Profiler 2: Criminal Investigation Brigade

"It must be allowed!" Manager Li said with a wry smile, "Now online shopping is so common, covering food, clothing, housing and transportation. The property does not allow express delivery, so the owner has to make trouble for you? But the express delivery here usually delivers directly The things that arrive are stored in the express cabinets on both sides of the first floor. There are several express cabinets in the community. They rarely deliver goods in the building. Such a tall building is so troublesome. Unless it is SF Express, ask to come to the door. "

Jiao Yang said: "However, even if there are couriers coming in, the general owners will not be surprised, will they?"

Manager Li nodded and said, "That's right."

Jiao Yang thought for a while and said, "In our community, are there many criminal investigation houses under renovation?"

Manager Li said: "Yes. This community was only put into use in July, and the residents who moved in have indeed been undergoing renovations one after another."

Jiao Yang said: "We still have work to do, please cooperate. We need all the contact information of the decoration company used by the owner who is currently renovating, as well as the contractors below. Please contact these owners and explain the purpose. Be sure to Ask them to be vigilant and pay attention."

After arranging everything, Jiao Yang felt a little tired, turned to Lu Yuanli and said, "What do you think?"

Lu Yuanli murmured, "Looking at it now, there is no doubt about the series of cases. Let me do the profiling."

Another sleepless night with all staff working overtime.Early the next morning, the autopsy report and on-site inspection report from the technical investigation department were delivered.

Jiao Yang read the report with a more serious expression.The autopsy report confirmed that the deceased was strangled and then hung from a chandelier.However, the hair, fingernail fragments and other objects found at the scene were confirmed to belong to the deceased and the deceased's cleaner Tan Xiaoai and her husband Wei Peng respectively.In other words, the murderer committed the crime cleanly, except for the two footprints, there were not many traces left at the scene.

Jiao Yang turned to Shen Rui and said, "How's the situation of the decoration company?"

Shen Rui reported: "In the three cases, in the first two communities, there were three owners who were renovating at the same time, and they belonged to six different decoration companies. The community where the third case occurred, because it was a new community, had 200 owners who were renovating. , belonging to [-] companies. The list of preliminary statistics now has more than [-] workers. We are still verifying and investigating one by one. During the construction site, who has been out for a long time. "

Jiao Yang nodded and said, "What do you think now? Can Xia Ke and Meng Zhaowei be ruled out?"

Yu Xiaoguang said: "There is a difference of more than ten days before and after each case. Could it be a case of imitation?"

Jiao Yang said: "Probably not. On the one hand, our country's media is relatively reliable. I asked Mo Ke and Zhou Ying to search the Internet, and the relevant case reports, time, and location are all blurred. No details."

Hou Xiyong gasped and said, "That's not really a wife-killing alliance committing crimes, is it? That's too scary!"

Zhang Xianning said: "It's not that mysterious. I think it can basically be determined that it is a series of cases."

Jiao Yang turned to Lu Yuanli and said, "Professor Lu, you've finished the profiling, right? You can start now."

Lu Yuanli said: "Through the summarization of the three cases, although the murder methods are different, I tend to believe that the same person did it. Then, let me summarize the characteristics of the murderer.

First, the murderer should be a young male, a manual laborer, with a relatively strong physique.In these three cases, judging from the cause of death and injuries of the female victims, most of them were killed at the same place, and there were not many struggling and resisting injuries on their bodies.This shows that the murderer's physique should not be bad, and he can easily subdue the female dead and kill them immediately.

Second, the murderer has a certain anti-reconnaissance ability, but his education level is not high. This ability seems to come from talking on paper, such as detective novel lovers.

In these three cases, except for the contents of the stomach in the first case and the three footprints, the murderer did not leave other body fluids, bloodstains and fingerprints, etc. Certain anti-reconnaissance awareness.

Moreover, I feel that the murderer is deliberately guiding the police, pointing the direction of suspicion to the husbands of the three dead women.For example, in the first case, the lettering of "not obeying women's morals" was written, and in the second case, the wedding photo of the deceased woman and her husband was deliberately smashed.

However, in the second case, the murderer went to the balcony to step on it, leaving footprints.This shows that the murderer did not know that the police can distinguish different behaviors such as stampede and climbing, and the traces of the footprints caused are also different.In my opinion, this should be a matter of common sense.So I feel that the murderer's education level may not be high.

Moreover, in these three murders, the murderer seems to have deliberately adopted completely different methods of killing.For the first time, the female victim was stabbed with a knife.The second time, the victim was hit on the head and face with a hammer.The third time, strangle the victim.

However, it is precisely because of these little tricks that I caught the third characteristic of the murderer.That is, there are some obvious problems with the psychological state of the murderer.The three murder scenes all have a distinctive feature, that is, "excessive crime".

For example, in the first case, the deceased woman had already been stabbed to death.Why did the murderer have to disembowel and engrave letters, and also turned over the internal organs of the dead woman.Apart from wasting time, these actions are meaningless in the eyes of ordinary people.

The second time is the same, a manual laborer, of course, knows that a hammer of that weight, aimed at the back of the head, can kill the opponent with just one or two blows.

