Suspect Y is clearly a mind-type criminal who focuses on hacking techniques and mental work. For a person who stays in front of the computer all the year round and studies computer technology, it is a normal thing for the limbs to degenerate and the body to be weak. The place where Hu Jie died was on the 3rd floor, and he needed to climb up through the water pipe and the anti-theft net, and then use the key to open the small door on the anti-theft net, and then climb in and kill the deceased Hu Jie with a knife. There is a period in which you have to rely on arm pull-ups to continue climbing, but for many ordinary people, it is very difficult to complete pull-ups, let alone a mental worker with degenerated limbs, which will be very difficult.

"I can't say the same thing, it's not uncommon for people to do technology and exercise at home. But I don't think he can do it himself, so in my opinion, there must be something unknown in this case, maybe it's a hired killing, or a remote control killing. ”

Zhou Yunkai said: "I squatted downstairs for nearly 1 hour, covering 2:30 to 3:30. I didn't see anyone crawling through the window to Hu Jie's house, and I thought I should have been tricked by that person. The time of the incident was either before 2:30 or after I left, and it was not exactly 3 o'clock as he said. ”

"Personally, I tend to prefer the latter, we are a famous city in the country that never sleeps, and there are countless night food stalls around 1-2 o'clock in the evening, and it is easy to be noticed when you do it during that time. So I suspect it was done around 4 o'clock in the dead of night. ”

"That's how it should be."

"Actually, we should go to the school now, and if I'm not mistaken, the door to our classroom must have been pried open."

"Isn't the school building locked during the summer vacation?"

"There is no lock at the staircase of our school's school building, only the entrance is locked with a sliding iron door. There is a platform on the 2nd floor where you can climb into the classroom. For a man who can climb to the 3rd floor with his bare hands, this is obviously not difficult for him. ”

"That's just as well."

Lin Ming's IQ is not as high as Zhang Shao'an's, and he doesn't read as many criminal files as Zhou Yunkai. The train of thought obviously couldn't keep up with the two of them, and they couldn't insert a word. With a word from you and a word from me, the matter has been outlined and analyzed much more clearly.

Finally, Zhang Shaoan concluded.

Suspect Y, Identity: Hacker. Age: Unknown. Gender: Unknown.

Zhang Shaoan speculated that this person was a degraded otaku, because judging from his perennial stay in front of the computer, he should have few opportunities to exercise.

So it wasn't the suspect Y himself who did it.

Zhou Yunkai thinks that this person is an extremely smart person, and generally this kind of person will never kill people in person. It's like sitting in the president's office, and the boss who is high up in the front desk will never stand at the front desk to greet him. Smart people are more proud, and they don't bother to do such untechnical things.

So it wasn't the suspect Y himself who did it.

Although the two had different opinions, they had the same result.

Zhang Shaoan reasoned based on the actual situation, and Zhou Yunkai made conclusions based on criminal psychology.

It is believed that Hu Jie was not killed by Suspect Y himself, and Suspect Y is not necessarily a native of Cloud City. Hu Jie's death may have been a hired murder or a remotely directed murder.

Among the clues given so far, this speculation is at least 80% or more.

About how to blame Zhou Yunkai.

They also believe that it should be at school that they found Zhou Yunkai's desk, used tools to copy fingerprints, made fingerprint films, and planted blame.

At present, the two believe that they should go to the school to confirm it to prove their conjecture.

If the source of the fingerprint is not the school, then there are some things that are extremely scary to think about.

After listening to their analysis, Lin Ming fell into deep thought.

In front of the two of them. He is like Li Yuanfang who is followed by two Di Renjie, just one sentence away, there must be something strange about this matter.

But as the saying goes, a wise man must make a mistake in a thousand thoughts, and a fool must gain a thousand thoughts.

Lin Ming suddenly remembered that when he was chatting with intern criminal policeman Zhou Sheng before, there was a conversation that was very wrong.

Here's the conversation.

"The most intuitive evidence is that the murderer cleaned up the scene, the footprints on the windows and the ground were wiped clean, the floor was as bright as a white wall, and even under the bed. The team guessed that the culprit must be a person with a regular lifestyle, cleanliness or obsessive-compulsive disorder. ”

This sentence is a visual expression of the evidence that the murderer came in from the window. Because if the murderer entered the scene from the doorway. Then he will definitely not clean the marks on the windows. It's like there is a surveillance at the east gate, but there is no surveillance at the west gate, and the thief can sneak in from the west gate, but he still runs to the east gate to destroy the surveillance.

Bring sand to the beach!

This sentence can indeed be used as strong evidence that the murderer came in from the window.

However, Lin Ming suddenly realized that there was something wrong with a sentence in it. Because it also belongs to the category of redundant acts, but the murderer did it anyway.

Even under the bed, it was cleaned again.

At a murder scene that will be discovered at any time, the murderer does not hurry to clean the house. Even where there is no trace of himself at all, he has to clean it up, is this murderer still a socialist youth pacesetter, a modern version of Lei Feng?

This kind of thing obviously doesn't exist.

Then there is only one answer, under the bed, there must have been traces of the murderer. He'd clean under the bed because he'd been underneath.

