Department Z has been paying attention to this case to see if Su Cheng can solve the case. When he heard that Su Cheng interrogated the trial after two days of investigation, Ding Dong and three other deputy team leaders and Zhou Duan all went to the surveillance room next to the interrogation room to watch the interrogation.

How did A kill someone? He was stabbed. Judging from the bleeding on the scene, he was going to the second floor and came back without leaving any traces. It was impossible to do it. Ding Dong guessed that A might be an accomplice, and his accomplice took action. But Su Cheng said something after the procedure, not what Ding Dong guessed.

The three presiding judges, Bai Xue, Su Cheng and Bald Head.

After Bai Xue finished talking about Quan Heyi, Su Cheng asked, "Xiao a, how does it feel to kill someone?"

"kindness?"

"Although I have been a detective for so many years, I have never killed anyone. When a man gets angry, blood splatters five steps, and when an emperor gets angry, blood flows thousands of miles. There are more people holding pens than those holding swords."

Xiao A was only three days after he was discharged from the hospital. He looked pale and asked, "I killed someone? I didn't."

Su Cheng asked: "Do you like magic?"

Xiao A was stunned and thought for a while and replied: "I've been a little interested in magic recently."

“When day starts?”

"It's just a general interest, searching for magic information online, etc."

Su Cheng smiled and Xiao A felt a little nervous. Su Cheng said: "Actually, in this case, I am very surprised that one thing is why you were hit."

"Ah?" Xiao A didn't understand what Su Cheng meant at all.

Su Cheng looked at the bald head and said, "Mything is very abnormal psychologically. Your ex-girlfriend heard that you were getting married suddenly, and she was very angry. She was on duty and carried a steak knife. The total length of the steak knife was 24 cm and the blade was 10 cm long, which was quite sharp. This is the first abnormal point, but considering her temper, this behavior can be regarded as a normal behavior."

"Your ex-girlfriend broke into the living room of the villa and accused and questioned you. You felt guilty and comforted her, hoping that she could talk to you alone. She took out a steak knife and stabbed it from top to bottom into your left chest against the armpit. The blade was completely inserted, leaving only the hilt. Considering that the piece was all flesh and no bones, it was normal to insert it completely. The abnormal thing is, why did she only insert it with you?"

Xiao A asked in a puzzled way: "Is one knife not enough?"

The bald man said: "Maybe, it may not be enough. If it is enough, her reaction will be wrong. She slashed ten centimeters deep, and she was unclear about the human body structure. Normally, you will be half a life after this knife. But she was still very angry and turned around and left. With the blocking of the lawyer and the nanny, and being controlled by the lawyer, she still struggled desperately. She did not collapse or appointed... This state should be a state that could only be blocked before stabbing you, but in fact it was a state that could only be stabbed after stabbing you."

"What... what is this?" Xiao a didn't understand.

Su Cheng said: "I will analyze it for you. The exclusion method is, who may kill someone. The first suspect, the ex-husband of the deceased, came to borrow money, but heard that his ex-wife held a banquet and got married, so he waited at the back door. If he killed someone, one might be anger and kill someone, but he might not be in the back door for so long. Another might be an attempted borrowing money, and he was so angry that he was angry. But the deceased was in a sleep state and did not say he would not borrow money, so the ex-husband might be infinitely close to zero."

Su Cheng said: "The second is the nanny. Can nanny kill people? Maybe, but if the nanny wants to kill people, it is also the first to kill you. You have lived in the deceased's house for more than two months. If the nanny really wants to kill people, there are countless opportunities. Why should you wait until you get a marriage certificate before taking action? And killing the deceased will make you the one she hates the most? If it is the nanny who argues with the deceased, it is understandable to kill people angry, but as mentioned earlier, the deceased is in a sleep state and it is impossible to argue. Therefore, the nanny may be close to zero."

Su Cheng said: "The lawyer killed someone. The lawyer always proved that he had not entered the second floor. To tell you the truth, they deliberately ignored you and called an ambulance slowly. This was beyond your expectations and almost died. I met the lawyer last night. He admitted that he deliberately controlled your ex-girlfriend to delay time and make everyone forget that there are still injured people. It doesn't matter. He has no obligation to treat others. The point is that the lawyer only has a little gap, that is, after you are taken away by the ambulance, you can sneak to the second floor to commit the crime while the nanny is not paying attention. But as a lawyer, he should know how much the risk of doing this is. The nanny may see him downstairs in the living room or backyard at any time. The police patrol car is not sure where it is, maybe it will arrive in one minute? So the lawyer's possibility of killing someone is infinitely close to zero."

