I don't want to solve the case when I'm a little policeman.

In a blink of an eye, the time has come to New Year's Eve.

During these four or five days, the task force found nothing and investigated nothing. They investigated all psychology students in Changming and also investigated all public officials involved in psychology.

But still no trace of the suspect was found.

In the past few days, the task force has mobilized thousands of police officers to inspect all possible suicide places in Changming, and found no signs of people wanting to commit suicide in groups.

However, it cannot be said that there was no gain at all, because we still cooperated with the firefighters and saved two people who wanted to commit suicide.

In such a big city, if someone wants to commit suicide, it is difficult for the police to detect it, and there are some places in Changming that are inherently fantasy. In addition to the Yangtze River Bridge, there are also places like Yanziji, the former number one suicide spot.

Why I say "before" is because before the bridge was built, this was the place with the most suicides in Changming. Until the great educator Tao Xingzhi wrote two plaques, there were far fewer people committing suicide here.

Tonight is New Year's Eve, and Wan Haihong specially asked two special police officers and two people from the local police station to guard Yanziji to prevent anyone from committing suicide.

Apart from here, the most stringent precautions are of course the bridges in Changming. As for the Yangtze River Bridge, the first bridge, it is naturally the top priority. Wan Haihong posted 20 people here.

There were people squatting from the beginning to the end of the bridge. When they encountered a group of people, the police on duty had to follow them closely.

The same is almost true for several other bridges. In addition to the Yangtze River, other major rivers, such as the Qinhuai River, are also key defense areas because there is the Jinling Lantern Festival here, which can be said to be crowded with tourists.

In addition to dispatching the police, Wan Haihong also asked local street and community personnel to assist.

On this day, all police forces in Changming must participate in the surveillance, including police officers who are on the Spring Festival holiday.

Various departments of the provincial government have also deployed personnel to participate in the deployment and control.

Now in Changming, the various tourist areas and streets cannot be said to be one post every ten steps, but they are almost the same.

Wan Haihong was busy until [-] noon before he deployed all the police forces. In the past few days, he had been studying the plan, the people behind the scenes, and these suicides. He rarely rested.

But now, he was not in the mood to rest. He took a sip of strong tea and asked Chief Yang worriedly, "Old Yang, are you considered impregnable now?"

During the Changming Spring Festival, a large police force was already involved in the city-wide control operation. This time, it was just stricter and more extensive with more people involved.

Chief Yang also looked unshaven and had not slept for three days. "Let's do everything we can to obey fate. We have all done what we should do. We can't impose a curfew today, right?"

Curfew, this is not the society of the past. Wan Haihong rubbed his face vigorously and touched a hand of oil. "Why are Xu Zheng and the others coming back? I will sleep for a while and wait for them to come back and wake me up."

Chief Yang nodded, "Leaders from the government, provincial departments, and municipal bureaus will come over soon. I will take them to the large conference hall over there."

Wan Haihong raised his hand, went to his office, closed the door, set the alarm, and prepared to take a nap.

At this time, Xu Zheng, Peng Yue and Li Wanwan were on their way back to Changming. They were one of the suicide victims who went yesterday, the home of the author who wrote the online article, located in the suburbs of the capital of Gan Province.

Before he came, the task force invited many experts in criminal psychology to discuss and conduct research, but they still found no useful clues or methods.

There was no progress in the case for several days, so he wanted to come to the suicide's home to have a look.

The more Xu Zheng got to know this online writer, the more he admired him. Judging from his age, he was only 22 years old. He had just graduated from college for one year and his current deposit was as high as 40.

He had no car or house, and rented a one-bedroom, one-living house. According to his family and friends, he was delivering food and barely making enough money to eat and spend money. In fact, he had already started writing when he was a sophomore in college. Internet articles.

He once wrote a book with more than 300 million words, which took a year and a half, 18 months, and the average monthly manuscript fee was more than [-] yuan.

It's just that after finishing this book, the results of several books he wrote successively were not very good, but this badness is also relative, and he still earns tens of thousands of yuan every month.

In the rental house, you can see that his life is irregular, but the quality of life is still good. His computer and mobile phone are high-end products, and his meals are packaged at a nearby restaurant, priced at 30 yuan per meal.

Not to mention smoking, 650 a piece.

After opening his computer, I found that his average coding time per day was no more than two hours. In other words, he worked less than two hours a day to finish writing updated web articles.

The rest of the time, he is either playing games or watching movies, live broadcasts, watching beauties, and having sex.
This kind of single life is definitely the envy of a large number of people in society.

Including Xu Zheng, if there was no system, he might be transferred to the criminal police team, but in terms of salary, he would not be able to save 40 in ten years, let alone smoke such good cigarettes.

Even Peng Yue has the urge to write online novels on the spot. It is so profitable. The key is that it only takes two or three hours a day.

