Chapter 216 Unlock

Outside.

Huang Qiangmin began to take notes for a group of people.

Previously, when the two fat and thin surveyors from Qinghe City came, they had already made notes for them, but Huang Qiangmin still had to do it again.

Although Yuan Jiansheng also found it troublesome, he still cooperated as much as possible.

With him as an example, no matter how unwilling others are, they have to follow suit.

It took Huang Qiangmin several hours to complete the transcripts of more than [-] people, even if he had focused inquiries.

Everyone is exhausted.

Huang Qiangmin also tried his best to cheer up and finished the transcript before entering the mansion.

The luxurious decoration could not arouse his interest in the slightest. He had also seen the luxurious mansions that Wu Jun had seen, and even the dreams Wu Jun had had, he had had similar ones, but Guan Erye didn't bless him that's all.

"How did you do?" Huang Qiangmin came outside the study and saw that the door had been cordoned off, so he stood outside the cordon, looked at the busy people inside, and asked, "Can we get any evidence?"

Hearing the voice, Jiang Yuan straightened his back, said with a "huh" and said, "I picked a lot."

"Has the trace of the evidence been removed?" Huang Qiangmin asked.

"A little bit, but not much." Jiang Yuan said.

Huang Qiangmin frowned unsurprisingly: "The crime was committed internally?"

"It's hard to tell." Jiang Yuan turned around and took another fingerprint.

Fatty was spreading powder beside him, and Wu Jun and Shou Xiankan next to him were sweeping desks and other things, so as not to bend over and die in pain.

Huang Qiangmin sighed: "This kind of family business is more troublesome. Now, the boss and the third child of their family are holding important positions in the company, and the confrontation has been fierce recently, and the suspicion of entering the study to make small moves cannot be ruled out. In addition, The company also has other original shareholders and management, and they probably have their own ideas about the upcoming listing."

"By the way, there is also the issue of information disclosure." Huang Qiangmin summed up the information he had gained, and said: "Many people in Jianyuan Company are not very clear about the listing situation, and there is also a huge room for arbitrage Yes, it is also possible to collect some information for this..."

After Jiang Yuan took his fingerprints, he looked up at Huang Qiangmin and said, "There are still a lot of property missing."

"Compared to the value of these documents, it's a drop in the bucket." Huang Qiangmin said.

"For the thief, it is enough. Among the lost items, there are suet jade handles, emerald paperweights, cash, watches, luxury pens, and computer accessories, all of which are of high value. thing."

"What do you mean?" Huang Qiangmin's thoughts were somewhat affected by the image of the recording just now. He hasn't done a case for a while, especially after Jiang Yuan came. The case detection rate in Ningtai County is extremely high, and the relatively large discovery The case can basically be solved smoothly, which makes Huang Qiangmin almost out of the first-line state.

However, Jiang Yuan's explanation made Huang Qiangmin smell something different.

Jiang Yuan didn't hold back any more, took out his mobile phone, drew a few photos, handed them to Huang Qiangmin, and said, "The study door has traces of technology unlocking."

The picture Huang Qiangmin saw was the inner wall of the keyhole taken by Jiang Yuan.

Another light source was used next to it to light up, and a little bit of scratches on the inner wall were vaguely photographed.

Huang Qiangmin didn't take it too seriously. He didn't have any professional skills in this area, so he just asked intently: "How did you drive it?"

"Hook the marble to unlock it." Jiang Yuan gave the answer.

There are many ways to unlock the technology. Sometimes watching movies, it seems that there are many ways.

In fact, there are only 6 ways to use technical means to steal door locks or mechanical locks.

The simplest and most common one is to unlock the door with the insert, which is often shown in various small videos, in which a bank card is used to open the door lock.This requires that the door is not locked, and the door gap is relatively large.It is the most basic and weakest way to pick a lock.

The second is strong unlocking, which is a commonly used solution when electric vehicles are stolen, directly twisting the lock, which requires the lock cylinder to be weak enough.

In addition, there are sets of locks, which can be unlocked through the cat's eye or the long handle in the lower door, and unlocked with stolen keys.

The above five types can be mastered by ordinary people with a little study, at most dozens of hours.Those who are talented can learn to become teachers in a few hours.

But these five ways of unlocking, in the final analysis, all use the defects and negligence of the door lock, the door or the key holder to unlock.

The truly technical and universal unlocking method is what Jiang Yuan called "unlocking with a bullet".

