Whether human nature is born or formed by the environment has not been determined. The ancestors said that the beginning of human nature is good, that is a good wish. In my opinion, at the beginning of a person, it is really difficult to judge the good and evil of his temperament. Personally, my opinion is more towards evil. Because this kind of evil comes from selfish desires and possessive desires, and uneducated people will have extremely strong selfish desires and possessive desires. And the formation of this mentality is innate.

The case I am going to talk about below is the sin of a natural criminal who has a strong desire for selfishness and possessiveness.

This winter, the police received a report from a girl who said she had been robbed and *. This is a case of a very egregious nature, but just this winter, there have been three such cases.

Because the girl was sexually assaulted, I will not give her name here, but only refer to the girl.

The girl cried at the police station, saying that at about 10 o'clock in the evening of November 7, she had just gotten off work from the supermarket where she worked, and when she walked to a remote intersection, a white van passed by quickly, and the people in the car frantically dragged her into the van, wrapped strips of cloth around her eyes, and pressed her face down on the pedals of the van. The girl was then taken to the wilderness, where she was blindfolded, so that she could not see the perpetrators, except that there were about four or five people, and that three of them had raped her.

The girl's purse, mobile phone, gold necklace around her neck and a pair of worthless earrings were snatched. Her black down jacket was also pulled off and thrown in the car. And under the threat of the murderer, the girl revealed the password of the bank card in the wallet.

In the end, the girl was ordered by the robbers to squat in place and not to move, so the robbers abandoned the girl in this barren mountain and fled by car.

The girl was first taken to the forensic center, where investigators extracted the residue* from her body and began to extract and compare the DNA from the *.

During this time of DNA comparison, the girl took us to the place where she was forcibly taken away, and to the wilderness.

The place where the girl was forcibly taken was on the side of the road outside a small community in Loquat Ping, less than 10 minutes away from the girl's home.

Coincidentally, at the place where the girl was taken away, there were surveillance cameras placed by the police. Investigators quickly extracted the surveillance footage.

From the surveillance footage, it can be seen that the girl was wearing a black down jacket with a hat on her back at that time. She was walking on the side of the road, not on the sidewalk.

At 10:17 p.m., a white van with no lights drove up behind the girl. When the van appeared on the surveillance screen, the rear door of the van was always open, and the purpose of this was to make it convenient for the criminals to quickly hijack the girl into the car.

The van stopped next to the girl, and the car was so close that it almost stopped grazing the girl's shoulder. From the surveillance footage, only a pair of hands can be seen stretched out from the car door, which is a pair of very powerful hands, which instantly dragged the girl into the van.

This hijacking took only eight seconds, which shows that the robbers were skillful in committing the crime, and they were by no means the first offenders.

In the surveillance footage, although the license plate number was identified, after verification, although the license plate number was real, the car was a vehicle that had been stolen two months ago. The clue is interrupted here.

The girl took us to the place where she had been raped, which was a three-hour drive from the place where she was abducted.

This is on the side of a remote mountain road in Xiangjia Village. The reason why the girl remembers this place is because on the day the girl was killed, she walked down the mountain road to the Xiangjia community, and then found the police who called the police in the Xiangjia community.

At the scene of the crime, I found two cigarette butts and some toilet paper while looking at the rut marks left at the scene. DNA can be extracted from cigarette butts, and there are residual sperm spots on the toilet paper, which must have been left by criminals. The rut marks are supposed to be those left by the van.

The evidence was sent to the forensic center, which eventually extracted the DNA on the evidence. So compared to the previous DNA in the girl's body, a total of 4 different DNA data were found.

Of these, there are three parts of DNA in *, one part on toilet paper, and one part on cigarette butts. This DNA on the toilet paper matches one of the DNA in *. And the DNA on the cigarette butt exists independently.

This indicates that there were at least four people who committed the crime.

Through the comparison of DNA big data, it was found that the DNA on the cigarette butt was consistent with a person named Liu Zaifeng.

Liu Zaifeng, male, 37 years old, from Cizhu Township, Wanzhou, is divorced. He was sentenced to five years in prison for robbery and wounding in 2004 and has been released from prison.

Then the breakthrough in this case is obviously this Liu Zaifeng, so Lao Lu immediately organized the police and went to Cizhu to track down Liu Zaifeng's whereabouts.

On the morning of November 10, we went to Liu Zaifeng's home in Cizhu. I can only describe this home as a family with four walls, which shows that the owner of this house is living in poverty.

However, this home is not Liu Zaifeng's own home, but the home of his elderly parents. According to the police investigation, Liu Zaifeng has been living with his parents since he was released from prison, because his parents are old, and Liu Zaifeng mostly takes care of the second elder at home. In the eyes of the neighbors, although Liu Zaifeng was a former prisoner, they all thought that Liu Zaifeng was a dutiful son. Many young people here have left their parents and children to go out to work, but Liu Zaifeng has stayed at home to farm and take care of the second elder, which is really commendable.

