Chapter 220： case analysis meeting

Looking at the items on the snow, Liu Biao's face was horrified!

"Team Leader Chen... this, this..."

Both Liu Biao and Yu Tao understood that if what Chen Yan found now, it also belonged to the deceased.

Then, the cruelty of the murderer is very terrifying.

Liu Biao and others originally thought that what was found in the plastic bag was the smallest unit for the murderer to eliminate the traces of the crime.

However, the item that Chen Yan found...

Staring at the brown object on the snow, Chen Yan also frowned.

"mobilize all the police dogs in Anbei City, request the support of other security forces, and thoroughly search every corner of Anbei City Vocational and Technical College."

"Including playgrounds, classrooms, dormitories, everything."

"Find all suspected items!"

"Yes!"

Liu Biao's salute should be yes.

【Ding! The task of the strongest police training system is released. 】

[Detection of playground murders, within a five-day period, complete the task, reward autopsy skill specialization, fail or cancel the task reward after the deadline. 】

Post-mortem skills?

The system prompt in his mind made Chen Yan's eyes shine.

An autopsy is a job that requires both theoretical reserves and field experience accumulation.

The corpse, though unable to speak.

However, many important clues and information can be judged through the characteristics of the corpse after death.

Such as the age of the deceased, the cause of death, extracting DNA information, etc.

Chen Yan used to investigate the scene, mostly looking for clues that the suspect stayed at the scene, but basically had no contact with the autopsy.

This requires a lot of professional tools and tests, which cannot be seen with the naked eye.

Liu Biao's movements were very fast.

Less than an hour after Chen Yan set up the work, a large number of detectives and security personnel appeared in the academy with more than a dozen police dogs.

Search work, start now.

The search continued for more than ten hours starting at 3:30 in the afternoon.

It was not until the next day, at 8 am on the 19th, that the entire search team finally ended.

Anbei City Detective Team.

Corpse Examination Room.

On the autopsy table are all the suspicious items found in this search.

"In addition to the...things found in the black plastic bag," Liu Biao, who hadn't slept all night, not only had dark circles under his eyes, but also looked extremely pale.

"There are more."

...

Yu Tao stepped forward, frowned, and pointed to the bones on the table: "These... were found in the kennel of the college."

"At the time of discovery, some had been severely damaged by dogs."

"At present... only the thigh bones, calf bones, pelvis bones and other large bones remain."

"and this…………"

"It was found in the northeast corner of the campus, in a tree hole of an ancient tree."

"After the same treatment, the facial features were severely damaged, and it was basically impossible to identify the appearance before death..."

...

meeting room.

The first case analysis meeting.

Chen Yan said straight to the point: "This is a very bad murder case."

"Moreover, the place where the case occurred was in a gathering area."

"The impact is very bad. The Provincial Detective Brigade limited us to solve the case within a week!"

Chen Yan looked at Zhao Bing on the side and motioned to play the projection.

"After preliminary confirmation of the pelvis of the deceased, the deceased was a woman."

"Comparing the wear level of the molars, the age was around 20 years old."

On the projection, there are two photos.

One is a photo of the already scarred pelvis, and the other is a photo of the head.

"First, to confirm the identity of the deceased as soon as possible."

Chen Yan looked at Lan Feng: "Captain Lan, you are responsible for this matter."

Lan Feng nodded. As a member of the serious crime team, Chen Yan directly deployed the work, and Liu Biao and others cooperated well.

"Secondly, conduct investigations on vocational and technical colleges and surrounding restaurants, slaughterhouses, cold drink shops, and other business places with large freezers."

Projection photo toggle.

It was the item in the black plastic bag, along with other smaller items found.

"Although the body was severely damaged, the murderer still left some clues."

"These discovered objects are of relatively regular size."

"Let's see everyone."

The photo is enlarged.

"These items are dark in color, have obvious blood deposits, and are uniform in thickness."

"In this case, it is generally after freezing, and then the next step is processed."

"Moreover, the murderer carried out other processing afterwards."

"In this way, the blood will be sealed in the processed items, and the current situation will occur."

"Look at this photo again."

The projection is a thigh bone.

"In the middle part of the bone, there are marks cut by a saw, and the femoral heads on both sides are neatly cut, and there are no signs of chopping at the joints."

"So, from these details, it can be concluded."

"First, there should be a large freezer at the crime scene, which can freeze the entire bulky items."

"Second, the murderer should be in the slaughtering, cooking and other similar industries."

"In the process of cutting the joints, the other side cuts them off with one knife, the incisions are smooth, and there are no strong marks of cutting."

"It's something ordinary people can't do."

Chen Yan looked at Zhang Chaoyang: "Chaoyang, you are responsible for this matter."

Zhang Chaoyang nodded.

Chen Yan then looked at Zhao Bing: "Zhao Bing, you are responsible for checking all the surveillance cameras in the technical college."

"Especially last night, all personnel who appeared in the school and carried black plastic bags should be investigated."

After arranging the deployment, Chen Yan looked at Liu Biao: "Captain Liu, the corresponding work still requires a lot of cooperation from your side."

"The members of the serious crime team are not familiar with the basic situation here."

"These investigations mainly depend on your strength."

Liu Biao nodded: "Team Leader Chen, don't worry, I will arrange the most elite detectives here to cooperate with the work of each team member."

The first case analysis meeting is over.

In the conference room, Chen Yan was talking on the phone.

"Team Qin, don't worry, I will try my best to solve the case in the shortest time possible!"

It was a call from Qin Chuan himself.

The impact of this case is very bad.

After all, it happened in a crowded area.

When the discoverer reported the case, many people saw the black plastic bag.

The news of a vicious homicide in Anbei City has spread.

At this time, the pressure at all levels is very high.

Therefore, Qin Chuan made a phone call to inquire about the situation in person.

Putting down the phone, Chen Yan also felt a lot of pressure.

If nothing else, just say Anbei Vocational and Technical College.

Now, the entire academy is in a panic. Although the ban has been lifted, students are afraid to go downstairs now.

The location where the murderer later processed the fragments basically covered the entire academy.

Last night, when the hundreds of detectives and security guards outside were searching, these students also stayed up all night.

The lights in the bedroom were all on, and everyone was on the balcony watching the people below searching.

Originally, according to the regulations, after 11 o'clock, the school dormitory will turn off the lights.

But just turned off the lights yesterday, and there was a loud cry from the girls' dormitory.

Shouting and shouting, the dormitory did not turn off the lights in the end.

Now, although it is dawn, the atmosphere of fear has not dissipated.

Especially after the Anbei City Detective Team reported the preliminary case.

Although the report only said that a homicide occurred, there were no details such as the development of the case.

However, this report also confirmed the conjectures of the students.

There was indeed a murder.

Leaving the lounge, Chen Yan went straight to the autopsy room.

He is directly involved in the examination process of the corpse.

For now, in the absence of any clues, the items that have been found are themselves the biggest clues.
