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

He was stabbed, and judging from the blood shed at the scene, he was going to the second floor and coming back again, leaving no trace, it was impossible to do it. Ding Dong guessed that A might be an accomplice, his accomplice's hand. But Su Cheng said a word after the procedure, not as Ding Dong guessed.

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

After Su Cheng waited for Bai Xue to finish talking about Quan Heyi, he asked, "Little A, how does it feel to kill someone?"

"Huh?"

"I've been a detective for so many years, but I've never killed anyone. The puppet was angry, the blood was splashed in five steps, and the emperor was angry, and the blood flowed thousands of miles. There are far more people who take a pen than they do with a sword. ”

Xiao A was discharged from the hospital for only three days, his face was pale, and he asked, "I killed someone? ”

Su Cheng asked, "Do you like magic?"

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

"From what day?"

"It's just a general interest.,Search the Internet for magic information and so on.。 ”

Su Cheng smiled, Xiao A's heart was furious, and Su Cheng said: "Actually, in this case, I am very curious about one thing, why did you get stabbed." ”

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

Su Cheng looked at the bald head and said baldly: "Your ex-girlfriend's knife is very abnormal psychologically. Your ex-girlfriend was very angry when she heard that you had a surprise marriage, and she was on duty with a steak knife with a total length of 24 cm and a blade length of 10 cm, which was quite sharp. This is the first thing that is abnormal, but given her temper, it can be considered normal. ”

"Your ex-girlfriend broke into the living room of the villa, accused and questioned, you felt guilty in your heart, comforted her, and hoped that she could talk calmly with you alone. She pulls out the steak knife and stabs it into your left chest against your armpit from top to bottom, the blade of the blade is fully inserted, leaving only the hilt. Considering that piece is all meat and no bones, it is normal to insert it completely. What's not normal is, why did she only stab you once?"

Xiao A wondered and asked, "Isn't one knife enough?"

The bald head said: "Yes, it may not be enough." If enough, her reaction is not right, she stabbed ten centimeters deep, she does not know the structure of the human body, it seems that normally, you will go to half a life under this knife. Still angry, she turned away, and struggled with the lawyer's and babysitter's obstructions, and the lawyer's hands in possession. No collapse, no appointment...... This state should be a state that can only exist before you are stabbed, but in fact it is a state that can only exist after you are stabbed. ”

"This ...... What is this?" Little A didn't understand.

Su Cheng said: "I'll analyze it for you, the elimination method, who can kill someone." The first suspect, the deceased's ex-husband, came to borrow money, but heard that his ex-wife was holding a banquet to get married, so he waited at the back door. Suppose he kills, one could be a furious killing, and won't be in the back door for that long. There is also a possibility that he attempted to borrow money and killed people in anger, but the deceased was asleep at the time and did not say that he would not borrow money, so the ex-husband's murder may be infinitely close to zero. ”

Su Cheng said: "The second is the nanny, can the nanny kill someone? Maybe, but if the nanny wants to kill someone, she will kill you first." You have lived in the deceased's house for more than two months, and if the nanny really wants to kill someone, there are countless opportunities, so why wait until you get a license to get married? And if you kill the deceased, won't it fulfill the person she hates the most? If the nanny and the deceased argue, it is understandable to kill in anger, but as mentioned earlier, the deceased is asleep, and it is impossible to argue. So babysitter killings may be close to zero. ”

Su Cheng said: "The lawyer kills people, the lawyer always has witnesses to prove that he did not enter the second floor, and to be honest with you, they deliberately ignored that you were stabbed and called an ambulance slowly, which was unexpected by you and almost died." I met with the lawyer last night and he admitted that he was deliberately controlling your ex-girlfriend in order to stall for time and make everyone forget that there are injuries that you need medical attention. It doesn't matter, he has no obligation to treat others, the point is that the lawyer only has a little space, 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 risky it is, the nanny may see him coming downstairs in the living room or backyard at any time, and the police patrol car is not sure where it is, maybe it will be there in a minute? ”

Su Cheng: "What about your ex-girlfriend murder? This is impossible, according to the calculation of time, the time for her to arrive at the community and stab you is about the same, which excludes the possibility that she is lurking in advance, maybe there are a few minutes of space, but there is an ex-husband at the back door, and you must pass through the living room to go up the stairs at the front door, and you and the lawyer are in the living room." There's no way she's going to kill either. ”

Su Cheng said: "So you are left, it seems impossible for you to kill, the time for you to kill is only about three minutes, that is, when your girlfriend is splashing outside the gate." Because you've been stabbed, logically speaking, you can't kill someone without leaving a trace. But you kill people. ”

Xiao A was very nervous: "Since it's impossible, how can it be that I kill someone?"

