After the district prosecutor withdrew the case, the Newtang police dispatched police detectives to intervene in the investigation. The initial investigation believed that the murderer was Zhao Liu, who had an affair with Zhang Po. The reason why Zhao Liu's wife found out that Zhang Po was injured was because she went to arrest the female cadre, and Zhao Liu's wife thought that Zhao Liu was at Zhang Po's house. The neighbors all know that Zhang San is a chess idiot. Zhao Po thinks that every time Zhao Liu takes advantage of Zhang San and Wang Wu to play chess, he goes to Zhang's house to go on a date with Zhang Po.

Zhao Liu did not admit that he hurt others, but admitted that he went to see Zhang Po before the crime, on the grounds that Zhao Liu suspected that Zhang San and Zhao Liu's wife were having an affair.

Zhang San admitted that he had an affair with Zhao Liu's wife, but insisted that Zhao Liu had an affair with his wife, and he and Zhao Liu's wife took revenge on them before they were together.

In this report, the relationship between the views of each person in each household and the views of others is detailed, and each person's views on the relationship are subjectively stated.

According to the regional surveillance, there were no strangers in the area before and after the crime, so the possibility of the killer among these people is extremely high.

After withdrawing from the case, Qin Lan did not give up. He began to analyze everyone's chances of committing crimes, and first excluded Zhao Liu, Wang Wu, and Li Si's wives. Zhao Liu left Zhang's house before his wife was injured, went to a nearby commissary to buy a pack of cigarettes, and had a drink with the owner of the commissary. Wang Wu had Zhang San testify. After Wang Wu came out of the bathroom, he entered the living room, and the main entrance of the living room was facing the courtyard of Li Si's house, and he saw Li Si's wife not far away shaking her hair wet in the yard.

After a detailed analysis, Qin Lan found that only Zhang San and Zhao's wife had the opportunity to commit the crime, and at the same time, the possibility of Zhang Po self-harming could not be ruled out.

Detective Niutang has a similar opinion to Qin Lan, and the two sides have investigated together for a week, but they have never been able to prove who is the murderer. Qin Lan analyzed the motive and believed that only Zhang San had the motive to kill. If Zhang Po wanted to commit suicide, she would not choose such a bloody way. Zhao's wife was with Zhang San in order to take revenge on Zhao Liucai, and in the absence of quarrels and fights, the possibility of Zhao's wife suddenly hurting Zhang's wife is very low. Therefore, Qin Lan insisted that the murderer was Zhang San, but she couldn't explain why Zhang Po was very determined to prove that the person who hurt her was not Zhang San.

......

The first thing Yuan forgot to pay attention to was what the contradiction between Zhang San and Zhang Po was. From the descriptions of both parties, it can be known that before marriage, Zhang Po was very satisfied with Zhang San's only hobby. But Zhang Po didn't expect Zhang San's chess addiction to be so big, and she even didn't hesitate to take a plane to meet chess friends in other places, which was incomprehensible in Zhang Po's opinion.

Zhang San has a bunch of precious chess books, which he reads over and over again every day. I'd rather play chess and study by myself than talk nonsense with Zhang Po. At home, Zhang San never touched housework except for thinking that Mrs. Zhang's food was unpalatable and cooking by herself. In his words, it was clean and didn't need to be cleaned.

Zhang San thinks that Zhang Po has no other strengths except for housework. Talkative, mean-spoken, unpalatable cooking, and even made himself unable to get off the stage in front of his chess friend Wang Wu many times, and intensified it a month ago, warning Wang Wu not to play chess with him again.

Zhang Po admitted that Wang Wu was an old bachelor, in poor health, and lived on relief. Every day is just playing chess. What annoyed Zhang Po the most was that she clearly saw Zhang San and Zhao Po in Wang Wu's room, and she broke in and was stopped by Wang Wu, resulting in the failure of the arrest operation. In Zhang Po's view, Wang Wu was the culprit who caused Zhang San's fall.