Su Cheng: "Where is your ex-girlfriend killing someone? This is impossible. According to the time calculation, she arrives at the community and stabs you. It ruled out that she is lurking in advance. Maybe there is a few minutes left, but there is an ex-husband at the back door. If you want to go up the stairs at the front door, you must pass through the living room, and you and the lawyer are in the living room. She can't kill anyone."

Su Cheng said: "So you are the only one left, and it seems that you can't kill people. You only have about three minutes to kill, just when your girlfriend is stinging outside the gate. Because you were hit by a knife, logically speaking, you can't kill people without leaving any traces. But you killed people."

Xiao A was very nervous: "Since it is impossible, how could it be that I killed someone?"

Su Cheng said: "Because you didn't get a knife, yes, your ex-girlfriend used a magic knife or a fake knife. To be honest, I haven't confirmed this yet. What the lawyer saw was the hilt of the knife that was infiltrated into the chest. At that time, your right hand was placed on the hilt of the knife blocking his sight. I think the lawyer actually didn't see clearly, which was a basic psychological hint. Next, your girlfriend wanted to drag them away, so she deliberately threw things angrily at the door. The nanny near the door stopped working and subconsciously intercepted her. The two sides were fighting outside. The nanny could not be the opponent of the young man, so the lawyer had to go out. At this time, your girlfriend must buy you enough time to bite and grab. I calculated that thirty seconds was enough. Your girlfriend exceeded the goal and almost killed you in three minutes."

Su Cheng: "I think you have two plans. The first plan is that your girlfriend drags them upstairs and kills people, go downstairs and stabs yourself. Because you are still alive, you cannot accurately identify your wounds through an autopsy. The second plan is, what should you do if your girlfriend doesn't drag them? It doesn't matter, you go upstairs and kills people, and then return. When you hear a prompt or a sound in the living room, you insert yourself into the stairs, indicating that you have reached the entrance of the stairs, but you haven't walked forward. Then you will return to the living room as much as possible and use blood to contaminate the evidence that you have not bleeded upstairs. Of course, the second plan has some flaws, but you can implement it even if you are lucky because the knife is not pulled out, and the forensic doctor cannot give a definite answer. This is related to your exercise, blood pressure, etc. You just need to pull out the knife during the downstairs."

Su Cheng said: "The most powerful thing in this case is your ex-girlfriend, no, it's your girlfriend. It's ruthless enough, you are all ruthless. In order to escape suspicion, one was killed and the other was in jail. I confirmed early in the morning that you conspired with your girlfriend. But I need evidence. The evidence is in your daily life."

Su Cheng: "There are several difficulties when you want to implement this plan. The first difficulty is that a fake stab cannot be seen by others. Your online record has already explained, so I won't say much. In fact, your girlfriend plays magic videos more than you. You must practice it many times. You also used your body to block the sight of others. The second difficulty is that this stab must be stabbed, but the steak knife will really kill people. This stab must be cruel enough and not die. After all, it is a steak knife. If you stab yourself, you cannot stab it on the ribs. If you stab it on the ribs, you may not stab the blade. There is another possible slippery knife, which not only hurts your life, but also is completely different from the wounds seen by the lawyer. The criminal police team investigated the background of you and your girlfriend. Without a medical background, how did you do it?"

Su Cheng: "From your girlfriend's communication records, we learned that she and her cousin, who is an intern in the hospital, have frequently communicated frequently in the past two months. I have never looked for her cousin, and I guess her cousin will tell me that your girlfriend asked about relevant knowledge. There is only one point of the left breast meat, and the shoulders are between the ribs. There are mostly muscles in that position, and the damage is still quite great with a toothed steak knife. But your girlfriend is so cruel. You can know how cruel she is from the time she is willing to go to jail for more than three years to cover up her crime."

Su Cheng said: "The highlight is the most important point. I don't think you have the ability to arrange this case. It's not that you look down on you. It's true that you have no criminal record and no relative has a serious crime. How did you think of this method of crime?"

Xiao A looked at Su Cheng and could already hear his breathing sound.

Su Cheng said: "The Nile murder case in the autobiography of Big Pineapple (the case solved by Polo in the novel written by Agatha Christie, which also solved the famous Oriental Train Murder case, etc.). Big Pineapple has few fans in China. Although the autobiography is translated, its sales are very low. The Nile murder case is quite different from this case, but the main body is the same. A partner attacks B and pretends to be seriously injured and cannot commit the crime. Then B partner commits the crime and then harms himself."

