After everyone went to get busy, Zhu Ting was also driven to sleep by Zou Cheng.

Zou Cheng sat in the conference room of the police station and began to think about the current case.

There was no one in the conference room, and Zou Cheng began to talk to himself.

"You got them first, and now you let them go, of course, kill them first, and then let them go. ”

"You make them look calm, peaceful, you kill them with a sedative. ”

"But these are not right, where has your aggression gone, where have your needs gone, what are you doing?"

Zou Cheng doesn't understand why the current murderer has changed so much.

Just when Zou Cheng was thinking about these questions, more than three hours had passed unconsciously, and Zhu Ting had already woken up.

"Brother Zou Cheng. Zhu Ting came to the conference room and saw that Zou Cheng was still sitting here.

Zou Cheng nodded to Zhu Ting and said, "Ready to eat." ”

Just as Zou Cheng and Zhu Ting were about to go to dinner, a police officer ran back.

"Inspector Zou, we've already surveyed the area within and outside the triangle you drew three kilometers. The officer said.

"What discovery?" asked Zou Cheng.

The officer had some bad premonitions: "We have found six similar cases of children running away from home and going missing. ”

"Six?" Zhu Ting was a little surprised.

Zhu Ting said: "There were three cases in the front, and now there are six more cases, isn't this nine?"

Nine?

There are too many, Zou Cheng said: "Among these six cases, there should be some yes or not, but there must be yes, let's all count it now." ”

Although he didn't know how many were and how many were not, Zou Cheng knew that there must be something inside.

Zou Cheng asked the police officers to mark the six cases on the map.

After the police marked it, everyone saw the suspicions.

Zhu Ting said: "Brother Zou Cheng, the previous cases were very dense, and they were all concentrated here. ”

"Yes, Inspector Zou, but the current three cases seem to be very casual. The officer said.

Zou Cheng nodded, but Zou Cheng turned to say, "Although these are strange, there are even more strange things. ”

"What?" the officer asked.

"Why did the murderer change his modus operandi?" Zou Cheng frowned, which he couldn't understand at all.

Zou Cheng said: "The original modus operandi has allowed the murderer to get away with it, because at present, he has committed at least three or more crimes, or even more." ”

But no one knows, because he targets children who have run away from home, or who he has caused them to run away from home. ”

"And there is no body, and the child has run away from home, so it is natural for everyone to think that the child has gone somewhere else now, so the murderer is safe. ”

"But why, the murderer changed his modus operandi. ”

Zou Cheng's words made Zhu Ting and the police officers bow their heads and think.

Yes, although it is incredible, the murderer seems to have really avoided danger, and he has not aroused anyone's suspicion.

But why is the murderer now changing his modus operandi?

Not only the modus operandi, but also the choice of the victim has changed.

Just when Zou Cheng was in the conference room, Liang Yingqi ran in, holding his laptop in his hand.

"What's wrong?" Zou Cheng was flustered when he saw Liang Ying crying.

Liang Yingqi put his computer on the table and said, "I have made a new discovery." ”

Say. Zou Cheng said.

"The priest's church is a church open to children, and their leaflet has a web address on it, which is a web page. ”

But digging deeper, I found that there was actually a chat room hidden underneath. ”

"Chat room. Zou Cheng hurriedly ran over to look and found that there was indeed a chat room.

And it's a peer chat room, Liang Yingqi continued: "I checked, and the people in it are all children, and they are all children with the same problem. ”

"You mean domestic abuse?" Zhu Ting asked.

Liang Ying shook her head and said: "What is serious is domestic abuse, and there are some parents who are divorced, or those whose parents are stricter, and there are family reorganizations. ”

"In general, it's all kids who feel lonely. ”

Seeing the chat room in front of him, Zou Cheng felt that his explanation could be explained.

"Children with the same problems talk to each other so they don't feel lonely," Zou said. ”

"It's a place where they feel safe, where they trust each other. ”

Zhu Ting continued Zou Cheng's words and said: "The murderer did not target children who ran away from home, but instigated them to run away from home. ”

"When did this chat room exist?" asked Zou Cheng.

"I asked the priest, and it was only a little over half a year. Liang Ying said.

"So the murderer should have started using this recently, Wu Haochen, Luo Zheng and the last victim, these three victims were found using this. Zou Cheng thinks that's it.

However, Zou Cheng said: "But the early ones are not, the early children were found through another channel." ”

Zou Cheng said to Liang Ying: "Can you check this chat room, the previous content?"

