"Just from such a door and such a storage room, you can conclude that he killed this case? Wouldn't that be too hasty, at least you should come up with some evidence, someone can get through the storage room and enter this villa, right? As far as I know, when the local police station arrived at the scene, all the doors of this villa were locked, the courtyard door, the door of the villa, and even the door of the basement you just mentioned were locked. ”

This time it was Jing Nan who asked the question, he usually didn't talk to Li Xiangdong much, but almost everyone in the bureau knew that this first brother of the city bureau liked Li Xiangdong, a newborn calf, and it could even be said that he almost didn't treat him as a godson.

Several times, this kid got into trouble, and in the end, even the first brother of the provincial department wanted to deal with him, but it turned out that the first brother of the city bureau saved him under pressure.

Now the first brother of the city bureau seems to be interrogating 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 for the purpose of an old criminal investigator, he is guiding and protecting him.

The questions of the well-meaning are always kinder and easier to answer than the questions of the people who have bad intentions towards you.

It is true that this is a key, the most headache for everyone before, is this case, although there are many doubts, but the key is that if you want to list this case as homicide, then you have to face the first problem, that is, the confined environment of the crime scene.

This completely belongs to the kind of locked room murder cases that Conan or Kaneda often encounter.

If there is an outsider committing the crime, then how is the confined environment of this scene created?

Even if the basement door doesn't have an alarm system connecting the entire apartment, the door is locked when the police arrive, and more importantly, it's more important. This door is not your average 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 are absolutely real.

The frame is not the kind of ordinary plastic steel, but the use of aluminum-clad wooden structure, such a frame can ensure that it is used for a long time without deformation, if it is a frame of plastic steel, with a few years, the frame will definitely be deformed.

And this kind of bezel is guaranteed not to deform, so it is not so easy to pick the door lock from the outside. And even if you use a credit card or something to pick the lock, if you want to pick the door lock, it will always leave marks on the door frame and on the lock.

But now the news from the trace examination department is that there is no obvious sign of prying on the door lock.

In this way, Jing Nan's questioning is very crucial.

But you said that the basement storage room is suspicious, this room is clean, and there are traces of wiping on the doorknobs, and even the floor leading to the upper floors has been wiped off.

But there is one issue that is critical. Even if there are indeed traces of wiping on these paths, how did the suspect enter the scene?

The door was well locked when the police came, and there was no sign of it being picked open. So how did the suspect get to the scene?

And after committing the case, how did you leave? The most important thing is how did he lock the door when he left?

These puzzles all need you Li Xiangdong to solve, anyway, the doubts are raised by you. And the person you said was killed by him, so of course, the key suspicion of this closed room murder case should also be answered by you.

Jing Nan's question is to the point. Li Xiangdong said a few doubts before, and everyone pondered it, right, it seems to be like this.

Listening to Li Xiangdong say this, this Pan Yuanhai is indeed very likely to have died by him.

But now, Director Jing, when he said this, everyone suddenly remembered that the key to this case, if this is a special homicide case, this is a closed room murder case!

Even if the doors and windows in the basement are not connected to the electronic alarm system, it seems that it is not so easy for an outsider to enter and exit the scene freely, right?

How the hell is this secret room made? How did the suspect get in, you really have to give a reasonable explanation!

At this time, in the entire conference room, almost everyone's eyes were focused on Li Xiangdong, and everyone wanted to see what kind of surprise this amazing boy could bring to everyone this time.

Originally, some people wanted to see him make a fool of himself, after all, this secret room problem, it is not so easy to solve, if this guy is not prepared, it must be a mess at this time.

But Li Xiangdong once again disappointed those guys with dark hearts, and at this time, this guy's smile was actually full of confidence.

"Hehe, okay, I'll show you what to do, enter and exit this scene, and create a closed room killing environment."

After speaking, he waved his hand, and at this time, a few teammates from the criminal police team quickly brought in a glass sliding door, which was specially ordered by Li Xiangdong before entering the conference room, and several teammates in the team helped to find it.

Just some time ago, the first criminal investigation team detected a case of building materials theft, and a lot of thieves came out of the thieves' den, including various steel bars, and plastic steel doors and windows, among which there are several more high-end plastic steel doors and windows, which are similar to Pan Yuanhai's home, although not as good as Pan Yuanhai's family, but not a lot worse.

At the same time, Li Xiangdong escaped from his pocket with a thin roll of fishing line, which happened to be bought by him on the way back.

He asked two teammates to hold the door, then tied the buckle inside the door with a fishing line, then closed the door and locked it, and then reached out and pulled the half of the fishing line that leaked out of the door, almost without any effort, the locked buckle was pulled open from the outside, and then gently pulled the fishing line, and the sliding door was opened.

Then close the sliding door again, and then pull the buckle downward, and it is easy to lock the buckle from the outside of the door.

And as long as the fishing line tied to the buckle is used in the live buckle method, then as long as the force is a little bigger, you can lock the buckle at the same time, but also be able to pull the buckle open, and then gently pull the fishing line out with a light outside, and then a closed on-site environment is completed!

Li Xiangdong demonstrated this, almost everyone at the scene was in a state of dumbfounded, a closed scene that was originally thought to be more difficult than the sky, can be cracked so easily?

This guy barely made any effort, and with just a fishing line, he could easily open and close the door?

The security measures of the Qingshan Yunhai community are indeed very strict, but it is not an impossible task to enter the community, and the courtyard of Pan Yuanhai's house, although the gate is locked, if you climb over the wall to enter, it is not very difficult, and the courtyard wall of his house is not like the courtyard wall of the community, which is equipped with any surveillance cameras.

And the last line of defense of their family, that is, the problem of entering and exiting the villa, was also solved by Li Xiangdong so easily, so that the possibility of him killing in this case suddenly increased sharply!

If before, there were still many people who were 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 were originally the most suspicious group, but now there are many people who have begun to make this case official, and it is regarded as a criminal case of homicide.

"So now I have one more question!"

Jing Nan asked again at this time, the scene was already a bit more and more strict, and at this moment it became even more silent, as if even a needle fell on the ground, everyone could hear it, and there was silence.

Li Xiangdong nodded, indicating that he was ready to take the call.

"You just cracked this secret room environment, and the crack is very beautiful, but the key to the problem lies in the first step of entering, let's take a look, first you have to make a live buckle of your fishing line and tie it to the buckle of the door, but when the suspect came, the door was locked, how could he tie the fishing line to this bayonet when the door was locked?"

Jing Nan asked, and the people at the scene only realized at this time, it was really such a problem, it was quite novel to watch the kid open the door with a fishing line before, and completely forgot about it, what if the door was locked when the suspect came?

At this time, Li Xiangdong suddenly smiled cheaply.

"Who said that when this suspect came, this door was locked? And who says that this case is a case done by one person? ”

"What!"

As soon as Li Xiangdong said this, it was almost like dropping a bombshell at the scene, and even Jing Nan's face suddenly changed at this time, and there were several leaders who directly took the case.

This kid is really bold, and his reasoning at the beginning was quite reliable, why did he say more and more boldly later?

Why, listening to what he meant, it seems that this case was not done by one person? And there seems to be an inner ghost! That's an exaggeration, isn't it?

And his statement can be said to be heart-wrenching!

He said that there was an inner ghost, although he didn't say who it was, but wouldn't this already point out the inner ghost to the big guy?

In terms of Pan Yuanhai's family situation and the circle of friends he has made friends with, there are only a few people who can go to the basement downstairs of his house, not to mention the most suspicious, is his baby son, Pan Xiucheng! (To be continued......)
