Gu Huaiyi's face became serious.

"Tell me in detail what you think."

Yun Hua nodded, "You also said the two cases in the first two cases. The two cases actually have one thing in common, and the most coincidental thing is that the two victims know each other. This is actually enough to connect the two cases. After all, there are not so many coincidences in the world. What you don't believe in the most when handling cases is coincidences."

Gu Huai nodded and signaled Yunhua to continue.

Yunhua drank a sip of water: "Actually, I believe that you have combined these two cases privately, not just because the two victims know this common point."

"What else?"

"There are also things that these two cases show." Yun Hua said, "The victims in these two cases were tortured to death by an extreme way. From these two cases, it can be seen that the murderer is extremely hated to the victim. The hatred of the murderer is so great that he cannot vent his anger by simply killing them. Only by killing them simply can he use this kind of murder. Of course, there is another possibility that the murderer is a murderer, and only such murder can excite him. But I don't think it would be the reason."

"Why?"

"Because there is no data support! Judging from the victims' situation, the murderers' methods are very mature and have strong anti-reconnaissance capabilities. It is impossible for the murderers to have such meticulous means as soon as they commit the crime for the first time. Like serial killers, they will continue to escalate, and their killing methods will become more perfect." Yun Hua said, "Although some people in society keep making serial killers mysterious and even myths, serial killers are not as powerful as people imagine."

Yun Hua said calmly, "In fact, most serial killers are psychologically morbid, which may be psychologically morbid caused by acquired environments, or psychologically morbid caused by innate physiological defects. To put it bluntly, they are mentally ill. They cannot have the same emotions as ordinary people in many things. Only killing and violence can make their emotions fluctuate and make them feel excited."

"Research shows that serial killers' killing methods will continue to upgrade, but as they continue to upgrade and the frequency of killing continues to increase, it means that serial killers are losing control and they can no longer control their killing heart. Later, they will lose their minds and become crazy. This can be reflected in their methods of committing crimes."

Yun Hua said, "But looking at the two cases in the previous ones, the murderer's technique is very steady and sophisticated, and he has no feeling of panic at all. Judging from your investigation records, the murderer really has no valuable clues, which shows that the murderer's mind is still very meticulous and his behavior is not confusing at all."

"What else?" Gu Huaiyi looked at her.

"Also, suppose the murderer is a serial killer with high IQ, and he is a pleasure to kill people, and he can control his behavior. First of all, there are very few killers. Because killing will make the murderer feel excited. At the beginning, this excitement may be satisfying by killing one person a year, but gradually, killing one person a year cannot satisfy them. They will kill one person in half a year, then evolve to kill one person in March, kill one person in a month, and kill one person a week..."

"This kind of evolution is the sign of the collapse of serial killers."

"Now, assuming that the other party is a high IQ and a strong anti-reconnaissance tyrant, killing is a fun and a game of fighting wits and courage with the police. He will clear out all his traces, display his works to the police, and play with the police." Yun Hua said, "But if the murderer is such a person, he will never kill people every week to provoke the police! If this kind of person kills people, they will never put themselves in danger!"

Gu Huai nodded, "So you ruled out that the murderer is a serial killer with escalating behavior, and also ruled out that the murderer is a high-IQ torture killer."

Yunhua's eyes were still on the computer screen, and she nodded, "Yes, I ruled out these two possibilities, so there is only one possibility left."

"Venocide. The murderer has a grudge with these two people, and it is a very deep grudge. Generally, no matter how big the grudge is, it will be eliminated if you kill someone. But for the murderer, even if you kill the victim, it will not be able to relieve the hatred in his heart, so there will be the next torture."

Gu Huaiyi smiled: "You are right, we analyzed it in private. These two cases are not like ordinary serial killers, but more like hatred killing. This is also the reason why we really merged the case. We judged that the murderer knew the two deceased and had a deep hatred with the two deceased. However, we carefully investigated the social relationship between the two deceased and found no suspicious people."

Yunhua was silent.

Gu Huaiyi said again, "It is obvious that the murderer's hatred for the deceased is very deep. But the case of Tan Shaoning and Ruan Mumu is a murderer. Although the injuries on Ruan Mumu are also very serious, it can be seen that the injuries were left when they were bullied, which is different from the injuries left by the deceased in the previous two cases. Moreover, the nature of the murder is also different from the nature of the two cases in the previous two cases. The first two cases can be combined, but the case of Shaoning and Ruan Mumu is really incompatible with each other."

