Mystery Hunter - Chapter 15

[Chapter 15]

“Wait.”

A crisp voice came out, and the person who spoke was Jiang He.

Seeing that everyone was looking at him, Jiang He said, “Before I was fifty percent sure that Li Weiyi was the murderer, but after hearing what Li Weiyi said, there was only a ten percent chance that Li Weiyi was the murderer. Wang Chao was a little puzzled .

He looked at Jiang He, and replied after a moment of thought: “From all aspects of analysis, the words Li Weiyi said are consistent in terms of motivation and timing. He said: The specific details of the killing method and some of the specific details are also consistent with what you and I saw at the scene before.”

Xu Yiman also said: “Yes, didn’t you say that Li Weiyi was the murderer before, why do you say that Li Weiyi is not now? The murderer, I really don’t understand you.”

Jiang He retorted: “The probability is based on all the information. Before there are no additional conditions, the probability is likely to be 100%, but if there is With additional conditions, the probability is likely to drop to zero as soon as possible.”

Xu Yiman was helpless: “Just be happy.”

“Then let me tell you a few points that I think information and inferences can’t match.” Jiang He quickly said.

“First, from the information left at the scene, I have 80% confidence that Wu Guifeng committed suicide. But in Li Weiyi’s words, Li Weiyi said that he killed Wu Guifeng, which is inconsistent with my inference. With that

said, Jiang He looked at the detective who had been beaten by him before: “After seeing the knife stuck in Wu Guifeng’s body, I did an experiment with this detective. The result of the experiment was that if Wu Xiufen He killed him, so the murderer should be holding a knife in his backhand.”

Jiang He picked up a pen beside him and simulated the murderer’s movements in his hand. I saw Jiang He held the signature pen with his backhand: “The side of the signature pen facing outward is the blade, and the side facing me is the back of the blade. Only in this way can the murderer cause such a wound on Wu Guifeng’s body. Moreover, he must master the angle, otherwise with such a stabbing method, the knife is very likely to be cut open.”

Jiang He shook his head: “If it is really Li Weiyi, then why did he use such an awkward one? It’s very strange to kill people in a posture.”

Everyone was silent for a while, and Wang Chao said, “Is it possible that he pulled the knife out of He Huijuan’s body with his backhand, and it is not surprising that he used the backhand to draw the knife. Li Weiyi He also said that he rushed out in a hurry, maybe it was too late to adjust the posture of holding the knife, don’t you also say that Wu Guifeng has the possibility of homicide.”

Jiang He nodded and stabbed himself with his signature pen: “You said it well too. , but the probability of suicide is significantly higher. But as long as it is theoretically possible, anything can happen. Probability theory is a wonderful thing, even if it is as high as 99%, it is not certain.”

“But this is just one of the suspicious points.” Jiang He said again: “According to Li Weiyi, after he heard the movement from the entrance, he immediately went out to check, and then he killed his mother at the entrance. But at the scene, on the floor or even the wall at the entrance, I didn’t see any bloodstains of sputtering. I also didn’t see any footprints on the floor, not a single footprint.”

It was Wang Chao who spoke again: ” When we went there, in order not to damage the scene, we basically stepped over the pool of blood in one step, and the security guards must have done the same. I think there may be spatter-like bloodstains, but Wu Guifeng is still bleeding after that, new ones. The bloodstain has covered the previous bloodstain, which is a high probability.”

Jiang He put down his signature pen: “On the doorknob, there is only a bloody handprint left by Wu Guifeng on the doorknob. After Li Weiyi killed someone, the There should be bloodstains. When he rushed out the door, he left no traces. Moreover, after stabbing Wu Guifeng, there was no blood on his clothes and shoes, which makes no sense.”

The points that Jiang He put forward are indeed difficult to explain, and if this Li Weiyi is not lucky enough to not be stained with blood, then Li Weiyi is not the murderer at all. But the current evidence points to Li Weiyi, and Wang Chao can only consider the former.

Wang Chao said, “Wait, let’s ask together, including where he threw his phone. If he can match these, then basically the case can be finalized.”

Jiang He nodded.

Xu Yiman had been standing by, listening to the conversation between Jiang He and Wang Chao about the murderer, and suddenly a strong curiosity arose in his heart. A simple case can have hundreds of different possibilities, and these people are trying to find the truth among these chaotic possibilities.

“But there is one thing we have to consider.” Xu Yiman cleared his throat and joined the discussion: “You guys, if a person says he killed his wife and mother, think about how much torment he should endure. Especially if this person didn’t kill anyone, but said that he killed someone, and he killed his own relatives, this is even more unreasonable, doesn’t he want to find the real murderer?”

Wang Chao agreed with Xu Yiman’s words. “What you said is very reasonable. Analyzing the psychology of criminals is also a course in our university. In ancient terms, this is a bloody revenge that must be avenged. If Li Weiyi did not do it, then Li Weiyi must not break the murderer. There are thousands of corpses.”

