An orchestrated suicide, it's the perfect murder.

And the biggest key to this perfection lies in the message in the WeChat group, before Zhang Mengdi fell to her death, she posted something like that, she admitted that she was an instigator, and she said goodbye to everyone.

So, if according to Wu Gan's reasoning, if this is a murder, Zhang Mengdi should be asleep, she just woke up before she fell downstairs, so how can these messages sent by Zhang Mengdi's WeChat account be explained?

Wu Qian faced Li Xue, and he said very formally: "If I want to plan such a perfect murder, my absence proves that this is necessary, and it must be perfect."

WeChat, really a handy tool, I will make good use of this murder.

That is, Zhang Mengdi's so-called suicide last words and confession were not sent by her, but by me.

I sent it through the WeChat web version!"

When he said this, Li Xue asked stiffly, "Hehe...... How is this possible? Are you going to steal Zhang Mengdi's WeChat account?"

Wu Qian continued: "If it were me, I wouldn't have this technology, and I wouldn't steal any numbers." However, I have a very simple way to log in to her WeChat on the web version.

There are several features of the WeChat web version that can be exploited.

First of all, it is very simple to log in to the web version, that is, to scan the QR code. ”

"Hehe......" Li Xue laughed contemptuously, "But, how to sweep it? You know, you have to use Zhang Mengdi's mobile phone to scan it when you log in to the web version of WeChat." ”

Wu Qian nodded, "It's true, but it's actually very simple."

If it were me, I would first open my own laptop, open the browser, log in to the WeChat web version, at this time, the QR code appeared, and then, I used Zhang Mengdi's mobile phone to click on her WeChat, scan this QR code to log in, this is OK. ”

"......" Li Xue's face became gloomy again.

"Do you want to say, I can't use Zhang Mengdi's mobile phone? Li Xue, the current mobile phones are all fingerprint locks, Zhang Mengdi is next to me, her ten fingers are not my word, unlocking her mobile phone is as easy as a breeze. Now the fingerprint lock is very convenient, many people do not set the WeChat password at all, as long as the phone is opened, then, Zhang Mengdi's WeChat will be used at will, and you are still her bedmate, you should understand her habits.

That's why I can set the alarm time on Zhang Mengdi's phone, and her fingers are all at my disposal, and besides, it's just to unlock it once. ”

At this point, Li Xue stopped talking.

Wu Qian continued: "It's that simple, but there is one thing that needs to be done, that is, the web version of the account has not been offline, and in terms of laptops, it must always be turned on, which is a strange place." ”

Wu Gan's words seemed to be very relaxed, but in fact, this had already shattered Li Xue's alibi.

If Lin Bing could hear it now, then she would definitely help Wu Qian prove that it was true, Li Xue today was always on her laptop.

However, this is not a problem and cannot be used as evidence at all.

"You're so sure I sent it?" Li Xue asked with a smile.

"There is no one else but you, and, I estimate, at the orientation party, when your show changed scenes, you sent out the typed confession and suicide last words, that is, I am likely to find witnesses, and some classmates may see you operating a laptop at that time. ”

It's all unraveled!

As long as Li Xue sends those WeChat messages before the alarm time of Zhang Mengdi's mobile phone set by herself, then this creates the illusion that Zhang Mengdi committed suicide, and she, the murderer, is participating in the welcome performance in the gymnasium far away from the No. 16 dormitory at this time.

And!

"Another feature of the web version of WeChat is that as long as you log out, the previous record will be erased. ”

This is a perfect alibi, and now, it has been perfectly debunked by Wu Gan!

It stands to reason that Li Xue should plead guilty at this time, but she asked with a smile: "Do you have evidence?"

Wu Qian spread his hands helplessly and said, "All of the above are explained by me from the perspective of murder. To put it simply, I insisted on treating such a case as murder. No way, I'm sure that any policeman who comes and sees the scene, even if he checks everything, he will think that this is suicide. Moreover, what I have said above is basically not taken as evidence. ”

Wu Qian seemed to be a little tired from squatting and talking, so he simply sat down, and continued: "Ether, Qin Yan went to the affiliated hospital and didn't find any clues, this thing is really not good, but it's not impossible, the volatility of ether is too strong, the person who helps you get ether, the best way to say it is to never admit it, just treat it as an operation error."

Moreover, this thing itself is highly volatile, and it cannot be tested at all on Zhang Mengdi and other people's bodies, so even if you keep it, there is no problem, you are studying the Fa, and you understand that this cannot be used as evidence at all.

Sleeping pills, Zhang Mengdi is also taking, which cannot be used as evidence, and she woke up naturally at all, and the forensic doctor can't detect any problems.

In addition, ether as an anesthetic combined with sedative drugs such as sleeping pills can cause people to fall into a deep sleep, which is itself a very specialized medical knowledge and is generally used to relieve pain after surgery...... I don't know how you know, you don't study medicine, I can only speculate that you have something to do with the hospital.

The syringe was not found, and even if it did, it would not indicate any problem, and there would not be any fingerprints on it.

An old phone is similar to a syringe, and you don't necessarily use an old phone, so there may be another way to calibrate it.

The roof key is a good thing, but you should also have your own statement, now that school has just started, the peak period for college students to dry quilts, secretly with a key, for convenience, is not a big crime.

You also happen to wear a labor protection glove in order to disassemble the wires, this thing is very cheap, and it will not arouse suspicion if you use it casually, and it will not leave any clues.

In addition, these things can't be found at all, I asked, our school will clear all the garbage bins before 9 o'clock in the morning, I guess, after you finish those jobs on the rooftop, just throw the garbage cans, and there is no evidence.

The most powerful suicide words in the WeChat group and confessions,That's even more sorry,As long as you log out of the web version of WeChat,Then,There is no record,And,Your laptop and Zhang Mengdi's mobile phone are connected to the campus WIFI,I roughly asked the students who understand this,Their answers are,It's really too difficult to find out,This is instant messaging software,Even if you can be sure that Zhang Mengdi's last words are sent by the web version of WeChat,But whose computer is used?

As for the fact that you have been driving your laptop strangely, that doesn't serve as evidence of a crime.

Li Xue, you did a perfect murder, Zhang Mengdi's death from a building can be closed by suicide. ”

Li Xue smiled after hearing this, "Wu Gan, you said me too much, I will be proud and complacent, is it really as perfect as you say?"

"I bet that almost all police officers look at such a case, Zhang Mengdi's suicide, and he will decide that it is a suicide. No way, I can't find anything wrong, and almost everyone has given you an alibi. ”

"I still don't believe it's so perfect. ”

Wu Qian thought for a moment, "Do you really want to hear it?"

"Yes. ”

"There is indeed a little bit of a flaw. ”
