The matter on the side of the Martial Arts Association, after a quarrel between Ding Fan and Kong Jie, the matter came to an end temporarily.

Although the cause of this incident is a little disgraceful, the final result is not bad, at least after doing something illegal, these people will stand up and bear their due legal responsibility, and it does not conflict with the law, and the result is acceptable.

When Ding Fan was about to go out, Kong Jie sat on the chair, looked at the table that was broken up, sighed, and shouted at his back, telling him to remember to go back and compensate for his table.

Although the table was a little worn, it was originally usable, but now it was completely beaten into a broken table by Ding Fan's punch, and even the broken one had no value left at all.

Of course, no matter how he shouted, Ding Fan didn't even mean to turn around and talk to him.

As soon as I went out, I saw Huang Yao and Fu Lei coming back from outside, looking at the sweat on the faces of these two people, it was obvious that they had worked hard enough outside!

I just don't know if these two people have found anything outside, I hope they don't be the same as Miao Hui before.

As soon as the two entered the door, they immediately saw Ding Fan coming out of Kong Jie's office, and the two hurriedly stepped forward.

Come on, looking at the appearance of these two people, Ding Fan is relieved, their investigation is effective, but I don't know if the clues they brought back will be related to this case.

"Ding, we've got the news here. ”

"It's really like what Ding said, we investigated the medical school for an afternoon, and there really was one person who met the criteria, but this person has already left the school and now happens to be a doctor. ”

Huang Yao said as he took out a bag of information from his pocket, which contained the detailed information he had brought back from medical school.

It seems that today's investigation of these two boys is quite smooth, and the things they brought back can be regarded as relatively satisfactory results.

Ding Fan took the thing in his hand and quickly flipped through it.

This time, the suspect information brought back by the two is indeed quite complete, the suspect's name is Du Haichao, he graduated from medical school three years ago, and during his previous time in school, it can be said that he is excellent in character and learning, and the professional courses are even better in the whole school.

After graduating, he successfully entered the hospital, and now he is a well-known surgeon in the whole Binhai, and he is relatively famous when he was in school, and he has even been used by the school as a typical student to educate new students for many years.

However, there is a not very serious stain on his file.

This was written on it by Du Haichao's mentor at that time, maybe if you change the teacher, you won't write it on the file at all for this kind of trivial matter.

On the contrary, Du Haichao's tutor is a bit old, he still came down from the army back then, and it took a lot of effort from the medical school to invite people over, and there are not many students with him, and this Du Haichao is one of them.

This old man is an old revolutionary, and he never tolerates things that he can't see.

Maybe this is also the only small flaw of the old man, although he is not right about things, but he is too serious about things, and many professors have been sprayed by him I don't know how many times.

"Fortunately, there is such an old man, if it weren't for his old man to speak, I really don't believe it. ”

"You two won't treat people as suspects just because of the word cat abuse written on this file, right?"

Fu Lei also eased up a little at this time, grabbed his hair and laughed a little embarrassed.

"Actually, we really had that idea at first. ”

"But we did find Du Haichao's teacher back then, and after confirming this matter, we investigated this person in detail. ”

"As a result, we found that this doctor named Du Haichao collided with the few points given by Ding today, isn't this still suspicious?"

If the truth is really like what Fu Lei said, this person named Du Haichao is really a little suspicious.

It's just that this suspicion is only temporary, after all, judging from the current clues, this Du Haichao and the victim Liu Yuanxiang don't seem to have any superfluous connection, if these two people don't have a point of contact at all, then this murder case will be difficult to establish.

"Unless it's a serial murder, these two people should be somewhat sociable. ”

"Otherwise, it would be difficult for this case to be established, and there would be no way to close the chain of evidence. ”

"Of course, there are some psychopathic situations, but this kind of person often commits crimes more than once, I have seen many case files, there are many such cases abroad, but there are very few in China. ”

These two people have not experienced any cases before, at most, they know some things in textbooks and cases in school, as far as they know, it is really a little little, and this kind of case, just heard of a typical case, in fact, can not play a very big role.

It's like the case of this serial murder case that Ding Fan said, the two of them have basically never heard of it.

Hearing Ding Fan's words at this time, both of their eyes lit up, and they were eager to know something in detail.

As soon as Ding Fan looked at these two people, he understood what these two people meant.

While there is still time, I simply talked to these two people.

To put it simply, some foreign experts have done some research on the case, and of course they have also made some statistics, generally speaking, the murderer who is finally found in a perverted homicide case will often have three characteristics.

The first is bedwetting, and many people will wonder why these crazy executioners have such a problem as bedwetting.

