There were no curtains on the window in Wang Luyao's living room. It was impossible for the murderer to cover it with curtains so as not to leave traces. If the murderer wanted to close the window inadvertently, he must have worn gloves.

Therefore, as long as Chen Yan finds out who among these 12 people is wearing gloves, wouldn't it be over?

Two people!

Yesterday morning after 8 o'clock, in the ten minutes from when Wang Luyao's mother reported the incident to when Zhang Yaoming showed up at the scene, only two of the 12 property staff who came in and out were wearing gloves.

Judging from the uniforms they wore, they were security guards.

Among the two security guards, Chen Yan identified the suspect at first sight.

Two security guards, one fat and one thin.

The two security guards were both about 1.7 meters tall, but the fat security guard's face was full of nervousness and fear, while the calmness in the eyes of the other security guard made Chen Yan a little scared.

What does the average person look like when they see a dead person?

But this security guard seemed not to see anything. After Zhang Yaoming and others arrived, he kept hiding at the back of the team and observed carefully, but never said a word.

Not even a word was exchanged with the colleague next to me.

This person's characteristics are very similar to the conclusions drawn by Chen Yan's criminal psychological profile.

Taking out his mobile phone, Chen Yan immediately dialed Zhang Yaoming's number: "Team Zhang, send someone to show me the transcripts of the 12 property personnel who were on site that day.

"OK."

After a while, Zhang Yaoming personally handed over the interrogation transcripts of the 12 property owners present that day to Chen Yan.

"Team Leader Chen, have you discovered anything?"

Chen Yan took the interrogation transcript and nodded: "We have found something, but we are not sure yet."

As Chen Yan spoke, he flipped through the transcripts and quickly found the interrogation transcript of the security guard.

"Xie Shi'an?"

Pull out this transcript and read it carefully.

The record was very simple and contained no valuable clues. Xie Shian was the security guard on duty that day.

The security guard in the community where Wang Luyao lives works in two shifts, with the shift taking over at 6 o'clock every morning and evening.

Xie Shian and the fat security guard he was with took over at 6 o'clock this morning.

Coincidentally, yesterday morning Xie Shi'an and the fat security guard were patrolling under the building where Wang Luyao lived. At 8 o'clock, they heard someone shouting murder, so they ran upstairs.

These two men were the first to arrive at the scene.

Later, after Xie Shian reported through the intercom, other property management personnel arrived one after another.

Xie Shi'an, a community security guard, must be familiar with the fact that the monitoring equipment in the community is restarted at 12 noon every day.

But something isn't quite right.

The security guards in the community work in two shifts, with the same person working on the day shift for one month and the night shift for one month.

This month Xie Shian and Fatty Security Guard are on day shift, which means they work from 6 a.m. to 6 p.m. every day.

Then it would be impossible for him to enter Wang Luyao's house at 12 noon the day before the incident and ambush him while the surveillance system was restarting.

If he entered Wang Luyao's home at other times after get off work, the video surveillance would definitely leave traces.

"Team Zhang, check Xie Shi'an's duty status, especially whether he was on duty the day before the incident."

"yes!"

After Zhang Yaoming left, Chen Yan suddenly thought of what Liu Qingshan had investigated about the maintenance of the entrance door of Wang Luyao's home.

"Master, what is the name of the security guard who had a quarrel with Wang Luyao because she was repairing the entrance door?"

"I didn't check the specific name. I just looked at the surveillance video of the person involved. Wait a minute, I'll check it and let you know."

"OK."

Ten minutes later.

Liu Qingshan and Zhang Yaoming brought back investigation news at the same time.

"Team Leader Chen, I just contacted the property management of the community. The security guard you mentioned was on vacation on the day of the incident and did not go to work."

Not at work?

Gan!

Chen Yan looked at Liu Qingshan and asked directly without waiting for the other party to speak: "Master, is that security guard named Xie Shi'an?"

"Huh? How do you know?

Grass!

really!

Sure enough it was him!

Chen Yan looked at the photos on the interrogation record in his hand, and his eyes lit up!

"Arrest Xie Shian immediately!"

Half an hour later, Chen Yan saw the security guard in Interrogation Room No. 1.

Xie Shi'an, who was sitting in the interrogation chair, remained calm even though he was now handcuffed.

Chen Yan is interrogating himself.

"Just because you had a quarrel with Wang Luyao and she mocked you for being a security guard for the rest of your life, you killed her?"

No nonsense, judging from the information currently available, Wang Luyao and Xie Shian only had contact once.

The two had a little quarrel while repairing the door.

Xie Shi'an raised his head in confusion: "Officer, I don't quite understand what you are talking about."

"You mean I killed the owner?"

"How is this possible? Why should I kill her for no reason? And didn't you say that the owner committed suicide? What does it have to do with me?"

Looking at Xie Shi'an who was stubbornly resisting, Chen Yan's lips curled up slightly.

"You really don't shed tears until you see the coffin."

"Xie Shi'an, the reason why I'm sitting across from you now is to give you a chance."

"Don't think that your process of killing Wang Luyao was seamless."

"Don't even think that we can't lock you in because you didn't leave any clues at the scene."

"Otherwise, you wouldn't be sitting here now."

Xie Shi'an's eyes were a little dodgey at the moment, and he was still a little confused.

Perhaps, at this moment, he was also thinking about how Chen Yan and the others found him.

However, Xie Shian is obviously ready to fight stubbornly.

"Officer, I don't know what you mean."

"I have never killed anyone. If the owner did not commit suicide, then you should go find her murderer instead of locking me up here without any evidence..."

"Although I'm just a security guard, I also have human rights. You can't accuse me unjustly!"

"I ask you to release me immediately and I have to go back to work."

Work?

Unjustly accused?

Looking at Xie Shi'an who was still resisting, Chen Yan smiled.

"Xie Shi'an, do you really think you did it perfectly and didn't leave any evidence?"

"ignorance!"

"Do you know why we judged that Wang Luyao did not commit suicide?"

"Do you think that after you stun Wang Luyao with ether, put her on top of you, and then use Wang Luyao's right hand to hold a knife to hurt yourself, you won't leave any traces?"

"wrong!"

"Xie Shi'an, although you planned this carefully, you didn't know that marks will appear on the body after death. All the buttons of the shirt you wore that day left traces on Wang Luyao's back!"

"Xie Shi'an, we have now sent people to your residence to search. The clothes you wore that day will be found soon."

"Also, do you think you didn't leave any traces when you escaped through the window?"

"You don't know that the third floor of Wang Luyao's house is being renovated. Just two days before you killed Wang Luyao, the plastic steel windows downstairs of her house had just been replaced."

Snap!

Chen Yan took a photo on the table: "Xie Shi'an!"

"Do you see what this is?!"

At this moment, Xie Shi'an was sweating profusely.

When Chen Yan mentioned the traces of buttons inside Wang Luyao's body, Xie Shi'an had already started to become restless.

When Chen Yan said that he had sent people to search Xie Shi'an's residence, Xie Shi'an's pupils shrank rapidly and uncontrollably.
