"First of all, it's the lie that Guan Lan told just now, she said that she didn't know Peng Yitong well.

This is a typical psychological reaction after a partnership commits a crime, afraid of exposing the cooperative relationship, and also afraid that one party will be arrested and the other party will be implicated, so they often say that they are not familiar with each other and do not know each other. ”

"You mean, Peng Yitong set a fire in the dormitory, and Guan Lan - one of the details she said should be reasonable, that is, after the fire, Li Nana's first reaction was to close the door to cover up the accident - so she had the opportunity to lock the door outside without noticing."

"That's right."

"That ......" Wu Duan sent a photo of the two girls to the criminal police who were visiting the lock shop, and sent a message to tell them that they must ask if the person who bought the lock was among the two people.

After explaining this, Wu Duan continued: "Why can't it be an unintentional fire? - Just like Guan Lan said, Li Nana and the two of them played with fire and set themselves on fire. ”

"The act of buying locks and buying locks in advance shows that this is a premeditated crime, and the purpose is to lock two people in the house and burn them to death.

How can such a premeditated crime pin the success or failure of key links on accidental incidents?

It must have been intentional arson! ”

Yan Sixian asked again: "Is the lock handed over to the physical evidence department?" How so? ”

"How else can you say that the heat is burning, and you still expect to find a half-fingerprint? There was no trace of anything. ”

Yan Sixian thought for a moment and continued: "The key, the key to that lock is useless, and if you leave it, it's a handle."

The murderer will definitely dispose of the key, what do you think she will do? ”

"Metal is not destroyed, it can only be thrown away...... But...... Is it possible that it was thrown away a long time ago? ”

"It's unlikely, at least you have to keep one, in case the lock is accidentally locked before use, you have to open it." Then you say...... Will there be traces such as fingerprints on the keys? ”

"Possibly."

Yan Sixian sighed, "It's a pity that there are too few clues, and this kind of laborious clue that is not necessarily pleasing must be found." ”

"It's good to get used to it, if the clues are all directly under your nose, is it still called a criminal investigation?" Wu Duan said: "Since the fire started last night, Guan Lan and Peng Yitong have never been out of school, so ...... All the trash cans in the school, and the trash that has been cleaned out...... I'll take someone to search. ”

"The mentality is not bad," Yan Sixian said, "Then ...... It's hard work to help the police. ”

"What about you?" Wu Duan asked, "What are your next arrangements?" ”

"Let's talk to Peng Yitong again, and I want to take a look at the monitoring of the school on the night of the fire."

……

Feng Xiaoxiang not only provided the two with surveillance within the school, but also packed another video folder.

"What's this?" Wu Duan asked.

"The students took videos and pictures at the time, and I packed them together from the Internet last night. The main reason is that the camera angle of the school is not very good, and it is difficult to find anything, so it is recommended that you start here. ”

"Great! Smile and do things thoughtfully. ”

Feng Xiaoxiang was silent for three seconds, "Captain, I'll hang up the phone first if there's nothing to do." ”

When Yan Sixian heard it, he laughed out loud.

"In the eyes of hackers, there are only two kinds of people in the world, one is a fool, and the other is a hacker who is more powerful than himself.

You are clearly the latter, praised by fools...... Tut-tut, I'm embarrassed for Xiaoxiao. ”

"Get out!" Wu Duan said: "You can see through hackers who know how to use the power of the people?"

The power of the people is indeed strong, and in the compressed package, there are more than 30 videos and hundreds of photos.

It's a pity that the people's shooting level needs to be improved, some video images are shaky, and some are shot from strange angles.

After watching the three videos, Wu Duan frowned, and his face became very bad.

"It doesn't have to be like that, right? It's much worse than that. Yan Sixian looked accustomed to it.

"Dizzy 3D, like this since I was a child, when I see this shaky picture, I feel dizzy and nauseous and want to vomit."

"It's pathetic."

"It's okay, it's not inconvenient, at most, you can't play shooting games."

"Does watching a romantic action movie have an impact?"

"Huh?"

Wu Duan's jaw fell to the ground again.

Yan Sixian asked a serious question, if you just looked at his expression at this time, no one would have thought that he was asking such a question.

"I'm just pure...... Belch...... Out of theoretical curiosity, you don't want to answer it. ”

Wu Duan held a black line on his head and replied bluntly: "It doesn't matter."

"Poof...... You're ......."

"Stop! Watch the video for yourself, I went through the garbage. ”

"Hahaha, don't send ...... away"

Yan Sixian kept seeing the sunset, rubbing his eyes, dozing off, and habitually staring at the screen while pondering what takeout to eat.

He had already watched the video being played for the fourth time, and this time, a figure flashing in the corner of the video caught his idea.

It was a girl, wearing a school uniform and carrying a thermos, walking very fast. Yellow hair – not dyed yellow, but malnourished yellow.

Yan Sixian instantly came to his senses, sat up straight, retreated for ten seconds, stretched his neck and stared at the person who flashed by, and almost watched this extremely short video frame by frame.

Unfortunately, she never looked up.

Even if she didn't raise her head, based on her gait and posture, she could still be judged that she was Peng Yitong.

At the end of the video, Peng Yitong was photographed walking out of the dormitory building with a thermos, and before that, the 12-minute video focused on a smoking window, which was apparently 617 on fire.

Not only was the window smoking, but the night was already dark, and orange tongues of fire loomed in the window.

Bang –

There was an explosion, the windows were shattered, and the glass ballasts sprayed straight out.

The video shakes violently, and the person who shot the video can be felt to be backing away.

While retreating, he also said, "How many times?" Three times, right? Why do you still have an explosion? …… Groove Groove ...... Bombs in the dormitory?

No way! There's someone inside! …… Look! Look! …… Damn it! Did you get it? ……

Has anyone hit 119 with the grass? Hey, why don't we fight one? …… Forget it, someone must have beaten it, forget it......"

The photographer kept talking to the person next to him, and the picture shook so much that Yan Sixian couldn't see the person he was talking about.

But this video already illustrates an important point.

The time is not right!

According to Guan Lan's description, after Peng Yitong went out to fetch water, she first saw the whole process of Li Nana and Li Shuang playing with fire and self-immolation, and then went to the bathroom, where they stayed in the bathroom for about ten minutes, and someone found that it was on fire, and the people on the sixth floor began to run out.

Theoretically, Peng Yitong should have stayed away from the dormitory building before the fire spread, and according to her own account, she didn't know her dormitory was on fire until she returned from hot water.

The video shows that when Peng Yitong left the dormitory, the fire was already so big that it caused onlookers.

Yan Sixian wanted to call Wu Duan, but Wu Duan called first.

"The key was found! There is half a fingerprint on it! …… Comparison results...... The fingerprints are Guanlan, and you can start arresting people......"
