Chapter 21 Chapter 21

His knife was placed on Lao Zheng's chest, and the blood stains printed the general appearance of the knife on Lao Zheng's chest. I don't know what kind of knife it is now. It is not a scalpel commonly used by doctors, nor is it commonly used by butchers. My meat cleaver is not even a chef's kitchen knife, but I can draw a picture of this knife and leave it to someone who knows how to identify it.This knife is not big, with a single edge and a sharp tip. The edge of the knife on Lao Zheng's body fully fits these characteristics. But he was still not professional enough, he didn't know, such a short time was not enough for that evidence to enter Lao Zheng's stomach, it just stayed in the esophagus, so he didn't get what he wanted.

I believe that the murderer's next step may be to tear Lao Zheng into pieces.He's gone completely insane.But the police assistant rushed over at this time, and he had to run away again. I stared intently at the evidence that Lao Zheng guarded with his life. Louis Vuitton. It was a Louis Vuitton button, and I couldn't tell if it was real or not, the famous luxury brand has been counterfeited too much, especially for leather bags.Does this brand also make clothes?I don't even know. The best consultants are obviously the brand's boutiques.The buttons have been washed and put in an evidence bag.The person in charge of the store quickly determined that it was genuine and that it had been ripped from the sleeve of a blazer.I was surprised when I saw this casual suit. It turned out that my grass-green light-striped corduroy casual suit was a fake Louis Vuitton of the famous international brand.The same fabric, the same style, but I bought it during the National Day sale, 300 yuan, and this Louis Vuitton, more than 70,000 yuan.

I am very excited, not everyone can afford such a price, and no one will bring 70,000 cash to buy a piece of clothing, so as long as we check the transaction records of the specialty store, we can have the account number and signature of the payer, We can get more detailed information at the bank. My heart was pounding, we had never been this close to this murderer. After 4 days, we found the information of all the clothes buyers.The death of Lao Zheng made everyone excited, and everyone worked with unprecedented efficiency.Except for two who do not have bank accounts in this city, the rest are from the city's population. These 25 people were found out one by one, and 7 of them are not in the country. They have immigrated or went abroad for investigation and business negotiations.One of the seven people is a pair of brothers. They just exported their labor services abroad to be chefs two days ago. Before going abroad, they each bought one. The salesperson still remembered their appearance. We made their portraits according to the salesperson’s dictation. Their suspicion is too great.Of the remaining 18 people in China, two are in the catering industry and one is a surgeon. Their possibilities are not small.

Who is it?Everyone is thinking hard.The two chefs who went abroad were helpless for a while, the evidence was insufficient, and we couldn’t even pass the Interpol investigation. Most of the chefs who stayed in the country were influential figures, and we couldn’t arrest them all and draw blood one by one. DNA test? The investigation was once again at an impasse.Everyone was lost in thought, and everyone believed that this must be the last darkness before dawn.Where will the light of dawn appear? I'm also thinking about it. For me, the most worrying question is, do I understand what Lao Zheng wants to say?

I was in the office that day, replaying the whole process of Lao Zheng's murder over and over again in my mind.Stop, rewind, slow motion, this movie has been repeated countless times in my mind.When the carotid artery was cut open in the back of Lao Zheng, the belt suddenly got stuck. I always felt that there was something wrong here that I didn't understand.The camera remained motionless for half an hour, and the sweat dripped from my forehead. "Xiao Rui, let's go!" I yelled suddenly, only to realize that Xiao Rui was no longer here, and I was the only one left in the office.I smiled wryly, and pulled Wei Cheng out of the lab who was fuming his fingerprints.

"What are you doing?" Weicheng was still at a loss when he arrived at the scene of the murder. I squatted down and followed Lao Zheng's posture at that time.Everything at that time seemed to reappear in front of my eyes immediately, the female corpse in front of me, and the dim environment.Suddenly, I felt a pain in my neck and I turned my head to look behind me. By the way, this is it!It is the unfinished building, and this is what Lao Zheng wants to say. I pulled Weicheng and ran.It was only when he reached the unfinished building that he explained to Weicheng, who was out of breath.The murderer was interrupted by the police assistant, and he left with a knife. He should have a place to hide before Lao Zheng came.Judging from the fact that he was still wearing a suit in the summer, this place was not far from the main road or his car.It is likely that his car was not turned off and the air conditioner was still on.He launched a surprise attack from behind Lao Zheng, and the most suitable direction in this direction is only this unfinished building.

