited for was a letter of appointment with the big red seal of the Provincial Department. He was appointed as the Director of the Criminal Investigation Department of the Provincial Public Security Department. Next, I heard from a friend in the provincial department that Deputy Director Wang pressed his salary slip under the glass plate of his desk. After becoming the director of the Criminal Investigation Department, Deputy Director Wang never said a word to Chu Tianying, even if they bumped into each other in the elevator, they just nodded. The first thing that comes to mind must be Chu Tianying. When encountering a major case that is difficult to solve, he must be ordered to be responsible for solving it. All this makes Chu Tianying feel very, very warm. At this moment, Chu Tianying, who was listening intently to Carrot's case, was not too lazy to write, but remembered the words in "Crime Scene Investigation Procedure"—— The first officer to arrive at the crime scene should be questioned by other police officers in an interrogative manner: How did he find the scene?What did he do when he arrived at the scene?Who did he meet?What happened before the other detectives arrived... At this stage, the important thing is to listen, to listen to every word with doubts. Listen questioningly to every word. Li Kuohai, who was sitting next to Chu Tianying, kept recording, and the tip of the pen never left the notebook, leaving black marks like spiders crawling on it: At 10:14, Xiao Wang, an assistant policeman on duty at Hulingzi Township Police Station, received a call from Zhang Dashan; At 10:15, the head of the township police station, Hu Weidong, dispatched the police and rushed to the lakeside building; At 10:30, Hu Weidong drove to the lakeside building and saw Chen Shaoling at the door. After entering the door, he found six dead bodies in the KTV private room, and then Zhang Dashan rushed to the private room; At 10:40, Hu Weidong exited the lakeside building and called Xiao Wang, the assistant policeman on duty, asking him to call all the policemen in the station to rush to the lakeside building, and at the same time ask the county public security bureau for help... "Wait a minute." Chu Tianying suddenly raised his hand, indicating that there was a problem, which startled Li Kuohai.Carrot also quickly stopped talking, and turned to Chu Tianying. "I have a question. At 10:14, the police assistant Xiao Wang received a call from Zhang Dashan. What are the details of the call?" Carrots are a little nervous. He collected himself, thought about this question that didn't need to be thought deeply, and then replied: "Zhang Dashan said 'something happened to the lakeside building', let us go there quickly. He didn't go into the lakeside building at that time, Just because I almost bumped into the bloody white woman on the road, she looked like a tourist, so I drove her to the lakeside building, and saw that something was wrong inside—the owner of the lakeside building, Li Dazui, never turned off the lights all night— That's why he called the police. The relationship between Zhang Dashan and Li Dazui has always been relatively good. After calling the police, he still felt uneasy, so he asked Chen Shaoling to stay outside and wait for the police, and then went in to see the situation. The doors on the first floor were locked After that, he went up to the second floor and opened the guest rooms one by one to check until I rushed over." Chu Tianying nodded, "Please briefly introduce Li Dazui's situation. Why haven't you found this person and other employees of the Lakeside Building?" "Li Dazui, it turned out that in our township, he was a 'capable man' who did a good job in farm work, carpentry work, and bricklayer work. He was very shrewd and kind. This lakeside building opened in the township, and the business is good. On normal days, he, his wife, and his nephew are the only three people in charge of the store. If they are too busy, they temporarily find a young man from the township to do part-time work. I came here a few days ago Once, I randomly checked the ID card registration status of passengers, and he said that the wind has been strong these days, so I don’t want to come here. Now where is he, his wife, and his nephew... I really don’t know.” In my country's public security system, although the police station is the size of a sesame seed, it is the "base" of the entire public security work.To investigate and solve a case, we must first rely on the security police of the police station to grasp the situation at ordinary times, that is, the so-called "four knowledges" to know the names, nicknames, addresses, physical characteristics and "big knowledge" of key populations and marginal populations within the scope of their duties. Familiarity" The familiarity rate of places with high incidence of public security accidents in the jurisdiction must be 100%.Once a case occurs, if you ask which family and which