Special Case Investigation Team

Chapter 7 Drug Poisoning Case (6)

After Cheng Jin and the others finished seeing Zhao Zi, they went to see Si Buming. Han Bin also knew Professor Si, but he was not as familiar with Zhao Zi.
 
After they came to Si Buming's office and explained their intentions, Si Buming received them warmly. Si Buming is different from Zhao Zi. Zhao Zi is an academic and devotes himself to learning, while Si Buming is good at managing interpersonal relationships. He is now the vice president, and it is said that he is very likely to take over after the dean retires.
 
Si Buming's face was very heavy, "Song Qiyuan was a good student who was friendly and excellent in studies. I can't figure out how this kind of thing happened to him. Why him?"
 
"Professor, was Song Qiyuan's stomach medicine also prescribed at Huiren Hospital?"
 
"I don't know about this, but it should be."
 
Cheng Jin asked some more questions, and he found that Si Buming often glanced at his cell phone when answering the questions. He remembered one thing: when they came over just now, Si Buming was on the phone, but he hung up immediately after seeing them.
 
Cheng Jin casually glanced at You Duo next to him and then said in surprise, "You Duo, what's wrong with you? Why do you look so bad?"
 
You Duo's face was pale, and he was on the verge of falling. Han Bin rushed to help him. He slid onto the ground like he was in weightlessness, causing Han Bin to stagger.
 
Cheng Jin hurriedly said to Si Buming, "Professor, please help me find out what's wrong with him."
 
SI Buming was also startled, so he hurried over and checked quickly: "This symptom... he should be sent to the emergency room as soon as possible!" Si Buming couldn't see the symptoms for a moment, but he saw that the whites of You Duo's eyes were turning up, and he was about to foam at the mouth. He looked out of breath; he was also anxious, and he immediately wanted to find a colleague for help, but You Duo clung to his sleeve like a life-saving straw.
 
Han Bin also urged: "Professor, where is the infirmary? We have to send him there quickly."
 
"Yes, come with me!"
 
Si Buming and Han Bin hurried to the infirmary, carrying You Duo.
 
Cheng Jin hurriedly walked to Si Buming's desk, turned on his mobile phone, and quickly recorded the recent contacts. After thinking about it, he simply took off his mobile phone card and copied a copy of the address book onto his mobile phone.
 
Then he looked around and saw a magazine on the table, which should have been flipped by Si Buming not long ago. He opened it casually and found that a page was folded, so he looked carefully. There is an article on this page, and the author is Song Qiyuan. He took a picture of the cover of the magazine with his mobile phone, and when he heard someone approaching outside, fearing that Si Buming was back, he hurriedly restored everything and then walked towards the door of the office.
 
However, when he walked near the door, he found that it was a strange teacher.
 
He smiled and said, "Teacher, do you know where the infirmary is? Professor Si took my colleagues there just now, and I want to find them."
 
"Go downstairs and turn left, and you can see it after a short walk."
 
"Okay, teacher, what's your surname? Professor Si left in a hurry, and the office is unlocked. Can you take care of it?"
 
"My surname is Wang. You can go. I'll watch from the opposite side." The teacher immediately agreed.
 
"Thank you very much! Then I'm leaving. Goodbye, Mr. Wang." Cheng Jin ran away.
 
After he ran to the infirmary, he saw You Duo lying peacefully on the bed. He asked out of breath, "Professor Si, is he alright? What happened to him just now?"
 
Si Buming hesitated for a while, but still said, "It's a bit like epilepsy* symptoms; it's best to go to the hospital for a proper examination."
(kiwii: also called seizure disorder.)
 
Cheng Jin was very surprised: "This...how could..."
 
Si Buming patted him on the shoulder: "It's still uncertain; the specific situation will only be known after a careful examination at the hospital."
 
"Yeah." Cheng Jin still had a grim face and forced a smile: "Professor Si, thank you today; you didn't lock the office in a hurry when you came out. I asked Teacher Wang, who is opposite you, to help take care of the office."
 
"Mr. Wang? The office opposite me belongs to Dean Wang."
 
"Ah? Then I was really rude. I hurried down and didn't ask clearly." Cheng Jin was a little embarrassed.
 