In fact, this problem is generally based on the childhood memories of these murderers, who were oppressed in childhood or violently abused, causing these children to have some frightening dreams when they fall asleep, and it is not surprising that they wet the bed.

Foreign criminal investigators have done a more comprehensive investigation and statistics, and found that these prisoners are surprisingly consistent, and they all have very similar experiences in childhood.

The remaining two characteristics are that these perverted murderers have a history of arson and animal cruelty, and the first problem may be due to a lack of love.

But then these two problems are entirely caused by the oppression and liberation of life and retribution.

People who don't have any control over their own lives or lives will accumulate a lot of irritability in their hearts, and they desperately want to release the pressure in their hearts through various means and all means.

And fire and the abuse of some animals that are powerless to resist are the best options for them.

The aggressiveness of the flames is more like their hearts at that time, full of mania and desire for destruction.

Through arson, perhaps they can release their inner desire to have nowhere to vent and complete the catharsis of this desire for control.

Not to mention the cruelty and killing of animals, the pleasure of overriding the supremacy of weak lives and being able to control the life and death of other creatures at any time is also a form of catharsis.

It is these three points that basically constitute the three most basic characteristics of a psychopathic murderer, also known as MacDonald symptoms.

And from a psychological point of view, a young child who has the courage to face blood and dare to kill weak animals often has the courage to kill a person when he becomes an adult.

It is very famous that there is a murderous demon known as a clown abroad, who has committed many crimes without being discovered in just six years, and in six years, thirty-three fresh lives have fallen on his hands.

This kind-looking little fat man had excellent grades in school, and he was also a well-known figure in the local area, an excellent sales employee in the company, and an outstanding vice chairman of the Junior Chamber of Commerce.

He is polite to his neighbors, and often organizes some charity donation activities in his spare time, dressing up as a clown in the crowd to please the children brought by the guests.

But no one would have imagined how hideous this friendly and cute fat guy would be under this funny clown mask.

After a drinking party, the clown, as usual, with a mask, lured the two young children to walk towards the small forest not far away, intending to do something wrong.

Unexpectedly, the two children struggled violently, and one of them, who was a little older, broke free from his restraints, fled from him quickly, and told his family about it.

Only then did the police discover his long-hidden true face, and after this incident, the police's investigation of his family began.

More terrible things have also slowly surfaced from this investigation.

After the police investigation, four corpses were found in the garden of the fat clown's house, and twenty-nine corpses were found under the bridge near his house.

Thirty-three lives were strangled to death by this seemingly kind little fat man with a tourniquet.

This file was viewed by Ding Fan when he first arrived at Interpol, because this case is very representative, and the time when it happened is not long ago, so Ding Fan still has a very clear memory of this case at that time.

It's just that after the situation of this case was finished, Huang Yao and Fu Lei obviously hadn't come to their senses, and their bodies were still shaking from time to time, as if they were frightened by the content of this case.

After a long while, Huang Yao reacted, slowly looked at Ding Fan and asked, "Thirty-three people, are they all people he doesn't know at all?"

Ding Fan nodded, recalled the data of the previous case file and said: "Thirty-three men, without exception, have no contact with his life, and the murder weapon is a blood-stained tourniquet. ”

"Do you know why he chose this tourniquet?"

Because this tourniquet was used when he was a child, he was tied up and beaten by his father, who had been an alcoholic for a long time. ”

When Huang Yao heard this, he almost vomited on the spot, frowned tightly, and gritted his teeth, obviously at this time, he had not recovered from the case record just now, I am afraid that the scene has appeared in his mind at this time.

Fu Lei was a little better than him, although it was a little late to come to his senses, but at this time, he thought that he had almost digested it.

"This is the shadow of childhood that Ding just mentioned!"

"Maybe this clown also wets the bed, but it doesn't seem to say anything about killing animals!"

It seems that Fu Lei and Huang Yao's focus is still different, he has been inserting the three elements that Ding Fan just said, and has not analyzed the case too much.

"When I say animal cruelty, I don't just mean those kittens and dogs, but all creatures with low resistance ability, including ...... Person. ”

"There were 33 victims, at least half of whom were minors, and after his confession, these people were all drugged by him before they were killed, and their ability to resist was limited. ”

Fu Lei nodded thoughtfully, understanding that this so-called three elements are not fooling people.

"Okay, I'm telling you about this case just to make you understand that once it's determined that this person has a psychological problem, it's best to follow up with the investigation immediately, because such murderers often don't kill only one person, their motive for killing is completely uncertain, and even killing people has no purpose at all. ”
