Hu Dekai's case can be regarded as a conclusion in the end, but in view of Pengcheng's current troubles, Hu Dekai's case is simply a trivial matter.

At least when Hu Dekai killed someone, he didn't have any concept of killing, and he didn't even know that he had killed someone, but when he was investigating, he still had a certain direction to look for.

Because he is not a professional killer, killing people is still a relatively unfamiliar job for him after all, but he will make a lot of designs for the layout of the scene.

In this way, he will always leave too many traces at the scene, and following these traces, it is not difficult to find some direction of investigation, and even what he is pursuing.

On the contrary, the people Ding Fan is facing now are really a little difficult.

The method of killing was clean and neat, and there was hardly a trace of it at the scene, and it was not known what his purpose was.

What can be seen at the moment is that this murderer has a certain show-off mentality in committing the crime.

When others kill people, they are basically very hidden, and they don't even want anyone to find out that they have killed someone, and after killing someone, they can't wait to dispose of the corpse cleanly, and they will never let others see the corpse.

On the contrary, it was the murderer this time, and he even had to notify Ding Fan in advance before the killing, as if he had made a special trip to call him over to have a look.

This made Ding Fan a little uncomfortable, and at the same time, he also remembered that some children like to do some unexpected things around their parents, and even these things are a bit out of line, and their purpose is actually very simple to attract the attention of parents.

After hanging up the phone, Ding Fan finally learned some new information from Qin Lu's mouth, according to her examination report, the deceased had taken a bath before his death, and there was a bathroom in the next room.

However, after identification, these blood stains were not venous blood, but women's menstrual blood, and the deceased was just in the stage of menstrual period before death.

This is also the reason why Ding Fan saw blood stains on the ground outside the window at that time.

After listening to Qin Lu's words, Ding Fan suddenly thought of a possibility.

When he arrived at the scene, he did not find the body of the deceased in the living room, and at first he just thought that his vision was blocked, so he did not see it.

But in fact, there is another possibility.

That is, when Ding Fan arrived at the scene, there was indeed no body of the deceased in the living room, because the body was still in the bathroom at that time.

The body that Ding Fan saw was actually the body found in the living room after the police arrived.

And the murderer never left the scene from the beginning, not that he didn't have time to leave, but he didn't think about leaving at all.

After Ding Fan found the body, the first choice was to call the police and notify the police to rush to the scene, while he himself chose to withdraw from the scene to minimize the biological traces he left at the scene.

But it was precisely because of his idea that he just gave the murderer a chance.

He took advantage of the time when Ding Fan left the yard to change the position of the body, and then hid in a dark corner, waiting for the police to arrive.

After the police arrived at the scene, there were many police officers around, he was wearing a police uniform, and he walked out of the courtyard in a grand manner.

This small action will not arouse Ding Fan's suspicion at all, after all, this itself belongs to the normal process.

While taking away these things, he took advantage of the fact that the people of the criminal police team had not yet arrived at the scene, went to the neighborhood committee as soon as possible, and used his police uniform to force the director of the neighborhood committee to transfer all the relevant information of the deceased, and one step ahead of the people of the criminal police team to transfer the things, perhaps they had been destroyed at this time.

But this is not over, after leaving, he took the mobile phone apart, and made a little trick inside the mobile phone, taking advantage of the lack of security in the police station, hid the mobile phone in the interrogation room.

There should have been some temporary adjustments before, blocking a large number of messages, as well as phone calls, until the next day, when a text message came again.

The whole plan is perfect, it seems that all the people in the entire police station are being played around, no one can see his flaws, and even Ding Fan has become a plaything in his hands.

Fortunately, it's not too late for Ding Fan to figure it out now, many things have actually been figured out, and the things that can be investigated later have become much clearer.

For example, the relationship between the deceased and the murderer is the direction of an investigation, although this investigation may be difficult, but it is more or less a direction.

The second is the matter of Gu Yue back then, where did it leak out, Ding Fan needs to find someone to investigate this matter properly, after all, there are not many people who know about the matter between Ding Fan and Gu Yue back then, and it can even be said that there are very few.

But this matter, Ding Fan is inconvenient to investigate through the relationship of the police station, so he can only hand over the matter to the old smoking gun in the northeast to help.

can take out this matter to threaten Ding Fan, thinking that this person knows a little bit about him.

In addition, this mysterious person seems to know very well about the internal investigation process of the police, from the murder at the beginning to the evacuation scene later, he has done it very smoothly, smoothly, obviously he is not an ordinary understanding of the process of on-site investigation.

