We found Han Xiaoman's best friend Li Tingting again and asked her if she knew about Han Xiaoman's black industry engaged in "original" operation.

The two are college roommates and best friends, and girls often share little secrets with each other.

"I'm not lying, I really haven't, I've told you everything I know!" In the face of our doubts, she kept waving her hand and shaking her head.

I came to Li Tingting again to ask her, but this time not in the police reception hall of the Public Security Bureau, but in the interrogation room.

"Do you really not know about Han Xiaoman's micro-business business?" I looked at Li Tingting's eyes seriously, and her eyes subconsciously avoided it.

Clearly, she was lying.

"Han Xiaoman's disappearance, you were the first to find out, we now have reason to suspect that you are involved in this case, if you don't cooperate with us, I can't help you." I raised my voice and spoke more firmly.

Li Meng also spoke at the right time: "Han Xiaoman is likely to be controlled by the buyer, you are best friends, you should know what will happen after a girl is controlled." ”

After listening to Li Meng, Li Tingting was so frightened that she shrunk into a ball like a kitten.

She looked at us in a daze, hesitated for a moment before speaking, "I...... I...... I didn't. ”

I stood up, pulled a chair in front of Li Tingting, sat down and asked her in a calm tone, "Do you know that Han Xiaoman is doing the 'original' business?" ”

Li Tingting nodded timidly, her eyes falling on her hands that were constantly buttoning her nails because of nervousness.

"How do you know? Did she pull you along with the 'original' business? I asked her softly.

She was silent for a while before replying, "She told me that she did ask me to join her, but I didn't agree." ”

Subsequently, she slowly said something about Han Xiaoman's micro-business business:

"We were roommates and good girlfriends in college. When he was a senior, Xiaoman was doing a micro-business, selling some clothes through the circle of friends, and the business has been doing so far. At that time, our classmates in the dormitory all helped her forward the circle of friends and helped her do publicity.

If you want your business to do well, you must expand publicity and increase the resource base, so Xiaoman used Shake to keep adding friends with people nearby, adding many people. Xiaoman is beautiful, there are many people who agree to the application of friends, and there are many people who add it, so naturally a lot of perverts are added, and she says all kinds of strange things to Xiaoman, she also sends me some screenshots to see, and complains to me a few words.

I comforted her, 'There are a hundred people, all sorts.' has been in business for a long time, and she can meet any kind of person, but she didn't take it to heart, and continued to add friends to expand the list after being blocked.

I knew that she had already graduated from college when she was in the 'original' business, and one night, she forwarded the perverted chat history to me as usual and complained. One of them said that he would pay a thousand yuan for a pair of socks that she worn, and we said at the time: I really don't understand why there is such a pervert.

A few days later I found out that Xiao Man had actually sold her socks to the pervert, and to my surprise, she had actually received a thousand dollars.

Since then, while doing micro-business business, she sold 'original flavors' through various social software, and after making money, she searched on the Internet to learn how to make them, and began to make so-called 'original flavors' in large quantities, and she also invited me to do it together, but I didn't agree...... I have advised her more than once that she must be careful of these perverts, and Xiaoman said that her transactions are non-face-to-face, and she will not expose any private information, which is very safe. Everyone has what they need, and it's not illegal, it's fine. ”

Li Tingting didn't continue to talk about this, I think her original intention was not to hide this matter from us, maybe she felt that this matter had nothing to do with the case. Once the police and Han Xiaoman's parents know, Han Xiaoman's image will be ruined, and he will have to bear the pressure of various public opinions.

Now the case has become more complicated, Han Xiaoman has been engaged in the business of selling 'original flavor' for a long time, and there are many buyers, although Han Xiaoman has always paid attention to protecting his privacy, but there is still a possibility of leakage. It is likely that she met a bad buyer and kidnapped and detained her.

Since Han Xiaoman's disappearance, the mobile phone has been turned off, and this case cannot be delayed any longer, and every second must be made.

In order to determine the identity of the murderer first, we had to start from two directions at the same time, on the one hand, to find Han Xiaoman's buyer, and on the other hand, to find near Han Xiaoman's place of residence according to Li Meng's criminal profile.

"Do you know what platform she sells on? How do you get in touch with buyers? "I continued to ask Li Tingting about Han Xiaoman's sales machinery.

Li Tingting's body trembled, and her eyes looked at me with some trepidation, and she now understands the seriousness of this matter: "It's all some social platforms, shake and drifting bottles and the like, she mentioned before that there are more buyers of this kind of software." The specific private chat should be a WeChat chat, I guess it should be so, Xiaoman didn't tell me. ”

We decided to start the investigation with Han Xiaoman's buyer, and the Serious Crime Team had the highest authority of the Ministry of Public Security when solving the criminal case, and we cracked Han Xiaoman's social software account password through the technical investigation department.

There are no less than 2,000 people in Han Xiaoman's social software friend list, and more than ninety percent of them have no notes, and the way to add them is to shake it and people nearby, it seems that as Li Tingting said, she added a lot of strangers in order to expand the list.

Through time inquiry, we found the last buyer before Han Xiaoman's disappearance, and the message record shows that the buyer first paid the deposit, and then Han Xiaoman told him the transaction location and locker password, and the buyer settled the balance after receiving the goods.

The buyer was suspected of committing a major crime, and the Serious Crime Unit immediately deployed an arrest operation.

At the same time, the professional police officers of the Technical Investigation Bureau completely imitated Han Xiaoman's usual chat habits, including the customary length of each message, punctuation marks, small emoticons and emojis.

And just like that, we quickly got in touch with this mystery buyer.

We chatted with him in the form of the seller's after-sales experience survey, and after a while, the other party suddenly became alert and did not reply to the message for a long time.

"Won't it be exposed? If he was really the murderer, he must have known that the person he was chatting with now was not Han Xiaoman. Li Meng looked at me with a sad face.

"If this is really the case, it will be easier to track directly through the mobile phone number bound to the other party's WeChat account." I frowned, staring at the computer screen, waiting for a reply.

After about five minutes, the other party finally replied......