Su Cheng picked up the computer on the desk and opened it: "Your girlfriend has a record of borrowing the autobiography of Big Pineapple in the library. The Nile murder case is among them. By this time, I have 100% sure who the murderer was."

Su Cheng put down the computer: "I know you are going to struggle to death. I ask, do you have evidence? Actually, I sympathize with you very much. I am willing to give you a chance to surrender. Why do I sympathize with you? Because I know that it is much more than you think. I know that although you don't like the dead in your heart, you are also moved by the true feelings of the dead. In addition, the dead are indeed quite rich, which can greatly improve your quality of life in the future. Unfortunately, you have a very cruel girlfriend." Su Cheng glanced at the bald head. If you say the subordinate and the leader wrongly, then you will be embarrassed next. When Su Cheng was confident of taking the suspect, he was too lazy to collect evidence.

The bald man smiled confidently.

Su Cheng said: "Come on, young man, tell me your answer."

Xiao A smiled helplessly and said, "That's right, I killed people."

Xiao A is a boy with no opinion. At first, he felt that it was not good to be close to the deceased, but he felt that life was good. But he couldn't avoid his girlfriend. His girlfriend had a cat and liked it very much. When they were in love, Xiao A went to his girlfriend to tease the cat and was caught by the cat. Xiao A went to get rabies vaccine and returned to the downstairs and saw that the cat had fallen to death downstairs. His girlfriend said that the cat jumped to the window and thought he could fly. At that time, Xiao A didn't go to his heart.

After Xiao A and the deceased were found out by his girlfriend, his girlfriend asked him, do you know how xx (the name of a kitten) died? Xiao A said he didn't know, and his girlfriend said that because it hurt my favorite person, I threw it out. If you want to choose her, I will not die by myself.

Xiao A was worried. After two days, his girlfriend looked for Xiao A and told Xiao A that he had a way to make Xiao A very rich and not have to be angry with the old woman. Xiao A was usually hard to say no to others because of his surname, otherwise he would not be seduced by the deceased. In addition, his girlfriend had been aborted twice for himself and was very nice to him, so he couldn't say something, so he didn't dare to say that he thought it was better to break up.

At first, Xiao A refused, but his girlfriend had been working hard to improve the details, and bought a magic knife with a handle close to the steak knife at the magic store. As long as Xiao A put away a steak knife in advance, he was pulled away by an ambulance and hid the magic knife, and everything was perfect.

The lawyer and the nanny deliberately did not rescue Xiao A, which caused Xiao A not to deal with the magic knife as soon as possible. During the first aid, Xiao A's mother arrived, and Xiao A secretly asked her mother to take away the magic knife that she folded and put in her pants pocket. Xiao A could have this surname and naturally couldn't separate her mother from her mother, so her mother of course did as she did. At that time, his mother didn't know what the situation was, so she temporarily buried the knife in the soil of the flowerpot at home. A few days later, she visited Xiao A and threw the knife into Qinghu near her home. These were only known afterwards.

Xiao A was finally persuaded by her girlfriend that she could get the property of the deceased, and she didn't have to cooperate with the deceased to be a novice. Afterwards, she could go abroad to be a casual rich man, so why not do it? He thought that this was good, and that was good.

After Xiao A's explanation, the bald head said: "There is a question I want to know. Have you hesitated when you killed someone?"

Xiao A nodded: "I hesitated, but when I thought that xx (girlfriend) had done something that had to be jailed, I would not turn around. If I didn't kill her, xx explained to the police that I had conspired with her, then xx (the deceased) would not forgive me. I would lose everything. So at that time, I had a voice in my heart, I had to kill her, I had to kill her..."

The bald man said: "You are more willing to marry the rich and the dead than the poor, right?"

Xiao A smiled bitterly: "Yes, but she told me that I can not only live a wealthy life, but also a wealthy life in Meda. I have been with her for the past few months, and there are also happy people and unhappy people. Her desire for control is very high, so when xx proposes to kill her, I already agree in my heart."

The bald man said: "You should have proposed to break up at that time."

Xiao A said: "But her proposal is very 'stock'."

The bald man asked with a smile: "Didn't you expect that with your girlfriend's surname, you will be completely controlled by you after she is released from prison? According to my speculation, she must have evidence of your conspiracy to commit the crime. You like women with strong control because you lack opinions. Such women can bring you a sense of security..." Also because of Xiao A's surname, when Su Cheng basically said that the situation was right, he also gave up resistance.
