The professional quality of the male protagonist

If the murderer is not the couple, then there is only one possibility, that is, the murderer killed someone after they left and hid things in their room.

Ye Kai and the others proposed to investigate the people around them immediately. The method of checking DNA that was proposed before has now become a top priority. The best way is to conduct a series of investigations on the people around them, and then use DNA to find the murderer.

While doing this may take some time, it's the most efficient thing to do right now.

They had looked for some related clues before, but in fact they were not of much use.

Li Yancheng did not fully agree with Ye Kai's approach, but he did not refute it either.

It would be a good thing if the evidence could be used to directly prove who the murderer was, but Li Yancheng always felt that something was wrong, and this feeling had been there since the second Li Yancheng walked into Renrenzheng's house.

The violation is not just the situation after the destruction of the witness's home. There are many other violations. For example, the murderer's intention to put the blood-stained clothes in the couple's home is very strange.

If the purpose of the other party was to blame the couple and make them guilty of murder, then such evidence is a little insufficient.

Although the police were likely to suspect the couple because of the bloody evidence, they would immediately find out that the couple probably didn't have enough time after investigation.

If the other party really wants the police to arrest the couple as criminals, they must at least let them, the police, find nothing to do. Only when there are no other suspects, the police will really treat the couple as criminals. murderer.

The local area is a residential area. Children have to go to school and adults have to go to work at seven or eight o'clock in the morning. There is a lot of traffic there. It is impossible for the other party to be completely undetected. It is impossible to disappear completely.

Even if the murderer hid in one day in advance, it would not be so easy to leave after killing someone.And when the police will take those people back to get things is not fixed, maybe today or tomorrow, it is not wise to stay in the witness's house and wait in advance.

And there is danger.

If the police had gone up with those people and entered the door, the murderer would have been discovered immediately.

It can always be found after a detailed investigation, but because there are too many people and the amount of mixed information interspersed therein is also very large, it is very difficult to track down without suspects.

Thinking of this, Li Yancheng paused. If the murderer really wanted to put all the responsibility on the couple, then the other party must have been fully prepared.

The other party's murder was obviously premeditated, so TA would not do such a boring thing, and TA must have his own goal in doing so.

And now that the witness is dead, Li Yancheng is more concerned about what the previous witness said. The previous witness insisted that what he saw was a woman, a woman in a striped dress with long hair reaching her waist, but after passing by the police According to the investigation, they know that the person who killed the child at the time may be the father of the child-so it is also a man.

If the person who killed the child was a man, then who was the person the witness saw at the beginning?

If it was someone who had nothing to do with this case, why was the witness killed?

If he hadn't seen the murderer, the murderer wouldn't need to kill to silence him, and witnessing the death would be redundant...

But if the other party really had nothing to do with this case, why did his clothes appear in the couple's home?

There are really too many unexplainable things in it. Leaving aside all the impossibilities, Li Yancheng can only think of one possibility, that is, these are two completely different cases.If there is no relationship between the cases themselves, then all this makes sense and can be explained.

Otherwise, how could it be possible for a person to be a man and a woman?

Li Yancheng was completely immersed in his own thoughts, and did not listen to the discussions of the people next to him. He didn't come back to his senses until the people next to him called him three or four times.

"What are you thinking? Xie Wenyuan will continue to investigate the man named Ding Yang. The rest of us and I are going to visit the crime scene again. Do you want to go together? Or stay here?" Ye Kai asked.

Li Yancheng took a look at the photos pasted on the information board. He shook his head and said, "I'm in the office. I'll look at the information again."

Watching the rest of the people walk out the door, Li Yancheng suddenly thought of another thing, "Where is the information of the victim from before?"

"Isn't it right in front of you?" Li Si said. They have sorted out all the materials of this case several times, and now they are placed on the table. Although it is a bit messy, it is very complete.

Li Yancheng shook his head and said, "I'm talking about the child who accidentally slipped and fell to his death."

Li Si was stunned for a moment before he took out a document from the side and handed it to Li Yancheng. At this time, the rest of the people had already left the door.

Compared with the huge pile of materials on the table, this document seemed a bit insignificant. Li Yancheng probably flipped through it, and there were only a dozen pages in total.

