"Team Fu, Yang Yuting is lying."

Qi Zhibin and Song Jin, who went to the University of Science and Technology to learn about the situation from Yang Yuting at nine o'clock, said as soon as they entered the door.

"How so?"

Two days before Yang Wenjing was killed, on August 9, Yang Wenjing's classmates said that she had gone to the school to find Yang Yuting. But Yang Yuting said that he came back on August 10 and did not see Yang Wenjing. ”

"What, have you found evidence that Yang Yuting had seen Yang Wenjing on August 9?"

"Team Fu, look," as he spoke, Song Jin took out a USB flash drive from his satchel and inserted it into the computer that Qi Zhibin had opened. Soon the screen showed two figures in an open window in the corner of the office building of the University of Science and Technology. Song Jin pointed and said: "This is the picture taken by the surveillance camera in front of the experimental building of the University of Science and Technology. Although it is far away from the office building, the camera can just shoot the window of Yang Yuting's office. This is it. ”

"Zoom in, zoom in."

Seeing that the two shadowy figures inside were a man and a woman, Fu Yuan urged Qi Zhibin, who was operating the computer, in a loud voice.

When the picture was enlarged and simply processed by Qi Zhibin by technical means, two of them could be identified, Yang Wenjing, who was thin and wearing a dress. Taller and wearing a white T-shirt is the polite Yang Yuting.

"Immediately send the video group of the technical department, keep the backup, and then carry out further technical processing."

"Yes."

Qi Zhibin stood up, took out the USB flash drive and turned around and left.

Song Jin then reported to Fu Yuan: "We arrived at Yang Yuting's office at nine o'clock on time, but he was discussing the so-called English grammar and pronunciation problems with several students. After waiting for a while, a few students saw the opportunity to leave, and then we began to ask him. As last time, still no valuable clues were found.

Leaving Yang Yuting's office, because the school has already opened, we plan to find a few Yang Wenjing's classmates to learn more about the situation. I didn't want to go outside the office building, but I accidentally found the surveillance video in front of the laboratory building diagonally opposite. ”

"Didn't pay attention when you went last time?"

"No, we were looking around a bit at the time. At that time, no cameras were found in front of the laboratory building. It wasn't until today that I saw it and went to retrieve the monitoring data that I learned from the administrator.

Because some lethal chemical reagents and many expensive laboratory utensils and instruments were stored in the school laboratory building, this monitoring device has been around for a long time. It's just that a few days ago, on August 12 to be precise, the on-duty administrator accidentally found that the camera was broken, so he removed it. It wasn't until after the start of school that I wrote a report to the office, bought a new camera, and reinstalled it the day before yesterday. ”

"So coincidentally?"

"yes, we think there might be something wrong with that, too. But after looking at the video materials of the day the camera was broken, I didn't find out how it was broken. However, the deadline for video materials is 4:34 p.m. on August 9, just after the two met. ”

"Where's the broken camera?"

"The administrator said that when he sent the report to the office, he deliberately showed it to them, and then threw it away. Although we went to the trash can that the administrator said, the garbage had already been taken away by the garbage truck. ”

"Okay. I immediately arranged for the people from the police station below to retrieve the video materials along the way from the University of Science and Technology to the Jinghua Community on the afternoon of August 9. See if you can find out. ”

Seeing that Fu Yuan had finished calling the police station below, Song Jin said to Fu Yuan: "Team Fu, I'm afraid this matter is not that simple. ”

"Huh? Let's talk about it. ”

"If the camera is vandalized, there is a fear that their actions will be recorded. But why not destroy the hard drive inside the surveillance system server and just smash the camera? ”

"Makes sense. With Yang Yuting's meticulousness, he should not make such a simple mistake as wanting to cover up. Fu Yuan looked at Song Jin, who was also thoughtful, and asked, "You can't be suspicious, someone is trying to remind someone in this way, such as us?" ”

"But if I think about it carefully, this suspicion is not valid, unless Yang Yuting does not know that such a camera exists. But is it possible? ”

Without waiting for the two of them to discuss a result, Rong Liang and Zhao Zengyuan, who were in charge of investigating Zheng Qianjun, came back.

"Team Fu, there is a harvest."

"Have you found the person who came into contact with Zheng Qianjun?"

"It's not certain yet, but it's a big doubt." Rong Liang said excitedly: "In yesterday's investigation, we thought about the question of whether Zheng Qianjun has a girlfriend. But after some inquiry, they all said that they didn't find any girls who were very close to Zheng Qianjun. Today, I unexpectedly found that not only there is, but the two have maintained a cohabitation relationship for half a year. ”

"Since it's a boyfriend and girlfriend relationship, why do you want to make it so mysterious?"

"That's the crux of the matter, Team Fu." Zhao Zengyuan added: "If I hadn't found Zheng Qianjun's sister and brother-in-law's family today, I'm afraid I wouldn't have found it." ”

"Don't Zheng Qianjun's parents know?"

"Yes. Zheng Qianjun usually doesn't go home to live, and he never takes any girls home. When he was not a bodyguard, he lived in the staff dormitory of the Roewe company. When he went out to work as a bodyguard, he lived in the accommodation provided by his employer. That's why he gives people the illusion that he almost never has a girlfriend who is very close to him.

According to Zheng Qianjun's sister, Zheng Qianjun had a girlfriend, and they only met each other through the introduction of Zheng Qianjun's brother-in-law. It's just that this matter has not been made public. The main reason is that Zheng Qianjun doesn't want his parents to know for the time being, and he says that he doesn't want to start a family for a while. So his sister and brother-in-law didn't reveal it to their parents.

And Zheng Qianjun is also more interesting, although he goes to his girlfriend's residence from time to time, he never spends the night there. Even if two people play until one or two o'clock in the morning, they will definitely return to their accommodation before dawn. ”

"Why?"

"Her girlfriend told us that Zheng Qianjun said that he had a habit of choosing a table, and he couldn't sleep two or three days before changing the bed."

"What else did his girlfriend say?"

said that just before Zheng Qianjun asked for leave, a middle-aged man once looked for him two or three times in succession. Every time, the two would drink until midnight, but every time Zheng Qianjun didn't let his girlfriend follow, so I didn't know what they were talking about. I just know that the middle-aged man, forty-five or sixteen years old, is not tall, his name is Mu Qixiong, a local. ”

"Have you checked Mu Qixiong?"

"Checked. Mu Qixiong is a businessman in the antiques business, and he hardly has a family. Now he's out and about, and no one knows where he is. Maybe call in the morning and say it's somewhere, and change places in the afternoon. I heard his wife say that the two just spoke on the phone yesterday and will not be back for about a week. ”

"So, then you two split the work. Zeng Yuan was responsible for retrieving Mu Qixiong's call records to see if he could find anything from them. And thoroughly investigate the situation of Zheng Qianjun's girlfriend. Fu Yuan looked at Rong Liang and Zhao Zengyuan and said, "Rong Liang went to investigate Wei Dongdong, starting with the people around her. Focus on someone younger than her and with a beard. ”
