At 08:30 the next morning, Luo Qintian squeezed his slightly heavy eyelids, got up from the computer and stretched.

The forensic doctor had already completed the autopsy. The deadly wound was on the back of the head, and he died from a blunt object blow.

According to the self-report provided by Yang Hao, they found the murder weapon—a hammer—under another concrete place.

Comparing the DNA extracted from the dormitories of Yang Hao and Yang Lei, it was confirmed that the identity of the deceased was indeed Yang Lei, and the blood of the deceased as well as the murderer's DNA and fingerprints were also extracted from the murder weapon.

Yang Hao never concealed the process of committing the crime, the method of committing the crime, the motive of committing the crime, the tools used for committing the crime, and the time of committing the crime, and he explained everything clearly.

The rest of the work is to sort out the case files, transfer the case to the procuratorate, and prosecute Yang Hao to the court.

During the period of waiting for the court's decision, Yang Hao will be temporarily detained in the detention center.

A vicious intentional homicide case took only 18 hours from reporting to solving the case.

Wang Ju patted Luo Qintian on the shoulder in satisfaction, "Not bad, Qin Tian, ​​broke the record again. Now the whole country is paying attention to this case, and immediately ask the Propaganda Section to release the information, so that the people can take a good look at our birthday. The efficiency of the city public security."

Luo Qintian said: "Ju Wang, it was my fault that I didn't let Xuan Wuji shut down the live broadcast yesterday, I'm sorry, I was reckless."

"I don't mean to blame you." Wang Ju shook his head and sighed softly, "We have handled many cases over the years, and some cases chose not to report because of fear of causing social panic, but instead encouraged criminals to be arrogant. Arrogance. Now is the information age, we should also keep pace with the times, not only to get used to law enforcement under the camera, but also to disclose information in a timely manner, and live broadcast the arrest process when necessary! This case is a good start , Bing is precious and fast, you have done a good job."

"Thank you Wang Ju." Luo Qintian responded, but he was thinking about something else.

The reason why this case can be resolved quickly this time is not him, but Xuan Wuji.

If Xuan Wuji hadn't reported the crime, the murderer would have left Shoucheng at this time, and started a new life with a new look.

No one would have thought that there would be a dead body hidden under the foundation. Perhaps they would not discover the existence of the dead until a few years later when the bean curd project was exposed, or decades later when the building was demolished.

At that time, the narrow interpersonal relationship between the murderer and the deceased made it impossible for them to determine the identity of the deceased.

The most likely result is that the police were induced by the wrong information left by Yang Hao to believe that the deceased was Yang Hao.

Without the genetic code to determine the identity, there are no clues that can be used. The suspect has undergone plastic surgery, disfigurement, or left Huaguo. All possible conjectures will make this case unsolved and finally buried in the archives.

It is a terrible thing that the dead cannot be buried in the ground, and the dead may even be charged as a suspect.

It is Xuan Wuji that allows the dead to rest in peace.

And Xuan Wuji did more than that. He disclosed the tofu dregs project, showing the sensitive incident of high-altitude parabolic to the public, so as to scare others.

Luo Qintian thought for a while, then looked at Wang Ju, "Wang Ju, there is another hero who has solved this case, I think it is necessary to award him a medal."

"It's Xuan Wuji, right?" Wang Ju laughed loudly, "I originally planned to ask the Propaganda Section to add a word of thanks at the end of the report. Since you mentioned it, I will do as you said and give him another one." Warm Crowd' medal."

"Thank you, Bureau Wang! There is one more thing I want to ask you for instructions..."

After sending Wang Bureau away, Luo Qintian went to the steamed stuffed bun shop next to the sub-bureau and ordered some steamed buns.

Twenty minutes later, when Luo Qintian returned to the case handling center of the sub-bureau, he saw a crowd of bustling people.

Song Xiaoya was busy registering materials, when she saw Luo Qintian's figure from a distance, her eyes lit up, "The boss is here."

Song Xiaoya leaned forward, "Boss, they are all victims of high-altitude parabolic objects in the No. 8 building of Kangning Community. They also saw the video after Xuan Wuji's live broadcast video went viral on the Internet yesterday. They came here today to demand that the case be reopened for investigation."

Luo Qintian scanned the hall:

There were about a dozen young people with plaster casts, young women with resentful faces, and old people with cloudy eyes, as well as their family members who accompanied them.

This group of people sat on one side of the hall, and on the other side of the hall stood a teenager with empty eyes.

Luo Qintian pointed to the boy, "Isn't he in the hospital?"

That afternoon, after Song Xiaoya brought the mother and son to the case handling center, the boy passed out, so Song Xiaoya had to find someone to take him to the hospital first.

"He asked to come over by himself, saying that he had something to report to us."

