Police Detective

It was almost eight o'clock in the evening. It was already dark at this time of year. No one who saw the police was interested in watching. This was completely different from daytime.

Generally speaking, when joining in the fun, you like to join in during the day, which is also safe.

With nothing to do, Bai Song went to take a look.

This is a typical case of electric vehicle battery theft. The thief climbed up the high-rise stairs and found the parked electric vehicle on the 23rd floor. He then removed the battery and left.

The timing of Bai Song's arrival was also coincidental. The person who reported the theft went downstairs to pick up the police. Because the police did not have an elevator card, they needed the person who called the police to come down and pick him up. Bai Song followed him directly.

In the elevator, he listened to the exchange between the callers.

Because it was a case of stealing electric vehicle batteries, there was no need to keep it secret, so there was nothing taboo about talking about it in the elevator.

To put it simply, the caller brought the electric car upstairs through the elevator every day and placed it in the corridor. Because I live on the 23rd floor, I thought it would be impossible for it to be stolen, so I kept leaving the car in the corridor like this. It has been fine for more than a year.

The community is not a high-end community, and the elevators are also very old, but the elevator management is still very strict. You must use an elevator card, and the elevator card can only go to your own floor.

The reason why there is such a management model is not that the property is very good, but that otherwise there is no way to collect property fees.

Of course, this kind of management model will indeed reduce the risk of theft, so the people who call the police are not too worried, but I didn't expect that there would still be such powerful thieves.

"I just took a look at your community. There are very few surveillance cameras. The main thing is that there are surveillance cameras in the elevators," the policeman said.

"There is surveillance at the gate!" the policeman said, "Wouldn't it be nice to see who went out with the electric car battery?"

"Well," the policeman said, "I arranged for our little brother to go to the security guard at the door to investigate the surveillance."

"Thank you, thank you! There are three or four hundred batteries each. It is really important to me. Our old man has been paralyzed for a long time. I just rely on me to ride to the subway station every day to help others fry skewers. We don't have an electric car. I'm in trouble." The caller was obviously worried.

"Is this building of yours all low-rent housing?" the policeman asked.

"Well, our building is, well, thank the government, otherwise we would have no way to survive."

There are basically no people jumping between floors in this building, so there are only people going down and no one going up in the middle. After passing the seventeenth floor, a person got off the elevator, and the policeman looked at Bai Song: "Are you from the 23rd floor too?"

Bai Song didn't use the elevator card and didn't press his own floor when he got up. The police were a little curious.

When the police said this, the caller immediately focused on Bai Song. At this moment, everyone looked like a thief to her. She could guarantee that she had never seen Bai Song on this floor. There are six households on each floor. Although she doesn't know them all, they are familiar with each other when taking the elevator every day. There is no young man like Bai Song on this floor.

"I live in this community. I saw some thefts here. Come and take a look. I'm also a policeman." Bai Song knew that making up things at this time would easily arouse suspicion on both sides, so he took out his police officer's ID card and showed it to the police: " If there is a thief in your neighborhood, you should check it out.”

When the police saw the police officer's ID card, they already believed that Bai Song was a police officer without specifically seeing his workplace. The main reason was that Bai Song was unlikely to be a thief. But the policeman frowned a little, thinking to himself, isn't this colleague just having nothing to do? After working as a police officer for several years, is it possible that I have never seen a case of electric vehicle batteries being stolen? Looking at Bai Song again, he felt that Bai Song was working for the agency.

Generally, only police officers working in agencies can have this kind of leisurely elegance.

The person who called the police was a little unhappy: "You said that there are thieves in the community where your policeman lives."

Faced with this sentence, Bai Song was too lazy to reply. Fortunately, because the elevator did not stop halfway, it had already reached the 23rd floor.

99% of electric vehicle battery thefts are public security cases, so it is impossible for criminal police to come to the scene to conduct an investigation. That is, the police from the police station will check and take a look. The inspection process is very simple.

The policeman took a flashlight and saw that the lock had simply been cut off with pliers, and the battery had been taken away.

"Sister, did you see this footprint? There are only the thief's footprints in the corridor on your side. There are some coming up and some going down. This means that the thief went down by the stairs, so the video cannot be found." The policeman said. He said, "Come over and take a look. If it's okay, I'll take a photo."

