Chapter 45： confusing

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, this guy was still confused.

Dumbfounded and confused: "Old man, don't be kidding me, I've changed my mind a long time ago, don't use that thing to scare me..."

Gah!

Immediately afterwards, Zhang Jun, who slowly opened his eyes, was frightened and shivered.

"Politics...government...I"

"I am what I am!" Liang Xu is an old hand 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 the last time he came out, he has been working on the construction site honestly, and he has not done anything inappropriate.

Could it be that Sister Zhang, who hooked up with cooking, got a high profile?

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

Liang Xu: "..."

You kid thought it was inside.

"Okay, since you don't 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's expression without moving.

"My lord Diqingtian, I really didn't go anywhere last night."

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

Zhang Jun was so anxious that he burst into tears.

He heard about the murder in the morning.

Now that he is arrested, he must be involved in this case.

However, the conscience of heaven and earth, he Zhang Laosan stealing a battery car is fine, killing people...

He really dared not.

"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, in Zhang Jun, Li Hong only saw nervousness and fear.

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

"Zhang Jun's expression is very tense, and his muscles are naturally tense. When speaking, although there are many movements on his hands, there is no regularity, due to emergency tension..."

Chen Yan has the blessing of visual gene lock in this regard, and the analysis is more careful.

"At first glance, Zhang Jun didn't lie!"

No lie, this is Chen Yan's judgment.

Most importantly, there was no Zhang Jun's body odor at the scene.

Li Hong nodded, agreeing with Chen Yan's opinion.

However, whether Zhang Jun lied or not is not what Li Hong and Chen Yan said.

The deceased has his body fluids in his body, which is the strongest evidence.

If Zhang Jun didn't 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, the seven people in Zhang Jun's dormitory were also being questioned.

"We did drink yesterday. Mr. Zhang drank almost a bottle of white wine, and he drank too much."

"We went back at ten o'clock yesterday, and everyone drank a lot. Mr. Zhang didn't drink the most, but he was basically drunk. After going back at ten o'clock, I fell asleep..."

"He? Zhang Laosan can drink me with that little amount of alcohol? I'll give him a bottle and get down on the ground..."

……

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

There was surveillance in that place, and the eight people did go back after 10 o'clock, and Mr. Zhang drank almost a bottle of white wine.

As for the strangle marks on the neck of the deceased, Chen Yan and the others also compared them.

The traces are of the same size.

Zhang Jun... was temporarily detained.

Conference room.

All the investigators frowned.

Originally thought that the murderer had been found, and the evidence chain at the scene was consistent, so it could be concluded that Zhang Jun committed the crime.

However, his alibi...

Can a drunkard who drinks a bottle of liquor violate others and kill people?

Also, was he still wearing gloves to commit the crime?

Finally, after he violated the deceased, why did he scratch the body of the deceased?

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

Then why leave a neck revealing the cause of death, and an eyeball?

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

When two people had a relationship, especially if the deceased was reluctant, how could Zhang Jun leave no dander or hair on the deceased?

Could it be that the other party will spread a layer of plastic?

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

However, the deceased did not have Zhang Jun's dandruff tissue, only body fluids.

I can't explain it clearly, I can't explain a lot of things.

There is another woman's footprint on the second floor, who is the other?

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

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

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

Um?

Chen Yan's spirit was slightly lifted: "What did you find?"

"The deceased's going out behavior is more regular." Wang Gang projected the video he read on the screen.

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

"Among them, the clothes on Tuesday are more delicate and beautiful, but on Thursday and Friday, they are very casual, usually in casual clothes or pajamas to go out."

"Every time I go out, except for not going home on Tuesday night, sometimes I 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."

a year?

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

It was Monday!

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

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

Wang Gang paused: "But every Thursday and Friday, Qin Xiaoyu doesn't go out of school."

"Didn't go out of school?"

"Yes," Wang Gang opened another video: "This is the surveillance video at the entrance of the No. 3 teaching building of the Art College. Qin Xiaoyu comes to this teaching building every time."

Teaching building?

Everyone was slightly surprised.

Going to the teaching building in the middle of the night?

study?

"Did the surveillance video of the teaching building capture which classroom Qin Xiaoyu went to?"

Chen Yan seemed to have a guess.

"802!"

Classroom 802?

Chen Yan turned back suddenly and looked at a name on the case analysis board.

Jia Xinyi!

Jia Xinyi's studio is located in classroom 802 of the No. 3 teaching building!

A female college student has to go to her professor's studio at a fixed time every week, and it is after 10 pm.

to do what?

Learn to draw?

Give me a break.

"Wang Gang, do you have any clues about the chat software of the deceased?"

When Wang Gang heard Chen Yan's words, he was stunned for a moment and handed a stack of paper: "Captain, this is the WeChat chat record that the deceased used before his death. The other party didn't use the QQ software very much, and there was no information for the past two years."

"I've read all of them, even the chat records with classmates and family members, and there are no abnormal clues."

No clues?

boom!

Chen Yan was thinking, and the office door was opened again.

It is Luan Ping.

"Captain, Team Chen," Luan Ping saw that everyone was there, and quickly reported, "The whereabouts of Liu Jingting and Jia Xinyi have come out last night!"
