Chapter 36 Gold Powder Hermes

The 8 cameras in Jiangcun Community include the entrance and exit and 2 electric vehicle parking spots inside and outside.

The electric car parking place inside has a canopy, and the outside is open to the street, which does not affect the enthusiasm of the 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 is a man in a jacket who may have fingerprints on the bottom of the I-beam. He looks about 20 years old. He basically uses a master key to open the lock violently. recognized by the class.

The other two were in a group, which was more violent. They came here twice in total. They drove an electric tricycle over at night and parked it next to the electric bicycle parking spot outside the door. The fuse, and then use a magnet to paste the horn, and remove it directly after the alarm is resolved.For electric vehicles with piles locked, use hydraulic pliers to cut off the chain lock or U-shaped lock that locks the vehicle, and then put it on a tricycle to steal multiple electric vehicles at a time.

The Jiangcun community belongs to the fringe area of ​​the county seat. The south bank where the county government is located is relatively prosperous, while the north bank is a newly built residential area and streets with incomplete facilities. The criminal suspects stole the electric car. I can't find it anywhere.

"It's all without technical content." Jiang Yuan watched the surveillance video, and copied the picture of the transport team throwing cigarette butts and garbage into the roadside gutter into his mobile phone.Can't help but comment.

What he imagined, or thought before, that driving an electric car requires at least unlocking skills, was not reflected in the slightest in either group.

Moreover, from the perspective of efficiency and practicality, the methods used by these two groups are even better than the unlocking mode.

Because technical unlocking always takes a little time, no matter how fast the lock is unlocked, it is nothing more than the same as the violent unlocking of the first group. It cannot be opened faster by turning it twice.And if the speed of technology unlocking is slower, people will be suspicious if it is not done well.

Mu Zhiyang said cheerfully: "I've already stolen the electric car. What kind of technology do you have? There are even worse ones, who don't even know how to brute force the lock, just wandering on the street to see who forgot to pull out the key of the electric car , immediately sit up and drive away..."

"What if there is no electric car that forgot to pull out the key?"

"Go home and 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, they are not much more advanced than this."

"In other words, these three people still have pursuits in the end?"

"That's not true. Just look at these two 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. If 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 clearly.

For things like anti-theft, in the final analysis, it is still necessary to pay attention to cost performance.

A 20-yuan U-shaped lock can only prevent passers-by, but not violent unlocking like jackets. As long as the U-shaped lock of 60 yuan is in the correct position, it can probably prevent the jacket, but it cannot prevent the movement of hydraulic pliers.

The same is true for the alarm system of electric vehicles. 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. 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 prevent those who do not read the book and those who are smart and eager to learn.

The best anti-theft mode for electric vehicles is that the owner makes some personalized changes to the anti-theft system of his car.It doesn't need to be improved or improved, as long as the position is changed and the pattern is changed a little, the success rate of anti-theft will be greatly improved.It's as if a little modification of the example questions in the book, changing the numbers or something, is enough to stop those students who haven't studied hard or are not smart enough to learn.

However, it has been reduced to stealing electric cars, the level of serious study, the level of being smart and eager to learn is just that, just look at the clues they left behind, as long as the child who can score 120 points in mathematics, no matter how sloppy the subject is, It's impossible to be so careless.

Jiang Yuan and Mu Zhiyang each rode an electric bicycle, and first went to the Zoumadao police station next to the Jiangcun community to report.

After some communication with Comrade Mu Zhiyang, the two successfully led an auxiliary policeman to accompany them.

Although auxiliary police carry an auxiliary word, in the current grassroots judicial system, they have 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 and has 15 years of police experience.

The Zoumadao police station dispatched Zhou Ta because they were afraid that Jiang Yuan and Mu Zhiyang would be ignorant.

Compared with ordinary policemen, Zhou Ta's communication skills are quite good. After walking for a while, he got acquainted with Jiang Yuan and Mu Zhiyang, and then said: "I also often do on-site investigations. In fact, if it's just scanning fingerprints , just tell me, we just go over and scan it, there is no need to come here specially..."

"I want to scan it myself." Jiang Yuanke explained politely: "The fingerprint on the I-beam has been there for a month. I don't know if it can still be scanned."

When Zhou Ta heard this, he immediately stopped the topic, and changed his mind: "Actually, you don't necessarily have to scan your fingerprints. If you go to the street to inquire, you may be able to find someone. Those who steal electric cars for dinner have nothing to do with them." .If you are willing to work hard, someone will confess."

"Then try it next time." Jiang Yuan was just helping his relatives find electric cars. It would be too troublesome to ask Mu Zhiyang and Zhou Ta to take a trip.

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 with a few words, and entered the chatting environment with a smile.He patrols the neighborhood every day, and he knows exactly which store has clean food and which supermarket has rats, and what he said is quite interesting.

When he arrived at the scene, Zhou Ta, who was wearing a duty uniform, was very motivated to take notes on the spot. Mu Zhiyang followed Jiang Yuan and squatted in front of the I-beam, bent over and took a look, and said, "How do you see if there are any fingerprints?" gone."

"You can use a magnifying glass or ultraviolet light to see." Jiang Yuan opened the inspection box he brought with him, and said casually: "In our current situation, it doesn't need to be so troublesome, just sweep the powder."

While talking, Jiang Yuan seemed to be ordering his troops, and from several gold, silver, black and gray bottles, he took out one containing gold powder, and took out a fluffy wine black brush.

Taking another look at the position of the reproduced photo, Jiang Yuan dipped a brush into the gold powder, and flicked the handle of the brush gently, so that the 400-mesh copper powder fell onto the relatively flat steel surface.

From Mu Zhiyang's point of view, Jiang Yuan's playing was exceptionally even, and his prelude was quite ceremonial.

"Technology is different. You are quite particular. We usually use silver powder." As a criminal policeman, Mu Zhiyang also had to scan his fingerprints frequently when he appeared on the scene.For some small cases, it is easier to do it yourself than to invite 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 can be regarded as an all-purpose powder. But today's background is too light, and it is better to use gold powder for comparison."

"Your brush seems to be different."

"Pure squirrel hair. There are more than 200 ones. I want to come out specially."

"This broken brush is more than 200?" Mu Zhiyang was surprised.

"Squirrel hair is known as the Hermes in the brush." ​​Jiang Yuan flicked the brush and said with a smile: "Look at the tip of the hair, it is thin, straight, and soft, and it is not easy to damage fingerprints."

"Is this Hermes?"

"Because among the makeup brushes used by girls, squirrel hair is also the best. It is comfortable to brush fingerprints, and girls' faces are also comfortable to be brushed by it." Jiang Yuan then added: "It is the best match with gold powder."

Jiang Yuan talked, got down on his knees, leveled his right hand, and used the tip of the squirrel brush to gently wipe off the gold powder on the surface of the I-beam, as gently as if he was applying eye shadow to a beautiful woman.

As the excess gold powder dispersed, several incomplete fingerprints appeared in front of the two of them.
