Because the toss was so bad, although the thief was also masked, put on a ventilator, and wore gloves, he still left a lot of evidence, and the traces of various instruments used were also very obvious.

After all, the monitoring here is still easy to use, and the thief does not shy away from it at all, and pays attention to a fast word.

The person who steals is the layman of the layman, this is the consensus of everyone.

However, this also increases the difficulty of solving the case, there are so many repeat offenders, and novices... Anyone is possible.

"Twenty minutes later, the investigation team of the city bureau came over, and the technical investigation, graphic investigation, network and other departments also gave the green light throughout the whole process. Director Ma looked at Captain Li with a calm expression.

Although Team Li and Director Ma have a little personal grudge, Team Li also knows that Director Ma is not targeting him, but alarming such a big case, so many clues, so much strength, and he can't solve the case within eight hours, and he is indeed to blame.

Generally, leaders would not give such an order to solve the case within a limited time, because it is easy to backfire, but this case should not be a big problem, and it will be given until tomorrow morning, which is already plenty of time.

From the surveillance video of the scene, it can be seen that the thief was wearing protective clothing, using oxygen respirators, using slings, and using...

I don't know why, when everyone is thinking about the identity of the thief and committing a crime for an insider, Bai Song's mind always presents one word - a patient with the second disease.

If there was no secondary disease, how could such a thing be done?

This person really thinks about the crime too simply, and the sentence of more than ten years is the beginning...

Director Ma went to the police station, he had a lot of work and needed an office, and the scene was completely handed over to Captain Li.

At ten o'clock in the evening, there were already many leaders in this case, and there were also many leaders at the same level as Team Li, but at this moment, they all had to listen to Team Li's command. This is not a good thing, Team Li looked at the watch, and his expression was tense all the time.

At eleven o'clock in the evening, the little girl who rented the house was found.

Upon inquiry, the little girl actually lived alone and was not at home today. The little girl's interpersonal relationship is very chaotic, and when she gets her mobile phone, there are more than a dozen "brothers" on WeChat alone, and there are countless intimate relationships with her.

But the little girl's circle of friends is very normal, that is, showing off food, beautiful pictures and various PS photos, so many people lick her, and some people send her red envelopes.

There is nothing special about this situation, and upon inquiry, the little girl who has not given the key to this house has not been given to anyone else, and she has not returned home today.

Obviously, there was no way to satisfy Team Li, and after several inquiries, the little girl's eyes rolled wildly, and she talked nonsense, but she just didn't cooperate anyway. This really made Team Li angry, this girl looks a little older than his child, she looks good, and she is not in the leather and meat business, but she is really not a good person.

If you can deceive people, you can open your mouth to say, no wonder more than a dozen people on WeChat who can deceive people circle around her...

However, she was still too naïve, who was there to deceive? Under the premise that she only had a key, how could she enter this house? After all, the possibility of technical unlocking had been completely ruled out.

Therefore, her cleverness and some lies, Team Li arranged for someone to write them down, and it was time for her to know the truth of this world! Whether the thief was caught or not, it was no problem to convict her of covering up because of this girl's non-cooperation and nonsense!

The professionals of the city bureau conducted a thorough investigation and sampling of the upstairs and downstairs scenes, and there was a lot of evidence on the scene.

The first is that the right amount of sulfate ions is found in the solution, which means that the purity of hydrofluoric acid here is not high. The way to prepare hydrofluoric acid in large quantities in industry is to heat potassium hydrofluoride or use fluorite mixed sulfuric acid to heat, and the reaction conditions are very harsh, which is basically difficult to achieve at home. Regular factories will purify hydrofluoric acid, distill and other procedures, basically there will be no sulfuric acid residue, and the sulfuric acid in this is obviously a residue.

This will lock down some low-quality factories.

The second is that the debris of the rope and the manganese and chromium alloys found in the solution do not match the steel bars in the reinforced concrete, which means that the pliers or brackets and pulleys made of stainless steel are used, and some of them are corroded.

Thirdly, Bai Song also found that the tools for opening the floor upstairs were professional and purchased online. Bai Song, who had been involved in the installation of flooring, was very concerned about this detail and easily obtained a new clue.

I have to say that it was still useful to help Big Brother do good things before,

Although they are all anonymous, but...

Evidence at the scene is omitted here...

The most important thing is that the video surveillance data in this case is outrageous.

Everyone present generally believed that it was highly likely that this case was committed by an insider, because the level of understanding of this gold shop was indeed high enough, although it was unlikely that it was an employee of the store, but it was likely to be someone with work experience in a gold store.

An hour later, information about all the male staff of the nearby gold shop was put in front of the members of the third team. The sales staff of the gold store are mainly women, and there are not many people engaged in related work, because there is a standard model of the suspect's body shape, that is, about half an hour, all the people in this information are excluded.

This surprised everyone, wasn't it an insider?

At this time, Wang Liang and others also came out with a video analysis report on the young men who came to the store many times. The order of the cabinets in this store changes every once in a while, mainly to make customers feel fresh every time they come. The last time these cabinets were converted was a week ago.

This is a situation that is easy to analyze, since it is not a nearby internal staff, then someone must have recently come in to survey the terrain, otherwise how can it be so easy to find a cabinet for the bracelet?

As soon as this case came up, there were only two options.

And Wang Liang and others' analysis of the video of more than a week is also a bit of a bottleneck, for a week, no person with a similar body shape to a thief has ever entered, which is one of them.

The second is that no one has ever observed too much about the placement of the gold bracelet, the position of the lock, and the structure of the gold bracelet cabinet, and everyone seems to be only interested in shopping, and there is no abnormality.

The gold shop is not a vegetable market, and only a few hundred customers have been here in this store in the past seven days, and so many police officers have analyzed these people several times, and they have not found any problems.

If this possibility is ruled out, then it can only be an insider? So, who will it be?