Imagine that the murderer sneaked into the room by unknown means and hid under the bed long before Hu Jie finished eating supper. Waiting for Hu Jie's horses to help Hu Jie come back and open the door with the key, the murderer was in the dark, looking at the people outside with a pair of cold eyes, and after the horses left, he got up from under the bed and stabbed Hu Jie. After killing Hu Jie, he calmly cleaned up the scene, and quietly left through the window under the cover of darkness. In this way, even if at 2:30 and 3:30, Zhou Yunkai stood under Hu Jie's window, waiting for the murderer to come to the door, he would only get a ridicule and sneer from the murderer who had already finished the murder.

When Lin Ming told them this idea, both of them were silent for a while.

After a while, Zhang Shaoan said: "We haven't been to the scene, and the information is not sufficient. Or underestimate this murderer, I guess, he deliberately said 3 o'clock to deceive us. Then kill Hu Jie in advance, so that even if he calls the police to ambush outside, he can calmly retreat. ”

"There is another point, suspect Y told us exactly 3 o'clock a few days in advance, how did he know that Hu Jie would be back before 3 o'clock? How did you determine the specific time of Hu Jie, who had such an irregular schedule? ”

Zhou Yunkai said: "Actually, I have considered this aspect before, but I have never figured out how he wants to control Hu Jie's actions and accurately let him be at home at 3 o'clock." It wasn't until Lin Ming said that even the bottom of the bed had been cleaned up, and I understood. As early as the day before, the murderer was hiding under the bed. Because no matter what, Hu Jie always has to go home and sleep. So the information he gave me about the time of death was simply used to trick me, or mislead me. The real situation is that when Hu Jie will come back, when will it be the time of death, and it will not be 3 o'clock at all. Give me 3 o'clock as time, if Hu Jie doesn't come back until after 3 o'clock, and if I break in with the police, it will definitely alarm Hu Jie and the murderer, and the murderer will not do it. But at the same time, it will also make the drug trafficking case fail, and I will lose half of the competition before we even start. If Hu Jie had come back before 3 o'clock, because I had been given a specific time, I would definitely not have brought the police in advance, so the murderer would have had time to kill, clean up the scene, and then find a way to leave calmly. ”

"This murderer is really smart and takes everything into account. Regardless of whether Hu Jie was before or after 3 o'clock, the murderer was able to escape calmly. Because even if Hu Jie goes home after 3 o'clock, we are afraid that he will accidentally break in, and we will never temporarily search under the bed. When he went home before 3 o'clock, he could be sure if there was a police ambush below, and then according to the actual situation, he would go out through the door or climb out of the window. In this way, no one will ever find out or notice that the murderer has entered the house in any case. Even the deceased, while sleeping, would not have thought that someone would come in. As long as the doors and windows are closed, he will sleep comfortably. ”

Zhang Shaoan said: "In fact, it is impossible for the murderer to know whether Hu Jie was drunk or not. If you climb through the window, it is easy to make a noise and wake up the person who is asleep. So hide under the bed and you're sure nothing goes wrong. ”

Lin Ming and Zhou Yunkai nodded.

This murderer was very confident, and first told Zhou Yunkai the death information very bluntly, not afraid that he would bring the police to arrest people in advance. Then hide under the bed, clean up the scene after the bold killing, and leave calmly.

This is because he has a detailed and elaborate plan to kill.

Although this kind of plan does not guarantee that there will be no problem at all, even if he catches him before he kills, he can say that he is a thief. And after the killing, Hu Jie's horses left with their front feet, and he could follow with his back feet, as long as there was no police ambush at the door, he could walk through the gate.

And the purpose of his walking through the window is probably because he has determined that there is no police ambush in this vicinity. After all, there are voice-activated lights in the corridor, and if you leave the corridor in the middle of the night, if you bump into someone, you may meet the first witness and see his face. So after making sure that there were no police, he definitely escaped through the window.

Because the window where Hu Jie lives is not the street leading to the exit of the building, but a very remote path behind. Three watches in the middle of the night, dark and black. Even Zhou Yunkai could only use the moonlight to stare at the window from afar, not to mention that he only needed to make sure that there was no one in the alley, and he could easily leave through the window.

"It's not difficult to figure out the murder method, but it's hard to find the murderer." Zhou Yunkai said: "I can be sure that suspect Y will never do it himself, so he must have instructed others to do it." But who is this person, Hu Jie's enemy, or a professional killer? ”

Zhang Shaoan groaned: "I think let's go to the school first, and then go home, Uncle Zhou, you also need to explain it to him." Make excuses for yourself or take the initiative to explain, you make your own decisions. Also, I suggest you check out that forum, Y will definitely leave you a message. ”

"Well, that's what I thought too. Let's divide the soldiers into two ways, you and Lin Ming go to school, and I'll go home now. ”

Lin Ming said: "It's better to divide the soldiers into three ways, I'm going to my uncle now, and follow him to learn about the progress of the police in solving the case." You follow the clues you have thought of to investigate, we have things in our hands that the police do not have, they have the convenience of ready-made investigations, and the two sides can exchange information to find the murderer faster. ”

Zhou Yunkai nodded: "This is the best." ”

The three of them acted separately, and Zhang Shaoan went to the school to determine the source of the fingerprints. Zhou Yunkai went home to read the online forum and explained the situation to his parents by the way. Lin Ming wants to annoy his little uncle, and the criminal police will obviously not let people go with him when he goes to the scene of the crime, but Lin Ming has to play his hard work and rely on him.
