"Did you see it in this building? Why do you think this person is suspicious?" Ning Shuyi asked.

"Because this person has appeared more than once, he has been met by me two or three times, and when you say that I can't meet him, how many times does he have to appear, who dares to think!"

The female neighbor said to them nervously, "That man is not a resident of our building at all, there is only one floor upstairs in my house, and there is a teacher who is about my age and an old couple.

The teacher's child is in junior high school, and the child of the old couple has settled abroad and is not coming back at all.

So there's no such person upstairs at all.

But every time I saw this man, he took the elevator directly to the top floor, got off the elevator and went down the stairs.

The first time I met it, I was taken aback, and I didn't think much about it at the time, so I opened the door and went home.

The second time I met him again, I felt a little strange, I was worried that it was not the kind of habitual thief who was burglary, and ran into our building to step on it, so I paid extra attention to it, I should have opened the door and went home, I was not in a hurry, and stood in the corridor for a while.

As a result, I waited for a while, and I didn't hear any movement in the hallway, so I went down half a floor to take a look, and guess what?

The man was sitting on the stairs, fiddling around with a cell phone.

I asked him what he was doing, and he didn't look back, so he got up and went downstairs as if he didn't hear me.

But you said that if he really hadn't heard it, he wouldn't have run away so quickly, he must have some kind of weak purpose, and he was afraid of revealing his stuff after being targeted by me, so he ran away quickly."

"So you haven't seen this person's appearance clearly, what about the others? Is there a way to estimate the age?" Ning Shuyi asked.

The female neighbor thought for a moment, "It stands to reason that the age should not be too old, just the one who is dressed is only twenty years old, but whether it will be deliberately dressed like that, so that people can't guess how old he is, then I don't know."

"The few times you met him, he took the elevator straight to the top floor and then down the stairs?"

"Yes, every time! Otherwise, I wouldn't be suspicious!" The female neighbor nodded busily, "Originally, I was afraid that a thief would step on it, but now I'm even more worried, I'm afraid that if it's a murderer...... I've bumped into him before, and I've chased him and asked him what he's doing, so don't think I know anything and retaliate against me!"

"Don't worry, let's go to the property's control room and check the surveillance to see what's going on." Ning Shuyi comforted her, "Can you help us roughly recall the last time we saw this suspicious character?" Date, approximate time, that will help us a lot!"

"Okay! No problem!" As soon as she heard that Ning Shuyi was willing to help find out, the female neighbor was greatly relieved, and her response was extremely refreshing.

With the information provided by the female neighbor, the three people who were originally going to leave for the bureau were diverted to the monitoring room of the property, and first called up the elevator monitoring according to the approximate time provided by the female neighbor when they last saw the mysterious person, and sure enough, they saw the person mentioned by the female neighbor.

The person on the screen looks to be at least 185 cm tall, with jeans and sneakers on the bottom, a black down jacket on the upper body, and a royal blue hooded sweatshirt with a hat buttoned on the head, exactly like what the female neighbor said.

This person was also wearing a thick black mask on his face, made of windproof and warm material, which directly covered two-thirds of his face, revealing only a pair of eyes, which were still hidden behind broken bangs.

Huo Yan asked the property staff to help pause the picture, zoom in as much as possible, look at it carefully, and then signaled to continue playing the surveillance video.

The young man in the picture took the elevator all the way to the top floor, and when the elevator door opened, he walked straight out.

The elevator monitoring of this unit is not installed in a corner of one side of the elevator as usual, but on the side of the elevator door, and the inner wall of the elevator door happens to be a mirror.

The camera can clearly see through the mirror that after the man stepped out of the elevator on the top floor, he did not turn around at all to the two households on this floor

Instead, one of the residents walked straight in the direction of the stairwell.

It's no wonder that the female neighbor was suspicious.

Ning Shuyi asked the property staff to help play back the video, and she felt that although this young man was dressed without the slightest impression, he looked with an indescribable sense of familiarity.

She looked at Huo Yan, in terms of recognizing people and checking details, Huo Yan's ability was definitely unbeatable, and the rest of the team together may not be comparable.

Huo Yan really knew it in his heart, and nodded to Ning Shuyi.

Ning Shuyi asked the property for a few videos that were still in storage according to the dates provided by the female neighbor, and then the three of them left the community and drove back to the bureau.

After this circle of busyness, most of the morning has passed, and Kang Ge's help when he returns to the bureau is also finished, there are other things to be busy with, and the rest of the things will be left to Ning Shuyi and Huo Yan to continue.

"The person in the video, do you have an impression?" Ning Shuyi sat down at the desk, asked Huo Yan while turning on the computer, preparing to adjust the elevator monitoring on the day of the crime scene that had been saved before.

"Yes." Huo Yan nodded, "The hair on the forehead is dyed light yellow with a lock, and the studs on the ears are the same."

"I know you have good eyesight, and you can definitely see more details!" Ning Shuyi has been dealing with Huo Yan for a long time, and he is no longer surprised by his ability, but he still admires him very much, "I didn't find the two places you mentioned.

I just think that people's clothing and hairstyles are relatively easy to change, but once things like standing and walking are formed, it is difficult to change, especially inadvertently, it is even more difficult to hide.

I thought the man's walking posture was very familiar, as if I had seen it in the surveillance video before, but I was not sure.

Now add in the details you've noticed, and I'm pretty sure."

The expression on Huo Yan's face was faint, but his waist seemed to be a little straighter.

The video on the day of the crime was called up, and Ning Shuyi considered that Xu Wenbiao had come to the scene of the crime early in the morning, but he had not met anyone, so he pulled the time schedule to after Xu Wenbiao left and carefully screened it.

About more than 20 minutes after Xu Wenbiao left Hong Xinli's residence, it was also past the morning rush hour for work, and the elevator door that had been quiet for a long time opened again, and a person wearing an ankle-length dark gray down coat came in.

The man looked very tall, with a down jacket and hat buttoned over his head, and a mask on his face.

But the walking posture, as well as a pinch of yellow hair on the forehead, and the faintly visible earrings, all told them that the suspicious person provided by the female neighbor really appeared on the day of the crime.