Yuan Forget believes that he is incapable and unable to solve this case based on the information. At most, it is reasoning, a reasonable reasoning process and result.

......

Ward was the first candidate to enter the interview room.

Facing the chief and deputy examiners, Hua De maintained his poker face, put the information on the table, and said: "There are three doubts in this case, the first point: why Zhang Po can't judge the identity of the murderer. The second point: why was Zhang Po only stabbed once. The third point: Why did Zhao Po, who had an affair with Zhang San, testify against Zhang San, she insisted on saying in her testimony that Zhang Po said that Zhang San stabbed herself. ”

Huade: "Based on the above suspicions, I think Zhang San is the murderer. After the incident, Zhang Po did not want her husband to go to prison and wanted to protect her family, so she made perjury. There is no one with a head covered at all. I guess that when Wang Wu went to the toilet, Zhang San went home to drink water or pick up something, and stabbed Zhang Po after a verbal altercation with Zhang Po. Zhang San was very nervous and immediately returned to Wang Wu's house, hoping that Wang Wu could testify for himself and prove that he was not at the scene. ”

Hua De: "According to Wang Wu, after he came out of the bathroom, Zhang San used the bathroom, I think it will be to clean up the blood stains? Since the victim is not dead, I don't know the knife edge and other problems, so I can't tell whether there are blood stains splashed on the murderer's body." The murderer stabbed Zhang Po in the abdomen from the side, Zhang Po subconsciously covered the knife and pressed the wound, and it was possible that Zhang San's body would not be splashed with blood. Maybe there was some blood on the hand. The person did not die, and it is difficult to simulate the situation from the shape of the knife wound.

Walter was a little distressed by the bloodstain statement. It is understandable that there is no blood on the murderer's body, and there is no blood on the small arms and hands, so it needs to be a character.

In Huade's statement, Qin Lan took a hard card and listened while writing, and after Huade finished speaking, Qin Lan stood up and shook hands with Huade: "It's a good thing." "I didn't say good, I didn't say bad, please ask the security guard outside the door to send Huade to the restaurant to wait.

Lin Mei, the glasses woman sitting on the side, said: "Some doubts have been found, but there are problems with judgment and analysis." ”

Qin Lan exonerated Huade: "Just relying on materials to find suspicious points, his ability is remarkable." He simply did not have time to verify his suspicions, and the statement he chose was the most likely scenario in his own judgment. I'm happy with him, what about you?"

Lin Mei: "I agree. Uncle, would you like to invite your apprentice to appear?"

Qin Lan: "What's the matter, do you have thoughts about my apprentice?"

Lin Mei: "He's from the Detective Society." ”

Qin Lan: "What?"

Lin Mei: "I want to know the contact information of his colleagues. ”

Qin Lan asked: "Zhao Wu, didn't you assist in filming the show together after breaking through the game?"

Lin Mei: "......"

Qin Lan: "That's a scumbag." ”

Lin Mei had a headache: "I know, but I like it." ”

"The scumbag means: I know you like it, but he won't take you to heart. "Otherwise, you won't be called a scumbag. Qin Lan took the walkie-talkie: "301, come in." ”

......

Yuan Forget sat down, and Qin Lan asked, "What clues or suspicious points have you found?" ”

Yuan Forget replied: "I comprehensively investigated the later stage and found only one contradiction. In the later investigation, the detective made a record of Zhao Liu's wife, and Zhao Liu's wife insisted on what she heard. She heard Zhang Po say that Zhang San stabbed her. Zhang Po completely denied this statement, and said that the person with the face would definitely not be Zhang San, because she knew Zhang San when he turned into ashes. ”

"At least four suspicions, you find one. Qin Lan was in a bad mood and said casually: "Who do you think is the murderer?"

"Wang Wu. ”

Qin Lan was stunned: "Wang Wu?"

