The professional quality of the male protagonist

Naturally, all these things were taken back to the police station, and the forensic side naturally had to be busy for a while.

Ye Kai and the others didn't take any time off to persuade them. Now the case can be said to be a mess, and everyone even couldn't figure out what was going on?

When they first received relevant information about this case, it was because it was a serial homicide case specifically targeting children. When they first came into contact with the case, they did investigate that another child might have been homicide rather than an accidental mistake. Death.

But when they really thought they were making progress, they found that the direction of their investigation was completely wrong!

The child's death was actually related to his father...

So what's going on with the case now?His father killed his own child, and after being identified by the witnesses, did he also kill the witnesses?

In the office, everyone was silent. Could it be that they magnified the case because their nerves were too tense?

This is just a simple human case and has nothing to do with the serial murder case?

This case was handed over to them by the director himself, which is of great significance to this group of people. They also suspected that this was a serial murder case that was not premeditated, because it was handed over to them by the director himself, so they had already thought about it in their hearts. This is already being investigated as a major case.

Concentrate on it, concentrate on it, and don't let go of the slightest clue. Although it is not stated clearly, the competition among several people is extremely fierce. It is an ambition for most people to seek a position as a team leader in the headquarters.

But now they found that what they did was completely unnecessary. This was nothing more than an unusual private murder case.

The huge gap caused everyone to lose their minds. After calming down, they couldn't help but start thinking, what is the director's intention in doing this?

Did the director give them an ordinary button just to test them?

If this is the case, then the director's approach has really become a test. They can't resist the temptation, and they can't see the essence of the truth through the appearance. They all failed completely.

"What should we do?" Hu Xingfan asked Xie Wenyuan. The two were in an alliance, and Hu Xingfan was not good at solving such a situation.

Xie Wenyuan rubbed his forehead and shook his head helplessly.

They have nothing to do now, they can only wait and wait for the forensic doctor to give an answer.

If the evidence is conclusive, the case will be closed and there will be nothing for them.Their over-the-top drive before seemed insignificant, even a little funny.

Ye Kai was silent, Ye Zhong saw that his brother was silent, so he had no choice but to keep silent.

"Let's reorganize what happened in this case up to now." Li Yancheng said.

He got up and walked to the front of the information board, took down all the items on it, and then reposted the information one by one in chronological order.

At first they discovered that the child had been killed. From the investigation of the child’s murder, they found that the murderer might be a nearby resident. From the DNA on the child’s body, they found that the murderer might be his father. Then they found that the witness had died, and the suspect was the couple.

After simply marking the matter on the data board, the matter became much simpler and clearer.

"Should we continue to investigate the child's accidental misstep?" Ye Zhong asked.He has always been in charge of investigating this matter. So far, only a few suspects have been investigated, and the child's father is also among the suspects.

"These are two cases, why not investigate?" Li Yancheng asked back.

Li Yancheng was a little puzzled by everyone's unusual attitude today, "The case has been solved, isn't it good?"

Ye Kai was speechless. He looked directly at Li Yancheng, and asked in surprise, "It's not bad, but don't you think it's a bit boring? After working for so long, it turned out to be just an ordinary murder case."

Li Yancheng became more and more puzzled, "What we wanted to investigate at the beginning was whether it was a serial murder case or a pure homicide case? Now we have the results of the investigation."

Ye Kai opened his mouth, but finally said nothing.

"The previous interrogation is not over yet," Li Yancheng said.

He looked at Xie Wenyuan and He Xiuwen, the three of them had gone together before.

He Xiuwen looked at the others, since he had nothing to do now, he did not object to continuing the interrogation.

Xie Wenyuan didn't want to go at first, but seeing Li Yancheng going, he hesitated for a moment and nodded.

Returning to the interrogation room to interrogate the man, the three of them felt in a trance, as if it was still morning and they hadn't left yet.

Both Xie Wenyuan and He Xiuwen lost the momentum they had in the morning and seemed silent.

Li Yancheng had no choice but to pick up the information on the table and spread it out on the table, and then continued the topic of the morning, he said: "We found your hair near the victim's wound, what can you say about this matter?"

The man's hair was found on the victim's body, and he was seen going downstairs with the victim, but he himself concealed this.Those two lines alone were enough to make the police suspicious of him.

"What?" The man was obviously taken aback.

Xie Wenyuan directly took out a piece of information and handed it to him, "The doctor's appraisal report, you can look at it yourself, the DNA is 50.00% consistent, which proves that the murderer is a male related to him by blood."

