Detective: Open your eyes, I am handcuffed in the interrogation room.

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-inspection.

Since four women came the day before the incident, the search for clues must be comprehensive.

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, crime scenes are complex and diverse, and no matter how advanced the trace detection technology is, it cannot guarantee 100% perfection.

There is a reason why the afternoon was chosen as the time point. Some previously unnoticed traces may appear under different lighting, angles, and other conditions.

The most important thing is that the cause of death of the victim Gong Qingliang has been found, and trace inspection needs to be done again in a targeted manner, such as cups, bowls, plates and other tableware, in the hope of determining how the poison entered the body.

Chen Yi was still watching the real-time surveillance of the interrogation. There had been no breakthrough so far, no one had revealed any flaws, and there were no inconsistencies in the answers.

Everyone was the same, contacting in advance, going upstairs, meeting, chatting, and being intimate. Bao Linlin and Cao E also accompanied Gong Qingliang for lunch and afternoon meals.

The interrogation lasted for more than two hours. All the questions that needed to be asked had been asked, but it seemed that no one was willing to confess. 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 took the poison, these four women are highly suspicious and meet the procedural standards for temporary detention.

He Xin asked: "Will he be locked up alone?"

The number of detention rooms is allocated based on factors such as the city's population size, public security conditions, and the number of cases. In principle, each police station should have at least one detention room, and the municipal bureau should have more, so it is not a problem to detain four people alone.

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

Does anyone know that Gong Qingliang is actually a love cheater? If only one person knows, then the other person is more likely to be the perpetrator.

If we put them together, maybe we can see something.

"Okay." He Xin went to make the arrangements.

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

Bao Linlin cried again, this time not for her boyfriend but for herself. It was the first time for the young girl to go to the Public Security Bureau and be put in a detention room. She must have been anxious and panicked.

She wanted to call her father, but He Shixin did not agree after asking Chen Yi. She would naturally contact the family when the time came.

The detachment held a meeting.

Chen Yi didn't waste any time and directly arranged the next investigation task, digging deeper into more information about the four people, including but not limited to their mobile phones, computers, homes, private lives, financial status, etc.

Premeditated murder takes time, not only time for psychological struggle, but also time to prepare the conditions for the crime.

Look for anomalies to indirectly determine who is the one who poisoned.

"Captain Chen, the research institute is not easy to deal with. If you lead people to investigate, there may be resistance."

At the meeting, Zhuo Yun briefly talked about what had happened in the institute before. Scientists are different from ordinary people, so communication is a bit difficult and needs to be handled with caution.

Senior national intellectuals have certain privileges.

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

Qin Fei nodded: "Yes."

Chen Yi: "Others, if you have any major discoveries, please call us immediately. The investigation will begin immediately. Let's get busy."

"Yes!"

Everyone stood up and left the meeting room.

Chen Yi was the last to leave, and he led his men straight to the research institute.

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

Two million six hundred thousand is not a small sum. We will know whether she can earn this money by checking.

If not, then Fan Zhimei had financial problems and had a stronger motive for committing the crime.

She took huge risks to help her future husband through the crisis, but in the end she found out that she had been cheated. It is not surprising that she did anything in anger.

Detention room.

It was very quiet, with only Bao Linlin's sobbing echoing around. The four people sat 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 stopped crying abruptly and covered her mouth.

She was very obedient, perhaps because she was afraid of the people who were also imprisoned. She didn't know what crimes they had committed. The unknown was the biggest fear. What if there was a perverted murderer?
Luna said this and then retracted her gaze, continuing to keep her head down in silence. The detention room became even quieter.

There were people guarding the door and watching the surveillance cameras, but the police were actually more willing to let the guys chat.

As long as Gong Qingliang is talked about, the scene will be very exciting, and there will be more loopholes, but unfortunately no one spoke first.

……

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 research and control of crop pests, plant breeding and pollination, etc. It is more public welfare-oriented and the state provides scientific research funds.

