The police in Beiqian were very powerful. With Zhao Yu's greeting, they immediately summoned police officers from various branches in Beiqian to participate. The number of people reached hundreds of people, which was a huge momentum.

Zhao Yu divided the police into 10 groups, 9 of which were responsible for investigating the deceased in the devil's case one-on-one. Zhao Yu asked them to handle the situation according to the highest specifications and to re-examine the situation of each deceased before his death, and not let go of a single detail. The more information they get, the better.

As for the group that was left behind, it focused on restoring Han Kuan's movement trajectory and investigating Han Kuan's situation when he moved north.

After Zhao Yu assigned the task, Director Xu Yihua also emphasized discipline in public and announced the reward and punishment system, requiring police officers to perform their duties conscientiously and complete the task as soon as possible. Those who can obtain important clues will be rewarded for their merits; and if anyone finds that the investigation is not serious and the discipline is lax, they will be punished and severely punished!

The director said, and naturally the police did not dare to neglect them. After receiving the order and leaving, they immediately joined the investigation.

After that, Zhao Yu called Wu Xiumin again and asked the Golden Police not to be idle either. They must send additional police force immediately and then re-examine all the things related to Han Kuan to see if there is any possibility of finding new clues?

Of course, the same is true for Yaoming, and all the tasks there were handed over to Wang Can.

In this way, under Zhao Yu's call, a massive investigation was launched in three cities at the same time.

Although the influence of the demon case is not as good as the headless female corpse case, it ranks one of the five unsolved cases. When local police received orders to understand that they were investigating the famous demon case, they naturally tried their best and put in full force.

In just a few days after that, various materials were summarized into the special dispatch office of the Beiqian Police Station. When the information was printed out, it could be described as piled up.

However, even though there is so much information, Zhao Yu still needs to read it one by one in detail!

In the past few days, Zhao Yu has really worked hard! He was not untied, and almost all his food and accommodation were in the office. He carefully checked every piece of information without missing any details!

As for Zhao Yu's tireless work attitude, I would like to talk about the local police officers, even the colleagues in the special team were also surprised by him. Although they all knew that Zhao Yu was stubborn, it was rare to be so stubborn that it was so awesome!

Especially Miao Ying, who had been with Zhao Yu, was so surprised that Zhao Yu's qualitative transformation was hard to describe in words. She never expected that the unrestrained, arrogant and unruly hooligan in the past would have such persistence and tough side.

Whether it is gratitude or admiration, in short, Zhao Yu's never-give-up spirit flowing in his bones deeply moved Miao Ying, making Miao Ying more certain that he did not choose the wrong person at the beginning!

Seeing Zhao Yu performing like this, the morale of the team members also increased greatly and were unwilling to fall behind. Over the past few days, they worked together to review a lot of information and analyze a large number of clues. Although no decisive evidence has been found yet, the murderer, which is Han Kuan's guess, is becoming more and more clear.

Sometimes, solving a case is like a layer of window paper, once it is broken, it is clear at a glance.

In a few days, Zhao Yu carefully browsed the novels published by Han Kuan in chronological order, and then he was shocked to find that the answers they had been searching for before had been reflected in Han Kuan's books.

Although Han Kuan's novels are not very famous, if you read them carefully, you will find that his logic is very strong. Moreover, the more he writes later, the more he focuses on the psychological aspects. He can accurately grasp the psychological state of each character, whether he is a criminal or a law enforcement officer.

Therefore, after reading the whole article, Zhao Yu finally realized a shocking fact: Han Kuan not only continued to grow in his creation, but also underwent a qualitative transformation. He was already an absolute psychological expert!

Therefore, he had the strength to deceive the police, and even made Zhao Yu feel at his word!

In addition to the novel, Zeng Ke also discovered Han Kuan’s major problems in a video material.

It was an earlier police interrogation video. In the video, Han Kuan cried bitterly because of his wife's death, but the words he said caught Zeng Ke's attention.

During the interrogation at that time, Han Kuan said in tears: "You said you understand me, but who can you know what it feels like to lie in the blood of your wife?"

This sentence seems nothing wrong at first glance, but if you analyze it carefully, it will make people feel strange.

For this reason, Zeng Ke specially asked Ba Chen to verify the matter. Based on Ba Chen's recollection and verification, he also felt that it was unreasonable for Han Kuan to speak like this.

Because, after the police arrived at the scene of Zhang Jingru's death, because Han Kuan was holding a knife in his hand, the police naturally thought that he wanted to commit suicide by committing suicide, so they sent him to the hospital for emergency treatment as soon as possible.

At that time, Han Kuan's clothes were covered with blood, and the hospital had to take off his bloody clothes, clean him up, and put on the hospital's hospital gown.

Because it was related to the murder case, the bloody clothing was naturally taken as evidence by the police and sent to the forensic department for inspection.

According to the doctor's test report, Han Kuan was in a severe coma at the time and did not wake up until after 8 o'clock in the morning. So he couldn't know what happened last night?

Moreover, Ba Chen remembered clearly that until the police treated Han Kuan as a suspect in killing his wife and took him to the police station from the hospital, he didn't even know that Zhang Jingru had died.

After that, although the police had shown him photos of the crime scene for the need for interrogation, after careful consideration, Han Kuan's words were still unreasonable. Even if he knew that he had been lying in his wife's pool of blood, how could he feel?

This sentence obviously betrayed him because he was the murderer who killed Zhang Jingru! Before he fell into a coma, he was already lying in Zhang Jingru's pool of blood...

In addition to the above two things, they also gained new gains in investigating the deceased in the devil's case. Among them, the group of police officers in charge of investigating the old lady in their 60s finally found the old lady's old neighbor through unremitting efforts.

According to one of the neighbors, the old lady had been exposed to slaughtering small animals during her lifetime. Moreover, the neighbor was very sure that the rumor came from the Internet.

After obtaining this clue, the police immediately launched an investigation around the Internet, and finally found the root cause.

It turns out that in the year when the Demon Case occurred, chat software like QQ had not yet been widely popular. If you want to chat online, you can only choose a chat forum called Youyuan. It is an open chat platform, similar to today's chat group. After people enter, they can chat and make friends, which is very popular.

However, this kind of chat platform has certain regional restrictions, which are only popular in a certain city or a certain area.

It is said that the rumors about the old lady's murder of small animals were spread from this chat platform. It is conceivable that the reason why the old lady attracted the attention of the murderous demon is likely to be from this!

So, Zhao Yu and others finally understood how Han Kuan could get news so quickly and find the target!

He must have obtained it through this kind of chat platform. At that time, the forum did not require real-name system and the management was not strict. He just needed to start a random place, and a large group of people would provide clues for him.

However, now, time has passed, and after so many years, the data is no longer available. Besides, even if Han Kuan’s chat records can be found, they will not be of any effect.

Therefore, although the direction of the investigation is very clear, all the evidence obtained by Zhao Yu and others is soft, and this evidence is invalid.

To prove that Han Kuan is guilty, they must find more certain evidence. However... Zhao Yu has been opening the hexagram for several days, but still has not even opened the "Gen" hexagram. Is the demon case really an unsolvable unsolved case?

No!

Zhao Yu's answer is extremely firm!
Chapter completed!