"Yes. ”

Qin Lan: "Do you think that in the later investigation, the transcript of Zhao Liu's wife is the only suspicious point with contradictions. And then the murderer is Wang Wu? What kind of logic is this?"

Yuan Forget didn't dare to speak, not sure if Qin Lan was prompting him. Qin Lan: "What about you?"

Yuan Wangdao: "I've been analyzing why Zhao Liu's wife insists on this statement. The first possibility is that Zhang Po really said that the person who stabbed her was Zhang San, I went back to look through the transcript and found that Zhang Po was questioned as soon as she became conscious after the operation, and she told the police that the murderer was definitely not Zhang San. I don't think Zhang Po has much room to think, and she doesn't have the opportunity to accept Zhang San's forgiveness and pleading, and Zhang San always insists that she is not the murderer in her transcripts and confessions. The police also did not find any blood stains on Zhang San's clothes, and there were no blood stains on his hands. Unless Zhang San is lucky, Zhang Po forgave Zhang San in anesthesia, and Zhang Po straightened out her train of thought in anesthesia, Zhang San is not a murderer. ”

Qin Lan said: "Why do you say that it is Wang Wu? Wang Wu went to the toilet for eight minutes, and Zhang San had time. Zhang San went to the toilet for a minute, and Wang Wu flew over? Did you have your brain eaten by zombies?"

"No, I first have to solve the question of why Zhao Liu's wife insists on taking notes. Yuan forgot to say: "I just overthrew Zhang San as a murderer, and only Zhao Liu's wife can lie." Zhao Liu's wife had an affair with Zhang San, and the two did not say whether they had feelings or not, but they both shared the same hatred. Coupled with the fact that the injured person is not dead, why did Zhao Liu's wife bite Zhang San to death?"

Qin Lan couldn't understand it anymore: "Ah, yes, why?" Sure enough, a hundred people have a hundred thoughts.

Yuan Forget: "It is impossible for Zhao Liu's wife to frame Zhang San from any angle, but Zhao Liu's wife did frame Zhang San. I drilled into the horns for a while, and I found out that Zhao Liu's wife framed Zhang San, but instead protected Zhang San. She insisted on taking notes, and the police had to break through Zhang Po around this contradiction, and Zhang Po bit Zhang San to death, and the police thought that one of them must have lied. ”

Qin Lan didn't understand even more: "Didn't you say that Zhang San couldn't be a murderer? Why did Zhao Liu's wife protect Zhang San?"

Yuan Forget: "Zhang San has always been the number one suspect. But the most important witness, the victim Zhang Po, decided that it was not Zhang San, and the evidence was useless. ”

Qin Lan: "Then what?" He was about to beat people.

Yuan Forget: "Therefore, I think that the murderer is Wang Wu." ”

Qin Lan didn't spit out a mouthful of old blood: "What does it have to do with Wang Wu?"

Yuan Forget: "Zhao Liu's wife is Zhang San's good friend, and Wang Wu is Zhang San's close chess friend. Since it is impossible for Zhang San to hurt Zhang Po, and Zhao Liu's wife didn't have time to change her clothes after hurting people, only Wang Wu was left. The evidence of Wang Wu's impossible crime was provided by Zhang San, Wang Wu was not examined for bloodstains, and the information showed that Wang Wu and Zhang Po had a conflict. Therefore, I think it was Zhang San who asked Wang Wu to kill someone, and Wang Wu was afraid to run away after stabbing him. ”

Yuan Forget: "But Po Zhang didn't die, which made the two of them more passive." Sai Weng lost his horse and knew that he was not blessed, and Zhang Po proved that Zhang San was not the murderer. ”

"Wait, then Zhao Liu's wife won't protect Zhang San. ”

Yuan Forget: "It is divided into two stages, the first stage: Zhao Liu's wife and Zhang San are on good terms, and they should feel Zhang San's impatience and murderous intentions towards Zhang San. Zhao Liu's wife found the scene and immediately determined that Zhang San did it. The sentence that Mrs. Zhang didn't say was added by Zhao's wife. Why? In order to show Zhao Liu that he has nothing to do with Zhang San. ”

