Access to surveillance is a means, but many times, it is impossible to take care of it thoroughly in this kind of banquet hall, not to mention that the place where Dong Hansheng died was in the small box next to it, and there was no camera here. The only thing that would work was to narrow it down, because, by speculating on the time of death, it was almost certain who had passed by the small box.

After comparing the surveillance and checking the confessions of everyone at the scene, the police almost focused on eight people. Zhou Quan's meaning is also very clear, if the murderer can be caught directly at the scene, it will naturally save a lot of things, so he is also more inclined to handle the case on the spot.

Because I am not a stranger to him, and with his instinctive trust in me, Zhou Quan hopes that I can make some good suggestions.

"First of all, how did he manage to enter the room and still come out without anyone noticing that he had committed a crime?" Zhou Quan raised his questions.

Just now, I have already thought about this problem, and I have almost figured out the whole process of committing the crime.

First, if the murderer is Chen Yuhang, there is naturally no doubt about it, everything is very easy to explain. Chen Yuhang killed people in the room, and it made sense that he didn't come out himself.

But what is Chen Yuhang's motive? I don't know, this needs to be tracked by the police, but on the surface, it seems impossible for Chen Yuhang to kill Dong Hansheng so simply. After all, as a banker with an absolute future, he would kill people with such shoddy and direct means? The answer, at least ninety percent, is no.

At the same time, Chen Yuhang had already done a alcohol test on the spot, and he was basically drunk and unconscious, in this case, could he still accurately stab Dong Hansheng in the fatal position? This is also very suspicious.

Therefore, we have to focus on the second possibility, the murderer is not Chen Yuhang, there is definitely someone else. And this person is definitely not a so-called wall-piercing technique or stealth method, he uses some skills to carry out the killing process.

"After the incident, we have learned from the surveillance that no one has ever gone out except for the waiter who has entered and exited the service, so the murderer must have been someone who was present at the scene, or a waiter who had come in to serve. I noticed that after the waiter found out about the scene in the box, many people immediately gathered and even rushed into the room to see the situation. The scene was very chaotic at the time, and we assume that after the murderer committed the murder, he did not leave the room at all, but hid behind the door, and then took advantage of the chaos to mix in the crowd to confuse the public, which is very likely! ”

Zhou Quan agreed: "I also thought of this!" Because it was impossible for the murderer to leave, and the murder weapon was also left in the room, he must still be in the middle of the crowd. The reason why he was able to go unnoticed may have something to do with his identity. ”

"Haha, Officer Zhou really thought of the key, yes, if you remove the waiter factor, everyone here is attending the class reunion, generally speaking, if it is a focus person, even if you leave for a while, if the reason is unknown, it will attract attention. This person was able to kill people quietly, and he could still be ignored by everyone, basically concluding that his presence at the scene was actually insufficient. So, if we want to catch the murderer now, we need to go through two steps at the same time. First, it is actually easy to thoroughly investigate the waiter who has just come in and out, after all, the foreman manager can help, and if someone has a suspicious motive, it can be quickly discovered. Second, it is necessary to continue to exclude the eight people who have just been identified at the scene, and then conduct a targeted investigation after narrowing down the list. ”

In the list of eight suspicious people just determined, it can be basically determined that there are four people who do not meet the situation I just mentioned, because these four people are also active at the scene, and it is easy to confirm that they have no time to commit crimes, including Chen Yifei, and the "pretending to be a man with an annual salary of one million" who has just been ridiculed by Shen Li. Among the remaining four, Zhang Lei does lack a sense of existence, but I always feel that he is not a killer, as for the reason, I have already explained before, when he is not greatly stimulated, it is difficult to cause the urge to kill immediately for the second time at the scene. Moreover, when he found out that Dong Hansheng had died, the expression on his face was indeed not a disguise!

That, the list of the last three!

Tan Ailing, female, looks ordinary, and doesn't talk much, if it weren't for Zhou Quan providing me with confession information, I don't remember that there was this sister at the scene.

Gong Cheng, a small man with glasses, except for greeting me when he was taking pictures, after that, I really didn't seem to see him say anything.

Drama friend Sen, can only be described as a very passerby.

These three people also have a common characteristic, that is, their clothing is also extremely ordinary, there is no conspicuous place, which is also directly caused, if they "disappear for a short time", basically no one will pay attention, and even in people's minds, because there is no significant label on them, so, it is difficult to find in the crowd!

