Chapter 228 Things Are a Bit Strange

Yes, on campus!

This is what Chen Yan is most concerned about.

The autopsy report has come out.

The specific time of Ruan Xiaoqing's death was probably between the 11th and the 12th.

The cause of death was mechanical asphyxiation.

The body had been frozen and then thawed.

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

Finally soaked.

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

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

According to the autopsy report, the abandonment of body objects was not intermittent.

It was not that a batch was thrown on the 15th, and then a batch was thrown on the 16th.

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

Instead, 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.

During this continuous period, entities were abandoned.

Therefore, the possibility that the murderer committed the crime on campus is actually the greatest.

The entire Anbei Vocational and Technical College has more than 10,000 students.

There are nearly 2,000 faculty and staff.

In addition to security guards, cleaners, etc., the entire campus has nearly 15,000 people.

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

There are dozens of other small restaurants.

Therefore, the campus is the place that Chen Yan is most concerned about.

And Zhang Chaoyang also puts the most elite forces and focuses on the school.

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

The investigation inside the vocational and technical college is much more detailed than the investigation outside the school.

A survey was conducted on the recent situation of all chefs in the 5 large canteens.

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

"After 7 o'clock in the evening, the canteen is cleaned and the chefs and waiters go off work."

"The canteen door will not be opened until 4 o'clock the next morning, and the chefs and waiters will start work to prepare the ingredients for the day."

"In addition, the keys to the canteen are kept by 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 restaurants.

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

The chef is responsible for cooking, the waiter is responsible for serving meals, and the processing of ingredients is the responsibility of a dedicated person.

"The same is true for the canteen's cold storage, which is managed by a dedicated person and is responsible for the entry and exit of ingredients and counting."

"Basically, there is no possibility of committing a crime."

The projection switches, and Zhang Chaoyang continues to report: "We have also investigated the 36 individual contracted restaurants on campus."

"Boss, chef, waiter, refrigerator..."

"No problems were found!"

No problems?

In other words, Chen Yan's inference about the murderer's identity based on some characteristic clues of the corpse was basically wrong.

Because basically no one in this direction was suspected.

The clues that Zhang Chaoyang was responsible for were basically interrupted.

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

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

The murderer continuously abandoned Ruan Xiaoqing's corpse from the 15th to the 17th, and it is very likely that he was captured by the video camera.

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

"Among them, the vast majority are installed in the teaching building."

"A total of 132."

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

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

However, the effect was very unsatisfactory.

"Anbei Vocational and Technical College has a large number of students, the school campus is not large, and the monitoring equipment is also seriously aging."

"There are very few valuable clues that can be obtained."

In fact, strictly speaking, it is not very few, but basically none.

It does not mean that there is a problem with Anbei Vocational and Technical College.

Anbei Vocational and Technical College has been in operation for a long time and has very good teaching quality.

In fact, it is quite famous in the whole Liaoning Province.

It has also cultivated many skilled talents.

However, it is precisely because the school itself is relatively good that the monitoring equipment was installed relatively early.

"The college has been gradually upgrading the surveillance equipment on campus in the past two years."

"However, so far, only the surveillance equipment in the teaching building has been upgraded."

"As for the outdoor surveillance equipment, except for the high-definition surveillance in the newly built parking lot, the surveillance in other places is either broken."

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

"In addition, there are many teachers and students in the school."

"There is also a family area in the school, and there are many people exercising in the evening and in the morning."

"Therefore, it is very difficult to check."

According to Zhao Bing's investigation results, Anbei Vocational and Technical College has a small campus area and a large flow of people. Whether it is day or night, there are people on campus.

"In addition, the screening of pedestrians at the school gate is not very strict."

"As long as they are looking for someone, or live here, they will be allowed in."

"The form is more important than the actual meaning."

"However, the school gate has very strict management of motor vehicles. Only the cars of school teachers or the cars of family members living in the school can enter after filing."

"Therefore, we believe that the possibility that the murderer drove into the school from a distance and soaked can be basically ruled out."

"The murderer must live in the surrounding area, or it is very likely that he is in the school."

Zhao Bing brought back very few clues.

The walls of Anbei Vocational and Technical College are not well protected.

There is no electronic fence installed.

Many students skip classes by climbing over the fence.

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

Students can climb over the fence, and of course others can climb over the fence.

The method of finding the suspect who soaked through the video is not feasible.

From the current point of view, the relevant clues have been basically checked.

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

The second case analysis meeting ended.

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

Feng Ruihao and Qin Jiangkai are the two major suspects with a direction now.

Both of them have the skills to kill people, one is a chef and the other has done butchering.

And Feng Ruihao's motive for killing is very obvious.

But the key is, even if they are the murderers, why did they abandon the body in the school after the death?

The death is easy to understand.

Ruan Xiaoqing's body was cut into pieces and then treated with boiling water.

Basically, it has lost the characteristics of human flesh and blood.

Such small fragments are difficult to be found wherever they are thrown.

However, the other party not only soaked all the bodies on the campus, but also deliberately left a broken finger on the 17th.

Hide the head in a tree hole and throw the bones into the dog kennel.

Soaking, there has always been a saying.

Throw far and bury near.

This is a psychological suggestion, a self-psychological suggestion of the murderer to destroy the body.

No one has ever soaked the body at his door after killing someone at home.

They all choose to bury it.

Soaking, generally go to a relatively familiar and somewhat far place.

For example, the case of dumping corpses in the pond in the suburbs of Shen City is like this.

However, the murderer who killed Ruan Xiaoqing violated these basic rules.

The murderer did not seem to care about just killing people.

Soaking seems to be the fundamental purpose.

However, whether it is Feng Ruihao or Qin Jiangkai.

If one of these two people is really the murderer, why did they do this?

4:30 pm on the 20th.

Tomorrow is the winter solstice, and now is the time with the shortest sunshine in the year.

At 4:30 in Anbei City, the sky is already dark, and the sun is about to set.

Lan Feng, who is responsible for investigating the surveillance video of Qin Jiangkai Community and investigating Ruan Xiaoqing's specific whereabouts after leaving Qin Jiangkai Community on the morning of the 11th, is back.

"Team leader, things are a bit strange!"