"And we have evidence to prove that you went downstairs with the child at the scene of the crime, and that person can fully prove that you went downstairs with the child." Xie Wenyuan said, "In terms of time, you have the time, although The motive is unknown, but it is enough for us to charge you with murder so that the police can lock you up here for a month."

"Wait... wait what did you just say?" The man waved his hand, and he looked at the three men with a strange expression, "What did you just say, what D, DNA?"

"Stop quibbling! The DNA data in the hair will not be wrong. We have compared the DNA left in the hair of the victim with the victim, and the similarity is 50.00%." ​​Xie Wenyuan said.

"...But...how is this possible?!" The man looked at the information in surprise, and sat down on the stool, not recovering for a while.

Xie Wenyuan frowned. Was it surprising to find his DNA on the victim? ?

He Xiuwen was also a little surprised. They came here before and prepared for this man to try hard to quibble, and even made detailed preparations. As long as this man tried to quibble, they would use other methods to make him speak.

But the current situation does not seem to be quibbling, but he seems to be very surprised...

"Is there something wrong?" He Xiuwen asked.

Li Yancheng sat on the side from the beginning to the end, did not ask anything, but quietly observed the man's expression from the side.

A part of psychological profiling is also related to the behavior of the other party. No matter how thoughtful a person is, he can't hide some small reflexive movements of his body, and these small movements and micro-expressions largely reveal the personality of the person being observed. thought.

That's why Ye Kai promised Li Yancheng and He Xiuwen to interrogate him in the morning.

Mouth can lie, small movements and micro-expressions cannot.

"It's impossible!" Suddenly, the man became agitated again, he slapped the table angrily and spoke loudly, but Li Yancheng found that the other party seemed very disturbed.

"What's impossible?" He Xiuwen asked again, "If you did it, you'd better explain it quickly. Turning yourself in and being caught after investigation are two different things."

But the man suddenly fell silent. Although there was obvious anger on his face, in fact he was looking uncomfortably towards the direction of the glass on the wall and the direction of the door.

This is a basic human behavior. After encountering danger, once nervous, one will reflexively look towards the exit and wait for an opportunity to escape.

This is a stress response, and more importantly, a psychological suggestion, because people will be radioactive and look for a relatively safe place after encountering danger.

"What happened?" Li Yancheng asked.

The man looked at Li Yancheng, as if he was hesitating whether he should tell the story or not.

"Even if you don't tell, even if your wife doesn't tell, we can still find out, all it takes is time." Li Yancheng said.

Li Yancheng didn't plan to provoke him, he just told the truth.

Li Yancheng's words seemed to have broken the last line of defense in the opponent's heart. He lay on the table, covering his face with his hands, in extreme pain.

After a long silence, he finally opened his mouth and said, "The child is not mine..."

"Huh?" Xie Wenyuan was dumbfounded.

"What did you say?" He Xiuwen was not much better.

"I said the child is not mine, the child is not my own." The man said.

Once he opened his mouth, it was a lot easier to talk about the following things, but the man obviously hadn't calmed down yet, and when he talked about this matter, he was a bit upside down.

The child was not born to the two couples, no, to be precise, it should not be the man's.

The child was brought by his wife. When the two got married, his wife was already pregnant, and the child was born later...

They tried to have a baby, but it didn't work out, and luckily no one else knew about it, so they decided to just raise the baby that way.

In the past ten years, no one else knew about it, and the two of them never mentioned it to outsiders, not even the man's parents, who were the child's grandparents.

This secret is a scandal that must not be exposed to the two of them, so the two of them have always kept their mouths shut and never mentioned it.

If it hadn't happened this time, and the police put the evidence in front of him, the two of them would never have thought of it.

After hearing the man's words, Xie Wenyuan and He Xiuwen were stunned, and Li Yancheng was also very surprised, but he didn't show it like the other two.

The people standing outside the glass also stood there in a daze, they never thought that such a moth would come out of the clues they had finally grasped.

"Have there been any signs of this before? Have any men come to you, or have any new residents moved in nearby?" Li Yancheng reacted before everyone else. If the other party was the father of the child, then because he didn't know If you killed your own child for a famous reason, then the other party must have had contact with the child.

The man thought for a while, but finally shook his head helplessly, "No, we have lived in that community for nearly ten years, and the houses there are not rented out, and there are not many residents who have moved in in the past ten years. And if anyone approaches the child , we know for sure..."

"Do you have any clues about the child's father?" Li Yancheng asked.

If the DNA is not from this man, then the murderer is almost certain to be the father of the child.

Compared to other people's surprise and inability to get around the corner, Li Yancheng was already thinking about the next thing, "If the DNA is not yours, we need to control the other party as soon as possible and arrest him."
