Daming quickly sent over the processed surveillance video.

The specially processed surveillance video will not be blurred after being enlarged, and it will be considered clear.

The surveillance camera failed to capture the whole body of the girl, only a small part of it. The girl was walking and playing with her mobile phone. As she walked, she came to a wooden board.

That piece of wood was laid on the ground during work at the construction site to prevent scratches on the floor.

At this moment, she stiffened suddenly.

The high-voltage electricity instantly blinded her, causing her to be reflected in a distorted shadow under the street lamp.

Soon she fell to the ground and died. Only one hand could be seen in the screen. The point source should not have been removed. The blackened hand on the ground was still curled up...

After a while, it was almost impossible to tell that it was a human hand.

Su Hewen's hair stood on end: "It's too scary..."

Su Bao stared at the surveillance camera and asked, "Is it gone?"

Mu Guifan said: "Keep watching."

About five minutes later, another arm appeared in the surveillance screen - the reason why it was one arm was because the surveillance camera failed to capture the entire scene and only captured a small half of the scene of the incident.

It was ignored when checking the surveillance before because this part was too far away, too small and too blurry. It blended in with the shadow of the dancing trees. If you didn't look carefully, you would definitely think it was the shadow of the branches.

The man seemed to be frightened. He took a few steps back and sat down on the ground.

But soon the girl's electro-coated arm was dragged out of the frame, and the surveillance video disappeared.

Su Bao was stunned: "I still don't know who he is..."

Mu Guifan clicked on another video: "Continue watching."

This is the surveillance inside the mall.

The direction the surveillance camera is facing is the direction of the bathroom on the first floor. Going out from this direction is the back door reported by netizens.

This surveillance picture is from the morning when there are many people.

In the picture, a worker-looking man wearing an orange vest came out carrying two tool bags. He walked in a hurry and left quickly.

Hanhan was confused: "Nothing unusual!"

Mu Guifan nodded: "Most people won't find anything unusual. First, there are maintenance workers in the mall, which is normal. Second, the two bags in the worker's hands are bags for tools, which is normal.

Third, a complete corpse cannot fit into two bags, so no one will think that these two bags contain one person. Fourth, the weight of the bags he is carrying is about the same as the weight of carrying tools. If he is carrying

It's impossible to walk so easily while holding a corpse."

Therefore, when checking monitoring in the early stage, this worker was automatically skipped.

Around noon in the video, the workers returned to the scene again.

"Pay attention. Although the two bags he is carrying are bulging this time, they are very relaxed."

Su Hewen nodded: "It feels weightless."

Around the time of getting off work in the afternoon, the workers appeared again carrying two bags. This time the bags were heavy.

The monitoring of this screen is over.

Hanhan: "So?"

Su Zixi crossed her arms, looked up from her notes, and said speechlessly: "I usually tell you to study more, but you have to go herd the cows."

Da Touhan: "??"

She didn’t herd the cows!

Mu Guifan said: "When he came out with the bag for the first time, the worker lowered his head and couldn't see his expression, but you could tell that he was a little uncomfortable."

Hanhan: "Oh..." It's not very clear.

Su Bao nodded: "Yeah."

Da Touhan was suspicious: "You really see that it's unnatural?"

Su Bao pointed at the surveillance camera: "He raised his hand a little, as if he wanted to carry it but didn't dare. The other hand was lifted, but the fist holding the strap was clenched very tightly."

Mu Guifan nodded in praise, she was indeed his daughter.

"There is also the last video, surveillance one kilometer away from the incident location."

Mu Guifan clicked on the last surveillance video.

This is a surveillance video from the roadside. There are several large-sized classified trash cans placed on the roadside. There are some construction waste piled next to the trash can, including a dark red wooden board about 50*50cm.

"See this board?" He pointed at the screen and paused.

Su Bao nodded: "Yeah! I've been to my fifth uncle's construction site before, and it looks a bit like the wooden boards on the elevator."

Mu Guifan nodded: "This kind of wooden board is very thin. If it is such a small piece, it will be easily blown away if the wind is strong."

He reversed the video and the surveillance camera could see the entire street in the direction of the trash can.

The wind was really strong that night, the big trees were swaying, and several mineral water bottles were rolling quickly on the ground.

At this time, a piece of wood appeared on the surveillance screen. It didn't fly as fast as a mineral water bottle, but after several rolls, it quickly reached the roadside and got stuck on the road railing.

In the morning, a sanitation worker picked up the board and walked to the trash can. Since the board was a little bigger than the trash can, he put the board next to the trash can.

Fast forward in the video, the mall over the trash can happened to be being renovated by a shop, so they took out a few pieces of foam board, and the construction waste in the snakeskin bags came out and were piled next to the trash can.

Then the garbage truck came and collected all the garbage.

Da Touhan asked again: "So?"

Su Bao looked at her and sighed like a young adult: "Sister Hanhan, your eyesight is not good!"

"When that board was flying just now, there were burnt marks on it!"

Hanhan: "So?"

Su Zixi took the book and patted her on the head: "Go and herd the cows."

Hanhan touched her head. What happened to her? The board was burnt. What does it have to do with the girl who was shocked by high-voltage electricity?

Su Hewen said: "Arc discharge will occur when high-voltage electric shock occurs. The high temperature generated by the arc will cause, as well as the thermal effect of the current. According to Joule's law p=u^2÷r, assuming the voltage is..."

Hanhan: "..." I won't listen, I won't listen!

Mu Guifan: "Well, to put it simply, high-voltage electricity burns people. When burned, it will naturally leave burnt marks."

Hanhan suddenly realized: "So the burnt marks on this board are the burnt marks left by the girl?"

Mu Guifan nodded in praise: "This guy can still be saved."

Su Bao covered his mouth and snickered.

Mu Guifan paused the video on one screen.

When the sanitation worker picked up the board, the burnt side was facing the outside. It could be seen that the board was almost burned through, and there was a thin strip shape extending from the center.

"This is where the arm is burned."

Hanhan: Got it! It’s creepy!

"That is to say... the girl happened to step on this wooden board, and was electrocuted... and then burned, and the wooden board was also burnt... and then the wooden board was blown by the wind to a trash can one kilometer away, and was taken away by a garbage truck.

…”

Da Touhan looked dull and suddenly felt scared.

Su He asked and then realized the reason why she had been calm all the time. It turned out that she was too stupid and didn't want to understand...

Su Bao shook his head and asked, "But I don't understand. Isn't the wooden board non-conductive?"

Mu Guifan said: "Did Tangtang say in her self-report that she stepped on something that looked like a nail?"

The probability of stepping on a nail to conduct electricity is relatively small.

But if you step on the middle of the two boards, the probability of being scorched by high-voltage electricity is relatively high.

"It's probably two boards that were put together, and there were nails on the edges of the board... The specific situation depends on the worker at the time."

This board flew a kilometer away and the other boards should have been processed.

There are also several large classification trash cans beside the flower bed on site, which are also in the blind spot of surveillance. It is difficult to determine whether another board has been thrown away or taken away.
