Chapter 526: Controlling Dr. Wu

While the interrogation was going on, in the afternoon, Lu Yongqiang took people to Gong Qingliang's home to conduct an on-site re-examination.

Since four women came the day before the crime, we must be thorough in our search for clues.

Re-investigation is an extremely important means in criminal investigation work, which helps to improve the accuracy and success rate of case detection.

There may be omissions in the initial investigation, the crime scene is complex and diverse, and no matter how high-tech the trace inspection is, it cannot guarantee 100% perfection.

There is a reason why the time point was chosen in the afternoon. Certain traces that have not been noticed before may appear under different conditions such as light and angle.

The most important thing is that the cause of death of the victim Gong Qingliang has been found. Trace inspection needs to be carried out again, such as cups, dishes and other tableware, hoping to determine how the poison was introduced.

Chen Yi is still watching the real-time monitoring of the interrogation. There is no breakthrough yet, no one has revealed any flaws, and there are no inconsistencies in the answers.

Everyone was the same, contacting in advance, going upstairs, meeting, chatting, and making out. Bao Linlin and Cao E also accompanied Gong Qingliang to lunch and lunch.

The interrogation lasted for more than two hours, and all the questions that needed to be asked had been asked. It seemed that no one was prepared to admit that the police needed more clues.

"Detain them all and let them think carefully in the detention room." Chen Yi gave the order.

Judging from the time when Gong Qingliang was poisoned, these four women are extremely suspicious and meet the procedural standards for temporary detention.

When did you ask: "Locked up alone?"

The number of detention rooms is allocated based on the city's population size, public security situation, number of cases and other factors. In principle, each police station must have at least one detention room, and there are more in municipal bureaus. It is not a problem to detain four people individually.

Chen Yi: "No, locked in a room."

Does anyone know that Gong Qingliang is actually a Neptune relationship liar? If only one person knows, then the other party's suspicion of committing the crime is relatively high.

Locked together, maybe something can be learned.

"Okay." When did Xin go to make arrangements?

After learning that they were going to be temporarily locked up, except for Bao Linlin, the other three women were relatively calm, especially Luna, who seemed to be very experienced.

Bao Linlin cried again, this time not for her boyfriend but for herself. It was the first time for a young girl to go to the public security bureau and she was put in the detention room. She was definitely anxious and panicked.

She wanted to call her father, but Shi Xin didn't agree after asking Chen Yi for instructions. She would naturally contact her family when it was time to do so.

The detachment held a meeting.

Chen Yi didn't say anything nonsense, and directly arranged the next investigation task to dig deeper into more information about the four people, including but not limited to mobile phones, computers, homes, private lives, financial status, etc.

Deliberate murder takes time, not only time for psychological struggle, but also time for preparing the conditions for committing the crime.

Look for abnormalities to indirectly determine who is the poisoner.

"Team Chen, it's not easy to talk to the research institute. There may be resistance in leading people to investigate."

At the meeting, Zhuo Yun briefly talked about what happened at the institute before. Scientists are different from ordinary people. Communication is a bit difficult and must be handled carefully.

The country's senior intellectuals are somewhat privileged.

"I'll go, Qin Fei, take two people with me." Chen Yi said.

Qin Fei nodded: "Yes."

Chen Yi: "Others, if you make any major discoveries, please call us immediately. Investigation work will begin immediately. Go ahead and get busy."

"yes!"

Everyone stood up and left the conference room.

Chen Yi was the last to leave, leading people straight to the research institute.

Zhuo Yun said that people at the institute did not know that Fan Zhimei was in love, but what they wanted to investigate was not this matter, but Fan Zhimei's financial situation and the source of the poison.

Two million and six hundred thousand is not a small amount. Just check and find out whether she can earn this amount of money.

If not, then Fan Zhimei has financial problems and has a more sufficient motive to commit the crime.

She took a huge risk to help her future husband get through the crisis, but found out in the end that she had been deceived. It is not surprising that she would do anything in anger.

Detention room.

It was very quiet, with only Bao Linlin's sobs echoing around. The four people were sitting two meters apart from each other and seemed to have no intention of chatting.

"Can you stop crying?"

Ten minutes later, Luna frowned and looked at Bao Linlin, with dissatisfaction in her voice.

Bao Linlin's crying stopped suddenly and she covered her mouth.

She is very obedient, maybe because she is afraid of the people who are also imprisoned. She does not know what crimes they have committed. The unknown is the biggest fear. What if there is a perverted murderer?

After Luna said something, she looked away and continued to lower her head in silence. The detention room became even quieter.

There are people guarding the door and keeping an eye on the surveillance camera. In fact, the police would rather let a few people chat.

As long as we talk about Gong Qingliang, the scene will be exciting and there will be many flaws. It's a pity that no one is the first to speak.

…

Chen Yi arrived at the research institute.

The full name of this institute is Plant Protection of the Academy of Agricultural Sciences. It is mainly engaged in the research and prevention of crop pests, plant breeding and pollination, etc. It is more public welfare and the state provides scientific research funds.

