Chapter 527 Fan Zhimei's Difficulty

When Qin Fei called, Lu Yongqiang was wiping DNA and toxins from each cup at Gong Qingliang's house to look for fingerprints, very seriously.

As for DNA, except for highly recognizable biological traces such as blood and hair, everything else depends on luck and guesswork.

For example, a cup that has been drunk by a person will be attached to the oral mucosa, which cannot be seen by the naked eye. It needs to be wiped and sent back to the bureau for testing, which is a test of the professional skills of the on-site investigation.

Some on-site investigations believe that there may be DNA here, while others believe that there is no DNA, thus ignoring important clues.

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

"Team 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-investigation and took people and equipment to rush there.

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

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

An hour later.

Fan Zhimei's laboratory became lively. The technical detectives conducted a carpet search of every corner, focusing on experimental equipment, especially equipment that can extract fungal toxins. Fang Shuyu was in charge of this matter wearing a mask.

At the door, Qin Fei led people to stand guard to prevent any irrelevant personnel from approaching.

The window was relatively free. At this moment, it was crowded with researchers watching, and whispers were endless.

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

The laboratory has been checked, and this question is a bit redundant.

Chen Yi said: "Dr. Wu, please be patient. This is a routine investigation. We only look at the results. By the way, haven't you found out the funding issue? Is there anything missing?"

In an hour, it should be found out.

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

"Less?" Chen Yi frowned, "Why didn't you say it earlier? How much is missing?"

Dr. Wu: "One million...800,000."

Chen Yi: "Please explain clearly, how is it less, who took it, was it Fan Zhimei."

Dr. Wu helplessly: "It should be, she took the money according to the procedure, but the account doesn't match."

Chen Yi looked at him: "There is a problem with your management, and you didn't find it."

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

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

Even if she didn't kill anyone, she would have to go to jail for embezzling research funds.

Dr. Wu had a headache and didn't want to argue with Chen Yi. If Fan Zhimei went to jail, he couldn't escape dereliction of duty.

The investigation lasted until the evening, the technical investigation team was withdrawn, and Chen Yi returned to the Municipal Bureau to wait for the inspection results.

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

It should have been cleaned, but it was not cleaned up.

Powdered objects are relatively stable and easy to scatter a little. It is difficult to completely remove them even with a big cleaning. It is the same as flour. A light blow will fill the room.

"Bring the person out and bring him to trial immediately."

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

The cold chair, without the restraint of freedom, Fan Zhimei was still 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 residue in your laboratory. You have the ability to extract amanita phalloides from Amanita phalloides."

"From the time when Gong Qingliang was poisoned, he took poison the day before the incident, and you happened to have been to his house."

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

It is a relatively complete chain of evidence. If there were no other three women, it would be enough to submit it to the procuratorate for prosecution.

In the current situation, it is still necessary to get Fan Zhimei's confession, otherwise if she is smart or has a lawyer's guidance, she can change her confession in court.

If the suspect successfully changes his confession in court, the procuratorate will be embarrassed, and it will eventually be sent back to the municipal bureau for re-investigation, and the embarrassment will still be the criminal investigation detachment.

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

Chen Yi tapped the report with his fingers: "Isn't it? You took 1.8 million from the station. When you learned that Gong Qingliang was a scumbag and a liar, you had a very sufficient 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 sank 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 back: "Are you so sure that I killed him? That day, besides me, no one else went to Qingliang's house?"

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

Before the interrogation, Chen Yi asked the police officer in charge of monitoring that the four people had not chatted in the detention room, except Luna told Bao Linlin to shut up and stop crying, and never said a word.

Does Fan Zhimei know the existence of the other three women?

Since she committed the act of killing, it can be judged that she already knew, so she was so angry that she lost her mind.

In Fan Zhimei's opinion, the police didn't know that she already knew that three other people had been to Gong Qingliang's home besides herself, so they could only guess.

If the police conducted a comprehensive investigation of Gong Qingliang, they would definitely find out.

However, no matter what Fan Zhimei thought, Chen Yi thought that there was something wrong with her suddenly asking whether other people had been to Gong Qingliang's home.

Could it be that she had a comprehensive grasp of Gong Qingliang's dynamics?

Or was it just a casual question?

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

False confession is likely to make her lose face.

Seeing Chen Yi fall into a brief silence, Fan Zhimei continued: "I extracted amanita phalloides, which is my specialty. Although it is not my job, can't I expand 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 only Qingliang and I met the day before the incident."

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

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

When an introverted woman suddenly talks to the police, her logic is clear, and there is no need to think about it. She must have prepared in advance.

Chen Yi basically locked in that Gong Qingliang's death was her fault, but the appearance of Luna and the other two made the case difficult to handle.

Innocent until proven guilty.

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

This woman is very smart.

There is no point in asking where the amanita phallus has gone. Fan Zhimei must have thought of all the excuses. Just say "lost".

No matter 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?

Yes.

Fan Zhimei did extract the amanita phallus, but she did not use it to kill people. The murderers were Luna, Bao Linlin or Cao E.

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

Chen Yi did not expect that Fan Zhimei's appearance is not what she seems. He turned around and left the interrogation room with great seriousness.

Fan Zhimei can be detained for criminal offenses based on the misappropriation of funds from the institute, and then be directly investigated by the procuratorate.

Because Fan Zhimei is affiliated with a state-owned unit, there is no need to go through economic investigation.

Before that, the murder case must be confirmed first.

The case handling hall was brightly lit, and no one dared to breathe, let alone leave work. Anyone could see that Chen Yi was in a bad mood at the moment.

Fan Zhimei, this is a trick for the criminal investigation detachment, it's hard to deal with.

Obviously, she has been planning for a long time, making Gong Qingliang's other women the biggest reliance for her to escape the crime.

There is no clear process of committing the crime, and the 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 it is not a very clear fact and very clear iron evidence, there is a possibility of wrong judgment.

Chen Yi smoked a cigarette and thought about the breakthrough.

Conspiracy is not terrible, but overt conspiracy is a bit of a headache.

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

Qin Fei beside him responded: "Murder is a felony, and 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, it will be difficult to say in court."

Lin Chen: "Can you find a way to prove that the other three did not poison?"

Qin Fei: "How to prove this?"

Lin Chen didn't say anything, he just wanted to know.

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

Chen Yi: "Let's release them when the time is up... It's a bit strange. Why don't the four people, Luna, chat? They really can't hold it in."

He Shixin said: "One was scared and cried, an introverted doctor, a cold company executive, and Luna who doesn't like everyone. It's normal that they don't chat."

Chen Yi flicked the ash: "Don't make subjective explanations first, make an assumption, what if Luna and the other three knew about it, is it really such a coincidence? Four people went to Gong Qingliang on the same day, has this happened before?"

Fan Zhimei asked that question, which means that she should know that someone else went to Gong Qingliang's house the day before the incident.

How did she know? She didn't leave the institute all day.

It may be some technical means, or they may have communicated with each other.

"This..." He Shixin shook his head, "I haven't checked it in detail yet, shall I check it now?"

Chen Yi hummed, "Let's check it out."

If there is any doubt, we must investigate it. Now we need to pay more attention to the details. There is definitely nothing new in the general direction. Poisoning at the door is just this matter. It's not complicated.
