According to Yu Yang's investigation, the identity of the second deceased has been roughly investigated.

It's also a bit of a coincidence, this deceased, like Tao Zhipeng, who was killed before, both of them have the surname Tao, and I don't know if they have some kind of kinship.

This point has not been clearly reported for the time being, because this middle-aged man named Tao Ji, he only lives here temporarily, his hometown is not in the city, and no one in the family knows who else is, if it weren't for the person who called the police to see him before, he can't even determine his identity now.

Although the name of the deceased is already known, according to the search of the neighborhood committee, this Taoji's hometown is not in the city, although there are several relatives in the city, but the specific location is not known for the time being, and it will take a little time to find it.

Of course, in addition to the identity, in fact, they are not completely without any progress, at least they have found something in the surrounding police stations.

"This Tao Ji wasn't a good thing before, a frequent visitor to the police station. Yu Yang opened the notebook in his hand and said to Ding Fan: "I heard that this kid didn't live here before, it seems that he came here to escape the disaster because he caused trouble in his hometown, but this kid is not a fuel-efficient lamp, and he didn't cause trouble here." He caused trouble outside for three days, even if he was a new police officer, the first person he knew must be this kid. ”

Looking at the situation at the scene, coupled with the reputation of this Tao Ji outside, it is clear that vendetta is more likely.

This can also completely echo the situation at the scene, if it weren't for the vendetta, I don't think it would have been so bloody!

"There are traces of a fight at the scene, have you asked the surrounding residents?" According to the traces around the scene, it is obvious that the deceased had fought with people before his death, especially Ding Fan found a long mark on the wall, if there is no mistake in judgment, this should be the trace left by a sharp weapon.

Since there is a fight now, it is impossible to have no sound at all.

When there is a sound, isn't there anyone who is curious to go out and take a look?

There should be eyewitnesses!

It is said that Ding Fan's speculations are completely possible, Yu Yang also thought about this problem at first, but after knocking on the door for a long time, he found that there was no one living here at all.

"Don't mention it, I have also thought about this problem, the neighborhood committee said that recently, there is no one living here at all. Yu Yang looked sad, stretched out his hand and patted his forehead, and said helplessly: "This is the old city, its location belongs to a depression, when it comes to the rainy season, it will be difficult to drain the rainwater here, the city has arranged people to deal with the situation here this year, the surrounding residents have temporarily moved away, and there are not many people living here, when the crime happened here yesterday, there was no one in the whole alley, where to find witnesses?"

Ding Fan hasn't been in Bincheng for a long time, and he really hasn't heard of this problem, but he just thinks that since there is a sound of fighting, someone here will definitely come out to take a look.

I can't think of another reason for this, this Tao Ji is likely to be the only resident in the entire alley, except for him, no one will appear here, and it is precisely because of this that the murderer will choose to do it here.

"I see. Ding Fan glanced at the location of the alley, looked at the alley, and suddenly figured out a question that he had not been able to understand before, nodded and said: "I was still thinking about why the murderer chose to do it here, it is said that in this small alley, the murderer will inevitably choose to use the fastest speed to kill the deceased, otherwise once there is a sound, someone will inevitably come out, and the murderer's murder plan will be affected, besides, such a small alley is not the best place to kill." Now it seems that this person must have known before that during this time, no one would appear in this small alley, so he was able to appear here in a grand manner and choose a very dangerous way to kill. ”

A dangerous way to kill?

Yu Yang didn't understand what Ding Fan meant by the dangerous way of killing.

In his opinion, murder is a simple and direct crime, what is the danger in it?

And Ding Fan seemed to know that he didn't understand what he meant, so he said: " The whole alley is more than 50 meters long, not to mention the night, even during the day, the light here is not very bright, killing people in such a place, the best way is to attack suddenly, often the best results can be obtained, and even the cost is the smallest one, just like a previous homicide case, the murderer suddenly attacked from behind, after a blow was successful, the deceased was pressed to the ground, and the blunt object in the hand hit the person to death several times in a row, which is the least expensive way to kill. ”

As soon as Ding Fan explained, Yu Yang immediately understood the secret, his eyes were full of admiration for him, and he was like a god, he really didn't know before, it turned out that there were so many subdivisions in this murder case.

It's just that when Ding Fan said this, he suddenly stopped, as if he thought of something, and the whole person froze in place like a stone statue, looking at everything around him with blank eyes, as if he had formed a picture in his mind.

Ding Fan thought for a long time, and suddenly his eyes lit up, and he turned to look at Yu Yang's eyes wide, and said with a strange expression: "Do you think, is it possible that these two cases were done by the same person?"

The same person?

That's a serial murder case!

