It was almost eight o'clock in the evening. It was dark early in this season and no one was interested in watching the police. It was completely different from the daytime.
Generally speaking, when people are going out to have fun, they prefer to go out during the day, which is also safe...
Bai Song had nothing to do, so he went to have a look...
This was a typical case of electric vehicle battery theft. The thief climbed up the high-rise stairs one floor at a time and found a parked electric vehicle on the 23rd floor. He then removed the battery and left.
Bai Song's arrival was quite coincidental. The person who had reported the theft came downstairs to meet the police. As the police did not have an elevator card, the person who called the police needed to come down to meet them, so Bai Song followed him directly.
In the elevator, he listened to the conversation between the person who called the police.
Since it was a case of stealing electric vehicle batteries, there was no need to keep it confidential, so there was nothing to be shy about talking about it in the elevator.
Simply put, the person who called the police took the electric bike upstairs via the elevator every day and placed it in the corridor. Because he lived on the 23rd floor, he thought it was impossible for it to be stolen, so he kept the bike in the corridor like this for more than a year without any problems.
The community is not a high-end one and the elevators are very old, but the elevator management is still very strict. You must use the elevator card, and the elevator card can only go to your own floor.
The reason for this management model is not that the property is so good, but that the property fees cannot be collected at all without it.
Of course, such a management model does reduce the risk of theft, so the person who called the police was not too worried, but he did not expect that there were still thieves so powerful.
"I just checked your community, and there are very few surveillance cameras. The main surveillance cameras are in the elevators," said the police.
"There are surveillance cameras at the gate!" the caller said, "Wouldn't it be good to see who took the electric bike battery out?"
"Well," the policeman said, "I arranged for our young men to go to the security guard at the door to investigate the surveillance."
"Thank you, thank you! This battery costs three or four hundred yuan each and is really important to me. My old man has been paralyzed for a long time, and I rely on him to ride my bike to the subway station every day to help others fry skewers. I would be in trouble without an electric bike." The person who called the police was obviously a little anxious.
"Is this building full of low-rent housing?" the policeman asked.
"Well, our building is...thank the government, otherwise we would have no way to survive."
There was basically no one jumping between floors in this building, so people would only go down and no one would go up. After the 17th floor, when someone got off the elevator, the police looked at Bai Song and asked, "Are you also on the 23rd floor?"
Bai Song did not use the elevator card and did not press his own floor button when he came up, so the police became curious.
After the police said this, the caller immediately stared at Bai Song. At this moment, everyone looked like a thief to her. She was sure that she had never seen Bai Song on this floor. There were six households on each floor. Although she didn't know them all, she would be familiar with them because she took the elevator every day. There was no young man like Bai Song on this floor.
"I live in this neighborhood. I saw a thief here, so I came to check it out. I'm also a policeman." Bai Song knew that making up a story at this time would easily arouse suspicion from both parties, so he took out his police officer ID and showed it to the police: "There is a thief in my neighborhood, so I have to check it out."
The police saw the officer's ID card, but didn't see any specific work unit, so they believed that Bai Song was a policeman. The main reason was that Bai Song didn't look like a thief. But the police frowned, thinking that this colleague was just idle and had nothing to do. After working as a policeman for several years, had he never seen a case of electric vehicle battery theft? Looking at Bai Song again, he felt that Bai Song worked in a government agency.
Generally, only police officers working in government offices have this kind of leisure and elegance.
The person who called the police was not happy: "You said there are thieves who come to steal in the neighborhood where you police officers live."
Faced with this sentence, Bai Song was too lazy to reply. Fortunately, the elevator did not stop halfway and had reached the 23rd floor at this time.
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. The police from the police station will check and take a look, and the inspection process is very simple.
The police shone a flashlight and found that the lock was simply broken with pliers and the battery was taken away directly.
"Sister, did you see these footprints? There are only the thief's footprints in the corridor on your side. Some are coming up, and some are going down. This means that the thief went down the stairs, so the video can't find him." The police said, "Come and take a look. If there is no problem, I will take a photo."
"Aren't there fingerprints and footprints? Police officer, please help me."