Su Cheng said: "Because you didn't get stabbed, that's right, your ex-girlfriend used a magic knife or a fake knife, to be honest, I haven't confirmed it yet, what the lawyer saw was the handle of the knife that didn't enter the chest, and at that time your right hand was on the handle of the knife to block the view." I don't think the lawyer actually saw it clearly, and that's a basic mental hint. Next, your girlfriend wants to drag them away, so she deliberately threw something angrily at the gate, the nanny near the gate quit, and subconsciously wanted to intercept her, the two sides scuffled outside, the nanny can't be the opponent of the young man, and the lawyer has to go out. That's when your girlfriend has to buy you enough time to bite and scratch. I calculated, thirty seconds is enough, your girlfriend exceeded her goal, three minutes, and almost killed you. ”

Su Cheng: "I think you have two plans, the first plan is that your girlfriend drags them upstairs, you go upstairs to kill people, go downstairs, and stab yourself, because you are still alive, so you can't accurately identify your wounds through an autopsy." The second plan, what if your girlfriend doesn't hold them back? It's okay, you go upstairs, kill someone, and then come back. When you hear a cue or a sound in the living room, you stab yourself to indicate that you have reached the top of the stairs, but you are not moving forward. Then you'll go back to the living room as much as you can, and use blood to contaminate the evidence that you didn't bleed upstairs. Of course, there are some flaws in the second plan, but if you are lucky, you can implement it, because if the knife is not pulled out, the forensic doctor will not be able to give a definite answer, which is related to your exercise, blood pressure, etc. All you have to do is pull out the knife while you're going downstairs. ”

Su Cheng said: "The most powerful thing in this case is your ex-girlfriend, no, it's your girlfriend." Ruthless enough, you are all ruthless, in order to escape suspicion, one was stabbed and the other was imprisoned. I've long been sure you're in cahoots with your girlfriend. But I need proof. The proof is in your daily life. ”

Su Cheng: "You want to implement this plan, there are several difficulties, the first difficulty, the fake stab can't be seen by people, your online records have already explained, I won't say more." Actually, your girlfriend plays the magic video more times than you, you must have rehearsed it many times, and you also blocked other people's view with your body at that time. The second difficulty is that this knife must be stabbed, but the steak knife will really kill people, and this knife must be ruthless enough and not die. After all, it is a steak knife, and the impact of stabbing yourself is not enough, so you can't stab the ribs, and if you stab the ribs, the blade may not be able to pierce it, and there may be a slippery knife, which not only hurts your own life, but also is completely different from the wound that the lawyer sees. The criminal police team investigated your and your girlfriend's background, and there is no medical background, how did you do it?"

Su Cheng: "From your girlfriend's communication records, we know that she and her cousin, who is an intern doctor in the hospital, have been in frequent communication in the past two months. I haven't looked for her cousin yet, and I guess her cousin will tell me that your girlfriend asked about the relevant knowledge, and the left breast is the piece of meat, and only one point is the best, the shoulder down to the ribs. That position is mostly muscles, and the damage with a toothed steak knife is still quite large. But your girlfriend is so ruthless, and you can tell how ruthless she is from the fact that she is willing to go to jail for more than three years to cover up her crimes. ”

Su Cheng said: "The highlight is the most critical point, I don't think you have the ability to arrange this case, it's not that I look down on you, it's true, you have no criminal record, and you don't have relatives who have felonies, how did you think of this criminal method?"

