Zhang Yajing has always been a suspect in this case, and now that she has turned herself in, it has led to another story.

It seems that someone is observing Zhang Yajing all the time, and has sent her a forty-seven-minute "Black Sunday", and tried to induce her to commit suicide.

But Zhang Yajing is a special case, "Black Sunday" did not make her commit suicide, but made her think about it and move towards a new life.

In the following days, the other party has been monitoring Zhang Yajing's life, and after discovering that Zhang Yajing was immune to "Black Sunday", he began to induce her to use "Black Sunday" to make others commit suicide.

Moreover, every time a person dies, the other party will make a three-minute adaptation of the song.

What was the murderer's purpose in doing this?

Speaking of this case, what law did Zhang Yajing violate in this case?

If Qiao Jiaxi wanted to untact Xia Lingyao because he had a ghost in his heart and suffered the consequences of his own evil, he drank beer mixed with potion instead, hallucinated, and committed suicide when he saw the female employee who had been indirectly killed by him.

And because the waiter didn't find out in time, when he committed suicide, it was still unknown whether "Black Sunday" was playing in the room.

There is no way to convict Zhang Yajing in this case, and the specific situation will be judged according to her subjective motives.

Similarly, the case of Ning Xiaobai's suicide is also very vague, when Ning Xiaobai committed suicide, did Zhang Yajing find out, or did she find out and did not rescue?

If she had found out that Ning Xiaobai had committed suicide at that time and did not stop and rescue her, then she would have been suspected of intentional homicide.

Because legally, there is an obligation to salvage.

If the suicide and the witness are not related, the witness is not legally responsible. For example, someone jumps off a building, and you are just a passerby, or an onlooker.

If there is a relationship between the witness and the suicide and therefore an obligation to help, the witness may be suspected of intentional homicide.

There are two main types of obligations to help, one is the status relationship, for example: between husband and wife, father and son, teacher to student, police to all citizens.

The other is the obligation to take precedence, for example: the neighbor's child has nothing to do with you, but you take him to the river to play, you have a duty to care, in case you fall into the water, you have the obligation to save, and if you don't save and drown, it is intentional homicide.

Therefore, what laws Zhang Yajing violated in these two suicide cases will have to be handed over to the people's court for sentencing when the case is concluded.

But what we have to do now is to find this mysterious person who keeps posting to Zhang Yajing.

This mysterious person began to induce Zhang Yajing to commit suicide, and now it has become instigating Zhang Yajing to kill people.

The Internet is not a place outside the law, and we already have very advanced technical detection methods.

This task was still given to Xiao Xuan, and he was asked to find a way to find out the IP address of the person who replied to the post.

This matter is definitely not difficult for our great hacker Xiao Xuan, he quickly locked the other party's IP address, which is not in Ningzhou City, but in Qingfeng City.

Qingfeng City has an acquaintance from our serious crime team, and if it is necessary to handle the case across places this time, Su Yumei and Captain Su will assist.

It didn't take long for Xiao Xuan to accurately find out the user of this IP address, named Tang Jingqi.

"Tang Jingqi, female, twenty-seven years old, only appeared in Qingfeng City recently, and has been active in the south for a long time before, and has no fixed living address."

In the office of the Serious Crime Team, we began to investigate this mysterious person named Tang Jingqi.

To investigate a suspect, the first thing we need to do is to search for the internal system network of the Public Security Bureau to see if the person has a criminal record.

Immediately afterwards, we found Tang Jingqi's name in the murder case twenty years ago.

Tang Jingqi was only seven years old that year.

We immediately retrieved the file from 20 years ago, and the case has been solved, and it is a case of "self-production and self-sale".

That is, after the murderer kills someone, he commits suicide.

The dossier contains detailed information about the case and the investigation process of the case.

The cause of this case is that when Tang Jingqi was five years old, her parents divorced, and her mother took her to remarry to a family surnamed Liu.

The man, Liu, is widowed and has a six-year-old son.

In this way, a family of four was formed.

In the beginning, the family was happy and there was no estrangement. But the good times didn't last long, and the male protagonist Liu began to dislike this Tang Jingqi, who had no blood relationship with him, favored his son everywhere, and often reprimanded and beat Tang Jingqi.

Liu's son wanted to play the piano, so Liu spent a lot of money to buy a piano, but his son had no musical talent at all, so he stopped playing for a few days.

But Tang Jingqi is very talented in music, he can understand piano scores at a young age, and he is self-taught.

In this way, Liu had a very deformed psychological imbalance, and Tang Jingqi was strictly forbidden to touch the piano, even if the piano was covered with dust, she would never be allowed to touch it.

Tang Jingqi only secretly played the piano for a while with the help of his mother when Liu went out with his son.

One day, Tang Jingqi secretly played the piano was discovered by Liu and beat Tang Jingqi.

Later, Tang Jingqi's mother came out to protect her, but she was also humiliated and beaten by Liu.

After another half a year of such a life, Tang Jingqi's mother couldn't bear it anymore and decided to kill Liu's father and son.

And the whole process of killing was witnessed by Tang Jingqi, a seven-year-old girl.

Tang Jingqi did not feel panicked, but was expressionless throughout the whole process, silently watching everything.

After Liu's father and son fell in a pool of blood, his mother, who was covered in blood, dropped the fruit knife and walked in front of Tang Jingqi.

With tears in her eyes and a smile on her face, she led Tang Jingqi to the piano and asked her to play another song for her mother.

At a young age, Tang Jingqi had many things that she couldn't understand, but she still climbed into a high chair and played the piano for her mother.

After playing the song, my mother also fell in a pool of blood and killed herself......

Later, the police intervened to investigate the incident, and Tang Jingqi was sent to an orphanage to continue living.

But Tang Jingqi suffered from traumatic amnesia.

Traumatic amnesia is a type of psychogenic amnesia and is a type of neuropsychological disorder.

Most patients experience major physical trauma or severe mental shock, such as car accidents, surgery, death of relatives and friends, etc., resulting in partial selective amnesia or temporary amnesia, which generally occurs suddenly, and may recover after a period of time.

In this way, Tang Jingqi lived in the orphanage for eleven years, and after she was eighteen years old, she left the orphanage to live.

As for Tang Jingqi's life after that, our police have not found any clues so far.
