The 8 cameras in Jiangcun Community cover the entrance and exit and 2 electric vehicle parking spots inside and outside.
The electric vehicle parking spot inside is covered with a canopy, and the outside is open to the street, which does not affect the enthusiasm of thieves.
After watching the video surveillance for a long time, Mu Zhiyang and Jiang Yuan discovered that there were three people in total who came to steal the battery car.
One was a man in a jacket who might have fingerprints on the bottom of the I-beam. He looked about 20 years old. He basically used a master key to violently unlock the door. After coming here a few times, he stopped coming. He was probably afraid of being caught by the security guards.
Recognize something like that.
The other two people in a group were even more violent. They came twice in total. They drove an electric tricycle over at night and parked it next to the electric vehicle parking spot outside the door. When they saw an electric vehicle with an unlocked stake, they cut off the battery.
The fuse is attached to the horn with a magnet. Once the alarm is resolved, the vehicle is moved away directly. If the electric vehicle is locked, use hydraulic pliers to cut off the chain lock or U-shaped lock that locks the vehicle, and then move it onto the tricycle and steal it all at once.
Multiple electric vehicles.
Jiangcun community belongs to the edge of the county. The south bank where the county government is located is relatively prosperous. The north bank is full of newly built residential communities and streets with incomplete facilities. The criminal suspect stole the electric car. He who dangled back and forth was equivalent to leaving the city. Xundu
Nowhere to look.
"It's all so technical." Jiang Yuan couldn't help but comment after watching the surveillance video, and then copied the image of the transport team throwing cigarette butts and garbage into the roadside drainage ditch on his mobile phone.
What he had imagined or believed before was that driving an electric car required at least lock-picking skills, but this was not reflected in either group.
Moreover, from the perspective of efficiency and practicality, the methods adopted by these two groups are actually better than the lock-picking mode.
Because technical unlocking always takes some time. No matter how fast the unlocking is, it is just like the violent unlocking in the first group. It can't be opened faster after turning twice. And if the speed of technical unlocking is slower, it will not work well.
Still need to be suspected.
Mu Zhiyang said cheerfully: "You've already stolen electric cars, what skills can you have? There are even worse ones. They don't even know how to violently unlock the door. They just wander on the street to see whose electric car has forgotten the key."
, sit on it immediately and drive away..."
"What if we don't encounter an electric car that forgets to take out the key?"
"Go home, make some noodles, and continue playing with your phone." Mu Zhiyang curled his lips and said, "There are also people who specialize in stealing batteries, but they are not much more advanced than this."
"Just saying, these three people still have pursuits in the end?"
"No. These are the two who use hydraulic pliers. If you look carefully, they all give priority to cutting the lock head. Why? Because the lock fork can be made very hard, but the shape of the lock head is complicated, so the hardness cannot be high. High
It can't be processed, or it's too expensive to process, that's what it means..." Mu Zhiyang also relayed what he heard, but what he said was quite clear.
In the final analysis, when it comes to things like anti-theft, you still have to pay attention to cost-effectiveness.
A 20-yuan U-shaped lock can only protect against passers-by, but cannot protect against violent unlocking such as assault jackets. A 60-yuan U-shaped lock can probably protect against assault jackets as long as the lock position is correct, but it cannot protect against hydraulic pliers.
kind of moving flow.
The same goes for the alarm system that comes with an electric vehicle. An alarm with its own power supply is more practical than an alarm connected to the battery. An alarm with two speakers is more troublesome than one with one speaker. However, no matter how good it is,
The anti-theft system is afraid of meeting the right person, especially the standard anti-theft system, which is like the "example questions" in the book. No matter how difficult the example questions are, it can only guard against those who don't read books, but cannot guard against those who are smart and eager to learn.
The best anti-theft mode for electric vehicles is for car owners to make some personalized changes to the anti-theft system of their own cars. It does not need to be modified or improved. As long as the position is changed and the mode is changed a little bit, the anti-theft success rate will be greatly improved.
.This is like slightly modifying the example questions in the book, changing the numbers and so on, which is enough to block those students who do not study seriously or are not smart enough to learn.
However, they are all reduced to stealing electric cars. They only study hard and are smart and eager to learn. Just look at the clues they left and you will know. As long as a child who can score 120 points on the math test, no matter how bad the questions are,
It's impossible to be so careless.
