After the training was revealed, Guan Hongji handed over another file.

“？”

"Aren't you curious about the case you came across back then?"

Could it be?

Min Xue took it and looked carefully, it was really the murder and corpse mutilation case that imitated "Chasing the Murderer in the White Night" when he was a film policeman, that is, the "9.29" case.

At that time, due to the limitations of his position, he could only be on duty on the periphery, and he knew little about the inside situation.

Min Xue is not uncurious about this case, but there are some things, for various reasons, it is really difficult to inquire, and I don't know why Guan Hongji suddenly remembered to show him.

Abandoning the cranky thoughts in his mind, Min Xue looked through the archives in his memories.

The first case was the dumping of a body in the park.

In the second case, a body was dumped on the lawn in front of the bar.

The third case, a murder in a bar...

Wait, the third case? Min Xue remembers that the third case was investigated by three teams, right? Bao Zimo was still there, how did it merge together?

The first two cases are naturally related, the three people were killed and thrown twice, and Min Xue was also asked to "assist in the investigation" because he was the author of the original work.

It's just that in this third case, isn't the bar lead singer Wang Ming killed? This case is also related to the first two?

Seeing that Guan Hongji didn't mean to let him take the file, Min learned clearly, and the two secretly reached a tacit understanding, and no one was in a hurry.

With questions, Min Xue continued to read.

The file has hundreds of pages, the identity background and social relations of the deceased are listed one by one, and there are also a lot of evidence materials, and Min Xue even found some ideas for Guan Hongji to solve the case.

Time passed slowly, and two hours later, Min Xue finished browsing at a normal speed and closed the last page.

From the archives, it can be seen that every clue found in these three cases has undergone a lot of analysis, research, investigation and tracking.

But without exception, all the clues are drawn with a big cross at the end.

And the suspect, not to mention the fingerprints and hair, did not even leave a single obvious trace, and his anti-reconnaissance ability was extremely strong, just like a "ghost".

Guan Hongji put down the document in his hand, "How is it, what do you think?"

"Serial killer?" Min Xue guessed uncertainly.

The serial killer of Min Doctrine is a serial killer in the real sense, and its biggest feature is that it is "fixed", and the motive for killing, the mode of killing, and the object of killing will not be easily changed.

This is because the serial killer kills in order to satisfy a fixed ideal goal.

The average person thinks that a serial killer must look like a madman or a madman, and that he is of inferior moral character, but this is not necessarily the case.

Most of the serial killers are no different from ordinary people, some are even charming, and have noble sentiments or strict moral sense, and there is even no shortage of highly educated people.

After they are discovered, they often make the people around them feel extremely shocked, and there is a feeling of "how can such a person kill someone".

"Oh, why?" asked Guan Hongji with interest.

At that time, when he proposed to combine the three cases for trial, he encountered great resistance, but he did not expect that Min Xue's opinions coincided with his.

Min Xue didn't rush to answer, but quickly flipped through the three cases again.

Only then did he say slowly, "From the gender, experience and other aspects of the victim, there is no commonality for the time being, and from this point of view, it actually does not meet the characteristics of a serial killer." ”

"Of course, we can't make a conclusion because maybe they have something in common, but we didn't find it. ”

"The reason why I think it's a serial killer is because when I was looking at the file just now, I accidentally noticed that the autopsy report mentioned that the corpse's skin had different degrees of defects. ”

"In the first two cases, because it was murder and corpse mutilation, it was relatively normal for skin defects to occur in the process of corpse fragmentation, but in the third case..."

"The corpse is relatively intact, and it was poisoned, so the flesh and blood on the arm of the deceased Wang Ming that seem to resist the injury are blurred, which is not normal. ”

"While it may be a bit arbitrary to say this, and there's no complete theory of reasoning to back it up, is it possible that it was done by a serial killer who has a hobby of collecting skins?"

Whether Min Xue's assumption is right or wrong, no one can make a conclusion, and perhaps only after the case is solved.

Although Min Xue's thinking is a bit fanciful, the evidence is insufficient, and even many of its characteristics are inconsistent with serial killers, it is also a direction to detect.

Criminal cases are like this, in the absence of clues, there is only bold assumptions and careful verification.

The seemingly unreliable inference was instead affirmed by Guan Hongji's nod.

In fact, it was the slightest flaw in the third case, coupled with some other factors, that made Guan Hongji decide to bring the case over and deal with it together.

One dumped his body outside the bar, the other was killed in the bar, the same bar, two murders in a short period of time, is it really such a coincidence?

Guan Hongji always felt that the third case was the breakthrough point of the entire serial incident.

"Haven't there been any similar cases recently?" Min Xue couldn't help but ask.

The reason for this is because after a serial killer kills, there is generally a cooling-off period. The cooling-off period is the period between two murders.

Usually, after a serial killer commits a crime, his or her excitement will reach a peak, and it will take a while to calm down, reminisce and summarize this exuberant experience, and improve the method of committing the crime.

This period of time can vary in length from a few hours to months or years.

The interval between the last two murder cases was so short, there is no reason why there has been no action after half a year?

However, Guan Hongji gave a negative answer.

"In the past six months, there have been no similar cases within the scope of the Demon Capital," Guan Hongji said here, also a little helpless, which made it even more difficult for their speculation to be established.

"What about the whole country?" Min Xue couldn't help but ask.

"It is difficult to investigate, and it can be seen from the third case that the murderer is very cunning, random in time and place, diverse in modus operandi, and good at camouflage scars, basically leaving no common evidence, to prove this, it takes a lot of manpower and material resources, and it cannot be completed in a short period of time. ”

Min Xue nodded regretfully, not every case will be solved logically, otherwise there would not be so many old cases backlogged.

Thinking of this, Min Xue somewhat understood the meaning of Guan Hongji to show him the file, and maybe had the intention of letting him provide ideas, but the most important thing was not to let him solve the case, but to put pressure on him.

Some time ago, Min Xue's case was too many and too smooth, although there were no signs of floating for the time being, but it was better to prevent trouble.

Guan Hongji wants to ring the alarm bell for Min Xue and let him know that it is not easy to solve the case in criminal investigation!

There is also training, which is not without this intention, all in order to let him sink.
