At around 7 o'clock in the morning, Gu Song and Xia Shi yawned and came to the restaurant on the first floor for breakfast. Halfway when she met Qi Ruonan, she also had dark circles under her eyes, and her spirit was slightly sluggish, it seemed that after listening to Gu Song's "confession", after returning to her room, she didn't rest well.

Gu Song slept intermittently for more than three hours, although he was exhausted by the terrifying nightmare, it was still better than the summer time when he had insomnia all night.

When the alarm clock rang, Xia Shi almost maintained Gu Song's posture before falling asleep, sitting by the window and smoking silently. If Gu Song hadn't snatched the cigarette butt from his hand and reminded him that it was time to wash up and have breakfast, he would probably have stayed there all day.

The three of them walked over to an empty table with a breakfast buffet and sat down.

Qiao Sheng saw them not far away, and sat with them with his plate. Seeing these people listless and sleepy-eyed, he couldn't help frowning and turned on the preaching mode. "Didn't I tell you to hurry up and get some rest? Today's task is very heavy, how do you work in this state? How to solve the case? Don't forget, you are now representing the image of the city bureau, don't embarrass me. ”

As soon as Qiao Sheng's words fell, Xia Shi sneered on the side and said: "Haven't some people already disgraced us, in front of so many colleagues, they vomited miserably at the scene of the crime, it makes people wonder if he is a newcomer......"

Gu Song knew that Xia Shi was still holding back a breath of anger in his heart because of Xinlei's matter, so he didn't answer his words and continued to eat. However, Qi Ruonan said with some grievances: "Brother Xia Shi, don't be sarcastic about him, Senior Brother has experienced that kind of thing, and he is also very pitiful." ”

"Huh, he's pitiful?" Xia Shi glanced at Gu Song and said coldly, "Xinlei is pitiful when she was harmed like that by him." ”

"That's right, Sister Xinlei is really pitiful, but Senior Brother didn't mean it. How did he know that he would encounter such a horrific murder in the public toilet that night? ”

"According to me, he shouldn't have taken Xinlei to a hellish place like that. What detective to investigate the truth and think of yourself as Sherlock Holmes? "The more Xia Shi talked, the more angry he became, and at the same time he was a little scared in his heart." Now that I think about it, if the time was unfortunate that day, Xinlei might have met that perverted murderer in the toilet, and maybe the victim of that night would have been her. ”

"How is that possible?" Gu Song put down his chopsticks with a snap, glared at Xia Shi angrily and said, "I was waiting outside, if I really met the murderer, I would definitely subdue him as soon as possible, how could I let Xinlei be hurt by the murderer?" ”

"That's not easy to say, what if the murderer moves too fast and you don't have time to save her?"

"I ......"

"Wait." Qiao Sheng interrupted their conversation, "How many of you are talking about that case from five years ago?" He looked at Gu Song and asked, "Did you tell them the truth?" ”

"Hmm." Gu Song shrugged his shoulders helplessly, "Even if I don't say it, they will find out soon." ”

At 8 o'clock in the morning, the case analysis meeting was held on time in the No. 1 conference room of the county public security bureau. Director Xie, who rushed back from other places early in the morning, came directly to the meeting without even bothering to eat breakfast.

Dr. Chen and two aides performed an autopsy on the victim's body overnight and confirmed that the killer's modus operandi was the same as the one five years earlier. Since most of the participants did not know much about the case from five years ago, Dr. Chen gave a detailed introduction to the case when he reported on the autopsy.

When mentioning the discovery of the corpse, Forensic Doctor Chen and Zhao Hongshan both set their eyes on Gu Song. The latter's mood has calmed down and calmed down a lot compared to last night, and I believe that after a night of relaxation, he has been able to face all this calmly.

From the analysis of the murderer's unique modus operandi, the murderer obviously has a certain understanding of human body structure and anatomy, and his shots are very accurate, and the intestines pulled out of the abdominal cavity are clean and neat, and they will never be done by mistake.

In the first case, the killer strangled the victim to death with a rope, then dragged the victim's intestines out of the body from the lower body and wrapped them around the victim's neck. And in last night's case, instead of continuing the previous way, the killer hit the victim with a stone in the back of the head, causing him to faint, and then committed a brutal atrocity against the victim. In other words, the fact that the victim was still alive when the murderer pulled out the victim's intestines makes people shudder to think about it.

Although the murderer subdued the victim in different ways comparing the two cases, this brutal and special modus operandi is difficult to imitate, so it can basically be concluded that the two cases were committed by the same murderer and should be immediately investigated.

Five years ago, when the special case team was investigating the "June 18 Murder Case", it speculated that the murderer may have a background in medicine, anatomy, and other related knowledge, and had experienced major changes in his life or work, which caused his psychological abnormalities. Dr. Chen still adheres to the above point of view, because from a professional point of view, it is absolutely impossible for a "layman" who does not have the relevant knowledge background to complete the work of removing the small intestine from the lower body in such a short time.