This research institute has been in Yangcheng for sixty years.

Chen Yi has obtained basic information. There are 60 employees, 50 technicians, and as many as 30 people with doctoral degrees. The technicians are also graduate students at last. It can be said that it is a gathering place for highly educated talents.

"Okay, I get it."

Before entering, Chen Yi hung up the call to the provincial department.

The place was special, so he needed to seek advice from the provincial department, such as what to do if he resisted the investigation. The provincial department said that he should try to be more harmonious and avoid any stalemate.

Fifty scientists and thirty Ph.D.s would have a headache even if they were to unite the provinces and departments. There was no need for Chen Yi to offend national talents because of a case.

Since he is highly educated, he should be able to cooperate and not act rogue.

After entering the office and showing his ID, Chen Yi met the director. Both of them were of the same rank.

He was not as polite as expected, and the director's face looked a little dark.

"Captain Chen, didn't you just take someone away? Are you here in person again?"

The director wearing glasses was very young, with a Chinese character face, and looked to be in his forties. He should know Chen Yi, but he didn't give him face.

Fan Zhimei was taken away by the other party's men, and his mood was naturally not much better.

Chen Yi sighed: "Dr. Wu, please take more care of this murder case."

"I know about the murder." Dr. Wu said without a smile, "Did she really do it? Don't make a mistake."

Chen Yidao: "It may not be her, but there is considerable suspicion. We need to conduct further investigation, so..."

Dr. Wu was surprised: "Come to the institute to investigate? What is there to investigate?"

Chen Yi: "Of course we are here for a reason."

Dr. Wu: "What's the reason?"

Chen Yi: "..."

This person likes to ask rhetorical questions.

In the process of communication between people, rhetorical questions can most affect the other person's mood.

"Can I ask a few questions?" Chen Yidao.

Dr. Wu tilted his head, which was considered a arrogant acquiescence.

The first thing Chen Yi mentioned was the salary situation of the institute. Dr. Wu did not hide it. The starting salary is 8,000, assistant researcher starts at 10,000, and a researcher can basically reach 20,000.

Fan Zhimei's salary is more than 20,000 yuan now, and it has gradually increased due to years of work, so the average salary is 20,000 yuan.

"Do assistants need a Ph.D. degree?" Chen Yi was a little surprised.

Dr. Wu is proud: "Of course, not everyone can get into our institute. Nowadays, academic qualifications are becoming less and less valuable. It is very common to graduate with a doctorate."

Chen Yi nodded slightly: "That's true."

A few decades ago, junior college students were considered smoke from their ancestral graves. Now there are so many graduate students, undergraduates are everywhere, and Ph.D.s are not uncommon.

If it's 20,000...

Fan Zhimei had to go without food or drink for 130 months, nearly eleven years.

She is almost 30 years old after graduating with a doctorate. Under normal circumstances, Fan Zhimei would not be able to save a huge sum of 2.6 million, unless she has other sources of income or money from her family.

The bank can check the bank statements for five years. No relatives have transferred money to her, and no side business has been found.

Chen Yi was straightforward: "Can Fan Zhimei freely use scientific research funds?"

"Can't...why do you ask this?" Dr. Wu became more energetic, and the topic was a bit sensitive.

Chen Yi: "Is it completely impossible? Can you think of a way?"

He did not mention Fan Zhimei's transfer of more than two million yuan to her boyfriend for the time being. In case the other party was not a murderer and the source of funds was legal, privacy needed to be protected.

Dr. Wu obviously understood, and asked knowingly: "Captain Chen, what exactly do you want to say?"

Chen Yi repeated: "Literally, can special methods be used to control part of the funds in the institute? I will investigate this matter even if Dr. Wu doesn't tell me. Let's try not to make it so complicated and be more harmonious."

The topic is indeed a bit sensitive.

If even Fan Zhimei has a way to mobilize funds, then the director's authority will only be greater.

On the surface, they are talking about Fan Zhimei, but in fact, it is possible to involve Dr. Wu, but Chen Yi is willing to believe that there is something wrong with the other person's character. He should be smiling when he sees him, and Dr. Wu obviously does not look like a cunning person.

Even if it was, it was not the job of the criminal investigation detachment. He would not think about it for no reason.

He only cares about the current murder case.

Seeing that Chen Yilai was serious and had a warning, Dr. Wu was silent for a moment and said: "It can be done, but it is strictly prohibited. Once found, not only will he be expelled, but he will also be handed over to the public security organs for processing. No one dares."

Chen Yi also learned to ask: "Killing will be punished by death, and drug trafficking will be punished by death. Does Dr. Wu think the world is peaceful?"

"Uh." Dr. Wu couldn't refute. After taking a deep look at Chen Yi, he took out his mobile phone and dialed the number. His voice lowered, "It's me. Go check it out right away..."

