I am Detective Wu Nan

Feng stopped talking, touched his nose and walked away, looking like he was thinking about life!

He was not hit by Wu Nan, but Wu Nan just said that the last, the last, and the last person who pursued Wu Xinyan seemed too miserable! This forced him to think seriously...

Quiet!

Wu Nan continued to watch the surveillance.

It was only a dozen minutes later that Chen Ai came back and directed Gu Feng to do this and that.

Chen Ai was the person in charge of the archives room, and Gu Feng was just a clerk in the archives room.

They were busy with theirs, and Wu Nan watched his own.

In this way, it took less than two hours.

Wu Nan had already watched all the surveillance once, and he was watching it for the second time. After only watching for more than ten minutes, he tapped the keyboard, paused the screen, enlarged a certain screen, and then chose to print.

The printer was next to it.

Wu Nan also pulled out an unused A4 paper from the printer, found a pen on the table, and wrote something.

The printer squeaked and printed it immediately.

Wu Nan took out the printed paper. It was the surveillance footage at the entrance of the second north gate of the park. There were many people in the picture. Some were sitting by the flower bed on one side of the entrance and chatting. Some were holding huge brushes and writing on the stone slabs with water. There was also a group of old ladies in colorful clothes standing at the entrance discussing something. They were probably waiting for people to go in and dance square dance together.

This was just a normal picture of the park. There were men, women, young and old, with more elderly people and children.

Wu Nan looked at it and took up a pen to draw a circle on it.

He circled the head of a young man. This young man, who was about 20 years old, stood near the bus stop at the entrance of the park, with his hands on his shoulders, and he didn't know what he was looking at.

Wu Nan circled him and then wrote the word"thief" below.

He felt so bored!

He was looking for clues about the missing girl, but since he had found the thief, it didn't seem to delay anything to point it out. What if it was a large gang? If so, Wu Nan would definitely gain kindness points by catching them.

Wu Nan circled two more people on the paper and wrote the word"accomplice".

Then he put the paper aside and continued to watch the surveillance.

A few minutes later.

The printer sounded again...

There are really a lot of thieves in places like parks. Of course, this also depends on the location and environment, and has a lot to do with the size of the park and the flow of people. Xujiahui Park is one of those particularly large parks with a lot of people. It is not an exaggeration to say that there are thieves every day. It’s just that thieves go there every day, but they may not be able to find the most suitable opportunity to commit a crime every day.

Wu Nan also heard that the black swans raised in Huijin Lake in Xujiahui Park were stolen... After the case was solved, it was said that the guy stole the black swan and stewed radishes.

At around eleven o'clock in the morning, Wu Nan checked the surveillance and had finished watching it.

Buzz, ding, ding, ding...

Wu Nan's cell phone rang.

"Hello, sister."Wu Nan said

"I won't look for you anymore. I'm outside. You can go to the cafeteria to have lunch by yourself.……"Wu Xinyan said that she and Zhao Chenglong should have visited the area near Xujiahui Park, and she didn't know how many people went there.

"Okay, I got it, sister." Wu Nan agreed and hung up the phone.

Without the mood to eat lunch, Wu Nan started watching the surveillance again, for the third time...

Actually, he watched it repeatedly, first because he was afraid that he would miss some details, and second, watching it repeatedly would deepen his impression. He wanted to remember everyone! Every single one! As long as they appeared in the surveillance video, it didn't matter how deep the memory was, at least seeing it again would help him recall it.

"Xiaonan, your sister hasn't come yet, come on, I'll take you to dinner." Chen Ai came over from the"warehouse" and said

"I'll eat later, I haven't finished watching yet."Wu Nan replied

"Do you want me to pack it for you?……"

"No, thank you, big sister. It's not a bother."

"This child……"

"Yes, big sister, did Uncle Zhao only take back the surveillance cameras of the park yesterday?"Wu Nan turned his head and suddenly asked,"Are there any surveillance cameras at the intersections of the main roads around the park?……"

""Is there any... Xiao Gu, can you look for it?" Chen Ai was still unsure, so she turned around and asked Gu Feng inside.

"Yes, some……"Gu Feng's voice came from inside.

Soon, Gu Feng brought another USB flash drive. There was a label on the USB cord with a number written on it.

There was more than one USB port on the computer host, so Wu Nan directly plugged this USB in... Traffic surveillance around the park is also very important, because the park surveillance is not comprehensive, and although the traffic surveillance is not facing the park, it can just capture the places around the park that are not the gates. If someone walks out of the small path with a little girl in his arms, the traffic surveillance may be able to capture it.

But now it is certain that the traffic surveillance must not have captured such a similar scene.

Because the Criminal Investigation Corps has already watched these surveillances and found nothing.

But this does not mean that there must be no clues!

Chen Ai and Gu Feng both went to eat. Normally, the archives room should be locked at noon, but today Wu Nan was there, so it was not locked. He was very relieved about Wu Nan and the others.

Wu Nan began to look at the traffic surveillance around the park.

He only needed to look at a specific time period, from 12:00 to 1:00 yesterday afternoon, because the girl Pan Yingying was lost during this time period!

The suspect must have taken Pan Yingying away from the park quickly.

It is very unlikely that he hid first, otherwise he would not have had the chance to take Pan Yingying away from the park.

Because there were too many people in the park, the old lady would find her granddaughter missing and start looking for her, which would alert everyone...

Xujiahui Park is roughly a quadrilateral, very irregular, with Hengshan Road to the northwest, Tianping Road to the southwest, Zhaojiabang Road to the southeast, and Wanping Road to the northeast.

These four roads form an irregular quadrilateral, surrounding���Jiahui Park.

Four roads form four intersections, and each intersection has at least two useful surveillance cameras. For example, at the intersection of Zhaojiabang Road and Wanping Road, there must be a surveillance camera shooting Zhaojiabing Road, and a surveillance camera facing Wanping Road. So there are two useful surveillance cameras at each intersection, and there are eight surveillance cameras that need to be watched at four intersections.

Wu Nan looked very quickly!

There are only eight surveillance cameras, and he only watched the ones from 12:00 to 1:00 noon yesterday!

He imported all the files into the split-screen player and watched the eight surveillance images at the same time!

10 times fast forward!

After just three minutes.

Snap!

Wu Nan knocked heavily on the keyboard to pause the picture!

Then he clicked on one of the surveillance images to enlarge it.

He looked at the picture on the monitor, which showed a silver-gray commercial vehicle.

Looking at it, his brows gradually frowned.

He blinked his eyes, as if he was still recalling something at the same time. _To read the ununderlined version of the novel, please download Fulu