"It's okay; Dean Wang doesn't care about these things. Then I'll go back too. If my help is needed for anything, you can come to me immediately."
 
"Okay, thank you, Professor Si."
 
After sending Si Buming away, Cheng Jin walked back to the infirmary bed, looked at You Duo, who was motionless on the bed, and asked Han Bin beside him, "What's wrong with him?"
 
Han Bin said, "Just now the doctor gave him a sedative injection."
 
"..." Cheng Jin was silent for two seconds, "Then let him sleep."
 
On the other side of the dormitory, Yang Simi and the others have already finished their work.
 
Xiao An was very excited: "Mr. Yang, you are so amazing and know a lot; have you really studied psychology?"
 
Yang Simi returned to his expressionless face: "Self-study."
 
Bu Huan looked at them helplessly: "Well, the problem now is that we have to report to the bureau immediately and let them arrange a real training session for us. It’s not good to reveal the identities of the psychology teacher and student later.”
 
Xiao An was still pestering Yang Simi to ask this and that; she is not afraid of the expressionless Yang Simi now—as if mistaking a tiger for a big cat.*
(kiwii: it means literally mistaking a big threat for something harmless.)
 
Bu Huan found that no one was paying attention to him, so he could only make a phone call to report the situation to the higher authorities in a low mood.
 
They returned to the car and found that Cheng Jin and the others hadn't come back, so they began to listen to the information returned by the wiretapping equipment they left in the student dormitory.
 
Bu Huan first connected to the bug in the boy's dormitory, and a voice came from there:
 
"A psychologist? Afraid we have psychological trauma? How can we have trauma? The school is definitely worried about whether one of us poisoned Song Qiyuan."
 
"Don't talk nonsense; it's not good to let interested people listen to it."
 
"Tch, so what if you talk about it…”
 
"But it's true, we have had a lot of work lately. There was an accident at Liao Shixin's house a few days ago, and now another accident has happened."
 
"It's different. It's not Liao Shixin's accident; it's his family's accident, but he was already in low spirits, and now his family is like this... I don't know what will happen to him…"
 
After listening for a while, they saw Cheng Jin and the others coming back through the car window, but they only saw two standing people; You Duo was carried by Cheng Jin, they got out of the car quickly, "What's wrong with You Duo?"
 
Cheng Jin roughly explained, and Xiao An tilted her head: "That is to say, You Duo is pretending to be sick? It seems that today we all showed our perfect acting skills!"
 
Cheng Jin smiled and said, "Really? What did you do?"
 
Bu Huan talked about the situation on their side and said, "I reported the situation to the bureau, and Wei Qing said he would come right away."
 
"Yeah." Cheng Jin responded, then looked at Yang Simi with a smile, "Psychologist... After I go back, I want to hear how you acted perfectly."
 
Xiao An said regretfully, "It's a pity that yours was not recorded."
 
Cheng Jin smiled and didn't say that he had a recorder in his pocket, but those were actually nothing to listen to.
 
Wei Qing quickly brought people here, and he looked at them with a frown: "Leave this place to us now; you can go back and take that car." He pointed to another car for them.
 
Bu Huan asked him, "What about the one in our car…" They were bugging the dormitory.
 
"These are not in compliance with the regulations. We will deal with them, and we will also remove the bugs from the student dormitories." Wei Qing said with a straight face.
 
Yang Simi removed the recorded tape from the radio and put it in his pocket. He turned around and got into another car.
(kiwii: lmao, YS is so straightforward and disobedient)

Wei Qing's face turned blue, but he still held back and said nothing.
 
Bu Huan was still driving when they went back. He hoped that someone would take the initiative to drive, but unfortunately, no one was considerate.
 
Yang Simi handed the tape to Cheng Jin.
 
Cheng Jin took it and said with a smile, "It's fine to let Bu Huan do things like take the tape; why are you going?"
 
Bu Huan: "..." He is working as a labourer and a foil today.
 
Yang Simi looked at Cheng Jin innocently: "You said you wanted to listen to what we performed."
 
Cheng Jin smiled, "Yes. Let's go back and listen."
 
A few hours later, You Duo woke up on the bench in the office.
 

