At eight o'clock in the evening of December 29, the female corpse found in the elm forest has been confirmed to be Sun Qili. When Liu Lujin handed the autopsy report to Bi Guofeng, they invariably glanced at each other. Bi Guofeng remembered Liu Lujin's reasoning that the murderer was likely to continue to commit crimes a few days ago. If the murderer of Sun Qili and the murderer of Zhou Xi are the same person, from the perspective of modus operandi, there is no doubt that the murderer has become more cold-blooded and cruel than before. Although Bi Guofeng discovered the first crime scene with his own intuition, he did not find any valuable clues in Sun Qili's home. Instead, he was confused by the murderer.

"Professor Liu, why did you say that the murderer moved the body to the elm forest after killing Sun Qili this time?" Bi Guofeng walked around uneasily in the underground laboratory.

"Don't walk around, it gives me a headache." Liu Lujin said dissatisfiedly, "Do you want coffee or tea?" ”

"Coffee bar."

"Coffee is only instant."

Bi Guofeng raised his eyes and glanced at Liu Lujin: "Why is there only instant one, why don't I go and get you the coffee I drink." ”

Liu Lujin grabbed Bi Guofeng after hearing this, and said coldly: "It's not that I said you, your temper is really not suitable for being a criminal policeman, it's too impetuous." ”

Bi Guofeng's face turned crimson when he heard this, and he said after a while: "Why am I not suitable, didn't I find out at the scene of the first murder this time?" If you do everything according to the rules, then how can you ......?"

"Enough!" Liu Lujin interrupted Bi Guofeng violently. "It's good that you have your own measure, and I won't say anything more."

It was the first time that Bi Guofeng saw Liu Lujin angry, and couldn't help but be stunned. He scratched his hair and said, "I think you want to talk about my punching hole." ”

"One yard is one yard, I don't like that guy Conde, but it's still your fault with this beating."

Bi Guofeng was overjoyed when he heard this: "You also think I'm very relieved, right?" That guy looks like a criminal policeman with a big belly, but I think it's more like a high-ranking official, and the bureau should have transferred him to the Political Department a long time ago. ”

"Enough is enough, let's talk about the case. Why did you say the murderer moved Sun Qili's body? ”

Bi Guofeng said: "To be honest, I really can't figure this out. I have observed Sun Qili's home, there are several wardrobes in her house that are more than one person high, and it is absolutely more than enough to hide the corpse, and it is absolutely impossible for the murderer not to find this, but why go far? ”

"If you can guess the murderer's intentions, then you are also a pervert. I speculate that the murderer may have done this to delay the discovery of the body, but we can't tell how long it will be delayed, whether it will never be found, or whether it will not be found for a while. Liu Lujin stuffed a cup of instant coffee into Bi Guofeng's hand, and then found a chair to sit in.

"Naturally, it will never be found, and if the body is found, doesn't that increase the chances of the murderer being caught?"

"You're saying that too absolutely. As long as the corpse decomposes to a certain extent, it will not actually play much role in arresting the murderer. Valuable evidence will be destroyed over time. So the murderer doesn't have to let the body never be found, he just needs to make sure that by the time the body is found, the body is no longer able to provide evidence to solve the case. ”

Bi Guofeng nodded seriously after hearing this: "Then you mean that the murderer didn't think to completely cover up the fact that Sun Qili was dead." Whether or not we find the body is not a threat to him, is it? ”

"That's right, but ......"

"However, before the body could decompose, we found it." Bi Guofeng said, "And why did the murderer expose his body when he buried it?" Isn't this the place where there are three hundred taels of silver? From the point of view of us ordinary people, if we want to dig a pit to bury people, it must be to dig a rectangle so that people can lie in it. It's a lot of work to dig a circular pit, and it's so unreasonable. ”

"You're on the point, it's really strange that the murderer dug a pit like that. But even if the victim was allowed to sit cross-legged in the pit, there was plenty of space, and if the murderer lowered the head of the deceased to his chest, he would not expose the head of the body when he was finally buried. The murderer deliberately exposed the victim's head, which must have been purposeful. ”

"Purpose, purpose...... What purpose can this be? Such behavior is fundamentally antilogical. Since the murderer removed the body, he must have done so to prevent us from discovering it. But when I buried it, I was so sloppy......"

