Because the thief was so exhausted, even though he was wearing a mask, a respirator and gloves, he still left behind a lot of evidence, and the traces of various instruments used were also very obvious.
After all, the surveillance here is still useful. Thieves are not shy at all and all they care about is speed.
Everyone agrees that a person who steals is an amateur among amateurs.
However, this also increases the difficulty of solving the case. There are only so many repeat offenders, and as for newbies... anyone could be one.
"The investigation team from the Municipal Bureau will be here in twenty minutes. The technical investigation, image investigation, network and other departments have also given the green light. We have to catch the criminal in this case before daybreak. We will let the Municipal Bureau and Director Yin hear the report at the morning meeting tomorrow. We can't leave it hanging." Director Ma looked at Captain Li with a calm expression.
Although Captain Li and Director Ma have some personal grudges, Captain Li also knows that Director Ma is not targeting him. Instead, he is to blame for not solving such a big case, with so many clues and so much manpower, within eight hours.
Normally leaders would not issue such an order to solve a case within a limited time, because it could easily backfire, but this case shouldn't be a big problem, and tomorrow morning is plenty of time.
From the on-site surveillance video, we can see that the thief wore protective clothing, used an oxygen respirator, used a sling, and used...
For some reason, when everyone was thinking about the thief's identity as an insider, Bai Song's mind kept showing a word - a chuunibyou patient.
If he didn't have the second-year syndrome, how could he do such a thing?
This person really thinks crime is too simple, a sentence of more than ten years is the starting point...
Director Ma went to the police station. He had a lot of work to do and needed an office to work in. The scene was completely handed over to Captain Li.
It was past ten in the evening, and many leaders had come to the case, including many leaders at the same level as Captain Li, but at this moment they all had to listen to Captain Li's command. This was not a good thing, Captain Li looked at his watch, his expression tense.
At 11 o'clock in the evening, the little girl who rented the house was found.
Upon questioning, it turned out that the little girl lived alone and was not at home today. The little girl had a very messy interpersonal relationship. When I got her phone, I found that there were more than a dozen "brothers" on WeChat, and there were countless people with whom she had close relationships.
But the girl’s circle of friends is very normal, just showing off food, beautiful pictures and various PS photos. As a result, many people flatter her, and some people even send her red envelopes.
There is nothing special about this situation. Upon questioning, it was found that the girl had never given the key to the house to anyone else and had not returned home today.
This obviously did not satisfy Captain Li. After several inquiries, the little girl rolled her eyes and talked nonsense. Anyway, she refused to cooperate. This really pissed Captain Li off. The girl looked only a little older than his child, and she was pretty. She was not a prostitute, but she was not a good person.
She can lie easily, no wonder she can deceive more than a dozen people on WeChat...
But she was still too naive. Who could be fooled? How could she get into the house when she was the only one with the key? After all, the possibility of unlocking the door with skills had been completely ruled out.
Therefore, Captain Li arranged for someone to record her cleverness and some lies. It was time for her to know the truth of this world! Regardless of whether the thief could be caught or not, based on the girl's non-cooperation and nonsense, it would be no problem to charge her with harboring a criminal!
Professional personnel from the Municipal Bureau conducted a thorough investigation and sampling of the scene upstairs and downstairs, and found a large amount of evidence at the scene.
First, a moderate amount of sulfate ions were found in the solution, which means that the purity of the hydrofluoric acid here is not high. The way to prepare hydrofluoric acid in large quantities in industry is to heat potassium hydrofluoride or fluorite mixed with sulfuric acid. The reaction conditions are very harsh and basically difficult to achieve at home. Regular factories will purify and distill hydrofluoric acid through multiple procedures, and there will basically be no sulfuric acid residue, and the sulfuric acid in this is obviously a residue.
This will lock out some low-quality factories.
The second is that rope fragments and manganese and chromium alloys were found in the solution, which was inconsistent with the situation of the steel bars in the reinforced concrete. This means that stainless steel pliers or brackets, pulleys, etc. were used and some of them were corroded.
Third, Bai Song also found that the tools used to remove the floor upstairs were professional and were also purchased online. Bai Song had participated in the installation of the floor before and was very concerned about this detail, so he easily obtained a new clue.
I have to say, helping Big Brother do good things before was still useful.
Although anonymous,...
The fourth to twentieth on-site evidence are omitted here...
The most important thing is that the amount of video surveillance data in this case is outrageous.
Everyone present generally believed that this case was most likely an inside job, because they knew the gold shop well enough. Although it was unlikely that the perpetrator was a clerk in the shop, it was very likely that he had experience working in a gold shop.
An hour later, the information of all male staff members of the gold shops nearby was placed in front of the members of Team 3. The sales staff of gold shops are mainly women, and there are not many people engaged in related work. Due to the standard suspect body shape model, it only took about half an hour to eliminate all the people in this information.
This surprised everyone. Wasn't it an inside job?
At this time, Wang Liang and others also came out with a video analysis report on young men who had visited the store many times. The order of the cabinets in this store changes every once in a while, mainly to give customers a sense of freshness every time they come. The last time these cabinets were changed was a week ago.
This is a very easy situation to analyze. Since he is not an internal staff member nearby, then someone must have come in recently to survey the terrain. Otherwise, how could it be so easy to find the cabinet where the bracelets are placed?
When this case first came up, there were only these two options.
Wang Liang and others also encountered some bottlenecks in their analysis of the video footage over the past week. For one thing, no person with a body shape similar to that of a thief had come in over the past week.
The second is that no one has ever paid much attention to the placement of the gold bracelets, the position of the lock, and the structure of the gold bracelet cabinet. Everyone seems to be only interested in shopping, and no one is abnormal.
A gold shop is not a vegetable market. Only a few hundred customers came to this shop in the past seven days. So many police officers analyzed these people several times but did not find any problems.
If this possibility is ruled out, then the crime can only be committed by an insider? Then, who could it be?
