Su Cheng said: "Zhang San and Hua Feiyu met for the first time, and they communicated by phone before. Zhang Sanyi went home sweating, I understand the soup, hurry up, or say it's all stolen anyway, then it's a little dirtier and cut the meat. What I don't understand is that with Zhang San's state at that time, how could he have changed his heart so quickly? The police and Hua Feiyu both agreed, and Zhang San went into the kitchen to pour water and cut meat in the kitchen. ”

Fang Ling said: "In the morning, the police arrested someone, and a bad guy admitted that he took the medicine to Zhang San, he said that Zhang San was a rich man at night, and often went to nightclubs to wander around, and specially drugged to take fruit () photos, and gave the photos to the bad guys, and the bad guys sold the photos back to the victims at a high price." However, the police found the four victims provided by the bad guys, and none of them admitted to such a thing. ”

Fang Ling said: "Zhang San is a vegetable seller, but he only sells in the morning, not in the afternoon, take some vegetables to the market in the morning, and go home at noon." ”

Su Cheng asked: "That afternoon, the lawyer contacted him, and he said that there was something, what was the matter? ”

"I don't know. ”

Zuo Luo said: "According to this information, the motive for the crime can still be explained. ”

"These are not important, two points, the first point, Mrs. Hua believes in Hua Fei very much. The second point is that Hua Feiyu is in the current situation, why doesn't she say that Zhang San wants to violate her? She has seen a lawyer, she should change her words, find out that she was drugged, and then she doesn't remember much, let the lawyer deal with it. So my gut told me she wasn't the murderer. ”

Fang Ling said: "Zhang San lives on the fourth floor, and all the stainless steel anti-theft nets are fenced, and the murderer can't fly in or out." The most important thing is, based on Hua Fei's confession, how did the knife go to the bedroom, and how did it go to the kitchen?"

Su Cheng thought for a long time: "I can make up a reasonable reason for how the knife went to the kitchen, how the murderer disappeared, but how did the knife go to the bedroom...... I don't understand it yet. ”

"How does a knife get from the bedroom to the kitchen?" asked Zoro.

Su Cheng said: "Before answering your question, I need Huafeiyu to cooperate with the on-site restoration. ”

Zuo Luo shook his head: "We are looking at the evidence now, and the evidence is like this, and we can't meddle in other people's cases." ”

"It's a minor issue. Su Cheng said: "If Hua Feiyu is not the murderer, this is a closed room murder case." To be honest, even if I confirmed that it was possible for a knife to travel from the bedroom to the kitchen, I couldn't even think of how the knife could get from the kitchen to the bedroom. ”

……

Su Cheng saw his sister for the first time, Hua Feiyu was beautiful, but she was frightened, her pale little face, she was trembling when she spoke, she had not fallen asleep, and her mental state was very bad.

Hua Fei was given special care and placed in a special hut in the detention center, which was built in the detention center, but separated from the detention center and had a separate space. The prosecutor also knew that the arrest was too fast, and provided some good conditions, the most important of which was to guard against the hanged man. Huafei is currently equivalent to house arrest, and the conditions for living and eating are still okay.

Su Cheng was most worried about Hua Feiyu's madness.

Hua Fei pulled his hair: "I don't know, I don't remember, my mind was blank at the time, I didn't know anything." ”

Su Cheng said: "You need to calm down, I have a way to calm down, do you want to try?"

Hua Feiyu nodded.

Su Cheng snapped his fingers and said to the accompanying detention center doctor: "Give her a sedative and let her sleep for a few hours." ”

……

It was already seven o'clock in the evening, and by the way, I had dinner with the prison guards, Zuo Luo and Su Cheng were at the same table, and asked, "Say, where is the key point?"

"I basically know how the knife flies around, the point is that Hua Feiyu's emotions have collapsed, it is the first time she has suffered such a visual impact, and her hands are covered with blood, which makes her pampered definitely unbearable. Flying around was just my guess, though. To be honest, my brain hole is very open, and I can open reasonable logic when I fly around, but there is a hurdle in this brain hole, which overturns this brain hole. Su Cheng said: "Don't ask, now we need on-site restoration, which is very important." ”

"Are you handling this case because of Huafei language, or because of ......?"

"No, if Hua Feiyu is not the murderer in this case, then I think it will be very interesting. ”

"So the direction of your investigation is to follow the bias that Hua Feiyu is not a murderer. ”

"That's right. Su Cheng shook his head: "But there is a hurdle, I can't get over it if my head wants to explode, I may have entered the dark light of logical thinking." ”

"Then you can open a black hole. ”

"It's over, and the brain says that the black hole has done its best. Let's do an on-site restoration first. ”

……

Early the next morning.

In order not to irritate Hua Feiyu and not to use the real scene, the physical evidence team built a shed overnight, as much as possible to be the same as the scene.

Su Cheng encouraged Hua Feiyu: "Don't be afraid, what was at the time, you should be like it, if you can't remember it, you can't remember it clearly, you must tell the truth." ”

Hua Feiyu looked at Su Cheng and nodded: "I know." ”

"Please. ”

Hua Feiyu just wanted to take a step and paused: "Officer Su, in ancient and modern times, Chinese and foreign, unjust cases have always existed, right?"