"Aren't there fingerprints and footprints? Comrade police, please help me."

"Well, you can come with me later to get the transcript." The policeman turned around again and found that Bai Song had left.

There is no need for an elevator card on the first floor. Bai Song just took a look at the scene and left directly.

After arriving on the first floor, Bai Song walked up the stairs to the fifth floor.

There are low-rise buildings in this kind of community, but they don't pay property fees, so they take the stairs instead of the elevator, so there are quite a lot of footprints in the corridors below the third floor. After reaching the fifth floor, Bai Song saw the thief's footprints up and down.

Previously, the police and the people who called the police believed that the thief climbed up or took someone else's elevator to a dozen floors, then climbed up, stole the battery, and then took the elevator down. But now it is certain that the thief climbed up and climbed down.

This means the thief is clearly hiding from surveillance.

A thief who can deliberately hide from surveillance cameras will definitely not leave fingerprints or anything like that, and he will wear gloves no matter what.

Then, Bai Song climbed up the steps and climbed up slowly.

Of course, this will destroy the scene, but in a case of missing batteries, the so-called scene is not important at all.

On the way, Bai Song confirmed two things.

First, when the thief climbed up, he rested twice on the 13th and 19th floors. He also left the corridor to look inside the floors. He was obviously looking for a target to steal. This means that the thief did not deliberately go to the 23rd floor. , but climbed to the 23rd floor before encountering something that could be taken action.

Second, the thief rested four times when walking down. Because the battery is very heavy, the thief often uses two steps with one foot to walk down. When resting, you can clearly see the mark of the battery pressure. There were also traces of a large pliers punched to the ground and leaning against the wall. Bai Song estimated that this type of hydraulic pliers weighed at least a dozen kilograms.

Electric vehicle batteries are generally 17 kilograms. The main components of this kind of lead-acid battery are lead dioxide, dilute sulfuric acid and other ingredients. The specific gravity is very large, so it is very heavy.

All the above are enough to prove that the thief has very good physical fitness. If nothing else, he can carry more than ten kilograms of pliers and other tools and go up to the thirteenth floor in one breath. Most people have difficulty.

When Bai Song arrived on the 22nd floor, he heard that the police and the caller were still communicating, so he didn't go up. He didn't want to cause trouble to others, so he took the elevator down from the 22nd floor.

I just climbed 22 floors in one breath, which was just a good exercise for Bai Song.

After going downstairs, it is a bit difficult to find footprints after leaving the building. In this community, only the gate and the elevator are monitored, so Bai Song believes that it is impossible for a thief to blatantly walk out of the gate with a battery.

If you don't go through the gate, it's actually very simple. The fence in the community is relatively wide. Although people can't get out, batteries and pliers can be taken in and out at will. It stands to reason that if Bai Song is a thief, he will definitely take the battery Put it with the pliers by the fence, then walk out struttingly, and then reach out and take it from the outside.

This method does not require any brain use, elementary school students can do it, and it is also an excellent way for college students to get takeout.

Ever since, Bai Song felt that there was no need to look at the gate at all. Just look for traces near the wall. After walking around for more than 20 meters, Bai Song discovered the problem.

Sure enough, the traces were obvious, just as Bai Song thought.

Taking a look with the flashlight of his mobile phone, Bai Song saw very clear shoe prints from here, and they were still Nike shoes.

Because there are vegetation and soil beside the wall here, the footprints are very clear. Bai Song stepped on them and roughly estimated the height and weight of this person.

He is estimated to be 1.8 meters tall and weighs 180-210 pounds.

If you are from East China, you can easily control the weight error to about 10 pounds.

But thinking of this, Bai Song felt something was wrong. He should lose 50 kilograms of the weight of the battery and large pliers. Then this person would be 130-160 kilograms, which can be said to be a standard figure.

Thinking of this, Bai Song called Wang Huadong. Since there were no lights here, he couldn't take a video, so he turned on the flash and took a photo and sent it over, capturing the footprints of him and the thief.

Wang Huadong told him that if the battery and pliers on his body were indeed 50 kilograms, the man's weight was estimated to be about 150 kilograms. In addition, from the comparison of the degree of soil dispersion and water infiltration of the Baisong footprints with the other footprints, The time it takes to step on that footprint will not be very long, that is, about an hour.

