Chapter 36 Gold Pink Hermès
The eight cameras in Jiangcun Community cover the entrance and exit and two electric vehicle parking spots inside and outside.
The electric vehicle parking spot inside is covered with an awning, and the open-air street outside does not affect the thieves' enthusiasm.
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 is a man in a jacket who may have fingerprints on the bottom of the I-beam. He looks like he is in his twenties. He basically uses a master key to violently unlock the door. After coming here a few times, he stopped coming. He is probably afraid of being caught by the security guard. 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 was installed, and the speaker was attached with a magnet. Once the alarm was resolved, it was immediately moved away. For locked electric vehicles, use hydraulic pliers to cut the chain lock or U-shaped lock that locks the vehicle, and then move it onto a tricycle to steal multiple electric vehicles at once.
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. If you swerve, it is equivalent to leaving the city. Xundu Nowhere to look.
"It's all so technical." After watching the surveillance video, Jiang Yuan copied the scene of the transport team throwing cigarette butts and garbage into the roadside drainage ditch onto his mobile phone. I couldn't help but comment.
What he had imagined or believed before was that driving an electric car required at least lock-picking skills. This was not reflected in either group.
Moreover, from the perspective of efficiency and practicality, the methods used by these two groups are actually better than the unlocking mode.
Because technical unlocking always takes some time. No matter how fast you open the lock, it is just like the violent unlocking in the first group. It can't be opened faster by turning it twice. And if the speed of technical unlocking is slower, people will still be suspicious of it.
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."
"Let's just say, these three people still have pursuits in the end?"
"No. These two use hydraulic pliers. If you look closely, they all prioritize 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 he said it quite clearly.
For things like anti-theft, in the final analysis, we 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 jackets. As long as the lock position is correct, the 60-yuan U-shaped lock can probably prevent the jacket, but it cannot prevent the moving flow of hydraulic pliers.
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. It is like the "example questions" in the book. No matter how difficult the example questions are, it can only guard against those who do not 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 doesn't need to be improved or improved. As long as the location is changed and the mode is changed a little bit, the success rate of anti-theft will be greatly improved. It's like slightly modifying the example questions in the book, changing numbers or something, which is enough to block students who don't study hard 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. You will know that any child who can score 120 points on the math test will not be able to solve the problem no matter how bad it is. 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 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 all kinds of work and can do any job. Wearing a duty uniform with a police number starting with FJ, Zhou Ta is over 40 years old and has 15 years of police experience.
Zoumadao Police Station was also afraid that 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 say it and we can 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 eventually 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, and there was no need to act as a debt of gratitude.
What's more, Jiang Yuan doesn't understand the things on the street, so he owes favors for this, and he doesn't know how complicated it is.
Zhou Ta confirmed Jiang Yuan's attitude in a few words and entered the chat environment with a smile. He patrols the neighborhood every day, and he knows exactly which store has clean food and which supermarket has rats, which is quite 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?" ”
"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, just scan the powder."
As he spoke, Jiang Yuan took out one containing gold powder from several gold, silver, black and gray bottles, and then took 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.
"Technical people are different. You are quite particular. 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, it is easier to do it yourself than to ask someone 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. It is better to use gold powder for contrast."
"Your brush seems to be different too."
"Pure squirrel hair. It costs more than 200. I specially asked for it."
"This broken brush costs more than 200?" Mu Zhiyang was surprised.
"Squirrel hair is known as 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 eye shadow to a beautiful woman.
As the excess gold powder dispersed, a few incomplete fingerprints appeared in front of the two of them.
