In the main hall and conference room

More than 20 police officers sat around the long table, their fingers entangled, like pins and needles, their eyes glancing at the door of the conference room from time to time, pouting in disgust

"Ga~" Suddenly, the door of the room was opened, and the eyes of the police officers instantly looked there, only to see two men, one woman and three figures walking in one after another, it was Zhou Yihan, Lao Si and An Ran

"Then we started laying out the action plan. As soon as he entered the door, Zhou Yihan said this directly, and the police officers were stunned

That's too vigorous, isn't it?

One of the officers asked, "Isn't it necessary to discuss your speculation about the purpose of the Shadow Fiend, the profile of the murderer, the level of knowledge you know about the details of the case, and the basis for the plan?"

Obviously, what the police officer said was the focus of the case, but Zhou Yihan only paused slightly, then tilted his head and said: "The first shadow demon case happened half a month ago, and so far there have been fourteen consecutive crimes, and the number of victims is as high as more than 30 people, they have no relationship with each other. ”

"So far, you have been to the scene of the crime no less than twenty times, and once did you find that the wallet, ring, necklace, or other valuable items of the deceased had been taken away from the scene? ”

"In the face of such a murderer, his motive must be there, but it is obviously not what we should hold on to now, and the motive of the murderer is unknown, we cannot make a real and effective profile of their specific situation, even if we make it reluctantly, we will only conclude that they are a group of crazy people with extremely serious mental illness and violent tendencies. ”

"But a murderer who doesn't touch any property after killing someone, and doesn't forget to annihilate all the traces he left at the scene, obviously won't be a madman who has an empty mind at the time of committing the crime, and coming to such a conclusion is not helpful to us at all now, why should we waste our poor time discussing these things that are meaningless to solve the case?"

Zhou Yihan made a series of quick and accurate inferences, and in an instant, all the police officers in the room, including An Ran, were dumbfounded, especially the police officer who asked this question, his face was only ashamed, I am afraid that they couldn't figure out why a person who had been locked in a detention center and isolated from the world for seven days could tell all the relevant information about the Shadow Demon case recorded by the police in the past seven days as casually as a few Jiazhen as soon as he was released from prison

I believe that no matter how they speculate, they will never be able to guess that the fourth child has been monitoring all the movements in the police network 24 hours a day since the day Zhou Yihan was detained, and when they come back from the investigation of the scene, as long as they enter the details of the case into the network, the fourth child can easily pocket all the information just like flipping through the villain books on his own bookshelf, until Zhou Yihan was released from prison yesterday and told him all the information

In the conference room, the atmosphere was so embarrassing, and the faces of the police officers were even more embarrassed, of course they didn't know these things, but they didn't know that Zhou Yihan also knew, and he wanted to take this opportunity to give his airborne adviser a dismount, but he didn't think about it, but he was stunned by the shock.

It's like picking your feet while watching TV in your own home, which is nothing, but if someone doesn't notice it and someone else sees it, and that person puts on a disgusted look of sudden realization, it's embarrassing.

An Ran clasped his hands, and when he saw this situation, he suddenly gave him a white look, but on his lips, he warmed up the scene with kindness: "Everyone, we are in a meeting now, please don't interrupt casually, listen carefully to Consultant Zhou, since people can be sent from above, they must have some understanding of our situation, if you have any objections, please express your opinions after others have finished speaking." ”

"Yes. The police officers would not fail to listen to Enron's words, and after sorting out their minds for a while, they opened their notes and prepared to record

Then, An Ran said to Zhou Yihan: "I'm sorry Advisor Zhou, please continue." ”

Xiao Anran.. Interesting. Zhou Yihan pursed his lips and smiled, and continued: "Okay, then let's continue to say, as I said before, the complete randomness of the target chosen by the Shadow Demon is something we can't predict at the moment, so if we want to understand their minds, we have to work hard in other places, my teacher once said that if you want to find out the mind of a murderer, it is nothing more than the four basic elements of motives, places, characters, and techniques. ”

We don't know the motives of the Shadow Demons, the conditions of the chosen targets, or the meaning of the methods of attack, so it is clear that we can only speculate about their thoughts from the rest of the "choose the location of the target". ”

As he spoke, he glanced at the fourth, and the fourth suddenly nodded his head, stepped forward, put the thing that seemed to be a painting in his hand on the table, shook it forward, and the picture scroll suddenly rolled forward, the officers were curious in their hearts, and they poked their heads out to look, Zhou Yihan continued at this time:

"This is a topographic distribution map of the five regions of Rumeng drawn in equal proportions, which records all the street landmarks and B&B buildings in Rumeng City, from the civic square to the independent public toilet, as long as there is something in this urban area, you can find it in this map, before coming, I have already marked all the places where the shadow demon case occurred in advance, Team Leader Xiao, you take a look, count if there is anything missing. ”

Speaking of this map, Zhou Yihan's voice inevitably brought a little pride, and he got up and stepped forward to look at it for a while, and asked in disbelief: "You drew this?"

Her face was full of amazement, and Zhou Yihan spread out his hands and replied, "There was a case that needed to be done before. ”

"You don't look like a painter. ”

An Ran finally muttered so quietly, and began to lean over to face the map, although she had no records in her hand that could be used to compare at the moment, but the place where each Shadow Demon Case occurred seemed to have been imprinted into her mind, coupled with this accurate map of landmarks, it didn't take long for her to check all the locations where the Shadow Demon Case had happened in Rumeng City, and there were a few places that Zhou Yihan did not record were also made up by her

"Okay, now that all the preparations are complete, you have to listen to me carefully. ”

After all this was done, Zhou Yihan walked to the side of the long table with a marker pen that he didn't know where to conjure, and pointed to the map: "There have been fourteen cases of the Shadow Demon Case so far, except for this one in the densely populated central area, all of them happened in the suburbs, lanes or ports after dark, which are sparsely populated and few people will go, this problem itself is not difficult to understand, because after killing people, they have to dismantle the body, which will take a long time." ”

"But what if someone happens to pass by during this time? Then the scene of their murder will be seen by witnesses, and if they can't ensure that the witnesses are killed and killed, they risk being wanted by the police, and in a city where technology is full of cameras, once their appearance is exposed, it is almost impossible to escape." ”

"So they will definitely avoid this risk when they commit murder, once or twice it can be said that they are lucky, but eight times or nine times it must be that they are fully prepared, a disguise that stays in a place for a long time in the middle of the night, even if it is accidentally seen, it will not arouse the suspicion of others. ”

"This camouflage may not be fixed, but it must be useful, but even if you have a camouflage, you must be able to guarantee that you will not be discovered by others during the dismemberment period? No one dares to make this guarantee, so the best way is to work in pairs, one is responsible for doing it, and the other is responsible for letting go of the wind. ”

Hearing this, the officers involuntarily nodded in agreement
