According to Shaodong's habit, I will put things I can't figure out first and then slowly think about them.

Because of this, Shao Dong turned his attention to Cheng Feng of the criminal police team. He immediately stood up and said, "We have already learned about the staff of the security company in the past five years. Among the 92 veterans, eight of them serve in special military branches. Today, we are investigating these eight people. However, these eight people have withdrawn from the security company without exception and are now used as bodyguards for some businessmen in other places. Except for three of them who have not been contacted, the other five people have been contacted, which can rule out their suspicion of committing crimes. As for the other three, we will also try to contact them earlier, but judging from what we have learned, their chances of committing crimes are very small."

After saying that, Cheng Feng sat down again. To be honest, he had almost no useful clues every day.

A criminal policeman next to him also stood up and said, "We have conducted a survey with all the police stations in the county town today. At present, there are 396 people who have two labor and one reform in each district. Moreover, the police stations in each district have a good understanding of these personnel and have a preliminary understanding that these people do not have the obvious characteristics of the suspects in this case."

The person who said this was Zhang Qiang, who was also an old man from the criminal police team.

Before he visited the police station in the jurisdiction today, he also went with hope, but after the visit, he was completely confused. As he said, it was not that he looked down on these guys who had made a mistake and had made a mistake. They might be able to do it in secretly kidnapping and cheating. However, in cases like today, they really don’t have the ability to do this. At least, some of them deliberately hurt people and robbery. However, judging from their previous cases, they were not professional in starting a job. Judging from the operation of killing them with one knife today, they were just amateur players.

"Okay, this line cannot be ignored. These people who have been working for one labor force, especially those who have served more than ten years of prison, have no skills after they are released from prison. Moreover, in the past decade, the rapid development of society will lead to their disconnection from society. They will not be sure of what they will do. As for the differences in the methods of committing crimes, it is difficult to guarantee that they have not learned anything in prison for more than ten years."

To be honest, although the clues now point to the fact that the murderer is not an ordinary person, Shaodong has been a soldier after all. He is unwilling to believe that the people trained by the country would do such a thing. Of course, if you don’t believe it or not, if you handle a case, he will not bring personal feelings into it.

"Now everyone's work has been reported, I will talk about the discovery of the Internet monitoring department."

Shao Dong said: "Just just now, Captain Wang and I went to the Internet Supervision Department together. Director Huang of the Internet Supervision Department proposed a hypothesis with us."

The Internet monitoring department has always been an emerging department that is vigorously developed by the bureau. In this era of big data, the role of the Internet monitoring department is unquestionable. In the past, the Internet monitoring department has provided crucial clues in other cases encountered by the criminal police team. However, today, the Internet monitoring department seems to have suddenly become deserted. When everyone is not used to it, Director Huang actually put forward a hypothesis, and it can make Shao Dong say it here. Obviously, this hypothesis has fallen into Shao Dong's heart.

It is also because of this that everyone listened carefully to Shao Dong's words at this time.

"This is the thing. Because the network surveillance department did not find any valuable clues in the screening of surveillance videos, they guessed whether the suspect would still be hiding near the crime scene and did not leave."

Shaodong did not keep it a secret, but said it directly.

Of course, as soon as his theory came out, the conference room was in an uproar, because in their opinion, if they were robbers, they would definitely try their best to escape the scene at this time. How could they still stop at the crime scene? Not to mention hiding near the crime scene.

"Is this unlikely? No matter how brave these robbers are, they will not stay at the crime scene and wait for us?" The first question was Jiang Weimin.

Then, Wu Zhong also said: "I also think this is unlikely. Near the crime scene, either KTV, bar, nightclub, or various night market stalls, the suspects have nowhere to hide."

"Yes, and there are no residential houses in the several streets near the crime scene, and they are all shops or hotels. The suspects have no place to settle in this area."

Cheng Feng from the Criminal Police Team also expressed his opinions.

Shao Dong also thought about their views and continued to say: "This is not the most important thing. The most important thing is that the network surveillance department screened all surveillance videos within a radius of one kilometer a week before the incident, but found no useful clues. In other words, within a week before the incident, the suspect's vehicle did not appear.

Everyone should be very clear about what this means.”

Because of Shaodong's words, everyone was silent. There were no suspicious vehicles a week before the incident. What does this mean? This means that the suspect drove the vehicle in more than seven days before the incident and kept hiding, waiting for the action early this morning.

"If we follow the speculation given by the Internet monitoring department, then I have a question. Since they drove in before and were dormant, why didn't they start earlier? You know, there are armored cars every morning, why did they have to wait until today to start?"

Wu Zhong asked with confusion: "Is today different from any day before?"

Speaking of this, Wu Zhong was stunned for a moment, and then everyone was stunned for a moment.

Because they thought of a question at the same time, it was different, because there were 37 million in the armored truck today, which was a total of 27 million more than before!

"Does the robbers know the amount in the armored car?" Jiang Weimin asked with confusion.

Zhang Qiang nodded and said, "It is very likely that they have an in-house adviser like Xie Jun."

Just as they were discussing fiercely, Shao Dong said: "Have you ever thought about when the robbers' cars would drive into the vicinity of the crime scene?"

Everyone was stunned. What is the problem? We are not discussing this?

Seeing this, Shao Dong said: "I was thinking before, why did the robbers delay in taking action after driving the car into the crime scene in advance? What are they waiting for? Now, I figured it out, they are waiting for time!"

"Time? When?" someone asked in confusion.

At this time, Wang Gang said suddenly: "Are you saying they are waiting for the surveillance video to automatically cover the time?"

Generally speaking, the surveillance video storage time is three months, and surveillance videos over three months will be automatically overwritten by the system.

If Shaodong said this, then it has been more than three months since the robbers drove their car into the crime scene?

However, this also proves why the online monitoring department screened the surveillance video a week before the incident and found no useful clues.

Because the suspect had already driven the car into the crime scene three months ago, it was impossible for the network surveillance department to find any useful clues about the vehicle.

But if you speculate so, where will the suspect hide the vehicle in the crime? It’s not like to put it on the crime scene. If they do all this three months in advance, isn’t it a waste of time and energy? But near the crime scene, if they park in a public or paid parking lot, the surveillance video will also expose them, so no matter what, this is an unexplainable problem.

Immediately, someone raised this question.

When Shaodong first made this inference, he had already thought about this question, so he didn't hesitate and said directly: "Although I didn't think of the reason for this question, if the suspect really hid the car near the crime scene three months ago, then we just need to go to the crime scene to investigate. No matter what the truth is, there will always be an answer."

As Shao Dong said, no matter what the truth is, as long as you visit and investigate, there will always be an answer. If this answer is not yes, it is no.

Moreover, what Shaodong really cares about is not this answer. If this inference is true, it means that the suspect really entered the crime scene three months ago and hid for so long, and waited for this day. In this way, it means that these robbers had carefully planned and conspired for a long time to carry out this big robbery.

To be honest, Shaodong is not afraid of these murderers being brave, nor is he afraid of these murderers being ruthless. He is afraid that these robbers will be cautious in everything. Such murderers will only hide deeper and make their case difficult to solve invisibly expand.

At this time, all the participants were silent and they realized the problem. Moreover, if the suspect was still hiding near the crime scene as the Internet surveillance department speculated, it would be quite difficult for them to confirm that a car had indeed been parked near the crime scene within the previous three months.
