"Professor Li, is he the murderer?" Adiri asked me in surprise.

I looked at Adili: "What's the matter, isn't it possible?" ”

"But not long after you chased Maiti into the desert, he went into the desert with you, didn't you say that he saved your life from the sand depression?" Adiri asked.

I walked slowly towards Uncle Man, who was at the back of the crowd, and he stood motionless. I stared at Uncle Man and didn't look at Adili, but my words were to Adili: "Don't you understand it until now, Maimaiti has already died, and the person we have been chasing is not a so-called ghost, let alone Maimaiti himself." ”

I walked in front of Uncle Man and said to Uncle Man in a deep voice: "Do you dare to extract fingerprints for comparison?" ”

Uncle Man frowned: "I didn't kill anyone, I refuse to do fingerprint comparison." ”

I scoffed, "No one can hide it." To prove your innocence, you have to do it! ”

Adili was not polite to me, he immediately took out his gun and aimed it at Uncle Man. There was a threat of gunpoint, but Uncle Man did not resist, and several other criminal policemen held Uncle Man's shoulders and escorted him to the table that I had prepared in advance. On the table are some paper and graphite powder for fingerprint extraction.

There are many methods to extract fingerprints, and graphite extraction is the most commonly used and effective physical extraction method. After extracting the fingerprint, fix the fingerprint on the paper, and the lines and fingerprint features on it will be clearer. Fingerprint comparison is the process by which professionals identify two fingerprints to find similar connections.

Fingerprint comparison is not an easy task, and it is necessary to have sufficient expertise. When the connection points and lines of the two fingerprints reach a certain degree of similarity, the fingerprints can be considered to be the same. Although the tools on site are simple, it is still possible to do preliminary identification by using the most primitive methods.

Adili and the criminal police forcibly extracted the fingerprints of Uncle Man's index finger with graphite, and immediately, I began to fix the fingerprints and compare them. The scene suddenly became very quiet and no one came to disturb me. Looking at Adili again, he still pointed his gun at Uncle Man, and everyone was very wary of Uncle Man.

After the fingerprints were fixed, I began to compare them carefully. There were not many people present who still had professional knowledge of fingerprint identification, and Adili knew a little, but he was not particularly professional. I called Adili over and explained it to him, one connection point at a time. With my explanation, Adiri contacted what he knew, and soon understood.

The fingerprint comparison was completed, and I stopped what I was doing.

"The fingerprints on the dagger are the same as yours, Uncle Man, do you have anything else to explain?" I asked.

Uncle Man gritted his teeth: "I didn't kill anyone, how can you be sure that this dagger is the murder weapon that killed Maimaiti!" ”

I asked rhetorically, "Then you explain, how can a dagger with your fingerprint appear near the crime scene?" ”

Uncle Man couldn't answer, so I smiled coldly: "You still have a fellow party, confess." ”

Uncle Man: "There is no killing, there is no comradeship, what do you want me to offer!" ”

Adiri took a sip: "The physical evidence is placed here, and you are still quibbling!" ”

The villagers were stunned for a moment, and Adili immediately told everyone the results of the fingerprint comparison in the provincial dialect. However, there was also obvious confusion on Adili's face.

"Professor Li, didn't you say that you want to use two clues to solve the case? The clue is this dagger? Adiri asked.

I shook my head: "This dagger is the third clue." ”

Adili: "What are the first two clues?" ”

I replied with a smile: "One is called luring the enemy, and the other is called catching the enemy." ”

Adiri was stunned for a while before he reacted: "The clue is fake? ”

I nodded: "That's right, the clue is indeed fake. ”

I analysed Adiri's intentions. In fact, the desert is so big, and there is yellow sand everywhere, how can I find a clue in the desert? The reason why I told the whole village that there were clues in the desert was just to lure out the people who were following me.

It is precisely because of the mystery of the desert, coupled with my vows, that the other party is not sure whether I can really find clues, so they follow me into the desert with a weak heart, in fact, all this is just my psychological strategy. I knew that even if I lured the other person out, I wouldn't be able to catch him, so I deliberately put yellow sand in the black bag.

I wanted to use the black bag to lure the other party to my room to steal clues, but I didn't expect that I lay down all night, and the other party didn't appear. I calmed down in time and simply took the plan and told everyone that the clues in the black bag were fake.

The black bag is yellow sand, and when Maimaiti adjusts the bag, he will definitely speculate that he has been fooled. But when I said this, Maimaiti was unsure, so when I said that I would go to the graves to look for the second clue, Maimaiti followed me with a weak heart, which allowed me to find the flaw.

The first time it was just to lure Maimaiti to appear, and the second time I was sure that Maimaiti was one of the murderers.

"Thanks to Doha this time." I said to Adili, nodding at Doha, who was sitting in the crowd.

Adiri was puzzled, and I explained it to him again. Yesterday, I found Doha, and I gave the dagger to Doha and told her that this was the real clue. When I told Doha about the fake clues, Doha was also very surprised. As for what I asked her to do, it was to ask her to keep the third clue for me.

When I return to the village this time, I am bound to catch the real culprit. When I left the village and returned to the village, the killer was definitely suspicious of me, so I was worried that the killer would do everything he could to snatch any clues I had. Just in case, I put the dagger at Doha's.

"Important things, I usually put on my own body, and the murderer must not have thought that I would put someone else there, so, during the time when I asked people to prepare graphite, I found a trustworthy person and put the dagger in Doha's place." I said to the crowd, "However, it seems that I was overly worried, and the murderer did not come to me, nor did he go to Doha. Right, Doha? ”

Doha immediately nodded, "Yes." ”

Me: "Doha, this is a matter of several lives, and you must make sure that the dagger has not been transferred." Once confirmed, Uncle Man will be arrested by the police and identified as the murderer. ”

Doha: "I'm pretty sure I can't be negligent about what you told me, so I didn't close my eyes all night. Captain Adili, I can prove that this dagger is the one that Li Ke handed me yesterday. ”

Adili nodded: "It hasn't been opened during the period, right?" ”

Doha: "Haven't opened it. ”

I had already instructed a criminal policeman on the side to make a record of the scene. Adiri slapped his big hand, his face was full of joy, he walked up to me, and said that the case was finally going to be solved. Adili asked people to carefully put away the fingerprints fixed on the table, and Uncle Man, he was also controlled by two criminal policemen.

Although the criminal police were very vigilant, Uncle Man had no idea of resisting at all. The villagers were still in shock, and they didn't seem to believe what had just happened. I have also inquired before, since Uncle Man returned to the village, he has not often dealt with the villagers, at most he has intersected with the neighbors.

But in everyone's eyes, Uncle Man is a very friendly person, and he has no entanglement with these deceased, so everyone doesn't believe that Uncle Man is the murderer. Uncle Man is also very well hidden, no one knows that Uncle Man's skills will be so extraordinary.

But after Adiri sorted everything out, he suddenly froze again. He remembered that I had just said that Uncle Man still had a comrade, so he hurriedly asked me who that comrade was, and when he saw that I didn't answer, Adili waved his hand: "Forget it, first arrest people and send them back to the police station for interrogation, so as not to die inexplicably." ”

Adili asked the detective to take out the handcuffs and anklets and prepare to handcuff Uncle Man, but I stopped him.

Adili looked at me suspiciously: "Professor Li, is there anything else you want to explain?" ”

I nodded, "You've caught the wrong person." ”

Adiri was stunned: "What do you mean?" ”

I walked over to Adiri, took the handcuffs from his handcuffs, and walked slowly forward. With everyone watching, I handcuffed one man: Doha.
