The professional quality of the male protagonist

The specific checking of the situation was still not so fast. The tasks of nearly 30 people kept them busy all night.

It wasn't until after nine o'clock the next day that the verification task was finally completed!

Among the people who were on the scene in both cases, there were more than a dozen people who did not meet the conditions to commit the crimes. Among the remaining dozen people, according to the specific situation at the time, after detailed investigation, a few more were ruled out. There are only four people left.

What's very interesting is that one of these four people was the victim's father, the man who had been hugging his wife and comforting her when Ye Zhong and the others went to inquire about the situation.

The other three people all live in this community, but the three people are not sitting in the same building, and so far it has not been found that the three people have any tendency to fight.

Now that there are specific suspects, the most direct way according to Ye Zhong's approach is to directly compare the DNA of the four people in detail. Once the comparison results come out, the truth will be revealed.

This way of doing things is obviously different from Zhang Xuan's way of doing things. If Zhang Xuan's way of doing things is followed, they will definitely check the evidence that the four people were not present at the time, and investigate the background of the four people and the situation of the victim's family in detail.

It's not that Zhang Xuan and the others couldn't think of this way, it's just that DNA firmness requires certain skills and equipment, and it also takes a certain amount of time.

Wanting to identify so many DNAs at the same time is too restrictive for Zhang Xuan's place, and Oman will take at least three or four days to complete even at a fast speed.

But it is different here, most of today's reports here are of course arranged according to the specific circumstances of the case, as long as Ye Kai applies for them, they will be able to get the answer tomorrow morning.

In the office, Ye Kai sorted out the materials of the four people, took the materials, and stood up, "I'll go to the identification department, and get back the DNA identification report of the victim's hair by the way, Ye Zhong, find some people to extract the DNA , Remember to be careful on the way, don't provoke them... The rest of the people continue to investigate the situation of these four people."

"Why am I doing this kind of errand again?" Ye Zhong pouted dissatisfiedly.

Faced with Ye Zhong's childish behavior, his brother Ye Kai completely ignored him and left the office straight away.

The departure of Ye Kai and Ye Zhong made everyone in the room heave a sigh of relief. After a non-stop busy night, everyone was tired.

In the corner of the house is still the last night they ate my supper, the leftover garbage, after a night, the smell is a bit strong.

Li Yancheng was sitting in the corner by the window, Xie Wenyuan was lying on the table next to him, drowsy, and the rest of the people in the room were in a similar state.

Li Yancheng looked at it, and finally got up and went downstairs with the garbage.

He is not very clear about the environment here, because he has been busy with this case since he arrived here, so it took a little longer to walk to the trash can after carrying the trash downstairs.

When he went upstairs again, the house was busy again without stopping.

Li Yancheng stood at the door and took a look. Li Si and the others pasted the photos of the victim's family members on the file board. Several people gathered around the file board to discuss something again. They seemed to have discovered some new clues about the family.

Ye Kai has also come back, holding a report excitedly at this moment, Xie Wenyuan, who was lying on the table, also gathered around the file board, rubbing his chin and listening carefully to the discussions of other people.

Li Yancheng stood aside and watched for a while, but he couldn't understand what everyone was doing, "What's wrong?"

"Ye Kai got the DNA of the previous murderer just now. Guess who it is?" Li Si said excitedly, her cheeks flushed because she was so excited.

Li Yancheng lowered his eyes and thought, the answer that shocked Li Si and the others must be within the scope of their previous contact, maybe they had investigated the other party but missed it.

Sure enough, before Li Yancheng opened his mouth to speak, Li Si couldn't wait to continue: "The DNA is 50.00% similar to the victim's DNA, do you know what that means? The 50.00% similarity in DNA can only mean one thing. One thing is that the murderer and the victim are father and son."

"Father and son?" Li Yancheng was dumbfounded, the man in his impression was not eye-catching, even when Ye Zhong asked about his situation at his home, the other party seldom spoke, most of the time it was his wife who answered, he was just He just sat quietly by the side and hugged her, comforting her from time to time.

The man looks ordinary, not outstanding, with a public face, so that most people would almost forget the other person's appearance if they didn't see the photos posted on the information board.

"But if it is his father, it is very likely that he took it when he was at home, so it cannot be used as direct evidence." Li Yancheng said.

"Yes, if it's just like this, it really can't be used as direct evidence, but it's not just like that. Do you still remember the people we investigated before who might kill people? His father was among them. When the first child accidentally fell from the building, his father said He was in the company, but he lied, and we have found no alibi at the time of the crime." Li Sidao.

