This action is big, the alarm sounds, all the residents of several buildings near the single apartment are evacuated, the special team enters, and the items are sent to the laboratory, after analysis, this thing is called XXXX, which is used in industrial and medical use, and the radiation ability is relatively weak, and the activity is relatively poor...... As the saying goes, the range of radiation is small. Pen, Fun, and Pavilion www.biquge.info and has relatively low damage. Unless it is a relatively long period of close contact, it will cause irreversible radiation damage to people.

All personnel who have entered the room have been admitted to the hospital for observation, and Su Cheng and Zoro are in the same ward.

Su Cheng: "I suddenly want to overturn the inference that the chemistry teacher is the murderer. ”

Zuo Luo said: "How can a teacher who is proficient in chemistry use physical methods to kill people, right?"

A member of the physical evidence team in the same room reminded: "Two, chemistry is a second-level discipline of physics, but it is a relatively special discipline. To be precise, the nucleus belongs to energy. ”

While talking, Bai Xue and the others all came, and asked with concern, "Are you okay?"

The doctor came in: "After many tests, your sperm is normal, unaffected, and you can be discharged in the afternoon." ”

The atmosphere was awkward for a while, and Su Cheng raised his left hand: "The iron palm floats on the water." The process of inspection was explained.

Zoro hurriedly changed the subject: "What is the progress of the case?"

Everyone sat down, Fang Ling said: "This thing is called XXXX, it is a thing from the A large boiler research department, the last inspection was four days ago, and he is still there." ”

Su Cheng said: "The thief was caught?"

Fang Ling nodded: "His name is Huang Ye, he is a sophomore, and he is a work-study student in the research department. ”

"What does Huang Ye have to do with Yu Hua?"

Fang Ling asked: "Yu Hua became the school flower in the first year of high school, when there was a strong competitor in the second year of high school, named Li Shuwen, it is rumored that Yu Hua used some means to force Li Shuwen to withdraw from the competition, and handed over the throne of the queen of socialization, and transferred to an ordinary high school. This Huang Ye is Li Shuwen's boyfriend. ”

Zuo Luo patted his forehead: "Su Cheng, you are a scourge, to accompany you to drill the tip of the horns is to throw away the real murderer." ”

Fang Ling nodded: "Huang Ye has confessed, someone sent an indecent video of Huang Ye and Li Shuwen to Li Shuwen's mobile phone, forcing Huang Ye to transfer and leave the international high school. However, they have not been sure whether Yu Hua is the mastermind, seven days ago, that is, on the third day of Du Yiyi's suicide, Li Shuwen and Yu Hua met by chance at a classmate's birthday party, Yu Hua found out that he apologized to her, and told her that the video had been deleted to rest assured. Li Shuwen and Huang Ye knew that it was Yu Hua who did it, so they plotted revenge. ”

Su Cheng said: "Wait, since they all thought of killing people with radiation, why should they do anything to flowers?"

Fang Ling said: "This case is full of surprises, Li Shuwen's younger brother is a first-year student in an international high school, twenty minutes before the incident, Brother Li went back to the teaching building to get notes, and at the same time he was the first batch of people to find Yu Hua's body, he was among the four onlookers, he also went up to check Yu Hua's situation, and asked another classmate to call the emergency number." ”

Song Kai asked proudly: "Consultant, head, are you surprised, are you surprised?" ”

Zuo Luo asked rhetorically: "Li Shuwen's younger brother has been recruited?"

"No, he said that he went to the teaching building to get his notes, his classroom was on the fifth floor, and after taking the notes, he went downstairs, heard the voice, and looked over and saw Yu Hualuo Building. He denied that he had ever seen Yu Hua. Ask him why he didn't take the initiative to explain to the police that he was in the school building at the time. Brother Li replied that he was very scared when he found out that the deceased was Yu Hua, because he just knew about his sister and Yu Hua, and he hated Yu Hua very much, and Yu Hua died, and he was afraid that the police would suspect him. ”

Zoro said, "What do you think?"

Song Kai said: "We think that Yu Hua is likely to go back to the teaching building to get his own things, Brother Li found out and followed, the two sides had an argument outside the seventh floor, Brother Li practiced judo all the year round, we suspected that Yu Hua was thrown out, when Brother Li stepped forward to give first aid, the clothes that Yu Hua was caught were sorted out, so that we did not find any flaws." ”

Su Cheng nodded: "There is some truth, but Li Shuwen's younger brother should be facing the police for the first time, what do you think of the interrogation process?"

