Chapter 1043 Professional

Huang Qiangmin came back from the meeting and came to Building 9 immediately.

After saying hello to Liu Jinghui, Huang Qiangmin asked: "Is there really someone provoking the police? Is this so unthinkable?"

"It's nothing new. Several major cases in our country were provoked by the police. It's like those cases turned into murders of police officers..." Liu Jinghui stopped briefly, then continued: "The murderer's psychological problem, It can indeed be discussed carefully. Many serial killers may really have to deduce clues from the psychological level. "

"Isn't it based on reasoning?" Huang Qiangmin half-joked.

Liu Jinghui said expressionlessly: "I'm just reasoning now, and I've reasoned out the need for clues."

"Criminal psychology? No one uses this stuff anymore." As a former front-line police officer, Huang Qiangmin can only say "see" about criminal psychology, criminal profiling, lie detection and the like. Look”, trust is out of the question.

Liu Jinghui smiled and spit out a name: "Li Haochen."

"He is from the ministry." Huang Qiangmin thought about upward management, but never thought about upward management.

"Criminal profiling, he can't find it even if he stays in the Criminal Investigation Bureau. How rare it is."

"Let's look for it?" Huang Qiangmin looked at Jiang Yuan.

Jiang Yuan spread his hands: "I can do it."

Instead, we need to hire foreign aid for our own case. I can only say that a sense of responsibility is a good thing.

As for Li Haochen's criminal profile, Jiang Yuan was not very sure whether it was useful or not.

As the saying goes, ten profiles, eighty angles, until the end of the profile, it looks like a ridge on the side and a peak on the side. If a dead horse is used as a living horse doctor, it is not impossible.

Huang Qiangmin did not call immediately and asked Liu Jinghui: "Now, what are your thoughts and directions?"

Liu Jinghui hesitated for a moment and said: "To be honest, I have no direction at the moment. If my inference is correct and the murderer's purpose of killing is indeed to provoke the police, then his behavior pattern and method of doing things are the same as those of ordinary people." The murderer is different."

"It's also harder to investigate." Huang Qiangmin breathed a sigh of relief, fully understanding what Liu Jinghui meant.

This actually involves something deeper. For example, the investigation of murder cases has relied on interests and interpersonal relationships for a long time.

Looking at early British mystery novels, it will be easy to find that the so-called detective's reasoning is based on the interests and interpersonal relationships of normal people. Assuming that a person has nothing to do with you, you will not kill him.

Killing without reason is difficult to accept in mystery novels or reasoning itself.

Normally, this is true. The risk of killing is so high and the punishment is so high. Who would kill someone if nothing happens?

Neuropathy!

When a psycho kills someone, he doesn't follow common sense and it's difficult for him to reason and make judgments. Of course, the technological means in modern society are very advanced. Fingerprints, DNA, surveillance videos, mobile phones, etc. have surpassed these reasoning methods. However, if you face a well-prepared psychopath, it will be very difficult to solve the case. High.

"This case needs to be communicated with the provincial departments and ministries." Liu Jinghui raised his eyebrows and said, "No matter whether we can finally solve it or not, it is unacceptable for a murderer to provoke the police with such cruel methods."

Huang Qiangmin understood immediately when he heard it. Indeed, if the case is so complicated, there is no need to hold on to it. Fundamentally speaking, this case is not a case of Ningtai County, nor a case of the Taihe Working Group, but Jiang Yuan A secondary creature of the reputation accumulated over many days.

To be more specific, Ningtai County cannot bear all the funds for this case, otherwise, it would be too unreasonable. The hero cannot be made to bleed and cry at the same time.

As for whether the case is as Liu Jinghui said, the provincial department and ministries will send people down to take a look.

To sum up, Liu Jinghui is from the provincial department and Li Haochen is from the ministry, but it is not enough.

Huang Qiangmin was very familiar with this aspect. After communicating with Jiang Yuan for a few words, he went to make a call.

