Chapter 228 Things are a little strange

Yes, on campus!

This is what Chen Yan pays most attention to.

The autopsy report has been released.

The specific time of Ruan Xiaoqing's death is about the 11th to 12th.

The cause of death is mechanical asphyxiation.

The body was once frozen and then thawed.

During the thawing process, the murderer treated it with boiling water.

Finally soak and wet.

Moreover, from the analysis of the total weight of Ruan Xiaoqing's body that has been discovered, it can now be determined that it was basically abandoned on campus.

Moreover, the time for soaking is concentrated from the night of the 15th to the night of the 17th.

According to the corpse report, the abandonment of corpse objects is not interrupted.

It wasn’t that one batch was thrown on the 15th, and then one batch was thrown on the 16th.

Finally, the last batch was sold on the 17th.

Instead, it starts from the night of the 15th to the day of the 16th, the night of the 16th, the day of the 17th, and the night of the 17th.

In this continuous period, entities are abandoned.

Therefore, the possibility of the murderer committing crimes on campus is actually the greatest.

There are tens of thousands of students in the entire Anbei Vocational and Technical College.

There are nearly two thousand faculty members.

In addition to security, cleaning, etc., the number of people on the entire campus is nearly 15,000.

With so many people, there are 5 large canteens alone.

There are dozens of other small restaurants.

Therefore, the school is what Chen Yan cares most about.

Zhang Chaoyang also focused his most elite force in the school.

"The team leader, in the school, we conducted a detailed investigation of 5 large canteens and 36 small restaurants."

The investigations within the vocational and technical colleges are much more detailed than those outside the school.

The recent situation of all chefs in 5 large canteens has been investigated.

"However, the management of these five canteens is relatively standardized."

"After 7 o'clock in the evening, the canteen was cleaned and the chef and waiter got off work."

"It will not be until 4 a.m. the next morning, when the canteen door will open, the chef and waiter will start working and prepare the ingredients for the day."

"Also, the keys to the canteen are kept in the hands of a dedicated person, and the surveillance cameras at the door have also been checked."

“During the incident, there were no suspicious signs.”

The school canteen is different from ordinary hotels.

The transportation and storage of vegetables, rice, flour, oil, meat, eggs, milk and other ingredients are all processed.

The chef is responsible for cooking, the waiter is responsible for making food, and specialized personnel are responsible for handling the ingredients.

"The same is true for the cold storage in the canteen. It has a dedicated person to manage the in and out of the warehouse and inventory of ingredients."

"There is basically no possibility of committing a crime."

After the projection switch, Zhang Chaoyang continued to report: "We also conducted an investigation on the 36 individual contracted restaurants on campus."

"Boss, chef, waiter, freezer..."

"No problem was found!"

No problem?

In other words, Chen Yan’s inference about the identity of the murderer based on some characteristic clues of the corpse year-old fraud is basically wrong.

Because, basically no one in this direction is suspicious.

The clues Zhang Chaoyang was responsible for were basically interrupted.

"Zhao Bing," Chen Yan looked at Zhao Bing for a moment, "How is the inspection of the video?"

There are many video cameras in Anbei Vocational and Technical College.

The murderer uninterruptedly abandoned Ruan Xiaoqing's body and cheated him for a long time from the 15th to the 17th, and was likely to be captured by the video camera.

"Team leader," Zhao Bing stood up and looked at Chen Yan and everyone: "There are 185 cameras in this school."

"Most of them are installed in the teaching building."

“There are 132 in total.”

"The remaining 53 cameras are distributed on the front and back doors of the campus, the walls, and the backbone roads on the campus."

Zhao Bing began to report on the investigation of the school's surveillance camera.

However, the effect is very unsatisfactory.

"There are many students in Anbei Vocational and Technical College, the campus area is not large, and the monitoring equipment is also quite aging."

“There are very few valuable clues that can be obtained.”

In fact, to be rigorously speaking, it is not very few, but basically none.

It’s not that there is something wrong with Anbei Vocational and Technical College.

Anbei Vocational and Technical College has a long time to run and has very good teaching quality.

In fact, they are quite famous throughout Liao Province.

Many skilled talents have also been cultivated.

However, it is precisely because the school itself is better that it was installed earlier that time.

"The college has been renovating the monitoring equipment on campus in the past two years."

"However, so far, only the monitoring equipment in the teaching building has been upgraded and renovated."

"And the outdoor monitoring equipment, except for the new parking lot with high-definition monitoring, the monitoring in other places is either broken."

"Or it's a very old model and the shooting is not clear."

“And, there are many teachers and students in the school.”

"There is also a family area in the school, and there are also many people who exercise at night and in the morning."

"All, it's very difficult to check."

According to Zhao Bing's survey results, Anbei Vocational and Technical College has a small campus area and large personnel flow. There are people on campus whether it is day or night.

"Also, the inspection of pedestrians at the school gate is not very strict."

"Anyone who is looking for someone or who lives here will let you in."

"Form is greater than actual meaning."

"However, the management of motor vehicles at the school gate is very strict. Only the car of the school teacher or the car living in the family yard of the school can be entered after filing."

"So, we think the possibility of the murderer driving into school from a distance can be basically ruled out."

"The murderer must be living nearby, or is in the school very likely."

Zhao Bing brought back very few clues.

The protective measures of the walls of Anbei Vocational and Technical College are not in place.

No electronic fence is installed.

Many students skip classes and run through the fence.

For example, in order to take a shortcut to the back mountain, Feng Ruihao did not go through the back door, but directly climbed over the fence.

Students can turn over fences, and of course others can turn over fences.

The way to find the suspect wet through video is not working.

From the current perspective, all relevant clues have been basically checked.

However, Chen Yan and others did not find any directive clues.

The second case analysis meeting ends.

In the office, Chen Yan looked at the messy information on the whiteboard, but kept thinking in his mind.

Feng Ruihao and Qin Jiangkai are two major suspects who are now in a direction.

Both of them have the skill reserves of killing people for a long time, one is a chef and the other has done slaughter.