Liang Ying cried and said: "You can check it, but I'm afraid it will be very troublesome." ”

"The trouble also needs to be investigated, and there is also monitoring this chat room, if the murderer is inside, I hope to be able to determine the location of the murderer. Zou Cheng handed over this idea to Liang Yingqi.

Liang Ying nodded and said, "I will ask my colleagues in our department to assist me." ”

"Someone is online. Suddenly, Liang Ying said.

"Keep an eye on him. Zou Cheng said.

But Liang Ying looked at it for a while and found that it was full of children's conversations, all of whom were expressing their unhappiness and the like.

"If there is an account that has a tendency to make children run away from home, then that person is the murderer. Zou Cheng now feels that the murderer must be here.

Zhu Ting said a little unhappily: "Father, they didn't tell us this in advance, if we told us in advance, we could have avoided a lot of detours." ”

Zou Cheng thought that what Zhu Ting said was right, but he also felt that the priest did not tell them because the priest did not know that the murderer had used this thing.

This thing didn't seem important to them, so they didn't even think to talk about it.

Now that he has found it, Zou Cheng hopes that it will not be too late, he hopes that the murderer can be found and brought to justice.

Liang Ying cried down to monitor the chat room, Zou Cheng looked at the map and said: "This is the place where we know the early victims live, we can see that it is very dense, and it is concentrated in this area. ”

"When the killer first started committing the crime, it was the hunting area. But now the scope is very wide, because the murderer used the Internet, but these previous cases are also representative. ”

The police officer understood Zou Cheng's words, and he said: "Inspector Zou, the original victims, are all concentrated in a specific area, which can only show that the murderer lives here. ”

But Zou Cheng shook his head and said: "There are many people living here, but why can the murderer accurately find the person he wants to find and find the target he wants." ”

"Inspector Zou, what you mean is that when the murderer first committed the crime, he was also looking for a specific child. A police officer asked.

Zou Cheng said: "Obviously not, our investigation also confirmed this, there are children who have been abused. ”

Zhu Ting said to Zou Cheng: "Brother Zou Cheng, how does the murderer know the situation of every child, does he know every child?"

Zou Cheng looked at the map, although these areas are very dense, but in real life, there is still a distance.

It is impossible for the murderer to know all the children in this and know the condition of all the children, which is not very scientific.

It is now known that there are three children, and then six possible children have been found, so it is nine.

It may not be so many as nine, but it may be eight, seven, six.

How did the murderer know these children, and knew the condition of these children, but there were no online chat rooms at that time, so they all gathered together.

So what exactly is the reason?

Don't say that Zou Cheng can't figure it out, many people can't figure it out, and they don't quite understand this issue now.

Zou Cheng said to the police: "First go investigate, the six children who may have been killed by the murderer, and see if they ran away from home and were bewitched by the murderer." ”

"Understood, Inspector Zou. "The police know how to investigate, and as long as there is domestic abuse, then it is likely that the murderer has been tricked away.

As for Zou Cheng and Zhu Ting, they can't think of a reason to come now, so they can only go to dinner first.

After eating, I came back to the police station in the afternoon, and waited for no news.

After that, Zou Cheng sent Zhu Ting home, and Zhu Ting was going to class tomorrow.

Let Zhu Ting rest early in the evening, and then Zou Cheng called Director Song.

Originally, when it came to the recording of werewolf killing, Zou Cheng could delay it and slowly quit.

But now, Zou Cheng has to take a leave of absence, because this case has not yet been resolved.

When Director Song heard Zou Cheng's words, he said helplessly: "I understand, you want to be a detective, you can rest assured to solve the case, you don't have to worry about the show." ”

"There are a lot of candidates for werewolf killing, and I've left it to me. ”

Hearing Director Song's words, Zou Cheng nodded and said, "Thank you, Director Song, if it can be done this time, I will take advantage of the situation." ”

"It's okay, you have to leave sooner or later anyway, you can't stay, come on and solve the case. Director Song encouraged Zou Cheng.

Zou Cheng hung up the phone and made a call to Liang Yingqi, who was going to work overtime tonight.

She's going to keep an eye on the chat room, and she's going to investigate what's going on in the chat room.

It's not that difficult, because the chat room is so easy to set up, it's basically a common thing now, and it's not used by anyone.

However, the content in it is huge, and it takes a lot of work to find useful data in so much data, and to keep an eye on those new data that emerge one after another.

Zou Cheng asked Liang Ying to cry hard, and let himself know if there was news.