Holding a folding cane in his hand, the young man staggered to the victim, and knelt down on the ground with a crisp "plop".

"Uncles, aunts, brothers and sisters, it's all my fault. Brother Xuan Wuji went to me last night and said that you can only forgive me if I sincerely apologize. I'm sorry, I'm really sorry. It's because I'm jealous that you throw things down , I was wrong, I really know I was wrong this time."

The young man knelt on the ground, and slammed his head on the ground heavily, making a muffled "dong dong".

Song Xiaoya couldn't bear it, and wanted to go forward, but was stopped by Luo Qintian.

"My mother is really not bad, she just pampered me. The real bad person is me, I am the big bad guy who does evil. I envy my younger brother who is healthier than me, I envy my grandpa who is happier than me, and I envy my sister who is happier than me Happy. It was my jealousy that made you hurt. My brother couldn’t go to the sports school, my grandfather’s eyes got worse, and my sister couldn’t find a job. I know nothing can make up for your pain now, but I still want to sincerely say You apologize. I'm sorry, I'm really sorry! I always thought I had nothing, but I forgot, I have a mother who loves me the most in the world."

One apology after another, there is no false crying at all.

The reason why these victims were filled with righteous indignation was because they watched Xuan Wuji's live broadcast yesterday.

In the video, the boy hides in his mother's arms and looks aggrieved, isn't it exactly the same as when the boy's mother came to negotiate with them?

At that time, they thought the boy really didn't mean it, so they forgave them.

But after watching yesterday's video, they realized that the boy did it on purpose, not once or twice.

That kind of grievance crying is completely out of conditioned reflex.

Because there are too many people who need to apologize, so many that he has already learned how to use the most standard crying to win the sympathy of others.

What's even more hateful is that his mother still indulged him!

10 years old, should be the most innocent age.

A 10-year-old child should be innocent and beautiful, why did he become like that!

The child does not teach, the father too!

It's just too nasty!

They are angry that their kindness is being used, and they are angry that the teenagers in the blooming season are going astray step by step!

But now seeing the young man kowtow to admit his mistakes, everyone including Luo Qintian can see that the young man has truly repented.

Knowing mistakes can be corrected, and doing good things is great.

The purpose of their coming is not to kill them all, but to seek an explanation.

Now that the explanation is in front of them, most of the anger of the crowd has dissipated.

Since they could choose to reconcile at the beginning, it proves that they are not people who care about everything.

At the beginning, I chose to forgive because of pity, and now I can forgive them again because of the other party's sincere apology.

"The doctor said that the fracture will not leave sequelae. My child is actually very good. He has been debating whether he should take the entrance examination to the sports school or the art academy. Now it's all right. God helped him choose."

"Although my cataracts worsened, I met a very good doctor because of the concussion. He provided me with a treatment plan for cataracts. I was blessed with a blessing in disguise, and my eyes should fully recover."

"Although I didn't get the job that I had wanted for a long time, I always knew in my heart that even if I passed the interview, I would not be able to stick to it, because that job was not suitable for me."

The three families smiled and said in unison, "We have decided to forgive you and your mother."

The young woman in her twenties added another sentence, "But the premise is that you can never do bad things again, and you must educate your mother well, don't spoil you too much. What is that word called, 'drowning', spoiling It can really kill people..."

The young man laughed through his tears, raised his head and "looked" at the crowd with empty black eyes: "Thank you, you are all good people. Brother Wuji is also a good person, he is the one who woke me up."

After asking the three victims to write a letter of understanding, Song Xiaoya sent them out of the branch office one by one.

When Song Xiaoya came back, when she talked about Xuan Wuji again, she already had a look of admiration on her face.

"Boss, it's amazing. Do you think Xuan Wuji can tell fortunes? Is he a prophet? Did he guess that the three victims would come to make a second report before going to the hospital to wake up the young man?" Yes? How did he know which hospital he was in? Did you tell him?"

Luo Qintian rubbed his painful temples, "Can you stop being so noisy, my head hurts, are you a hundred thousand question marks?"

Song Xiaoya stuck out her tongue, "I'm sorry boss, I'm so excited!"

She turned on her phone and logged on to Weibo. Three out of ten topics about Xuan Wuji were among the top searches.

#玄无极直播吃土实案#

#Xuan Wuji Murder Case#

#Xuan Wuji eats human blood steamed buns#

One of the articles with the topic of #玄无极吃人血热头# was pushed to the top, and the number of readings, reposts, comments, and likes were extremely high.

Song Xiaoya looked at it, and after a while her teeth itch with anger.

This article was published by a Weibo commenter named "Arrow Piercing the Fog". The name of the article is "Xuan Wuji pretending to be a ghost, can the steamed buns with human blood still taste good?" ".

The article asserts that Xuan Wuji witnessed the burial of the corpse with his own eyes, but he didn't report to the police immediately, but used this incident to stir up heat, and he was eating human blood buns.