"Do you think it could be that when the murderer was burying the body, someone suddenly came, and he had to give up burying the body and choose to run away in a hurry?"

"But in that case, there should be eyewitnesses, right?"

"Maybe the murderer didn't see it and ran away......"

"Perhaps...... Your words are too ......" Bi Guofeng began to get irritable again, "Tsk, I don't understand......"

"It's a little tricky."

"Professor, what do you think the murderer's motive for premeditating to kill Sun Qili this time? The autopsy report showed that the deceased had not been sexually assaulted, and only had scars on his face and neck, which was somewhat different from Zhou's. This murder incident makes me think that the murderer went straight to this 'killing'. From the time the killer meets the victim to the time the victim is killed, the process should be very short. ”

Liu Lujin looked at Bi Guofeng and shook his head, this junior in front of him who likes to speculate makes his head not ordinarily big. From what he has learned, any speculation must be based on facts. What are the facts? Facts are evidence. No speculation can hold up without evidence. Liu Lujin has been a forensic doctor for almost 20 years, and he knows that solving cases does require some imagination, but these imaginations also need to be compensated by evidence and bound by law. It's not like sitting in a chair and just thinking about it can solve a case.

Liu Lujin asked Bi Guofeng: "Why do you think that the murderer is not a murder of passion, but a premeditated murder?" ”

"Professor Liu, don't you think so?"

Liu Lujin said: "I think it is more likely that it is a murder of passion." Look at Sun Qili's home, there are two bowls of sweet soup on the table in the living room, obviously the murderer and Sun Qili know each other, so they will bring sweet soup to entertain the murderer. In other words, when Sun Qili and the deceased first met, the relationship between the two was at least friendly and free of hostility. Therefore, I judged that the murderer's murderous intent should be a momentary thing, not a premeditated murder. ”

"After Zhou Xi's case, if you say ...... I mean, if! Bi Guofeng was afraid that Liu Lujin would say that he was rash, so he hurriedly added, "If the murderer of Sun Qili and the murderer of Zhou Xi this time are the same person, do you feel that the murderer is deliberately conveying something to us." ”

"Why?"

"Think about it, in Zhou Xi's case, the murderer took Zhou Xi's clothes and left a kiss mark on her neck. From these clues, we can find that the murderer is most likely a pervert. And this time, after killing Sun Qili, although the murderer moved the body, he did not bury Sun Qili. This not only violates the murderer's intention to cover up the murder, but also violates the murderer's psychology that he wants to leave the scene as soon as possible after the killing. The logic of the murderer's behavior seems to me to be confused, but can a human really do such an unreasonable behavior? Even if he's a perverted murderer. I think the murderer is trying to tell us something in some way, and as for what it is, we just didn't find out for a while. ”

"There is no such thing as incomprehensible logic in this world, and if we really want to say what the murderer wants to convey to us, I think there is only one thing, and that is the sense of ceremony."

"Ritual?"

Bi Guofeng suddenly chuckled in his heart when he heard this, this was the last word he wanted to hear. Because, no one can know what the murderer will want to convey through this ritual.

Bi Guofeng sighed, walked to the sink to wash his hands, poured another cup of coffee, and then said: "Let's not say that this ceremony is not ritualistic, this can't even be directly proved through evidence." Professor Liu, we still have something we can't explain. ”

"Tell me about it."

"How did the murderer get the body into the woods?"

Liu Lujin glanced at Bi Guofeng strangely and said: "The forest where the crime occurred and the victim's home are only less than half a kilometer apart, whether the murderer was improvised or premeditated, since he thought of carrying the body, he must have prepared a car or other means of transportation in advance." ”

Bi Guofeng hurriedly waved his hand and said, "No, no, no, this time you are wrong, this is a place that I can't figure out." Between the victim's home and the woods, there was a construction site. If the killer wanted to move the body into the woods, he had to pass through that construction site. But no matter what means of transportation the killer used to carry the body, it would be seen by the workers at the construction site. ”

"What about seeing? Workers at the construction site couldn't have made a deep impression of a passing car, unless the killer was stupid enough to use the back compartment and tie the body to the roof. Liu Lujin listened to Bi Guofeng's words and asked with interest.

Bi Guofeng said: "I didn't mean that, Professor Liu, do you remember that the place where the body was buried was only a dozen meters away from the road outside the woods?" ”

"Of course I do."

