"In addition to you, where are the three security guards here now?" Yu Yang frowned, it seems that this security guard surnamed Li should not know that anyone has touched the computer, and now the target of suspicion has been changed to the remaining three security guards, someone must have entered the video surveillance room, otherwise, no one would have changed the monitoring mode. Pen, fun, and www.biquge.info

"There is also an old Liu, who is smoking outside now, and two people are on the night shift and only go to work at four o'clock in the afternoon, police officer, some of them must know who has entered here, I really don't know, police officer, you have to believe me!"

Yu Yang nodded: "You go and call Lao Liu back, don't tell him anything, just let him in!"

Xiao Li nodded like a chicken pecking rice: "Okay officer, I'll go now, you wait, wait!" After finishing speaking, he glanced up at Zhu Yu and immediately ran out of the surveillance video room.

"Two police officers, I'm sorry, I must manage the staff in my store well, it's my mistake, I will definitely train the staff in the store well, so that they can strengthen their awareness of prevention, police officer, I'm really sorry, I'm sorry to cause you trouble!" After Zhu Yu saw Xiao Li walk out of the video surveillance room, he immediately began to apologize to Yu Yang and Fan Mingyue, now is the time for public relations, if it is not handled well, the store may be seized.

Yu Yang smiled and shook his head helplessly, when he got out of the car just now, he already had a bad premonition in his heart, maybe there would be nothing to gain from coming over this time, but he didn't expect to be guessed by himself, and sure enough, there was a problem with the monitoring of Dior Coffee.

Yu Yang's heart faintly had a little sense of excitement, this time the opponent seemed to be a very difficult character, he had already set up a game and waited for the police to jump in, and now there were almost no useful clues.

"Store Manager Zhu, I hope that the staff in your store can be trained well, this time we are here to transfer you to monitor, if there is a criminal case in your store, if there is a problem with your monitoring, when the time comes, it is not as simple as letting you train employees!"

"Yes, yes, yes, Officer Fan, you are right, I will definitely strengthen the training of employees, this kind of thing will never happen in the future, the two police officers can rest assured, I will definitely start to do it immediately!" After Zhu Yu heard Fan Mingyue's words, he nodded constantly, and he had already made the decision to fire this Xiao Li in his heart.

"Store manager, two police officers, Lao Liu is here!" Xiao Li didn't know that he was about to be fired by Zhu Yu, so he walked into the house with Lao Liu, who was smoking in the parking lot outside the house just now, and stood sideways to the side, looking at Yu Yang and Fan Mingyue.

"You go out first, we have something to ask him!"

Xiao Li immediately nodded: "Okay, officer, I'll go to the parking lot to have a look!" Xiao Li nodded and ran out of the house, Lao Liu, who had just entered the door, looked at Yu Yang and Fan Mingyue a little nervously, although this Xiao Li promised Yu Yang and Fan Mingyue not to say anything, he should have said something to Lao Liu just now.

Lao Liu is a lot older than Xiao Li, he looks like he should be in his fifties, his hair is already a little gray, and there are many units in China and the company's doorman, it is better to say that he is the janitor, most of them are elderly people, Lao Liu is a typical Chinese-style doorman, and he is older.

"Lao Liu, right? We are from the criminal police detachment of the Municipal Bureau, we have something to ask you, why was the surveillance video mode modified to real-time monitoring, did you change it?" Yu Yang took out a cigarette from his pocket, handed it over, and asked with a smile.

Lao Liu glanced at Zhu Yu, took the cigarette, and immediately shook his head after hearing Yu Yang's inquiry: "Officer, I really don't know what you're talking about!"

"It's just something on the computer, have you ever touched it? This computer!" Yu Yang pointed to the computer where Xiao Li was playing the game just now.

Lao Liu immediately shook his head: "Two police officers, I also have computers at home, but I really can't understand these things, so I usually watch Xiao Li and Xiao Wang play, I never touch these things, I'm afraid of breaking them, I can't figure it out, occasionally on the night shift, I will ask Xiao Li or Xiao Wang to get me a movie to watch, but I never touch the computer myself, it's after they order it for me, I watch them fiddle!"

After Yu Yang heard this, he nodded, although now very old people can use computers, but there are still some people who don't know how to use computers at all, Lao Liu belongs to one of them, in his eyes the computer is a complex and difficult thing to understand,

"Then think about it, in addition to the security guards at work, there are also people who have entered your monitoring room, Store Manager Zhu, when was the last time you were transferred to monitoring?"

Zhu Yu thought for a while: "It seems that about ten days ago, there was a guest's mobile phone stolen, suspected that it was stolen by our employees, but when I watched the video, I found that it was really one of our employees who did it, and that person was sent to the police station by us, and there should be a record at the Park Road police station!"

Yu Yang nodded, frowning slightly: "Was it all of you who were present to check this surveillance at that time?"

Store Manager Zhu nodded: "I was in the store at the time, and I handled this matter single-handedly, I remember very clearly, Xiao Li and Lao Liu were both there at that time!"

"Thank you, Store Manager Zhu, Lao Liu, in the past ten days, has anyone ever entered the video surveillance room? You think about it carefully, except for a few of you security guards, even if it is an employee in your store, as long as you remember, you can say it!"

Lao Liu nodded while thinking: "Officer, can I think while smoking?" I'm a little nervous!"

Yu Yang smiled: "It's okay, you smoke, don't worry about it slowly, I heard that people of your age have a very good memory, don't worry!"

Lao Liu laughed, took out a lighter from his pocket and lit it for himself, while swallowing the clouds and spitting out the fog, he thought slowly, and finally shook his head slowly: "Our video surveillance room, generally rarely come, in fact, when our security guards work, they rarely stay here, this is a resting place, the waiters upstairs rarely come down, and we have no dealings, recently come to our monitoring room, except for Manager Zhu, I don't think of anyone else!"

"Do you think about it and make sure there's no one?"

Lao Liu nodded firmly: "I'm sure there is no one!Well, Store Manager Zhu has been here twice, but he is standing at the door, I don't know anything else!"
