Ding Fan had read the book before, and some psychiatrists who had high research achievements in psychology could actually draw the appearance of the murderer with the traces left by some crime scenes.

Ding Fan has always been a little incomprehensible about this, and he wonders if they really have this ability.

Of course, these are just what he saw on the information, foreign research on psychology is relatively long, the technology is relatively mature, there are more or less such people, compared to the domestic contact with psychology is relatively late, for the time being, I have not heard of anyone who has this ability.

Speaking of which, Ding Fan really hopes that such a person exists, and with these people, it may be much easier to investigate the case in the future.

According to the clues left at the scene, the appearance of the murderer can be drawn, and the matter of arrest is followed, and the police force can save trouble.

But I just don't know if I really have this ability, I haven't seen such a person, which makes people feel a little mysterious.

Even Ding Fan has tried to use psychology to do some mental testing and the like, which can be done, but the detailed psychological portrait is a bit difficult, and even the painting is a bit different.

After returning from the nursing home yesterday, Ding Fan had already tried, wanting to imitate the way in the book, make a simple guess, and then make a portrait of the murderer.

But the person who was drawn in the end looked a bit like Yu Xiaobo, and his body shape was almost the same, but why is this face always inseparable from these people around him?

In the end, Ding Fan could only give up, planning to go to the forensic doctor's office and ask about the situation over there.

As a result, when he came out of the office, he saw Captain Niu coming out of the office of the Zhou Bureau dejectedly, and these two people had just met each other.

The Niu team was obviously just cleaned up at this time, and they were uncomfortable at this time, and when they didn't have the face to see people, they saw Ding Fan coming towards them, and they turned around and wanted to go back.

However, Ding Fan couldn't tell him to leave like this, so he hurried two steps to catch up, took a cigarette in his hand and sent it to the cattle team, and said with a smile: "Smoke one, the report over there is finished in the Zhou Bureau?"

In fact, Ding Fan knew that Captain Niu must have just been kicked out by the Zhou Bureau at this time, and he was scolded very miserably.

He also came out of the captain of the criminal police back then, and after the director was cleaned up by the leaders above, he inevitably brought the captain of the criminal police over to clean up.

When he was under Ma Longfei, although there were few such things, they were not completely uncommon.

So Ding Fan understands him very well at this time, so taking advantage of this time, smoking a cigarette is the best way to relieve him.

is the so-called stretch out your hand and don't hit the smiling person, although the bull team is not in a good mood at this time, Ding Fan didn't come to mock him, at this time, he was angry in his heart, and he couldn't treat others with a cold face, so he stretched out his hand and lit a cigarette, stood by the window, and took a hard puff.

"I know that you are aggrieved, when you encounter this kind of case, in fact, I understand you, three murders in a row, whoever puts it on it, will feel a lot of pressure, ordinary people encounter this situation, I'm afraid it has been crushed, but we can't boast, whoever told them to do this business!"

The two stood by the window and smoked, and no one spoke at the beginning, but the Niu team didn't speak, and Ding Fan couldn't wait.

If the murderer is caught a minute earlier, there will be less danger for the people outside.

This time, the murderer will not stop like this, and it is very likely that he will commit a crime again.

At this time, it is definitely not the time for internal intrigues, even if he knows that the Bulls team is a little disdainful of himself, he has to say some things first.

And the Niu team is not an unreasonable person, at this time, it is the most important thing to unite all the forces that can be united, even if it is not looked down on, it is also a matter after the case.

Especially when Ding Fan said this, he couldn't do anything with him, otherwise it would seem that he was too small.

"I also know that if this case is not dealt with early, there will definitely not be only these three people who will die in the end, and I am afraid there will be more later. But now I can't help it, the case has been taken over by your task force, and we can't intervene at all. ”

"It's not that I don't like you, I don't have a grudge against you, I haven't met before, I can't say that I have any grudges, but because of this case, we have been investigating for almost half a month, and in the end we found nothing, so I can only transfer the case to others, I just hate myself for not being angry. ”

Speaking of which, isn't this still a hurdle in my heart?

said so much, it is nothing more than to express a meaning, that is, he wants to continue to investigate this case, and he doesn't want to leave regrets in the end.

If he wants to talk about other things, Ding Fan may have to think about it, but he simply wants to join the investigation team, which is not a bad thing in itself.

After all, there are not many people in the task force itself, and if you want to investigate a case, in addition to the necessary criminal investigation methods, you actually need some police officers who know the case to join in.

Otherwise, it will take too much time just to understand the facts of the case, and if there are local police officers involved, it will naturally only be beneficial to the investigation of the case.

"I have the final say in this matter, you can bring someone to join the investigation team, I will call someone to say hello to the Zhou Bureau, you can transfer the manpower now, and we will have a meeting later to discuss the matter of this case." ”

After saying that, Ding Fan didn't care about Captain Niu's current look, turned around and walked towards the office of the Zhou Bureau.

The two discussed in the office for a while, and finally walked out of it together and went directly to the conference room.