person in the area are more suspicious, the police at the police station must be able to tell the truth immediately. Right now there are six corpses lying in the lakeside building. As the director of the township police station, Luo Luo doesn't know the whereabouts of the business owner. Anyway, it is a very serious matter.Li Kuohai couldn't sit still anymore. After all, Hulingzi Township Police Station is within his direct jurisdiction. He was about to stand up and make a self-criticism, but Chu Tianying had no intention of pursuing it. He raised his hand at Carrot, "Old Hu, you continue." In fact, there is still a lump in the heart of the carrot. Last night, when he entered the lakeside building, he yelled Dashanzi twice at the front of the lobby, but there was no one answering in the deadly silence of the building. He just showed up and said that he had been on the second floor—what was he doing in the dark on the second floor at that time, Carrot knew it well, but he didn't want to make it public.Compared with the current case, what Zhang Dashan committed was a small case, and Luo Luo didn't want to make another "little mistake" to send the child to prison again.He thought, wait for Da Shanzi to finish his investigation later, and scold him alone... Carrot quickly finished his statement, and most of the police officers still had to "digest and digest" without asking questions.Chu Tianying cast her eyes on Deputy Director Wang, "Let me make a preliminary investigation report on the crime scene." Deputy Director Wang nodded. There was a rustling sound in the conference room.The police officers all straightened up, and their drooping eyelids were all wide open. Listening to the preliminary investigation report is one of the most important tasks in the early stage of criminal investigation. It can be said that it is the first contest between the police and criminals with the wisdom of the crowd.Through the preliminary understanding of the crime scene, make a judgment on the nature of the case, outline the criminal process, analyze a large number of physical evidence one by one, make a simple profile of the suspect, and the most important thing is to finally form a resolution: determine the entire case direction of investigation. There is a word called "tree target". When criminal policemen say "tree target", it means that they are going to make a preliminary investigation report. quasi-target. When listening to the initial investigation report, if you don't say a word, it is often considered a sign of incompetence. Chu Tianying held two calendars with beauties in swimsuits on the front, walked to the wall, turned them over, and pressed them against the wall with thumbtacks. On the smooth white background on the back of the calendar paper, he drew two pictures with a black carbon pen: one is the floor plan of the lakeside building; the other is the floor plan of the ktv room, with green "y" on it The location of each deceased is marked, the bloodstains are marked in red, and some physical evidence that may have important suspicious points is marked in yellow. "There are no slides, so I have to make do with it." Chu Tianying said, using a telescopic antenna temporarily removed from the semiconductor, he pointed and drew while telling everyone. "We numbered the deceased." He pointed to the floor plan of the KTV private room and said, "Corpse No. 1, an old man, was lying down next to the door of the private room. Shock, a sharp knife was extracted next to his corpse. By comparing the blade and the wound, it can be confirmed that this knife is the murder weapon. The palmprint and fingerprints of corpse No. 6 were left on the handle—corpse No. 6 The details of the situation, I will talk about it later. "Corpse No. 2, female, about forty years old, in the form of death sitting on the ground with her back against the wall, the cause of death is unknown..." "Huh?" Deputy Director Wang frowned. Chu Tianying explained: "The corner of her mouth was bleeding, but the forensic doctor is still unable to confirm the cause of her death. She only suspects poisoning." Deputy Director Wang nodded, motioning for him to continue. "Corpse No. 3, female, in her twenties, was lying on her back on the sofa on the north wall, bleeding from the corner of her mouth, the cause of death is unknown. "Corpse No. 4, male, estimated to be over 40 years old, lying on his back on the floor near Corpse No. 3, bleeding from the corner of his mouth, the cause of death is unknown. "Corpse No. 5, male, about 30 years old, lying curled up behind the door of the playback control room at the innermost side of the private room, bleeding from the corner of the mouth, the cause of death is unknown." "Why are there so many people whose causes of death are unknown?" Deputy Director Wang muttered. Chu Tianying immediately faced him and stood at attention. The forensic doctor of the County Public Security Bureau couldn't sit still, and slowly stood