The professional quality of the male protagonist

"Can you find out who changed it?" Li Yancheng asked.

Old man Li and the others must have checked the surveillance video before, but when old man Li checked, he didn't find any useful clues. He didn't expect to change the surveillance video.

"I'm not sure yet." Liao Qun shook his head, "The surveillance video was said to have been altered, rather it was cut and replaced with other things. It is not so easy to restore, and the restoration The probability is very low.”

"When is the approximate time?" Li Yancheng asked again.

"Within two hours before the second case happened." Liao Qun said.

If it was within a few hours before the second case, then it is likely to be the video of the victim in the second case when he went home.

"Which section of the road was changed?" Li Yancheng asked again.

There are different canteens at the front and back doors of this school. Some of the canteens have surveillance video installed and some don’t. The surveillance videos they found are basically provided by the canteen. Most of the shooting locations are not facing the main entrance but facing the fence.

Liao Qun took the map and sketched a rough orientation on it.That place was near the wall not far from the side door, and the victim's body was found near there.

"Is it possible that the victim was discovered immediately after climbing in from the fence, and then he was killed?" Ye Kai said.

The place where the body was found was too far from the place where the snowman found it. The victim was killed on the opposite side of this surveillance video wall. If the murderer killed someone and threw the body here, it would be too redundant to turn back.

"It's possible. But if the murderer did it in this place, what tools would he use?" Li Si said, "When we went to the girls' dormitory to investigate, we learned that the victim didn't go back to the dormitory that day, so he definitely didn't. The dormitory was killed again, and I also paid attention to the situation in the dormitory when I went there, there is almost no private sex, the place is public, if you kill someone and go back, there is no way to clean up the blood on your body."

"Based on what you're saying, it's impossible for the murderer to be a person in the dormitory?" Zhang Xuan said, "If the covered video under this surveillance video can prove that the victim once climbed over the wall to enter from there, is it possible that it was because of the surveillance video?" He was photographed, so he was covered?"

These two guesses are similar, but the point is to see if it can be recovered.

Several people looked at Liao Qun at the side.I thought Liao Qun would give them a positive answer, but Liao Qun shrugged, "It's hard to say."

Not only the rest of the people, even Li Yan was a little surprised.In my impression, Liao Qun can do a lot of things, and most of the time he can do it. If Liao Qun says that he can't recover, he probably can't find anyone to help him, but it is difficult to answer with an uncertain answer like now Very few.

"The person who modified this video used a very clever technique. On the way, I separated the video that was overlaid on it. I don't know if the video below is still left, but I can try to find this person." Liao Qun said.

People who can achieve Liao Qun's skills are usually known to Liao Qun. Even if you can't find the original video, you can start from the human side.

"You try to restore the video first, and if it doesn't work, then think of other ways. I'll go to the dormitory to have a look in the afternoon." Li Yancheng said.

to the dormitory?

Zhang Xuan froze for a moment.

He looked back at Li Yancheng, "Are you going to the girls' dormitory?"

Before Li Yancheng asked Zhang Xia and Li Si to go to the girls' dormitory to investigate and they didn't have any objections. After all, there is no problem with the two women going, but if Li Yancheng also goes, then the problem will be big!

"There are some things I want to know about." Li Yancheng said.

From entering this case to the present, the only relationship between the victim in the second case and the missing girl in the first case is three points in total. The first point is that they both study in this school, and the second The first point is that they all live in the female dormitory, and the third point is that they are friends.

Because the possibility of being killed by people from the same school is too low, it is possible because the dormitory building is not far away, because the possibility of being friends is the lowest.

"I'll go too." Zhang Xuan said.

"You guys are going to check the information on the section of the road covered by the previous surveillance video to see if there are any clues, and ask Oman to follow him to check if there are fingerprints or something." Li Yancheng said, he looked at Zhang with some puzzlement Xuan, Zhang Xuan is a little strange recently.

"I'll be with him." Li Si couldn't help but smile when he watched the interaction between Li Yancheng and Zhang Xuan. No one in the team except Li Si knew about the relationship between the two, even Ye Kai. I just thought the relationship between the two of them was good.

Seeing Li Sidu say that, Zhang Xuan's face turned red.

Turn your face away, Zhang Xuan pretended to lower his head to tidy up.

Liao Qun rolled his eyes angrily. The others were either busy eating instant noodles or reading materials, so they didn't notice Liao Qun's actions.

