At this moment, all the mysteries have been solved by me, I only need the last key step, that is, evidence, but if you want to get the evidence, you must go to the monitoring room on the first floor, at this time I was already anxious, I didn't care to explain to Zhang Qishan, immediately pressed the elevator, ready to go downstairs.

What I hate the most is waiting, the elevator just stayed on the first floor, watching the elevator slowly go up, I always felt that it seemed to be a waste of time, and I didn't know what I thought at the time, I actually ran directly to the staircase, and rushed all the way down the stairs to the first floor, and when I arrived on the first floor, I saw Zhang Qishan standing at the elevator mouth with a look of disdain waiting for me.

"What do you say you're in a hurry, isn't this a waste of time?"

When Zhang Qishan said this, I immediately felt a little blushing, but fortunately Pan An had already walked out at this time, and I immediately stepped forward and said: "Pan An, will you operate the computer and call up the previous surveillance video?" ”

Pan An was stunned for a moment when he saw me so eager, and then nodded and said, "It should be possible, this is not difficult." ”

"Okay, hurry up, I need your help now, I don't have much time left!"

...

Time passed minute by minute, and about half an hour later, Director Li, who was investigating on the rooftop, took everyone to the first floor, not because their investigation was over, but because, at this time, there was another group of policemen waiting on the first floor, and this group of policemen was headed by the unfathomable Director Ouyang.

Seeing that Director Li had come down, and the things I needed had been found, I took Zhang Qishan and Pan An out of the monitoring room together, and came to the hall on the first floor. ”

Director Ouyang first glanced at me proudly, and then nodded: "Okay, you have all worked hard this time, I will definitely give you all a credit when I go back, and the rest of the people will immediately disperse all the guests and waiters in the hotel, and then completely block this hotel, and not let the news of this kind of bull, ghost, snake and god spread." ”

Before Director Ouyang could finish speaking, I stepped forward and smiled: "I don't think there's so much trouble, right?" ”

Director Ouyang still looked at me with an unfathomable expression and said, "Ji Wen, didn't you say yesterday that you could find the murderer?" Now that there is one more life, this case can no longer be interfered by you unrelated people, you go back to Zhongwei City first, and I will tell Bai Qi about the rest of the things. ”

I shook my head and said, "What I mean is that I already know who the murderer is, and I have cracked it along with the murderer's modus operandi, so there is no need to lock down the hotel." ”

Hearing my words, the eyes of everyone present turned to me, even Director Li, who had always believed in me, showed an unbelievable smile at this time, maybe he didn't expect that I would solve the case before Director Ouyang arrived, and I would actually do what I said.

Director Ouyang's eyes also flashed with a hint of surprise, and then he turned into that unfathomable smile again, and nodded: "Okay, I want to see if you really solved the case, or if you are playing tricks, I hope you don't waste our time." ”

I ignored Director Ouyang's harsh words, and turned my head to look at everyone: "Everyone must have a general understanding of this case, Pan An, tell me what you think about this case." ”

Pan An obviously didn't expect me to ask him suddenly, pointed to himself with a surprised face, and saw that I wasn't joking, so he cleared his throat and said: "I'm just a layman, and I don't know what to say, in short, in my opinion, this case is very much like a 'ghost' murder, and there is even an 80% chance that if it is really man-made, then this person is really too powerful, and a murderer who can do such a perfect job is rare even in the past few years in the special case team." ”

Pan An's answer didn't seem to be useful on the surface, but it said the effect I needed, I nodded and said: "That's right, it is estimated that not only Pan An, even everyone present, there are many people who think that this time it may be a 'ghost' killing, and it is even estimated that some people will firmly believe this, but if you think about it carefully, what is the reason why we think that this murder case will be a 'ghost' murder case?" ”

Director Ouyang always looked at me with a sneer, and the people he brought naturally didn't dare to speak easily, and finally Director Li sighed: "Of course it's those surveillance videos, such weird surveillance videos, I haven't seen them at all in the years I've been on the job, Ji Wen, what do you want to say." ”

