The crackdown on organized crime began with the arrest of the mother-in-law.

Chapter 677 Qin Chuan's Discovery

Gao Yunfeng parted ways with his roommates between 10:30 and 11:00.

Following his usual routine, Gao Yunfeng would go back to his dormitory to rest after having lunch with his classmates in the morning. Of course, this rest didn't necessarily involve sleeping; they would usually play games on their phones during lunchtime.

That afternoon, Gao Yunfeng was supposed to have a professional class, but he asked his classmate to ask for leave. After lunch, he did not return to his dormitory with his roommates, but left directly.

No one knows where Gao Yunfeng went after leaving for lunch.

“We retrieved the school cafeteria’s surveillance footage and found that after Gao Yunfeng left the cafeteria, he left along the Qiuzhi Road on the right side of the school, but this direction does not lead to the school gate.”

After confirming Gao Yunfeng's identity, Zhang Qiang and his team sent people to check a large amount of surveillance footage at the school and obtained some valuable clues.

The path leading to knowledge leads to the school's gymnasium, playground, and physical training center.

“We then reviewed the surveillance videos from the gymnasium playground and the physical training center, but found that Gao Yunfeng did not go to these three places. After he was on his job search route, the surveillance video showed that he left from a fork in the road.”

The fork in the road is shown above, and it is one of the paths leading to the lecture hall where the crime scene was located. Actually, it is not a road, but many students have walked on it, and the shade of the trees in the woods has been worn into a small path.

"There are surveillance cameras outside the lecture hall where the incident occurred, but we reviewed the video and found no trace of Gao Yunfeng. From the time Gao Yunfeng disappeared yesterday afternoon until this morning, the surveillance video showed the entrance to the lecture hall, but we found nothing."

There is only one main entrance to the lecture hall. The building has four floors, with two lecture halls on each floor.

Qin Chuan had entered this scene. After entering the main gate, there was a staircase on both the left and right sides. Following the stairs to each floor, there was a lecture hall on both the left and right sides. The lecture hall where the crime scene occurred was located on the left side of the first floor of the teaching building, right after entering the main gate.

"So, you found through surveillance footage that Gao Yunfeng disappeared while job hunting yesterday at noon, and there has been no further surveillance footage of him going anywhere?"

"Yes, that fork in the road was also one of our guesses, but there were many students on the road right after lunch yesterday. It's unlikely that Gao Yunfeng was kidnapped or that some other emergency caused him to disappear. During this process, only that fork in the road was not monitored, and that fork in the road leads to the lecture hall where the incident occurred. Gao Yunfeng died in that lecture hall, so we believe there is a necessary connection between them."

Qin Chuan frowned.

Zhang Qiang's deduction is reasonable, but there was a class in the lecture hall where the incident occurred yesterday afternoon.

When Qin Chuan went to the classroom today, he saw the class schedule in the lecture hall. Yesterday afternoon, there was a calculus class in the lecture hall taught by first-year students.

In other words, it is impossible that Gao Yunfeng went directly to the lecture hall where the incident occurred after he disappeared at noon, because there were classes in that classroom in the afternoon.

Moreover, it was a first-year advanced mathematics class. Did Gao Yunfeng actually attend this advanced mathematics class in this lecture hall? That seems unlikely.

Another important clue is that the surveillance footage at the entrance of the lecture hall where the incident occurred did not capture Gao Yunfeng entering the lecture hall. So how did he end up in the lecture hall?

Does anyone have any other opinions or clues?

That's all the clues we have about Gao Yinfeng so far; we haven't found any other relevant leads.

Qin Chuan looked around.

"Okay, then I'll give you the instructions for the next steps."

First, Zhang Qiang, you need to have someone check all the windows on the first floor of the lecture hall for signs of climbing. How did the other person get in? The surveillance footage didn't show the killer. How did the killer get in? How did the killer leave? If they didn't use the main entrance, then besides breaking a window, there's probably no other option. The killer couldn't have just walked through the wall.

"In addition, we conducted a survey among the first-year students who attended classes yesterday afternoon to see if they noticed any unfamiliar people, older students, or anyone in the classroom that Gao Yunfeng was definitely present."

"The third Gao Yunfeng was killed, and his skin was peeled off and shaped into a butterfly. This is obviously not a common murder for money or a murder out of resentment. The murderer must have had an important reason for doing this."

Qin Chuan thought about this for a long time.