Chen Yi, who was behind him, didn't hear clearly, so he smiled and said, "Excuse me, Dr. Wu. It saved us a lot of effort."

Dr. Wu snorted: "I just don't want you to lead people to surround the institute and make it a mess."

Chen Yi: "No, definitely not. You and the scholars in the institute have made outstanding contributions to the country, and we should respect them. Personally, I admire you even more. I just graduated with a bachelor's degree, so I can't compare."

Dr. Wu looked relaxed and seemed to like hearing this.

Say as much as you like, and Chen Yi was not stingy. He continued to praise Dr. Wu until he raised the corners of Dr. Wu's mouth. It seemed that Chen Yi was beginning to like Chen Yi.

Chen Yi was thinking, if you were put into a private company or an administrative position for two days, you might not have room to cry.

Nowadays, some highly educated people like to stay in universities or engage in research. The main reason is that they do not want to deal with complex interpersonal relationships.

I have my undergraduate degree in school, my master's degree in school, and no matter how hard I work, I will still have my Ph.D. in school. After graduation, I will continue to stay in school, and I will not have to enter the society for the rest of my life, which is very comfortable.

Compared with primary and secondary schools, the career pressure in college is very small.

Qin Fei was holding back his laughter all the time. It was very hard. This doctor had a very high IQ, but his emotional intelligence was really hard to compliment. It was too easy to fool. I don’t know how he became the director. Maybe it was all about talent or someone else.

While chatting, Chen Yi turned the topic to the Amanita ghost pen, without mentioning that it was a murder weapon, just making small talk.

"Amanita phalloides, I know." Dr. Wu put on a smile, "It is called death cap abroad. Compared with other fungi, it is medium and large in size. It has a smooth surface and a spherical base. It contains highly toxic peptides and cannot be eaten. ”

Chen Yi: "Is there any in the office?"

Dr. Wu: "Yes."

Chen Yi's eyes fluctuated and he asked: "There are also fungi? Are they specially raised?"

Dr. Wu: “Yes, there is an intersection between fungi science and plant science.”

Chen Yi: "What's the use?"

When it came to Dr. Wu's major, he began to talk at length. I have to say that there are specialties in the field, which must be admired. It can replace the encyclopedia, and it is more detailed and in-depth.

There are generally five purposes for studying fungi.

The first is the medical value. After research and transformation, the components of some highly poisonous mushrooms may be used to develop new drugs.

Dr. Wu also gave the example of a certain type of fungal toxin that has been found to inhibit the growth of tumor cells and even modulate the immune system to target AIDS.

The second is ecological research. Studying fungi helps to understand the balance and operation of the ecosystem and reveals the structure and function of the ecosystem.

The third is food safety. Studying fungi can assist relevant departments in formulating more accurate food safety standards to prevent people from eating by mistake.

The fourth is species identification and classification, which improves the knowledge system of mycology and indirectly helps improve botany.

Finally, there is the study of evolution. This topic is relatively deep. Chen Yi was a little confused by what Dr. Wu said, such as the mechanism of the evolutionary process, the theory of biological evolution, etc. The chat almost turned into a class.

Chen Yi found a good time to interrupt and asked Fan Zhimei if he could access it and whether there was an accurate quantity of this mushroom.

Dr. Wu said that everyone in the institute can have access to it, but there is no exact number. It is difficult to tell whether it is more or less.

Chen Yi thought about the feasibility of Fan Zhimei poisoning.

I went to Gong Qingliang's house at around ten o'clock in the evening. He probably didn't have poisonous mushrooms hidden on his body and fried them for him to eat, right? A little deliberate.

If it could be extracted... it would be much simpler.

"Dr. Wu, can you extract phagocytosin from Amanita phalloides?"

Dr. Wu nodded: "Of course this is my specialty. For us, the extraction of cyclic peptide toxins is just like a doctor treating a disease while you investigate a case. It is very simple."

"Moreover, this cyclic peptide toxin still has the property of stabilizing microtubules after being fluorescently labeled, so it has been widely used in biomedical research to display the morphology and distribution of intracellular microfilaments. "

Chen Yi didn't understand it at all, and simply thought that the other party was talking about Aba Aba, Aba Aba.

He continued to ask: "What is the extracted form? Liquid? Solid?"

Dr. Wu blurted out: "Powder, white powder."

Chen Yi's eyes narrowed slightly: "Is this something included in Fan Zhimei's work content?"

Dr. Wu subconsciously said: "No, she is currently focusing on the utilization of plant resources, and there will be a breakthrough soon... huh?"

No matter how slow he reacted, he still came to his senses.

"Captain Chen, what do you mean?"

Chen Yi said without doubt: "Dr. Wu, our technical investigators need to conduct a comprehensive investigation of Fan Zhimei's laboratory. Please cooperate. Also, regarding funding issues, please give me the results as soon as possible."

Without his instructions, Qin Fei immediately took out his mobile phone.

Dr. Wu's face turned dark again. He felt that this young man was full of "bad things."
