"If there are outsiders disturbing during the decomposition process, it can't be completed at all, so the suspect should be single, and the worst is that he is a migrant worker living alone in Songhai City."

"Secondly, the psychological quality of the suspect is excellent, and he is usually used to seeing bloody things, which corroborates the profession I just mentioned. In addition, I have the following speculations about the murderer's motive for committing the crime, the first possibility is that the prisoner has a certain chance of committing a criminal record, which can be inferred from the means of dismembering the body, and the motive for the crime includes the elements of revenge against society and challenging the legal status. I remember that a few years ago there was a case in Yunnan, where the criminal suspect Zhang Min'an was sentenced to seven years for theft, and after he was released from prison, he committed several murders one after another, and the victims had no contact with each other, which caused great confusion in the work of solving the case. In the end, because of his negligence after committing the crime, he did not kill the person completely, and was rescued by the police who came later. In the end, the case was solved according to the survivor's account, and when he was arraigned afterwards, his reason was to take revenge on society. ”

Li Jun nodded slightly, and after recording it on the paper, he motioned for him to continue.

"The second possibility is just the opposite of what I just said, the use of the practice of decomposing the corpse can not fully reflect the murderer's personality perversion, but can only reflect that the murderer is thoughtful, highly educated or has a good professional background, and has the ability to judge the behavior of the police investigation, so the murderer tries to destroy the evidence that may expose himself, and does not mean that the murderer is psychopathic, especially cannot indicate that the murderer has hatred for the victim: killing a person is already the greatest "revenge", Is it still necessary to shredded the corpses? The purpose of dismembering the corpse is entirely for the purpose of destroying the evidence, including the convenience of identifying, throwing the body, and concealing it, especially the convenience of carrying and disposing the body separately, and the distance of the body dumping site has proved the intention of decomposing the body. Generally speaking, only people with a higher "level" have such thinking skills. ”

"Whether it is Songhua Street in the east of the city or Huangpu Road in Jinghai District, these two places belong to the downtown area and are not far away, and the murderer decomposed the body into more than 2,000 pieces is likely to be for the convenience of throwing the body, and under such a premise, there is only one situation, the murderer has no convenient means of transportation, such as a car, may only have a bicycle, or even any means of transportation."

"If there is a vehicle that can accommodate the whole body or can be loaded and transported at one time after being divided, there is no need for the murderer to throw the body in such a noisy urban area in the east of the city, and he will not take greater risks to throw the body in different places many times: every time the act of throwing the body increases, it increases the risk of being discovered, since the murderer can make the decision to divide the body, it means that the murderer has considered the risk enough, if the murderer has a vehicle, he will definitely drive the car to a farther and more hidden place to deal with it, How can it be in an urban area with many people? ”

Therefore, the murderer definitely did not have a car or other vehicles. The whole process of throwing the corpse should be a pattern of starting from the scene of dismemberment and abandoning a part of the body each time, and bringing out the abandonment from the scene many times. Therefore, the scene of the murder was definitely near the area where the bodies were dumped, and the vehicles used to dump the bodies were definitely silent bicycles. Because motor vehicles make sounds that are sure to attract attention, bicycles are the most convenient and safe. At the same time, I guess the time of throwing the body should be in the early morning or second half of the night on July 13th. It rained heavily in Songhai City last night, and there were few pedestrians on the road, so we had the basic conditions for throwing corpses. ”

"The above are some of my existing judgments, which can only be said to be an idea and cannot be used as evidence, after all, there is no evidence to support it."

After Sun Jianguo finished speaking, he lit a cigarette, frowning and spitting clouds and mist, not knowing what he was thinking.

After listening to Sun Jianguo's reasoning, I almost didn't applaud, just relying on the broken corpses found at the scene, I can deduce so much information about the murderer, which is worthy of being an old-timer who has worked for more than ten years. Before, I thought that with my identity as a top student, it was not easy to handle cases at the grassroots level, but I didn't expect that I had no idea at all about the first big case I encountered, but someone could deduce so many clues.

"Very good, I personally don't feel that there is anything wrong with Lao Sun's thinking, many places are the same as I think, do other people have different opinions?" After Li Jun briefly recorded it, he looked around again and asked.