Su Cheng nodded: "That's right, even in modern times, under the premise of judicial fairness, it has only greatly reduced the occurrence of unjust cases, if it is said that there are 100% unjust cases, it is not ...... There are a lot of coincidences in this world, but don't worry, we are Z7, the best police detectives in the world. ”

Hua Feiyu walked to the mat at the door, the door was closed, and introduced: "I called Zhang San here at ten o'clock, Zhang San said again that there was a key under the mat, and I said that when he came back, he would be as soon as possible." I use my mobile phone to contact a few customers, and I work a lot. ”

Hua Fei said: "About half an hour later, Zhang San arrived sweating profusely, and his whole body emitted a sour smell. ”

The physical evidence team asked, "What kind of smell?"

Hua Feiyu thought for a while: "After sweating, it dries, and the kind that sweats again." ”

Su Cheng dressed as Su San and appeared to shake hands with Hua Feiyu, took the key to open the door, Hua Feiyu entered the room, Su Cheng asked, "Is that right?"

"Yes. ”

Su Cheng turned around and closed the door, took out the key to lock it, shook his head, and said: "No, Zhang San didn't use the key under the foot pad, but the pocket key, there are four, there must be a sound when you take it out, if Zhang San locks the house and turns the key, it is impossible for Hua Feiyu not to find out." So I don't think there's an inner lock. ”

Hua Feiyu sat down, Su Cheng walked into the kitchen quickly, took a glass of water and put it in front of Hua Feiyu: "Lawyer Hua, you drink saliva first, I'll put the meat in the pot and make soup, wait a minute, I'm sorry." ”

Hua Feiyu picked up the water and took a sip of it and nodded, Su Cheng went to the kitchen, Hua Feiyu stood up, took the water cup and walked to the window of the living room to look out, during which he drank a few sips of water, but the cherry mouth, Miss Sven, did not drink much.

Su Cheng came out: "Lawyer Hua, I'll change my clothes first, it's not good if the sweat drips on the documents." ”

Hua Feiyu asked: "Mr. Zhang, do you want to take a shower first, anyway, it's not in a hurry." ”

Su Cheng replied: "It's okay, change your clothes, it's important to get down to business." ”

Su Cheng entered the bedroom, and Hua Fei said: "I waited for about seven minutes, less than ten minutes, I couldn't hear any movement, it was very strange, so I went to knock on the door." ”

The physical evidence team introduced: "The door of Zhang's third bedroom has been replaced this year, and the sound insulation effect is quite good, but the knock on the door must be audible." ”

Su Cheng nodded and asked, "Is the door locked?"

"No, just turn it off. ”

Su Cheng fell on the bed, Hua Feiyu entered the room, cautiously called Mr. Zhang, while approaching, because Su Cheng was wearing dark clothes, sweat and blood were difficult to distinguish, Hua Feiyu put his hand on Su Cheng's back and turned his right shoulder to see Su Cheng's open eyes, he was startled and let go, and then looked at his hand, which was full of blood, and immediately screamed in horror and ran away.

Out of the gate, the person hit the wall opposite the gate, fell, immediately got up, ran a few steps forward, Hua Fei said: "At this time, the neighbor at the end of the corridor opened the door. ”

Zoro looked at the transcript: "That's right, the neighbor's testimony is like this, the neighbor at the end of the corridor was the first to open the door. ”

Hua Feiyu: "At that time, my mind was blank and I didn't know anything. ”

Zorro: "The neighbor's testimony said that a woman was leaning against the wall and yelling, and he hurriedly ran over to ask what was going on, and the woman panicked and pointed to the room. At this time, two other neighbors on the same floor, as well as three neighbors upstairs, came down, a total of six people asked each other: What's the matter, what's the situation? The neighbor in the corridor is called A, and A said, I don't know, I cautiously walked to the door and looked inside, but I didn't find a problem, and several neighbors entered the living room together, walked to the bedroom, and then saw the dead Zhang San. ”

Su Cheng took a stopwatch: "Song Kai appeared as A." ”

Song Kai went to position A, and according to his confession, A was watching TV at the time. Fang Ling took the place of Hua Feiyu, screamed, opened the door, asked Fang Ling, and the neighbors asked on the central staircase, or opened the door to ask, and entered the living room of Zhang San's house together.

"Stop. Su Cheng looked at the stopwatch: "From the time the neighbor heard the scream to the time he saw the living room, there were a total of seventeen seconds, strictly speaking, these seventeen seconds...... Feiyu, thank you for your cooperation, please go back first, you did a good job. ”

Hua Feiyu nodded, and under the supervision of the policewoman, left the physical evidence team.

