Chen Shi's death was too sudden, and many suspicious points need to be investigated by the police one by one.

With the arrival of the provincial department, the progress of the investigation is progressing rapidly.

It didn't take long to find out Chen Shi's information and his motive for committing the crime.

Chen Shi, male, 23 years old, from Xiacheng District, Baiyin City, studied at OUHK and graduated with the first grade, and then applied to join the Baiyin City Criminal Investigation Squadron as a probationary police officer.

Chen Shi is a single-parent family and grew up with his father.

When he was very young, his mother couldn't stand the fact that the other party was an assistant policeman, so she was away from home every day, and ran away with a photographer.

His father died twelve years ago.

According to archival records, Chen Shi's father, Chen Hong, committed suicide at home and left a suicide note before he died.

Chen Hong worked as an assistant police officer for seven or eight years, but he was never able to become a regular, and before committing suicide, he failed the thirteenth exam.

During the years of being an assistant policeman, there were many things, heavy tasks, and great pressure, not to mention the pressure, and I offended many people.

In addition, because he is an assistant policeman, once something bad happens, Chen Hong will stand up and take the blame.

And this also makes it difficult for Chen Hong to change jobs.

The work was not going well, his career was blocked, and his family was still in a mess, and under all kinds of pressure, Chen Hongcai chose to commit suicide.

However, after an in-depth investigation, the police were surprised to find that there was a big problem with Chen Hong's death.

First of all, Chen Hong passed the thirteenth exam, but it is still in the last review stage, as long as he passes, Chen Hong can become a regular.

But because of internal regulations, before the official results come out, the people participating in the assessment do not know, and Chen Hong naturally does not know.

What's even more strange is that the first person to find out that Chen Hong committed suicide happened to be a colleague of the person who informed him of the results of the exam.

But the suicide note left by Chen Hong said that he failed the exam again, which is very contradictory.

Secondly, according to the memories of Chen Hong's colleagues and friends, Chen Hong behaved normally before committing suicide.

While having dinner and drinking with friends, he once said that he was ready to quit his job.

Listening to the meaning of his words, I must have found a new job.

But now that I've found a new job, there's no way I'm going to commit suicide.

After the incident, the police also found out that Chen Hong found a new job, which was a courier.

According to the recollection of the boss of the express company, half a month before Chen Hong committed suicide, he interviewed Chen Hong, passed the interview, and was given a high salary.

It's just that Chen Hong is an assistant police officer, and he needs to go through the process if he wants to resign, and this process will take about a month.

The police found the resignation report in the drawer where Chen Hong worked, but did not hand it in.

As for why it didn't, it is unknown, but it should be related to the 628 case.

But in any case, since Chen Hong has decided to resign and found a new job, it is even more unlikely that he will commit suicide.

In addition, Chen Hong was the first person to discover the scene of Y's crime.

It's just that Chen Hong is an assistant police officer and has no official establishment, plus he committed suicide, so the credit that originally belonged to him was not recorded.

The last suspicion is that Chen Hong's home is too clean, apparently it has been cleaned, and the police did not find any useful clues when they investigated.

So, according to the content of the suicide note, coupled with the fact that all the attention of the police at that time was on the 628 case, Chen Hong's death was finally characterized as a suicide.

But now it seems that Chen Hong is obviously not committing suicide, but murder.

The person who killed him was none other than the real culprit Y in the 628 case!

It's just that a case and the deceased are not qualified, and naturally no one cares.

But all this was seen by the young Chen Shi.

After Chen Hong's death, Chen Shi became an orphan and was sent to live in an orphanage.

The orphanage where Chen Shi is located happens to be opened by Han Meimei.

During this period, Chen Shi met Song Lang, and the two became friends.

It's a pity that it didn't take long for Han Meimei to be killed, the orphanage was also disbanded, and Chen Shi and Song Lang went to different orphanages.

After Chen Shi went to the new orphanage, he performed very well and studied very hard, and in the end, he was admitted to the OUHK as he wished.

Chen Shi chose to take the police academy, mainly because of his father's influence.

But the most important thing is that he wants to find out the truth of the 628 case and catch Y!

After being admitted to the police academy, Chen Shi met Song Lang again, and the two became brothers.

However, since three years ago, Y's last crime led to the death of the captain of the criminal investigation squadron, and since then, Y has stopped committing crimes, which makes the two who want to investigate the 628 case confused.

As for why Chen Shi killed Chen Xuefeng and Shen Jiayi, the reason is actually very simple.

On the one hand, it is because of his good friend Song Lang, and on the other hand, the girl he likes is also a victim of Chen Xuefeng's clutches.

It's just that the girl didn't choose to call the police afterwards, but left Baiyin City and went to live in other cities.

In addition to this, there is a hidden reason.

Chen Shi's mother ran away with a photographer, so Chen Shi was naturally hostile to this kind of person.

It's just that how Chen Shi and Song Lang embarked on the road of crime, the police have not found out for a long time.

In the end, it can only be attributed to the fact that Chen Shi gradually went astray because of the death of his father Chen Hong and the influence of Song Lang.

It is worth mentioning that after Chen Shi's death, the police searched his home and then found a lot of evidence.

For example, tracking and taking photos of Chen Xuefeng, Chen Xuefeng's action route, and the girl who is suspected of being hoked by Chen Xuefeng, etc.

The most important thing is that they found the key to Xu Mo's house in Chen Shi's house, as well as the night of the 404 crime, Song Lang filmed a complete video of the scene.

The video clearly recorded how Chen Shi disguised himself as Xu Mo and killed Chen Xuefeng and the others.

With these key evidence, it not only proved that Chen Shi was the murderer of the 404 case, but also completely cleared Xu Mo's suspicion.

After several days of investigation, except for why Chen Shi and Song Lang went astray and chose to kill, why Song Lang lost control of his emotions, and why they framed Xu Mo before they died, other doubts were basically clarified.

After clarifying these, the 404 case was officially closed, and part of the facts of the case were made public.

Xu Mo was finally able to leave the police station.

……

……

"Is Chen Shi really the real murderer of the 404 case?"

Fang Mo personally drove Xu Mo home, and when he was about to arrive at the place, Fang Mo couldn't help but ask.

Xu Mo, who was sitting in the co-pilot, was looking curiously at everything outside the window.

Hearing Fang Mo's words, Xu Mo turned his head to look at Fang Mo and said with a smile: "Don't you all find out and close the case, why do you still ask me?" ”

"Crunch!"

Fang Mo braked and pulled over the car.

Then he turned his head, looked at Xu Mo with a serious face, and asked, "Xu Mo, tell me the truth, was it Chen Shi who attacked you that night?" ”

The two looked at each other for a moment, and finally Xu Mo shifted his gaze.

"Yes or no, is there a difference?"

"Of course."

"What's the difference?"

"The difference is ......"
