"I think it's not the first time that this murderer's technique is so clean and neat. Maybe he has killed someone before these two cases, but we have not discovered it. After all, there are many missing people every year. Judging from his current high-profile but without traces, it's very simple to kill someone but find it." Hao Xin said what he knew with an objective and inferred method.

"You keep talking." Zhou Qingmao listened, feeling that there might be a breakthrough if he thought about this.

"Since he did not directly expose the murder before this, it may not be because of the fear that the traces would be discovered, but because the deceased had a connection with him. In that case, even if the traces were clean, there would be a possibility of being suspected. Therefore, it is hidden. We can report the case from those relatives, friends and lovers. The life background of the reporter is similar to that of serial killers. Starting from this, it may be effective." She was also asked when she thought that Gao Cheng would use this method to expose her.

"What do you think?" Zhou Qingmao looked at the others.

"I think we can give it a try, after all, we have no clue now." Yu Hongze first agreed.

"I also think Ayu's speculation is very likely, so I can try it." Zhao Guang came in two years earlier than Yang Ruoyu. He was also a newbie before her, full of vitality, and agreed with Hao Xin's statement.

"Try it."

"I agree."

"I have no objection."

"Anyway, I have no idea now, so I can try another way." Liu Bao is the biggest brother and has always been conservative, but this time he really has no idea how to start, so he actually agreed.

"Okay, Yuling, you can bring people to retrieve the disappearance cases in recent years and investigate the background of the people around them." Zhou Qingmao began to assign tasks, assigning tasks to everyone who is good at.

The task assigned by Hao Xin was under Liu Yuling. The original owner was originally very outstanding in computers and entered the serious crime team as soon as he entered the police station. Computers were popularized more than ten years ago, but the computers were connected to the Internet and would be hacked by some hackers. Therefore, all cases have paper materials, and some important cases will not even be entered into the computer.

What they want to investigate is a case of missing persons. Such cases are generally connected to the country, so they can be investigated directly online, but there are many such cases every year and the workload will be relatively huge.

"Let's start checking in the past few years." Hao Xin felt that the goal needed to be narrowed.

"Yes." Because both cases happened in their city, it is quite possible that the murderer was a local. Of course, it is not ruled out that he came here later. In short, it is better to investigate the local disappearance case, and soon the missing case of Gao Cheng's girlfriend was found.

Of course, Hao Xin is responsible. After all, she knows that this person is the murderer, and just guides everyone to suspect this person. "Sister Yuling, look at this case. The man's girlfriend is missing, which is the case he reported, and his family is very in line with the growth environment of a serial perverted killer."

Liu Yuling walked over and took a look: "Indeed, her father's alcoholic mother was a gambler. She was abused and beaten by her parents since she was a child. She was talented. Her father died of alcohol poisoning, her mother disappeared, and her girlfriend disappeared."

"And look at his girlfriend. According to the investigation, his girlfriend also likes gambling. Maybe it was because of this stimulation that he thought of his mother and killed her girlfriend. After the treatment was done, she called the police and said she was missing. If he was the murderer of these two murders, it would be very simple to erase the traces of killing her girlfriend." Hao Xin pointed to the information and said.

After knowing the real murderer, he can reason about his impossible criminal process based on some clues.

"It's really suspicious. Find out the information about this case and wait until the meeting is held to discuss it." After Hao Xin's guidance, Liu Yuling also felt that Gao Cheng was still very motivated to commit the crime.

Zhou Qingmao had a meeting in the afternoon and asked Liu Yuling: "How is it? Is there anything I can do?"

"There are 3." Liu Yuling nodded and took out three case files. "The victims of these three cases have people around who are similar to those of serial killers' growth."

Hao Xin didn't expect to find three, except Gao Cheng, two other men and women. The man Zhu Qi has liked to abuse animals since he was a child, while the other woman, Sun Li, was abused by boys over girls since he was a child, and her personality is very gloomy.

Liu Yuling talked about the relationship between three people and the missing person. Among them, the most suspected was Zhu Qi, who abused animals. Because he abused animals, he liked to peel and chop the animals up. Of course, from the perspective of the scheme, but Zhu Qi's criminal behavior was not hidden, so after the discussion finally, they all set their targets on Gao Cheng.

He has a high IQ and is good at computers. He might be able to tamper with surveillance videos. Then all Gao Cheng's growth information was investigated, mainly in school and company. After two days, Gao Cheng's suspicion became increasingly serious, but there was no evidence.

Hao Xin has no choice but to follow her, and there is only one day left before the third case in the original owner's memory. Fortunately, someone in the bureau has already stared at Gao Cheng. I think he should have noticed it with his ability and should not do it casually.

However, she was slapped in the face. Under the scrutiny of the police station, the third case still happened. Except for staying at home and the company, he was not in the police's sight, but everything else was there. However, it can be confirmed that the other party had not left the company or the police when he was home, which means that the other party has absent proof now.

Hao Xin even suspected that Gao Cheng not only had high IQ, but also had special abilities. How did he avoid the police's sight and commit crimes? Hao Xin was really crazy. She prefers frontal quarrels instead of conspiracy analysis that is constantly being cut and messy.

It is also because of this that the police, who were already 90% sure, also suspected that they had made a mistake, but at present, he was the most suspicious. Therefore, the stalking continued, but it did not pay as much attention as before. Hao Xin volunteered to be the one who stalking.

There are still two weeks before the fourth victim appears, and she doesn't believe that the other party really has no flaws. It's just that Gao Cheng is basically at the company's two points and one line. Except for buying vegetables, he rarely goes out. She can't pretend to monitor. Wait, have she forgotten something? Who is she? She is the Taoist tyrant Hao Xin, and she has golden fingers!