Even a few blows aimed at the face can cause death.However, the murderer did not choose the easier back of the head as the murder site, but repeatedly beat it hard until the head and face of the dead woman were bloody and bloody, and it was basically unrecognizable.

The third time was almost ridiculous.After the murderer killed the messenger with his bare hands, he could have escaped immediately.He had to use the hemp rope he brought to hang the dead woman on the chandelier.

This place, on the one hand, attracted the attention of the residents downstairs, causing the case to break out earlier, and on the other hand, it once again showed that the murderer's education level was not high.I think ordinary people should also know that a chandelier is not a beam and cannot bear the weight of a person, especially the dead.And afterwards, the murderer also destroyed the cloakroom of the dead woman.

What do these procrastinating, inexplicable methods in the eyes of ordinary people mean?It represents subconsciously, the murderer's resentment and hatred towards women.In the first case, the chest was engraved with the words "not obeying women's morals" around the female features. This kind of slander and attack text itself has a humiliating meaning.

The No.2 female deceased was beautiful.So the murderer repeatedly beat the victim's head and face, subconsciously, to destroy the appearance of the deceased woman.At the same time, smashing the wedding photos of the deceased woman and her husband also contained resentment.This place may explain the fourth characteristic of the murderer, I will talk about it later.

These few places show that the murderer hates women and is psychopathic.And the three female victims he chose were all women with relatively strong personalities.This shows that he may have been under the oppression of several strong women for a long time.

And then I'll go back to the fourth feature that was just paused.Smashing wedding photos may also have a hint of jealousy in the subconscious.It shows that the murderer is a heterosexual, probably because he is relatively poor, has an average appearance and personality, and has been single for a long time and cannot find a partner, so he hates married women even more.

Last but not least, the murderer destroyed the cloakroom of the No. 3 female deceased, which shows that he has a certain hatred of the rich.Or born in an area with a relatively backward concept, they are very disgusted with women who love to dress up and own a lot of personal items.

On the whole, the murderer is a young man from an average family background, poorer, less educated, physically fit, with certain anti-reconnaissance capabilities, who knows some plausible theories and regards them as a standard, but often thinks he is smart because of this.

Also, I agree with Team Jiao.The murderer is likely to be among the workers hired by these decoration companies.The suspected rain boots and waterproof clothing worn by the murderer can all prove this point.If the murderer is a decoration worker, then his body is prone to dust, and he will often change and wash.In this way, the part of his clothes that is wet will not attract other people's attention. "

"Grass!"

Hou Xiyong couldn't help scolding: "At first, I thought that serial killers were products of bourgeois culture in Western society. I didn't expect that there are so many neuropathy in a socialist country with such roots as ours. kill!"

"Don't talk in layman's terms. In the former Soviet Union, it has been confirmed that this sentence is a false proposition."

Jiao Yang said: "The same rice feeds a variety of people, how to control so many people? No matter how good the soil is, there will always be a few bad seedlings growing crookedly."

After everyone took notes, the meeting was adjourned.

Jiao Yang stopped Zhang Xianning and said, "Go to the detention center and let me know, let Xia Ke go."

It was already early morning when the two returned home.Jiao Yang lit a cigarette, slowly exhaled the smoke ring and said, "Do you think I'm incompetent? Just because I didn't dare to recognize it as a series of cases, Xia Ke spent so much time in the detention center for nothing. God. And in a way, it's misdirected the investigation."

Lu Yuanli patted him on the shoulder and said, "Just like what Hou Xiyong said, in fact, you just don't want to admit that in a society like ours, there are perverted killers for no reason. One more thing, there is a third person at the scene of the murder , and Xia Ke's suspicion of murder cannot be ruled out, it is right to be more rigorous."

Jiao Yang hugged him lightly and said, "Then do you think I'm a dog man? I'm so busy with work, I don't have any special time to accompany you. Chatting is nothing more than discussing business matters. You can solve the case if you have something to do, and bully you if you have nothing to do! "

Lu Yuanli couldn't help laughing, "I have a deep understanding of myself. It's just not enough to reflect on myself. I must actively admit my mistakes and work hard to correct them!"

"How to change it?" Jiao Yang kissed him on the cheek and said, "When this case is solved, can I make shrimp dumplings for you myself? You don't need my old lady to do it for you. I will give you whatever you want in the future." You do it, okay?"

"This is all your business!"

Lu Yuanli lowered his head and rubbed the tip of his nose, "You are the one who dumped it on the old lady, it's none of my business!"

Now that the case has progressed to this point, there are many difficulties in further investigation. First, there is a lack of direct evidence. Second, the scope of the investigation is large. Third, according to the profile written by Lu Yuanli, there is no logical relationship between the perverted serial killer and the murderer and the victim. , no reasoning chain can be formed.

The next day, the police re-investigated the scene of the first homicide.Jiao Yang, who was wearing casual clothes, suddenly spotted a man in the surrounding crowd.This man was of medium build, young, dressed like a construction worker, his eyes flickered, and he was holding a copy of "Procuratorial Daily".
