"Xiao Xu, how is your situation over there?"

I opened the account book and reported truthfully: "There are two shops selling sodium hydroxide in the city, and now the investigation has been completed, and a total of three people have bought sodium hydroxide in the past three months, one is Guo Chao from the city hospital, the other is Professor Jin Weijia of Songhai University, and the last one is Zhou's Paper." ”

The other end of the phone paused for a few seconds, and finally said: "You are a newcomer, you are not familiar with this aspect of the process, come back for a meeting first, and I will let Xiao Liu take you there when it is over." Now the team is going to hold a special case group meeting, and the identity of the victim has been determined. ”

When I returned to Corey's conference room, the people outside were basically all there, I looked at Li Jun, and when I saw that he motioned for me to sit down, I found a place to sit down on the outermost periphery.

Coughing lightly, Li Jun said with a cold face: "In order to determine the identity of the victim as soon as possible, I asked people to send out the revelation of the corpse search, although the identity of the victim has been determined, but now the impact is also very bad, all kinds of rumors are flying in the city, what crazy murderers, dozens of people have been killed, and there are ogres and the like, slicing people and cooking them, and various versions have noses and eyes." The bureau has notified the media to do their best to refute the rumors, but if the case cannot be solved as soon as possible, it will be useless to refute the rumors. ”

"Let me tell you about the latest development of the case, after the body search revelation was issued, a student from Songhai University came to us and said that her roommate Liu Shuqian did not come back after going out on the evening of July 3, and the photos on the body search notice were very similar to her. Later, we extracted the hair left behind by Liu Shuqian in her dormitory, and through DNA testing and identification of the cells in the hair follicles, we finally determined that the two broken bodies found at Songhua Street and Huangpu Street this morning were Liu Shuqian, a first-year student at Songhai University. ”

Liu Shuqian, 20 years old, from Jingzhou, Hubei, was admitted to Songhai University in September 2001, and stayed on campus for part-time work this summer. According to the inquiry of Su Qi, Liu Shuqian returned to the dormitory after working part-time on July 3, changed her clothes and said that she was going to the bookstore, and no one came back since. I thought she was going home, so I didn't care, and I didn't rush to the police until I saw the revelation of the body at the school gate today. ”

"According to the telephone interview with Liu Shuqian's counselor and classmates, it was found that Liu Shuqian herself is more introverted and not good at communication, because her family is poor, and even has some low self-esteem, so her social circle at school is very small, except for the five roommates in the dormitory, and the people in the class have never said a few words, and she has never seen her have friends of the opposite sex, so it is currently preliminarily judged that a stranger committed the crime, and someone has been sent to conduct a detailed investigation of Liu Shuqian's whereabouts that day."

"This is the victim's autopsy report, you can pass it on to each other, and say what you think."

Liu Yefang raised her hand and signaled, and Li Jun stopped and looked at her: "Xiao Liu, what questions do you have?" ”

"What clothes did the victim Liu Shuqian wear on the night of July 3 to go out to which bookstore? What time do you leave the dormitory? Did you do anything unusual before leaving? ”

Li Jun flipped through the information in his hand and said: "Liu Shuqian was wearing a white and green plaid shirt on the upper body that day, and the lower body was a pair of black trousers. As for the time of going out, her roommate recalled that it was around 6:30 p.m. on the 3rd, and at the same time, she did not make any special moves before going out, and made the bed as usual. ”

"As for which bookstore she went to, she was still investigating, and when she left, she didn't tell her roommate that there are many bookstores around Songhai University, and it will take some time to investigate."

Liu Yefang nodded after hearing and didn't ask any more questions, and after a while, Li Jun looked at her and said, "Xiao Liu, you are studying psychology, can you analyze this case from the perspective of criminal psychology?" ”

Seeing many people looking at him, Liu Yefang thought for a few seconds and picked up the autopsy report and read it carefully, and finally said cautiously: "From the current situation, I have some opinions of my own, but they are all just speculations, after all, there is still too little evidence now." ”

"First of all, I said that the relationship between the murderer and Liu Shuqian is nothing more than an acquaintance committing a crime, a stranger committing a crime, or a person with a simple side or several sides of the friendship to commit the crime, I personally prefer the third type, because Liu Shuqian had just arrived in Nanjing to study for a year, plus introverted, there will be no acquaintances, and the police will definitely investigate first after the acquaintance commits the crime, and more importantly, the reason why the murderer dares to keep the body at home for a long time and calmly break the corpse is that his psychological self-confidence stems from his unfamiliarity with the victim. No one knew or could have imagined that the victim had come to their home. ”

"The victim Liu Shuqian went out at half past six in the evening and laid out the quilt before leaving, which indicates that she is going back to sleep at night, and the potential information indicates that she has no intention of staying overnight. Now this season, when the sun is still there at half past six and the sky is bright, Liu Shuqian cannot be killed on the road, but after entering the murderer's home. In other words, the place of the murder and the place of dismemberment were in the same place. ”

"As for complete strangers committing crimes, I can only say that they are basically ruled out, if Liu Shuqian entered the murderer's house in a peaceful way, then she should have a little basic trust and good impression of the murderer, and it seems difficult to temporarily generate this trust at night with a completely unknown person on the street, but after all, accidental things still exist in reality, although Liu Shuqian is introverted and not good at socializing, but introverts are sometimes bolder and less vigilant."

