Chapter 312 Monitoring

Shen Yaowei brought his new partner and called a familiar auxiliary police officer from the public security detachment. Following the route set by Jiang Yuan, they swept small hotels, homestays, farmhouses and rental houses from alley to alley.

After careful searching, there were surprisingly many places to stay near a village. In cities, staying in hotels or homestays requires quite strict registration, but in rural towns, this registration is very superficial.

Fortunately, for their own safety, and also to ensure that the house is not sold privately by the front desk, the boss always actively installs various surveillance cameras, so it is not too difficult to check people.

Shen Yaowei mainly followed the borrowed auxiliary police officer Wang Zhibing to investigate.

Unlike what ordinary people imagine, auxiliary police are already an indispensable member of current police activities. Especially in grassroots departments, the establishment of auxiliary police has long become tight. The quota of 300 people taking the exam for one auxiliary police officer seemed like a story earlier, but later it became common.

And there are many auxiliary police officers who have been working for a long time, and have been working for more than ten or twenty years. Now it seems that many people will probably retire.

And if you work in any position for a long time, you will naturally accumulate experience and knowledge. Those who are a little smarter can master many unique skills.

For example, Wang Zhibing, who was found by Shen Yaowei, knows all the rental houses and small hotels in various streets and places in the area he is responsible for.

This is also a skill. Not only is it familiar with the streets and alleys, but it also requires considerable affinity, otherwise, just updating the news of those small hotels and rental houses will make his knowledge lose its effect.

"Boss, have you seen this person?" The three people in plain clothes entered a homestay and called out the boss, which was a language output.

The output was also mainly completed by auxiliary police comrade Wang Zhibing. He knew these bosses too well. Those who followed the rules were also very disciplined, and those who did not follow the rules were also quite unruly. So he asked for surveillance video and adjusted it to the time of the incident.

If the surveillance video was too short, he would call a few waiters to ask and leave business cards for the other party. It took almost half an hour to ask a homestay.

After leaving the house, Shen Yaowei said helplessly: "Our efficiency is too slow."

"Not slow, the one just now was a bit troublesome. If there were surveillance videos, or small ledgers, or payment records, we could check these and finish in just ten minutes. This kind of homestay has few guests coming in and out all day long." Wang Zhibing is also very familiar with investigations.

Shen Yaowei frowned: "With so many homestays, small hotels, and rental houses of sub-landlords, how many days will it take to check."

"You don't want to check it all by yourself, do you?" Wang Zhibing was a little amused, but seeing Shen Yaowei's serious expression, he couldn't laugh anymore.

Shen Yaowei asked: "No." Wang Zhibing said: "Really not."

"Then let's investigate separately, three times faster, how many days can we finish the investigation?"

"Captain Shen, if the three of us are separated, what you find can't be used as evidence, because the chain of evidence is incomplete. At most, it can be used as a clue to solve the case, but such an important clue is a murder case, and the procuratorate will definitely ask carefully. At that time, don't get no credit and get scolded."

Shen Yaowei was stunned, he was not completely unreasonable: "I haven't thought about this."

"Right. In fact, investigation is the work of three people. For a normal murder case, if you want to investigate this kind of thing, you have to send five or six groups of people. If it is an important clue and the scope is large, it is appropriate to send dozens or hundreds of people."

Auxiliary police officer Wang Zhibing has not participated in many major cases. For the cases he has participated in, the scale of hundreds of people is the limit.

Of course, this is also related to the region. For example, in the best places like Beijing, Shanghai and Guangzhou, when encountering a murder case, thousands of people will be organized in minutes.

Therefore, the choice of the region for killing is also very important. In ancient times, bandits liked to live at the junction of three counties, the junction of two prefectures, and the thoroughfare of nine provinces. This is all supported by criminology. Modern society has changed. Generally speaking, the choice is safer and less difficult.

Shen Yaowei also figured it out at this time

said: "It means that the clue I am following is a line of investigation?"

"You don't know?" Wang Zhibing looked at Shen Yaowei.

Shen Yaowei said speechlessly: "I haven't followed the backlog of murder cases."

To be precise, he has never really entered the stage of solving the backlog of murder cases. In the past, once the backlog of murder cases task force really found clues, it was the rhythm of mobilizing the entire detachment. Even if Yu Wenshu is not in charge, he will take charge and pay attention.

In some cases where the backlog of murder cases is more valued, there are also cases where the deputy director or even the director takes charge.

In a task force of this level, Shen Yaowei's little connections are useless, and no one will allow him to track a clue. What if he alerts the enemy?

Alerting the enemy is not a big deal. Most of the unsolved murder cases often have only one clue. White Shirt wants to sniff it out personally, so how can Shen Yaowei have a chance?

In other words, in Jiang Yuan's unsolved case task force, one reason is that Jiang Yuan's level is too low and the resources he can mobilize are too few - Yu Wenshu bought him here for this cost-effectiveness.