In the second stage, Mrs. Zhang proved that it was not Zhang San, so Zhao Liu's wife insisted on confessing and confusing the police. On the one hand, he also showed his break with Zhang San. Because of the case, after his personal relationship with Zhang San was exposed, he used his actions to show his loyalty to Zhao Liu. On the other hand, it is the so-called protection of Zhang San. Don't let the police dig towards Wang Wu. ”

Qin Lan didn't speak for a long time: "You go out first." Yuan forgot to dissect everyone's mentality and thoughts at that time. For example, Wang Wu, he used the knife, but he couldn't get around the level that he hadn't killed anyone, and he didn't make up the knife.

The most complicated thing is a series of psychological changes in Zhao Liu's wife, and Qin Lan was dumbfounded for a while.

"Oh. Yuan Forget stood up, couldn't judge Qin Lan's expression, and left the room.

Qin Lan looked at Lin Mei: "How do you count this?"

Lin Mei: "He only found one question, but he solved the case." In fact, it was indeed Wang Wu and Zhang San who colluded to attack Zhang Po. It's just that there are some mistakes in the details. Uncle, what do you think?"

Qin Lan: "I like his analysis, he has his own way of thinking. I am used to finding all the doubts, the contradictions and then reasoning and solving all the doubts. He grabbed a suspicious point and stalked him, and found a logic for him to solve the doubt. But this logic is not right. After the truth was revealed, Zhao Liu's wife confessed that she was not sure if she had heard Mrs. Zhang say that. According to psychologists' analysis, Zhao Liu's wife preconceived that it was Zhang San's mother-in-law, and she may have made up this sentence in her subconscious. Yuan Forget was only a small part right. ”

Lin Mei: "The result is correct. ”

Qin Lan: "But the process is wrong. ”

Lin Mei said: "Yuan forgot to analyze the details of Zhao Liu's wife, he doesn't seem to be an analytical detective. Did you find it? The main reason why he testified against Wang Wu was the opportunity to commit the crime. Zhang San and Wang Wu both had conflicts with Zhang Po and both had motives to kill. Wang Wu did not become a suspect because of Zhang San's testimony. In line with a famous saying of Sherlock Holmes: what is left is the truth, even if it is impossible. ”

Lin Mei: "Among the suspects, the only ones who have the opportunity to hurt people are Zhang San and Zhao Liu's wife. But Zhang Po proved that it was not Zhang San, and Zhao Liu's wife had no time to change her clothes, which meant that there was no suspect. Yuan Forget caught a suspect out of the non-suspects. I don't think Yuan is a detective in the mainstream tradition, but he is a person who has brains, can think, and is willing to think. If he is ten years younger and someone cultivates him, he will be a detective in ten years. ”

Qin Lan does not deny this. From the time he met Yuan Wanglai, he witnessed Yuan Wang's gradual transformation from a physical thug type to an intellectual thinking type. That is, seeing Yuan Wang's potential, without Ye Wanniang's persuasion, Qin Lan took an apprentice for a month for the first time.

Looking at the previous dinner battle, Yuan Wang's basic skills are very poor, and his observation and memory are not outstanding. But in one competition, he took the lead, which showed Yuan Wang's ability to digest information. This ability was honed by Yuan Forget when he was a policeman and a hunter.

Qin Lan: "He is my apprentice, objectively speaking, even if I don't know him, I will let him pass, because I am looking forward to his next stage of performance." ”

Lin Mei nodded: "That's what I think...... Oops, forgot to take the number. ”

Qin Lan: "Sai Weng knows if he loses his horse. ”

Lin Mei smiled and didn't raise the bar. You are not a woman, how can you know the charm of a scumbag?Not a man, why is it difficult for vixens to be more popular than women of good families.
