The arrest process went smoothly.

When Chen Yan and the others arrived at the construction site dormitory, this guy was sleeping with his head covered.

When the cold silver bracelet was put on Zhang Jun's wrist, the guy was still confused.

He was confused and confused: "Old man, don't be joking. I have changed my ways long ago. Don't scare me with that thing..."

Ga!

Immediately afterwards, Zhang Jun slowly opened his eyes, making him tremble.

"Government...government...me"

"What am I!" Liang Xu is a veteran at this.

"What is your name!"

"Zhang...Zhang Laosan."

"What's your real name?"

"Zhang...Zhang Jun."

"Do you know why I arrested you?"

Why?

Zhang Jun was obviously frightened, but since he came out last time, he has been working on the construction site honestly and has not done anything harmful.

Could it be that she hooked up with Sister Zhang who was cooking and was raped?

"Government...government, is my sleeping position...wrong?"

Liang Xu: "..."

You kid thought you were inside.

"Okay, since you don't want to say it, let's find a place to say it! Take it away!"

…

trial room.

Liang Xu was interrogating Zhang Jun, while Chen Yan and Li Hong were watching the surveillance video.

Chen Yan stared at Zhang Jun with a motionless expression.

"My dear Mr. Qingtian, I really didn't go anywhere last night."

"It rained last night. My roommates, Wang Laoba, and I went out for a drink. We didn't come back until after ten o'clock. I drank too much, so I went back to the dormitory and fell asleep. I was late for work this morning..."

Zhang Jun was so anxious that he burst into tears.

He heard about the murder case this morning.

If he is arrested now, he must be involved in this case.

However, due to the conscience of heaven and earth, Zhang Laosan can steal a battery car but kill people...

He really didn't dare.

"Team Chen, what do you think?"

Li Hong has also been observing Zhang Jun's expression, hand movements and body swings.

When people lie, they will subconsciously make some small movements, which are not obvious, but there are still traces to follow.

However, Li Hong only saw tension and fear in Zhang Jun.

Chen Yan naturally knew what Li Hong meant. As an old detective, although Li Hong may not have studied criminal psychology or criminal behavior, his eyes were very vicious.

"Zhang Jun's expression is very nervous, and all his muscles are naturally tense. When he speaks, although there are many movements on his hands, they are not regular. It is caused by emergency tension..."

Chen Yan has the blessing of visual gene lock in this aspect and analyzes it more carefully.

"Preliminarily, Zhang Jun did not lie!"

I'm not lying, this is Chen Yan's judgment.

The most critical point is that there was no body odor of Zhang Jun at the scene.

Li Hong nodded and agreed with Chen Yan's opinion.

However, whether Zhang Jun lied or not is not up to Li Hong and Chen Yan.

The presence of his body fluids in the body of the deceased is the strongest evidence.

If Zhang Jun did not commit the crime, how could there be Zhang Jun's body fluids in the body of the deceased?

While Liang Xu was interrogating Zhang Jun, seven people in Zhang Jun's dormitory were also being questioned.

"We did drink yesterday. Zhang Laosan drank almost a bottle of liquor, which is too much."

"We went back after ten o'clock yesterday. Everyone drank a lot. Zhang Laosan didn't drink the most, but he was basically drunk. After we went back after ten o'clock, I fell asleep..."

"With Zhang Laosan's drinking capacity, can he drink more than me? I'll do it for him after just one bottle..."

…

The confessions of the seven people were basically consistent, and Liang Xu also arranged for detectives to go to the night market on the street behind the school for verification.

There was surveillance in that place, and the eight people did go back after 10 o'clock, and Zhang Laosan did drink almost a bottle of liquor.

As for the pinch marks on the deceased's neck, Chen Yan and others also compared them.

The trace sizes match.

Zhang Jun... is temporarily detained.

In the conference room.

All the investigators were frowning.

I originally thought that I had found the murderer, and since the evidence at the scene was consistent, I could already conclude that it was Zhang Jun who committed the crime.

However, his alibi...

Can a drunkard who drank a bottle of liquor assault others and kill someone?

Also, was he still wearing gloves when he committed the crime?

Finally, after violating the deceased, why did he scratch the deceased's body?

Just to prevent the identity of the deceased from being exposed?

Then why is there a neck that reveals the cause of death, and an eyeball?

Most importantly, except for body fluids, there was no trace of Zhang Jun on the body of the deceased Qin Xiaoyu.

Two people had a relationship, especially if the deceased was unwilling. How could Zhang Jun not leave any dander or hair on the deceased's body?

Could it be that the other party has laid a layer of plastic?

Besides, even so, since there were bodily fluids in the body of the deceased, it means that Zhang Jun did not take safety measures.

However, there was no Zhang Jun's skin tissue in the body of the deceased, only body fluids.

I can’t explain clearly, I can’t explain many things clearly.

There are also footprints of another woman on the second floor. Who is that person?

But if it wasn't him, why would Zhang Jun's body fluids appear in the body of the deceased?

Just when everyone was at a loss what to do, Wang Gang came back.

"Team Chen, the surveillance video of the deceased Qin Xiaoyu's daily outings has been analyzed."

Um?

Chen Yan was slightly refreshed: "What did you find?"

"The deceased's outing behavior was relatively regular." Wang Gang projected the reviewed video onto the screen.

"I go out about three times a week, on Tuesday, Thursday and Friday, all after ten o'clock."

"Among them, Tuesdays are more sophisticated and beautifully dressed, but Thursdays and Fridays are very casual, usually wearing casual clothes or pajamas when going out."

"Every time I go out, except for Tuesday night, I sometimes go back to the dormitory on Thursday and Friday, and sometimes I don't go back to the dormitory."

Tuesday, Thursday and Friday?

"How long has this been going on?"

"Almost a year."

One year?

For a whole year, Qin Xiaoyu's activities were so regular, but why did he go out on the day of the incident?

That day was Monday!

"Every time she goes out, who picks her up?"

Wang Gang immediately opened a video: "Every Tuesday, a BMW sports car comes to pick up Qin Xiaoyu. We are verifying the owner's situation."
