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

Chapter 527 Fan Zhimei's Difficulty

When Lu Yongqiang received Qin Fei's call, he was wiping DNA and toxins from each cup at Gong Qingliang's house, looking for fingerprints very seriously.

As far as DNA is concerned, apart from highly recognizable biological traces like blood and hair, the rest is all based on luck and guesswork.

For example, cups that people have drunk from will have oral mucosa attached, which is invisible to the naked eye and needs to be wiped and sent back to the bureau for testing, which is a test of the professional skills of the on-site surveyor.

Some on-site surveys believe that there may be DNA here, while others believe that there is not, thus ignoring important clues.

Lu Yongqiang's re-survey work has just been completed halfway.

"Captain Chen said to come to the institute immediately."

Qin Fei said.

Chen Yi's order was urgent. After hearing it, Lu Yongqiang immediately gave up the on-site re-survey and rushed there with his men and equipment.

In addition to Lu Yongqiang, Fang Shuyu also received the notice.

Forensic medicine also falls under the category of technical investigation, but it is relatively independent in the municipal bureau, and the situation of each unit may be different.

after an hour.

Fan Zhimei's laboratory became bustling with activity. Technical detectives conducted a carpet search of every corner, focusing on experimental equipment, especially equipment that could extract fungal toxins. Fang Shuyu, wearing a mask, was personally in charge of this matter.

At the door, Qin Fei and his men stood guard to prevent any unrelated personnel from approaching.

The window was relatively free, as it was now crowded with researchers watching and the sound of whispers could be heard everywhere.

"Captain Chen, come on, come on..." Dr. Wu couldn't bear to watch any longer and pulled Chen Yi to a deserted place. "Was the deceased poisoned by a cyclopeptide toxin? Has it been confirmed?"

The laboratory inspection has already begun, so this question is a bit redundant.

Chen Yi said, "Dr. Wu, please be patient. This is a routine investigation and we are only looking at the results. By the way, haven't you figured out the funding issue yet? Is there anything missing?"

It should take an hour to find out.

Hearing this, Dr. Wu's face turned unnatural, and he gritted his teeth and said, "It is indeed less."

"It's missing?" Chen Yi frowned. "Why didn't you tell me earlier? How much is missing?"

Dr. Wu: "One million... eight hundred thousand."

Chen Yi: "Please explain clearly, how did it become missing? Who took it? Was it Fan Zhimei?"

Dr. Wu was helpless: "It should be. She took the money according to the procedure, but the accounts don't match."

Chen Yi looked at him and said, "There is something wrong with your management. You didn't even notice this."

Dr. Wu: "This has never happened in decades. No one would have thought she was so bold."

Chen Yi said no more and asked the other party to prepare the relevant materials and be mentally prepared, as Fan Zhimei might not be able to come back.

Even if he didn't kill anyone, he would still be charged for embezzling research funds.

Dr. Wu had a headache and had no energy to argue with Chen Yi. If Fan Zhimei went to jail, he would not be able to escape the charge of dereliction of duty.

The investigation lasted until the evening. After the technical investigation team was dismissed, Chen Yi returned to the Municipal Bureau to wait for the test results.

Nearing twelve o'clock, the results came out and the drowsy Chen Yi was awakened. Residual amanita phalloides was detected in Fan Zhimei's laboratory, but the amount was extremely small, at a trace level.

It should have been cleaned, but it wasn't.

Powdered objects are relatively stable and easy to scatter. They are also difficult to completely remove even with a thorough cleaning. It's the same as flour, which will fill the room with just a slight blow.

"Bring the man out and interrogate him immediately."

Chen Yi went to wash his face, and when he opened the door and walked into the interrogation room, Fan Zhimei was already sitting there.

Sitting on the cold chair and without the restraints of freedom, Fan Zhimei remained as silent as an ancient well, without any uneasiness.

Chen Yi walked straight to Fan Zhimei and took out the test report: "Fan Zhimei, I won't talk to you about anything else. Gong Qingliang died of Amanita phalloides poisoning. Amanita phalloides were cultivated in the institute, and we found Amanita phalloides powder residues in your laboratory. You have the ability to extract Amanita phalloides from Amanita phalloides."

"Judging from the time when Gong Qingliang took the poison, he took the poison the day before the incident, and you happened to have been to his home."

"All the clues and evidence are in front of you, do you admit it?"

It's a relatively complete chain of evidence. If it weren't for the other three women, it would be enough to submit it to the procuratorate for prosecution.

Under the current circumstances, we still need to get Fan Zhimei's confession. Otherwise, if she is smart or has the guidance of a lawyer, she can change her confession in court.

If the suspect successfully changes his confession in court, the procuratorate will be very embarrassed and the case will eventually be sent back to the municipal bureau for reinvestigation, and the Criminal Investigation Detachment will be the one to be embarrassed.

Facing Chen Yi's questioning, Fan Zhimei glanced at the test report and did not react much: "You suspect that I killed him."

Chen Yi tapped the report with his fingers: "Isn't it? You took 1.8 million from the institute. When you learned that Gong Qingliang was a scumbag and a liar, you had a very good motive to commit the crime, not to mention that the evidence is here."

"Liar?" Fan Zhimei was puzzled. "What did he lie to me about?"

Chen Yi's eyes darkened slightly, and he said coldly: "You don't admit it, right?"

Fan Zhimei looked at Chen Yi with a puzzled and innocent look and asked, "Are you so sure that I killed him? Was there no one else who went to Qingliang's house that day besides me?"