This research institute has been in Yangcheng for sixty years.

Chen Yi has already obtained the basic information. There are 60 employees and 50 technical personnel. 30 of them have doctoral degrees. The technical personnel are at least postgraduate students. It can be said that this is a gathering place for highly educated talents.

"okay, I get it."

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

The place is special, so he needs to seek the opinions of the provincial department. For example, what to do if there is resistance to investigation? The provincial department said they should try to maintain harmony and avoid a rift.

If fifty scientists and thirty PhDs really unite, it will be a headache for the provincial department. There is no need for Chen Yi to offend national talents because of a case.

Since he is highly educated, he should cooperate and not act like a rogue.

After entering the station and showing his ID, Chen Yi met the director. They both had the same rank, both deputy director.

Instead of being as polite as expected, the director's face looked a little dark.

"Captain Chen, didn't you just take the person away? Why are you here in person again?"

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

The other party's men took Fan Zhimei away, so he was naturally not in a good mood.

Chen Yi sighed: "Dr. Wu, this is a murder case, please bear with me."

"I know about the murder." Dr. Wu didn't smile. "Did she really do it? Don't make any mistake."

Chen Yi said: "It may not be her, but she is a strong suspect. We need to do further investigation, so..."

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

Chen Yi: "Of course we have a reason to come here."

Dr. Wu: “What’s the reason?”

Chen Yi: "..."

This person likes to ask rhetorical questions.

In the process of communication between people, rhetorical questions are the most effective in affecting the other person's mood.

"Can I ask a few questions?" Chen Yi asked. Dr. Wu turned his head away, a proud acquiescence.

The first thing Chen Yi mentioned was the salary situation at the institute, and Dr. Wu did not hide it. The starting salary was 8,000, the starting salary for assistant researchers was 10,000, and the salary for researchers could basically reach 20,000.

Fan Zhimei's current salary is over 20,000, which has slowly increased over the years of work, so it's an average of 20,000.

"Does an assistant need a PhD degree?" Chen Yi was a little surprised.

Dr. Wu proudly said: "Of course, not everyone can enter our institute. Nowadays, academic qualifications are becoming less and less valuable, and it is common to graduate with a doctorate."

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

Decades ago, having a junior college degree was considered a rarity, but now there are countless graduate students, undergraduates everywhere, and PhDs are not uncommon.

Twenty thousand...

Fan Zhimei needs to work without eating or drinking for 130 months, which is nearly 11 years.

When she graduated with a Ph.D., she was almost 30 years old. Under normal circumstances, it would be impossible for Fan Zhimei to save a huge sum of 2.6 million yuan unless she had other sources of income or her family gave her money.

The bank was able to check five years of bank statements and found no relatives had transferred money to her, nor was any side business discovered.

Chen Yi asked directly: "Can Fan Zhimei freely dispose of the research funds?"

"No...why are you asking this?" Dr. Wu became more alert, and the topic was a bit sensitive.

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

He did not mention the fact that Fan Zhimei transferred more than 2 million yuan to her boyfriend for the time being. In case the other party was not the murderer and the source of funds was legal, privacy needed to be protected.

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

Chen Yi repeated: "Literally, can special methods be used to control part of the institute's funds? I will investigate this matter even if Dr. Wu doesn't say it. Let's try not to make it so complicated and be 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 were talking about Fan Zhimei, but in fact, it was possible that Dr. Wu would be involved as well. However, Chen Yi was willing to believe that the other person was a good person. If there was really something wrong with him, he should have smiled when meeting him. However, Dr. Wu obviously did not look like a cunning person who was good at dealing with people.

Even if it was, that was not the job of the Criminal Investigation Brigade. He would not think about it that way for no reason.

He only cares about the current murder case.

Seeing that Chen Yi 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 discovered, not only will you be fired but you will also be handed over to the public security authorities. No one dares to do that."

Chen Yi also learned to ask back: "Murder will be sentenced to death, drug trafficking will be sentenced to death, Dr. Wu, do you think the world is peaceful?"