Fang Ling shook his head: "It seems that what he said is true, but he is very excited and nervous." ”

Zuo Luo sighed deeply: "This case is getting more and more interesting. ”

Su Cheng raised his hand: "Stop...... There are more and more clues, more and more suspects, and the pool is getting deeper and deeper, and I don't like that. I'm going to use my method to analyze the case once. ”

Su Cheng said: "First of all, Li Shuwen, who competes with Yu Hua for the school flower, Li Shuwen's boyfriend got XX dangerous goods, normally speaking, it is only a matter of time before Yu Hua is killed, so Li Shuwen and her boyfriend Huang Ye will not be murderers logically." ”

Su Cheng said again: "Li Shuwen's younger brother, a person who practices martial arts, is very big, and he and Yu Hua were in the teaching building at that time, and they have the ability to kill. Li Shuwen's younger brother is a suspect, but judging from the interrogation, he does not look like a murderer. ”

Su Cheng said again: "Chemistry teacher, he has the motive to kill Yu Hua, and he can also make the time to kill Yu Hua. But I don't think the physical strength of the chemistry teacher is very good, and I don't think a scholar in his fifties can throw Yu Hua out of the teaching building, and Yu Hua did not resist during this period. "If there is a physical altercation, an autopsy can be found. Yu Hua's body did not show any signs of physical conflict.

Zoro asked, "You mean the chemistry teacher can rule out suspicions?"

Su Cheng said: "I suggest that Li Shuwen's younger brother be arraigned, if his suspicion can be ruled out, then the murderer can only be a chemistry teacher." ”

Zuo Luo was dissatisfied: "That's how the detective handled the case? Now it's obvious that Li Shuwen's younger brother is the most suspicious, what is your basis?"

Su Cheng replied: "Li Shuwen's younger brother is only sixteen years old, if he kills someone, he will definitely have to urinate in the first trial, unless he is an antisocial personality." I don't think the chemistry teacher has the physical strength to throw flowers out of the school building, but I always feel that he has the ability to do it. I'm particularly concerned about a suspicious place, Yu Hua is a social queen, she went to the party on the night of her death and didn't update her blog, and Yu Hua is not a resident student, she ended the party early and went to the teaching building, wouldn't this behavior be too weird?"

Zuo Luo said: "Then since this is the case, the soldiers are divided into two ways, Bai Xue, you follow Su Cheng." ”

……

Zuo Luo interrogated Li Shuwen's younger brother: "Xiao Li, there is a witness to prove that you went to the teaching building after buying a mask. ”

Li Shuwen's younger brother said: "Okay, I'll be honest, I just want to beat her." ”

Li Shuwen's younger brother was accompanied by a legal adviser dispatched by the police station because he was a minor, and the legal adviser reminded: "What you think subjectively and objectively does not happen, you have to make it clear." ”

Li Shuwen's younger brother raised his head, and Mu Ran looked at Zuo Luo: "It didn't happen." I wanted to vent my anger for my sister. ”

The pen in Zuo Luo's hand slowly knocked on the table, came back, knocked again, looked at Li Shuwen's younger brother scrutinically, and asked after a long time: "What do you think of flowers?"

"Opinion?"

"Yes, looks, people, etc. ”

"I ...... I do not know. ”

Zuo Luo said: "Xiao Li, do you know how much trouble you are in now?"

Li Shuwen's younger brother said: "I didn't kill anyone. ”

This sentence is interesting, and the implicit meaning of this sentence is that Li Shuwen's younger brother actually knows something, but he doesn't want to say it, and he doesn't want to make it up anymore. Li Shuwen's younger brother has never faced the police, but he has perjured before, indicating that there must be something wrong inside.

Zuo Luo looked at Li Shuwen's younger brother: "Did you see something?"

Li Shuwen's younger brother shook his head: "No, you can arrest me, I didn't kill anyone anyway." ”

Zuo Luo thought about it and said: "I remember that when I was studying in the police academy, there was an exam, there was such a question, there was a swimming coach, because his wife cheated on the two and they were about to divorce, one day the coach rode home, passing by Qinghu, heard someone calling for help, so he went down to the Qinghu embankment, only to see his wife calling for help, and her lover struggling in the water. ”

Li Shuwen's younger brother asked: "As soon as the coach left, ask the coach if he is guilty?"

"No, the coach jumped into the water. ”

Li Shuwen's younger brother ridiculed: "It turned out to be a gentleman who repays grievances with virtue, there are not many such good people, and he should belong to the national treasure-level figure." ”

Zoro said: "You guessed wrong, the coach did not save people, but swam near his wife's lover, admiring that his lover was drowned in the end." ”

"Huh?"

Zoro said: "This question is not difficult, the answer is that the coach is not guilty, because he is not a legal obligation to save people, the police, if the fire does not save when he sees death, it is a crime." Secondly, it was not the coach who caused the lover to fall into the water, and he had no obligation to rescue. But this is a real case that happened in Qinghu, after the coach's wife committed suicide, the coach also lived in guilt, left City A, and wrote a letter of apology to her lover's family before leaving. ”

"What do you want to say?"

"Yu Hua did use a conspiracy to cause your sister to lose something, but first of all, your sister was at fault, after all, she was caught doing something. Dare to act, nothing. Secondly, Yu Hua is not a heinous person, she is a seventeen-year-old girl, she died, and you watched her die indifferently. Do you feel like that coach, you could have saved her? ”

Li Shuwen's younger brother retorted: "How is it possible, it was a matter of a moment......"