up, with a look of shame on his face, "Deputy Wang, our technology still needs to be improved..." Deputy Director Wang waved him to sit down, and then turned his gaze to Chu Tianying again. "The four corpses 2, 3, 4, and 5 should belong to the same cause of death, such as poisoning, but further forensic examination is needed to confirm." Chu Tianying said, "Corpse No. 6, male, died with his limbs spread out. Lying prone on the side of the coffee table. The cause of death was severe open brain injury caused by blunt force blow to the head. There was a broken glass ashtray next to him. According to preliminary judgment, this was the murder weapon that caused his death. But in this ashtray On the tank, we didn't get any fingerprints." Next is the analysis of the physical evidence. Generally speaking, even in the most common murder case, there are dozens of physical evidence including the murder weapon, hair, fingerprints, and bloodstains.And there may be hundreds of pieces of physical evidence in a particularly serious murder case.It is the job of forensics personnel to analyze its components one by one, whether it contains trace evidence, and so on.In the initial investigation report stage, what the main reporter needs to do is to introduce some key physical evidence, and point out which physical evidence has greater doubts or has greater significance for the detection of the case. A criminal policeman moved a transparent plastic basket to the table. Putting on rubber gloves, Chu Tianying took out evidence packed in plastic bags or paper bags from the plastic basket and showed it to everyone, while explaining and analyzing: "These are two microphones, and there are many messy spots on the microphones. Fingerprints, one was left on the sofa where corpse No. 3 was lying on its back, and the other rolled down on the floor; this was one of the beer bottles found at the scene, a total of two boxes of 24 bottles, all of which were produced in the province with the brand "Happy Cool" , Twelve bottles have been emptied, four bottles have been half drunk, and eight bottles have not been opened; this is the 'Five Elements Yin and Yang Mirror'..." "What?" Deputy Director Wang asked, staring at the jade-like object in his hand. Chu Tianying said embarrassingly: "A medical device, it is said that it can cure diseases through irradiation... I don't know much about it." Someone asked, "Will this thing kill people? Like radiation or something." Most of the people at the venue showed a look of sudden realization, and a whisper sounded: "Can this weird thing kill people?" "I can't say for sure, but the current medical equipment has killed and injured many people." "Then the cause of death of corpses 2, 3, 4, and 5 is clear..." At this time, a plump forensic technician wearing black-rimmed glasses cleared his throat. Everyone knew that he was about to speak, so they immediately fell silent. "This still needs to be tested in the next step." Fat Xingji's words were very short, and everyone looked at him eagerly, thinking he would say something else, but there was no movement after waiting for a long time.Everyone had a look of disappointment on their faces, as if they were starving to death and finally saw a dish served on the table, but it was immediately removed. Chu Tianying continued to explain and analyze other physical evidence: "This is the crocodile leather business card holder found in the pocket of No. The true identity of Corpse No. 4." "Jianyi Health Products Company?" Deputy Director Wang interrupted, "It's a big company, a listed company." "Yes!" Chu Tianying said, "I checked it online, and it is currently the largest health care product company in the province." "The 'Five Elements Yin and Yang Mirror' is produced by their company." Carrot also interjected, "Every time the advertisement on TV, the last sentence is - Jianyi products, health first!" "What about the identities of the other victims?" someone asked. "From corpse No. 5, a box of business cards was found with the words 'Jianyi Health Products Company Office Director Gong Jing' written on it. The identities of the other corpses have not yet been confirmed, but they are probably related to Jianyi Health Products Company." Chu Tianying Said, "At present, our investigation is mainly concentrated on the private rooms on the first floor, and before the incident, these people lived in the guest rooms on the second floor. The identity of each person can only be confirmed after a comprehensive inspection of their residences. But from the clothes From the looks of it, the deceased should not be from Hulingzi Township." "I'm sure of that." Carrot nodded heavily. When talking about the blood evidence, Chu Tianying focused on the blood fingerprints found on the inside handle of the private room door: "After identification, these are the fingerprints of the No. 6 deceased, but the blood belongs to the No. 1 deceased. It is understandable." Well, after No. 6 killed