It is said that such serial murders have not happened before, and the most famous is the Obo case.

Who in the entire Northeast doesn't know the modus operandi of this murderous madman!

Even in order to study his murder methods and the logic of killing, the archives are full of two boxes of case files about him, but this two cases seem to be very different from Obo's previous murder cases.

For example, although Obo kills people without logic, it is basically to see who is not pleasing to the eye, and kills people on the spot, and there is basically no distinction between men and women in the choice of killing, but there is a habit that he has almost every time he kills, that is, the time when he kills must be chosen at night, and it must be in a sparsely populated place, so as to ensure that after the killing, he can leave quickly and disappear without a trace.

However, looking at these two cases, after analysis, it seems that there is no special connection.

If you want to talk about the similarity, it seems that the people who were killed these two times, both men, died on the way home, and disappeared without a trace after killing people, and they seem to be very familiar with the road here.

But is this also a connection?

It seems that many homicide cases have such characteristics, and the motive basically covers most of the killing factors such as robbery and murder, vendetta and so on, and it seems a bit far-fetched to say that it is a serial murder case, right?

In fact, from the beginning, Ding Fan didn't think that there was any connection between the two cases, but he just thought that the two murderers were a little similar in terms of the time they chose.

The second is that the murder weapons used by the two murderers are also very different, and even when they commit the crime, there is a big gap in the methods, and the things presented at the two murder scenes are completely different states, and it is not like a case completed by one person at all.

If it is a person who commits the crime, it is impossible for the counter-investigation before and after to be so big.

In fact, Ding Fan also inadvertently thought of a point, that is, the final death location of the two deceased, the scene of the killing itself is not far away, and the location of the death is also in the alley, is there really no connection between these things?

Of course, what made Ding Fan doubt the most was actually what these two people experienced before they died.

The first deceased, Tao Zhipeng, was attacked by someone in the back of the head, and it is said that he was in the back of the head, and about three blows were completely enough to kill.

However, on his corpse, the wound that appeared was obviously hit more than three times by the murderer, and the entire back of the head was punched out with a huge hole, which obviously had a reason to vent his anger.

In addition, the big man also said it before, and obviously heard someone say something like revenge, it is obvious that Tao Zhipeng's death was because an enemy came to the door and killed people in order to take revenge.

As for Tao Ji, although the autopsy did not produce results, Ding Fan had also seen something before, and with the situation at the scene, he could judge some problems to some extent.

If I guessed correctly, this Tao Ji also died in a vendetta.

The blood on the ground is only one of the proofs, and the knife wounds on his body are completely telling.

If both of them died in vendettas, is that a common denominator?

Even if the murder method is a little different, in fact, it is not necessarily that the murder weapon carried by the murderer has changed, who can guarantee that the knife is really brought by the murderer?

"What do you see here?" Ding Fan walked to the position by the wall, stretched out his hand and pointed to the blood stains on the ground, took a tape measure in his hand, squatted on the ground and measured it, and said, "What do you look like in this position?"

The location where Ding Fan stretched out his hand should be a splattered blood stain, surrounded by a dark red, except for the position of the root of the wall, there seems to be a fault.

The appearance of this position did make Yu Yang think of something, but it was a little vague, and he didn't know if he was thinking right for a while, and it was very difficult to even describe his thoughts in detail, and sweat flowed out of his anxious face.

"Isn't it as if the things that were originally placed here have been taken away?" Ding Fan reached out and took a stone, placed it on top of this empty seat, stretched out his hand and swiped it in the air, then took the stone away, pointed to the position of the empty seal on the ground and said, "See?" There was originally something here, when the two were fighting, blood splattered in this position, and blood stains were left around, and the original thing in this location was also stained with a lot of blood, but after the murderer killed, this thing was taken away, so there was a blank layer here. ”

Ding Fan said this, if Yu Yang didn't understand, he wouldn't have to mix in the criminal police team: "I understand, the murder weapon, what was originally placed here was the murder weapon, in fact, the murderer originally wanted to use this thing, but something happened in the middle, the murder weapon fell out of his hand and fell in this position, and he had to replace a murder weapon to use, so the murderers in the two cases, the murder weapons used are actually the same, plus the location of the crime, they are all in the alley, and the deceased are all male...... It's really possible that it's the same murderer!"

Actually, Ding Fan has some other thoughts about this time.

It's these two deceased, since they are both surnamed Tao, could it be that there is some relationship between these two people?

Of course, this point itself also has a certain coincidence, so Ding Fan didn't say anything about it, but just mentioned his thoughts to Yu Yang, and asked him to take a look at it by the way when he investigated, hoping to help this case a little.
