A killer who was invited in, and who knew exactly what he wanted. This person is not a doctor, Wu Ziyu said when he examined the corpse that the hollow on the top of the deceased's head is not so easy to cause, but it is made little by little.

Near the wound, some burn marks were found, which should have been used with an ordinary electric drill. The man did not injure the deceased's skull, but he stuffed a note that could not be seen from the hole, let alone thought that it could be done here. The murderer only admits the guilt of the deceased, but not everyone deserves death, just like the person in front of him, was also killed because of this?

It's not good to steal things, but it really deserves to be killed like this, isn't that too cruel?

This time, the scene was relatively clean because the deceased himself did not want to leave any traces.

So who is this man? How do you know where the deceased lives and why the deceased opened the door for him?

Looking at it this way, it seems that the murderer should be someone who knows You Tingyue, otherwise he just made some excuse.

In short, the murderer must have known about the circumstances of the deceased, and was very sure that the deceased was at home at this time. The deceased was a cleaner at a department store, and he usually went to work at six o'clock in the morning, so he came here during this time.

The body of the deceased was hung up, and the rope passed through this hole, it shouldn't have been the beauty who heard the voice, right?

Ling Xiyan closed the door of the room and asked them to make some noise inside the room.

When I opened the door, I found that the sound was very loud, but the sound I heard outside didn't seem to be so loud.

The sound insulation of this room is relatively good, and it seems that there is a problem, but no one knows the reason.

Yang Yao found a not very complete fingerprint in the position where the deceased was hanging, but it was better than nothing. In this way, it can be regarded as some discoveries, Ling Xiyan feels that it is still necessary to improve the file of fingerprints, so that it can be more convenient to find the suspect.

The biggest problem in the community is that monitoring is useless, so I don't know who is coming at this time.

It's an older place, and there are no security guards here, let alone anyone else who can see the killer.

Judging from what is available now, the murderer should be a person with brains and access to information.

It is likely that in the hands of the murderer, there is a more detailed information about the person with a criminal record. He probably knew what was going on with these people, where they lived, what the phone number was.

It's just such top-secret information, if it weren't for the police, it would be difficult for outsiders to know, how could this person know?

Even if an outsider knows these things, it is impossible to be so detailed, and even have an address and phone number.

The results of the autopsy can only be known when you see them, and I don't know if there are these in the deceased's mind.

What does it mean to write a crime and put it in your head? Ling Xiyan felt that he had to check out the others.

Yang Xiao watched the scene and felt a little embarrassed: "This person is actually very hard-working and wants to live a good life." ”

Everyone who has gone through this wants to come out, live a good life, and spend a lifetime peacefully. There is no need for them to take risks, and they don't need anything more.

How did such a group of people provoke this cynical murderer? Do you have to do that?

Packing up his things, Yang Yao also felt that this person was just trying to live well.

But some people didn't give her this chance, and in the end, they did it to her.

Judging from the photos, You Tingyue in the past was also very good, and her appearance was a relatively sweet type.

But after staying in there for a few years, no matter how good-looking a girl is, there will be some changes. Not to mention, after coming out, You Tingyue didn't know what else she could do, and finally chose this profession, which was not paid much attention to and did not have too many requirements.

After going back, Ling Xiyan didn't go to Wu Ziyu, and waited for Wu Ziyu to bring her autopsy report.

Now Ling Xiyan, wholeheartedly, put his own investigation at the source of these materials.

In other words, any police officer who has this authority to investigate the circumstances of the deceased is questionable.

Yang Xiao put the information of the two people together: "They were both released from prison a year ago, Xiyan, do you think this has anything to do with it?" Why do it now? It's been a year since I got out of prison, is it a little too late to do it now? ”

If according to their thoughts, the murderer is looking for these people who have been released from prison, but why not just released from prison? Such a person, as long as he goes to the prison gate, can be seen at any time, in fact, it is better to lock his target. As long as you find a way to be a black car driver, you will be able to know where the deceased lived, in fact, it is simpler, everything is easier to investigate, and it is easier to hide.

People who were released from prison a year ago, the list is not easy to obtain, not to mention, for such a long time, who knows if the person is still there?

The murderer did not choose, those who had just been released from prison, but chose a year ago, what does a year mean?

Wait a year and then kill these people, so what was the original purpose of killing these people?

A lot of problems have accumulated together for a while, and Ling Xiyan also has a feeling of being a little big.

If it was what they had envisioned in the beginning, then why did this person choose someone who had been out of prison for a year? Yang Xiao felt very curious, of course they were all so curious, a year is not a short time.

The crowd began to investigate, and some of the police officers might know about it.

Because although these are encrypted, they are not top secret, and not everyone can know about them.

It's not easy to investigate, it's not easy to obtain, but it's not very difficult, and you can do it with a password.

And these materials, if they are circulated, have a great impact, so they need to investigate carefully.

Recently, since a year ago, the people who have seen these things are all kinds of people. was released, probably because he behaved very well in it, and it was impossible for people to know about these things at first.

Therefore, it is only after being released from prison that these materials will be updated accordingly, so it must be known later.

So I investigated the date of the release of these two men, and after that date, investigated the people who had seen it.

These materials, except for the updated personnel, or some follow-up investigators, will basically not be read.

After all, no one will be idle with these materials, and they will look through them here, unless they involve a case.