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

Chen Yi at the back didn't hear clearly, he smiled and said, "Thank you for troubling Dr. Wu, it saves us a lot of effort."

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

Chen Yi: "No, definitely not. You and the scholars in your institute have made outstanding contributions to the country. We should respect you. Personally, I admire you even more. I have only graduated from college, so I can't compare with you."

Dr. Wu's expression relaxed and he seemed to like what he heard.

If you like to hear it, just say more. Chen Yi was not stingy and continued to praise him a few more times until Dr. Wu's mouth corners raised, as if he began to like Chen Yi.

Chen Yi was thinking, if you were put in a private enterprise or an administrative position and worked for two days, you would probably have no place to cry.

Nowadays, some highly educated people like to stay in universities or do research, the main reason is that they don’t want to deal with complex interpersonal relationships.

I studied undergraduate at school, I studied master's at school, and if I work hard, I can also get my doctorate at school. After graduation, I will stay in school and never have to enter the society. It is very comfortable.

Compared with elementary and middle schools, career pressure in college is very small.

Qin Fei was trying hard to hold back his laughter. This doctor had a high IQ, but his EQ was really low. He was too easy to fool. I don't know how he became the director. Maybe it was all because of his talent or maybe he had connections.

As they chatted, Chen Yi turned the topic to the Amanita phalloides. He didn't say it was the murder weapon, but just kept chatting.

"Amanita phalloides, I know." Dr. Wu smiled. "It's called the death cap in foreign countries. It's medium to large in size compared to other fungi, with a smooth surface and a spherical base. It contains highly toxic peptides and can't be eaten."

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

Dr. Wu: “Yes.”

Chen Yi's eyes wavered for a moment, and he asked, "Do you have fungi? Are they specially cultivated?"

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

Chen Yi: "What's the use?"

When it came to Dr. Wu's major, he began to speak at length. It has to be said that every profession has its own expertise. This is something we must admire. It can replace an encyclopedia and is more detailed and in-depth.

There are generally five purposes for studying fungi.

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

Dr. Wu also gave an example. Research has found that a certain fungal toxin can inhibit the growth of tumor cells and even regulate the immune system to target AIDS.

The second is ecological research. Studying fungi helps us understand the balance and operation of ecosystems and reveal the structure and function of ecosystems.

The third is food safety. Research on fungi can assist relevant departments in formulating more accurate food safety standards to prevent people from accidentally eating them.

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

The last topic was evolutionary research. This was a rather deep one and Chen Yi was a little confused by what Dr. Wu said, such as the mechanism of evolutionary process, theory of biological evolution, etc. The conversation almost turned into a class.

Chen Yi found a good opportunity to interrupt and asked Fan Zhimei if she could get access to it and whether there was an exact quantity of this kind of mushroom.

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

Chen Yi pondered the feasibility of Fan Zhimei's poisoning.

I went to Gong Qingliang's house at around 10pm. I don't think I would hide poisonous mushrooms on my body and fry them for him to eat, right? It was a bit deliberate.

If it could be extracted...it would be a lot simpler.

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

Dr. Wu nodded: "Of course, this is my specialty. For us, the extraction of cyclic peptide toxins is as simple as a doctor treating a disease and you investigating a case. It's very simple."

"Moreover, this cyclic peptide toxin still has the property of keeping microtubules stable after fluorescent labeling, so it has been widely used in biomedical research to display the morphology and distribution of microfilaments in cells."

Chen Yi didn't understand at all and just thought the other party was just saying "baba, aba, aba".

He continued to ask: "What is the property of the extracted product? Liquid? Solid?"

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

Chen Yi's eyes narrowed slightly: "Does Fan Zhimei's job include extracting this thing?"

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

Even though he was slow to react, he finally came to his senses.

"Captain Chen, what do you mean?"

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

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

Dr. Wu's face darkened again. He felt that this young man was full of bad intentions.
