Because when we left the community before, we asked the security guard at the gate there to see if people in the community could enter at will. But they told us that this was not possible, and that anyone who entered the complex through the main entrance would need to swipe their card to enter.

And this kind of card is only available to people who live in the community.

Then, it is impossible for the murderer to come in through the main entrance of the community, and we should not see his surveillance at the door.

Actually, this doesn't surprise me. For a person who can easily climb over a three-meter-high wall, it should not be difficult to enter such a community.

All that's left is the elevator. By the same token, there was no need for the murderer to take the elevator at all, because the victim's home lived on the seventh floor, which was not high. It doesn't take long to walk up, so I don't have much hope about the monitoring on the elevator.

But since it's all called, let's take a look and go through a process.

However, the moment we turned on the elevator's surveillance and adjusted it to the time of the crime, the people on the screen made me dumbfounded.

That person is him!

I can't forget his eyes and face anyway. And now, everyone knows his face, so there was a commotion among the officers.

"Team Shao, this ......" someone asked me.

I nodded, and said with a serious expression, "I know." This person is him. Don't talk, look, what he's doing! ”

The murderer on the screen stared at the poster of the public service advertisement in the elevator for a long time. This is what I noticed that the child on the screen of the advertisement is still in place, and no one has destroyed it!

It seems that the person who detained the child should be the murderer.

That's when I noticed that the child was a little girl with big eyes and pink lips, and she was a very cute girl if you put it into reality.

The murderer stared at that scene for a long time, until the elevator reached the seventh floor, he seemed to react from his distraction, and walked out of the elevator in a trance.

"He stepped out of the elevator." I said, staring at the screen.

In this way, we sped up the playback of the video.

After about ten minutes, the man was back in the elevator.

"He's back. Ten minutes. Maybe he went in and talked with the deceased for a while. I said.

"But why did the murderer go back to the elevator after killing someone? Didn't he think it was dangerous? A police officer next to him asked puzzled.

"He's the only one who is dangerous to others, and I think that in his dictionary, there may not be any such thing as anyone else being dangerous to him for a while. This murderer is so crazy, and at the same time, he is also qualified to be crazy. I explained.

After returning to the elevator, the murderer still looked very calm, as if nothing had happened. However, at this time, a corpse was already lying in the living room of a family.

As soon as he walked into the elevator, he took out the dagger in his hand, and I could see that it was also a military dagger, anyway, it should be the same model as the one that Wu Zhen gave us last time.

After taking out the dagger, he first pressed the elevator, then turned around and came to the poster, raised the dagger, and began to scratch the dagger on the poster. He was fast and his fingers were nimble, and after a while, the image of the girl was taken down by him, leaving only an outline on the poster.

"Team Shao, what is the murderer doing?" There was another question next to him.

This time, I don't know either. I shook my head and silently watched the murderer's behavior, and suddenly there was an indescribable touch in my heart.

Lily？

Is it possible that Lily is Lily, and Lily is the daughter of the murderer?

It was just one of the inspirations I had when I saw the killer take the image of the little girl. Could it be that after the murderer saw the image on the poster, he felt that the girl looked very much like his daughter, and suddenly felt a feeling in his heart, so he took the image down?

It's very likely.

I hadn't finished watching the surveillance, so I ran to Ouyang Qian's office.

At this time, she was sitting in front of the computer, as if checking some information.

"Qian!" I patted Ouyang Qian's shoulder a little harder, and she turned her head to say hello to me.

"Shao Feng, do you have anything to do with me?"

"Lily, you know what? Have you ever heard of the name Lily from your teacher's mouth? I said quickly and eagerly at Ouyang Qian.

Ouyang Qian seemed a little blindsided, and she didn't react to what I asked this question for.

"Team Shao, what are you talking about? Can you tell me to slow down, I didn't even hear your question clearly. ”

Only then did I realize that I seemed to be a little excited now, so I slowed down my speech and said to Ouyang Qian word by word:

"Do you know that the mentor who taught you martial arts skills in the past mentioned a name named Lily to you?" I asked.

After hearing my question clearly, Ouyang Qian lowered her head, and then began to think about it seriously.

"Hmm...... I don't remember exactly. But I seem to have an impression. Lily...... He seems to have mentioned it to me, but it was only in some conversations when he didn't usually train. Also, it was so long ago that I really don't remember it clearly. ”

"Okay......" I nodded a little disappointed, but I thought it was still very likely.

After all, Ouyang Qian said it herself just now, she has an impression of this name, but she can't remember it clearly. As long as there is an impression, then this "Lily" is likely to exist, and for the murderer, she is still a very important person!

It may even be his daughter.

In other words, if we can trace it through this clue, we can find the person who was once in a relationship with his daughter, then we can find the next victim, or the possible victim, then we have a chance to stop the next crime, and even let the murderer fall into the net!

But where do you start......

Suddenly, I remembered a detail.

"Qian, I want to ask you one more question." I said to Ouyang Qian.

She nodded, motioning for me to ask questions.

"Do you remember where you first met your teacher when you were a child, and where was it?"

Ouyang Qian nodded: "Of course I remember." I once told you that the place where I first met him was in the juvenile detention center. ”
