Yu Hua's belongings were placed on the table, and the people in the physical evidence team turned on the ultraviolet rays, and there was an envelope in Yu Hua's handbag, the envelope was empty, but under the ultraviolet rays, the front of the envelope was displayed, and Yu Hua was asked to go to the seventh floor of the teaching building at 11:40 that night. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

It can be guessed that someone wants to blackmail the flowers...... Chemistry teacher's gloves, special keys...... In fact, the chemistry teacher went to the apartment where the flowers were too much, left some things, and asked Yu Hua to take the envelope to the bathroom on the second floor of the party to find the answer. The font is written with a pencil and ruler pressed, and it is impossible to check the handwriting.

Strange, since you want to kill Yu Hua, since you can control Yu Hua, why do you want Yu Hua to go to the party? Why don't you let Yu Hua go directly to the teaching building? Su Cheng thinks that the murderer is a chemistry teacher, but he doesn't think that the chemistry teacher will add to the snake, there must be a reason that he doesn't know.

This puzzle is solved, but there is one more puzzle, but the ultimate puzzle is: how did the chemistry teacher kill Yu Hua? Use the handle of Yu Hua to blackmail Yu Hua to jump off the building? No, this is impossible, Yu Hua's character will not commit suicide. And if this handle is so powerful, then it's good to be blackmailed directly, why bother to meet and go to a party?

Su Cheng played with the pen in his hand, thinking, and suddenly said: "Bai Xue, I want the transcripts of the people around the chemistry teacher, the students, neighbors, colleagues, and the opinions of the chemistry teacher himself, and the more special big and small things that happened." ”

"Yes, advisor, have you found a breakthrough?"

Su Cheng shook his head: "I don't know, according to logic, a person's logic is divided into behavioral logic and spiritual logic, and now I can't explain the behavioral logic, so I can only see if the spiritual logic can break through." I was very bold enough to make some guesses, but it took a lot of evidence to confirm my suspicions. But ......"

"But?"

"But if I'm right...... Let's get busy first. ”

......

Interrogation room.

Su Cheng and Zoro sat down, with the chemistry teacher in front of them.

Su Cheng and Zuo Luo glanced at each other, Zuo Luo gestured, and Su Cheng opened the file in front of him: "Teacher Shangguan, hello, I myself respect teachers very much, especially teachers like you should be respected." But that's how the law fucks up, we take people's money and eliminate disasters for people......"

Zoro: "Can you use a good idiom?"

"That's what it means, you just understand. Su Cheng turned the first page and said: "We basically know the process, with the help of our technicians, we learned that Du Yiyi received an anonymous message, which was sent to Du Yiyi by an Internet café, and the above is a photo of Du Yiyi's abortion medical record copy." There is also a sentence that asks Du Yiyi to leave Huashuai. ”

Su Cheng said: "Du Yiyi herself is very inferior, ugly duckling, her parents have very high expectations for her, coupled with the cancellation of the title of top chemical student, academic decline, scholarships and grants have been cancelled, in fact, she will not commit suicide, after all, Hua Shuai is rich and handsome." However, according to the regulations of international high schools, she and Hua Shuai will be expelled, and after Hua Shuai is expelled, she will not be able to study in famous foreign universities, nor will it be difficult to get involved in the field of Fahrenheit's international trade, which will be a fatal blow to Hua Shuai's future. Under this pressure, she chose to commit suicide because of her dedication to love. ”

Su Cheng said: "Before committing suicide, she found you, and in order to thank you for your cultivation, she said sorry to you, probably so." But you didn't read Du Yiyi's will to die, after all, she has a rich boyfriend. It finally happened, you were very angry, the police were investigating, and you, as Du Yiyi's mentor, knew about the copy of the abortion, so you suspected that Yu Hua did it. ”

Then you sneak into Yu Hua's apartment, and take advantage of her weekly swimming time without her phone, and you see a photocopy of the photo on her phone. And so a plan of revenge arises in your mind. Su Cheng said: "First of all, you have to leave some things, such as empty envelopes, letters, or others, I guess you turned the copy into the screensaver of Yu Hua's mobile phone, Yu Hua panicked when she saw it, if this matter was announced, she would not be able to stay in high school." ”

According to the prompt text message or other information left on the mobile phone, Yu Hua took the empty envelope to the party, and when she arrived at the bathroom on the second floor of the party, Yu Hua turned on all the lights and saw the words left on the envelope. So Yu Hua went to the teaching building. Su Cheng said: "There is a troublesome place here, there are no scars on Yu Hua's body, and there are no fights or bruises, how can you, a fifty-year-old middle-aged man, throw her downstairs?"