Jiang Yuan and Mu Zhiyang each rode an electric bicycle and first went to the Zouma Road Police Station next to Jiangcun Community to report.
After some communication with Comrade Mu Zhiyang, the two of them successfully led an auxiliary police officer to accompany them.
Although the auxiliary police officer has the word "auxiliary", in the current grassroots judicial system, he has to do any job and can do any job. Zhou Ta, who is wearing a duty uniform with a police number starting with FJ, is over 40 years old.
He has 15 years of police experience.
Zoumadao Police Station was also afraid that two young men, Jiang Yuan and Mu Zhiyang, were ignorant, so they dispatched Zhou Ta.
Compared with ordinary policemen, Zhou Ta's communication skills are quite good. After walking for a while, he became familiar with Jiang Yuan and Mu Zhiyang, and then said: "I also often do on-site investigation work. In fact, if I just scan fingerprints,
, just tell us, we can just go over and scan it, there is no need to come here specially..."
"I want to scan it myself." Jiang Yuan explained politely: "The fingerprints on the I-beam are a month old. I don't know if they can still be scanned out."
When Zhou Ta heard this, he immediately stopped the topic and said instead: "Actually, you don't have to scan fingerprints. You might be able to find someone by asking around on the street. These people who steal electric cars for food have nothing to do with them.
.If you are willing to put in the effort, someone will always reveal it."
"Then try next time." Jiang Yuan was just helping his relatives find electric cars. Asking Mu Zhiyang and Zhou Ta to make a trip was already troublesome. There was no need to act as a debt of gratitude.
What's more, Jiang Yuan doesn't understand what's going on on the street, so he owes a favor, and he doesn't know how complicated it is.
Zhou Ta confirmed Jiang Yuan's attitude in a few words, and then entered the chat environment with a smile. He patrolled the neighborhood every day, and he knew exactly which store had clean food and which supermarket had rats.
Pretty interesting.
When they arrived at the scene, Zhou Ta, who was wearing duty uniform, was very motivated to take notes on the scene. Mu Zhiyang followed Jiang Yuan and squatted in front of the I-beam, bent down and took a look, and said, "How can you tell if there are any fingerprints here?"
Already."
"You can use a magnifying glass or ultraviolet light to see." Jiang Yuan opened the survey box he brought with him and said casually: "In our situation today, we don't have to go to so much trouble. We can just scan the powder."
As he spoke, Jiang Yuan was seen ordering his troops, taking out a bottle containing gold powder from several gold, silver, black and gray bottles, and then taking out a fluffy wine-black brush.
Looking again at the location of the reproduced photo, Jiang Yuan dipped a brush into gold powder and gently flicked the brush handle, causing the 400-mesh copper powder to fall densely onto the relatively flat steel surface.
From Mu Zhiyang's point of view, Jiang Yuan's playing was particularly even, and in conjunction with his intro, it was actually quite ritualistic.
"It's different for those who work in technology. You are quite particular about this. We usually use silver powder." As a criminal police officer, Mu Zhiyang often scans for fingerprints when he appears on the scene. For some small cases, he can do it himself.
Yes, it's easier than asking people from the Criminal Division Squadron to come over.
Jiang Yuan observed the surface of the I-beam and said: "Silver powder has strong adhesion and is suitable for many occasions. It is considered an all-purpose powder. But today's background is too light, and the contrast with gold powder is better."
"Your brush seems to be different too."
"Pure chinchilla hair. It costs more than 200 each. I specially asked for it."
"This broken brush costs more than 200?" Mu Zhiyang was surprised.
"Squirrel hair is called the Hermès of brushes." Jiang Yuan shook the brush and said with a smile: "Look at the tips of the hairs, they are thin, straight, and soft, and they are not easy to damage fingerprints."
"Is this Hermès?"
"Because among the makeup brushes used by girls, chinchilla hair is also the best. It is comfortable for brushing fingerprints, and it is also comfortable for girls' faces to be brushed with it." Jiang Yuan then added: "It goes best with gold powder."
As Jiang Yuan spoke, he lay down, leveled his right hand, and used the tip of a chinchilla brush to gently brush off the gold powder on the surface of the I-beam, as gently as applying eyeshadow to a beautiful woman.
As the excess gold powder dispersed, a few incomplete fingerprints appeared in front of the two of them.
