Once the psychological defense line is removed, the follow-up Q&A will be smooth and natural. (Chasing books on the new book network xinshuW· Com)

Yan Kuan, under the guidance of Shen Yan, naturally told him everything he knew about Huang Xu and Xu Pan'an.

He first received a call from Chen Ping on the morning of May 20 last Wednesday, when Chen Ping was terrified to find that his son's school uniform was covered in blood on the back.

After he found out, he immediately called Huang Xu and Xu Panan to the dean's office, but Yan Kuan did not lie about the condition of the two students, and when he asked the two students, they had lost their memories of the previous night.

At that time, Yan Kuan didn't know that there was a heinous and cruel case of corpse mutilation in CS City, and Yan Kuan was afraid that Huang Xu and Xu Panan had made some irreparable mistakes.

Although he was a teaching director, he was thinking that Xu Panan was his nephew, and he must hide this matter.

He knew that Xu Panan and Huang Xu were usually inseparable, so he called Huang Xu's father as soon as possible, and wanted Huang Lin to also confirm whether Huang Xu's school uniform also had blood stains. If anything, let him destroy the school uniform as well.

However, when Huang Lin called him back, the school uniform was clean, which made Yan Kuan even more worried, he was afraid that the mistake was made by Xu Panan alone, or Xu Panan was the main culprit.

It's a pity that Xu Panan and Huang Xu both have no memory of the previous night, and all his worries are just his guesses, so he can only ask Xu Panan's parents to check the surveillance video of the previous night with him, and then he specially asked someone to hack the computer of the Nanhu District Street Office, and erase all the images of Xu Panan and Huang Xu left in the surveillance video.

As for the monitoring around the middle school attached to H Normal University, he only needs to inform the person who manages the monitoring, and it can be easily handled.

That is, after this interrogation, the facts are just as Shen Yu thought at the beginning, the information that Yan Kuan can provide them basically has little to do with the 5.20 case.

The only thing that made Long Ya feel relieved was that Yan Kuan also backed up a real video when he asked people to modify the original video, although the video could provide them with limited information, but it was also able to accurately grasp the state of Huang Xu and Xu Panan when they left school and returned home on May 19.

After completing the interrogation of Yan Kuan and transferring back the original video he had modified, the members of the 5.20 case team decided to temporarily put the prosecution of Yan Kuan at a later date after discussion, and now it is not known whether Huang Xu and Xu Panan's homes have been targeted, and at this time, this matter should not be affected too much for the time being, so as not to cause secondary harm to the families of the two high school students.

After getting the original video, Shen Yan and Long Ya were the first to watch it.

Although the video was taken away by Yan Kuan at the beginning, it saved them a lot of investigative effort. In the ten minutes of video time, the figures of the two high school students were completely recorded.

First, a video of leaving the school.

This video is completely consistent with Yan Kuan's original situation with them.

It should have been shortly after dark, and the first night of self-study at school had just begun, when Huang Xu and Xu Panan climbed out of the campus from a wooded courtyard wall on the south side of the school.

The camera is supposed to be hidden under the canopy, and both students flip over the camera without noticing the camera's presence.

"Huh! The school is also enough, this look is a tree planted here on purpose, and then a camera is installed here, and one shot is accurate! While Shen Yan and the two of them were watching the video, Liu Tan's lazy voice sounded behind the two.

Shen Yan looked back and saw Liu Tan tilting his head against the door, holding a cup of hot water in his hand, and his eyes were half-open as if he was about to fall asleep.

"As long as the students don't think about going over the wall, then the camera is useless. The school can't be blamed for that. Just like fishing enforcement, if no one has the right mind, fishing enforcement will not succeed. But aren't you in a group with Officer Wang? ”

Shen Qian pointed to the two students who ran away from the camera without a trace, these two students were obviously the people the school deliberately targeted, but I didn't know if the camera was specially installed for the two of them.

"He! Different roads, we are responsible for our own! ”

The video of the two students escaping from the school is only a two-minute footage, and Huang Xu and Xu Panan climb along the wall like monkeys in these two minutes, without the expression and temperament that seem to be preoccupied in the hospital now.

In this video, they didn't find any particularly valuable clues.

When I turned to look at the footage of several cameras in Nanhu District that night, because the footage was directly captured, the picture jumped out of the picture of two high school students directly in the center of the camera's field of view.

That camera should be the camera at the south intersection downstairs of Xu Pan'an's house, and the time of the camera shows 00:00, that is, it should be the second morning!

In the frost-white street lamp, two teenagers in school uniforms are supporting each other to walk towards the location of the camera, and even if they are holding each other, they seem to be staggering, as if they are drunk.

The camera in Nanhu District is not a high-definition camera, and there is a lot of noise in the image because it is night, and Shen Warriors can only roughly judge from the depth of the color blocks in the picture that the backs of the two high school students' school uniforms are indeed stained with a lot of blood.

When the two helped each other to the intersection downstairs of Xu Pan'an's house, Xu Panan let go of Huang Xu and walked home by holding on to the wall. And Huang Xu continued to stagger towards his own house two rows of unit buildings, without Xu Panan's support, he almost fell to the ground when he walked, and I don't know why the two of them became like this.

After Huang Xu disappeared in this surveillance picture, Huang Xu's figure appeared again in the monitoring screen of the next camera, 00:01.

In terms of timing, there is no problem with the interval between his appearance in the two cameras, and his movements are still the same as in the previous picture, and when he finally returns to the downstairs of his house, he slowly moves back to the unit where he is located.

"Wait a minute!"

Just when Long Ya was about to turn it off after watching all the surveillance videos, Liu Tan, who had been napping in the back, suddenly rushed up and directly pressed Long Ya's hand.

Her eyes widened at the boss, staring at the computer screen and said, "Look! What is it!? ”

When Liu Tan pointed his finger to the corner of the last surveillance screen, in the darkness without lights, a humanoid silhouette nearly two meters tall was slowly disappearing from the flower bed downstairs of Huang Xu's house!
