"What a hell! How is this possible?" Chengzi stared at the surveillance screen with a blank expression, unable to believe what he saw. Han Xu and Chengzi made a general survey of the environment of the villa area before coming to the property to collect surveillance. To be precise, the outer wall of the villa area is so high that it can almost be said to be insurmountable for ordinary people. "Could he be able to climb over walls?" Chengzi also thought of the protective measures around the villa area. "It's impossible. Even if the opponent has a certain climbing ability, how can he climb over those walls with an injured burden?" "Yeah, I can't even get over it! Let alone take someone with me." Chengzi gave up the unrealistic idea, "Then how did he get out?" "We don't even know how he got in." Hearing Han Xu say this, Chengzi was even more confused, "That is to say, how did he get in? Could it be that he came in hiding in other owners' cars?" Han Xu also thought about this possibility, but then gave it up. "From the time Jiang Zigui returned to the villa the day before yesterday, until now, there have been only a few cars coming in and out.
The murderer may have taken the opportunity to hide in another owner's car and enter the villa area, but if you look at the surveillance video, every time the car comes in, it never goes out again. It would be almost impossible for the murderer to take the injured Jiang Zigui and get out in another car, unless he had an accomplice. But then why bother changing cars? " "That means that there are two people in the villa area who are responsible for the murderer?" Chengzi thought wrongly. "This possibility is too small, but you can check the property and owners to see if anyone has the motive and conditions to commit the crime." When the property manager on the side heard this, his face turned green, "I told you two police officers, our security here has always been strict and compliant, and this kind of situation cannot happen. What's more, I know the owners of the few cars that went out. With their worth, there is no need to kidnap others. " When Han Xu and Chengzi heard what the property manager said, they felt that they had taken a detour. So how did the murderer get in? And how could he take Jiang Zigui away so easily without anyone noticing? Han Xu couldn't figure it out for a moment and turned his attention to the surveillance video. "Chengzi, please replay the footage captured by the surveillance camera." When playing the video just now, in order to save time, I increased the multiplier. Han Xu always felt like he was missing something. Hearing this, Chengzi returned the surveillance screen to the day before yesterday and started playing it when Jiang Zigui drove into the villa area. "No, Chengzi, push the time forward a little further and pull out the video of Jiang Zi before he returned to the villa area." Chengzi didn't follow Han Xu's thinking, but still followed the instructions and adjusted the surveillance screen to the Wednesday before Jiang Zihui returned to the villa area. The dynamic picture is beating rapidly. Han Xu turned on his skills unconsciously and captured every detail.
If Lao Zhang were here, he would be shocked again. "Stop, go back ten seconds!" Han Xu seemed to have discovered something. The picture freezes. But there was nothing above, and there was nothing outside the gate of the deserted villa area. "No problem!" Cheng Zi turned around and asked doubtfully. Han Xu smiled, "Look at the time, there is a problem with the continuity of this surveillance video." "What do you mean? Why am I so confused?" Chengzi looked at the time in the upper left corner of the screen again. 12:00:30 AM. "Go back and play it again slowly." Cheng Zi was confused and did as he was told. Sure enough, when the time reached 12:00 minutes and 30 seconds, it quickly changed to 12:01 minutes and 10 seconds. The screen was lost for 40 seconds for no reason. Chengzi frowned tightly, "Did someone process the surveillance video and tamper with it? Did he deliberately cut off more than 40 seconds?" The property manager waved his hands repeatedly, "Absolutely impossible! What on earth is going on?" "What else do I want to ask you? Tell me, what's going on?" Cheng Zi glared at the property manager. "I just came here not long ago. I really don't know what's going on. Two police officers, why don't I get the security guards on duty for you. They must know something!" the property manager hurriedly replied. Han Xu nodded in agreement. The property manager ran out of the control room as if he had been granted amnesty. Cheng Zi took the opportunity and said, "More than 40 seconds is enough for the murderer to enter the villa area, but why was he not seen by the security? Is there a problem with the security?" Han Xu didn't say anything, but asked Chengzi to adjust the surveillance video to last night. Sure enough, at 4:00:30 in the morning, the screen quickly jumped to 4:01:10. Still missing 40 seconds. Chengzi couldn't help but give Han Xu a thumbs up, "With these two periods of window, we can explain the murderer's crime behavior. He entered the villa area in the early morning of Wednesday when Jiang Zigui returned to the villa, then lurked for a while, and took the injured Jiang Zigui away from the villa area last night, or early this morning. " Han Xu nodded and said, "Nine times out of ten, this is the case. Otherwise, Jiang Zigui's mysterious disappearance cannot be explained." After a while, the property manager came in with two young people wearing security uniforms. "Two police officers, I've called for them. Please tell them quickly. How come the surveillance was shortened for a period of time? Did you do anything?" Hearing the property manager's question, the two security guards' faces changed.
One of them looked at the property manager with disdain, and then said to Han Xu and the others, "Hello, officers! The thing is, this security system has just been installed not long ago, and it is very advanced. In order to ensure that the monitoring can always operate normally, a cloud upload function has been added." "What do you mean?" Orange didn't understand again. Han Xu had heard of this function before, and took over the conversation, "You mean, this system will restart regularly?" The security guard didn't expect that the young police officer in front of him knew more about the security system than they did. "The police officer is right. This monitoring system will restart once a week, around 12 o'clock in the morning on Wednesday." The time is right! Orange asked again, "Then why did it restart last night, oh, no, it was this morning?" The security guard replied without thinking, "The restart at dawn on Wednesday is to upload a week's monitoring data to the cloud server, and then it will restart once in two or three days to clear the cache and ensure the normal operation of the system." "So that's it!" Orange understood it completely. However, Han Xu fell into deep thought again. The lighter in his palm kept spinning... "The truth is out, Han Xu, what are you thinking about?" Chengzi asked in confusion. "How did the murderer know that the system would restart at a fixed time? And the time was so accurate." "Yes, it was only 40 seconds, the time was too accurate!"