It's just that Xu Zheng spent a day here searching, asking the deceased's relatives and friends, and even used the deceased's QQ account to contact his editor and friends in the author group, but there was no useful clue.

Until they left, Xu Zheng and the others found nothing here.

However, in order to get to know the author better, Xu Zheng took his random notes, which recorded some general information about the characters in his book, as well as some funny or meaningful passages he saw.

It's a pretty thick notebook. The author has been writing books for three years and has basically used more than half of it.

In addition to handwritten notebooks, the author also recorded something on a writer's assistant and on his mobile phone.

After a busy day, Xu Zheng and the others checked everything in the evening, and missed the last high-speed train. There was no other way, so the three of them had to stay one night near the train station.

At five o'clock in the morning the next day, I took the high-speed train and rushed to Hui Province. I went to the home of another suicide victim. This deceased was a 26-year-old female who worked as an Internet dubbing agent.

In addition to dubbing, she is also the anchor of the Two-dimensional channel on the Tuya live broadcast platform. She is the kind of female anchor whose live broadcast voice is dedicated to lulling people to sleep.

Xu Zheng searched her place all morning and found no useful clues.

This female anchor also has several handwritten notebooks, recording her methods of learning dubbing and her feelings about herself, as well as some interesting stories, sad love affairs, and things that usually make her happy or unhappy.

Maybe the woman is delicate and a bit literary. She has been doing dubbing and live broadcasting for so many years, but she has recorded four or five notebooks.

Xu Zheng also took away these notes and looked through them when he was about to go back.

It was already three o'clock in the afternoon when the three of them arrived at the Changming Municipal Bureau. Wan Haihong had just woken up. At the same time, other teams that went to other places to investigate the situation of the deceased also rushed back.

In the conference room, everyone in the task force was sitting together again. There were only 9 hours until [-] o'clock in the morning on New Year's Eve.

But the case made no progress at all.

No matter how calm Wan Haihong was, blood bubbles appeared at the corners of his mouth due to the anger, which showed how much pressure he was under. "Tell me, did you find anything when you went to the deceased's house to investigate this time?"

Huo Weian from the first team and Lang Shaobai from the second team both shook their heads, as did Xu Zheng.

On the way back, everyone had already exchanged news. If there were any useful clues, the conference room would definitely not be lifeless.Everyone was a little discouraged, but they locked their eyes on Xu Zheng, including Wan Haihong, because this case was the one for which he had seen zero clues in so many years.

Maybe there are clues in this case, but the police need time. But now, what is missing is time.

Xu Zheng also had a headache, "Don't look at me. It's useless to look at me. There are too few clues now. Instead of counting on me, you might as well count on the technical detectives to see if they can find out the deceased and the person behind the scenes." contact information."

Li Wanwan followed Xu Zheng out this time. During her free time on the way, she listened to him talk about a lot of his experience in handling cases. At this time, she was probably the only one in the whole conference room who was enthusiastic and full of unwillingness to admit defeat.

"Senior brother, you brought back many notebooks from the deceased's house. You said you would study more the notes recorded by the deceased during his lifetime, and you also said you would work on the handwriting of the deceased.

There are times when the handwriting is sloppy, indicating that the author is in a bad mood, and there are times when the handwriting is neat, indicating that the author is in a happy mood.

But I see that the latest handwriting of these two deceased people was that of a neat and unhurried handwriting. Does this mean that when they wrote this paragraph, they had no thoughts of suicide at all. "

Xu Zheng took out the notebook he brought back from the deceased's home. At the same time, Huo Weian took out an account book, and Lang Shaobai spread his hands, "The deceased I went to check also had a notebook to record his daily work.

But he carried it with him. After the body was recovered the day before yesterday, the notebook had been soaked in water and most of the writing was no longer legible. "

Everyone checked these notes, but after half an hour there was still no clue.

Just when everyone was about to change their mind, Li Wanwan next to Xu Zheng still didn't give up. She actually lowered her head and flipped through the notebook page by page, especially some notebooks with signs of tearing out a page.

She used the thumb of her index finger to carefully slide over the next page of the torn paper to feel whether, in addition to the writing that had been left on the paper, there were any marks left by the torn page.

Xu Zheng's eyes lit up, and he suddenly thought of excluding all kinds of chat software and all ways of communicating online.

Then in daily life, remote communication can also be carried out through the original method of sending letters.

However, with this method, in today's society, apart from writing letters of complaint and invitation letters sent to individuals by relevant government units, few people communicate in private through letters.

But few does not mean none. Xu Zheng himself was not sure. He pointed at Li Wanwan, who had his head lowered, and asked Wan Haihong: "Team Wan, can you still send letters between private persons now?"

Wan Haihong and everyone in the conference room looked at Li Wanwan's actions and Xu Zheng's reminder, and instantly thought of writing letters. Yes, everyone's previous thoughts were to investigate various communication methods on the Internet. .