When Xiao An saw it, she ran over and asked him, "Are you hungry? You missed lunch, but we packed it for you. Would you like me to warm it up for you?"
 
You Duo looked at his watch; it was already 6 o'clock. "No need; let's have dinner together later." He sighed, "It's the first time I've been sedated." It was also the first time he slept on an office chair for hours under the noses of dozens of people, and he didn't want to sit here alone to eat during working hours.
 
Bu Huan came over: "Boy, there is a first time for everything."
 
"So, is there any progress now? Where's Cheng Jin?" You Duo looked around, but he didn't see Yang Simi.
 
"They went to Liao Shixin's house; we finally have a suspect!" Xiao An answered him.
 
"Liao Shixin?" You Duo was running his brain at high speed, searching for information about this person, "He is Song Qiyuan's classmate, and he is also an intern at Huiren Hospital, but his parents had a car accident two months ago, and he has been busy taking care of his parents; his parents passed away a week ago, and he asked for leave to arrange his parents' funeral. Isn't his suspicion ruled out?"
 
"It's a long story; let Bu Huan explain it to you. I have to check if there is anything useful in the computer of my 'senior brothers'." Xiao An went back to the computer and started working.
 
When she borrowed the computer of a boy from the medical university, she left a Trojan horse virus* on the other computer. After a few hours of swimming in the local area network of the boy's dormitory, the virus infected all the computers, and now the doors of these computers are all wide open to Xiao An.
(kiwii: In computing, a Trojan horse is any malware that misleads users of its true intent by disguising itself as a standard program.)
 
Bu Huan poured a glass of water, sat down, and told You Duo the current development of the case.
 
After they returned from the medical university, they checked Si Buming's call records and found that the person he had contacted the most recently was Song Qiyuan's father. However, it is not suspicious to maintain contact between teachers and student's parents.
 
But something else was unearthed. Didn't Cheng Jin see a paper published by Song Qiyuan in the magazine on Si Buming's desk? Coincidentally, there is a section in this paper about the research of various toxins that contains a lot of data that can only be obtained through a lot of experiments, but Song Qiyuan's name is not listed in the laboratory usage records.
 
Wei Qing asked someone to go to the dormitory to ask his classmates. No one knew about Song Qiyuan doing experiments and writing a thesis. They said that his grades were mediocre—the implication was that they did not believe that he could write that kind of thesis.
 
They said that in their class, Liao Shixin and Hong Fei were known to have the best grades and the most frequent visits to the laboratory. They would stay in the laboratory for a long time, so the professor gave them the key to the laboratory so that they could come in and out freely.
 
After verification, it was Si Buming who gave them the key.
 

Si Buming said that this was a very common thing, and he didn't think it had anything to do with the case, so he didn't tell the police. In addition, he said that he knew about Song Qiyuan's thesis. He said that Song Qiyuan had real talent and learning, but this young man didn't like to be in the limelight and had never gone out to publicise it, so not many people knew about it.
 
Wei Qing asked someone to ask Song Qiyuan's girlfriend, Guo Lei, but like other students, she didn't know about the thesis.
 
They also went to Hong Fei, but they couldn't get in touch yet. He recently went home on leave. Like Song Qiyuan, he also applied to a foreign university and received an admission notice. He will go abroad after a while.
 
They also launched a series of investigations around Liao Shixin.
 

They checked the records of books he borrowed in the last year and found that there are many books on toxin research and many books related to "Song Qiyuan's papers". They also learned from other professors that he had indeed done some research on toxins and had also done many experiments that seemed to have a causal connection with "Song Qiyuan's paper".

At present, there is no clue that Song Qiyuan has read those books or done those experiments.

Regarding Liao Shixin, he is from this city, and his family is a very ordinary family. What is unusual is that two months ago, the taxi his parents were in was involved in a car accident.
 
It was late at night, and the taxi they were travelling in was hit by a giant coil of steel wire about 1.5 metres in diameter that rolled down from the truck. The driver died on the spot. Liao Shixin's parents were seriously injured and spent several days in the intensive care unit of the People's Hospital, but finally died on October 6.
 
Wei Qing once again sent people to question the staff of Huiren Hospital, this time about Liao Shixin. Someone provided a clue: Liao Shixin had appeared in the hospital on October 11 and 13.