At this time, in the conference room, Captain Niu had already waited inside with a few of his right-hand men, and when he saw Zhou Ju coming in, he immediately got up, but Zhou Ju stretched out his hand and signaled them to sit down first.

"Ding has already told me just now, this time the case is very tricky, since Ding has said that you want to use the investigation, then I won't say anything, you have all remembered for me, do your best to use this investigation, I don't care what means you use, I must know that the murderer is not allowed to provoke the law and discipline of the country. ”

Director Zhou has never had such an emotional outburst as today, and it is also this case that completely angered this good gentleman, and the words he said in anger were a bit loud.

"Don't say anything else, notify all departments, come over for a meeting, the autopsy on the forensic doctor's side has already come out!"

Ding Fan stretched out his hand and motioned for everyone to sit down first, and then asked the forensic doctor about the news.

Captain Niu has already gotten the news from the forensic doctor, but the report that can be archived has not yet come out, after all, it takes a certain amount of time for the drug test to be done, even if he is in a hurry, he can't rush it.

"Most of the autopsies on my side have been completed, and the rest of the drug tests will take a little time. ”

With Captain Niu joining this task force, He Qi didn't have to feel uncomfortable in the middle, and generously took out the forensic report in his hand.

"The deceased Gu Xucheng is eighty-four years old this year, there are only a small number of external injuries on the body, after testing, it is just some scratch marks, and there is a piece of skin on the outside of the left arm that falls off, it should be that under the low temperature at that time, the arm was adhered to the ice, and the subconscious activity was torn off, and there were no other external injuries, the cause of death was blood circulation disorders caused by low temperature, and finally led to heart failure, and the time of death was judged by the gastric dissolution, which should be about four hours after eating on the evening of the 15th. ”

This time, He Qi's introduction can be said to be very detailed, and it looks much more relaxed than before.

"I've seen respect for the elderly before

The recipe of the hospital, the time of dinner is generally arranged at about half past six in the evening, and the time after the meal is four hours, which should be around ten o'clock in the evening, so how long does it take for a person to be fatal in the case of low temperatures?"

The last time Gu Xucheng appeared was in the morning, and he was already gone at lunchtime, thinking that he should still be alive during these two times, and it was obviously inconvenient to go to the refrigerator during the day, only the night was the most suitable.

Then the time of death is after ten o'clock, but in this freezing situation, Ding Fan doesn't know how long it will take to die.

"The deceased died of heart failure, not by suffocation due to icing of the respiratory tract, which is a bit difficult to control, and it is possible to take five minutes, or fifty minutes, depending on the physical condition! Of course, I think the physical fitness of the deceased, it should not be a problem to persist for ten minutes. ”

In other words, the time of Gu Xucheng's death should be between ten o'clock and eleven o'clock in the evening of the 16th.

This seems to be a bit wrong at this time!

"The autopsy report of the other deceased, Tong Lihua, has come out, her body has not been frozen, but she died of a heart attack, but the trigger is because of the fear generated by the confined space, which led to an overdose of adrenaline, and there is no unnecessary injury on the body except for her nails. ”

Come on, this cause of death is simple, and he was completely scared to death.

The murderer's method of killing is no longer as simple as before, but gradually began to torture these victims.

"It seems that the murderer has developed a kind of pleasure after killing for the first time, from the previous quick and direct solution to the victim, hurriedly disposing of the corpse, to the current beginning to kill for fun, there have been great changes in psychological activities, at least now it seems that it is a little difficult to find a reasonable motive for killing. ”

If I'm not mistaken, the killer should have some histrionic personality disorder.

After the first murder, it was clear that his murderous actions had changed somewhat.

From the panic in my heart after the initial killing, hiding the corpse, transferring and throwing the corpse, to now, I am no longer hiding at all, but I have begun to use various equipment or special spaces to kill people in some unexpected ways.

It's like playing a prank on a child, attracting people's attention, using their murderous actions to attract the attention of others.

I'm afraid I'm hiding somewhere, looking at the joke!

"By the way, on the bodies of the three deceased, we have all checked for the residue of sleeping pills, but there is a more or less difference. ”

He Qi has already taken out all the investigation results of the past few days, and the rest of the things can only be seen by what these professional criminal police think.

However, Captain Niu obviously didn't think in this direction, and according to his previous investigation method, he was still investigating the social relations of the deceased.

"Boss, I asked the head nurse between me, she said that in the entire nursing home, it is true that not everyone uses sleeping pills, but some people use them intermittently, Gao Yalin is one of them, and Gu Xucheng had a little insomnia for a while before, and he used it for a while, only Tong Lihua is a perennial user, and the doctor's hand has their dosage record every time, and the medicine storage room, the doctor and the nurse have the key, and the custodian also has two spare ones in his hand. ”

Liu Jian was investigating this matter before, but he had just gotten the news, and he just had the opportunity to report this matter.

That is, there are at least three people who have access to these sleeping pills now.

"Inform the police officers over there, investigate how many sleeping pills are still in the nursing home, and check with the stock they have to see if there is anything missing. Interrogate the doctor and the custodian if they have any borrowed keys. ”