Sitting at Liu Zaifeng's parents' house, I felt a sour feeling in my heart, looking at this elderly second elder, I really couldn't bear to tell them that their son had committed a sin again.

Just before we could speak, Liu's mother, whose face was full of wrinkles, spoke: "Comrade policeman, tell me, is there another accident with my son." He's been out for a week, and he hasn't even heard from him. When I went out before, I would call the small teahouse next to me every day and ask the old boy in the teahouse to tell us that he was okay outside. But this time is different, it's been a week, Lao Tong said, he hasn't received a call from Zaifeng. ”

I frowned and said, "Old man, did Liu Zaifeng tell you anything when he left?" ”

The second elder looked at each other, but Liu's mother spoke first: "Zai Feng said that he would go to the city for a few days, saying that he was going to earn money and would come back in a few days." ”

I thought that it really only took a few days to make money from the robbery.

I nodded and said, "Do you have Liu Zaifeng's contact information?" ”

Liu's mother said: "The old boy in the teahouse next to him has his mobile phone number, I'll take you there, I want to see what kind of evil this kid has done outside, and led the police to the house." ”

I asked for Liu Zaifeng's mobile phone number from the teahouse owner Lao Tong, but unfortunately, the other party had turned off the phone.

I pulled Lao Lu aside and said: "This Liu Zaifeng went to the city, it should be with this group of robbers and rape criminals, he participated in this case, it should be for money, not for sex, so Liu Zaifeng's DNA was not found in the girl's body." Neighbors said that Liu Zaifeng was very filial, so after he participated in the crime and obtained property, he would definitely return here to honor the second elder. So as long as we wait for the rabbit, we can catch Liu Zaifeng. ”

Lao Lu agreed with my statement, so he sent the criminal police to Cizhu Township to wait for Liu Zaifeng to appear.

But after waiting for a week, Liu Zaifeng still didn't appear, and the phone never turned on, this Liu Zaifeng seemed to have evaporated from the world.

Just waiting is definitely not the way, you must find a breakthrough. Now the only breakthrough is the white stolen van, so I said to Lao Lu: "Investigating this stolen van in the whole district and surrounding areas may be able to find some clues." ”

Lao Lu said: "I started the investigation a week ago, but now there are no clues. ”

It seems that Lao Lu is already one step ahead of me in this regard.

Sometimes, there is always a dramatic turn in the case. And this turn of events is not only dramatic, but more regrettable and angry.

In a mountain col not far from Xiangjia Village, a farmer who cultivated the land found a corpse.

The body was buried in the earth, but not deeply, and there was no camouflage in the burial, so it is easy to see that the place has been turned over.

The farmer who called the police was curious, how could a piece of land have been turned over in this uninhabited place? So I tried to dig a few times with a hoe, but I didn't expect a human hand to be exposed in the soil. The farmer was frightened and immediately reported the case. The corpse's decomposition was not severe, and the time of death was supposed to be less than ten days, but its face was artificially damaged, and it was not possible to identify it.

In addition, the buried man is naked, and it is difficult to identify him visually. I can deduce that the reason why the killer mutilated the face of the deceased and removed his clothes was to cover up his true identity, at least after the body was found, to delay the time for the police to find out his true identity.

The murderer can be said to be extremely cunning and murderous.

I examined the nameless man's corpse and found strangulation marks on his neck, but they were not deadly strangulation marks, but submission strangulation marks.

The real cause of death was as many as seven stab wounds to the back, two of which were directly inserted into the heart.

After examining the body, I looked near the crime scene and found no large amount of blood, but a little drop-shaped blood, which indicates that this is not the first crime scene, but the scene of the dumping of the body. However, due to the abundance of weeds here, there are no clear footprints left on the ground.

But not far from the col, on a rural mechanized road, I spotted a familiar line of rut prints. This kind of rut mark is the rut mark of the van that robbed and raped the girl.

Why did the suspect vehicle come here? It is not far from the scene of the crime where the girl was killed, but it is by no means the only way down the mountain to return to the city, and it can even be said that this road is contrary to the way back to the city. Could it be that the murderer, after committing a crime against a girl, committed another crime along the way?

This possibility cannot be ruled out, and of course, finding out the identity of the deceased is the most crucial.

Now the nameless male corpse has nothing to prove its identity, except that the scar on his left wrist may be a breaking point.

So I took a picture of the scar with my mobile phone, and said to Lao Lu: "This scar should be a knife wound, obviously left in the fight with people, it seems that this deceased is not a good person." Perhaps he was still a former inmate, and his DNA could be found in the national DNA database. ”

Lao Lu frowned and nodded.

The comparison of the DNA data of the male corpse soon came to fruition, and this result was what I call a dramatic turn.

Because this male corpse is Liu Zaifeng in the robbery and rape case.

Why did Liu Zaifeng die tragically in the barren mountains? It's incredible.