The legal counsel immediately said: "Team Zuo, you are inducing a confession, and my client can not be responsible for this sentence." ”

Zuo Luo nodded and looked at Li Shuwen's younger brother: "Can you tell me about the situation at that time?"

Li Shuwen's younger brother shook his head: "I don't have anything to say, I don't know anything." ”

If Yu Hua committed suicide or had an accident, Li Shuwen's younger brother would not be able to carry it, it is very likely that Li Shuwen's younger brother knew who the murderer was, and the murderer had something to do with him.

Zoro suddenly asked, "Are you a top chemistry student recognized by an international high school?"

"Yes......" Li Shuwen's younger brother asked forcefully, "What?"

Zuo Luo took a deep breath and said: "I think I know the process, if I am not wrong, the process is like this, you heard about your sister being framed, and then at about eleven and a half that night, you saw Yu Hua, Yu Hua walked towards the teaching building, you followed, maybe you want to reason with her, maybe you want to beat her, but you found that Yu Hua was meeting with someone, and this person showed considerable hostility towards Hua, so you listened and watched, and suddenly Yu Hua died." ”

Li Shuwen's younger brother forced himself to calm down: "Officer, your ability to make up stories is really amazing." ”

Zoro said: "I can track down very detailed things. Let me remind you that it is a crime to commit perjury, and if you have a criminal record, you will not be able to go to many countries. ”

The legal counsel whispered in the ear of Li Shuwen's brother: "He has no interest in your perjury, but if you don't say anything, he will take your charges seriously." ”

Li Shuwen's younger brother thought for a while: "That's right, I saw Yu Hua walking towards the teaching building, so I wanted to teach her a lesson, I bought a mask from the commissary, and I didn't want to be identified by her." After a few minutes of delay, I saw Yu Hua in the corridor on the seventh floor, so I went up, and when I got to the seventh floor, I saw her fall down......"

"How did you fall?"

Li Shuwen's younger brother made a move: "Yuyue? I forgot...... I had witnesses, my girlfriend was there, and she kept telling me not to do stupid things downstairs before I remembered to buy a mask. She watched downstairs, she didn't see Yu Hua in the corridor, but she saw me at the staircase, she could prove that when Yu Hua fell downstairs, I was at the staircase, and Yu Hua fell at the other staircase, at least 18 meters away. ”

Zoro asked, "Why didn't you say it before?"

Li Shuwen's younger brother said: "I don't want to cause trouble. ”

……

Su Cheng: "Suppose the chemistry teacher kills someone, and he adjusts the time to falsify alibi, he needs precise time." And why didn't Yu Hua take photos at the party and upload them? Because the reason why Yu Hua went to the party was not to attend the party. She probably went to pick up something and was asked to go to the school building. The chemistry teacher didn't go to the party, so how could he ask her out? ”

Bai Xue said: "So we have to solve this puzzle first, right?"

Su Cheng said: "This puzzle is not very important, I just wonder how to kill people...... But it's better to go to the party scene first, it's strange, a professional chemistry expert, why doesn't there be a little chemical factor in the murder trace?" The tendency of murder is like this, and the murderer is more accustomed to using his strengths to attack the weaknesses of his target.

Bai Xue said: "According to the transcript, the party owner said that Yu Hua left in a hurry after borrowing the bathroom on the second floor of the villa. The party owner said that the second floor was a private quarter, and it was not open during the party, and his parents were on the second floor. But because there were people in the three bathrooms on the first floor, Yu Hua was in a hurry, so the party owner took her to the second floor. On the second floor, there are master bedrooms, two second bedrooms, two guest rooms, and there are no separate toilets for the study, guest rooms and a second bedroom, and there is a shared toilet on the second floor. ”

Su Cheng said: "Give me the phone number of the party host, I'll contact, let's drive." ”

……

Su Cheng entered the bathroom on the second floor of the villa, a very ordinary toilet, a bidet toilet, a sink, and a glass-separated shower room.

The host of the party introduced: "I am from Linyuan County, there are many relatives, my father attaches great importance to feelings, and when relatives come to City A, they will let them stay for one night as much as possible, and do their best to be the landlord." The bathroom is what they use. ”

Su Cheng asked, "What about your mother's attitude?"

The party host smiled and replied, "Of course my mom welcomes it." ”

Su Cheng also smiled: "Since you are welcome, why do you need to install a special ultraviolet lamp for bacterial disinfection?"

The party host was upset: "What do you mean?

However, the guests did not know that there was a UV lamp in the lamp that was turned on together. Su Cheng turned on the light, the three lights were on together, and he couldn't see the ultraviolet rays, and he was pressing the other two switches, turning off the two lights, and the bathroom was full of purple. Su Cheng said: "Bai Xue, let's go." ”

Ultraviolet lamps are currently commonly used for household disinfection, and it is best not to be in them. The good thing is that as long as the UV light is turned off, you can enter the room directly without any side effects. Ultraviolet lamps have special effects on a variety of viruses and bacteria, and have strong sterilization ability.