"The time of Sun Qili's death was between 3 and 4 p.m. on the 28th, but that time period happened to be the time when the residents of the residential building got off work. To get into a residential building, everyone has to go through that road and that construction site. As you said, the murderer drove past the construction site without arousing the suspicion of the workers. But when the killer drove to the vicinity of the woods where the body was buried, where should his car stop? If the murderer's vehicle had been parked on the side of the road, the residents who had been returning home on the highway that afternoon would have seen it. But as far as I can see, no one has noticed any suspicious vehicles on the side of the road. ”

"This ......," Liu Lujin fell into deep thought. As Bi Guofeng said, if the murderer used the car to carry the body, where would the car stop? It was absolutely impossible in the woods, the elm trees were not spaced enough for a car to pass, and the road outside the woods happened to be the only way for residents to come back from work. There is also a construction site on the only road between the residential buildings and the woods, and if nothing else, this is also a factor that cannot be bypassed. In other words, a complete closed loop was formed between the murder scene and the burial site, turning into a surveillance chamber.

"Is there such a possibility, the murderer did not remove the body immediately after killing Sun Qili on the afternoon of the 28th, but waited at the scene of the crime until late at night. In the dead of night, the residents of the residential buildings have fallen asleep, and the workers on the construction site have already left work. It was only then that the murderer quietly left Sun Qili's house with the body and went to the woods to bury the body. This also complements what happened in the more than ten hours when the body was removed and found, in the middle of the blank. ”

Bi Guofeng listened to Liu Lujin's speculation and put forward a rebuttal without thinking much: "If this is the case, the murderer must know in advance that the residents of the residential building happened to be returning from work at the time when he killed them, otherwise he would not have chosen to stay at the scene of the crime until late at night in order to avoid them." ”

"No, in fact, the murderer is not trying to avoid the residents who have returned from work."

"What do you mean by that?"

"If the murderer really waited at the scene of the crime late at night, there was only one reason. That was to wait for all the workers at the construction site to come home from work. Liu Lujin said.

"Are you saying that the murderer made a mistake and happened to avoid the residents who came back from work while avoiding the workers at the construction site?"

Liu Lujin nodded: "On the afternoon of the 28th, after the murderer entered the Banshan Village, he would see the construction site at first sight. After killing Sun Qili, the murderer came up with the idea of removing the body. If you were a murderer, what would be the first thing that would come to your mind? ”

"If you say that, you'll think of that site right away." Bi Guofeng nodded, "In other words, the murderer doesn't know what time the residents there will come back from work." ”

"It should be like this, if you think about it, where most people get off work before 4 o'clock, my grandson's elementary school doesn't end so early, let alone work. If the murderer had expected this in advance, it would not make sense. ”

"So, we can now determine how the murderer was able to remove the body through this so-called surveillance room." Bi Guofeng touched the stubble on his chin, "What do you think about the other secret room?" The doors and windows of Sun Qili's house were locked from the inside, so how did the body leave the scene of the first crime? ”

Liu Lujin shook his head, "To be honest, I haven't seen any cases over the years, but it's the first time I've seen such a strange case like the one in front of me." Judging from the traces at the scene, there is no doubt that Sun Qili's house was the first crime scene, but since the body was removed from there, it is unlikely that the doors and windows will be locked from the inside. It's not logically possible to ......"

"But I was the first to walk in that day, and the door was locked, and the landlord tried, and I tried, and there was no way there was anything going on in that simple old lock, and the latches and chains on the door were indeed locked. It all happened for real......"

"When you entered the house that day, did you really check all the doors and windows, and they were all locked?" Liu Lujin was skeptical.

"I can't look away, there are only four windows in the scene, one in the living room, one in the bedroom, one in the kitchen, and one in the toilet. We are now at least sure that the gate to the scene was absolutely locked from the inside, and that no matter what trick the killer used, it was absolutely impossible for him to leave the gate with the body and then lock the door from the inside. ”

Liu Lujin said: "Then you say, could the murderer lock the door after killing Sun Qili at the scene, and then leave through any of the other four windows with the body." ”

"If that's the case, when I enter the site, one of the other four windows on the site must be open. Otherwise, how could the murderer leave the scene and at the same time close and lock the windows from the outside? ”

Bi Guofeng was confused for a while: "All this is too illogical, no matter who locks the doors and windows in Sun Qili's home, he can't disappear out of thin air in the end." ”

Liu Lujin glanced at Bi Guofeng: "Do you know the logic now?" ”

Bi Guofeng smiled awkwardly: "Do you think the world really needs supernatural powers?" ”

Liu Lujin sighed secretly when he heard this, if every unsolvable case was blamed on gods and ghosts, it would be too disrespectful to the deceased.