Its principle is to insert the crochet needle into the lock hole, simulate the unlocking principle of the key, and adjust the position of the pin of the lock cylinder to unlock the lock.Because all marbles have chamfers at both ends when they are being processed, use a special tool to move the first class marble, borrow the gap between the size error of the marble, you can dial it to the unlocked position, and then use a special tool to lock it , do not allow the first pin to return, and then use another crochet hook to continue to dial the second pin, and operate in this order, all the pins can be set to the unlocked position.

At this time, for the lock cylinder, it is equivalent to being poked tightly by the key.

Therefore, in this way, unless it is a lock without a key, as long as the technology is skilled enough, there is nothing that cannot be opened.

However, even if you are skilled, it will take a long time to unlock a lock without obvious defects, especially a high-grade lock with protection.

As in the movie, locks that can be opened in minutes are theoretically not of sufficient quality to be unlocked with a tumbler. You can directly force the lock or open the lock with a sleeve, and there is no need to use the tumbler to open the lock.

If judged by the technical level, if you have mastered 5 kinds of unlocking schemes and can occasionally use a hook to unlock the lock, it is considered to be at the LV1 level of unlocking.And to be able to open Yuan Jiansheng's study door, at least the LV2 lockpicking skill is required.

In other words, Yuan Jiansheng's study door was opened by a professional thief.

Huang Qiangmin turned his mind quickly, among the 30 or so people who were trapped in the yard just now, is there any professional thief?

It is said that there is no such thing.Even if someone's hobbies are more biased, this method of hooking the marble to unlock the lock is a test of proficiency.

If a professional thief is caught stepping on a sewing machine and comes out after three to five years, his theoretical knowledge may be enriched and his strategic thinking more complete, but his hands will definitely grow, and he must practice for a period of time before he can recover.

As for the No. 30 people in the yard, will someone deliberately prepare technical reserves just for this moment?

Not impossible, but kind of stupid.

The lock used for Yuan Jiansheng's study door is excellent, and it is extremely difficult to unlock.

Faced with this kind of mechanical lock, even a very professional thief will need a period of time to open it. Moreover, it is often necessary to have an accomplice beside him for special lighting to operate it.

At the same time, it is very inconvenient to wear gloves when using the technique of hooking the marble to unlock the lock. Many thieves die at this step.

If Huang Qiangmin was placed in a similar position and wanted to unlock it, he would rather find a way to steal a key to Yuan Jiansheng's study.

Before that, Yuan Jiansheng's study keys were not strictly managed, and it was possible for acquaintances to get them.

From this point of view, since the door lock of the study room is opened with a hook, the probability of an acquaintance committing the crime becomes very small.

Imagine a company executive in his 40s or 50s, with a master lock picker, or with a trusted accomplice, squatting in front of the study, poking his butt, spending more than ten minutes, or even two or three 10 minutes , slowly open the lock.

No matter how you think, you look like a fool.

"So, is it really possible that the case is for seeking money?" Huang Qiangmin thought about the transcript just now, and felt pain in his hands.

"From the evidence collected so far, ordinary burglary is more likely to steal some documents while asking for money." Jiang Yuan replied.

In Huang Qiangmin's mind, the words and scenes that leaders at all levels told him once again emerged.

Dare to be blind?

Huang Qiangmin asked: "What evidence do you have now, and what evidence do you need?"

Jiang Yuan thought for a while and said:
"The safe door has been wiped down and is not open."

"There are condoms and semen spots in the trash can. There are cigarette butts. There are saliva and spit marks."

"The drawers and cabinets all showed signs of being pried open and turned over."

"There were a lot of fingerprints and palm prints, but it shouldn't be too much of a surprise. There were glove marks."

"The footprints are messy, and some documents have been trampled on. Judging from the footprints, they are two males, one of whom is about 1.6 meters tall and light in weight."

When Huang Qiangmin heard this, he understood it. Indeed, based on the evidence, this case really seemed to be committed by a stranger, not an acquaintance.

"Temporarily keep the case secret." Huang Qiangmin thought for a while and told the four of them.

Yuan Jiansheng is not a criminal policeman, and he will not look at problems from the perspective of a criminal policeman.

For Jianyuan Company, which was in the listing stage, Yuan Jiansheng was at the time when he was most suspicious. He would not believe it without hard evidence.

But for Huang Qiangmin, everything has to wait until the case is solved.