"Well, come with me to get a statement later." The police turned around again and found that Bai Song had left.
There was no need for an elevator card to go to the first floor. Bai Song just took a look at the scene and left.
After reaching the first floor, Bai Song walked up the stairs to the fifth floor.
In this kind of community, people on the lower floors do not pay property fees and use the stairs instead of the elevator, so there are many footprints in the corridors below the third floor. After reaching the fifth floor, Bai Song saw the thief's footprints going up and down.
Previously, the police and the person who called the police believed that the thief either climbed up or took the elevator pressed by someone else to the top ten floors and then climbed up again, stole the battery, and then took the elevator down. But now it can be confirmed that the thief climbed up and climbed down.
This means that the thief was clearly trying to avoid surveillance.
A thief who is so deliberate in avoiding surveillance would definitely not leave fingerprints or anything, and would at least wear gloves.
Then, Bai Song climbed up the stairs slowly.
This would certainly destroy the scene, but in a case of a missing battery, such a 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, and he also left the corridor to look around 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 only found something to steal after climbing to the 23rd floor.
Second, the thief rested four times when he walked down from the top. Because the battery was very heavy, the thief often walked down by taking two steps with one foot. When he rested, you could clearly see the marks of the battery pressure and the traces of a large pair of pliers sticking to the ground and against the wall. Bai Song estimated that this kind of hydraulic pliers weighed at least ten pounds.
Electric vehicle batteries generally weigh 17 kilograms. The main components of this type of lead-acid battery are lead dioxide, dilute sulfuric acid and other ingredients, which have a large specific gravity, so they are very heavy.
All of the above is enough to prove that the thief has very good physical fitness. Not to mention, he can carry a pair of pliers weighing more than ten pounds and other tools and go up to the thirteenth floor in one breath, which is difficult for most people.
When Bai Song reached the 22nd floor, he heard the police upstairs still communicating with the person who called the police, so he did not go upstairs. Not wanting to cause trouble for others, he took the elevator down from the 22nd floor.
I just climbed 22 floors in one breath, which was a good exercise for Bai Song.
After going downstairs and leaving the building, it was a bit difficult to find footprints. This community only has surveillance cameras at the gate and in the elevator, so Bai Song believed that it was impossible for the thief to walk out of the gate with the battery in his arms.
If you don't go through the main gate, it's actually very simple. The fence of the community is relatively wide. Although people can't get out, batteries and pliers can be taken in and out at will. Logically, if Bai Song was a thief, he would definitely put the batteries and pliers next to the fence, then walk out swaggeringly, and then reach in and take them away from the outside.
This method does not require any brainpower at all, even elementary school students can do it, and it is also a great way for college students to get takeout.
So, Bai Song felt that there was no need to look at the gate at all, and it would be OK to look for traces near the wall. After walking around the area for more than 20 meters, Bai Song found the problem.
Sure enough, the traces were obvious, just as Bai Song had thought.
Using the flashlight on his cell phone, Bai Song saw a very clear shoe print from this side, and it was a Nike shoe.
Because there was vegetation and soil next to the wall, the footprints were very clear. Bai Song stepped on them and roughly estimated the person's height and weight.
His height is estimated to be 1.8 meters and his weight is 180-210 kilograms.
If it were Huadong, the weight error could be easily controlled within about 10 kilograms.
But thinking of this, Bai Song felt something was wrong. He should reduce the weight of the 50-pound battery and the large pliers. Then this person would be 130-160 pounds, which could be said to be a standard body shape.
Thinking of this, Bai Song called Wang Huadong. Because there was no light here, he couldn't video chat, so he just turned on the flash and took a photo and sent it over, capturing his and the thief's footprints.
Wang Huadong told him that if the battery and pliers on his body really weighed 50 kilograms, the man's weight was estimated to be around 150 kilograms. In addition, judging from the degree of soil diffusion and water penetration of Bai Song's footprints compared with the other footprints, that footprint would not have been there for a long time, only about an hour.
Logically speaking, with his physical level and height, he shouldn't do this kind of thing, so Bai Song frowned.