No one has thought about this primitive way of sending letters, and even subconsciously, this method has long been eliminated.

There was a trace of eagerness on Wan Haihong's face. He walked to Li Wanwan and saw that she was holding a piece of paper on her notebook and looking at the light. He asked, "What about Wanwan? There are traces of writing on the paper." ?"

Li Wanwan looked at it for a while and found something useful, but she couldn't guarantee it because there was a page missing. Even if there was another handwriting on the lower one, it might have been left behind by the writing on the upper one.

Of course, it's also possible that it was left over from the torn page.

Two possibilities, "Team Wan, through the light on this piece of paper, there are indeed traces of the handwriting on the paper, but it is not the content of the letter written by the deceased before his death. It needs to be identified by colleagues in the technical investigation."

When Wan Haihong and others heard this, they became excited. He even took the notebook and looked at the contents of the previous and next pages.

I found that after removing the torn piece of paper, the content was coherent.

This shows that the content written on the torn piece of paper is definitely not his daily notes.

He immediately arranged, "Meiyue, please quickly check on the deceased. Did Cai Likun, the one who wrote the online article, ever go to the post office to send a letter before he died?"

At the same time, he asked Li Wanwan to send all these notebooks to the technical detective for testing.

They also arranged for Huo Weian and others to investigate all the express delivery records of the four deceased people within six months of their deaths, including the receipt of express delivery and the return of express delivery after the goods arrived.

Others may not know much about the current way of sending letters in China. He is so old and knows this industry well. Generally speaking, express delivery is faster than sending letters, and it usually takes two to three days to arrive.

Sending a letter takes three to five days.

Xu Zheng listened to his arrangement and asked quickly, "Team Wan, do you suspect that these deceased people did not send letters by mail, but by express delivery?"

Wan Haihong nodded, "Well, after all, express delivery is faster and more convenient. Even if the deceased contacted the person behind it, he might have just written the letter and returned it the same way when he picked up the express delivery."

Before the two of them could continue their discussion, Ji Meiyue had already found out that the four suicide victims had never sent a letter before.

Huo Weian and the others found out that all four of the suicides had returned goods before their death, and more than once. Especially the deceased who was a second-hand dealer in an online store had more return records.

Internet writer Cai Likun has returned goods more than 20 times in the past six months, and he has purchased goods online and on various shopping platforms more than [-] times in the past six months.

It can be said that it is used for food, drink and diarrhea. If he can buy it online, he will not go out to the supermarket. He can no longer stay at home.

Detachment Wan then ordered Huo Weian and the others, "Please investigate the return records of the other three people after the goods arrived, and see if the time of return and the person to whom the return was made are the same person?"

Huo Weian and several others quickly started investigating. Now the task force has backup information on the mobile phones and computers of the deceased to find out which platform they purchased what and which express delivery they used.

It's a very relaxing thing.

Everyone crowded behind them and watched them operate without daring to breathe. Only Wan Haihong finally breathed a sigh of relief, sat in front and took out a bottle of mineral water and took a sip.

When he saw Xu Zheng, he didn't follow him to join in the fun, and asked curiously: "Why, are you sure that our investigation is in the right direction this time?"

Xu Zheng found a piece of bread, took a few bites, and drank some water. "That's what I thought. After all, if you tore a few pieces of paper from the notebook for no reason, you must not use it to wipe your butt in the toilet, right?"

Wan Haihong was stunned and laughed, "You did a good job this time. After working hard for so many days, we didn't expect that the clues were all around us, but we all ignored this."

The clue is indeed there, but it is difficult to find. The task force has previously investigated the online shopping records of these suicides and found that the things they purchased were not suspicious.

For example, one of Cai Likun's return records is for the daily necessities he purchased, a men's razor. The platform showed that he returned the goods after the goods arrived.

This is considered a normal thing in the eyes of the task force, because there is nothing wrong with the goods, recipients, and addresses. Who would suspect that Cai Likun's return would be mixed with private goods?
Xu Zheng was thankful, "Thanks to Li Wanwan this time, if she hadn't been careful and wanted to check the torn page, I probably wouldn't have discovered this clue."

Wan Haihong said: "This is the result of one link after another. If you hadn't brought back these notebooks, and if you hadn't said that the writing in these notebooks might be clues, Wanwan would not have thought of this.

If she hadn't thought of this, you wouldn't have reminded me and then found out about the express return.

In the past, we often said that a three-dimensional analysis is required for an investigation point in criminal investigation. If we could compare these return records before, we might have discovered clues already. "

While the two were talking, Huo Weian shouted excitedly: "Wan detachment, Xiaozheng, we found a person with a mobile phone number of 189 from Magic City. He currently lives in Huangpu District of Magic City."
