Let You Catch The Thief, You Broke The Serial Murder Case?

Bac Ninh Branch Criminal Investigation Team Office.

Xiong Zhuangshi brought some portfolios and a USB flash drive, all of which were placed in the middle of the desk where Lin Nan and Li Yanran were connected.

"The two of you, let's take a look! This is a case that has not been solved in recent years. You should study it to see if there are any missing clues."

"Let's see which case is of interest and our team will choose one to investigate."

Li Yanran clenched her fist full of energy and said, "Okay!"

"Xiao Linzi, this time we will compare to see who can find clues and breakthroughs from the inside first."

"Haha! Boring! No comparison!"

Lin Nan refused expressionlessly.

Pick up the thermos, drink tea, and shake your head.

The three movements were done in one go without hesitation.

pity.

Li Yanran didn't care about Lin Nan's rejection, just like she didn't hear it.

Still full of energy, he said: "Okay! The 1389th duel, the official start!"

Lin Nan: "..."

Why is Li Yanran such a dead girl?

Will you be sitting right at your desk facing each other?

His desk is also connected to Li Yanran's desk.

so close!

See you when you look up!

In the future, this kind of trouble will definitely happen every day.

so troublesome!

Lin Nan opened a portfolio and began to look through the case files.

903 Disappearances.

3 years ago on September 3rd.

Linhai High School, Beining District, Longjiang City.

A 17-year-old high school girl named Sun Mengmeng.

After school at noon, when passing a pedestrian street near the school, he suddenly disappeared mysteriously.

The only relevant clues are the surveillance footage of Sun Mengmeng walking in the pedestrian street and hanging out in the store before she disappeared, but she never appeared again after that.

Even in all the surveillance footage in the vicinity, no trace of her was ever found.

Live without people, dead without corpses.

Sun Mengmeng before her disappearance.

There was no suicide or any other abnormal reaction, nor did he suffer any blows.

It's just that my memory is not very good, I have mixed up some things, and my curiosity is stronger than before.

Lin Nan stared at the photo of Sun Mengmeng on the file.

A very innocent little girl with a sweet smile on her face.

Pity.

Three years have passed since the disappearance.

Sun Mengmeng was probably afraid that she had already suffered an accident.

The age like a flower can only exist in the photo forever.

In this portfolio, in addition to Sun Mengmeng's relevant information, there is also information about her parents.

Father: Sun Long, he had a car accident thirteen years ago.

Mother: Song Kexin, opened a small supermarket in the neighborhood near Linhai Middle School.

Human tragedy!

The white-haired person sends the black-haired person!

Lin Nan picked up the USB flash drive, inserted it into the office computer, and began to prepare to see if there were any clues in the surveillance.

Mouse double click.

Open the video material titled 903 Missing Cases Missing Person Video.

Video starts.

Lin Mengmeng's figure appeared.

Walking in the main road of the pedestrian street in a school uniform.

Nothing unusual, just very curious, looking around from time to time, occasionally entering a store, and reappearing after a while.

After about two minutes.

Lin Mengmeng figured out where the camera could detect.

After three seconds.

Video shot switching.

There was a video of Lin Mengmeng entering a store. Like a normal little girl, she picked something, looked at it, and then left.

Immediately followed by another store, still the same content, look at things, and leave.

…

This spliced ​​video of the missing person lasts about ten minutes.

It didn't take long, but nothing unusual could be seen.

Lin Mengmeng's expression was not abnormal at all, just like a normal little girl shopping.

There is no abnormal situation in every store, such as bookstore, flower shop, trinket shop, etc.

Lin Nan pondered for a long time, but found nothing unusual.

From the current point of view, it should not be Lin Mengmeng's own problem, but other factors.

So what is this other factor?

In the documents of the disappearance of 903 Pedestrian Street, there are some other related video videos.

According to the annotation of each video.

There are two videos in it.

It is the complete video data of the entrance and exit of the pedestrian street for 24 hours on September 3.

Besides.

There are also video materials of 18 businesses in the pedestrian street, all of which are indoor videos, and they are also all day on September 3.

Because in the video just now, Lin Nan didn't catch the clue.

So he felt that watching these complete videos might be rewarding.

at the same time.

Li Yanran, who was sitting at the opposite desk, had gold stars in her eyes.

In these nearly twenty minutes, she opened several portfolios.

It's all unsolved cases with no beginning and no end.

Thinking about it so much that my brain is going to explode, but there is no gain at all. *
