He Jing was not discouraged after meeting Shi Binbin. She took people to the Construction Building, copied all the videos of KFC and the Chinese fast food restaurant, and ordered people to search for Shi Binbin in these videos. Then she came again
Go to the Public Security Network Video Monitoring Center and look for traces of Shi Binbin’s activities on March 18 through the video recordings of the monitoring center.
The old campus of Zhongjiang University has a school gate on Renmin Road. It is only ten minutes' walk from this gate to the Jianshe Building.
Through the video of the Internet Video Surveillance Center, it was found that Shi Binbin came out of the school at 5:55 in the afternoon on March 18 and walked in the direction of the construction building. Shi Binbin walked very slowly along the way, stopping from time to time to check his mobile phone.
If you keep tapping the screen with your finger, you should be contacting someone.
Since the surveillance cameras were installed far apart, it was not possible to fully capture the images of Shi Binbin's journey from the video. He must have stopped at a certain location for a long time on the way from Zhongjiang University to the Jianshe Building.
He did not enter the range of a camera in front of the Jianshe Building until 6:31. In other words, he walked from Zhongjiang University to the Jianshe Building for a total of 36 minutes.
The KFC restaurant video shows that Shi Binbin entered the store at 6:32, ordered a cup of coffee, and then sat at the window seat with his face facing the window most of the time until he left KFC at 7:24. This is close to
Shi Binbin's body barely moved for an hour.
"This is so abnormal." He Jing thought. No one would look out the window so intently. Even if he was thinking, he would change his sitting posture from time to time. Unless he had a very important task, he would be so focused.
He Jing continued to search for traces of Shi Binbin after he left the KFC restaurant. At 7:26, Shi Binbin once again entered the shooting range of the surveillance camera on the sidewalk. He did not walk in the direction of Zhongjiang University, but continued to walk away from the university.
According to the tracking of cameras along the way, this time he was traveling at a relatively normal speed, walking about one kilometer every 12 minutes. After walking along Renmin Road for half an hour, he disappeared from the surveillance area of the camera at 7:53 p.m.
Inside.
It's impossible for him to disappear out of thin air? He Jing thought. He either turned into a nearby alley or got in the car in an area that was not covered by the camera. In order to confirm his conjecture, He Jing returned to the entrance of Zhongjiang University.
That camera was looking for images of Shi Binbin when he returned to school.
Hard work paid off. When He Jing watched the video at the school gate at 10:45 pm, he saw Shi Binbin taking a taxi to the school gate, and after getting off the bus, Shi Binbin entered the school gate.
From 7:53 to 10:45, where did Shi Binbin go? Is it related to him stealing the mobile phone? He Jing began to doubt Xu Wen and his own judgment. Was he the one who stole the mobile phone? Yes.
Could it be that he just happened to go out at that time, and was there someone else who stole the phone?
He Jing had no choice but to dial Xu Wen's phone number.
"Hey, Xu Wen, are you confident in your judgment?"
"What's wrong, Captain He, don't you have confidence in your own judgment?" Xu Wen joked.
"Oh, there's no way. We went to the school to investigate, and we spent time checking all the videos along the way, investigating his whereabouts, but we didn't find any valuable clues."
"Have you checked his call records?"
"No, I have no reason to check his call records at the moment. I think it would be useless even if I checked. If he is really suspected, with his calm demeanor, he will never leave any clues on the phone.
"
"Well, what you said makes sense. Also, can you check his chat history on social software?"
"To check these records, we must get his mobile phone. We have no way to check the chat records from the server. The chat records are only saved on the mobile phones of both parties."
"Well, I know this."
"He is not suspected of breaking the law now. We can't just check someone's mobile phone."
"I understand, have you investigated his family and social background?"
"Not yet, do you think it will be useful?"
"I don't know. My intuition tells me that this young man is not simple. Maybe I can tell something from his family background and social relations."
"This should be simple. I'll arrange for someone to check it right away."
After hanging up He Jing's phone, Xu Wen thought of Hassan. Can Hassan use technical means to obtain clues that the police could not obtain through conventional methods? He sent such a message to Hassan through QQ.
Arrow: Blackhawk, can I get the chat information on my personal mobile phone?
A few minutes later, Black Eagle's profile picture flashed and a message was sent to Xu Wen.
Black Hawk: If you can get the phone, it's a very easy thing. Even if it's the information he has deleted, I can still reply. If you can't get the phone, there are two situations.
Flying Arrow: What two situations?
Black Hawk: If you don't mind turning someone else's phone into a brick, it's not that difficult. I can hack and hijack the phone at will and get all his data. But if you don't want the person to know that the data has been stolen, then
It's a bit troublesome.
Flying Arrow: The latter type.
Black Eagle: Okay, I knew it would be like this. Please send me your mobile phone number.
Fei Jian: That’s the young man wearing glasses, Shi Binbin, from last time.
Black Hawk: I understand. Which chat software do you need the records for?
Feijian: Let’s take a look at QQ first. Many numbers in this software are not real-name and can easily be exploited.
Black Hawk: Hahaha, just like us.
Fei Jian: Haha.
After interrupting the chat with Black Eagle, Xu Wen turned on the computer and took out the video of the KFC restaurant to watch. He turned the playback speed to the slowest and carefully observed Shi Binbin's every move.
He turned his head, scanned the restaurant, stood up, scanned the restaurant again, and left. These actions were all completed in 2-3 seconds, and no one at the scene would doubt him. But if you observe it from the slow-motion camera
, his every move is so accurate, in place and fast, basically comparable to a professional agent.
My judgment is definitely not wrong, Xu Wen thought. This young man must have received some kind of professional training, otherwise he would not be able to perform such high-quality movements. What does he do? Do you want Qian Fei to find out?
His background? Could he be someone from an organization? Thinking of this, Xu Wen dialed Qian Fei's phone number.
"What? Have you been enjoying your life recently?" Qian Fei's teasing voice came over.
"No way, I'm just sorry to trouble you."
"If you have anything to do, please tell me quickly. I'm busy here."
"I want to ask you to help check a person and see if he has any hidden information."
"You suspect...?"
"right."
"Okay, but if there really is a background, I can't tell you."
"It doesn't matter, I just want to know if there is or not."
A beeping busy tone came from the receiver of the phone. Qian Fei always did things neatly and neatly. Xu Wen smiled and shook his head and put away his phone.
