Su Cheng was very relaxed, in a good mood, and said, "I came to you, not to let you compliment me." I myself think that I am also very powerful, and I also think that Hua Feiyu is innocent, but I am so powerful, why can't I solve this case? I suddenly remembered a word, called back to the basics, Qi Ming, you are a patrol policeman, and you have not been exposed to real criminal investigation work. Bai Xue, you are now in the learning stage, and I know that you have your own opinions on many cases, but you dare not say it. Hua Feiyu's case, I, who you think is an idol, I myself think that a very powerful person can't break it, there is a great possibility, I am bound, and the truth is in front of me. ”

Bai Xue and Qi Ming said they didn't quite understand.

"Taking the Romance of the Three Kingdoms empty city plan as an example, Zhuge Liang and Sima Yi are both old foxes, Zhuge Liang strengthened Sima Yi a little and scared Sima Yi away, because Zhuge Liang knew Sima Yi. When we handle cases, it is difficult to fully understand a suspect, his spirit, his behavior. Suppose the empty city plan is a stunned person instead of Sima Yi, and when he looks at the empty city, he rushes in without saying a word, but he can break the empty city plan. I think I'm in Huafei...... No, in the past few months, I have always felt that my thinking mode has been imprisoned due to my long-term exposure to various more brain-intensive cases, and this time I will find you two chicks to solve this case. ”

Su Cheng said: "The premise is that Hua Feiyu is not a prisoner, how can this be proved, can it be proved that Zhang San may have been killed by outsiders." Did you bring your computer?"

"Brought it. The two of them dug into their bags as if they were doing their homework.

Su Cheng said: "Contact XXX of the physical evidence team, and he will send you a one-hour video of the process of today's on-site restoration, the debate between us, and the hour." As for other information, you can also contact the people in the Evidence Unit, I need you to find out. Remember, this criminal is not a transnational old bird, Bai Xue, you go over there, Qi Ming your side, don't contact each other, let's start working on the question. ”

The two started very obediently, and Su Cheng took Bai Xue's mobile phone to call: "Lady, I'm having fun in the XX nightclub, do you want to come over and catch it...... , Zhou Duan treated my lady as a brute, and I haven't rested for a few days...... I'm sorry, Xuanzi, I was wrong...... Be...... No problem...... No problem......"

It's so boring, Su Cheng went to the nightclub hall, the nightclub is divided into many small departments, there are noisy Di bars, quiet water bars, KTV, performance venues, etc. Su Cheng went to the water bar, sat at the bar, asked for a bottle of mineral water, and listened to the song quietly. Generally speaking, the water bar sister is more upscale than the Di bar, the Di bar is to look at the face, the two of them get together and twist their butts, eye to eye, just have a drink, and then look at the reason why the other party comes to the nightclub, in this era of fire, all that is needed is a platform. Nowadays, because of the popularity of social software, the nightclub business is not easy to do.

The water bar is usually an exchange between the prey and the hunter, a girl sits alone on the side, there will be a gentleman asking the waiter to bring a drink, if the girl is interesting, will raise a glass, and then the gentleman will find an excuse to sit down together and talk to each other. Even if the girl is waiting for someone or other reasons, she can still talk, and the two sides have more to dig out more things besides.

Such a handsome guy sat at the bar for 20 minutes, why was it that only the bar attendant served him mineral water? The reason was that he ordered mineral water, and he looked very boring at first glance. Look at the connotation, who TM has time to read your connotation?

The bartender is very talkative, very observant, and knows if you need to talk, or if you want to be alone. Su Cheng chatted with him: "It turns out that there is a girl here named Ma Ziye, do you know each other?"

"Oh, yes. The drinker wiped the glass and polluted the cup twice: "It didn't dry a year ago, and it is said that it inherited an overseas inheritance and went in style." ”

Su Cheng asked, "Apart from me, is there anyone more strange who has asked you about her?"

"Lately?"

"A year ago. ”

The drinker smiled: "Officer, you're kidding, I have to chat with a lot of people every day, how can I remember the incident of a year ago." ”

Su Cheng said: "I know that you have goods in the cabinet, and someone has been waiting for me to leave the bar, if I guess it's right, it should be someone from Di Bar who wants something...... I don't care if I shake my head, let's give each other a step and be kind, okay?"

The drinker is in his thirties, has seen the world, and is not nervous: "Okay. ”

Su Cheng took Bai Xue's mobile phone, put together some photos of people just now, and then handed it to the drinker: "Who asked?"

"Him. Referring to Liu Mo.

He ...... It seems to have been a few years ago, and it was very special, and I could smell that he was from the police or the relevant department, so I kept an eye out for it and called the night in advance. ”

Su Cheng looked at it from the side, it was a high inspection.

