"Today at noon, I want to clean up the room for Mr. Bi Dalei as usual, Bi Dalei is a frequent visitor here, every day at noon, whether he is or not I will go to clean, this is the rule set before. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo”

Chu Dafu took a step forward: "That's the case, Mr. Bi Dalei explained before, you can't disturb him the rest of the time, and the cleaning of the room is set at noon, and it has always been like this." ”

Yu Yang nodded and motioned for Li Xiaohong to continue, "When I walked to the door of the room, after I rang the doorbell three times, I found that the door was not closed, so I pushed open the door and walked in, I saw, I saw, I saw Bi Dalei lying on the ground, with a knife in his chest, I was frightened, I used the walkie-talkie to say, dead man, and then the manager and security came up!"

Yu Yang didn't find too much abnormality after listening, and continued to ask other people in the hotel, and everyone said the same, they all ran out after hearing Li Xiaohong shouting dead people in the walkie-talkie.

"In this way, Manager Chu, you take us to your monitoring room to take a look at your surveillance video!"

Chu Dafu nodded: "The police officer came with me, our monitoring room is on the first floor, please here!"

Yu Yang followed Chu Dafu into the elevator, and it could be seen that Chu Dafu was a little nervous, Yu Yang looked him up and down: "Are you a little nervous? What's wrong? Are you afraid of me?"

Chu Dafu turned his head and pushed his glasses: "Officer, no, I'm not nervous, I just don't deal with the police often, we, the little people, see you nervous, make you smile." ”

Yu Yang noticed this Chu Dafu After speaking, he secretly wiped his forehead with his left hand, although the action was hidden, Yu Yang still saw it with his afterglow.

"Officer has arrived, here it is!" Exit the elevator and turn right, entering a room with a surveillance room hanging on.

Sofitel is a newly built hotel, the monitoring room is still very new, and Yu Yang has been to the community monitoring room, entertainment venue monitoring room, compared with here is a computer room in the rural junction.

Two eighty-inch main frequencies, and several forty-inch secondary screens next to them, in addition to Yu Yang, there are countless small monitors behind Yu Yang, eight security guards in uniform sat in front of the computer and scanned the area they were responsible for, looking attentive, Manager Chu nodded with satisfaction after seeing it, and turned his head to look at Yu Yang:" Officer, this is our monitoring room, I dare to say that the security system of our hotel is the most advanced in the whole Donghai City Hotel, all the probes used are high-definition probes, and we have thirty monitoring on each floor, without any dead ends, even the fire escape we have arranged monitoring!"

Yu Yang smiled and didn't speak, his eyes swept over the security guards in the monitoring room, it was obvious that these security guards were so dedicated and pretended, Yu Yang and Manager Chu walked in for so long, no one spoke, but there were a lot of discarded cigarette butts on the ground, and there was a strong smell of smoke in the room, someone should have notified them.

"Manager Chu, please ask the person in charge of the monitoring room to come over, I have something to ask!"

Manager Chu nodded, and shouted at a middle-aged man sitting in the innermost: "Captain Ma, come and see, this is a police officer of the criminal police team of the city bureau, come and check the monitoring!"

The captain surnamed Ma nodded and walked in front of Yu Yang: "Hello officer, I am the captain of the first security team, Ma Fei." ”

"Captain Ma, can you call up last night's surveillance video and today's surveillance video to show me!"

Ma Fei glanced at Chu Dafu, stood in place, and then smiled a little embarrassedly: "Officer, I'm sorry, we have the video last night, but from early morning to five o'clock in the morning, we don't!"

Yu Yang's brows furrowed when he heard this, and he didn't understand what this meant: "What do you mean by no? Isn't your surveillance 24 hours a day?

Ma Fei scratched his head: "No, the police officer is not, it's because, since the early hours of yesterday morning, our company's monitoring has been upgraded, and the upgrade time is five hours, and the monitoring is turned off during this time, so, so ......"

"System upgrade, system upgrade is not to go to the nearest public security bureau for the record, by the nearest police station to give guidance, and finally according to the guidance, and in accordance with the guidance for upgrading, have you reported?" Yu Yang is relatively familiar with the hotel monitoring upgrade regulations, when he was in Sijiu City, he once went to a hotel to help the system upgrade, and the specific operation process is quite clear.

Ma Fei walked to his desk and took a document: "Yes, officer, we have reported, we went to report last month, and the police station agreed." ”

After Yu Yang heard it, he took the information handed over by Ma Fei, and looked at it twice, it was indeed a filing document issued by the Public Security Bureau, the time was the 20th of last month, and there was an upgrade guide book presented, which said that he minded that the monitoring upgrade time was April 20th, that is, today, Yu Yang believed that he read the information carefully, and was very annoyed in his heart: "Let you upgrade on April 20th, and you will upgrade in the early morning?" Don't you know that the best time for hotel monitoring upgrade is between 4 pm and 9 pm? Why did you start upgrading in the early hours of the morning?"

Ma Fei turned his head to look at Chu Dafu, wanted to speak again, and thought for a while before slowly speaking: "Because our hotel shift time is six o'clock in the evening, if we upgrade between four o'clock and nine o'clock, we will not be able to hand over the shift, so we choose to upgrade in the middle of the night, so it will not affect our upgrade." ”

Yu Yang turned his head to look at Manager Chu and Ma Fei, and slammed his fist on the table angrily, these people have now added a lot of difficulty to solving the case for their own convenience.

"Officer, officer, don't be angry, we didn't mean to. ”

"Who was on duty in the hotel lobby last night?" There is no surveillance, and now Yu Yang can only ask the relevant personnel to see if he can find some clues.

"It's me!"

Yu Yang glanced at Chu Dafu: "Last night was also your night shift? So how do you go to work now? You have to work 24 hours a shift?"

Chu Dafu smiled: "Officer, you misunderstood, yesterday was because the lobby manager on duty was sick, I took a shift for him, and I will rest the day after tomorrow, and I have no problem on a 24-hour shift!"

"Find a quiet place, I want to ask carefully about what happened last night!"

Chu Dafu nodded: "Okay, how about going to my office?"

"Okay, let's go!"

Yu Yang took the lead and walked out of the monitoring room, and now his mind is full of questions, it is too much of a coincidence that the hotel monitoring has been upgraded, and what is the secret between this Ma Fei and this Chu Dafu, when Ma Fei spoke just now, he kept looking at Chu Dafu.
