heart poison

Hua Chong pretended not to notice Meng Xiaoqin's gaffe, and smiled relaxedly, "By the way, do you usually have any hobbies?"

"Hobbies?" Probably unexpectedly, Hua Chong changed the subject suddenly, and Meng Xiaoqin's eyes were a little dazed.

"Girls have some hobbies more or less, shopping, collecting beautiful gadgets and so on."

Meng Xiaoqin's eyes darkened slightly, and she smiled wryly: "I'm too busy at work, I just want to sleep when I go home, and I don't have the energy to think about other things."

"That's true." Hua Chong praised: "Work hard while you are young. Your salary as a five-star hotel manager is high, and you can buy a house after a few years of work. Oh, I remembered it when I talked about it. When do you plan to move out?" What about Daoqiao Road?"

"This..." Meng Xiaoqin was slightly displeased, "Mr. Hua, this has nothing to do with the case, right?"

"Of course not. I've already understood what I should know, and I just chatted a few words just now. In this society, isn't everyone most concerned about houses, cars, tickets and houses." Hua Chong said with a smile: "It's okay if it's not convenient to answer private matters."

Meng Xiaoqin tightened her fingers and looked away, "Our family has no plans to buy a house yet."

"That's it." Hua Chong got up and looked at his watch, "Sorry, I'm offended. It seems that the time is almost up, you have to start work in the afternoon, right?"

Meng Xiaoqin also stood up, the corners of her lips were raised, but the sadness between her brows did not disappear immediately, and she smiled formulaically: "If you need me to do anything in the future, just contact me."

On the way back to the Municipal Bureau, Hua Chong was driving very slowly while sorting out Meng Xiaoqin's reaction just now.

When approaching the Municipal Bureau, the phone rang suddenly, and the words "Liu Zhiqin" flashed on the screen.

He picked it up, "What?"

"Flower team, where are you? When will you be back?"

"I'll be there soon, what happened, the tone is so urgent."

Liu Zhiqin said: "I found the person who sent Tang Su a postcard from Beiman Mountain."

"Is this the Weibo of 'a celery'?" Hua Chong hurried back to the Municipal Bureau, walking too fast on the road, sweating a little, and had already taken off his coat at this time, and the sleeves of his shirt were rolled up to his elbows.

On the display screen, there is a user homepage with an all-black profile picture and the name "hqudyxkfmkaidhe". The number of followers, followers, and posts are all displayed as zero, and the background is the initial default background, and no data can be seen.

"How did you find this Weibo?" Hua Chong asked.

"Tang Su often uses the laptop in her study to access this homepage, and the traces on it are easy to extract." Liu Zhiqin typed a few times on the keyboard, and a string of codes flashed on the display screen, "Once a week on average, Just take a look, do not leave a message, do not send a private message, the last visit was December 12 last year. h—let’s call this user h—the registration time was 31 years ago, and the event of clearing Weibo happened 7 years ago."

"4 years ago? When exactly?" Hua Chong became vigilant. The Beimangshan postcard of "a celery" was sent to Tang Su 4 years ago, and Tang Su's current Weibo was registered on 4 12 years ago. moon.

"It was completely emptied on September 9. However, many followers and Weibo have been deleted one after another before. But even if it is deleted in the background, the traces of the Internet cannot be completely erased. I cannot restore it on a large scale for the time being, but after the deleted In the private message, I found a receiving address sent by a user. Look, this is the one."

"Building 9, Block C, Qishanju, Mingluo District, Luocheng City, Han Province. Isn't this Tang Su's home?"

"Yes, combined with other conversations in the private message, I can confirm that this user named 'Sea Tide Sudden Passing' is what we have been looking for, Tang Su's previous Weibo account." Liu Zhiqin said: "This message containing the address The private message was sent on May 4, 5 years ago, and the postmark on the postcard was on May 19. So this must have been sent by Tang Su when h asked who needed the postcard on Weibo."

Hua Chong pondered for a few seconds, "I'll check the homepage of 'The Tide Gone Suddenly'."

"Here." Liu Zhiqin tapped the keyboard, "I've already checked it out, she posted a lot on Weibo, the last post was on December 4, 12 years ago, and 2 days later, she registered a new Weibo account. Number."

"Why do you want to change your account?" Hua Chong took two steps, "h cleared Weibo in September, and Tang Su registered a new account in December. Is there any connection between this?"

"Maybe just forgot the username and password. She said in a comment on the new account that she used to have an account and was always automatically logged in. Later, she changed the device and couldn't log in. It was not implemented 4 years ago. Real-name system, if you just forget the password, if you also forget the registered email address, it’s really hard to get it back.”

Hua Chong went back to the table and put one hand on the edge of the table, "There is no real name system, so there is no way to determine the identity of this h in reality."

"It is true, but I have already locked the login ip of 'his' back then."

Hua Chong's eyes lit up, "Where is it?"

"It's in Luocheng." Liu Zhiqin smiled, "To be more specific, it's on Daoqiao Road, Fukang District, Luocheng City."

"Flower team, the manufacturer who made this postcard has been found!" Li Xun hurriedly ran from the trace inspection department, and nearly collided with Zhang Mao when he entered the door.

"Slow down, Brother Xun." Zhang Mao gave him a hand, "I'm so happy, have you won the lottery?"

"Go, go! Where's the flower team?" Li Xun was impatient.

"Talking with Brother Xiaoliu in the conference room next door..."

Li Xun ran away, slamming on the door of the meeting room with "bang bang bang", extremely excited, "Flower team! Flower team! Flower..."

