No matter what happens in the future, at least the current case has finally seen the light of day.

From the beginning to the end of the case, Ding Fan has roughly found the cause.

If you are not mistaken, the murderer of this serial murder case should be the relatives of a deceased person in the address scientific expedition team that year.

Judging from the time, the age of this murderer should be not young, after all, the ages of these deceased are all here, and in the past ten years, I am afraid he has also done a lot of investigations.

Recently, during the period when he committed the crime, maybe his movements were not very big, and he did not have contact with anyone.

But a few years forward, I think this person still has a lot of actions, otherwise his investigation would not be so accurate.

Ding Fan's investigation during this period of time, although it was also very accurate, but this was because of the promotion of the police station, and all aspects of society gave great help, so the boarding team of the year was found, and I am afraid that another person does not have this ability.

Therefore, if you want to investigate this matter, in addition to the original geological exploration team, you also need to find a way to investigate whether anyone has done any investigation in a neighborhood committee or something.

After all, although many of these deceased people no longer live in their original places, it is still up to these neighborhood committees in the community to decide where these people's hukou will be moved.

I'm afraid that this incident has passed for too long, and the original neighborhood committee officials may not remember these things.

However, even if there is little hope, you always have to ask someone to go over to investigate it, but this large-scale investigation is not something that Ding Fan can do alone, so on the way back, she also notified Meng Huan and asked her to arrange someone to investigate this direction immediately.

After running outside all day, Ding Fan has not even drunk a sip of water, let alone eating, and his body is almost at the limit until now.

I found a small shop on the side of the road, simply ordered a little food, sat at the door, and looked at all kinds of people around me while eating, and accidentally found that the people sitting outside to eat seemed to be paying attention to the TV.

Ding Fan subconsciously turned his body and also glanced at the TV, an advertisement was playing on the TV, it was not something special, but this advertisement attracted the attention of many people.

This is a bit puzzling to Ding Fan, watching the news and watching TV series can be understood, can people still be so interested in an advertisement now?

Ding Fan couldn't figure it out for a while, but it didn't take long to watch the TV and he understood where the root cause was.

In fact, the advertisements on TV are not shown casually, but are specially sorted, and this segment of the advertisement is the most eye-catching at the moment before the TV series is about to start.

It's not because of how good the product is, but everyone knows that after this advertisement, the TV series begins.

The means are not very clever methods, basically everyone can see it, but the effect is still very good, at least the audience is really large.

Even though everyone could see it, everyone was still sitting obediently next to the TV when this advertisement appeared.

Wu Gong is a smart person, there are some things that don't need to be said a lot, as long as he is a little bit, he knows what to do about this matter, and his ability to do things, Ding Fan still recognizes it very much.

After explaining everything clearly, Ding Fan finally finished his meal with confidence, wiped his mouth and glanced at the TV series that was still playing on TV, laughed helplessly, and turned around to go back to the guest house.

But when I returned to the guest house today, the room was really lively, not only Qin Lu and Meng Huan were inside, but even Li Meisi and Wen Yao were there.

Li Meisi is here, Ding Fan can barely understand, after all, she is a person who loves to join in the fun, where there are many people, there must be her, if she is missing, it would be a little strange.

But what is the situation with Wen Yao?

The last time they met, Wen Yao was trembling with anger, and ran out with a blushing face, Ding Fan thought that the two would not meet in the future, and even thought that the book in his hand looked very valuable, and he didn't know how to send it back.

Well, now that people have come to the door themselves, but this time seems to be a little inappropriate!

Anyway, Ding Fan stood at the door and watched for a long time, and he didn't even know what to say, this room seemed to him to be like hell on earth, no different from the hell map drawn in the book.

"Master, you're back, I'll be waiting for you when you come in!"

Li Meisi felt like a nobody, and when she saw Ding Fan coming back, she came up to say hello quite warmly.

Won't she look at the people in this room, and where he stays?

If you go in at this time, you will be eaten alive by life if you can't keep it.

Four women are sitting in the room, which is enough for a table of mahjong, and it is definitely not the best choice to go in at this time.

"Come in, we've made it clear!" Qin Lu sat on the sofa in the middle, seeing Ding Fan's embarrassed face, he suddenly wanted to laugh a little, who would have thought that when he saw a group of women, who would have thought that he would also have a retreating side?

However, after Qin Lu said this, Ding Fan was indeed relieved in his heart.

Looking at the situation between these women, it seems that there has not been any vicious battle before, maybe it has really been made clear at this time.

The trembling Ding Fan cautiously walked into the room, glanced at the furniture inside, the position was quite neat, and he had not moved the position before, the imaginary battle should not have happened, which invisibly relieved Ding Fan.

"You ...... this"

"Master, that's what I mean, I'm causing you trouble today, so I'll find everyone over and explain it to everyone!"

