Don't take the bean bag as a police dog

Chapter 138
"This stick-shaped object could not be found in the carpet search at the scene. It is likely to be taken away. At present, there are no clues in the monitoring and retrieval..." Li Lei said a long paragraph in the staged case analysis, but the conclusion is only One, no useful clues have been found yet.

It's already evening, and the sky has already darkened a little. Tonight, there is a high probability that they will take turns squatting at the duty point to protect the scene while continuing to investigate and visit the surroundings.

The colleagues in the logistics of the Municipal Bureau have already brought in camp beds one after another. It seems that they will sleep in the rented duty station tonight.

Seeing this scene, Zuo Dongliang was not convinced. The more unpredictable it was, the more he felt that there might be evidence and clues that were easily overlooked.

Just now, Zuo Dongliang used the burnt plastic wrap as a source of smell. At first, everyone felt a flash of inspiration, but now it seems that this clue seems to be broken again.

Since you can't find it around, then look for it in places that people tend to overlook.

There are many ditches around this township bank. Judging from the search results of the investigators, no suspicious objects were found. These ditches are surrounded by randomly discarded garbage, scattered in the weeds, and it seems worthless to search .

However, Zuo Dongliang decided to look for clues around these ditches.

To most people, it seems careless to abandon the tools of crime near the place where the crime was committed.

This is contrary to the current case that outlines the suspect as a thoughtful and extremely cunning image, so most people think that it is somewhat impossible to find the key tools for committing crimes around.

But judging from Zuo Dongliang's superficial experience in handling cases, Bai Mi will eventually have a slip, maybe this suspect may really make such a low-level mistake.

When Zuo Dongliang decided to take Doubao out to search, it was getting darker and his vision became blurred.

However, for Doubao at this time period, this is the time of the day when the excitement and working condition are the best, and the nose is the sharpest.

Zuo Dongliang prepared three sources of smell for the bean bag, one is the plastic wrap, the other is the ashes of the burned plastic wrap, and the third is the ashes after the lead wire and the plastic wrap were burned together.

These three kinds of smelling sources act as smelling sources separately to search once, and then after permutation and combination, after mixing into three kinds of smelling sources, search again.

Of course, after thinking about it so much, if the suspect throws the stick into the water, or if the metal stick is picked up, there is no way to recover.

Whenever possible, it should be tried.

Not long after he started searching, Zuo Dongliang found that the soles of Doubao’s feet were bleeding. He looked up and saw that he had stepped on broken glass. This made Zuo Dongliang a little aggrieved. superior.

Thinking of work shoes, Zuo Dongliang remembered what Lao Yang mentioned before, no matter how complicated the environment is and when searching in mountains, police dogs should be equipped with work shoes, so as not to affect the working status due to injuries.

Now that the bean bag has started to work, I can only endure it. If there is any other bandaging, it may pass by the physical evidence.

……

The iron water pipe in front of everyone is a good crowbar.

More importantly, this is exactly the same as the iron water pipe and the stick used by the suspect in the video to connect to the ammonium nitrate bomb and then pry open the ATM machine.

After the smell of the bean bag, there were embers left after the plastic wrap was burned on the iron water pipe.

This was found in a dense grass not long after the sole of the bean bag was punctured by a piece of glass.

At that time, the source of smell provided by Zuo Dongliang to the bean bag was the embers after the plastic wrap was burned.

Later, Zuo Dongliang took this iron water pipe back to their duty station and inspected it. He also took the sample of embers from the ammonium nitrate explosion as a source of smell, and searched for Doubao. Doubao also found this water pipe.

This proves that not only the embers of the burning plastic wrap but also the embers of the ammonium nitrate explosion remained on the iron water pipe.

Based on this inference, this iron water pipe was the suspect's crime tool at that time.

There is no need for the colleagues in the technical investigation department to do further composition identification, and everyone decided to use this iron water pipe as another direction for handling the case.

Looking at it now, the suspect is really careless now. If you think about it to the extreme, you can even imagine that the suspect is a little arrogant and left such a key tool for committing crimes within a range of less than 200 meters from the scene. .

Doubao made another contribution.

However, after a short period of joy, everyone fell into silence again, because this water pipe cannot lead everyone into new progress.

Judging from the video surveillance, the suspect was wearing gloves to commit the crime, so no fingerprints would be left on it. In addition, there is no other smell or special feature on this water pipe, so it is temporarily impossible to find out more and information on the suspect's hookup.

So tonight, I must sleep at the duty point.

The duty point is a small breakfast stall closest to the bank that was temporarily expropriated. It doesn’t even have a business license.

The bureau approved the expropriation fee of 200 yuan, and the stall owner readily agreed. The stall owner said that it could cover her daily income from selling breakfast. In this way, this kind of stall business is not easy to do.

The stall owner would like everyone to rent it for a few more days, but colleagues from the criminal investigation team and Zuo Dongliang thought it would be best to move out of this duty station as soon as possible.

Zuo Dongliang, Li Lei and three colleagues from two foreign countries were squeezed into the small room of the duty station. Li Lei arranged for the other colleagues to go home. Now that they are ready for a protracted war, let them Everyone gets a break in turn.

In the small room, Doubao slept under Zuo Dongliang's camp bed.

It is a good thing to have bean bags. At the duty station that is very close to the bank where the incident happened, if anyone approaches this point, the bean bags can serve as a good warning.

Fortunately, Dou Bao had taken a shower before going on duty, so he didn't smell bad, otherwise, the colleagues in the whole room would probably have objections.

If he is on duty for a few more days in the future and needs to sleep in this base, it is estimated that Doubao will have to sleep outside the house.

At this time, a colleague snored.

Every time I live in a room with my colleagues, there is always snoring.

You can tell from the snoring sound of this snoring colleague. He is Yu Licheng who visited the surrounding villages today. He hardly had time to sit for a while today. After Li Lei announced that he could sleep, he fell asleep without saying a word. Start snoring.

It's only ten o'clock now.

Zuo Dongliang had never slept at this point before, and he was snoring, so he tossed and turned and did not fall asleep.

At this time, the mobile phone has a WeChat message notification tone.

This message was actually sent by Shen Jing.

In the chat box, Shen Jing shared a short video, and then asked: "Is it you that the policeman with the police dog in this video?"

Zuo Dongliang opened it and found that this short video was taken by a citizen with his mobile phone. Zuo Dongliang saw that it was himself and Doubao.