Xiao A looked at Su Cheng and could already hear his panting,

Su Cheng said: "The Nile murder case in the autobiography of the big pineapple (the case solved by Polo in Agatha Christie's book, which also solved the famous murder case of the Oriental Train. ）。 The big pineapple has very few fans in China, and although the autobiography has a translation, the sales are very low. There are many differences between the Nile murder case and this case, but the subject is the same: Accomplice A attacked Accomplice B, pretending that he was seriously injured and could not commit the crime, and then Accomplice B committed the crime and then harmed himself. ”

Su Cheng picked up the desktop computer and flipped through it: "Your girlfriend has a record of borrowing the autobiography of the big pineapple in the library, and the Nile murder case is among them, and by this time, I am 100% sure who the murderer is." ”

Su Cheng put down the computer: "I know you are going to die and struggle, ask, do you have evidence? Actually, I sympathize with you, I am willing to give you a chance to turn yourself in." Why do I sympathize with you? Because I know far more than you think, I know that although you don't like the dead in your heart, you are also touched by the true feelings of the deceased, and the deceased is indeed quite rich, which can greatly improve your quality of life in the future. It's a pity that you have a very ruthless girlfriend. Su Cheng glanced at his bald head, if you say the subordinates and the leaders wrong, then it will be embarrassing next. When Su Cheng was sure of his confession and took down the suspect, he didn't bother to collect evidence.

The bald head smiled confidently.

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

Xiao A laughed helplessly at himself and said, "That's right, I killed the person." “

Xiao A is a very unassertive boy, he feels that it is not good to be intimate with the deceased at first, but he feels that this life is good. But I can't get around my girlfriend. My girlfriend had a cat and liked it very much, and when the two were in love, Xiao A went to his girlfriend to tease the cat and was scratched by the cat. Little A went to get a rabies vaccine and went downstairs to see that the cat had fallen to its death downstairs. The girlfriend said that the cat jumped to the window by itself, thinking that it could fly. At that time, Xiao A didn't go to his heart.

After the relationship between Xiao A and the deceased was learned by his girlfriend, his girlfriend asked him, do you know how XX (kitten's name) died? Xiao A said he didn't know, and his girlfriend said that because it hurt my most beloved person, I threw it out. You're going to choose her, and I'm not going to die myself.

Xiao A was uneasy, and two days later, his girlfriend looked for Xiao A, and then told Xiao A that he had a way to make Xiao A very rich, and he didn't have to be angry with the old woman. It is usually difficult for Xiao A to say no to others because of his surname, otherwise he would not be seduced by the deceased. In addition, his girlfriend has flowed twice for himself and is very good to himself, he has some words that he can't say, and he doesn't dare to say that he thinks it's better to break up.

At first, Xiao A refused, but his girlfriend has been working hard to perfect the details, and bought a magic knife with a handle close to a steak knife in the magic shop. As long as Xiao A puts away a steak knife in advance, and after being pulled away by the ambulance, hides the magic knife, everything is seamless.

The lawyer and the nanny deliberately did not rescue Xiao A, resulting in Xiao A not handling the magic knife in the first place. When Little A's mother arrives in the first aid, Little A quietly asks her mother to take away the magic knife that she folded and put in her pants pocket. Xiao A can have this surname and is naturally inseparable from his mother, and his mother will certainly do it. At that time, his mother did not know what the situation was, so she temporarily buried the knife in the soil of the flower pot at home, and a few days later visited Xiao A and threw the knife into the Qinghu Lake near her home. These are only known after the fact.

Xiao A was finally moved by his girlfriend to get the deceased's property, and he didn't have to cooperate with the deceased to be a little white face. Afterwards, he could go abroad and become a chic rich man, so why not do it? He thought, this is good, that is not bad.

After Xiao A explained, the bald head said: "There is a question I want to know, did you hesitate when you killed the person?"

Xiao A nodded: "I hesitated, but thinking that XX (girlfriend) has done something that must go to jail, I have no way back, if I don't kill her, XX explains to the police that I conspired with her, then XX (the deceased) can't forgive me." I'm going to lose everything. So there was a voice in my heart at that time, I had to kill her, I had to kill her......"

The bald head said: "In your heart, you still prefer to choose the rich to marry the deceased rather than the poor to marry your girlfriend, right?"

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

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

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

The bald head smiled and asked, "Didn't you expect that with your girlfriend's surname, she would be in complete control of you when she was released from prison? According to my speculation, she must have evidence of your conspiracy to commit crimes." You like women with strong control ability because you lack assertiveness, and such a woman can bring you a sense of security......" and because of Xiao A's surname, he also gave up resistance when Su Cheng basically said that he was right.

Little A: "Can you give me some self-esteem?"