Lao Lu looked at the cold corpse in the coroner's examination room of the forensic appraisal center and muttered, "Why did this kid die?" Could it be that his accomplices knew that he had been a prisoner and could easily be found by the police using DNA technology, so they killed people? ”

I also stared at the cold and white corpse and said, "No, the murderer shouldn't think so far, I think there are other reasons." ”

Lao Lu looked sideways at me and said, "Other reasons? Say what you have in mind. ”

I said: "In the robbery and rape case, the DNA we found at the scene showed that there were at least four people, but only in *, there was no DNA from Liu Zaifeng. According to the investigation, Liu Zaifeng has been divorced for many years and has no partner around him, which shows that his desire for sex should be stronger than that of ordinary people. But why he did not participate in the rape shows that Liu Zaifeng is still humane among the criminals, he only acted as an accomplice, but did not participate in more egregious crimes. ”

Lao Lu frowned and looked at me and said, "What does this mean?" ”

I said: "Liu Zaifeng is a filial son in the eyes of his neighbors, and he may need money to honor his parents, so he participated in the robbery. After he gets the money, he should have made it clear to his accomplices that he was leaving the criminal organization and returning to his parents. And the criminal accomplices were worried that their identities would be exposed, so they didn't stop doing it, and killed Liu Zaifeng. ”

Lao Lu said: "It makes sense. ”

Liu Zaifeng's death interrupted the clues of the case again.

But that doesn't mean we can't get started, because there's one more thing I've been waiting for. That's when the killer went to get the money from the girl's bank card.

At this point, the police told the girl not to reapply for a bank card for the time being, because we need to wait for the murderer to appear. And her loss, the police will definitely recover it for her.

The murderer was also cunning and never went to the bank to withdraw money. Could it be that the murderer was afraid of revealing his identity when withdrawing money, so he gave up withdrawing money?

However, I think that the murderer is delaying the withdrawal time, and he may think that the longer it is time to get the money, the more smoothly he will be able to withdraw the money without being detected.

This mentality is obviously a clever trick on the murderer. I think this kind of cleverness is stupid, what if the victim reissued this bank card during this time? Wouldn't the murderer get nothing? Even if he doesn't reissue it, this bank card has been monitored by the police, and even if he goes to withdraw money after 50 years, he will still be found by the police.

Fifteen days after the crime, the murderer did show up. He withdrew more than 12,000 yuan in cash from the girl's bank card at an ATM in Longbao (place name).

From the surveillance screen of the ATM, it can be seen that a man came to withdraw money, and the time of withdrawal was selected at half past ten in the evening. The man was wearing a black down jacket with a cap that covered his head. He wears a blue medical mask on his face. He closed his left eye one moment, and then opened his left eye and closed his right eye. He looked so weird in front of the surveillance probe and frowned at in order to disguise his face. This murderer is indeed very cunning.

But the cunning fox never escapes the eyes of the hunter. And I'm the hunter. From the picture, I can see that the black down jacket this person is wearing is actually a woman's model. Obviously, this black down jacket is the down jacket that the girl left on the van.

The murderer put on such a down jacket, thinking that he could disguise himself, but instead gave me a clue. The girl's height is 164 cm, and her body is thin, and the murderer can wear this down jacket, which means that her height will not exceed 170 cm, and her body is also thin.

And when the murderer withdrew money, his eyes and forehead were exposed, which are very obvious facial features. In the eyes of the criminal investigator, the outline of his facial features can be quickly deduced. As long as the portrait is more than 70% similar, the murderer is doomed.

According to the clues given by the surveillance screen, the criminal investigator quickly drew the facial outline of the murderer.

And the criminal investigator is very sure that the similarity between this painting and the murderer's facial features is definitely more than 80%.

Once you have a portrait of the murderer, you can start the arrest of the murderer.

To arrest, of course, the first task is to find this person.

Lao Lu posted the portrait of the murderer to the police's internal investigation network, but he didn't expect that only two hours later, the police at the Longbao Police Station reported that they had seen the murderer.

It turns out that the person in the portrait is named Yu Daojiu, a ruffian on the Dragon Treasure Field, although he has never committed any major crimes, but he always likes to pick quarrels and provoke troubles and provoke conflicts between neighbors. And he likes to drink, and when he drinks, he fights with others, and he has been to the police station many times because of civil disputes, and he is an uneasy person. This man doesn't have a serious job, but judging from his family background, it's not too bad. In particular, there are two Tibetan mastiffs in the house, which are not only fierce but also expensive, and I don't know how this person obtained them.

Although there is a portrait, and the portrait is very similar to Yu Daojiu, the police still can't arrest him, because there is no real evidence. It is also forbidden to attack rashly, lest it alarm the rest of the criminal gang and make them die. It will be very difficult to arrest these people again.

Therefore, Lao Lu dispatched investigators to control Yu Daojiu, waiting for an opportunity to obtain his DNA and compare it with the DNA found at the crime scene to establish evidence.

It is actually very simple to obtain his DNA, such as obtaining the drink bottle he has drunk, or obtaining the cigarette butts he has smoked, used napkins, etc., and his DNA data can be obtained smoothly.
