After a brief communication with Zhang Zhengang, the two went to the conference room together.

At this time, five hours had passed since the morning cash truck robbery.

In the public security system, generally speaking, the golden time to solve a case is seventy-two hours, although it seems that there is still plenty of time now, but for those who have worked as criminal policemen, every minute and every second is extremely worth cherishing.

After sitting in the conference room, Zhang Zhengang first introduced Shao Dong to everyone.

Although everyone has never seen Shao Dong, they have already heard of it, because this young man who has repeatedly solved strange cases in the city bureau is more or less a celebrity in the public security system, and there are many positive rumors about him, and everyone is not unfamiliar with him.

With Zhang Zhengang pressing the formation, everyone didn't react excessively, of course, it is impossible to put an end to talking about two sentences in private.

Because Wang Gang did not come down on the kidnapping case at this time, this meeting was presided over by Section Chief Jiang of the Technical Section.

After getting Zhang Zhengang's nod, Section Chief Jiang slowly walked to the front of the curtain.

There was no nonsense, Section Chief Jiang directly put a few slides, and then slowly introduced.

"At 7:39 this morning, the 110 Reporting Center received a report that a cash truck had been robbed at the intersection of Night Market Street and Langde Street, and there were four escorts in the car, carrying two shotguns, belonging to our county's security company. All are specially trained veterans with a good social background and no criminal record or criminal record. Here is a recording of the call from the 110 alarm center. ”

After speaking, Section Chief Jiang played a recording of the phone call.

In the recording, as soon as the operator at the 110 alarm center answered the phone, a man's yelling was heard.

"We've met robbers in our cash truck!" At the same time, the sound of banging the windows came one after another, and after the man said this, there was no follow-up, and the phone was hung up.

After the recording was played, Section Chief Jiang continued: "According to our preliminary understanding, the police were called by a banknote keeper in the cash transport vehicle, named Xie Jun, who used the emergency alarm in the car to get in touch with the 110 alarm center, and the operator of the 110 alarm center also reported to his superiors as soon as the phone hung up, and our police arrived at the scene of the crime at 7:50, when the robber had disappeared without a trace. ”

Judging from Section Chief Jiang's introduction alone, the murderer who was robbed of the cash truck completed a series of actions within 11 minutes, including smashing windows, killing people, and robbing money, and then fled the scene.

It stands to reason that this is an unrealistic operation, because when Xie Jun called the police, it had already been shown that they were aware of the seriousness of the problem, and they had two shotguns in their hands, not to mention killing the gangsters on the spot, but there should be no problem with the gangsters for a while.

The most important thing is that the gangsters are using cold weapons in their hands!

Of course, there is another problem that cannot be ignored, that is, when they called the police, the gangsters smashed the car window, why didn't they resist?

"Section Chief Jiang, I have a question. The one who spoke was a middle-aged man sitting next to Zhang Zhengang, who had also been introduced before, named Cao Feng, and was the executive deputy director of the H County Public Security Bureau.

"Cao Ju, you asked. ”

Cao Feng asked directly: "According to the data given by the 110 alarm center, we have a preliminary estimate that it took 11 minutes from the time the case occurred to the time we arrived at the scene, so what I want to know is what the four banknote transporters were doing during these 11 minutes? Except for Xie Jun, who called the police, what about the other three? We obviously heard the sound of hammers smashing the car windows in the phone recording just now, I think, the shotguns they are holding are not decorations, right?"

For Cao Feng's question, everyone fell into deep thought, to be honest, they had thought about this question just now, but they also didn't get an answer.

Since there is a problem, Zhang Zhengang said: "Okay, let's discuss the question raised by Director Cao." ”

Although Zhang Zhengang has not made much achievements in solving cases, he is professional in terms of presiding over a meeting.

With Zhang Zhengang's opening, there was a lot of discussion in the conference room for a while.

Shao Dong listened carefully to everyone's discussion, but did not discuss anything valuable.

Just when the discussion reached an impasse, Zhang Zhengang glanced at Shao Dong, who was sitting at the bottom of his hand, and saw that he didn't say a word for a long time, so he took the initiative to ask: "Director Shao, what do you think about this?"