I snapped my fingers at Director Li and said, "That's right! That's the key to what I'm going to say! Let's think about it, if this surveillance video is removed, will this case still be so weird? On the other hand, it is precisely because we are too convinced of the content in the surveillance video that this small surveillance video has become ironclad proof that this Jincheng Hotel is haunted! ”

When I said this, Director Li seemed to understand what I meant, and said in surprise: "You mean, that surveillance video is fake?" The characters in it were all photoshopped in the later stage? ”

Director Ouyang, who had not spoken, sneered at this time: "Do you think we won't think of this? We have already asked someone to verify the surveillance video, and the content filmed in it is completely real, without any false elements, do you think there is no smarter person in the world than you? ”

I wasn't angry, I smiled slightly: "The director said that he was funny, I didn't have this idea, and I didn't say that the surveillance video was fake." ”

"Then what did you say about what you wanted to express for the past half a day?"

"I just want to say that the content recorded in the surveillance video is completely devoid of any falsehood, but it was manipulated by the murderer at the point in time, so it makes us think that after the deceased died, he appeared on the eighth floor again and continued to kill!"

The most puzzling thing about the whole case is why the so-called 'ghost' of the deceased appears in the surveillance video? However, Zhang Qishan told me when she was recording the video just now that she wanted to save this video and show it to our future children, so that I completely understood that all of us thought that the murderer was too complicated, but in fact, he just used a simple method, not only to hide his murderous behavior, but also to turn this case into a 'ghost murder' incident!

According to my guess, the 'ghost' of the deceased that we see from the surveillance video after the death of the deceased is actually some clips recorded by the surveillance before the deceased's death, and the murderer only needs to carefully preserve these clips, and then perfectly graft them into the time period of the death of the other deceased, so that the illusion of the 'ghost' of the previous deceased killing the latter deceased is formed!

The seven cameras on the eighth floor were originally fixed angles, and they were all filmed in the same place, so even if some of the shots were deleted and then grafted into some clips, there would be no clue at all if there was no inspection by the technical department, and the murderer took advantage of this, and replaced all the shots of killing himself and then transporting the body to the roof of the building with the footage of the 'ghost'!

After I said this, Director Li's eyes widened, and he was speechless for a long time, and finally stammered: "If this is really the case, then everything can be explained!" It turned out to be such a simple truth, but it turned us around! Xiao Fan, immediately let someone check whether the time cut-off point of the surveillance video is coherent, no matter what you find, come back and report to me immediately! ”

The young man behind Director Li named Xiao Fan wearing glasses with a high degree of prescription immediately stood up and saluted, and then led people to the monitoring room to start the investigation.

I secretly looked at Director Ouyang with my spare eyes, only to find that the expression on his face was no longer calm, this Director Ouyang is also a smart person, he must understand that the inference I said is the only fact.

The smile on Director Li's face at this time was getting richer and stronger, and he stepped forward and patted me on the shoulder and said, "It's really yours, such a hidden technique was actually discovered by you, by the way, how did you find out?" ”

I smiled and said, "Actually, this discovery, in addition to thanks to Xiaoshan's prompt, I also want to thank the accident that happened on the day I came to the hotel." ”

I remember very well that when I first came to my room on the eighth floor of the hotel, I was just about to enter the door, but because of my soft hands, I dropped my suitcase on the ground, and smashed the fake plant at the door of our room, and then I helped the fake plant up, but I didn't look carefully at the arrangement of these fake plants in the entire corridor, so I didn't really put the fake plant in place.

Because although these fake plants seem to be placed randomly, if you look closely, you will definitely find that these fake plants look exactly the same, and they are all placed in the same direction.

The first three cases all happened before I came, so everything in the surveillance video did not arouse my suspicions, but the fourth case happened on the night after I came, at that time the fake plants at my door had been placed incorrectly, but on the video in the surveillance video, the plants at my door were placed correctly as before, so I dare to be sure that this surveillance video must have been tampered with!

After hearing this, Director Li sighed and said: "It's better for you young people to be careful, such a small detail can be discovered by you, so since you already know who the murderer is, let's identify him quickly." ”

I smiled and said, "Actually, if I only follow these evidences, it is impossible for me to deduce who the murderer is, but this murderer is too careful, and it is precisely because he is too careful that he allows himself to expose his fatal flaws!" ”
