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

Chen Yi nodded: "You can say that."

"If he just wanted to get close to Ding Zi, so he put diazepam drugs in the wine, then he could have handed the wine directly to Wang Lihua without going through Ding Zi."

"We are all sitting together. Even if we are not next to each other, we can just stand up and stretch out our hands, just like handing them to me and Jiang Fanlei. Why bother?"

"What if Ding Zi drinks the wine directly after taking it, or refuses to hand it to Wang Lihua and asks Yuan Lihao to get another bottle?"

"There are variables, but it's not as safe as giving it to Wang Lihua directly."

"He received the invitation notice on Tuesday, and he should have been preparing in the intervening days. Why not choose a safe way when the final step is made?"

"Thinking about it, if it were me, I would definitely choose to hand it directly to Wang Lihua."

"If you hand it to Ding Zi first...unless she knows what Yuan Lihao wants to do in advance."

"But judging from Ding Zi's reaction just now, we don't know."

"This is the second point I want to make. Why doesn't she know? Isn't this kind of thing communicated in advance?"

Zhuo Yun hesitated: "But if he wants to kill Wang Lihua, how can he ensure the success rate?"

"It is indeed difficult for diazepam drugs to poison people, even if Wang Lihua has underlying diseases."

"Is it possible that it's just a matter of luck? It's best if you can kill him. If you can't kill him, let's wait until next time."

Zhou Yebin asked: "Is it possible that Wang Lihua died before Yuan Lihao took action?"

The two turned their heads.

Zhou Yebin continued: "Yuan Lihao wants Wang Lihua to fall asleep first, and then take advantage of the opportunity to take action."

"But what surprised him was that the person died before he could take action. Was it God's favor?"

Zhuo Yun: "It seems...if we don't rule out this possibility, it would be difficult to handle."

"The problem now is that we can't tell whether Wang Lihua died of homicide."

"If you can't even figure this out, how can you even talk about investigating?"

Hearing this, Chen Yi said: "The autopsy must not be over yet. I will call Shuyu to discuss it later."

"I personally think there is something wrong with the red spots around Wang Lihua's mouth and nose."

"Huh?" Zhuo Yun was surprised, "Do you still know about autopsy?"

Chen Yi nodded: "I know a little bit, and I have read more complicated books."

Zhuo Yun: "..."

After a moment of silence, he couldn't help but say: "What else do you want? Can you tell me all at once? Don't act like squeezing out toothpaste."

Chen Yi: "Ability is used, not spoken."

"Do you know when red spots will appear? Mechanical asphyxia caused by external force."

"Of course, this is theoretical."

Zhuo Yun was surprised: "External force? Impossible, no one has time to commit the crime."

Chen Yi: "So we have to continue investigating and rule out all possibilities."

"If Wang Lihua really died of normal circumstances, we have fulfilled our police duties."

"Team Zhou, I suggest a thorough investigation of Wang Lihua."

Hearing this, Zhou Yebin raised his eyebrows: "You want to start with the motive for committing the crime?"

Chen Yi hummed: "The elements of a murder include the motive, means, location, and time of the crime."

"The last three are more difficult for the time being. You can start with the motive of committing the crime."

"Before, a few of us were biting each other and talking about the conflicts between each other and Wang Lihua, but this was only on the surface."

"No one else will know what is going on in secret."

"If the investigation results show that someone has a very strong motive for committing the crime, then the direction will come out."

Investigating the motive for committing a crime is a very important part of homicide investigation, and sometimes it often plays a decisive role.

The circumstances of each case are different. Some can identify suspects based on on-site clues, while others cannot.

If the suspect can be identified first and evidence produced, then the motive for the crime will be simple and can be discovered directly through interrogation.

If the suspect cannot be identified, reverse the process and first investigate the motive.

The motive for the crime is established, and the suspect emerges.

Motivation, behavior, results.

The circumstances of this case are very suitable for working backward from the starting point and figuring out the motive first.

Zhou Yebin nodded: "There's no problem with the idea."

"Zhuo Yun, take someone with you and check carefully. If you find anything, call us immediately."

Zhuo Yun: "Yes, Team Zhou."

Chen Yi: "Take Sister Jiang and check if Wang Lihua has a computer at home."

"Even if you are browsing search history, you can't fall behind."

"Also, I checked my cell phone by the way."

Zhuo Yun: "Okay, I understand."

A person's mobile phone and computer are very private, and if the contents are published, it is very likely that the public will die, such as men's search records and women's group chat records.

There is no way, this is a process that people who die abnormally or are suspected of dying abnormally must go through.

After Zhuo Yun left, Chen Yi said: "Team Zhou, let me call Shu Yu."

Zhou Yebin: "Okay, then I'll go in first."

Chen Yi: "Yeah."

On the other side, Fang Shuyu, who was still conducting a comprehensive autopsy, felt tired.

So far, no other suspicious clues have been found, except for the dark red spots around the lips of the deceased, which are very similar to those left by mechanical suffocation caused by external force.

At this time, the cell phone rang.

Fang Shuyu looked back at the cell phone placed on the table, then took off his gloves to connect it and clicked on the speakerphone.

"Chen Yi."

Chen Yi: "Shuyu, do you have any new discoveries?"

Fang Shuyu took off the mask and said: "Not yet. Mechanical suffocation is certain. The question is how to cause suffocation."

Chen Yi: "He has basic nasal diseases, and he also takes diazepam drugs."

Fang Shuyu: "Is there any connection between the two? Do you want to say apnea during sleep?"

Chen Yi: "This is one of the possibilities."

"Shu Yu, what do you think of the dark red spots around the deceased's mouth and nose?"

Fang Shuyu: "It's very similar to mechanical asphyxia caused by external force."

"Since you said that only that girl had contact with the deceased, we should investigate it carefully."

She didn't care about any of this before and was only responsible for autopsies.

Facing Chen Yi, it became much harder to speak.

Chen Yi: "It is unlikely to kill a person through suffocation in five minutes."

"Unless, use tools."

Fang Shuyu: "What tool?"

Chen Yi was slightly silent and said, "It's hard to say yet, but there must be a way."

"Shu Yu, have you checked the gastric contents of the deceased now?"

Fang Shuyu: "No, what's wrong?"

Chen Yi: "I want to know if he has drank that bottle of mineral water."

Fang Shuyu: "Is this important?"

Chen Yi: "It's very important."

Fang Shuyu paused for a while and said, "It's hard to check mineral water. After all, it's water, not food."

Chen Yi: "That is not ordinary water. It contains many minerals that other water does not have. You can go to the technical department to see the specific ingredients."

"If it's difficult to check the stomach, start with the oral cavity and esophagus."

"Ion detection, okay?"

Except for ionic crystals, there are no ions in solid matter.

If a large amount of mineral residues can be found in the oral esophagus, it means that Wang Lihua drank that bottle of water.

On the contrary, it means I haven’t drunk it.

Fang Shuyu: "Give me an hour."

Chen Yi: "Okay, thank you for your hard work."