The door was opened from the inside, and Hua Chong was standing by the door, also very excited. What Liu Zhiqin found just now gave him a reassurance—the Internet is the right way to go!

"Flower team, look!" Li Xun stuffed the report into Hua Chong's arms, "The manufacturer of postcards has been found! It's this one! 'A Celery' didn't look for a custom seller online, she found it locally. small workshop!"

Hua Chong read the report very carefully.Trace identification is a boring but interesting and indispensable technology. A professional trace inspector can determine the machine from which a postcard is made through the paper, ink, cutting and other details, find the manufacturer that made the machine, and then Find the next home in the sales record, and finally lock in which printing studio.

Turning to the last page of the report, Hua Chong's hand stopped, and the light in his eyes shrank, "This photo is..."

"It was provided by the studio that printed this postcard! Is the person in the photo the same woman we met in Dongli Lane that day?"

Hearing this, Liu Zhiqin also rushed over.

The photo was printed by fax, so it is not very clear, but it is enough to judge that it is Meng Xiaoqin himself.

Hua Chong was both excited and puzzled, "How could she take such a photo?"

In the photo, Meng Xiaoqin looks younger than she is now. She is dressed in outdoor attire, with short hair and no make-up. She purses her lips and smiles at the camera. The joy in her eyes cannot be concealed.She held a dozen or so printed postcards like a fan, and stood beside three young people who were smiling happily.

"They are the owners of this small workshop, college students who have just graduated, and history lovers." Li Xun said: "Four years ago, they took a fancy to the tourism potential of Beimang Mountain, and they partnered to open a business in Toushan Town at the foot of Beimang Mountain. I opened a small shop similar to a slow post office, which sells homemade souvenirs, drinks, and also accepts customization. This person said..."

Li Xun pointed to the first man on the left in the photo, "He said that she was one of the first customers to visit their store, so on the day of picking up the goods, everyone took a photo with the postcard."

"But why didn't she send a postcard from this store?" Liu Zhiqin asked: "If it was sent from this store, the postcard should have the address of this store."

"I'm not sure about that," Li Xun said.

"It's easy to understand. She is eager to send these postcards. Toushan Town is remote, and it will take more time to send them from this store." Hua Chong said: "After finishing the postcards, her vacation is almost over and she has to go back. work, so I took the postcard with me and took the bus to Zheng City, posted the postcard there, and finally returned to Los Angeles by plane or train.”

"However, there are still many things I can't figure out." Li Xun focused on trace detection technology, and did not have a deep understanding of the case itself. "Does this postcard have anything to do with the deaths of Xu Yujiao and Tang Su? The woman in the photo Why did you send a postcard to Tang Su? Even if you send a postcard, it can't explain anything, right?"

"It's a big deal." Hua Chong laughed lightly, and patted Li Xun's shoulder, "Did you stay up all night? Your eyes look like you've been crying, so hurry up and take a rest. This time, your trace inspection department helped a lot."

Li Xun breathed a sigh of relief, and once he regained his energy, no matter whether he stayed up late or not, his eyes looked bright even if he had cried, "Why don't you rest, the case has not been solved. I'll go back and stand by, call me anytime you need anything."

As soon as Li Xun left, Hua Chong immediately called the serious crime team members who were still in the Municipal Bureau to the conference room, and asked Qu Zhi to invite Meng Xiaoqin to the BXF Hotel.

Qu Zhi really didn't expect Meng Xiaoqin to be related to the case, but the postcard Hua Chong found, the IP address locked by Liu Zhiqin, and the printed information verified by the trace inspection department have proved that the relationship between Meng Xiaoqin and Tang Su is extraordinary.

"I already chatted with Meng Xiaoqin at noon, but at that time I didn't have any evidence that she knew Tang Su or Xu Yujiao." Hua Chong held a pen, writing and drawing in his notebook as he said, "Some of her reactions were not great. normal."

Liu Zhiqin understood: "She is very calm, doesn't seem nervous at all?"

"Yes. She's too calm." Hua Chong said: "I'm a serious criminal police officer. I went to her place of work to ask her about the case. Although I was wearing plain clothes, it shouldn't make her feel any pressure. Right? Ordinary people should have some psychological fluctuations in the face of criminal police, but she doesn't have a very business-like attitude, which is not normal."

"I heard that the last time you went to her house to collect evidence, she urged you to find the murderer as soon as possible?" Liu Zhiqin asked.

Hua Chong raised his eyes, knowing that the other party wanted to go with him again, "In addition, today, she has emphasized twice that 'she is very busy with work and often comes home very late, worrying that she will also be killed by the murderer'. This is very deliberate, giving people a feeling of being actively on the side of the victim. And she said that she was very nervous, which I did not see. It is like a person saying that he is working hard, but 'hard work' just stays in words."

"Did you all see this?" Zhang Mao was surprised. "I was there when I went to collect the physical evidence. Why didn't I notice so much?"

"At that time, the clues were scattered, and no one would suspect Meng Xiaoqin." Hua Chong said: "I sorted out the clues later, and gradually realized that her reaction was irrational."

"Me too." Liu Zhiqin said softly.

"Besides, I mentioned to her that the murderer hid some physical evidence in the cracks in the bricks of her house, and told her two possibilities—the murderer was random, and the murderer was intentional." Hua Chong continued: "She can actually think rationally." Analyzed with me, and came to the conclusion that 'the murderer randomly chose to hide evidence in her home'."

"She might not notice it herself, the logic here is out of order." Liu Zhiqin said.