Logically speaking, with such a physical level and height, one shouldn't do such a thing, Bai Song frowned.

While thinking here, Bai Song saw the police going downstairs. After going downstairs, the police made a call: "There was no signal in the elevator just now. The signal in the old building over here is not good."

The person who called the police also followed the police downstairs, because he wanted to follow him back to the police station to get the transcript.

Twenty seconds later, the policeman said: "Two more incidents? I can't go, let someone else go. I have to take people back to get the transcript."

After saying that, the police immediately hung up the phone.

When Bai Song heard this, he understood what was going on. The electric vehicle battery must have been stolen somewhere nearby, and the police station did not have any extra police personnel.

Even though this is the central area of ​​Shangjing City, it is definitely not bustling everywhere. Many old buildings are on the side of the road, with a history of 20 years. Shangjing is a relatively wealthy city. Some old buildings have their exterior walls renovated and cleaned. They look very beautiful and have a good city image. However, because they are old and the residents have no money, the living environment inside is very average.

If residents don't have money, they naturally don't have good properties to settle in. Without good properties, it's already pretty good if they can guarantee water, electricity, elevators, basic camera maintenance, and doormen. As for other situations such as corridor cleaning, floor cleaning, and replacement of corridor lights, it is almost impossible.

Therefore, the police station in the central area here is extremely busy. A small police station here may have an area of ​​only 3 square kilometers, but has a permanent and floating population of more than 200,000. The number of alarms exceeds 100 every day, and the police station only has more than 40 people.

More than forty people may seem like a lot. Excluding leaders, patients, and veteran comrades over 50 years old, and excluding those on sick leave, business trips, etc., there are only four or five people who can be on duty every day to handle cases and call the police.

In order to maintain duty, many police stations in Beijing need to be on duty once every three days.

Being on duty for three days does not mean working one day every three days, but being on duty 24 hours today. You can take a nap tomorrow morning, work on yesterday's case in the afternoon, and go to work normally the day after tomorrow, handling some cases and community work, etc. In addition, there are many duties. Then on the fourth day, they will continue to be on duty for 24 hours, and the cycle will last three days.

Beijing's geographical location is special, and there are many international events, large-scale events, concerts, trips for big leaders, etc., so the workload is huge.

Under this circumstance, it is inevitable that the detection rate of cases such as electric vehicle battery theft will be low.

And even if a person is caught, the follow-up interrogation, price appraisal, search for dirt, interrogation, inspection, criminal history inquiry, collection of dirt, physical examination, detention, etc. will require at least four people to work for a whole day. In the end, it will only be detained for ten days. .

After this person is released, he continues to steal.

This policeman was obviously an old policeman, so he hung up the phone directly. He didn't want to go to the other two police cases. He was too tired. He took this back and talked about it later.

But just as he walked to the doorman, the call came again. He picked up the phone and listened for a few words. It was the deputy director on duty calling.

There was no other way. There was really no one left. He could only violate the regulations and go to the place where the two batteries were stolen to call the police alone. He asked the person who adjusted the surveillance here to stop doing so. He took the victim back to the police station to get the transcript and accept the case. .

Seeing this situation, Bai Song went to the guard at the door and told the police that he could help take a look at the surveillance camera. The two policemen were in a hurry to leave and thought it was nothing, so they asked Bai Song to look at the surveillance camera.

The police below had quickly moved in to make sure no one was walking out with the battery, because it was very conspicuous. After telling Bai Song about the situation, they left directly.

Bai Song ignored this information. He started to see who went out from here within half an hour to an hour. Their height and weight matched and their shoes were stained with mud.

Because the person holding the battery was heavy and stepped on it relatively deeply, and he was wearing sneakers, it was normal for there to be mud on the sides of the shoes.

Fast forward four times, and in less than five minutes, Bai Song found the image of the thief.

The thief was not ugly, he was a young, strong man. This made Bai Song a little confused. Why would such a person become a thief? How much can you sell a stolen battery for?

After obtaining the video, Bai Song took the photos and videos and sent them directly to Wang Liang, asking Wang Liang to help find someone through the Skynet system.

I have to say that this is indeed not too difficult. There are not many videos in these communities in Shangjing, and there are many cameras on the roads. In less than twenty minutes, Wang Liang gave Bai Song the thief's foothold.