Su Cheng said: "The logic of behavior doesn't make sense, so let's talk about it from the spiritual logic." You and Yu Hua met, on the seventh floor of the teaching building. Of course, Yu Hua asked what you wanted, you didn't want money, and you said that you wanted Yu Hua to experience the fear that Du Yiyi experienced. You asked Yu Hua to stand on the guardrail and feel the pain in Du Yi's heart when he jumped down one by one. In this way, many accidents can be explained, why it was 11:40, because that was the time of Du Yiyi's death. Why a week later? Because that's the first seven days of Du Yiyi. I wonder even more in my heart why you want revenge. ”

Su Cheng said: "After investigation, we learned about several situations, the first case, you are Du Yiyi's tutor in junior high school. In the second case, Du Yiyi's mother is your college classmate, and you fell into the water in Qinghu in college, and it was Du Yiyi's mother who sacrificed her life to save you, which is also one of the reasons why you became a teacher in Du Yiyi's family. In the third case, you and Du Yiyi's mother are lovers, but after graduation, you studied abroad, and she went to a state-owned enterprise and was eventually laid off. In the fourth case, Du Yiyi and his father only knew that you and his mother were classmates, and the reason why Du Yiyi was able to enter the international high school was because you went through the back door during the interview and made him a top chemistry student. ”

At this point, the chemistry teacher retorted: "No, it's no exaggeration to say that she is the most talented student I have ever met in the past ten years." ”

Su Cheng nodded: "We still thought that you would be Du Yisheng's father, of course not." The heart of love, the feeling of guilt, the former first love lost hope in life, and you chose revenge. Yu Hua's scheming must not be compared with you, Yu Hua really thought that you were so pure, and Yu Hua felt a little guilty about Du Yiyi's death, so he stood on the guardrail and held the cross, I guess you should let the religious Yu Hua repent...... Yu Hua was holding the cross in his palm when he died. But Yu Hua didn't expect that you gave her a ride. ”

Shangguan Chemistry teacher was very calm: "It's a pity that you are so imaginative and don't write novels." ”

Su Cheng turned a new page and said: "You may not know, you are not the only one who wants to find Yu Hua to settle accounts, a couple saw Yu Hua go to the teaching building that day, so they followed Yu Hua upstairs and wanted to teach Yu Hua a lesson." Unexpectedly, I saw you kill someone. It's not easy to pry open a couple's mouth, because they also hate flowers. But...... Do you know that there is a thing called a transaction? The sister of the couple man and his boyfriend use radiation to slowly kill Yu Hua, which is an attempted murder. The prosecutor was very despicable, so he made a small deal, and the prosecutor would intercede for the sister of the couple man in exchange for the couple man telling him what he saw. ”

The chemistry teacher said indifferently: "This seems to be a false accusation, you have no way to close the case, so you can only buy witnesses to frame me." ”

Su Cheng: "I'm kidding, there's no deal, and the couple doesn't talk about it." However, the couple girl was waiting below, and after finding that Yu Hua fell downstairs, she naturally looked up and saw you. Although you are very old, but you are not a professional criminal, you still can't help but stick your head out and take a look. The technical department found a fiber from the Yuhua apartment, which is the glove fiber you hidden. ”

The chemistry teacher looked at Su Cheng and thought for a while, and said, "Okay, I admit that I did want to blackmail Yu Hua and let her feel the grief and unwillingness of Du Yiyi before his death, but I didn't push her, it was she who fell by mistake." ”

Su Cheng said: "Actually, what I said earlier is still a joke, you have the right to retract what you said." ”

The chemistry teacher shook his head: "I know you can confirm a lot of things, with my knowledge, I know that you must have investigated the keyhole of the apartment, with the most professional skills of the police, I believe that what you found will match the material of my private key." It's not that the police don't have skills, but they won't use it in ordinary cases, and when I knew that you were the Z department, I knew that this lie couldn't be fulfilled. ”

The chemistry teacher said: "I didn't intentionally kill someone, it was just an accident, and the accident caused the death of others. You police have no evidence that I killed Yu Hua. In fact, Yu Hua did accidentally stumble. Afterwards, I was nervous, so I went back to the lab and secretly adjusted the time while my students were concentrating on theory. ”

Su Cheng frowned, this is what Su Cheng thought of when he guessed the chemistry teacher's modus operandi. That's right, there is no way to prove that the chemistry teacher pushed Yu Hua, and even Li Shuwen's younger brother probably didn't see this action. Logically speaking, the corridor is straight, and Li Shuwen's younger brother showed his head and saw the two, so he would not show his head all the time, but shrank his head to eavesdrop. Can you convince the judge? It's difficult, no, it's unlikely. The police were obliged to provide evidence that the chemistry teacher had pushed Yu Hua, but the police had no way to provide evidence in this regard.

