"Just from such a door and such a storage room, can we conclude that this case was a homicide? Isn't this too hasty? At the very least, you should provide some evidence so that someone can pass through this storage room. Is it possible to enter this villa? As far as I know, when the local police station arrived at the scene, all the doors of the villa were locked, including the courtyard door, the villa door, and even the one you just mentioned. The basement doors are all locked, so how do you explain this? " This time it was Jing Nan who asked the question. He didn't usually talk to Li Xiangdong very often, but almost everyone in the bureau did. You know, the first brother of the city bureau is so fond of Li Xiangdong, a newborn calf, that it can even be said that he almost treats him as a godson. Several times, this kid got into trouble. In the end, even the first brother from the provincial department wanted to deal with him. In the end, it was the first brother from the municipal bureau who saved him despite the pressure. Now the first brother of the city bureau seems to be questioning Li Xiangdong face to face, but in fact, everyone who understands knows that this is a kind of love for Li Xiangdong, for the purpose of protecting him, and based on the starting point of an old criminal investigator. He offers guidance and protection. Questions from well-intentioned people are always much kinder and easier to answer than questions from people who have evil intentions towards you. This is indeed a key point. The biggest headache for everyone before was this case. Although there are many doubts, the key is that if you want to classify this case as a homicide, then you have to face the first problem, then It is the sealed environment of the crime scene. This is exactly the kind of secret room murder case that is often encountered in Conan or Kindaichi Incident. If an outsider committed the crime, how was the sealed environment at this site created? Even though the door to the basement does not have an alarm system connected to the entire room, when the police arrived, the door was locked, and more importantly, it was locked. This door is not an ordinary cheap floor-to-ceiling glass sliding door. This door is a specially customized glass sliding door. The brand is a well-known domestic manufacturer and the materials used are absolutely reliable. The frame is not ordinary plastic steel, but an aluminum-clad wooden structure. This frame can ensure long-term use without deformation. If it is a plastic steel frame, it will definitely deform after a few years of use. . And this kind of frame is guaranteed not to deform, so it is not so easy to pry the door lock from the outside. And even if you use a credit card or other lock picking tool, if you want to pick the door lock, you will always leave marks on the door frame and the lock. But now the news coming from the Trace Inspection Department is that there are no obvious signs of prying on the door lock. In this case, Jing Nan¡¯s question is very crucial. But the storage room in the basement you mentioned is very suspicious. The room is very clean, there are traces of being wiped on the door handle, and even the floor leading upstairs has traces of being wiped. But there is a crucial question. Even if there are indeed traces of wiping on these paths, how did the suspect enter the scene? ¡°This door was well locked when the police came, and there were no signs of being picked open on the lock. So how did the suspect enter the scene? And how did you leave after committing the crime? The most important thing is how did he lock the door when he left? These puzzles all require you, Li Xiangdong, to solve them. Anyway, it was you who raised the doubts. And you said the person was killed by him, so of course you should be the one to find out the answer to the key doubts about this secret room murder case. Jingnan¡¯s question hits the nail on the head. Li Xiangdong mentioned a few doubtful points before. When everyone thought about it, it seemed that this was the case. Hearing what Li Xiangdong said, it is indeed possible that Pan Yuanhai died of homicide. But now that Director Jing said this, everyone suddenly remembered that the key to this case, if this is a homicide case, this is a secret room murder case! Even if the doors and windows in the basement are not connected to the electronic alarm system, it seems not that easy for an outsider to enter and exit the site freely, right? How was this secret room made? How did the suspect get in? You really have to give a reasonable explanation! At this time, almost everyone in the entire conference room focused their attention on Li Xiangdong. Everyone wanted to see what kind of surprise this magical boy could bring to everyone this time. Originally, some people wanted to see him make a fool of himself. After all, it is not that easy to solve the secret room problem. If this guy was not prepared, he would have beenWe're in a good position. But Li Xiangdong once again disappointed those guys with dark hearts. At this time, this guy's smile was actually full of confidence. "Haha, okay, let me show you