Rebirth 2014: I, the King of Criminal Investigation

Chapter 34 The clue is broken here
In this video, it only took fifteen seconds from the time Zhang Yan appeared to the time she walked out of the surveillance screen.

This was while she was walking and talking on the phone.

If she maintained a normal walking speed, she would probably be able to complete this distance within ten seconds.

After all, the surveillance range at the door of a shop is relatively small, which is about ten meters.

Yu Dazhang watched the video over and over again, his eyes fixed on Zhang Yan's lip movements on the screen.

He had watched it for the fourth time and still found it very strenuous.

It's too tiring for the eyes.

Compared with the facial expressions in the first video, the difficulty this time has doubled.

You need to carefully observe the shape of her mouth to interpret what Zhang Yan said.

If it were in a real scene, Yu Dazhang could rely on his extraordinary eyesight to easily capture the changes in the other person's mouth shape.

But there is nothing we can do when faced with surveillance video.

Pixels determine clarity, and even the best eyesight won’t help.

Fortunately, the surveillance video can be watched repeatedly, and in this video, Zhang Yan only said two sentences.

But it was these two sentences that Yu Dazhang read four times before he was sure of.

The first sentence: "I don't want to listen, I don't want to listen, I don't want to hear you say this, if you do this again, I will never talk to you again."

After saying this, there was a pause of about seven seconds between Zhang Yan in the picture.

This means the person on the other end of the line is talking.

Second sentence: "I told you, I never thought of it that way, you misunderstood."

There is something strange~
Yu Dazhang had a hunch that the person Zhang Yan was talking to and the person who sent the message before were most likely the same person.

This is just the content of the conversation...

Under what circumstances could Zhang Yan say these words?
fall in love?
No, even if couples quarrel, it’s not like this.

The content of the first sentence clearly showed that the other party said something Zhang Yan didn't want to hear, so she threatened to break up the friendship with him to stop him from saying it again.

The second sentence points out that the other party has a misunderstanding of her.

The relationship between these two people is not ordinary.

If you are not familiar with each other, there is no question of breaking up.

There are too many misunderstandings that can arise between acquaintances.

The video is too short, it would be better if you could say a few more words... Yu Dazhang was at a loss for the time being.

"Go on to the next segment."

"Da Zhang, please wait a moment." Lu Zhongxin couldn't help but ask:
"Did you notice anything in that video just now?"

"No." Yu Dazhang shook his head in denial.

He was too lazy to explain.

I came here to find new clues, not to hold a literacy class.

What if Master and Qian Cheng asked me to teach them lip reading?
Isn't this causing trouble for yourself?

Besides, not everyone can learn lip reading; it depends on talent.

First of all, you have to have a gossipy heart.

"I didn't realize you had watched it so many times." Lu Zhongxin said with dissatisfaction in his tone.

Just now he clearly saw Yu Dazhang stretching his neck, staring at the computer screen with his eyes wide open, his head almost sticking to it.

It looked as if he wanted to see through Zhang Yan in the picture.

If there was nothing that attracted him deeply, how could he have done this?

“It’s because I didn’t find it.”

Yu Dazhang showed a matter-of-fact expression:
"If I discovered something, would I have to read it so many times?"

This rhetorical question left Lu Zhongxin speechless.

It seems...there's nothing wrong with it.

Seeing that the two stopped talking, the police officer clicked on the next surveillance video. Yu Dazhang wanted to continue his lip-reading translation work.

But in the next video, Zhang Yan did not make a phone call.

Instead, he walked forward at a normal pace and quickly disappeared from the surveillance screen.

The whole process lasted only eight seconds.

Yu Dazhang glanced at the time display in the upper right corner of the surveillance screen and found that there was a difference of about three minutes between the two videos.

"Are there no other surveillance cameras that captured the victim between these two sections of road?" Yu Dazhang asked unwillingly.

"No." The policeman answered with certainty:
"The shop is located in a remote area, and all the stores nearby are for rent."

"There are only two houses with surveillance cameras on the entire street. The other one is across the street and couldn't capture Zhang Yan."

"I followed the route she took home and this is the surveillance camera closest to the upper section of the road."

"There is definitely nothing missing."

It can be seen that this police officer conducted a very detailed investigation, otherwise he would not have blurted out these details.

It seems that the lip-reading translation work has to come to an end... Yu Dazhang only noticed that Zhang Yan looked unhappy in this video.

It must be directly related to the previous phone call.

Apart from this, no other abnormalities were found.

"continue."

There were three more videos of Zhang Yan on her way home. Yu Dazhang watched each one carefully, but did not find anything special.

The last surveillance video was taken at the entrance of Zhang Yan’s community.

Through this video, you can clearly see Zhang Yan walking into the community and finally disappearing around the corner of a residential building.

Before Da Zhang could ask, a police officer nearby took the initiative to explain:
"I went to the scene and saw that the building after she turned the corner was adjacent to the building where her home was."

Yu Dazhang nodded slightly:
"So, she should have gone straight home."

At this point, the surveillance video has been played.

These videos fully record the entire process of Zhang Yan leaving the school gate and returning home.

Although the first two videos show that her behavior is somewhat abnormal.

But judging from the entire journey home, she did not encounter any suspicious people or incidents.

In addition, Yu Dazhang also noticed that the community where Zhang Yan lived was an open community.

Generally speaking, it is common for such old communities to have no monitoring facilities due to lack of effective management and maintenance.

Only supermarkets within the community will install cameras at the door to ensure safety.

At the same time, there is no access control in such communities.

Both residents and outsiders can enter and exit the community freely without any restrictions.

"And that's all?"

Yu Dazhang couldn't help but frown:

"There's not a single video of her coming out?"

This is the key point of the whole thing!

The last image of Zhang Yan showed her walking towards home.

Although she finally disappeared around the corner, Yu Dazhang was sure that she returned home safely.

It was afternoon, and if something unexpected happened in broad daylight, it would definitely attract other people's attention.

Even if I don’t dare to stop it, I will call 110 to report it to the police.

"That's where the clue ends." The police officer looked very frustrated:
"I later checked the surveillance cameras at all exits, even the surveillance cameras at the neighborhood supermarket, but I didn't see her again."

Then Zhang Yan’s body appeared in Kong Lingjie’s rental house five days later...Yu Dazhang added in his heart.

If the previous task force had been busy preparing for the ending.

So coming to the police station today means knowing the beginning of the matter.

What happened in the middle?