Another reason is that Jiang Yuan's speed of solving cases is too fast. Before the leaders above have time to hold a meeting to assign tasks, a unsolved murder case may have been solved.

Later, Jiang Yuan solved the case much faster than the leaders were concerned about. In addition, the resources he used were always at the detachment level, so there was no need to expand.

From this perspective, Shen Yaowei has been reused unprecedentedly.

"What do you say? Shall we continue to investigate?" Shen Yaowei rarely asked the police officer who was his partner.

The partner said: "Let's go back to find Jiang Yuan now. Even if we send more people to investigate this line, can we be the commander?"

Shen Yaowei still has self-knowledge: "That's definitely not possible. No one will listen to us even if we send more people."

"That's it. If we work hard, we will have a separate clue to follow. If we don't work hard, we can go back to the office and continue to sit."

"Well, let's continue to investigate." Shen Yaowei figured it out a little.

The partner police officer was not surprised at all and said, "They are good people. They are not afraid that we will not work." Shen Yaowei said with a common hatred, "I didn't expect that the people from the county would be so cruel."

"The cruelest thing is that Jiang Yuan has extra clues and throws them to us like bones. In other special task forces with unsolved homicide cases, such bones are hard to get."

"What you said" Shen Yaowei was powerless to refute. Thinking about it carefully, it was really the truth. On the contrary, auxiliary police officer Wang Zhibing was a little curious: "I was also thinking before, what other clues does he have?"

"Captain Jiang, the image detection team has checked all the surveillance cameras on the main roads, but the deceased has not been found."

Miao Liyuan, a police officer who volunteered to check the surveillance cameras in the image detection detachment, delivered the conclusion of the clue that Jiang Yuan was most looking forward to a day later.

But there was no result.

Jiang Yuan frowned slightly: "Didn't the deceased go to the main road?"

"We have watched the surveillance from April 17 to 22, especially the surveillance on April 17. We have watched it several times, but we didn't find the deceased." Miao Liyuan was also a little disappointed.

In this case, if the deceased can be found, then his co-passenger, even if he is not the murderer, can definitely provide a lot of information.

"In this case, we can only expand the scope." Jiang Yuan pondered for a few seconds and made a decision. Miao Liyuan said, "I checked very carefully."

Jiang Yuan said firmly, "I didn't say you didn't check carefully, but the fact that the deceased was not found means that they may have taken other routes or just avoided the surveillance. Expand the search area and talk about it if you can't find it."

Tang Jia was in the office and heard the conversation between the two. He interrupted, "Why did they just avoid the surveillance and not deliberately avoid it?"

"In this case, judging from the condition of the body, I am more inclined to believe that it was an accidental death after being drunk. The deceased should have been choked to death by vomit." Jiang Yuan said, and added, "There is no reason for the deceased to be murdered."

"Isn't it enough to be raped by a prostitute?"

"The deceased is strong and shows no signs of resistance. Moreover, there is no need to kill people with fencing. If you rape a man, it is at most a crime of indecent assault, and there is no need to kill people." Jiang Yuan paused and said, "I basically agree with the conclusion of the autopsy. If it was an accidental death, the murderer would not have had to avoid surveillance when he left at the beginning."

Miao Liyuan was convinced and could only desperately stimulate his brain to think. Jiang Yuan did not urge him.

After a while, Miao Liyuan whispered: "Could it be that he rode a motorcycle and took a small road?" Jiang Yuan looked at Miao Liyuan.

Miao Liyuan said: "Local people use motorcycles a lot, and it is possible that he wore a helmet. Not many local people wear helmets, but some motorcycles do not take the main road, but take the small road, and may just pass the surveillance."

Jiang Yuan said: "It is possible, then how to check in this case?"

"Then we have to check the scene road by road, some may be found, and some may not be found."

"Okay, I will report to Captain Yu." Jiang Yuan said and took out his mobile phone.

Miao Liyuan suddenly lost confidence and hurriedly said: "This may not necessarily find anything."

"Search as much as possible. Especially a few hours after the victim left home. Don't worry about resources." Jiang Yuan said confidently.

Although the original task force spent a lot of manpower on the investigation, their investigation was mainly concentrated in the local area, the first scene was also nearby, and the time of death was also the day the victim disappeared. Naturally, they would not spend too much effort on the route and video of leaving.

Jiang Yuan still had high expectations for surveillance.

The surveillance system around Changyang City was relatively complete. If the victim or the murderer did not deliberately escape, the probability of being photographed was very high.

Even if a lot of manpower and material resources were spent in the end and the person was not found, it could prove something in reverse. Moreover, the route of Shen Yaowei and Miao Liyuan was not the only one.

The trace evidence laboratory was also doing a new round of tests at Jiang Yuan's request.