After eating, everyone rested for a while, but no one wanted to sleep. The longer this matter dragged on, the worse it would be for them, the pressure would be great, and the liver would be hurt.

"By the way, how is old man Li's investigation going?" Hu Xingfan asked.

Hu Xingfan couldn't stand the cold weather, and couldn't help rubbing his hands when he sat in the room.

He Xiuwen is not much better than him, his hands and face are red, He Xiuwen said: "I have checked all the things that can be checked in a short time, and the rest are probably impossible. ..."

If it is □□, then it is not so easy to check.If you really want to check, you have to give him an approximate range, or the target, so that he can check.

While several people were talking, a person pushed the door in. When he entered, it was still snowing outside, and when he opened the door, the heating inside the room suddenly became cold.

"Hey, you are all here!" Oman, who had just entered the door, was very happy to see that everyone was there. He was wearing a heavy down jacket, wrapped like a bear.

The others hurriedly got up and put on their clothes, while Aman took off his shirt and walked in front of everyone, "Look at this autopsy report, it was just released, I hope you are satisfied."

Hearing what Oman said, everyone immediately gathered around. Seeing Oman like this, they knew that he must have made progress, so they dared to speak like that.

Before coming here, old man Li had given them an autopsy report, and they all knew about the victim's autopsy information.

But Oman's report is much more detailed than the previous report, and the focus is more in line with their wishes.

The previous report was very formulaic, and all the materials were written as usual, but there was little in-depth information.

Aman is a partner who has worked with Li Yancheng for many years, so he knows very well what the appraisal report that Li Yancheng needs looks like. He focused on checking the wound marks and some other symptoms of the victim. Compared with the previous report, it was not so detailed. But it is much more useful.

There was only one copy of the information, and several people spread it to read it, and those who were waiting behind couldn't wait.

Seeing this, Aman simply sat down and said by himself: "The victim was Li Yancheng when he died. The specific time of death should be around 11:1 to [-]:[-] in the middle of the night. His wounds were caused after he died, and there are many places. There are traces of frostbite." Aman said.

"Frostbite?" Li Yancheng grasped the word keenly.

"That's right, most of the wounds on the victim's body showed signs of frostbite. The weapon used by the murderer should have been exposed to the ice and snow, and the temperature was extremely low," Oman said.

"And I carefully compared the wounds on the victim's body. The traces of the wounds are very strange. Although they were cut by sharp objects, the cuts are very uneven." Aman said.

"Ice?" Li Yancheng said, the temperature was very low and his brother was very uneven, the first thing Li Yancheng thought of was the thin ice cubes that were frozen into ice.

Ice is a very interesting thing. When its density is not high, it can be very brittle, so it will be broken together. When its density reaches a certain density, its hardness will be very high, and it can even be broken. Use as a hammer.

"That's right, that's what I guessed too." Oman said.

After hearing the words, everyone looked clear.

If so, it's no wonder they couldn't find the murder weapon before.

"Bing..." Xie Wenyuan frowned. Bing is too random. If the other party's murder weapon is really Bing, it must not have been planned in advance. Could this be a random killing?

But now one is doing one death, isn't it too coincidental to kill people at will?

The rest of the people Xie Wenyuan thought of also thought of it later, if they kill people at will, why should the other party look like a snowman?

After much deliberation, they couldn't get an answer, and in the end, several people continued to investigate as planned.

If the other party killed because of revenge, then there must be some necessary connection between the two victims.

As for killing at will?Investigate later.

"Have you checked the situation of the first victim and the second victim's house?" Li Yancheng asked again. There was still snow outside the house, and the snow was getting bigger and bigger. Because of the limitation of the geographical environment, they couldn't go out to visit at all. , can only keep looking at the information in the house.

"Old man Li probably went to ask about it, but didn't investigate carefully, so he shouldn't be hiding anything. I've seen the victim's family members, and ordinary people haven't found any enemies so far."

"If the clue is not at home or at school, the only thing left is the dormitory." Li Sidao.

"Haven't you already checked the dormitories?" Ye Zhong asked.

"Little friend, the world of women, don't think too simply. Although the school is full of half-grown brats, they are all members of the group. No matter how many times you check, the result of each check is not the same. Same." Zhang Xia said.

Li Si was deeply touched by her words, and kept nodding when she spoke.
