The cold is almost better, and Li Jing and I have officially entered the process of investigating the case. Because I was sick, the meat dish for lunch was only boiled chicken breast, so I poked the chicken breast in the lunch box and asked Li Jing: "Li Jing, in fact, there is one easiest way to catch the thief." ”

"What way." Li Jing's meals for a few days were the same as mine, and he seemed to be afraid that I would be sad to see him eat big fish and meat, so he ate very lightly with me.

"Arrange security. Wouldn't it be nice to arrange two security guards to take turns on duty on the 3rd floor every night? Then, as soon as you hear a movement, you just go and arrest someone. What a hassle! "I continued to poke the chicken breast in the box.

"Do you think the people in the office building didn't think of it? First of all, there is the issue of cost, you have no idea when the thief will patronize, so the long-term labor cost of adding two more security guards is not something that every company is willing to increase. Also, there was a company that did add security personnel, but it was stolen in the end. ”

"Huh? It's too backy. I sighed.

"There are also the 3rd floor surveillance of these stolen office buildings, which failed on the day of the theft, and by the time the security guards reacted and went to the 3rd floor to check, the thieves had long since disappeared." Li Jing added.

"Does he only steal laptops every time?" I thought for a moment and asked.

"yes, the only thing you have in the office is a notebook, right? Others, such as safes or something, are not very convenient to transport, so they are not touched. Q: What does this do? ”

"No, I just think that this thief is so tough, and he will destroy the surveillance, and his skills are extraordinary, just stealing the notebook is really condescending." I complained.

Li Jing patted my head: "What are you thinking? Can you put the three views in the right place? ”

"I'm just talking! If I really support him that much, I would never recommend you to Team Xiao to arrest him. Besides, I mean, why doesn't he work hard and contribute to this society if he has such good skills! "I rubbed the area where he had been patting.

"That's what you can say." Li Jing glanced at me, "But it is still uncertain whether it was an individual or a gang." As you said, this case involves three aspects: technical control, counter-reconnaissance, and enforcement, and although it cannot be said that it is unrealistic for one person to do it, it is more likely that the gang will commit the crime. ”

"So many people for a few computers? Used computers aren't worth a lot of money, are they? "I don't understand.

"This is also my strange place, if you look at the results of their crimes, they do not conform to the characteristics of gang crimes; But if you look at the amount of work they do, the possibility of committing a crime alone is not too great. Li Jing fell into deep thought.

We finished lunch silently, and when the market was closed, Li Jing suddenly spoke: "Xiaozhi, when it's okay, help me go and see which companies are renting the 3rd floor of the stolen office buildings." I've always felt that the suspect didn't just commit the crime for a few computers. ”

There was still some time left in the lunch break, and there was no one in the supermarket to buy anything, so I simply checked the information on the location of each theft based on the information I had taken from the place where I was a child. I remember that when Shi Hao's brother didn't call back to get information, he would do horizontal and vertical comparisons, so this time, in the absence of technical support, I also hope to be able to provide Li Jing with this method.

So far, there are five office buildings that can be linked to the 'office theft', the earliest one occurred in March this year, and the last one happened just a week ago. In ten months, an average of one case occurs every other month, and there is still an obvious time pattern.

However, no obvious pattern has been found in the location of the theft, sometimes in different areas, sometimes in the same area. Similarly, I didn't find any particular preference for the type of office buildings that the suspect was targeting, which were very ordinary commercial office buildings. The brand of the stolen item, I looked at the stolen item records and found that the suspect seemed to have a special preference for T-brand notebooks, and almost all of the notebooks that were found would have one or several T-brand notebooks. I opened a trading website in the same city, entered most of the stolen notebook models, and found that there was no seller in the store pù similar notebook transactions, could it be that the suspect was afraid of being traced, so he dismantled the notebook and sold the parts? If this were the case, it would be even harder to find out than it is now.

I was distressed for a moment and thought it would be better to start with the tenant information in these stolen office buildings and see if I could find overlapping information. It took an afternoon, door-to-door search information, and even the legal person of the tenant was found out, but there was still no overlapping tenant information, and the only thing that can eat the overlap is that there are several overlapping companies' business types, these companies are the headquarters of some offline electronic product sales agency companies, but there is no record of theft of these companies.

At dinner in the evening, I told Li Jing about the afternoon's harvest, and Li Jing helped me scoop out the corn in the vegetable soup, so that I could discuss it with him when I was full.

While I was washing the dishes, Li Jingwo was on the sofa and looked back and forth through the information of several office buildings I had sorted out. I wiped my hands and came out of the kitchen, sat on the sofa and read the information with him, but I have studied these materials for an afternoon and have not found any other reasons, so I can only put down the information and observe Li Jinglai, if Li Jing keeps looking at the information carefully, he is really a quiet beautiful man, just do this quiet beautiful man, don't be a conceited poisonous tongue youth, I slandered in my heart.

"What do you say bad things about me in your heart?" After suddenly turning his head and asking me, I was startled.

"No, how dare you say bad things about adults?" I dogged off his claims.

"Just by looking at your expression, you know that you didn't say nice things about me. Let's not talk about this for a while, this time the summary has improved, and I know that I have to sort it out before handing in my homework. Li Jing praised me, "But I still haven't sorted out the core information of the case." "After complimenting me, I was so annoying.

"It's worth noting that the suspect has a preference for a certain object, but if you dig deeper, you can focus on the structure of the third-floor tenant of the first office building, and you will find that the suspect still has his own unique preferences." Li Jing pointed to the information of the first office building, "You see, the three floors of the first office building were leased by five large companies, and these five companies also have offices on other floors, but there is no overlap, but these five companies have a convergence on the third floor, which means that the third floor belongs to the headquarters of these five companies." This didn't happen on any other level, and of all the cases, the first case of the Constitution was always of paramount importance to the Constitution, and may have been the source of his initial crime, and the success of this place gave him the most sense of accomplishment and confidence to support his later crimes. Therefore, researching the first location of the crime is very important for our next investigation. ”