Liu Jinghui turned around, looked at Jiang Yuan, and said, "It seems like the murderer is indeed a bit professional?"

"Well..." Jiang Yuan was actually thinking about this issue in the past few days. With Liu Jinghui beside him to discuss it, he said: "His method of committing crimes is not yet certain, but I think he must have carefully selected his victims. ”, at least it’s been studied in depth.”

In the case of a serial killer, if the modus operandi can be analyzed, the probability of detection is very high, and a lot of information is needed.

Furthermore, when encountering the case of a serial killer, the first thing to try is to analyze the modus operandi.

What Jiang Yuan said about choosing victims is actually a relatively unfamiliar aspect.

Instead, Liu Jinghui got serious: "Why do you say that? How does he choose his victims?"

Jiang Yuan organized his words and said: "Because among the three corpses, the information exposed by corpse No. 1 and corpse No. 2... How to put it, we have discussed that corpse No. 2 only has five fingers, so there is no need to throw them out. One Although the hands of corpse No. 1 were badly decomposed, after obtaining fingerprints, there was no match. This is very special, because the time the corpse was floating in the water was uncertain, and the murderer was not sure whether we could obtain fingerprints. Why not cut off the fingers of Corpse No. 1?”

"Maybe it was the first body and he hadn't noticed it yet?"

"But the time difference between the death of No. 1 and No. 2 was only 3 days. The murderer must have thought carefully before he started killing."

"You're right. His handling of the first corpse shouldn't be too deviant in nature. So, you think the murderer was sure that the fingerprints of corpse No. 1 were incomparable, so he deliberately kept corpse No. 1 fingers?"

Jiang Yuan thought for a while and said, "He may have some idea of ​​leaving his fingers, but I think that he left the fingers of Corpse No. 1 to confirm that the fingerprints of Corpse No. 1 would not leak information."

Liu Jinghui's expression became serious: "What you said is a bit interesting... If this is a ritual, then the murderer probably made sure to leave the fingers of Corpse No. 1 first, and then made sure that the fingerprints of Corpse No. 1 would not be leaked. Come out with information..."

"But corpse No. 2 only had fingers, and it turned out that the fingerprints could be compared..." Tang Jia was very interested in this case, and while taking notes, he was also thinking about it.

Liu Jinghui nodded: "The only information on corpse No. 2 is fingerprints. From the mentality of a serial killer, does it seem more... intentional?"

Tang Jia couldn't help but frown: "If the murderer is sure that corpse No. 1 will not leak fingerprints, and the fingerprints of corpse No. 2 will definitely be compared... what conditions does he need? Could it be... a fellow traveler?"

Liu Jinghui was silent for a few seconds, then looked at Jiang Yuan, and whispered: "I can't rule it out. But this idea is just an idea for the time being. Before there is conclusive evidence, I suggest not to talk about this topic."

"The identity of the murderer will directly determine the investigation route." Tang Jia naturally knows his stuff.

"We just need to check it ourselves. Don't say it in a big way. It's best to notify a small area. Furthermore, anyone who has access to the intranet may be able to find relevant information." Liu Jinghui paused and then Said: "Moreover, we must consider it from the perspective of the victim. If the victim himself has not been dealt with administratively or criminally, and has not left any traces in the police system..."

"Then the murderer must know the victim?" Tang Jia's eyes lit up.

Liu Jinghui coughed twice and said: "It's not necessary to know each other. After selecting the candidate, just conduct a secret investigation. It's not too difficult to purchase information on the dark web."

Tang Jia was not discouraged and asked: "But since the murderer can contact the victim offline, wouldn't it be easier to know it and then verify it secretly? It is less intensive than a secret investigation, so this should also be beneficial."

"Your point of view makes some sense." Liu Jinghui did not deny it anymore, but instead said: "But if you want to investigate through the victim, you must first know who the victim is."

Both of them looked at Jiang Yuan.