The article also said that the real estate where Xuan Wuji called the police to exhume the body was the property of the Xuan Group. He called the police not because of enthusiasm, but to avenge the Xuan family for driving him out of the house.

The content seems to be analyzed from a neutral point of view everywhere, but it is secretly angry at Xuan Wuji.

This article is very serious, and many people commented and supported it below.

Fortunately, Xuan Wuji did not open Weibo, otherwise Xuan Wuji's Weibo might have fallen by now.

Song Xiaoya pointed to this article, her cheeks bulging with anger, "Fart, pure fart, he is just talking nonsense without knowing anything. The suspect has already admitted that the time to dispose of the corpse is from 8 to 10 in the evening, but that day Coincidentally, Xuan Wuji has been doing late-night eating and broadcasting from 8 o'clock to 12 o'clock. That day happened to be the anniversary of his parents' death, and he seemed to be in a particularly bad mood that day. He broadcasted for four hours, crying and eating. He only left for 5 minutes during the hour, just to go to the bathroom. There is a high-rise building between Building 8 and the construction site, no matter what angle Xuan Wuji looks at from the roof of Building 8, it is impossible for him Seeing the construction site. More than 800 million spectators are witnesses of his alibi. How could he witness the burial scene with his own eyes! It's not that Xuan Wuji was exposed, how many people will be killed by an earthquake in the future! He is saving lives, not harming people!"

Song Xiaoya's eyes turned red as she spoke, and continued to scold while choking, "Why do you treat Xuan Wuji like this, he lost his parents when he was 20 years old. The Xuan family not only took away his parents' inheritance, but also kicked him out, He was forbidden to visit his parents. As the only son, he couldn’t go to burn incense on the anniversary of his parents’ death, so he could only use the live broadcast to relieve his mood. He obviously didn’t do anything bad, but he just started the live broadcast and called the police. He just saved people, why should he suffer such unreasonable infamy?! What bad things did he do to suffer these unwarranted condemnations?!"

The author has something to say: the same benefits of new articles and new articles, this chapter has 2 points and 15 characters, and a red envelope is presented!

Popular science today:

Some people may still have some doubts about DNA identification, and think that it is very simple to handle a case and compare DNA, but it is not.

At present, there are fingerprint databases and DNA databases of criminal suspects.

For example, like the cases many years ago, the suspect ran away after committing the crime, leaving fingerprint clues and DNA clues at the scene, which will be collected by the public security organs and included in the suspect database.

If the suspect does not commit crimes afterwards and the same fingerprint cannot be collected again, there will be no clues to the suspect.

There is a special department in the public security agency. Its daily job is to compare fingerprints in a huge database of suspects. The system will automatically compare, but because some fingerprints are fuzzy, manual operations are required.If a suspect has not committed a crime 20 years ago, the case seems to be an unsolved case, but once the suspect commits a crime again, his fingerprints will be left on the scene.The public security organs will compare the suspects in the two cases, so as to increase clues and be more conducive to the cracking of the case.

Now we collect fingerprints when we apply for ID cards, but you are like some suspects who know that they have broken the law and are afraid of being found, so they have been going to the labor market to do odd jobs. Fingerprints cannot be collected.

Let's talk about DNA, DNA is a very magical thing.

It is inherited by blood, and the DNA of different families is different, but the DNA within the same family is similar.

Because it involves a professional topic, let me briefly talk about it.

If the suspect left his NDA, and when compared in the DNA library, although there is no 100% similarity, but there are 70%+, this kind of person is likely to be in the same family.At this time, I went to the family in the village to investigate clues, which greatly narrowed the scope of suspects.

But at present, this method still has great difficulties.

Firstly, constructing a family DNA library is a very, very, very, very huge job. Not only does it need to count the family tree, but also collect the blood samples of the family’s males, and there are also restrictions on legalization, human rights, and so on.

Secondly, as I said before, blood inheritance, if there is an ethical aspect... then...

As for why it is a male blood sample, because males have XY chromosomes and females have XX chromosomes, please Baidu the rest.

Of course, the current DNA bank in our country is still the suspect DNA bank, and the family members of the lost children may also have joined the DNA bank, but I don’t know much about this aspect, so I can’t be sure.

So orphans like Leizi and Miaozi whose bodies were discovered many years later, it would be very difficult to find the murderer, unless Miaozi commits crimes again.

Today's technology has become more and more advanced, and there is already that kind of system software for face recognition and comparison of suspects.For example, at a large exhibition, unmanned aerial vehicles will perform face recognition on pedestrians and compare them with the database of fugitive suspects.

Now for the public security organs, the most difficult to crack is not the three-dimensional case that can leave clues, but the telecommunications fraud case, which will be discussed later.