This made Chen Yi raise his eyebrows, and his eyes narrowed habitually, and he began to re-examine Fan Zhimei.

Before the interrogation, Chen Yi asked the police officer in charge of surveillance. The four of them had not chatted in the detention room. Except for Luna asking Bao Linlin to shut up and stop crying, no one else said a word.

Did Fan Zhimei know about the other three women? Since she committed the murder, it can be judged that she knew about it, which is why she was so angry that she lost her mind.

As far as Fan Zhimei knew, the police did not know that she already knew that besides herself, three other people had been to Gong Qingliang's home, and they could only guess.

If the police conduct a comprehensive investigation into Gong Qingliang, they will definitely be able to find out.

However, no matter what Fan Zhimei thought, Chen Yi thought there was something wrong when she suddenly asked whether anyone else had been to Gong Qingliang's house.

Could it be that she has a comprehensive grasp of Gong Qingliang's movements?

Or, just a casual question?
In this situation, after weighing the pros and cons, Chen Yi could not give the answer "No one has been there except you". He felt that there was something about this woman, and it didn't seem like she was just talking casually.

False confession may very likely lead to you losing face.

Seeing Chen Yi fall into a brief silence, Fan Zhimei continued, "I extracted amanita phalloides. This is my specialty. Although it is not my job, can't I expand on it in my spare time? Isn't it illegal?"

"Comrade police officer, the evidence you provided can only prove that I extracted Amanita phalloides, but it cannot prove that I used Amanita phalloides to kill Qingliang, unless you can prove that Qingliang and I were the only ones who met the day before the crime."

"I am sure I didn't do it, so someone else must have been to Qingliang's house that day. You have to check it out."

During the first interrogation, Fan Zhimei didn't say so much.

When the introverted woman suddenly spoke eloquently and logically in front of the police, it was obvious that she had prepared in advance.

Chen Yi has basically determined that Gong Qingliang's death was caused by her, but the appearance of Luna and the other two makes the case more difficult to handle.

Innocent until proven guilty.

When clues cannot accurately point to a person, the final judgment must be in favor of the person involved. This is clearly stipulated by law.

This woman is very smart.

There is no point in asking where the Amanita phalloides has gone. Fan Zhimei must have thought of all the excuses, and all she needs to do is reply "it's lost".

Regardless of whether the logic is valid or not, as long as it cannot be falsified, it is the current fact.

To put it simply and bluntly, could Luna and the other two be the murderers?
Have.

Fan Zhimei did extract amanita phalloides, but she did not use it to kill people. The people who were killed were Luna, Bao Linlin or Cao E.

If this possibility cannot be ruled out, Fan Zhimei cannot be convicted.

Chen Yi didn't expect that Fan Zhimei was not a person to be judged by appearance. He became extremely serious and turned to leave the interrogation room.

Fan Zhimei can be criminally detained solely on the charge of misappropriating institute funds, and then handed over to the procuratorate for direct investigation.

Because Fan Zhimei worked for a state-owned unit, there was no need for economic investigation.

Before that, the murder case must be confirmed.

The lights in the case handling hall were on brightly. No one dared to breathe, let alone leave work. Anyone could see that Chen Yi was not in a good mood at the moment.

Fan Zhimei, this is a trick for the Criminal Investigation Detachment, it's going to be difficult to deal with.

Obviously, she had been planning for quite some time and made Gong Qingliang's other women her biggest reliance to escape punishment.

There is no clear process of the crime, and all four women are suspected of poisoning, so Fan Zhimei is safe.

In court, the trial committee only looks at the evidence. After all, as long as there are not extremely clear facts and extremely clear and hard evidence, there is a possibility of a wrong verdict.

Chen Yi smoked a cigarette and thought about a breakthrough.

Conspiracies are not scary, but open conspiracies are a bit of a headache.

"Isn't this a bit shameless?" Lin Chen whispered in the crowd.

Qin Fei beside him responded: "Murder is a serious crime, playing rogue is nothing. In this case, even if it can be proved that Fan Zhimei brought poison into Gong Qingliang's house, as long as it cannot be proved that she poisoned him, it will be difficult to say in court."

Lin Chen: "Can you find a way to prove that the other three didn't poison me?"

Qin Fei: "How do you prove this?"

Lin Chen didn't say anything, it would be good if he just knew.

After a long time, He Xin asked, "Captain Chen, what about Luna and the others? Have they been released? It will be 24 hours after dawn."

Chen Yi: "Let's play it when the time is up... It's a bit strange, why aren't Luna and the other four chatting? They really can't hold it in."

He Shixin said: "One is crying out of fear, an introverted doctor, a cool company executive, and Luna who doesn't like everyone. It's normal for them not to chat."

Chen Yi flicked the ash from his cigarette. "Don't make a subjective interpretation first. Let's make an assumption. What if Luna and the other three knew about this? Is it really such a coincidence? Four people went to see Gong Qingliang on the same day. Has this happened before?"

The fact that Fan Zhimei asked that question shows that she should have known that someone else had been to Gong Qingliang's home the day before the incident.

How did she know? She hadn't left the institute all day.

It could be some technical means, or it could be communication between each other.

"This..." He Shixin shook his head, "I haven't checked it specifically. Should I check it now?"

Chen Yi hummed: "Let's make it happen."

When in doubt, we must investigate. Now we need to pay more attention to details. There is definitely nothing new in the general direction. It is just a matter of poisoning someone's home. There is nothing complicated about it.
