At 9:45, Qin Feng's figure appeared in the elevator monitoring, and a few minutes later, Qin Feng drove his wind-pulling Porsche and left the hotel with a throttle.

At 9:50, Liu Zhenzhen came out of the room, got off the elevator and returned to the banquet hall.

In Liu Zhenzhen's words, she stood in front of the window on the 8th floor and watched Qin Feng's car turn out of the hotel gate.

Qin Feng is gone, she naturally has to look for a new target.

However, her expression did not look happy.

She said: "I didn't expect that the men in my cousin's company were all elm bumps that didn't understand the amorous feelings, and I knew that I wouldn't come to this drinking party, wasting my time." ”

On this night, the elevator at the entrance of the banquet hall was very lively.

At 9:35, Luo Qiao appeared in the elevator surveillance, which did show that she pressed the button on the 8th floor, but the elevator door did open on the 7th floor.

At 10:05, the figure of the victim Wu Qian appeared in the surveillance, and it was a uniformed male waiter who entered the elevator with her. The male waiter got off the elevator on the 3rd floor, the two of them did not communicate the whole time, and Wu Qian reached the 8th floor alone.

At 10:08, a young man dressed as a hotel waiter took the elevator to the 7th floor.

The young man did not hesitate, and after entering the elevator, he pressed the button directly to the 7th floor.

At 10:12, another young man dressed in a hotel waiter costume took the elevator to the 7th floor.

Both of them looked like they were in a hurry.

At 10:25, Wu Qian got on the elevator from the 8th floor, and for some reason, the elevator door was opened again on the 7th floor, and Wu Qian hesitated for a moment before going straight out of the elevator.

Su Mu looked at the monitoring screen on the computer and asked Wang Dalong to press the pause button.

The key is here, after the elevator door on the 7th floor opened, a vague shadow outside the elevator door was reflected from the elevator door, and the shadow stretched out his hand and beckoned to Wu Qian, and Wu Qian followed out.

Unfortunately, only one shadow can be seen in the surveillance, and the owner of the shadow is most likely the murderer of Wu Qian.

According to the surveillance, Wu Qian was the fourth person to reach the 7th floor from the elevator that night.

From 10:05 to 10:25, she spent nearly 20 minutes on the 8th floor. Could this person be the shadow that appeared on the 7th floor?

Su Mu thought of Huang Qiang and Zhao Meng, this night, before Wu Qian entered the 7th floor, the known people who entered the 7th floor from different passages, in addition to Luo Qiao, there were also Huang Qiang and Zhao Meng, and there were two waiters.

Of course, it may also be that other staff members of the hotel who are qualified to enter the 7th floor, on the question of which employees are qualified to enter the 7th floor, Su Mu asked Huang Qiang before, Huang Qiang said that in addition to him, there are electricians and security guards on duty.

As for why the doors to the security passage on the left side of the building are locked? Huang Qiang's explanation is this.

After the hotel exits the safe passage on the left, there is a construction site that has not been started for a long time, and the construction site is blocked by a high fence, so this safe passage is of little use.

The right side of the building is unlocked, so in the event of a security incident, hotel personnel can go down the right side of the building.

At 10:30, Zhou Yu got on the elevator, his destination was supposed to be the 8th floor, but the elevator was also opened on the 7th floor, and then he walked out of the elevator.

Zhou Yu was the fifth person to take the elevator to the 7th floor this night.

Wu Qian went up to the 7th floor before him, and that shadow naturally couldn't be him.

But does Wu Qian's death have anything to do with him? Regarding Zhou Yu's suspicions, Su Mu felt that what Luo Qiao said also had a certain amount of truth.

At 10:55, the sixth person to reach the 7th floor this night was Luo Qiao's classmate Jiang Kai.

At present, after Jiang Kai went up to the 7th floor, the hotel security guards also arrived on the 7th floor one after another, so Jiang Kai was basically not suspicious.

But among these people, who is the faceless man Luo Qiao said?

According to Luo Qiao's description, this faceless man is not tall, and his height will not exceed 170 by eye, which is no different from Zhou Yu's description.

However, from the monitoring point of view. So far, among the people who have entered the 7th floor, there is no one who meets the height characteristics of the faceless man.

Therefore, the faceless man may have entered the 7th floor through another passageway.

When the hotel security arrived on the 7th floor, there were a lot of people who watched the excitement one after another, and it was not ruled out that the real murderer was among these people, which also made it quite difficult for the police to investigate.

summoned Zhou Yu again, Zhou Yu still insisted that he was a beautiful woman, and took out the message sent by the beautiful woman.

As for the first questioning, why didn't he tell him about his date with the beautiful woman?

His reason is that this ambiguous text message, to put it bluntly, means to make an appointment, he doesn't have anything, but after all, people are girls, at least they have to save a little face.

Zhao Meng, the text message she distributed to Zhou Yu at 10:26 p.m. read: The night is long, I am lonely, I am waiting in room 8802 to spend a good night with you.

Zhou Yu said that the beauty has an appointment, naturally can not live up to it, after receiving the information, he took the elevator to the 8th floor, who knew that the elevator door was opened on the 7th floor, and by mistake saved Luo Qiao's life.

Zhao Meng, when she sat opposite Su Mu again, Su Mu remembered what Huang Qiang said, Zhao Meng, her appearance is really not in the hearts of all men, it can be described in a word.

Although Zhao Meng's face is very cold, her voice is beautiful and delicate, if it weren't for that face, I believe that any man would not be able to resist her numbing voice.

Zhao Meng is also very straightforward, she said that she understands her appearance.

This night, when she was dealing with men under the mask, she was still very confident.

When he couldn't help himself in the hotel room with Huang Qiang, the mask was given by Huang Qiang.

She could feel the disappointment in Huang Qiang's eyes at that time, after the two of them made a hasty decision, Huang Qiang didn't say a word, put on his clothes and escaped.

Zhao Meng said: "Officer, I am 26 years old this year, and like most girls, I long for love, for marriage, and for a man who accepts me. But the truth is, with my appearance, men flock to me when they see me, and they are afraid to avoid it.

After Huang Qiang left, I remembered Zhou Yu who had a conversation with me at night. He was a modest man, and in the course of our conversation, I hinted to him several times that I might not look as good as I could. But he made it clear that what he values is only the connotation of a person, and as for the appearance, it is okay.

So, after Huang Qiang left, I immediately sent him a message and asked him to come to the room to find me, which was also a chance for me. ”

According to Zhao Meng, Zhao Meng sent a message to Zhou Yu about twenty minutes after Huang Qiang left the room.

In other words, Huang Qiang left the room at about 10 o'clock, and after that, it was not until 11:03 p.m. that Huang Qiang was once again found in the elevator monitoring from the 8th floor.

So, where did Huang Qiang go for nearly an hour?