After listening to Forensic Doctor Chen's narration, Qiao Sheng added: "Assuming that the murderer is a psychopathic murderer with a psychological abnormality as we speculated, why did he disappear after committing that murder in R City five years ago, and now he suddenly runs out to kill people?" In the past five years, did he stop doing it? Or did they commit crimes elsewhere and go undetected? Although the second scenario is very unlikely, we need to investigate it as soon as possible.

"Now let's focus on the first case. If the murderer did not commit a crime in these five years, what caused him to stop quickly after the first crime, and what caused him to kill again? ”

"The reason why the murderer stopped may be subjective or objective." Xia Shi tried to analyze, "If it is said that five years ago, the murderer was killed by such brutal means to vent his anger (venting his desire) because he experienced a major accident, which caused him to have a psychological abnormality. Perhaps after psychological treatment, or through the companionship and guidance of his family, he temporarily controlled his desire to kill. But in recent times, his life has changed again, upsetting his mental balance and causing him to lose control again.

"Another possibility is that the murderer was unable to come out to commit the crime during the five years due to physical health reasons (such as illness) or because of limited mobility (such as imprisonment), until recently he was able to commit the crime."

Gu Song continued Xia Shi's words: "I think it is very possible that the murderer's health will change. Think of the case five years ago, where the killer strangled the victim to death with a rope, and subduing the victim in this way was a long and physically demanding process. Five years later, the disappeared murderer reappeared, and instead of using the previous uniform method, he chose to sneak up on the victim from behind with a stone, making him lose the ability to resist, indicating that the murderer may not be as confident in his physical strength as before, and had to change his strategy. ”

"It's a possibility." Zhao Hongshan cast an approving glance at Gu Song and Xia Shi, feeling that these two young people were really as Qiao Sheng said, open-minded and quick-thinking, and they were both rare talents. "It's just that we haven't mastered the physical characteristics of the murderer yet, and it is still difficult to find the murderer by relying on these psychological analyses."

Qiao Sheng nodded: "So the top priority is to continue to visit the people around the crime scene to find witnesses." Only by knowing the height, weight, age and other information of the murderer can we effectively narrow down the scope of investigation by combining the characteristics of the murderer. In addition......" Qiao Sheng thought for a moment and continued to add, "Although this possibility is almost zero, but to be on the safe side, we should still investigate the relationship between the two victims and see if they have any common connections." ”

After Qiao Sheng finished speaking, he looked at Director Xie, who had not spoken for a long time, with an inquiring gaze. After working in the Municipal Bureau for so many years, he has cooperated with Director Xie many times, and knows that the other party is also a master of criminal investigation. Unexpectedly, the other party smiled at him modestly and said: "You know these two cases more thoroughly than me, and you will arrange all the work this time." I will give you the best support in terms of people and technology. It is hoped that through our joint efforts, the murderer can be apprehended as soon as possible and his crime can be stopped. ”

"Okay, then I'll be respectful and obey." Qiao Sheng replied. Subsequently, he arranged the next few tasks to be focused on:

1. Find out whether there were similar casualties in R City and its surrounding areas from 2011 to 2016, and whether there were any cases of concealment of the case and failure to report it in a timely manner.

2. Seize the time to visit the people around the crime scene to find witnesses; Surveillance footage near the crime scene was retrieved to look for suspicious persons.

3. Investigate whether there is a connection between the two victims.

4. On the basis of the analysis of five years ago, further characterize the psychological characteristics of criminal suspects and improve the list of suspects; Focus on screening people who have suffered from serious illnesses or accidents that have affected their health in the past five years; Screening of people who were imprisoned five years ago and recently released from prison after completing their sentences......

5. Let the media issue notices to remind women to pay attention to their personal safety, and try not to go in and out of remote public restrooms alone at night to prevent the next case from happening......

After the meeting ended, Director Xie left Qiao Sheng and Zhao Hongshan to talk, and the others received their respective tasks and began to get busy.

Gu Song and Xia Shi were also arranged to visit near the scene of the crime. However, walking out of the county bureau office building, Gu Song suddenly remembered an important matter, and hurriedly said to Xia Shi: "Eh, let's go to the police station and ask about the pervert." ”

"What pervert?" I haven't slept all night in the summer, and my brain is already a little out of the way.

"You're such a noble person who forgets things." Gu Song raised his eyebrows when he was in the summer, "Didn't the owner of the barbecue restaurant say that the public toilet where the murder occurred is often infested with perverts." The murderer should have stepped on the spot nearby before committing the crime, in case ......"

"Oh, that's what you say." Xia Shi patted his cheeks vigorously with both hands, trying to sober himself up. He remembered that Xin Lei, who was involved in the case and was still lying in a mental hospital, had a heavy sense of mission.
