Three o'clock in the morning, Shangqiao Road, Wanwang Hotel.
Chen Shu and Zhu Chaoran, who were wearing police uniforms, entered the hotel and walked straight to the front desk. If nothing else happened, the waiter should be laying on the floor under the front desk like Xiao Wang, the police officer who picked up the hotel.
It's not easy.
"Dong dong dong!"
Chen Shu lightly tapped the desk at the front desk a few times.
A young woman lying under the front desk opened her lazy eyes, scratched her messy hair, stretched, yawned, and sat up from the cot.
She wiped her eyes and said, "The room is full today. There is no room left."
Chen Shu coughed twice: "I am a police officer from the Zhongshan Institute, come here to check the surveillance."
The woman who had been in the hotel for a long time was not surprised. She just raised her head and opened her eyes slightly and said, "Oh, okay."
She walked out of the front desk, led a few people to a small room next door, pointed to a computer on the table: "Password 123456."
After saying that, he shuffled towards the front desk, showing no interest in the police investigation. I don't know if he had seen too much or if he just wanted to go back and sleep again.
Chen Shu also sat in front of the computer in a familiar manner, opened the main control computer of the surveillance video, and started checking the surveillance according to the time provided by Liu Wanying.
Liu Wanying was already a little drunk when the incident happened and couldn't remember the exact time, so Chen Shu could only start from the time she checked in, select the elevator monitor, and turn on the multiples to scroll through it.
Zhu Chaoran squatted aside and watched for a long time with a frown on his face. However, he was so active by nature that he couldn't bear the loneliness, so he found an excuse and slipped out of the small room.
The two most basic work skills for police officers to handle cases are checking call sheets and monitoring surveillance.
Some technologies or techniques will be used in the surveillance process, but these can only partially reduce the scope. In the final analysis, we still need to use human eyes to see. If one person can’t see it, then a few more people will see it. If you can’t see it once, then see it a few times.
.
Viewing a video is not like watching a movie. You can skip and watch. Some cases are complicated, and you may even have to slow down and watch carefully frame by frame, with your eyes wide open.
For a three-hour case-related surveillance, if you are unlucky, it may take the police six hours to investigate. Moreover, surveillance is multi-faceted and multi-angle. If a single case occurs, it may be necessary to check all nearby cameras. This takes a long time.
It also doubles directly.
The workload is huge.
Therefore, larger police stations will have a video investigation squadron that is responsible for reviewing videos and is responsible for cooperating with the public security police to crack down on illegal activities and criminal activities.
This case was relatively simple. It only happened in the elevator, so Chen Shu just had to wait.
Half an hour later, a woman with nothing but a white bath towel appeared in the video. She entered from the sixth floor and walked out from the second floor.
When taking notes at that time, Chen Shu was a little curious, how could any woman dare to run around in public wearing only a bathrobe.
He wiped his nose and continued watching.
Another half hour later, a middle-aged man walked into the elevator from the first floor. When the elevator reached the second floor, Liu Wanying walked into the elevator still wrapped in a white bath towel.
Chen Shu was not interested in what Liu Wanying was doing on the second floor for half an hour. He moved his buttocks and sat upright, knowing that the main show was coming.
In the video, when Liu Wanying first entered the elevator, she nodded towards the middle-aged man and smiled.
The two also chatted face to face for a while. This surveillance could only record videos, not audio recordings. Chen Shu didn't know what they said, and could only judge their emotional fluctuations through the pictures.
The two seemed to be having a friendly exchange.
Liu Wanying's movements are actually a bit charming?
The elevator stopped at the fifth floor after a while. Liu Wanying's room was on the sixth floor. This middle-aged man must have had a room on the fifth floor.
The man walked between the elevator and the corridor and blocked the elevator door to prevent it from closing. Then he turned around and waved to Liu Wanying frequently. Liu Wanying waved her hand in refusal, but she still had a smile on her face.
After a short stalemate, the man rushed to Liu Wanying's side, grabbed her neck with one hand, hugged her waist with the other, and pulled her out of the elevator.
Within four or five seconds, the two figures disappeared from the surveillance video. The elevator door slowly closed, and there was no one inside.
During this process, Chen Shu saw that Liu Wanying was clearly holding on to the elevator door to resist being pulled by the middle-aged man when she was being dragged away.
He paused the video and watched the last moment when Liu Wanying was pulled out of the elevator, holding the elevator door tightly with both hands, and he made a decision in his heart.
He called up the surveillance camera in the corridor on the fifth floor of the hotel, watched it for another half an hour, identified the room where the middle-aged man was staying, took a photo and saved it in his mobile phone.
Chen Shu took out his work USB flash drive and copied all the surveillance video of the hotel last night, including the elevator, each floor, the lobby, etc.
When he walked out of the small room, he saw Zhu Chaoran's huge body lying on the front desk of the hotel, poking his head into the front desk.
Chen Shu walked forward with light steps, and the conversation between the two naturally came to his ears.
"Fat man, let me tell you."
Fatty? It’s only been a while, but you’ve already become so familiar?
Chen Shu was surprised by Zhu Chaoran's ability to attract girls, and had a vague idea of promoting it. For example, the female bartender in the bar, the female network administrator in the Internet cafe, and the female front desk in the hotel. These are all sources of naked social information. The case was solved
the beginning of.
"Being a front desk clerk also requires skills. If someone comes in to book a room in the middle of the night, I always only sell the most expensive suite, and the others are all said to have no rooms. One sale is accurate! Every time I calculate the commission at the end of the month, I
It’s the highest!”
Zhu Chaoran squeezed out his left hand and grabbed his butt: "Awesome, you are so smart. Can you tell me why?"
"Huh, aren't you in a hurry to do that?"
The next topic was not suitable for children. Chen Shu coughed a few times and stepped forward to squeeze Zhu Chaoran away.
He took out his mobile phone, pointed at the photo of a middle-aged man entering the room on the screen, and asked politely: "Little girl, what is the number of the fifth floor of this room?"
The front desk clerk glanced at the phone and said coldly: "508."
"Please retrieve the information about the occupants and visitors of this room."
Chen Shu got the hotel's personnel information and compared it with the personnel information he pulled on the police station's intranet before going out.
correct!
Xu Long, from X Province, 47 years old.
You are the one!
Chen Shu took out his police phone, entered Xu Long's ID card information, and pressed OK.
Oh, I work at Connor Group, and my position is still a manager.
Chen Shu smiled coldly in his heart and calmed down.
He picked up the reluctant Zhu Chaoran and hurried out of the hotel. Suddenly he felt dizzy and mentally exhausted, as if he hadn't slept for three days, and his eyelids were as heavy as a thousand pounds.
Chen Shu held his forehead and took a few breaths. He raised his eyes and looked at the sky. A ray of light gradually emerged from the east.
