I grabbed this person's shoulder for the first time, this person screamed in pain, it seems that he was not lightly injured, this person's shoulder is bruised, the flesh on his hands is also scratched very seriously, and there is no scab, if a person is only injured in the flesh, he can barely endure the force, but the muscles and bones are injured, this is not by perseverance, can be forced

His shoulder joints were bruised and swollen, so no matter how hard he tried, he couldn't use much strength, the characteristics of this person's arm injury just matched the shallow but fatal wound on Batu's head, and now there was one more suspect in the most suspicious case, the previous two were people who had no alibi and were close to another side door, and the two suspects overlapped, making them even more suspicious, and the two people had been locked up by Amur

I analyzed Amur, and when Amur heard it, I thought it made sense, saying that this man must have been injured in both hands, but he wanted to kill Batu, so he caused such wounds, and the two side doors were almost completely closed at that time, and Amr and I stood at one of the side doors and could only see Uan playing the piano

At present, according to analysis and speculation, the murderer most likely took advantage of the sound in the hall and the habit of indulging in music and not opening his eyes often when he played the piano, so he entered the hall without knowing it, and walked to Batu's side and attacked him ruthlessly

After Amur listened to what I said, the anger came up again, I grabbed him in time and asked him not to be too frizzy, I told Amur that even if this person meets the portrait of the suspect I described, it may not be able to prove that he is the murderer, and the criminal psychological portrait does not originate from China, although there is no complete theory of criminal psychological portrait in the early days of China, but in fact, since ancient times, the case handlers will still unconsciously use logical reasoning to describe the portrait of the suspect

It's just that the theory of criminal psychological portrait in China is still incomplete, and it can even be said that it is missing, Amur doesn't understand what criminal psychological portrait is, he just wants to know how I can finally determine who the murderer is, Amur spoke with anger, and everyone was frightened

I thought about it, and said that there should be direct evidence and motive for the crime, and then I looked at the man with the injured arm, and I asked everyone how this person usually had a relationship with Batu, and everyone said that Batu was regarded as a bully in Gacha, but although he was indifferent to his subordinates, he basically didn't fight hard, and he gave them enough wages and food money, which was very good to them

If there is no conflict, it can basically be ruled out that it is a vendetta, in addition to vendetta, it is nothing more than killing for profit, wanting to kill and killing without purpose, the so-called profit killing is to see profit, such as robbery and killing, it may be that he wants to get something from Batu, it may be money, it may be status, or it may be the people around Batu, such as Wu'an

Assuming that it is profitable, the murderer cannot do it at this time, because at this time, not only will he not be able to get what he wants, but he may also expose himself, and it is only wisest to kill Batu in the dead of night and take Batu's money

I was wondering if it was for the sake of killing, but soon this possibility was basically denied by me, and the reason was basically the same, even if the murderer killed Batu, he would not be able to get Batu's status, money or woman, how could Batu have the rights and money casually give people Batu's death, and the only person who could get all his property was Amur alone, and this person was always by my side, and it was impossible to kill

As for purposeless homicide, it generally refers to the crime of homicide committed by people who are psychologically deformed, mentally abnormal, and simply to satisfy their own perverted desires, and this crime involves a wide range of motives, and according to the current clues, there is no way to determine that the murderer killed for this purpose, but there is no evidence to deny it

After thinking about it for a long time, I didn't come up with a motive for the killer to kill Batu, I sighed and asked Amur to lock up this person first, and Amur grabbed this person by the collar and said that it was better not to let him find out that person was the murderer, otherwise he would be dismantled

After getting angry, Amur asked him to lock up the man, and I told Amur that I was going to interrogate the three locked suspects later, as if to see that I had analyzed some clues, and Amur listened to me more now, and finally he asked me what I was going to do, and I thought about it, and took the heavy dagger in my hand and watched it carefully, and asked Amur to carry Batu's body away first and seal off the hall

Just as everyone was about to walk out of the hall, I stopped abruptly, and I wondered why the dagger was so heavy, and I looked up sharply, and I looked up directly above where Batuu's body was, and I told everyone to hurry up and bring the ladder, and I had been in the hall last night, when the hall was almost set up

But there was a ladder leaning against the hall at the time, and I almost knocked it down, and it stands to reason that the hall was almost arranged, and that the ladder of that size had been lifted out of the hall so as not to get in the way, that I suspected that someone had used the ladder to manipulate the top of the hall last night

The dagger is very likely to be a free fall, the falling dagger is very heavy, coupled with the height of the hall, the free naked piercing into Batuu's head can definitely cause a wound that is not deep but enough to be fatal, the length of the dagger itself is not long, but the density is large, the mass is large, I have been thinking that this dagger is not a convenient killing tool, but I did not think that it is very likely that this dagger is the most convenient for the murderer's killing strategy

The end of the dagger near the tip of the knife is very heavy, and the end near the handle is very light, which can completely ensure that the dagger will always keep the tip of the knife down when falling, the more I think about it, the more wrong it is, and I suddenly remembered the ghost crying table

In the ghost screaming meal case, the murderer Li Deshui killed Fei Ji at the police Fei Ji's house because he used tools, that is, the magician is best at making invented props, I wonder if this case will actually be the murderer did not approach Batu at all, but used some kind of props and mechanisms to let the dagger fall freely into Batu's head

I told everyone not to leave this hall, Amur knew that I must have found something, and immediately moved the ladder over, I didn't ask anyone to help, just for fear that the murderer would fish in troubled waters at this time, and remove the traces of the mechanism, everyone was under Amur's surveillance

As long as there is a mechanism, there will inevitably be traces of the mechanism, since the murder happened, we have hardly left here, the only time to leave is to follow Amur to find the dark clouds, but that time is too short, everyone is walking around, the murderer cannot have time to go to such a high place to get rid of the traces of the mechanism

Assuming my assumption is correct, the dagger probably fell directly above where Batu was lying, so there must have been something on it that could hold the dagger in place, such as thin wire, super glue, etc., to prove that my guess was correct, and there were several iron railings directly above the position where Batu was lying, which was the original structure of the roof

However, the interval between the iron railings is several centimeters, and if the dagger is to be in free fall, it should be kept almost downwards when it has not fallen, at least roughly maintained, if it is horizontal, the position will be deviated when falling, and it may not be able to kill Batu, if the murderer really uses the mechanism, it must be carefully calculated, and he will not do risky things

But if the tip of the knife was downward, the railings were too far away to jam the dagger and let it hide on the roof, so I searched carefully and tried to find something like a string that would hold the dagger, but I was disappointed that I found nothing

I had people move around the ladder and the speakers placed in the middle of the hall to make sure I searched almost the entire roof, but still didn't find any signs of a mechanism
