Chapter 34 The clue ends here
In this video, it only took fifteen seconds from Zhang Yan's appearance to the moment she walked out of the surveillance screen.
This was while she was walking and talking on the phone.
If she kept walking at a normal speed, she would be able to complete this distance in ten seconds.
After all, the monitoring range at the entrance of a store is relatively small, which is about ten meters away.
Yu Dazhang watched the video over and over again, his eyes fixed on Zhang Yan's lip movements on the screen.
He has watched it for the fourth time, but still feels very strenuous.
It's too much for the eyes.
Compared with distinguishing expressions in the first video, the difficulty this time is twice as high.
It is necessary to carefully observe the mouth shape to interpret what Zhang Yan said.
If it were in a real scene, Yu Dazhang could easily capture the changes in the opponent's mouth shape with his extraordinary eyesight.
But there is nothing you can do when faced with surveillance video.
Pixels determine clarity, and it doesn’t matter how good your eyesight is.
Fortunately, the surveillance video can be watched repeatedly, and Zhang Yan only said two sentences in this video.
But it was these two sentences that Yu Dazhang read four times before he was sure.
The first sentence: "I don't listen, I don't listen, I don't want to hear what you say. If you do this again, I will never pay attention to you again."
After finishing these words, Zhang Yan in the screen paused for about seven seconds.
This means the person on the other end of the phone is talking.
Second sentence: "I said, I never thought about it that way. You misunderstood."
Something fishy~
Yu Dazhang had a hunch that the person Zhang Yan was talking to and the person who sent the message before were probably the same person.
Just the content of this conversation...
Under what circumstances could Zhang Yan say these words?
fall in love?
It's not like that, even if a couple quarrels, it's not about this.
The content of the first sentence was obviously that the other party said something Zhang Yan didn't want to hear, so she didn't hesitate to threaten the other party with breaking off the relationship to stop talking.
The second sentence points out that the other party has misunderstood her.
The relationship between these two people is unusual.
If they are not acquainted, there is no talk of breaking up the relationship at all.
There are too many misunderstandings that can arise between acquaintances.
The video is too short, it would be nice if I could say a few more words... Yu Dazhang has no clue for the time being.
"Go on to the next segment."
"Dazhang, please wait for a while." Lu Zhongxin couldn't help but asked:
"Did you notice anything in that video just now?"
"No." Yu Dazhang shook his head in denial.
He was really too lazy to explain.
I came here to find new clues, not to teach literacy classes.
What if Master and Qian Cheng asked me to teach them lip reading?
Isn't this causing trouble for yourself?
Besides, can anyone learn lip reading? It depends on talent.
First of all, you must have a gossipy heart.
"I didn't realize you had read it so many times." Lu Zhongxin said with dissatisfaction in his tone.
Just now he clearly saw Yu Dazhang stretching his neck and staring at the computer screen with his eyes wide open, his head almost touching it.
She looked like she was trying to see through Zhang Yan in the picture.
If there wasn't something that deeply attracted him, how could he act like this
"It's just because I didn't find it."
Yu Dazhang showed a natural expression:
"If I find something, do I still need to look at it so many times?"
This rhetorical question left Lu Zhongxin speechless.
It seems...there's nothing wrong with it.
Seeing that the two of them were no longer talking, the police comrade clicked on the next surveillance video. Yu Dazhang originally wanted to continue his lip translation work.
But in the following video, Zhang Yan did not make a phone call.
Instead, he moved 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. There was a difference of about three minutes between the two videos.
"Didn't any other surveillance cameras capture the victim between these two sections?" Yu Dazhang asked reluctantly.
"No." The policeman replied with certainty:
“The road section where the shop is located is relatively remote, and the nearby stores are all for rent.”
"Only two houses in the entire street are under surveillance. The other one is across the road and Zhang Yan cannot be photographed."
"I followed her route home to investigate. This is the closest surveillance to the upper section of the road."
"Definitely nothing was missed."
It can be seen that this comrade policeman investigated very carefully, otherwise he would not blurt out these details.
Check out the 16-9 book bar and see the correct version!
It seems that the lip translation work can only come to an end... Yu Dazhang only noticed Zhang Yan's unhappy face in this video.
It must be directly related to the previous phone call.
Other than that, no other abnormalities were found.
"Go ahead."
Next there were three videos of Zhang Yan on her way home. Yu Dazhang watched each video carefully, but found nothing special.
The last surveillance video was at the gate 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 Dazhang could ask, the police comrade on the side took the initiative to explain:
"I went to the scene and saw that the building she turned around is adjacent to the building where her home is located."
Yu Dazhang nodded slightly:
"So, she should have gone home directly."
At this point, the surveillance video has finished playing.
These videos completely record the whole process of Zhang Yan coming out of the school gate and going home.
Although the first two videos show her behaving a little unusually.
But judging from the entire journey home, she did not encounter any suspicious people or events.
In addition, Yu Dazhang also noticed that the community where Zhang Yan lives is an open community.
Usually, due to the lack of effective management and maintenance, it is common for such old communities to have no monitoring facilities.
Only supermarkets in the community will install cameras at the door to ensure safety.
At the same time, such a community does not have access control.
Both residents of the community and outsiders can come and go at will without any restrictions.
"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 shows her walking towards home.
Although she finally disappeared around the corner, Yu Dazhang was sure that she entered the house safely.
It was afternoon, and if there was an emergency in broad daylight, it would definitely attract others' attention.
Even if you don't dare to stop it, you will call 110 to call the police.
"The clues are cut off here." The police comrade looked very frustrated:
"I later checked the surveillance at various exits, even the surveillance at the community 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 has been busy working on the ending.
Then coming to the police station today means knowing the beginning of the matter.
What happened in the middle?
