Li Bing asked anxiously: "Then what about the future, where did the people go, and what happened to you being tied up." ”

The medical officer said helplessly: "When the car drove here, the man suddenly shouted to stop, and before we could react, he actually took out a pistol and threatened to kill us if we didn't stop, and the driver was forced to stop the car on the side of the road." ”

"The man, wielding a pistol, ordered me to tear the sheets covering the patient from the ambulance, tied up several of my colleagues one by one as he asked, and stuffed strips of cloth in their mouths, and finally, he tied me up like this."

Captain Sun stared at the medical staff and said, "Then what about later, how did that man take the patient away?" ”

The medical staff oozed sweat on his forehead, and said nervously: "At the beginning, after we received an emergency call and arrived at the scene, the female patient was really unconscious, and the pulse was a little messy, when our car drove here, after being subdued by the man, the woman was still not awake, I saw from the car's mirror, he carried the woman into a parked car on the side of the road, and then he drove away, not long after, you also chased." ”

Seeing that he couldn't ask any more valuable clues, Captain Sun said to Li Bing: "Li Bing, you go back to the hotel with me, let's take a good look at the surveillance video." ”

After returning to the hotel, Captain Sun and Li Bing began to watch the video carefully.

Suddenly, Captain Sun's brows tightened, and he said to Li Bing: "Li Bing, did the medical staff in the ambulance just now say that they went to the thirteenth floor to pick up the man and the 'patient'. ”

Li Bing nodded, he also had doubts in his heart, but he didn't say it, he was thinking about what was going on.

Captain Sun stood up suddenly: "No, the medical staff in the ambulance lied, you see, since the footage of Zhao Wan'er's disappearance from the elevator can be recorded and preserved under the surveillance video, why is there no surveillance video of the medical staff going up and down the stairs, isn't it too strange." ”

A criminal policeman next to him was also aware of this problem, and he said while thinking: "Captain Sun, you mean that those medical personnel did not get on the elevator at all, but went directly to the stairs to pick up the man and the 'patient'. ”

Captain Sun frowned and said: "Yes, if that's the case, it means that those medical personnel are the accomplices of the perpetrator, they were kidnapped, it's just a bitter trick, by the way, Xiao Wang, you go and call the two bar waiters." ”

After a while, the two waitresses came to Captain Sun tremblingly,

Captain Sun said solemnly: "You have a good recall, the medical staff who got off the ambulance, and the auspicious process after they entered the hotel. ”

A waitress said: "Captain Sun, at that time, Xiao Li and I were bored and attracted by the ambulance, and we were wondering why someone was sick and didn't tell us directly to the main station." ”

The waiter named Xiao Li also said: "At that time, there was almost no one in the hotel lobby, and the two of us watched these medical staff enter the elevator and came down on a stretcher after a while. ”

Captain Sun asked solemnly: "You two can see clearly, there won't be any problems, you know, everything you said is very serious in nature." ”

The two waitresses were very sure that they would never be mistaken, seeing this, Captain Sun waved his hand and said, "I know, thank you, you two should leave first, if anything happens, I have to ask you to cooperate with the investigation." ”

When the two waitresses left, Captain Sun was puzzled, obviously the two waitresses saw that they were getting down from the elevator, how could they not find out from the video,

He squinted and glanced at it, and saw that Li Bing was still staring at the surveillance, and from time to time calling back and forth to watch the video, he couldn't help but feel a little happy in his heart, and he asked anxiously: "Li Bing, have you found anything?" ”

Li Bing didn't raise his head, pointed to the video screen and said, "Captain Sun, look, this video is no different." ”

Captain Sun was a little puzzled, he looked at it a few times and didn't find anything special.

Li Bing pointed to the picture and said, "Captain Sun, take a look, is there an imperceptible beating between these two pictures." ”

Captain Sun was reminded by Li Bingyi and took a closer look, and sure enough, there was a place in the video that jumped obviously.

Captain Sun asked, "Li Bing, can you explain what's so strange about this beating in the video screen?" ”

Li Bing thought for a while, and finally understood, and couldn't help but proudly take out the cigarette, and gave a stick to several criminal policemen and Zhang Yuanshan and Qian Yiduo present.

After he lit his cigarette, he said unhurriedly: "Captain Sun, those medical staff are not lying, they are indeed going up and down from the elevator as the waiter said. ”

Captain Sun was shocked: "Li Bing, are you saying that there is a mysterious person's internal response in the security room of this hotel." ”

Li Bing shook his head and said, "Captain Sun, this is impossible, because we have been in the security room, so it can be ruled out that the security guards are cooperating with the case, and I have already figured out the whole process of the matter." ”

Li Bing speculated that the course of events should be like this,

That mysterious person, if nothing else, should be Wang Liping, because he secretly has a very close relationship with Yang Yibing, who has died, he naturally got the key to the relevant departments in the hotel.

Taking advantage of the negligence of hotel management, Wang Liping secretly entered the hotel security room with his own key and copied the elevator surveillance video.

When he asked Zhao Wan'er to come to the thirteenth floor, he first repeated his old tricks and created the strange scene in the elevator before Xu Mei disappeared.

Then, when Zhao Wan'er leaned out, Wang Liping attacked from behind her and covered Zhao Wan'er's mouth with a towel soaked in psychedelics, making her unconscious in an instant.

What is even more admirable is that Wang Liping used the pre-prepared microcomputer and the copy of the hotel surveillance video to connect to the hotel monitoring line.

In this case, the monitoring in the hotel elevator is actually constantly playing the copy he prepared in advance, so when the medical staff get on and off the elevator, the monitoring should have been invalidated, so it is not recorded.

Why did Wang Liping do this, first of all, it could skillfully take Zhao Wan'er and himself out of the hotel through the ambulance without arousing suspicion, and also created trouble for the police to track him down and buy him time to commit the crime; In addition, it can also create a stronger sense of mystery for people who pay attention to this incident, making the rumor that Zhao Wan'er was indeed killed by ghosts and gods more convincing.

As for the route of the ambulance, he had already surveyed it and calculated the necessary route from the emergency center to the hotel.

Therefore, Wang Liping parked the car on the side of the road in advance, and when the ambulance arrived, he took out his gun and subdued the first responders in the car, so as to calmly take the unconscious Zhao Wan'er away.