Jiang He dismissed this: “Although you said you have seen someone who can see what a criminal is thinking, but I think that is still an unreliable thing. Especially psychology, That’s just a general experience summed up, and it doesn’t play a big role at all. It’s okay to guess what other people are thinking in this way, but I would never use it in solving a case.”

Wang Chao shrugged: “Using Seeing is believing what you say, and I believe that one day you will meet such a person.”

Jiang He added: “This kind of reasoning is based on a guess. If you use information that is inherently uncertain to infer a conclusion, then the conclusion is based on ambiguous information, and the conclusion may not even exist. , how can we infer the probability of this conclusion?”

Wang Chao and Xu Yiman were speechless, they both knew that Jiang He’s words were wrong, but they didn’t know how to refute it, and there was no way to refute it.

In fact, after all, people are not machines, they are sentient beings. Emotional animals are born with the ability to see through the psychology of others, but there are strong and weak ones.

If that formidable expert is one of the best in this area, Jiang He is basically zero.

The interrogation resumed, this time focusing on a few suspicious points.

Xu Yiman, who had already completed the task, could go back to the city bureau, and now it was almost time to get off work. But Xu Yiman seemed to be interested. At this moment, she really wanted to find out whether Li Weiyi did this case. Regardless of the result or not, she wanted to hear what Li Weiyi would say.

“Li Weiyi, it’s up to you. Tell me in detail how you killed He Huijuan and Wu Guifeng, and restore your actions at the time.” Wang Chao said, and rolled an A4 piece of paper into one. The strip was handed to Li Weiyi.

Li Weiyi took the paper, first grabbed the paper roll with his right backhand, and then stabbed it straight down. Then, in the same posture, he stabbed and pulled down obliquely in a very awkward posture. Seeing this, a big stone in Wang Chao’s heart fell to the ground. He glanced at Jiang He next to him, meaning that Li Weiyi should be the murderer.

Jiang He didn’t speak at the moment, he was just observing Li Weiyi.

Li Weiyi threw the paper roll on the ground and said, “That’s it, is there a problem?”

Wang Chao didn’t answer, but continued to ask, “Where’s the blood on your shoes on your clothes?”

“Throw it.” Li Weiyi replied: “I ran out, but there was blood on my body. Although there was not much blood, I was also afraid, so I went to the unit and changed into a formal suit.”

“Where did I throw it away?” Wang Super asked.

Li Weiyi took a look: “I thought about committing suicide, I wanted to jump into the river and die, but I didn’t have the guts, so I threw my clothes into the river.”

“Where exactly?” Wang Chao asked about this kind of information. very carefully.

“The area on Erlong Street, I can’t tell exactly where it is.” Li Weiyi replied.

Wang Chao continued to ask: “Where did you throw the phone?”

“Forget it, I remember that I threw it not long after I left the community, but I was so scared at the time, I don’t know exactly where I threw it. But I didn’t use force and threw it out. The phone was still intact.” Li Weiyi answered seriously.

“Are you turned off?” Wang Chao asked.

Li Weiyi shook his head: “It’s not turned off.”

At this moment, a criminal policeman came in from outside the door and whispered something in Wang Chao’s ear. Wang Chao nodded again and again, and after a while, Wang Chao let the The criminal policeman looked at Li Weiyi, while he greeted Jiang He Xu Yiman to come out.

“What’s wrong?” Jiang He asked.

Wang Chao closed the door and said, “Our comrades from the criminal police team found out that Li Weiyi’s figure was found in a camera at the entrance of Chengshun Street. Chengshun Street is not far from Li Weiyi’s home. It’s far away, and it takes about 15 minutes to walk there. And this old-fashioned community is open, that is, you can enter from all directions, so there is no camera to see whether Li Weiyi has gone back.”

“However.” Wang Chao looked at the direction of the interrogation room: “This is very telling. The time is about 10:40 in the morning, and the time is consistent. And just now you saw Li Weiyi’s movements, although awkward, but with the direction of the wound. It fits. As for the clothes and the phone, that could be a big deal.”

Wang Chao looked at everyone: “Close the case, and hand over the evidence to the court.” After speaking

, Wang Chao and Xu Yiman shook hands: “Thank you so much, come to play with us when you have time, but I don’t want it to be Because of the case.”

Xu Yiman smiled: “I also hope that I will never have to work, but there is no way. In our city alone, on average, two people are born every day, and two people die every day. Doctor. It’s impossible to rest, of course, so does the forensic medicine doctor.”

Wang Chao sighed, “That’s right, right, Jiang He, I really want to thank you this time, if it wasn’t for you…” But

Wang Chao looked up like this . , where is Jiang He’s figure still there: “No, wasn’t he still here just now, where are you?”

A criminal policeman said, “While the two of you were talking, he left, and he also borrowed three from me. One hundred yuan, said Captain Wang, you will pay him back…”