"If it is not a professional killer, especially the first time to kill, then, it is impossible for him to be extremely calm, at this moment, the murderer's heart must be extremely frightened, so his body movements should first be panicked, then his hands and feet are cold, and his forehead is in a cold sweat. Because the police are looking for clues everywhere, at this moment, the murderer's body should be inclined to flee in the direction of escape, and when the police look at him, his eyes will immediately look away, appearing weak. ”

When I said these words, Zhou Quan was already looking at the three of them. However, because of the introverted personalities of these three people, they were very nervous at this time and did not dare to look at each other. From this alone, it is impossible to judge it directly.

So, we need to do an experiment.

"Tan Ailing, Gong Cheng, and Drama Yousen, the three of you come out." When Zhou Quan reported the names of the three people, there was a hint of noise in the depressing atmosphere of the scene.

Everyone began to talk to each other, and they didn't know what was going on. Lin Xinting and Shen Li both cast puzzled glances at me, but I obviously won't tell them the answer now.

Zhou Quan brought four people, including me, to the criminal's box, and at this time, the forensic personnel were still collecting evidence at the scene, and the bloodstains had not yet been cleaned, and the corpses were placed there, and everything seemed extremely shocking and real. I could see fear in the eyes of all three of them, and at the same time, they all made fearful evasive gestures.

"I won't beat around the bush, I'll tell you the truth." Zhou Quan said, "We have collected confessions, and compared the surveillance data, and through analysis, we have basically concluded that the murderer of Dong Hansheng is between the three of you." ”

"No, it's not me, it's not." Tan Ailing was so frightened that her body softened, and she fell directly to the ground and said, "You can't wronged me." ”

Gong Cheng also hurriedly shouted: "How can you wronged me. ”

"It's not me, don't frame me." Drama Yousen waved his hands and made a nervous costume.

Zhou Quan said: "Don't worry, our police will not wronged the innocent, but we will never let go of the bad guys." Now, I'm going to give that killer a chance, and if he comes forward, he'll turn himself in. ”

Time stood still at that moment, Zhou Quan and I stared at the three of them, and the three of them all lowered their heads and did not dare to look directly, and at the same time, some people made a move to look to the side and check the reactions of the people around them.

Tick-tock, everyone's heart, as if there was a minute hand moving, a full three minutes later, Zhou Quan hummed and said: "Okay, I have already given you a chance, but you are unwilling to stand up, no matter what, next, I can't help you." Eileen Tan. ”

"Ahh What the..... What the... It's not me, it's not me. Tan Ailing kept waving her hands and stepped back nervously, "It's not me." ”

As she spoke, tears of urgency were already flowing out.

Zhou Quan waved his hand and said, "What are you nervous about, I just want to ask you how you think the murderer committed the crime." ”

"How do I know, I don't know, I really don't know." Tan Ailing sobbed, squatted on the ground with her arms folded, and finally whimpered and cried.

"Gong Cheng."

"Ahh It's not me, and I'm not a murderer. Gongcheng anxiously argued.

"Hey, hey, I said what are you nervous about, the girls are scared and crying, so it's easy to explain, you big man, if it's not a murderer, why are you nervous. I also want to ask you how you think the murderer committed the crime. ”

"I don't know, I don't know."

"What do you think?"

"I don't know." Yousen's voice trembled, "I'm not a murderer, I don't know how to kill someone." ”

"Well, if you don't say it, I'll do it."

Zhou Quan thoroughly recounted what I had just analyzed with him, and when he said these words, I carefully observed the three people at the scene, and from the current situation, there were indeed people who had already shown their feet.

The reason why I asked Zhou Quan to do this experiment is because I want to compare the tension difference between the three people, because the tension after killing is different from the tension of being wronged because of the fear of getting into trouble, but this difference is not obvious because of the personalities of the three people, so I need to deliberately create a more nervous and targeted test to make them show excessive tension and fear.

Just now, I basically saw the clues. My gaze re-examined the three of them, someone, no longer able to disguise it.

"Officer Zhou, I think it's time for the game to end."

When I said this, Zhou Quan's face showed joy: "Oh, who is it?" ”

"Before I say the answer, I would love to say something to the murderer, why bother? You are not a competent killer at all, although you have been planning for this for a long time, but your psychological quality has not passed the test at all. When Officer Zhou needed the killer to take the initiative to turn himself in, the real murderer knew that no one would stand up except him, so it was impossible for him to pay attention to the reactions of the people next to him. At the same time, when Officer Zhou recounted the entire murder, the real murderer, because he had already known all this, would not pay attention to Officer Zhou's description at all, and his attention should continue to maintain tension while observing the surrounding environment in order to find an escape state for himself. One of the three of you has already made a major flaw in his behavior in the above description, and he should know very well who I am talking about. The murderer is you。。。。。 ”