At this point, Ding Fan needs to find someone to investigate, but the scope of this investigation will not be aimed at all the current police officers, for his own people, he has never been easy to doubt, this is his style of work, and he has always maintained trust in his own people.

But those police officers who were finally fired because of some problems, he needs to make some preparations, and if this murderer was really fired from the police station, then this person is likely to have been fired from the local police station.

Although the process of investigating cases will be similar to most police stations, there will be some slight differences in each place.

And as long as there is a slight error in the whole case, it is very likely to lead to the failure of the whole plan.

When Ding Fan thought about this, he really thought about it for a long time, took his mobile phone and thought about it for a long time, but finally did not call the phone, but wrote a note, and then went to the hospital, bought some medicine, and secretly stuffed the note into Aili's pocket.

This note will definitely fall into Zhuo Fatzi's hand in the end, and through his hand, the note will be passed to the place where it should go.

At present, in the entire Pengcheng, Ding Fan has to be cautious, here, there are not many people who can make him trust, but there are probably a lot of people who can monitor him.

At least until now, Ding Fan has not found the mysterious person who is spying on him, where exactly will he be staring at him.

For this reason, he must be cautious, keep a certain distance from all the people he has known before, and at the same time try to pass on what he doubts.

After a busy day's work, seeing that the sky was gradually getting dark, Ding Fan took advantage of people's inattention and hid in the dilapidated housing area again.

He ignored the text messages that popped up from time to time throughout the day.

I returned to the place where I had been staying, checked the door, and then climbed over the side wall and went straight inside.

But when he walked to the door, Ding Fan suddenly frowned.

He touched the edge of the doorway, then put the bag in his hand at the door, and took out a dagger from the position of his waist.

Just as he was about to make a move, the door of the house was suddenly pulled open from the inside, and Ding Fan took the knife in his hand, rushed into the room, and pressed the knife in his hand on the neck of the person at the door.

"It's me!"

In fact, the person at the door just didn't speak, Ding Fan could see who was at the door, and the knife in his hand had already been retracted, otherwise the knife just now might have cut his throat.

"Didn't you go back to see your sister?" Ding Fan knew that the person in front of him was Lu Sheng, but the knife in his hand did not think about withdrawing, he still pressed it on Lu Sheng's throat, and said in a cold voice: "You shouldn't come back, I did save you before, but I just wanted to ask something out of your mouth, now I know what I want to know, the pill you want is also given to you, you and I don't owe each other, you don't need to come back!"

Lu Sheng was forced into a corner by Ding Fan's murderous aura, almost unable to retreat, and the hairs on his body stood up one by one.

He could fully feel that Ding Fan at this time was basically two people from the morning, from warm to murderous, it seemed that it was just a blink of an eye.

He didn't understand why, Ding Fan would have such a big change in a short period of time, but his return was also thoughtful: "I...... I still don't want to kill people, and I don't want to be like those people, to become a brute without humanity, but my sister's illness needs that kind of medicine, so I want to cooperate with you. ”

"Cooperate with me?" Ding Fan tilted his head, glanced at Lu Sheng a little curiously, and said with a sneer: "You can cooperate if you want to, but you didn't imagine, why should I cooperate with you?"

"Just because I can give you that pill today doesn't mean I'll give it to you next time, and I don't think that cooperating with you will be of greater benefit to me!"

Lu Sheng seemed to have thought about this question on the way back, and now that he heard Ding Fan ask, he could only swallow hard, took out a piece of paper from his pocket and said: " I've been involved in this game for more than a month, and some of them, I've seen them before, and here's their information, I don't think you're involved for anything, it's very likely that some of the people on this are similar, what you want is not what is in the bag at all, but what handle is in the hands of the person behind it, so it will be more secure to cooperate with you!"

Lu Sheng's kid looks very simple, but now it seems that he is not simple, and his brain is still quite clear.

As for what he had in his hand, Ding Fan was really interested.

And he has a fatal weakness, he has a sister who needs to be taken care of, which makes it difficult for him to do things out of the ordinary, and the risk of failure is simply not acceptable to him.

And at this time, for Ding Fan, it is really a time when there is a shortage of manpower.

The mysterious man has never shown up, and has been hiding in the dark and planning everything, causing Ding Fan to be extremely passive.

He wants to turn passive into active, and he just needs some help, and this Lu Shengzhi is also a good help, if the list he has in hand is useful, things may be easier.