Bi Guofeng took out the pack of Lianhe cigarettes that Hao Liye gave him from his arms, and took out one and put it in his mouth. When Liu Lu saw it, he quickly snatched the cigarette from his mouth and said, "This is a laboratory, what do you want?" ”

Bi Guofeng was stunned for a moment, and then suddenly remembered where he was. He peeked at Liu Lujin and said, "By the way, did I tell you that I encountered some strange things when I was investigating in that residential area." ”

Liu Lujin took the cigarette he snatched from Bi Guofeng's mouth, put it under his nose and sniffed it, and then licked his mouth. He looked at Bi Guofeng strangely and said, "Strange thing? Are we experiencing fewer strange things now? ”

"I always think that people there always look at me strangely, and no matter what I ask them, they say they don't know, which is not logical. Usually when I ask those middle-aged women, they are eager to talk to me more, whether they have or not, they will talk to me endlessly. Do you think there's something greasy in this? ”

"Isn't this case the case in charge of Comte? How did you get involved? If you want me to say that the residents must have been instructed by the landlord not to talk too much in front of you. If you ask, it will definitely be much better to go at a time when the landlord is not there. Liu Lu said with a smile.

Bi Guofeng pondered in his heart, yesterday's attitude towards the landlady was indeed likely to make the other party vigilant. I thought: If necessary, I have to go again.

Bi Guofeng clasped his hands together and rubbed his face vigorously, these two cases can be said to have exhausted him. After discussing with Liu Lujin for so long, I thought that I had finally found some clues, but in the end, it still fell short. Ten minutes later, Bi Guofeng said goodbye to Liu Lujin and left the underground laboratory. The cigarette tickled at his throat so much that he had to go outside and light one first.

Bi Guofeng glanced at the time on his mobile phone, it was now close to the early hours of the morning, and in addition to his colleagues who worked the night shift in the bureau, only Kong De and his group were still in a meeting all night. Although Bi Guofeng helped a lot in Sun Qili's case this time, Kong De did not mean to let him intervene. In addition to being able to learn about the progress of some cases, he has been largely excluded from the investigation.

Bi Guofeng knew that Kong De was about to be promoted and urgently needed a meritorious performance, so he had no choice but to stand by and watch. After discussing with Liu Lujin, Bi Guofeng already had the idea of investigating Sun Qili's case and Zhou Xi's case together. However, due to the hindrance of his relationship with Conde, Bi Guofeng could not put such an idea into practice.

In the dead of night, Bi Guofeng inexplicably remembered Cen Min again. At first, Bi Guofeng was still startled by this thought, he suddenly remembered the day he interrogated Zhang Xian, and he also remembered Cen Min, but it was in the morning. How do you feel about her? Bi Guofeng's mind was chaotic, and he didn't know if it was the dizziness caused by cigarettes, or if he really had some special feelings for Cen Min.

Bi Guofeng still remembers the words he said to Cen Min when he called her. He always had a strange feeling, was Cen Min really the real victim in the August 12 case? Why can you survive such a case and still act like a normal person? Bi Guofeng felt a chill in his heart, why didn't Cen Min call 120 when his mother fell in a pool of blood? If the ambulance had arrived in time, his mother might have survived.

Now, the murderer of his mother has been at large for more than 20 years, and Bi Guofeng has gradually stopped believing in the words of Skynet's restoration and negligence. He thinks that there are people in this world who have never appeared in your life, but they can also destroy your life. Bi Guofeng still remembers the appearance of his mother's body: pale and cold, and he silently vowed to become a criminal policeman at that time. Not only does he have to catch the bastard who killed his mother, but he also has to catch all the criminals in the world.

But now, not only did he not catch the murderer, but he couldn't even catch a clue about the two murders in front of him. Bi Guofeng felt that he had fallen into a trap of self-doubt, while the murderers who were at large laughed at him from afar.
