Chapter 227： something strange

Yes, on-campus!

This is what Chen Yan is most concerned about.

The autopsy report is out.

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

The cause of death was mechanical asphyxiation.

Bodies have been frozen and then thawed.

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

Wet at the end.

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

Moreover, the soaking time is concentrated on the evening of the 15th to the night of the 17th.

According to the corpse report, the discarding of corpse objects was not intermittent.

Not a batch on the 15th and then a batch on the 16th.

Finally, the 17th threw the last batch.

But 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 of time, entities have been abandoned.

Therefore, the possibility of the murderer committing crimes in the school is actually the greatest.

The entire Anbei Vocational and Technical College has tens of thousands of students.

There are nearly 2,000 faculty members.

In addition to security, cleaning, etc., there are nearly 15,000 people on the entire campus.

So many people, there are 5 large canteens alone.

There are dozens of other small restaurants.

Therefore, the school is where Chen Yan cares most.

And Zhang Chaoyang also put the most elite force, the focus of work in the school.

"Team leader, in the school, we conducted detailed investigations on 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.

5 large canteens, all the recent chefs have done a survey.

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

"After 7 p.m., the canteen is cleaned, and the cooks and waiters leave work."

"It wasn't until 4am the next morning that the doors of the canteen would open and the cooks and waiters would go to work to prepare the day's ingredients."

"Moreover, the keys to the cafeteria are kept in the hands of special personnel, and the surveillance cameras at the door have also been checked."

"During the incident, there were no suspicious signs."

School cafeterias are different from ordinary restaurants.

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

The chef is in charge of cooking, the waiter is in charge of cooking, and the handling of ingredients is handled by special personnel.

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

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

After the projection was switched, Zhang Chaoyang continued to report: "We also investigated the 36 privately contracted restaurants on campus."

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

"No problems were found!"

Are there any problems?

That is to say, Chen Yan's inference about the identity of the murderer based on some characteristic clues of the corpse's swindle is basically wrong.

Because, everyone in this direction is basically not suspicious.

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

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

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

During the period from the 15th to the 17th, the murderer continuously abandoned Ruan Xiaoqing's body and cheated, and it is very likely that it will be captured by the video camera.

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

"Among them, most of them are installed in teaching buildings."

"A total of 132."

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

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

However, the effect is very unsatisfactory.

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

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

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

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

Anbei Vocational and Technical College has been running for a long time and the teaching quality is very good.

In the whole Liao Province, it is actually quite famous.

It has also cultivated many skilled talents.

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

"The college has been transforming 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 the outdoor monitoring equipment, in addition to the high-definition monitoring of the newly built parking lot, the monitoring in other places is either broken."

"Either it's a very old model that doesn't shoot clearly."

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

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

"All, it is very difficult to investigate."

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

"Moreover, the inspection of pedestrians at the gate of the school is not too strict."

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

"Form outweighs meaning."

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

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

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

Zhao Bing brought back very few clues.

The fence of Anbei Vocational and Technical College is also not in place with protective measures.

There is no electronic fence installed.

Many students skip class by flipping through the fence and running.

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

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

The way to find wet suspects through video will not work.

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

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

The second case analysis meeting is over.

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 the two major suspects who now have directions.

Both of them have the skill reserve of killing each other, one is a cook, and the other has done slaughter.

Moreover, Feng Ruihao's murder motive is very obvious But the point is, even if the two are murderers, why should they abandon the corpse to the school after the loss of the year?

Aging is easy to understand.

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

Basically, the characteristics of human flesh tissue have been lost.

This kind of small debris is difficult to find wherever it is thrown.

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

Hide the head in the hollow of the tree and throw the bones into the kennel.

Wet, there has always been a saying.

Buried far and near.

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

No one has ever been soaked in the doorway after killing someone in their own home.

They all choose to be buried.

Soak wet, usually go to a relatively familiar, and some far away place.

For example, the case of dumping corpses in a pond in the suburbs of Shenshi is the case.

However, the murderer of Ruan Xiaoqing violated these basic rules.

Murderers who kill, don't seem to care about just letting people die.

Soaking seems to be the fundamental purpose.

However, either Feng Ruihao or Qin Jiangkai.

If one of these two really was the murderer, why did they do it?

20th at 4:30pm.

Tomorrow is the winter solstice, and now is the shortest time of year for sunshine.

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

Lan Feng, who was in charge of investigating the surveillance video of Qin Jiangkai Community and investigating the specific whereabouts of Ruan Xiaoqing after leaving Qin Jiangkai Community on the morning of the 11th, came back.

"Team leader, things are a little strange!"