The drinker looked at it for a while and returned the phone to Su Cheng: "There is also a man in his thirties, there is no photo on it." ”

Su Cheng asked: "A man in his thirties, is it later or earlier than you recognize the first man?"

"The front and back feet, the first man had just walked for less than three minutes, and the man in his thirties gave me a few hundred dollars and asked the man what he asked. ”

"Oh?" Su Cheng was surprised that Liu Mo was actually followed, which is not very scientific. First of all, Liu Mo is very capable, and he must be a good hand if he can track him without being discovered, and there are people in Z7 who can do it. Secondly, why did he follow Liu Mo, Liu Mo only asked about Ma Ziye's situation at that time, and he had not yet been in contact with Ma Ziye, so he should not have been discovered at this time, and sent out the stalker so quickly. That is to say, Liu Mo had been suspected before.

But there are contradictions, if they suspect the direction of Liu Mo's investigation, for example, Liu Mo inquired about the murder case of the high procuratorate and obtained some information, and asked Liu Mo to find Ma Ziye, then they know the purpose of Liu Mo's visit to the bar, and they will not send someone to ask the drinker. It is inferred that someone is following Liu Mo, but it is not because of Ma Ziye.

Su Cheng suddenly smiled, and then took five hundred yuan and put it on the table: "I never asked." ”

"Don't worry, I don't dare to offend you. The drinker smiled, watched Su Cheng go back to the box, threw the mineral water bottle into the trash can casually, wiped the countertop, and put five hundred yuan into his pocket by the way. After doing this business for seventeen years, the people in the rivers and lakes have seen too much, and it is best not to provoke people like Su Cheng.

A girl came to the bar and looked at Su Cheng's back: "Who? I can't see a person who drinks mineral water, but it's very generous." Which rich second generation?"

The drinker continued to wipe the glass and said, "Marilyn, forget about this...... How was that last time you hooked up?"

"Paralysis, treat the old lady as a female branch girl, give me 2,000 yuan,, does the old lady care about 2,000 yuan?"

"What about you, if you want to fish for a golden beetle, you have to change places, you have been in the bar for half a year, you have seen a lot, which one will meet in a nightclub and bar and get married emotionally, and not divorce soon? Come here, relax, reduce pressure, and make an appointment when you meet a suitable person. Feelings are very expensive, and no one is so casual. ”

……

Su Cheng returned to the box and clapped his hands: "Okay, sort out the case." ”

Bai Xue had one-sided contact with Hua Feiyu's case, and discussed with Qi Ming for a while, Bai Xue said: "The biggest doubt in this case, why did the kitchen knife go to the bedroom and from the bedroom to the kitchen. Consultant you have raised the knife from the bedroom to the kitchen, the main thing is how the knife is from the kitchen to the bedroom...... I initially guessed that it would be Zhang San who carried the knife with him after cutting the meat. ”

"And then?"

Bai Xue said: "Then I think it's unlikely, it's obvious that Zhang San was stabbed soon after entering the door, Zhang San wanted to hide the knife, and the murderer took the knife, according to what Zhang San was wearing at the time, I don't think the murderer easily got the knife and was not discovered by Zhang San." ”

Su Cheng said: "Zhang Sanzang knife to the bedroom, this is good, I didn't expect it, but as you said, the possibility is not high." Lack of basic purpose. What about Qi Ming?"

Qi Ming said: "I noticed that you said that if there is a murderer in the neighborhood, use the way of consulting you, send the knife back to the kitchen, and people blend in with the neighbors, then there is a good chance that the murderer is Li Si." He was a surgeon in terms of the professions and skills of several of his neighbors. A fatal blow shows that the murderer is very murderous, that is, he wants to die, and with such a mentality, ordinary people will stab the knife continuously, but the murderer does not, which shows that he understands the consequences of this knife very well. ”

Su Cheng nodded: "And then?"

Qi Ming said: "As a surgeon, being bold and careful is the most basic requirement, and as a neighbor, Li Si may know that Zhang San has the habit of putting the key under the foot pad. In my imagination, Li Si had murderous intentions and infiltrated Zhang San's house, but Li Si didn't expect that Zhang San was not alone, and after killing Zhang San, in the next few minutes, Li Si had plenty of time to think about getting out. ”

Su Cheng said: "Go on." ”

Qi Ming looked at Su Cheng and smiled bitterly: "I don't know how to continue." ”

Su Cheng stood up and patted Qi Ming on the shoulder, touched Bai Xue's head by the way, and said, "I already know the truth, but I need to confirm it first, and sure enough, Puyu is the rarest." ”

Bai Xue looked up: "Advisor, what do you mean?"