"Now at this time, why are you still in the mood to read this document?" Li Si asked him.

"Isn't this case closed yet?"

"But as far as the current investigation is concerned, there is nothing wrong with this case. We have already investigated several suspects who had time at that time, and they did not do it." Li Sidao, "At the end of the investigation, the only remaining people are The couple downstairs is the couple of the second victim. But the two people's memory of the situation at that time is already blurred, and it was Sunday, and their children were doing homework at home, so there was no chance of committing the crime. .”

Li Yancheng was completely immersed in his own thoughts. He carefully looked at the documents in front of him, completely ignoring Li Si who was in front of him.

Seeing this, Li Si sighed helplessly, turned and left, and closed the door before leaving.

As for whether the murderer was a man, a woman, or two people at all, Li Yancheng could not make a judgment without further evidence.

According to the portrait drawn by his psychological profile, the other party should be a male who is about 1.7 meters five and lives alone. He is very familiar with the surrounding environment. He probably lives nearby, and the murderer may have some medical experience...

At the beginning, this profile was just a preliminary profile given by Li Yancheng, but now he has been able to confirm that the other party is such a person. The other party is good at hiding in the crowd, watching everything that happens secretly, but will not be suspected.

And the DNA test proved his profile of the murderer as a man, but it couldn't fully explain what happened to the woman in the striped dress.

Or is it that the owner of that dress is the hostess of the couple, and the disease that killed the child was not only her husband, but also her.

Perhaps it was because the two reunited by chance many years later and their old relationship rekindled, so this case came about.

But if this is the case, those two people should target the woman's husband, not their child, and there is no need to hurt their own child.

Li Yancheng rubbed his eyebrows with a headache, the case was a mess, and Li Yancheng rarely felt powerless.

One clue has not been investigated and another one appears immediately, and no one can figure out whether these clues are true or not. Such situations are indeed rare, but the more important thing is that there is no one around to help people.

Li Yancheng spends a lot of energy and time explaining every clue and every idea. He has only one person, no matter how powerful he is, he can't agree to time to investigate multiple clues. In the past, Li Yancheng would always let Zhang Xuan or Aman help, but here...

Regarding this case, Li Yancheng felt that the previous accidental fall case should be further investigated, but the rest of the people were busy with their own affairs, and no one noticed this case.

Whether Li Yancheng is the captain or not is not something he can say. No one will listen to him when Zhang Xuan and A Man are not around, and An Xiang is no longer around, and no one will be rash because of his words.

It wasn't that he was disappointed, Li Yancheng was just not used to it.

After leaving his hometown that year, Li Yancheng did not go to Tibet in the forecast, but went to G City to study, met this group of people by accident, and then stayed in G City for nearly eight years.

Eight years of habits want to change, not overnight.

Now Li Yancheng is alone in the office quietly reading the materials, which makes him regain a bit of the feeling he had in G City.

After checking the child's information, Li Yancheng noticed that the couple was on the list of people who might do something in the community.Li Si seemed to have mentioned this matter to him before, but Li Si did not tell him that the couple were the first to discover and call the police after the child accidentally slipped.

At that time, only this couple and the second victim were in the whole building. According to the statement of the couple, the child was doing homework in his room at that time. The parents heard the noise outside, so they went out to check, and were surprised to find that Someone actually fell, so the police were called immediately.

This information is very detailed, and the specific time of the couple's calls to the police at that time is recorded.

According to records, they went downstairs about 3 minutes after they found someone falling from the building. Since no one else was present at the time and they were not close to the child, they called the police directly.

In order to rule out the suspicion of the couple, the police investigated the other party at the time, and there were detailed backups of the communication records of the other party that day. The couple did call the police after the child fell from the building, and there were more than one.

Li Yancheng read this information carefully two or three times. There is indeed no record of calling 120 for help in the information. That is to say, after the child fell from the building, the couple did not call for help first, but directly called the police. .

And the next few calls were all calls to the police, not a single call for help!

Generally, if a normal person encounters this kind of thing, the first thing they do is to call 120 for help, unless they have already determined that the child died and could not be saved...

This might just be a coincidence, but it's kind of weird.
