They finally questioned a few people who usually took notes, but none of them were suspicious. If someone has seen it, the traces will definitely be left, especially these browsing records, which will be recorded.

Those who have seen these people are naturally easy to find, and they have all been asked one by one.

Ling Xiyan's investigation was interrupted here, without any results and no progress.

As the day's investigation ended, Wu Ziyu was also waiting to give them an autopsy result.

"You Tingyue and Wang Jian died in the same way, they were strangled and hanged up."

Wu Ziyu reported the autopsy to them: "The same note, you can look at the contents of the note." You don't have to kill someone if you steal, right? I really don't understand what this person is thinking, and even if he deserves it, he won't do it. ”

Pursing her lips, Wu Ziyu was a little difficult: "The girl's bone age test is only twenty-two years old. ”

"She shouldn't have had a boyfriend before, let alone married, which is actually a pity."

It is really embarrassing that a person who is already planning to start over is so robbed of the opportunity.

Yang Xiao waved his hand at Wu Ziyu: "It's a pity that you don't get so excited first, but there is no way." ”

"We should find the murderer quickly and solve this case. Otherwise, there will be more people who will die because of this. Xiyan, where do you think we should start now? ”

Zheng Yiteng looked at Ling Xiyan a little strangely: "Xiyan, what's wrong with you?" Do you feel uncomfortable? ”

At the beginning of this case, Ling Xiyan was relatively silent, and many times he didn't speak.

Just silently, looking at the photos of the crime scene, or looking at the autopsy report and other materials.

Ling Xiyan shook his head: "I'm fine, I just have some feelings, I think we should still start with the first two points." Although there were some problems with our considerations at the beginning, the beginning was the most intuitive. ”

"And I think these two scenarios are also the most appropriate, so let's start here."

Yang Xiao also unifies this idea, and it is easier to start here.

Now they can't be sure what kind of person they are looking for, they can only guess.

These two possibilities may be the closest to the truth now, so we have to look for someone who was released from prison a year ago.

Since this point in time was so important a year ago, and the killing was also related to this, then something must have happened a year ago. This matter is the crux of all this case, and they have to figure it out.

Something a year ago, perhaps someone's departure, stimulated some of the murderer's nerves.

It may also be because the murderer himself spent a long time in prison.

After coming out, the murderer may feel that some people need to be punished, and these people should die.

Anyway, it's not an ordinary situation, no matter how you look at it, this person's emotions are a little too excited.

Ling Xiyan also felt that the person they were looking for was definitely not easy to find, and there was a very serious emotion in this person's heart. This kind of emotion may only be done to these people now, but it may not be necessary in the future. And for a long time, it is very bad for everyone, especially for those who they speculate, the possible victims, even more so.

Everyone continued to investigate these people who had been released from prison, since the only common denominator was this. The two deceased were of different genders, and they were in different situations, with different jobs and different living environments.

The only thing that may be the same is that these two people have criminal records, and they both came out a year ago.

There is nothing else in common with this squeak, and this year, it is definitely worth thinking about.

So they started to investigate, some of the prisoners who came out a year ago, of course, this is definitely not a small number.

Such an investigation may find a lot of situations that echo their speculations at first, but they are actually not ideal. And this person who has not revealed his other characteristics for a long time makes them feel that finding him is like looking for a needle in a haystack.

But the good thing this time is that there are still some blood stains behind the fingerprints they have identified.

The bloodstains exist in the fingernails of the deceased, not the deceased themselves, and You Tingyue must have struggled.

Then You Tingyue is likely to have left some traces of the deceased on her body.

These traces are likely to be the key to finding the dead, and they certainly need to be well preserved.

It's just that the current investigation results are not very ideal, and they still can't find this person.

You Tingyue's body, on the third day of discovery, all the messages in the police station were encrypted. In other words, if something is leaked out by chance, it will never happen in the future.

After all, Li Li has not been watching this system, so it is not very clear whether it has been invaded.

Otherwise, with Li Li's ability, he may know why these messages can be leaked.

Under Hua Shu's plea, all systems of the entire police station were re-encrypted and programs were written.

Li Li is the one who re-encrypted, and Li Li has also talked to some people in the prison a little.

Some people are very capable, and they know very well what methods they can use to resist all attacks. These levels must be very perfect, otherwise a variety of firewalls will be required.

Li Li completed such a procedure by herself, and it also took three days.

Writing programs is not very easy, especially at this time, Li Li is the only one to do this.

The people in the technical department also said that they had never seen this program written by Li Li before.

Not only is it very protective, but it is also able to catch and track, which is really amazing.

Many people still want to meet Li Li, and even worship him as a teacher, but Li Li refused, he has been busy for three whole days, how is it possible, there will be time to meet these people? What's more, Li Li doesn't think that he is so amazing.

There are some who have been locked up, and there are some who have not been discovered, in this world, there are actually many geniuses.

It's just that even if they are geniuses, they don't necessarily need to be known by everyone, they may just be silently giving.