The unfinished building has built more than ten floors, but it has not been capped. It is very likely that it will never be capped in its lifetime. The grass in front of the house is already knee high.Weicheng and I went around a long way before we found the gate, but the iron lock was already rusted, and there was no sign of the management staff, so we had to turn over the gate. The direction is very clear, it must be towards the scene where Lao Zheng was killed. The murderer needs to find a place where he can hide himself and see the scene.Soon the second scene was found, where the grass had been trampled down, and the place where Lao Zheng was killed could be easily seen through the gaps in front of the bamboo building springboard.The largest gap can barely get out of it.

That's it.Weicheng extracted suspicious footprints, although the rain made them unclear.I also found a cigarette butt, which I believe should belong to him, although the heavy rain these days makes me not sure if I can extract enough DNA.It will take at least tens of minutes for Lao Zheng to arrive, enough for him to smoke a cigarette. He also took a shit, a nasty pile of shit.The rain has washed away the shape of that pile of shit, but it's right where he's camped. The rear of the two footprints. All the evidence was gathered together, and a case-solving discussion meeting was held, chaired by Bureau Wang.Weicheng and I provided the latest suspicious evidence, and everyone spoke freely to study all possibilities clearly.

There is basically no doubt about the process of Lao Zheng’s murder. Everyone agrees with me. After all, Lao Zheng cannot swallow a button without incident, and he will never buy such an expensive suit.The investigation team also found out the knife used by the murderer. It was a carving knife, which is often used by art students. But how to explain the newly discovered evidence by Weicheng and I, everyone fell into silence for a while.Cigarette butts cannot extract dna, and we have no way of confirming whether the pile of shit was made by the murderer. Maybe this is just a coincidence.Everyone was smoking cigarettes, and the discussion room fell silent for a moment.

"Let's talk. Everyone talks about their own ideas. It doesn't matter if you say something wrong, we don't arrest people based on this, what do you think?" Wang Ju deliberately activated the atmosphere, but looked at me. "You found the evidence, why don't you talk about it first." Wang Ju saw that everyone was silent, so he ordered my general. I cleared my throat: "We found several pieces of evidence in this place. Two incomplete footprints, a cigarette butt, and a pile of shit." Someone couldn't help but chuckle when talking about a pile of shit. I too paused.

