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

Chapter 679 An Unexpected Discovery on Campus

The footprints on the windowsill of the teaching building have been collected. If necessary, Qin Chuan will organize relevant personnel to collect footprints from all the people in the school and then compare them one by one.

Before that, Qin Chuan, Zhang Qiang and others went to the canteen where Gao Yunfeng had eaten before he disappeared.

The entire Linzhou University covers an area of ​​more than 100 acres, with a total of more than 2 teachers and students. There are five canteens on campus alone.

The cafeteria where Gao Yunfeng ate that day was the closest to the teaching building where they had classes, and it was also not far from their dormitory.

According to Gao Yunfeng's roommates, they did not notice anything unusual about him that day. The night before the incident, Gao Yunfeng played games with his roommates until late at night, so he was in poor spirits on the morning of the incident. Several of his roommates slept and did not attend classes.

Zhang Qiang has arranged for criminal police to conduct a detailed investigation into all the circumstances and details of Gao Yunfeng's life on the day before he was killed, but they found nothing suspicious. In other words, Gao Yunfeng knew nothing before he was killed.

"However, we checked Gao Yunfeng's call records. He did not receive any calls when he left with his roommates after lunch that day. In other words, Gao Yunfeng could not have separated from his roommates for no reason. He must have gone to see someone."

But who exactly is this person? The police have been unable to find out.

Qin Chuan sat at the table next to where Gao Yunfeng had eaten, carefully observing his surroundings.

This cafeteria occupies a considerable area, with three floors. The first floor can accommodate approximately four to five hundred people for dining.

There is CCTV footage at the restaurant entrance, and the police have investigated the relevant information from the footage. After finishing his meal, Gao Yunfeng turned right and left his roommates, while his other roommates turned left and returned to their dormitories.

“Let’s go, let’s follow the path Gao Yunfeng took and take a walk around it.”

According to the surveillance footage, Gao Yunfeng disappeared on Qiuzhi Road.

Surveillance cameras on Qiuzhi Road have captured Gao Yunfeng's image, but there are several side roads next to him, one of which leads to the teaching building where the incident occurred.

At this moment, Qin Chuan was standing on his job search road, at the fork in the road leading to the teaching building where the incident occurred.

It's lunchtime right now, and there are a lot of students crossing the intersection. Because the intersection is close to the teaching building, many people take a shortcut and cross the lawn, which has gradually formed a path.

This road passes through a small grove of trees, which is about 700 or 800 meters away. After you come out of the grove, there is another road next to the school building where the crime scene was located.

Qin Chuan walked along this road.

The streets were filled with students rushing to class.

It's almost noon now.

Some students had already left school in the morning, while others were on their way to the cafeteria. In other words, there were quite a few people coming and going on this road. Qin Chuan thought it was unlikely that Gao Yunfeng would have gone missing on this road.

Suddenly, Qin Chuan stopped in his tracks.

He glanced at a building on his right.

"What is this place?"

Zhang Qiang looked at it and said, "Oh, this is an experimental building at Linzhou University. Chemistry students are doing experiments inside."

Chemical?

Laboratory building?

"Let's go over and have a look."

Today, Qin Chuan, along with Zhang Qiang and several other criminal police officers, crossed this tree-lined path and arrived directly in front of the chemistry laboratory building. After standing there for a short while, Qin Chuan went inside and walked to the left.

The building isn't very big; there are several classrooms on both the left and right sides when you walk past it to the left.

Qin Chuan stood at the door of one of the classrooms.

"Tobacco-related major?"

Zhang Qiang nodded: "Tobacco science is a prestigious major at Linzhou University. Graduates usually have good career prospects. This lab should be a lab for blending tobacco shreds and such."

"Director Qin, should I call the relevant person in charge over?"