At this time, I remembered what Ma Zhiyuan told me just now, and hurriedly stood up and said: "Team Li, just now Brother Xiao Ma told me a piece of news that after the murderer killed the victim, he put the body in the refrigerator and refrigerated it, and then took it out to decompose and boil it. Lactic acid is excreted during the freezing process, so it is impossible to determine the time of death of the victim from the existing human tissue. There are also most of the meat slices that are 2*1*0.1cm, which is very standard, and they are divided according to the texture of human muscles. ”

Zhang Bin, who had been sitting without speaking, slapped his thigh after hearing this, and exclaimed: "Sure enough, when I was sorting out the black plastic bag before, I felt that some pieces of meat seemed to have traces of frostbite, although most of them were cooked, they could still be distinguished from some subtle places on the skull." ”

Then he looked at Li Jun again: "Team Li, I'm afraid that ordinary people don't have such medical knowledge, I feel that the murderer is a doctor, so as to explain why he has such superb knife skills and understanding of medical knowledge, and the hospital also has a place to store corpses at low temperatures." ”

Li Jun put down his pen and stared at Zhang Bin, shook his head gently after about ten seconds, and said in a low voice: "No, being a criminal police officer is the most taboo preconceived, the murderer is a doctor can only be used as a direction of detection, not to put all hope on this, is it possible that a chef or butcher can't teach himself some medical knowledge?" Or the murderer was a doctor before he came to Songhai, and now he has come to Songhai City to do other industries, and the people around him don't know that he was a doctor before, so it is not impossible, Songhai City's daily floating population is very large, if you only catch the murderer is a doctor, in the end, it will delay the best opportunity to solve the case. ”

After waiting for a few more minutes, Li Jun saw that no one came up with a new point of view, so he asked the dissolution to find the identity of the victim. And asked people to notify the city's district police station to scatter all the people out, looking for the broken corpses that may have been abandoned by the murderer somewhere.

"Since many people have already seen the scene of the dumping of the body in the morning, then simply notify the matter and use the means of the media to find the information of the victim, which can also greatly speed up."

Sun Jianguo snuffed out the cigarette butt, squinted at Li Jun and said, "Do you really want to do this?" If we don't issue a notice, our time is not too tight, and if the case is notified to the society, the pressure on the city bureau is not small. ”

Li Jun smiled bitterly and said, "If you keep it like this, I'm afraid it won't be long before it becomes a headless mystery again." Not to mention the power of society, I believe that someone will soon come to the police station to identify the body, once the identity of the body is determined, the help to solve the case is not ordinary. ”

Sun Jianguo nodded and didn't speak again, agreeing with his words.

When only Li Jun, Sun Jianguo and myself were left in the department, I suddenly woke up and found that Team Li didn't seem to have assigned me a task.

Thinking of this, I was going to go out to find a job, and as soon as I got up and walked to the door, Li Jun suddenly raised his head and said: "Xiao Xu, you stay here, Xiao Wu, who went to adjust the monitoring, will come back later, you can help take a look." ”

I scratched my hair and sat back in my chair and waited, but Corey's first and second in command didn't speak, and I was even more embarrassed to speak, so I could only sit in my chair and wait anxiously for someone to come back. The cigarettes in Sun Jianguo's mouth lit one after another, the ashtrays on the table were almost filled, and the room was filled with heavy smoke, and Li Jun stared at the paper on the table, not knowing what he was thinking.

About half an hour passed, the door of the room was pushed open, I subconsciously looked up, a somewhat familiar police officer walked in, I tried to recall, this person seems to be called Wu Shuangshuang, graduated last year and was arranged to work in the bureau, in the morning and the deputy team Kan Dashan, I also heard him mention it, but the deputy team likes to call him Wu Siyou, or Wu Youyou.

When Sun Jianguo saw someone coming, he immediately extinguished the half-smoked pestle, and hurriedly urged: "Wu Si, quickly connect the surveillance video to the projector and play it to see." ”

Wu Shuangshuang quickly connected the memory to the computer and used the projector to start playing the monitoring.

The first surveillance video comes from the intersection on the north side of Songhua Street, judging from the surveillance footage, the camera's shooting range can cover the entire situation of the intersection, if the murderer enters the scene of the body from the intersection on the north side of Songhua Street, it will definitely be filmed.

The start time of the video started at 8 o'clock last night, Wu Shuangshuang explained that they asked the merchants near the garbage station that the last time the Songhua Street garbage station was cleaned up last night was at 20 o'clock, so he went to the traffic police team and directly adjusted the monitoring from 20 o'clock to 7 o'clock in the morning.

Because there were eleven hours between eight o'clock last night and seven o'clock this morning, Li Jun asked Wu Shuangshuang to set the playback speed to four times, so it was also very efficient to view.

I can't see the sliced human tissue, but I still have the ability to look at the surveillance, remembering the rhetoric on the train, I rekindled my fighting spirit, and carefully stared at the video played on the projector screen, hoping to find clues to the murderer, and to get back the face I lost at the scene of the crime.

The screen switches quickly, but it's just enough to be seen. In '02, cars were not yet commonplace, so there weren't many cars driving into Songhua Street, and occasionally a few bicycles passed by.