"At that time, the place where he worked was only ten minutes away from the current community, and the round-trip time would not exceed half an hour. Moreover, when his son died this time, he went out with his son. Someone saw them going out together. But the couple didn't tell us about it, and his father didn't tell us that he saw his son's death." Li Si said.

Li Yancheng walked aside and looked at the appraisal report, it was indeed as Li Si said.

If so, then his father's suspicion is unintentionally the greatest.

"Have you ever interrogated his father?" Li Yancheng suddenly became interested, because his impression of his father was somewhat different from the portrait he had drawn before.

The victim's father was not short in height, and he was also very muscular. His taciturn personality was a good match, but Li Yancheng always felt that something was wrong.

The portraits of the characters he profiled should be smaller and cowardly, less likely to be eye-catching, and less dangerous.

Children usually have a strong sense of crisis. Although they are not sensitive to some fraud or abduction, if someone approaches with murderous intentions, children can always be more keenly aware.

Every frown and smile of an adult is extremely obvious to a child.

It's hard to imagine a child easily letting go of a tall and strong man, but...

If the other party were father and son, all this would make sense, but Li Yancheng still felt that something was wrong.

"Not yet, we just sorted out here, and we want to go to the interrogation after sorting out all the materials." He Xiuwen said.

Interrogation also requires skills. If you interrogate suspects without knowing anything, you may end up with nothing.

"I'll go." Li Yancheng said.

Excited Li Si looked at Li Yancheng, seemingly a little surprised.

Ye Kai had other considerations, "Then Li Yancheng and He Xiuwen go in, and we will watch from the outside. Here is the information we sorted out before. You two should take a good look at it before interrogating, so as not to miss anything. "

"I'll go too." Xie Wenyuan said.

Now that the case has been investigated, Xie Wenyuan is somewhat annoyed. At first he was played by Li Yancheng, but later the investigation found nothing, and then he was played by Li Yancheng again...

"It's fine for two people to go, but it's not good if there are too many people." Ye Kai said, "And we have his wife to interrogate. If possible, the two sides can go together faster. A case can be delayed for a few days, which is too long."

Xie Wenyuan wanted to say something to refute, but Li Yancheng beat him and said: "Let him go together, it will be useful."

When Li Yancheng said that, Ye Kai naturally wouldn't say anything. He turned to look at the other party, He Xiuwen.

He Xiuwen was silent, noncommittal.

Several people took their own documents and looked in the office for a while, and then went to the interrogation room after confirming that there was no problem.

Because the victim's room was cleaned up before, the two people were brought back together with the witness, and the three of them were not allowed to leave within 48 hours. Now it is just convenient for them to investigate.

The two were sent to two interrogation rooms separately. Ye Kai and Zhang Xia went to interrogate the woman, while Li Yancheng, Xie Wenyuan, and He Xiuwen entered the room to interrogate the man. The husband and wife seemed a little uneasy being separated. Before Li Yancheng and the others entered, the two of them looked outside the room anxiously, and sat back on their chairs until they saw someone coming in.

Seeing that three people came in suddenly, the man seemed even more disturbed, "Why did you lock us up? I want to sue you, this is illegal detention!"

"Sir, this is not detention, it's protection." He Xiuwen sat down opposite him, and then put the materials he brought on the table.

He brought a lot of things, including some photos of the crime scene after the child's accident.

Putting the photos on the table one by one, He Xiuwen pushed the photos in front of the other party.

The man just glanced at the photo and turned sideways, looking away from it, unwilling to take another look. , There was some uneasiness in his expression, it seemed to be very uneasy.

The photos of the child after the accident have not been modified in any way, with a bloodless face, lying there lifeless, unable to move or speak...

"Protection? Why didn't I know it was protection? Did you protect me like this? Something happened to the child, why don't you catch the murderer and catch us?" Seeing that the photos were still there, the man immediately waved all the photos away , turned them all over and placed them on the table away from you.

"We found evidence that the child went out with you that morning." He Xiuwen cut to the chase.

The man immediately showed his feet when he heard the words. Although he didn't make much movement, this man was obviously not good at lying, and his expression was too stiff.

"We are here to investigate the cause of your son's death. If you conceal it intentionally, it will bring us a lot of trouble, and because of your previous actions and concealment of the incident, we now suspect that you did not report it or that you are the murderer. "
