Chapter 1043 Professional
After Huang Qiangmin came back from the meeting, he went to Building 9 first.
After greeting Liu Jinghui, Huang Qiangmin asked, "Is there really someone provoking the police? Are you so desperate?"
"It's nothing new. Several major cases in our country were all provocations to the police. Just like that case, it turned into a murder of a police officer..." Liu Jinghui stopped talking briefly and continued, "The psychological problem of the murderer is indeed worth discussing. For many serial killers, it may be necessary to deduce clues from a psychological perspective."
"Isn't it based on reasoning?" Huang Qiangmin said half-jokingly.
Liu Jinghui had a blank expression on his face: "I am now reasoning, and I have deduced the need for clues."
"Criminal psychology? No one uses this stuff anymore." As a former front-line police officer, Huang Qiangmin can only say that he "takes a look" at things like criminal psychology, criminal profiling, and polygraph testing, and he has no confidence in them.
Liu Jinghui smiled and uttered a name: "Li Haochen."
"He's with the ministry." Huang Qiangmin had thought about managing upwards, but he had never thought about managing so much upwards.
"Criminal profiling. He won't encounter this kind of thing even if he stays in the Criminal Investigation Bureau. How rare it is."
"Then let's look for it?" Huang Qiangmin looked at Jiang Yuan.
Jiang Yuan spread his hands: "I can do anything."
We have to ask for help from outside 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 sure whether it was useful or not.
As the saying goes, ten profiles, eighty angles, in the end, the same thing happens when you look at a mountain from the front and a peak from the side. If you want to try your best to save a dying horse, it is not impossible.
Huang Qiangmin did not make the call immediately, and asked Liu Jinghui again: "So now, what are your ideas and directions?"
Liu Jinghui hesitated for a moment and said, "To be honest, I don't have a direction yet. 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 different from those of ordinary murderers."
"It's also more difficult to investigate." Huang Qiangmin breathed a sigh of relief, and understood very well what Liu Jinghui meant.
This actually involves something deeper. For example, the investigation of murder cases has been carried out based on interests and interpersonal relationships for a long time.
This is easy to find out from the early British detective novels. The so-called detective reasoning is based on the interests and interpersonal relationships of normal people. If you assume that a person has nothing to do with you, you will not kill him.
Killing without reason is difficult to accept in detective novels or in mystery itself.
Normally, this is true. The risk of killing is so great and the punishment is so severe, who would kill for no reason?
Neuropathy!
When a psychopath kills someone, it is very difficult to reason and judge because he does not follow common sense. Of course, the technical means of modern society are very advanced, such as fingerprints, DNA, surveillance videos and mobile phones, which have surpassed these reasoning methods, but if you are facing a well-prepared psychopath, the difficulty of solving the case becomes very high.
"We need to communicate with the provincial department and the ministry about this case." Liu Jinghui raised his eyebrows and said, "No matter whether we can solve the case in the end, it is unacceptable for a murderer to provoke the police with such brutal means."
Huang Qiangmin understood as soon as he heard it. Indeed, the case was so complicated that there was no need for him to hold on to it. Fundamentally speaking, this case was not a case of Ningtai County, nor a case of the Taihe Working Group. It was a byproduct of the reputation that Jiang Yuan had accumulated over the years.
To be more specific, the cost of this case cannot be borne entirely by Ningtai County, otherwise it would be too unreasonable. We cannot let the heroes shed both blood and tears.
As to whether the case is as Liu Jinghui said, we will know after the provincial departments and ministries send personnel to take a look.
In theory, Liu Jinghui is from the provincial department and Li Haochen is from the ministry, but that is not enough.
Huang Qiangmin was very familiar with this aspect. After talking to Jiang Yuan for a few words, he made the phone call.
Liu Jinghui turned around, looked at Jiang Yuan, and said, "It seems that the murderer is indeed a bit professional?"
"Hmm..." Jiang Yuan had actually been thinking about this question in recent days. With Liu Jinghui discussing it with him, he said, "We can't be sure of his modus operandi yet, but I think he must have carefully selected his victims, or at least studied them thoroughly."
In the case of a serial killer, if the modus operandi can be analyzed, the probability of solving the case is very high, and a lot of information is needed here.
Furthermore, when encountering a case of a serial killer, the first thing we should try to do is to analyze the modus operandi.
However, what Jiang Yuan said about selecting victims is actually a relatively obscure aspect.
Liu Jinghui was curious: "Why do you say that? How does he choose his victims?"
Jiang Yuan organized his words and said, "Because among the three bodies, the information revealed by Body No. 1 and Body No. 2... How should I put it? We have discussed Body No. 2. It only has five fingers, so there is no need to throw it out. Although the hands of Body No. 1 were severely rotten, after obtaining fingerprints, there was no match. This is very special, because the body drifted in the water for an uncertain time, and the murderer was not sure whether we could obtain fingerprints. Why didn't he cut off the fingers of Body No. 1?"
"Maybe it's the first body and he hasn't noticed it yet?"
"But the time difference between the deaths of No. 3 and No. was only three days. The murderer must have thought it through before he started killing people."
"You're right. His treatment of the first body shouldn't have been too different in nature. So, you think the murderer was sure that the fingerprints of body No. 1 couldn't be matched, so he deliberately kept the fingerprints of body No. 1?"
Jiang Yuan thought for a moment and said, "He may have his own ideas for leaving his finger behind, but I think he left the finger of corpse No. 1 to make sure that the fingerprint of corpse No. 1 would not reveal any information."
Liu Jinghui's expression became serious: "What you said is interesting... If this is a ritual, then the murderer is likely to first make sure to leave behind the finger of corpse No. 1, and then make sure that the fingerprint of corpse No. 1 will not leak any information..."
"But body No. 2 only had fingers, and yet we were able to match the fingerprints..." Tang Jia was very interested in this case, and he was thinking while taking notes.
Liu Jinghui nodded: "The only information about the second body is the fingerprints. From the perspective of a serial killer, doesn't it seem more... intentional?"
Tang Jia couldn't help but frown: "If the murderer is sure that corpse No. 1 will not reveal fingerprints, then the fingerprints of corpse No. 2 will definitely be matched... What kind of conditions does he need? Could it be... a colleague?"
Liu Jinghui was silent for a few seconds, then looked at Jiang Yuan and whispered, "It's not ruled out. But this idea is just an idea for now. Before there is solid evidence, I suggest not discussing this topic."
"The identity of the murderer will directly determine the route of investigation." Tang Jia is naturally knowledgeable.
"We can just investigate it ourselves. Don't make it public. It's best to notify a small group of people. Besides, anyone who has access to the intranet may be able to find relevant information." Liu Jinghui paused and continued, "Also, we have to 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 them. After selecting the candidate, just investigate secretly. It's not too difficult to buy information on the dark web."
Tang Jia was not discouraged and pressed on: "But since the murderer was able to contact the victim offline, wouldn't it be easier to get to know the victim and then secretly verify the facts? It's less intensive than a secret investigation, so this should be an advantage."
"Your point of view does make sense." Liu Jinghui did not deny it again, and said: "But if we want to investigate through the victim, we must first know who the victim is."
They both looked at Jiang Yuan.