While thinking about this, Bai Song saw the police coming downstairs. After going downstairs, the police made a phone call: "There was no signal in the elevator just now. This is an old building, and the signal is not good."
The person who called the police also followed the police downstairs to go back to the police station to get a statement.
After twenty seconds, the policeman said, "Two more cases? I can't go. Let someone else go. I have to take people back to collect statements."
After saying that, the police hung up the phone.
When Bai Song heard this, he understood what was going on. It must be that electric vehicle batteries had been stolen somewhere nearby, and the police station had no extra police force.
Even though this is the central area of Shangjing City, it is definitely not prosperous everywhere. Many old buildings are on the side of the main road, and they are easily 20 years old. Shangjing is a relatively wealthy city, and some old buildings have their exterior walls renovated and cleaned, which looks very beautiful and has a good image for the city. However, due to their age and the fact that the residents have no money, the living environment inside is very average.
If the tenants have no money, naturally there will be no good property management to move in. Without good property management, it is already very good if it can guarantee water, electricity, elevators, basic camera maintenance and door guards. As for other things like cleaning the corridors, cleaning the floors, changing the corridor lights, etc., it is almost impossible.
Therefore, the police stations in the central area here are extremely busy. A small police station here may have a jurisdiction of only 3 square kilometers, but the permanent and floating population exceeds 200,000, and the number of alarm calls exceeds 100 every day, but the police station has only more than 40 people.
More than 40 people may seem like a lot, but excluding leaders, patients, old comrades over 50 years old, and those on sick leave or on business trips, the number of people who can be on duty and respond to cases every day is, at most, four or five.
In order to maintain their duty, many police stations in Beijing need to be on duty once every three days.
Three-day duty does not mean working one day every three days, but working 24 hours today, taking a nap tomorrow morning, dealing with yesterday's cases in the afternoon, and going to work the day after tomorrow to handle some cases and community work, etc. In addition, there are a lot of duties. Then the fourth day is another 24-hour duty, and the cycle repeats every three days.
Shangjing has a special geographical location, and there are a lot of international activities, large-scale events, concerts, travel of senior leaders, etc., so the workload is very heavy.
In this case, it is inevitable that the detection rate of cases such as electric vehicle battery theft is low.
And even if the person is caught, the subsequent interrogation, price appraisal, search for dirty items, questioning, inspection, criminal record check, confiscation of dirty items, physical examination, detention, etc. will require at least four people to work for a whole day, and in the end, the detention is only ten days.
After this man was released, he continued to steal.
This policeman was obviously an old hand. He hung up the phone directly. He didn't want to continue to deal with the other two cases. It was too tiring. He decided to take this one back first.
But just as he walked to the guard post, the phone rang again. He picked up the phone and listened to a few words. It was the deputy director on duty calling.
There was no other way, there was really no one around, so he could only violate the regulations and go to the place where the two batteries were stolen alone to respond to the call. He asked the person who was checking the surveillance camera to stop for the time being and take the victim back to the police station to obtain a statement and handle 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. The two policemen were in a hurry to leave and thought it was nothing, so they let Bai Song watch the surveillance.
The police below had just fast-forwarded to make sure no one was walking out with the battery, as it would be very conspicuous. After telling Bai Song about this, the two of them left immediately.
Bai Song ignored this information and started looking for someone who would walk out from here within half an hour to an hour, with the right height and weight and with mud on his shoes.
Because the man was holding a heavy battery and stepped quite deep, and he was wearing sneakers, it was normal for there to be mud on the edges of his shoes.
Fast forwarding at four times the speed, Bai Song found the image of the thief in less than five minutes.
The thief was not ugly, he was a young and strong guy, which made Bai Song a little confused. Why would such a person become a thief? How much money could he get from stealing batteries?
After obtaining the video, Bai Song took photos and videos and sent them directly to Wang Liang, asking Wang Liang to help find the person through the Skynet system.
I have to say that this was indeed not too difficult. There were not many videos in the residential areas in Beijing, but there were many cameras on the roads. In less than twenty minutes, Wang Liang had given Bai Song the whereabouts of the thief.