Su Cheng said: "I am the murderer now, Zuo Luo is Zhang San, and Fang Ling is Hua Feiyu, start." ”

Su Chengren leaned behind the bedroom door, because there was a floor hanger behind the bedroom door, and the base was partly large, so the door could not be completely closed, enough for a non-fat man to hide. Zuo Luo opened the door, did not bump into Su Cheng, closed the door with his backhand, walked to the opposite side of Su Cheng, and opened the wardrobe. Su Cheng walked out, holding a boning knife in his hand, stabbed Zuo Luo in the back, his heart was punctured, Zuo Luo's whole body lost strength, paused for a second, and then Su Cheng pushed it, and Zuo Luo's upper body and part of his lower body fell on the bed next to the wardrobe.

Su Cheng: "This time is blank, I don't know what happened in these seven minutes." Time passed, and then Fang Ling, you knocked on the door as Hua Feiyu. ”

Su Cheng heard the knock on the door, and immediately hid behind the door, holding the boning knife in his hand, Fang Ling saw the corpse, screamed, and ran away. Su Cheng went out of the bedroom door, looked left and right, went to the kitchen, and put the boning knife back in the kitchen. At this time, the voices of the neighbors came, and after Su Cheng leaned into the kitchen, the neighbors entered the living room, looked at the bedroom together, and walked to the bedroom, Su Cheng quietly walked behind them.

Su Cheng: "Are you dead?" Do you want to call an ambulance?"

Zuo Luo nodded: "I understand, you mean that the murderer was already lurking in the bedroom, preparing to kill Zhang San, and the murderer is Zhang San's neighbor." After the neighbor entered the bedroom, he pretended to be a neighbor who came with him and joined in the discussion of Zhang San. ”

"Yes, there is a little correction, he may not have been lurking in the bedroom at the beginning, but Zhang San came with Hua Feiyu, so he could only hide first. Su Cheng replied.

Zuo Luo said: "That's right, this is indeed the ability to send the boning knife from the bedroom back to the kitchen, but the boning knife has been in the kitchen, and the murderer can only hide in the bedroom, during which Hua Feiyu has been in the living room, and it is impossible for the murderer to go through the living room to the kitchen to get the knife." Su Cheng, your brain hole is just. ”

Zuo Luo said again: "Even if Hua Fei is blind, Zhang San is such an adult in the bedroom, he closes the door, he is not dead, someone goes out from the door, and then goes to the kitchen to get a knife and comes back, he doesn't find it at all?"

Su Cheng sighed: "So this is a problem, I thought that Hua Feiyu could give some flaws by restoring the scene, but ......" Su Cheng had to admit that he solved most of the contradictions, such as how to return the knife to the kitchen and how to get out of the murderer. But he couldn't solve it, how did the murderer get the boning knife.

Bai Xue said: "Will the murderer have an identical boning knife and assassinate Zhang San, and then he may want to chase Hua Feiyu to kill him, but Hua Feiyu ran out and alarmed the neighbors, and the murderer went to the kitchen and changed the knife." ”

Song Kai: "How could the murderer come up with a way to get out so quickly?"

Zuo Luo said: "I don't doubt the way to get out, because there are film and television works that use this method of crime." Maybe he hid aside in a panic and found that everyone didn't pay attention to the direction of the kitchen, so he mixed up, and the murderer had time to think. But ......"

Physical Evidence Group Interface: "The medical examiner and we examined the murder weapon, and the murder weapon had two gaps, which were completely consistent. ”

Zuo Luo said: "Su Cheng, assuming you are right, the suspect can only be the neighbor Li Si, a fatal knife, fast and ruthless." Comparing the backgrounds of several neighbors, only Li Si is a doctor, a surgeon, and he has the ability to cut the heart with one stroke. Li Si was also in the neighborhood group at the time. Although the neighbors confessed that they entered Zhang San's house with Li Si, this confession was subjectively deceptive and not credible. Then again......"

Su Cheng smiled bitterly: "I know, I first have to solve the problem of how the knife gets from the kitchen to the bedroom Li Si's hand, and I can't alarm Zhang San, I can't solve it, what do you think?"

While everyone was pondering, Fang Ling opened his mind: "Are Zhang San and the murderer in the same group? The murderer hid well, Zhang San hid from the kitchen to the bedroom, and ......" Fang Ling did not say any more, is Zhang San looking for death? Deliberately partnered with the murderer to kill himself to pit Hua Feiyu? Pork is pork bought by Zhang San, and logic and theory do not make sense.

After a long silence, Zuo Luo said: "I have to admit that the only one who can kill Zhang San is Hua Feiyu." ”

"Yes, only she can do it. Su Cheng nodded, the process was not clear, Hua Feiyu's confession did not involve this aspect, and it was difficult for the physical evidence to restore the course of the incident, but he had the ability to do it only in Hua Feiyu. Unless Hua Fei changes his confession now and provides false testimony to show the existence of a third party. However, Hua Feiyu has insisted on his confession many times, and it is unlikely that the police and the court will accept his new confession.

"Good afternoon, Team Zhou. ”

Zhou Xuan's voice came: "Okay, I heard that the seven groups are coming to smash the field?"

The greeting brother didn't know what to say, so Zhou Duan entered the simulation scene and said, "Zoro, what is the result of the on-site drill?"

Zoro patiently explained the process. Zhou said: "It seems that only Hua Feiyu has the ability to create such a scene." ”