"Let's consider these as being left by the murderer for the time being, and see what we can get." My eyes scanned the venue, and the venue suddenly fell silent, so quiet that I could hear my own breathing. "What's the height you calculated based on those two shoe prints?" I didn't continue and asked Weicheng. "Yeah." Weicheng also coughed, cleared his throat and said, "The two shoe prints are incomplete, exactly one forefoot and one heel. Subtract the overlapping patterns, and subtract the enlargement between the heel and the foot of the leather shoe." Partly, according to the formula, the person who leaves the shoe print is between 1.55 and 1.60 meters tall." I heard a discussion among my colleagues, maybe this height is a little too short for everyone's imagination of a murderous demon. "I believe the shoe prints were left by the murderer. The only place to hide around the scene of Lao Zheng's murder is the unfinished building, and this place is the most convenient place to commit crimes. I can be sure that the murderer is not tall, because," I suddenly After taking a sip of water, I also calmed down my excited emotions, "The gap that can pass through the wall is not big. With my height, I have to crawl through it!" The discussion below became louder.Everyone got a little emotional, and obviously I convinced everyone.I didn't wait until the discussion was over before continuing: "I can't be sure whether the remaining cigarette butts and the shit were left by the murderer, but if we consider that they were left by the murderer, we can draw a few conclusions: One," everyone's discussion suddenly quieted down again, and I continued: "Cigarette butts are a brand from a certain province in the south. You can buy them in our city for 22 yuan a pack, but the sales volume is not large. Our city likes this brand There are not many people here, unless they are foreigners from that province." I said the name of the province. "Looking at the price of these cigarettes, they are not affordable for homeless people or migrant workers who care for unfinished buildings, but they are basically in line with the murderer's consumption habits. I believe that it is very likely that the murderer left behind!" The voice, the discussion below rang again, and it became louder and louder. "The poop at the end was probably left by homeless people or people who don't pay attention to hygiene. But if it was left by the murderer, I believe he was not nervous. Because there are too many places for convenience in that unfinished building Yes, just take two steps. But the murderer can not care about this stench, which shows that although he is in a good financial situation now, he was not rich in his early years, and he may even have the experience of vagrancy and begging!" There is an exclamation below!I know that the colleagues in the investigation team have accurate suspects!My eyes turned red, and only then can I truly believe that Lao Zheng did not die in vain. Based on all the information provided by the evidence, the suspect was identified at the meeting.This person was unfortunate in his early years, his parents died, he used to be a vagabond and beggar, and the cigarettes he smoked were from the province where he was born.Later, he gradually made a fortune by reselling gutter oil, and now he is the president of a restaurant chain group. He also has the unique skill of food carving, and has won many awards in competitions. No one around him believed that he did this, and several employees even came to the Public Security Bureau to complain.Weicheng said angrily that this person wore a mask too well. I didn't reply, but I was thinking in my heart who in this world is not wearing a mask to be a human being?Xiao Rui wears a mask, she is used to hiding her pain; Lao Zheng wears a mask, he is used to solving all the difficulties by himself, it may not be a good thing not to ask for help in his life; I don’t wear a mask too Well, in the eyes of others, I am tough and sunny, but only I know the pain in my heart. I regret that Lao Zheng never called him Uncle Zheng when he was alive, and now I have no chance to call him Uncle Zheng again. That damn "Aiqu Sanou" nickname made me regret it so much that my stomach was green. The suspect was even more cunning than we imagined, and he resolutely refused to make any confession, even in front of DNA evidence.He hired two well-known barristers. These two lawyers began to try various ways to intervene when the case was still in the investigation stage and had not been handed over to the prosecutor's office. These two big states are really not vegetarians, they have questioned all the evidence, even DNA evidence.They started to nitpick from the layout of our laboratory, and then questioned the experimental equipment and the DNA extraction process step by step.I was also secretly surprised, they are really experts, and our funds are limited, and the laboratory layout and experimental equipment are all qualified, so we still have to invest millions of dollars. We are just crude and simple. In addition, we can send the inspection materials to qualified provincial departments for re-examination. Even if I get it from the Ministry of Public Security, I am not afraid, and I have confidence in my results.But this guy's hands and feet are so clean, we all thought we would find them in the bathroom, but in fact there was nothing, we searched for the sewers and tile seams, but there was nothing.The blood tracer we commonly use can reveal bloodstains that are even diluted to one ten-thousandth, and I wonder if he was dismembered in this room. What should we do? Could it be that the matter has come to this point, we can't sue him, and we want to watch him slip away from us?never! I have always had the idea of ​​meeting this man, just to see what he looks like.This opportunity finally came, and the guard asked me to go to the case, and I saw him. He didn't look vicious, and was even amiable. I was walking with several cadres of the detention center, and he turned his head and said to me: "Hello." The "hello" made me shudder.I don't know him, and I'm sure I haven't seen him before. Why does he know me like an old acquaintance? Under pressure from the police in the detention center, he finally revealed the truth.After killing Lao Zheng that day, he still didn't get the button, so he didn't leave.When I went to see Lao Zheng, he was still hiding in that unfinished building. This is called Tianwang Huihui, sparse but not leaky.He couldn't help being proud when he saw me——I killed your colleague, and I hid in the dark to observe you, didn't you notice it at all?It was this kind of complacent attitude that made him show his fox tail, and finally couldn't bear the pressure of the interrogation, and confessed the process of committing the crime.