Yun Hua looked at Gu Huaiyi, "Not necessarily."

"Why?"

"I said that I don't believe that Tan Shaoning will kill Ruan Mumu, and I don't believe that he will kill Ruan Mumu. Then there must be another murderer in Ruan Mumu's death." Yun Hua looked at Gu Huaiyi calmly, "You think the nature of the case is different because you limited Tan Shaoning's case to a murder case. Due to the conclusive evidence, you put Tan Shaoning in the position of killing Ruan Mumu's murderer, and this case is really completely different from the previous two cases!"

Yun Hua said: "But from my perspective, I don't believe that Tan Shaoning is the murderer, and the deceased Ruan Mumu will definitely not be the murderer, so there must be another murderer!"

Gu Huai frowned.

Just then, the office door was pushed open and someone walked in.

"I agree with what Yunhua said."

Yunhua quickly looked up and laughed: "Brother Beiqian, why are you here? When did you come?"

Gu Huaiyi said, "Because of talking about Shaoning, you cannot participate in this case. In addition, this series of cases is very bizarre, so I reported to the bureau and asked Beiqian to come and help."

Gu Huai smiled, "When you ruled out that those two cases were done by serial killers before, I wanted to laugh because your judgment was exactly the same as Beiqian's, and even the reasons were the same. But Beiqian said it a little simpler than yours, and it was a summary speech."

Yun Hua was helpless, "Brother Beiqian is a professional, how can I compare with him?"

"It's okay to draw a conclusion. It doesn't matter whether the language organization is simple or complex." Zhou Sheng Beiqian walked over with a smile and said, "I also agree with Yun Hua's judgment. When talking about the Shaoning Ruan Mumu case, there should be another murderer, and this murderer also hated the two of them."

"Then why didn't they be killed?" Gu Huai asked.

Zhou Sheng Beiqian pursed his lips, but did not answer, but looked at Yun Hua.

Yun Hua bit her lip, "Because...the murderer believes that doing so is the best way to vent his anger."

Gu Huaiyi was a little surprised.

After a moment, he looked at Zhou Sheng Beiqian, "Do you think so too?"

Zhou Shengbeiqian nodded.

Gu Huai took a deep breath, "What you mean is that now we should investigate the three cases together and find a murderer. He hated Tan Shaoning Ruan Mumu and the other two suspects, so he deliberately designed to kill them one by one..."

Gu Huaiyi rubbed his eyebrows, "To be honest, the pressure on the previous two cases is very great. We carefully sorted out the social relationship between the two victims. Anyone who can get involved with them at the same time and have had a dispute with them, we investigated them all, but found nothing. Not to mention that now, Ruan Mumu and Tan Shaoning are added..."

"I will ask someone to continue to investigate, but I can almost tell the results of the investigation now and I will definitely find nothing. If there were such a person who had such a deep hatred relationship with these people at the same time, we would have dug up the people long ago."

Yunhua was silent for a while and whispered: "I just said one direction."

"I know, I will pay attention to this point. If I can't check it once, I will continue to check it again. If there is really such a person, he will sooner or later show his strength!" Gu Huai said.

As he said that, Gu Huaiyi looked at Yun Hua again, "I think, if you can let Tan Shaoning speak, maybe things will be much simpler. I can't understand. If it wasn't Tan Shaoning, why would he admit that he killed Ruan Mumu? If he didn't do it, why would he find the sperm spots belonging to Tan Shaoning in Ruan Mumu's body when he was taking the autopsy for Ruan Mumu?"

Yun Hua looked at Gu Huaiyi, "Have you forgotten the man's case?"

"Ah? What's wrong with the man-pier case?"

"In the case of a man, the murderer used the deceased's stomp plant to penetrate the deceased's own anus. What does this look like?" Yun Hua asked.

Gu Huaiyi pursed his lips.

Without waiting for Gu Huaiyi to answer, Yun Hua said, "Does such abuse seem to let the deceased ** themselves?"

"hiss--"

Gu Huaiyi gasped, "I originally thought...that this was a part of the abuse, but if I look at it like this, let the deceased ** himself, it's really..."