One of the reasons why Su Cheng likes detectives is also because of this, it is enough for detectives to find the truth, and the police need to confirm the truth. In some cases, such as Conan, as long as the offender denies it, or is not coaxed, or even if he is coaxed, he can deny it, rather than cooperating with the author's thinking, those cases cannot be convicted. In some cases, fishing can only be used without evidence, but can the murderer who can plan the perfect murder fall for this pediatric trick?

Zuo Luo said: "You are a teacher, and it can be said that you are full of peach and plum all over the world, and you have both ability and political integrity...... Do you think like a normal person?"

Su Cheng retorted: "I don't support this, I can do my best to convict you, but I won't restrain and oppress you with high standards of morality." We know in our hearts whether you killed or not, but this is the only way we can do this case, we did our best, and I think I am worthy of my salary. However, death by negligence, if I remember correctly, should be three to seven years. Have you ever thought that in three to seven years, you could have cultivated a lot of talents? ”

The chemistry teacher replied, "I never thought that too many flowers would die, so I didn't think about it that much." ”

Su Cheng smiled and stretched out his thumb: "You are a cow, amazing, admire." ”

Zuo Luo looked at Su Cheng, Su Cheng shook his head, there was no trick, Zuo Luo thought for a while, and waved: "Take him down." ”

The door closed, and the interrogation room was Su Cheng and Zuo Luo, Su Cheng asked, "What tricks do you have?"

Zoro said: "Actually, we can't deny that the teacher has no possibility of killing Yuhua...... What tricks, search, see if you can find some clues, it really can't work, you can only send it for inspection and close the case. ”

"Didn't you search it?"

"Last time we were looking for something, this time we're looking for emotions. ”

......

Re-search, this time not looking for physical evidence, looking for emotion, emotion has to look at the photo first.

The chemistry teacher likes real photos, and there are a lot of photos, there are 40 albums, about 4,000 photos.

The seventh group looked at the photos at the chemistry teacher's house, Su Cheng hated this kind of tedious work the most, asked the chemistry teacher's wife for a bag of black tea, and brewed it himself, ignoring that others did not welcome him. The chemistry teacher has a pair of dragon and phoenix fetal daughters, the son is very strong, is a doctoral student in a famous foreign university, and is currently working as an engineer in the world's top 50 companies, the daughter is very ordinary, after graduating from college, she married a naughty student of the teacher, well-off level, and worry-free life.

The chemistry teacher was originally a chemistry teacher in a key high school, and the teaching level was very high, and he was poached by the international high school in his thirties.

Song Kai said: "The strange thing is that the students of key high schools do not take photos with their teachers anymore, but many graduates of international high schools take photos with their teachers. ”

Su Chengshun took the album in his hand, half-lay on the sofa and looked at it, and said: "What key high schools want is grades, and what they teach is the content of the exam. International high schools teach students according to their aptitude and teach talents. Moreover, international high schools have a classification of top students, and small groups have a greater sense of belonging, and most of those who can be listed as top students have certain abilities in related fields after graduation. Key high school graduates are in college after graduation, and even if they choose a chemistry major, it is more important for them to be a tutor than a high school teacher. ”

Zuo Luo quietly flipped through the photo album, and he could read the pride of the teacher and the character of protecting the calf from the album. But it's not all about the merits, the teacher treats the top chemistry students like his own children, but he is very perfunctory to ordinary students, he thinks that ordinary students can't achieve success in the field of chemistry, they just need grades.

Zuo Luo picked up the corner of his eyes, saw Su Cheng put something in his pocket, and then pay attention, Su Cheng looked at the album casually, but his mind was concentrated, he carefully read a photo album, and then selected a photo album, as if he was looking for something. Zuo Luomo was silent, and he observed silently for more than half an hour, and found that Su Cheng looked at the date of the album after rummaging through the fourth album, and leisurely drank tea again.