Li Meisi didn't find anything to do with Ding Fan today, since she saw Wen Yao before, she has been looking for trouble in the back, Qin Lu and Wen Yao were basically offended by her, but I didn't expect that this girl would also find out with her conscience.

"I understand the situation, don't blame her!" Qin Lu sat on the side and said calmly: "Don't you just want to learn something from you? Just teach her, I think this girl is also quite sincere, and it's not a secret that is not passed on, so she can't hide it!"

Qin Lu said this, Ding Fan immediately understood.

Li Meisi's conscience found out, and it was clear that she had no chance to grind hard with herself, so she could only find another backer.

It's no wonder that she explained everything that happened today to a few women, she wanted to find someone to help talk, and she was afraid that she would refuse!

"Where do I have this mind now!" Ding Fan sat on the side with a sullen face, glared at Li Meisi viciously with his eyes and said, "Now the case is not finished, I don't have time now!"

As soon as it came to the case, Li Meisi's eyes rolled and she glanced at Wen Yao beside her.

This little girl was really sensible, and immediately stood up, saying that it was not too early, and she wanted to go back early, Li Meisi also took the opportunity to send her, and the two left one after the other, and there were only three people left in the whole room: Ding Fan, Qin Lu and Meng Huan.

Now that the people who have nothing to do with the case are gone, it is much more convenient for Meng Huan to speak.

"Master, you didn't attend the afternoon meeting, I brought the materials back, help take a look!"

Meng Huan said this, Qin Lu was not idle, reached out and took out a file book from his bag, and handed it over: "This is the autopsy report of the deceased, I made it with great difficulty, but you didn't come back." ”

To be honest, Ding Fan was really anxious to see it before.

It's just that now he has something more anxious about, and he opened the book and glanced at it, basically everything he expected.

"The deceased's stomach is empty, I suspect that someone washed his stomach before!" Qin Lu saw that Ding Fan just glanced at the autopsy report and put it aside, afraid that he would not see what was in it, so he immediately explained: "In addition, I suspect that the murderer also used some drugs on the deceased before the killing, and the detailed drug test analysis will not come out until tomorrow at the earliest, and this time, the murderer used glue at one time, the position of the arm, and the mouth of the deceased were glued together, and the time of death was five days ago!"

Since the time of death has been determined, the corresponding Meng Huan should have been investigating the people that the deceased came into contact with in the last period of time.

Thinking about this, Meng Huan had already thought of it, and there was no need for Ding Fan to say anything.

However, Ding Fan is still a little curious about this medicine, he has not used medicine before, why did he use it for the deceased this time?

To be honest, Ding Fan was a little puzzled for a while.

But it's not just this one thing that I can't think of right now.

The Seven Deadly Sins should have seven different ways to die, and the murderer only used a simple way of killing from the beginning, only doing a little different action on the corpses of these people, until the recent intermittent time to shoot, some changes have occurred.

Apparently he didn't think of these things in the first place, but in the recent past, after his crime escalated, there has been a little change.

At least in the cause of March's death, it can be seen that the murderer has paid attention to the victim's death form at this time, and by the later Lu Dahe, the death method can be called weird.

When Ding Fan asked Lin Ziming today, Lin Ziming seemed to have thought of something, but he was not sure, but he just said that Lu Dahe was the most edible one in the whole team, and the food he brought at that time could be eaten by others for three or four days, and he would usually be empty in two days.

Ding Fan has always remembered this sentence, and Lu Dahe's final way of death was to put his hand in his mouth.

It looks like a person who reached out and dug something out of his mouth, and Qin Lu also said that there were traces of cleansing in the intestines of the deceased.

To sum up, the deceased, out of the seven deadly sins, should have died from gluttony.

So the murderer's crime this time is probably not just as simple as escalating the crime, at least there is a certain increase in the cost of the crime.

"There are a lot of things needed for stomach lavage!" Ding Fan lowered his head and frowned and pondered for a long time, then suddenly looked up at Qin Lu and asked, "If the murderer is only one person, can you complete this process with all the equipment?"

When Qin Lu heard this, he seemed to understand what Ding Fan meant, thought for a while and nodded: "A person can actually complete this process, but this process is a bit difficult, the premise is to ensure that the victim cannot resist, that is, to use anesthesia and other drugs on the deceased in advance, otherwise in the process of gastric lavage, the victim will also struggle and make a sound." ”

That's right, the murderer should have used an anesthetic on Lu Dahe, and then fixed the person, emptied the contents of the intestines, and then transported it back to the deceased's shop.

After this period of devastation, the deceased may not have much physical strength left, taking advantage of this time, the murderer is putting his hand in his mouth, the deceased's strength to struggle will not be very large, although Lu Dahe is relatively strong, but in the case of medicine in advance, he will not have the strength to resist.

It seems that in terms of medication, you can also do some research, after all, these things are not easy to buy.