Seeing Zhang Zhengang call his name, Shao Dong was also stunned for a moment, and then said: "I can't talk about opinions, everyone should exchange ideas." ”

To tell the truth, he didn't say a word before, and listened carefully to other people's discussions, and his main purpose was not to hide his clumsiness, firstly, because he was new to the university and did not know these peers, and secondly, he also wanted to see what level these colleagues in the H County Public Security System were.

However, now that Zhang Zhengang has named himself, Shao Dong has to say a few words.

"As for the question that Cao Ju mentioned just now, in fact, we only need to care about two points: first, what were his three colleagues doing when Xie Jun called the police? Second, how did the robbers react when they smashed the windows?"

After speaking, seeing that everyone was looking at him, Shao Dong said again: "Then let me talk about the first point first, from the recording just now, it is not difficult for us to find that the robbers had already begun to act at that time, smashing windows and breaking doors, these behaviors have already posed a threat to our money carriers, and they have every reason to suspect that these people are plotting against each other, so resistance is certain, since they are resisting, this involves the second question, their reaction?"

Logically speaking, the first thing any money carrier encounters when this kind of thing happens is to take up arms to resist, but have you noticed that when Xie Jun called the police, we heard nothing but Xie Jun's voice and the sound of smashing windows?"

"Nothing, huh?"

After Shao Dong finished speaking, someone immediately said it.

After speaking, some people echoed a few words together.

"Yes, there is no other sound. After hearing this, Shao Dong said with a smile.

From the very beginning when he heard the recording, he wondered about the question.

Before the others could react, Shao Dong said, "Don't you think it's strange? Why did we only hear Xie Jun's voice? Shouldn't there have been four people on the cash truck at that time? And the other three?"

"Could it be that a few other people didn't speak because they were afraid that there would be too many people to talk and they couldn't speak clearly?"

Immediately, someone said what they thought.

But Shao Dong still smiled and said: "Even if this statement is true, let's think about the environment at that time, the gangsters were already smashing the windows, don't they resist? If they resist, why is there no movement at all? Isn't it strange?"

When Shao Dong finished speaking, most people looked like they suddenly realized, indeed, but if there was resistance, how could there be no sound?

At this moment, Wu Wei, who came down with Shao Dong, stood up and said, "Everyone listen to me. ”

When everyone shifted their attention from Shao Dong to Wu Wei again, Wu Wei said: "I am a forensic doctor, so let's talk about some clues from the perspective of forensic medicine.

First, according to our preliminary investigation, there was no sign of strong resistance on the cash truck, in other words, all the cash carriers died in their seats.

Second, all the deceased were killed with a single knife, and whether it was the trace or the depth of the wound, it was different, judging from the wounds of the deceased, there were four different types of sharp knives, and from this point it can be judged that the murderers should be four. ”

When Wu Wei finished speaking, the murderer was a few people, and everyone didn't care, and the one thing everyone was most concerned about was that the victims didn't resist!

"Could it be that the robbers are acquaintances?" someone speculated.

Another person said: "It's not right, everyone's life circle is different, it is impossible for the gangsters to know even four people, right? If you only know one or two of them, the rest of the people will not relax their vigilance, and on the way to transport money, the walking route and time of the money carrier are all required." ”

After saying that, this person also touched his head, if the murderer was not an acquaintance, how did he subdue the four people in an instant?

"What if the murderer is also a money carrier or used to be a money carrier?"

This statement immediately resonated with everyone.

However, at this time, Yu Shuibin of the technical department stood up, he was the same as Wu Wei, he was the deputy chief of the technical department, Wu Wei was a forensic doctor, but he was an expert in trace identification.

"If the gangsters and the banknotes carriers really know each other, then the scratches we found in front of the banknotes trucks will also have an explanation, but there is a question that I am curious about, if the gangsters and the banknotes carriers know, why do they smash the windows? I don't mean that they are not dedicated to their work, but everyone also knows that the current society is like this, since it has stopped, then it is normal to open the door and talk about smoking, if this is what happened, then they intercept the banknote truck, the purpose is nothing more than to create an accident, and then wait for them to open the door to do it.

But if this is the case, then wouldn't it seem that their behavior of smashing the windows of the car was superfluous? Moreover, when our technical department was investigating, they also found traces of prying doors, how can we explain this?"

After listening to Yu Shuibin's analysis, Shao Dong also frowned, not to mention, Yu Shuibin is really the head of the analysis, but no matter how he analyzes it, he can see that this cash truck robbery is confusing.