Su Cheng picked up his mineral water bottle and said, "I originally saw the world from this bottle, no matter how big my brain is, I can only see the world of bottles." If you give me a beer can to see the world, I will naturally see the world of beer cans. My biggest mistake in this case was that I paid too much attention to the murderer's murder methods and the contradiction of moving the knife. Okay, I'll pay the bill, you guys drink more, don't drive. ”

The theory of contradiction is the basic principle of solving the case of the big pineapple, and it is also the core of solving the case. Like a liar, he will tell more and more lies in order to fulfill his lies. Unravel the contradictions, and the clues will be clearer.

However, Su Cheng once questioned the theory of contradiction, focusing too much on the details of the contradictions, rather than looking at the case from a macro perspective, will it lead to too one-sided views. The big pineapple affirmed Su Cheng's doubts. Big Pineapple told Su Cheng that if he carefully studied the Sherlock Holmes deduction method, he would find that there were also misunderstandings in human use. Big Pineapple told Su Cheng that contradiction is a weapon, but you can't just have this weapon.

For most of the past six months, Su Cheng has relied on the theory of contradiction to solve many cases, but because of the victory, he is too limited to the theory of contradiction. In many cases in the past, Su Cheng only investigated contradictions, and the other clues were all Zuo Luo and they went to investigate and visit. From the Five Ninja Case to the present, Su Cheng always felt that he was lacking something, and now he understands that he regards the contradiction theory as the only weapon, and sometimes not only can he not solve the case, but he will also blind his eyes.

……

Li Si was invited to the interrogation room, of course it was not invited to go to the interrogation room, to be precise, the criminal detention notice invited Li Si here, and Fang Ling and the people from the physical evidence team were searching Li Si's home and place of work.

Su Cheng and Zuo Luo presided over the trial, and Su Cheng asked, "Li Si, how is your relationship with Zhang San?"

"It's okay, neighbor, look down and don't look up. ”

Su Cheng asked, "Do you often visit the door?"

"That's basically not, now many people don't like neighbors to visit the door, and I don't like it either, I always feel that others are disturbing your life. ”

Su Cheng asked, "Have you been to Zhang San's house, in the last few months?"

"Maybe, occasionally go upstairs together, say hello, and sometimes go to the neighbor's house to contact a little relationship, after all, such as the owner, the property, the community environment, etc., the neighbors still have to know each other. ”

Su Cheng asked again: "Then have you been to Zhang San's bedroom?"

Li Si shook his head: "I'm not a comrade, how can I go to someone else's bedroom." ”

Su Cheng smiled: "Full of confidence, as a surgeon, you have more time to decide, you believe in yourself." ”

Li Sidao: "I don't know what you're talking about. ”

"This case was originally very simple, and it was basically impossible to prove logically that at the time of the crime, in addition to Hua Feiyu and Zhang San, Zhang Sanjia also had a third party. Although I tried, I found that the location of the murder weapon was too strange. However, there is a turning point in this case, the turning point is Hua Feiyu, Hua Feiyu This girl is very tough, assuming that Hua Feiyu changes her confession, and the lawyer and the prosecutor fight hand-to-hand in court, there is still a chance to win the case, assuming that she changes it, and fights back because she was drugged, then the case is basically over, at least for me. But her tough attitude made me never believe that she was a criminal. Assuming she wasn't a criminal, there must have been a third person in the room. I had to prove how the boning knife went from the kitchen to the bedroom and from the bedroom to the kitchen. ”

Su Cheng said: "I have solved some of them, the murderer is hiding in Zhang San's bedroom, killing people, hiding on one side." Hua Feiyu saw the scene of the murder, frightened, and rushed out of the door. The murderer put the murder weapon back in the kitchen, and when the neighbors swarmed in, the murderer blended in with the neighbors, the murderer knew people very well and knew that the neighbors were shocked at that time, the pace was fast, and it was difficult to remember the details. Coupled with the fact that the murderer and the neighbors discussed the case and used some words that implied that he entered Zhang San's room with them, the neighbors naturally inadvertently committed perjury. ”

Li Si thought for a while: "Mr. Police Officer thinks I killed Zhang San?"

"Yes, I think you hid in Zhang San's room and killed Zhang San. ”

Li Si smiled and asked, "Mr. Police Officer, then how did I get the kitchen knife and kill Zhang San?"

Su Cheng asked rhetorically, "How do you know that it was the kitchen knife that killed Zhang San?"

Li Si replied: "The criminal police cordoned off the scene and collected the blood stains on the boning knife, and we all saw it. ”
