At this time, Xiao Wei, who had been beside him and had not spoken, suddenly interjected: "Uncle, apart from the General Affairs Department and you, who else has the key to the school?"

Lao Li Tou replied: "There should be no more." That is, these two places are available, and the others are not allowed to have them. ”

Xiao Wei then asked: "I may not have made it clear, what I mean is that no matter whether it is in accordance with the regulations or not, as long as there are any." “

"I don't know. Lao Li Tou said.

"Oh, I see. Xiao Wei motioned for Wang Tao to continue.

"Uncle, how is this teacher Shi Mingkai usually doing in the school?"

"Usually the performance is not bad, but I like to be a little smart, plus there is no relationship with the above, so the relationship with the teachers and leaders who are injured is average, not very good. ”

"This Shi Mingkai usually has bad habits, such as liking to fight, or having violent tendencies, etc. ”

"Didn't find it. In all fairness, although this Shi Mingkai teaches sports, in addition to being lively, he is still very stable, and he didn't find any bad behavior. ”

"In that case, let's not talk about any evidence, but based on feelings, do you think Shi Mingkai would kill Jiang Lina?" Wang Tao asked step by step.

Lao Li Tou looked at Wang Tao, hesitated for a while, and said: "It's not good to say, it's hard to say, as the saying goes: Knowing people and knowing faces doesn't know their hearts, people's hearts are separated from their stomachs, who knows what people think in their hearts." ”

"Uncle, let me ask one last question. I read the book that it says that there are two kinds of murder. One is premeditated homicide, which is called murder. There is also a temporary intention, which is called passion killing. If this Shi Mingkai is the murderer, which one do you think it will be?"

"You doll, why do you always act like a prisoner, and you really think of yourself as a detective. Old Li Tou smiled.

"That's not what it means, aren't we idle here and have nothing to do with random analysis. Wang Tao himself realized that it was too straightforward, and smiled embarrassedly.

"Of course I know this, or I wouldn't be talking nonsense with you here. If you want me to say, he must belong to the latter kind, improvised, if you want to say that he planned to kill someone in advance, I don't think Shi Mingkai will not, he doesn't have the guts, and he won't have so much hatred. ”

"That's right. But, sir, I've heard that there may be something new in this case. Wang Tao began to play a strategy.

Lao Li Tou was a little surprised: "New situation? Shi Mingkai is still locked up inside. ”

Wang Tao continued: "It's right to be locked up inside. However, I heard that Shi Mingkai resolutely refused to admit that he killed the person, and kept shouting that he was wronged. ”

Wang Tao saw Lao Li Tou looking at him suspiciously, and quickly explained: "One of my neighbors is in the serious crime team of the Public Security Bureau, and I heard someone say it inadvertently when I visited the door. ”

"Then if that's the case, it's really not Shi Mingkai who killed this Baoqi person?" said Lao Li Tou.

"Don't say it, it's really possible, and it's very likely. Two days ago, I heard that the Public Security Bureau didn't come to the school to investigate for a few days? ”

"Yes, I know that. The school leader said that he needed to supplement the evidence and go through the procedures, but did not say anything else," said Lao Li Tou.

"Can this public security bureau say it clearly? This is to be kept secret, how can it be said casually. Wang Tao looked at what he said and was about to end: "Uncle, I see that there are other murderers in this case, if you think of any situation, remember to tell me, maybe I can make a meritorious service, if I want to be a policeman in the future, I must not be given priority." Just do me a favor. You can keep the cigarettes and smoke them, and I'll bring you a good box of cigarettes next time. ”

After Wang Tao finished speaking, he got up and prepared to leave.

Xiao Wei also stood up, but his eyes never left Lao Litou's body.

Lao Li nodded and didn't speak, as if he was sitting there thoughtfully.

Out of the door, Xiao Wei just wanted to speak, Wang Tao signaled not to talk yet, and when he was far away, Wang Tao said: "After talking, how do you feel?"

Xiao Wei pondered for a moment and said, "I kept observing Lao Li Tou just now, and according to my judgment, he was lying. ”

"Oh?" Wang Tao was a little surprised, and looked at Xiao Wei next to him with interest: "That brother, tell me, how did you see that Lao Li Tou was lying?"

Xiao Wei looked around: "Brother Wang, then let's find a place, sit down, and I'll tell you slowly, do you think my analysis makes sense?"

"Okay, where do you go, the school is still familiar to you. ”

"There shouldn't be anyone in the boys' dormitory now, so let's go there. ”

After discussing it, the two went straight to the boys' dormitory.

It's still evening self-study time at school, and the dormitory is empty.

Xiao Wei skillfully touched the key from the door to open the door, and then saw that there was no one in the house, and then closed the door again.

The two sat down, Xiao Wei touched the cigarette on his body and handed it to Wang Tao.

Lighting a cigarette, Xiao Wei began to speak.

"Actually, when you were talking to Lao Li Tou, I had been observing Lao Li Tou's every move. In fact, both Conan Doyle and Hitchcock paid attention to describing a person's micro-expressions and micro-movements. Therefore, the detectives they write about often judge the authenticity of a person's words from his micro-expressions and micro-movements. There should be a course in this area in your police academy, which seems to be called "Criminal Psychology", which is only a part of criminal psychology. ”

"You're right, this is a very important skill for a police officer, I didn't expect you to know this?" Wang Tao was surprised, he had to reacquaint himself with the high school student in front of him, and looked at him differently.

Wang Tao was full of admiration for the captain Yi Qing at this time, this internal equipment was simply amazing.

Xiao Wei continued: "At the beginning just now, Lao Li Tou was still in a very relaxed state. However, when you ask for the key to the laboratory building, he becomes alert and obviously on guard. ”

Seeing Wang Tao's somewhat puzzled expression, Xiao Wei further explained: "At that time, as soon as you mentioned the key, Lao Li was stunned for a moment, and then made a movement that his eyes began to stare at your eyes all the time, and the word key was repeated twice. ”

This shows that the word key is very sensitive to him, and there is a subconscious psychology of avoiding and exploring the other party's purpose. Also, if he stares into your eyes, it is a sign of lying, and he wants to judge through your eyes whether he believes his words or not. And when he answered the question about the key, his voice was stiff and repeated, indicating that he was thinking about how to answer, which is also a typical lie. ”

The last point, and the most difficult point to hide, was that he rubbed his nose at that time, which was subconscious, and maybe he wouldn't realize it himself. Because when a person lies, the cavernous body in the nose is prone to heat and itch, so based on the above points, I can basically conclude that he is lying. Or at least, there is something to hide. ”