how to enter and exit this scene and create an environment for killing people in a secret room." After saying that, he waved his hand, and soon there were several teammates from the criminal police team. A glass sliding door was carried in. Before Li Xiangdong entered the conference room, he specifically asked several teammates in the team to help find it. Just some time ago, the Criminal Investigation Team detected a case of building materials theft. A lot of stolen goods were recovered from the den of thieves, including various steel bars and plastic steel doors and windows. Among them were several high-end plastic steel doors and windows, such as It is similar to the one used by Pan Yuanhai. Although it is not as good as Pan Yuanhai's, it is not much worse. At the same time, Li Xiangdong escaped from his pocket with a thin roll of fishing line, which he happened to buy on his way back. He asked two teammates to hold the door, then tied the buckle inside the door with fishing line, then closed and locked the door, and then reached out and pulled half of the fishing line leaking out of the door, almost without any effort. With some strength, the locked buckle was pulled open from the outside, and then the sliding door was opened with a slight pull on the fishing line. After that, close the sliding door, then pull the buckle down, and the buckle is easily locked from the outside. And as long as the fishing line tied to the buckle uses a live buckle method, then as long as you use a little more force, you can lock the buckle and pull the line buckle open at the same time, and then With a slight pull from the outside, the fishing line is pulled out directly, and then a sealed on-site environment is completed! With Li Xiangdong¡¯s demonstration, almost everyone at the scene was stunned. A sealed scene that was originally thought to be more difficult than the sky could be cracked so easily? This guy can open and close the door easily with just a piece of fishing line without any effort at all? The security measures in Qingshan Yunhai Community are indeed very strict, but it is not an impossible task to enter the community. And although the door of Pan Yuanhai's yard is locked, it is not impossible to get in by climbing over the wall. It's difficult, and the courtyard wall of his house is not like the courtyard wall of the community, which has some surveillance cameras installed. And their family¡¯s last line of defense, the problem of access to the villa, was solved so easily by Li Xiangdong. As a result, the possibility of homicide in this case suddenly increased! ¡°If before, many people were still watching Li Xiangdong¡¯s jokes, but now when they see that he can easily crack the secret room environment, everyone no longer regards this case as an ordinary accident. The police are always the most suspicious group, but now many people have begun to officially regard this case as a criminal case of homicide. "Now I have another question!" Jing Nan asked again at this time. The scene was already becoming more and more serious. At this moment, it became even more silent, as if a pin dropped to the ground. Everyone It was so quiet that everyone could hear it. Li Xiangdong nodded, indicating that he was ready to accept the move. "You have just cracked the secret room environment. You cracked it very beautifully. However, the key to the problem lies in the step of entering for the first time. Let's take a look. First, you need to make a buckle out of your fishing line and tie it to the door. But when the suspect came, the door was locked. How could he tie the fishing line to the bayonet when the door was locked? " Jing Nan asked the people at the scene. Only then did I realize that this was indeed such a problem. It was quite novel to watch the boy open the door with a fishing line before, but I completely forgot about it. What if the door is locked when the criminal suspect comes? But at this moment, Li Xiangdong suddenly gave a mean smile. "Who said that the door was locked when the criminal suspect came? And who said that this case was committed by one person?" "What!" As soon as Li Xiangdong said these words, it was almost like saying A bombshell was dropped at the scene. Even Jing Nan's expression suddenly changed at this time, and several leaders immediately started to take action. This guy is so brave. His reasoning at the beginning was quite reliable. Why did he become more and more bold as he said it later? ¡°Why, from what he said, it seems like this case was not done by one person? And there seems to be a mole! This is too exaggerated! And what he said can be said to be heart-breaking! He said there was a mole, although he didn¡¯t say it explicitly.Who is it, but doesn't this mean that the traitor will be exposed to everyone? ¡°As far as Pan Yuanhai¡¯s family situation and the circle of friends he associates with are concerned, there are only a few people who can go to the basement of his house downstairs. Needless to say, the most suspect among them is his precious son, Pan Xiucheng! (To be continued, please search Piaotian Literature, the novel will be better and updated faster!