Liu Yefang looked around, saw that no one spoke, and then said: "Secondly, the possibility of renting a house can be basically ruled out, the body is cut into thin slices, and the murderer can break the body so slowly and methodically, he must have an absolute grasp of the safety of the place, not under normal circumstances, nor basic safety, but absolute safety." For a rented house, at least the landlord also has the key, at least he can't fully control the room, if it's a rented house, the murderer will definitely break the body as soon as possible, throw the body as soon as possible, and reduce the risk, so I think the murderer must be the owner of this residence. ”

Li Jun knocked down the pen and agreed: "That's right, Lao Sun and I also think the same, and at the same time, based on this, we speculate that the murderer is a native of Songhai, which excludes the possibility of outsiders running around to commit crimes." Moreover, the scope of the residence is in the eastern part of the city, because the location of the body is very concentrated, and the murderer has no convenient means of transportation, so he can only throw the body on foot or by bicycle. ”

Liu Yefang took over the conversation and continued: "When I returned to the bureau this afternoon, I heard the comrades who had a meeting in the morning say that Deputy Sun deduced that the murderer might be a butcher or a cook, but I found that this possibility is very small from Liu Shuqian's social behavior characteristics and personality tree diagram. Songhai University is a well-known university in the country, and Liu Shuqian is a college student, how can she be interested in or have a good impression of a butcher? If these basic elements are not present, there will be no trust and no access to the murderer's home. ”

"I deduce that the murderer is likely to be a highly educated intellectual, or has some kind of skill that interests Liu Shuqian, and in this regard, I think the team can start to investigate from Liu Shuqian's usual hobbies and daily use notebooks, and maybe they can find clues."

"The general situation on the night of July 3 should be like this, Liu Shuqian left the school gate and was about to go to the bookstore, and on the way, she happened to meet the murderer who had met several times, and it is also possible that the murderer has been squatting. After that, the murderer invited Liu Shuqian to his home as a guest, or said that there was something in the house that could attract her, so as to let Liu Shuqian go to his house in a relatively peaceful way. ”

When Sun Jianguo heard this, he took out his cigarette case and wanted to smoke, but found that the occasion was a little unsuitable and put it in his trouser pocket, and then said in a hoarse voice: "Indeed, what you said is very reasonable, I didn't think it through this morning, but what puzzles me the most is why did the murderer decompose the corpse into more than two thousand pieces of minced meat?" Where is the rest of the minced meat now? In the afternoon, Wu Si went to the traffic police station to check the vehicles that passed through Songhua Street last night, according to the filing information, we contacted the owner of the car and found that there was no possibility of committing a crime, and how the murderer threw the body is also a headache. ”

Liu Yefang thought for a moment and said uncertainly: "I can't think of the murderer's method of throwing the corpse now, but I can roughly guess the reason for breaking the corpse into more than two thousand pieces." ”

"The decomposition of the corpse into more than two thousand pieces, such a case has never been seen since the founding of the People's Republic of China, and I guess it is related to the motive of the crime, from the perspective of criminal psychology, the motive of the crime is nothing more than vendetta, love killing, seeking money, missing hands, and sexual assault. First of all, vendetta, love killing, seeking money and missing hands can be ruled out, Liu Shuqian is introverted, usually does not make enemies with people, even if there is a little grudge, it can't rise to the point of vendetta, as for love killing, Liu Shuqian In addition to being in Nanjing for a short time, if she has emotional entanglements with her boyfriend, it is difficult to be airtight, and her roommates who get along day and night will definitely find clues, but the result of the investigation is that Liu Shuqian does not seem to have friends of the opposite sex. ”

"It is impossible to make money and miss the two kinds, Liu Shuqian's family is poor, and there are only two sets of clothes in the dormitory, so making money can be ruled out, and the second kind of mistaken murder, even if it is this case, there is no need to decompose the body into more than two thousand pieces."

"The only thing left is sexual assault, the murderer cut the body into more than 2,000 pieces, careful and meticulous, on the surface it seems to show the murderer's cruelty and perversion, but what is really exposed is the murderer's great panic, in order to escape the legal punishment and have to do nothing. And the more blocks the body is divided, the less evidence is left, the more convenient it is to throw the body separately, the less noticeable, and if the number of blocks is infinite, the evidence is close to zero. This basically excludes the possibility that the murderer of the 7.14 corpse mutilation case provoked society and killed people in a perverted manner. ”
