Chen Yi nodded: "So to speak." ”

"If he just wants to be close to Ding Zi, so he puts diazepam drugs in the wine, then he can directly hand the wine to Wang Lihua, and there is no need to go through Ding Zi."

"Everyone is sitting together, even if they are not next to them, just stand up and stretch out their hands, just like handing it to me and Jiang Fanlei, what are you doing so troublesomely."

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

"There are variables, and it is better to give them directly to Wang Lihua."

"He received the invitation notice on Tuesday, and he should have been preparing for the next few days, so why didn't he choose the safe way when he got to the door?"

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

"Give Ding Zi the words first...... Unless she knew in advance what Yuan Lihao wanted to do. ”

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

"That's 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?" ”

"Valium drugs are indeed difficult to poison people, even if Wang Lihua has underlying diseases."

"Could it be a chance to try your luck, it's best to kill it, and if you can't kill it, you'll talk about it next time?"

Zhou Yebin said: "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 the opportunity to do it. ”

"But to his surprise, the man died before he could do it, and God did him a favor?"

Zhuo Yun: "It seems to ...... If you don't rule out this possibility, it will be difficult. ”

"The problem now is that it is impossible to tell whether Wang Lihua died from his killing."

"If you don't even know this, how can you talk about investigation?"

Hearing this, Chen Yi spoke: "The autopsy is definitely not over yet, I'll call Shuyu later." ”

"The red spots around Wang Lihua's mouth and nose, I personally think there is a problem."

"Huh?" Zhuo Yun was surprised, "You still know about autopsies?" ”

Chen Yi nodded: "I understand a little, the books I read are more miscellaneous." ”

Zhuo Yun: "......"

After a moment of silence, he couldn't help but speak: "What else will you do, can you say it all at once, don't be like squeezing toothpaste." ”

Chen Yi: "Ability is used, not said. ”

"Do you know when the red spots appear? Mechanical asphyxia caused by external forces. ”

"Of course, this is theoretical."

Zhuo Yun wondered: "External force? No way, no one has the time to commit the crime. ”

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

"If Wang Lihua really died a normal death, we would have fulfilled our duties as a policeman."

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

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

Chen Yi snorted: "The elements of the murder include the motive for the crime, the means of committing the crime, the place where the crime was committed, and the time when the crime was committed. ”

"The last three are temporarily more difficult, so you can start with the motive for committing the crime."

"Before, several of us bit each other and told each other about the contradictions between each other and Wang Lihua, but this is only on the surface."

"Secrets, others will not know."

"If the results of the investigation show that someone's motive for committing the crime is very strong, then the direction is out."

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

The circumstances of each case are different, some can target the suspect according to the clues at the scene, and some cannot.

If the suspect can be locked up first and the evidence is presented, then the motive for the crime is simple, and it can be known directly through interrogation.

If the suspect cannot be locked, it is reversed and the motive for the crime is investigated first.

Once the motive for the crime was established, the suspect surfaced.

Motivation, behavior, results.

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

Zhou Yebin nodded: "The idea is no problem." ”

"Zhuo Yun, you take someone to it, check it carefully, and once you find it, call to notify you immediately."

Zhuo Yun: "Yes, Team Zhou." ”

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

"Even if you browse your search history, you can't leave it behind."

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

Zhuo Yun: "Okay, I see." ”

A person's mobile phone and computer are very private, and it is very likely that the content will die if it is published, such as a man's search record and a woman's group chat record.

No way, this is the process that people who die unnaturally or are suspected of dying unnaturally must go through.

After Zhuo Yun left, Chen Yi spoke: "Team Zhou, I'll call Shuyu." ”

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

Chen Yi: "Hmm. ”

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

So far, no other suspicious clues have been found, except for dark red spots around the deceased's lips, which resemble those left by mechanical asphyxiation caused by external forces.

At this time, the phone rings.

Fang Shuyu glanced back at the mobile phone on the desktop, then took off his gloves and turned it on, and clicked on the hands-free.

"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 underlying nasal diseases, and he also takes diazepam drugs. ”

Fang Shuyu: "Is there any connection between the two?" Do you want to say apnea in lethargy? ”

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

"Shuyu, what do you think about the dark red spots around the deceased's mouth and nose?"

Fang Shuyu: "It's very similar to mechanical suffocation caused by external forces. ”

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

She didn't care about any of this before, she was only responsible for the autopsy.

Facing Chen Yi, it was much more difficult to speak.

Chen Yi: "It is unlikely that a person can be killed by suffocation in five minutes. ”

"Unless, utilize tools."

Fang Shuyu: "What tool?" ”

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

"Shuyu, have you checked the deceased's stomach dissolution now?"

Fang Shuyu: "No, what's wrong?" ”

Chen Yi: "I wonder if he ever 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, "Mineral water is not easy to check, after all, it is water, not food." ”

Chen Yi: "It's not ordinary water, it contains a lot of minerals that other water doesn't have, and you can go to the technical department to see the specific composition." ”

"If it's hard to check in the stomach, start with the oral esophagus."

"Ion detection, is that okay?"

There are no ions in the solid state except for ionic crystals.

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

On the contrary, it is that I have never drunk it.

Fang Shuyu: "Give me an hour." ”

Chen Yi: "Okay, hard work. ”