No. 1, he pulled the doorknob with No. 1's blood-stained hand..." "Then who killed No. 6 himself?" A criminal policeman asked, "He definitely didn't commit suicide, because he couldn't hit the back of his head with an ashtray." "He was killed by No. 7!" Li Kuohai said gruffly. Where did the number 7 come from? All the people in the venue stared at each other suddenly.Li Kuohai also knew that his words were abrupt: "No. 7—this is the code name I gave to the escaped murderer." Someone sighed. Li Kuohai tilted his head and saw that it was a carrot, "Old Hu, why are you sighing? Am I wrong?" Carrot smiled wryly, "Ju Li, when I told the story of the case just now, there was one thing that I didn't mention in detail - I pushed the door of the KTV private room, but didn't push it open, and then I slammed it in. Later, I found out that the door It's locked from the inside." "Huh?" A surprised voice sounded. Chu Tianying's expression was very calm, "Criminal technology!" He tapped the table lightly with his index finger, prompting the criminal technicians to speak. The chubby criminal technician was peeking at the text message, quickly closed the phone, opened the notebook in front of him, and said in a voice as rigid as his black-rimmed glasses: "The door locks in the ktv rooms are mortise locks, and the bolts are single. As for the oblique bolt, after careful inspection, it can be confirmed that the door lock was knocked open by an external force, and before the knock was opened, the deadbolt remained intact and inserted." "Tell me the key point: is the door locked from the inside, or from the outside?" Chu Tianying chased. "It's locked from the inside. The lock is a one-sided lock that can only be opened from the inside. There is no lock hole on the outside of the door." "How is this possible! Did you make a mistake?" Li Kuohai widened his eyes, "How did the murderer leave the private room? The windows of the private room were all locked from the inside, and we opened the ventilation channel on the ceiling to see There is a thick layer of dust, without any trace." "The results of the on-site investigation show that the No. 7 you mentioned should not exist." Chu Tianying touched his chin and thought for a moment, then said slowly, "My analysis shows that the case should be like this: among the six people in the room , one of them was an accomplice with No. 6, and I will call him x for the time being. They locked the door of the private room at the beginning, showing their killing intent. When No. 1 wanted to escape from the door, he was killed by No. 6. There are two possibilities: One is that x kills number 6 first, and then forces the remaining three people to commit suicide together with him; die, and then commit suicide." "Is it possible that number 6 poisoned everyone first, and when number 1 realized that he wanted to escape, he was chased and killed by number 6, and then the rest of the people smashed to death number 6 together, and then died of the poison?" Someone asked . Chu Tianying thought for a while and said: "There is no trace of other people uniting to fight No. 6 at the scene. Besides, no matter how poisonous the poison is, it will not cause several people to die at the same time. They fled in the direction of the door? But the scene shows that they died scattered and scattered—in any case, all crimes were given and received among the six people in this room, Only in this way will the 'closed room state' of the scene be presented." If this is the case, then the rest of the criminal investigation work can be temporarily declared over: anyway, the murderer and the victim died together, and there is no need to continue the investigation.Someone in the conference room let out a sigh of relief. Li Kuohai seemed to be choking, his eyes were blank, he was stunned for a while, and suddenly said loudly: "I don't care whether the secret room is a secret room or not! I dare say that there is indeed No. 7, the No. 6 he killed, and then from Escaped in that private room full of dead bodies!" In the provincial public security system, Li Kuohai is known for his tenacity.When chasing the murderer, he dared to chase for five miles with his heart that had just been braced. He also handled the case with this kind of energy that he would never turn when he was sure, which was loved and respected, and sometimes it was a headache.Therefore, someone at the venue made fun of him: "Then tell me, who is this No. 7 who escaped from the private room with the doors and windows locked?" There was a lot of laughter. Li Kuohai didn't smile, his face was flushed, and he raised his voice: "Of course I know who No. 7 is!" The laughter stopped abruptly, and the policemen at the venue looked at each other in blank dismay. "Ju Li." Chu Tianying put both palms on the table, stared into his eyes, and asked seriously, "Who is No. 7 you are talking about?" Li Kuohai showed no fear, "It's that woman in white who is covered in blood!"
