The Beiqian police force was very helpful. As soon as Zhao Yu asked them to, they immediately summoned the police officers from various branches in Beiqian to participate in the investigation. The number of police officers reached hundreds.
Zhao Yu divided the police officers into ten groups, nine of which were responsible for investigating the victims of the Devil Case one-on-one. Zhao Yu requested that they follow the highest standards and thoroughly investigate the circumstances of each of the victims before they died. Not a single detail could be missed. The more information they could get, the better it would be.
As for the other group, they were responsible for retracing Han Kuan's movements and investigating Han Kuan's situation in Beiqian in detail.
After Zhao Yu assigned the tasks, Bureau Chief Xu Yihua also emphasized discipline and announced a reward and punishment system. She asked the police officers to perform their duties seriously and work overtime to complete the task as soon as possible. Those who could find important clues would be rewarded according to their merits, and those who were found to be lax in the investigation would be severely punished!
Since the bureau chief had given the order, the police officers naturally did not dare to neglect it. After receiving the order, they immediately devoted themselves to the investigation.
After that, Zhao Yu called Wu Xiumin and asked the Golden City police to send more police officers to thoroughly investigate everything related to Han Kuan to see if they could find any new clues.
Of course, the same was true in Yaoming, so Officer Wang was responsible for all the tasks there.
In this way, under Zhao Yu's call, a massive investigation was carried out in the three cities at the same time.
Although the Devil Case was not as influential as the Headless Female Corpses Case, it was still one of the five major unsolved cases. When the local police received the order and learned that they were investigating the famous Devil Case, they naturally went all out and did their best to carry out the investigation.
In just a few days, all kinds of information were gathered in the office of the Special Investigation Group in the Beiqian Police Station. When the information was printed out, it could be described as a mountain.
However, even though there was so much information, Zhao Yu still had to go through it one by one!
In the past few days, Zhao Yu really worked hard! He spent almost all of his time in the office, seriously reading every piece of information, not letting go of any details!
Not to mention the local police officers, even his colleagues in the special investigation group were impressed by Zhao Yu's tireless work attitude. They were amazed by him. Although they all knew that Zhao Yu was stubborn, it was rare for him to be so stubborn to such an extent!
This was especially true for Miao Ying, who had been with Zhao Yu for a long time. She was so surprised by Zhao Yu's transformation that she could not find words to describe it. She had never imagined that the unrestrained, arrogant and unruly scoundrel in the past would actually have such a persistent and tenacious side.
Regardless of whether it was gratification or admiration, Zhao Yu's spirit of never giving up had deeply touched Miao Ying. Miao Ying was even more certain that she had not chosen the wrong person!
Seeing Zhao Yu's performance, the morale of the team members was greatly boosted. They did not want to fall behind. In the past few days, they worked together to look up a lot of information and analyze a lot of clues. Although decisive evidence had not yet been found, the speculation that Han Kuan was the murderer was becoming more and more clear.
Sometimes, solving a case was like a piece of paper on a window. Once it was pierced, everything would become clear.
Over the past few days, Zhao Yu carefully browsed through Han Kuan's published novels in chronological order. He was surprised to find that the answers they had been looking for were already in Han Kuan's books.
Although Han Kuan's novels were not very famous, if one read them carefully, they would find that his logic was very strong. Moreover, the later he wrote, the more psychological aspects he focused on. He was able to accurately grasp the psychological state of each character, whether they were criminals or law enforcement officers.
So, when Zhao Yu finished reading Han Kuan's novels, he finally realized a shocking fact: Han Kuan had not only continued to grow in his writing, but he had also undergone a qualitative transformation. He had already become a true psychologist!
Therefore, he was fully capable of deceiving the police and even tricking Zhao Yu!
In addition to the novel, Zeng Ke also found a major problem with Han Kuan in a video.
It was an earlier police interrogation video. In the video, Han Kuan was crying bitterly because of his wife's death. However, something that he said caught Zeng Ke's attention.
During the interrogation, Han Kuan said in a tearful voice, "You say that you understand me, but do you know what it feels like to lie in my wife's blood?"
At first glance, there seemed to be nothing wrong with Han Kuan's words, but if one analyzed them carefully, they would find it strange.
For this reason, Zeng Ke specifically asked Ba Chen about it. According to Ba Chen's memory and investigation, he also felt that Han Kuan's words were unreasonable.
When the police arrived at the scene of Zhang Jingru's death, they naturally thought that Han Kuan wanted to commit suicide because he was holding a knife in his hand. So, they immediately sent him to the hospital for emergency treatment.
At that time, Han Kuan's clothes were covered with blood, so the hospital had to take off his bloody clothes, clean him up, and change him into a hospital gown.
Because it was related to a murder case, the bloody clothes were naturally taken as evidence by the police and sent to the Forensics Department for examination.
According to the doctor's test report, Han Kuan was in a severe coma at the time, and he didn't wake up until eight o 'clock in the morning. So, it was impossible for him to know what had happened last night.
Moreover, Ba Chen clearly remembered that Han Kuan didn't even know that Zhang Jingru had died until the police took him to the police station as a suspect in the murder of his wife.
After that, although the police had shown him photos of the crime scene for interrogation purposes, when he thought about it carefully, he found that Han Kuan's words did not make sense. Even if he knew that he had been lying in a pool of his wife's blood, how could he have felt anything?
This sentence obviously betrayed him, because he was the murderer who killed Zhang Jingru! Before he fell into a coma, he had been lying in a pool of Zhang Jingru's blood.
In addition to the above two things, they also made new discoveries in the investigation of the Devil Case's victims. Among them, the group of police officers who were responsible for investigating the 60-year-old woman finally found the old woman's old neighbor through unremitting efforts.
According to one of the neighbors, there was a rumor that the old woman had tortured and killed small animals when she was alive. Moreover, the neighbor was very sure that the rumor had come from the Internet.
After getting this clue, the police officers immediately investigated the Internet, and they finally found the source of the rumor.
It turned out that in the year of the Devil Case, chat software such as QQ had not yet been widely available. As such, the local young people who wanted to chat online could only choose a chat forum called Friend Forum. It was an open chat platform, similar to today's chat groups. After people entered, they could chat and make friends. It was very popular.
However, this kind of chat platform had certain regional restrictions, which meant that it was only popular in a certain city or a certain region.
It was said that the rumor that the old woman had tortured and killed small animals had come from this kind of chat platform. It was conceivable that this was the reason why the old woman had attracted the attention of the murderous demon!
So, Zhao Yu and the others finally understood how Han Kuan had been able to get the news so quickly and find his target!
He must have gotten the information through this kind of chat platform. At that time, the forum did not require a real-name system, and the management was not strict. As such, Han Kuan only needed to randomly start a conversation, and a large group of people would provide him with clues.
However, the situation had changed with the passage of time. After so many years, those data could no longer be found. Moreover, even if they could find Han Kuan's chat history, it would not be of any use.
Therefore, although the direction of the investigation was very clear, all the evidence that Zhao Yu and the others had obtained was soft evidence, which was invalid.
If they wanted to prove Han Kuan's guilt, they had to find more concrete evidence. However, Zhao Yu had been opening hexagrams for the past few days, but he still hadn't gotten a Gen hexagram. Is the Devil Case really an unsolved case?
No!
Zhao Yu's answer was firm.
