Profiler 2: Criminal Investigation Brigade

The shipment volume of this e-commerce company is huge. One program can sell hundreds of tablet computers, and the cumulative sales have reached 10,000+ units.Although they have a list and contact information of all customers, but because of the large sales volume, there is no one-to-one correspondence with the mobile phone card numbers that come with each tablet computer.

Moreover, Shencheng's satellite TV is watched uniformly across the country, that is to say, the consumers of this trading company are all over the country.There are thousands of local customers in Shencheng. This investigation work can be said to be massive.This does not include the situation that consumers lend their mobile phone cards to others, or discard them at will, and someone picks them up.With this workload, I don't know how long they have to work, so it's no wonder that they are anxious.

The mobile phone card issued by his own trading company has actually become a criminal tool, and the user has become a criminal suspect.The sales manager Li Yadi was very frightened, and kept nodding his head and said: "It's a real name, indeed, it's already under the real name system, and it's all under our company name! This kind of card is called a business card or a fixed-line phone card. It's specially used for making business calls, and it doesn't violate the national laws." policy!"

Jiao Yang said unhappily: "Then it's so simple and rude for you to serve customers and run a company? Just take a card and stuff it in. What a hidden danger of crime is this? Whatever people do in the future will be your company." You are blamed! Be careful, in the future, you will have one-to-one correspondence between cards and machines, and register them before selling them. Don’t just think about making money, as an enterprise, you should also take some social responsibilities!"

"Yes, yes, yes!" Li Yadi nodded his head like a chicken pecking at rice, and said repeatedly: "Officer, you are right, we will rectify immediately, and we must learn from experience and lessons, so as not to cause trouble to the society!"

Jiao Yang returned to the team with a bunch of sales information, "Brothers who have nothing to say, let's analyze it first and focus on the direction of investigation!"

Yu Xiaoguang said: "Since all the incidents are in the surrounding area, let's investigate first, the customers in the city!"

Hou Xiyong added: "Then, according to the age range of suspects defined by Professor Lu, these young male clients are first picked out..."

Mo Ke said: "On this customer list, there are only mobile phone numbers and addresses, and no ID information. How to distinguish between men and women, as well as age?"

Jiao Yang sighed and said: "Yes, it is possible. According to the mobile phones they have left, go to the operator to get the identity information! Now that the whole country is connected to the Internet, the mobile phones must have real names. They can't all belong to some trading company. Landline card, business card?!"

Hou Xiyong went to the three operators, obtained the account opening information of these phone owners, and then screened out three to 400 people according to the suspect profile that Lu Yuanli had set.

Although it can be regarded as progress, Jiao Yang looked at the roster of 400 people and didn't know what to think.Even with such a large investigation area, there is no guarantee that the suspect is inside.After all, the domestic population flow is so large now.Whether that person is a native of Shencheng, or whether he lives in Shencheng, is not sure at all.

However, if you check the total sales list of 10,000+ people, the suspects may be in the tens of thousands!There are only a few foreign guns in their team, there is really no way.You can check this range first, and if you don't find it, expand it slowly.

Unexpectedly, after some in-depth reviews and internal investigations, it really achieved results.Li Yadi, the sales manager of Yihe Trading, happily came to the police station to provide clues.

Li Yadi held Jiao Yang's hand and said, "Captain Jiao, we have discovered a particularly important situation, and hope it can help us solve the case!"

Jiao Yang nodded and said, "Okay, thank you very much, Manager Li, for coming to the police force to provide information! What did you find, please tell me in detail."

Li Yadi said: "Captain Jiao, although our mobile phone cards do not correspond to tablet computers one by one, we have a total sales record."

Isn't that still a total of 10,000+ numbers and consumers?For a moment, Jiao Yang didn't understand what Manager Li wanted to express.

Seeing that he didn't seem to understand, Li Yadi continued to explain: "It's these mobile phone cards. Although there is no one-to-one binding with the tablet, we have the identification code records of the mobile card. That is to say, he can In batches. Batches of mobile phone cards are sold out as a whole following the identification code of the tablet computer. About a few thousand units are sold for each program. The time of sale and the time of delivery to customers can be checked. to the record."

When Jiao Yang heard this, he became energetic.That is to say, each sale is at most a few thousand units, and the mobile phone identification number is among them. Then, from the addresses of local customers in Shanghai screened out in the past few days, young male suspects who meet Lu Yuanli's delineated range are found.It should also be possible to greatly narrow the encirclement, and cross-screening, the accuracy will be higher.

Unexpectedly, Li Yadi went on to say: "We found the identification number of this mobile phone card, compared it with the sales record, and found that it was not there. That is to say, this card has not been sold from our company, and it should still be sold. It was in the inventory. Then, I took the staff and checked the inventory again. You think it’s strange, this card is gone. At the same time, there are more than ten cards lost, and the identification codes are checked one by one. I can't find any of them!"

Jiao Yang's heart suddenly turned cold, doesn't that mean he didn't say anything?And it's probably worse than saying nothing!

Sure enough, Li Yadi went on to say: "Maybe this card is still not available from the operator..."

Oh my god!Jiao Yang's eyes went dark, he was still in the communication company, this is no longer a matter of finding a needle in a haystack, it is about finding a spot of light in the Milky Way!

"Wait a moment."

Lu Yuanli walked out, looked at Manager Li and said, "The clue you provided is indeed very important. You should immediately contact the supplier you are connected with to confirm whether these cards have been shipped. Then provide your company , all the information of the incumbents within one year."

Li Yadi looked at him in surprise and said, "You, who are you? Are you suspicious of our company's employees?!"

Lu Yuanli said calmly: "As far as I know, the value of this kind of mobile phone card is not high, and the major operators give it to consumers as gifts. These dozens of cards are worth 200 to [-] yuan." Let’s pay. Then why does the operator charge you these dozens of cards?

It depends on the meticulous management of your company, a large number of mobile phone cards do not correspond to mobile phones.Tablet PC management may be better, but for this kind of mobile phone card, I'm afraid it's just random.I'm afraid you don't know if there are any employees of the company who took two cards and used them for themselves, or outsiders took a few cards and left. "

"This..." The situation was provided to my own people!Li Yadi's forehead was covered with sweat, "Our employees do use this kind of mobile phone card, but they need to apply for it, and they need to register for whatever mobile phone number they use...

Lu Yuanli said, "So, are you sure you didn't misuse it?"
