Chapter 221 Case Analysis Meeting

Looking at the items on the snow, Liu Biao looked horrified!

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

Liu Biao and Yu Tao both understood that if Chen Yan discovered something now, it also belonged to the deceased.

Then, the murderer's cruelty is very terrifying.

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

However, the item Chen Yan discovered...

Chen Yan also frowned as he stared at the brown object on the snow.

"Mobilize all police dogs in Anbei City, request support from 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.

【Ding! The strongest police training system mission is released. 】

[Detect the playground murder case. The deadline is five days. Complete the task and you will be rewarded with post-mortem skill specialization. If you fail or exceed the deadline, the task reward will be cancelled. 】

Autopsy skills?

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

Autopsy is a job that requires not only theoretical reserves but also on-site experience accumulation.

The corpse, although unable to speak.

However, many important clues and information can be determined from the characteristics of the body after death.

For example, the age of the deceased, cause of death, DNA information extraction, etc.

When Chen Yan inspected the scene before, he was more looking for clues left by the suspect at the scene. He had basically no contact with the autopsy.

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

Liu Biao moved very quickly.

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

Search work begins immediately.

The search lasted for more than ten hours starting at 3:30 p.m.

It wasn't until 8 a.m. the next day, the 19th, that the entire search team finally ended.

Anbei City Detective Team.

Autopsy room.

On the autopsy table, all the suspicious items found in this search were placed.

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

"The quantity is relatively large."

…

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

"When they were discovered, some of them had been severely damaged by dogs."

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

"and this…………"

"It was found in the cave of an ancient tree in the northeast corner of the campus."

"After the same treatment, the facial features were severely damaged, and it was basically impossible to recognize the appearance in life..."

…

meeting room.

The first case analysis meeting.

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

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

"The impact was so bad that the Provincial Detective Brigade gave us a week to solve the case!"

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

"After preliminary confirmation of the deceased's pelvis, the deceased was female."

"Comparing the degree of wear of the molars, the age is about 20 years old."

On the projection, there are two photos.

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

"First, the identity of the deceased must be confirmed 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.

"Second, conduct an investigation on the vocational and technical college and surrounding restaurants, slaughterhouses, cold drink shops and other business places with large freezers."

Projected photo switch.

Items in a black plastic bag, along with other smaller items found.

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

"These items that have been discovered are all relatively regular in size."

"Everyone, let's see."

Photo enlarged.

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

"In this case, it is usually frozen and then processed in the next step."

"Moreover, the murderer then carried out other treatments."

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

"Everyone look at this photo again."

The projection shows a thigh bone.

"There are traces of saw cutting in the middle part of the bone. The femoral heads on both sides are neatly cut, and there are no signs of chopping at the joints."

"So, you can tell from these details."

"First, there should be a large freezer at the crime scene that can freeze large items in their entirety."

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

"When the other party cut the joints, they cut them off with one knife. The cuts were smooth and there were no hard chopping marks."

"This is something most people can't do."

Chen Yan looked at Zhang Chaoyang: "Chaoyang, you will be 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 those who appeared in the school with black plastic bags in their hands should be investigated in detail."

After the arrangements were completed, Chen Yan looked at Liu Biao: "Captain Liu, the corresponding work still requires your cooperation."

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

"These investigations mainly rely on your strength."

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

The first case analysis meeting ended.

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

"Captain Qin, don't worry, I will do my best to solve the case in the shortest time!"

It was a call from Qin Chuan himself.

This case has a very bad impact.

After all, it happened in a crowded area.

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

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

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

So, Qin Chuan called in person to inquire about the situation.

After hanging up the phone, Chen Yan also felt a huge pressure.

Let's talk about Anbei Vocational and Technical College.

Now, the whole college is panicking. Although the ban has been lifted, students are afraid to go downstairs now.

The places where the murderer dealt with the fragments later basically covered the entire college.

Last night, when hundreds of detectives and security personnel outside were searching, these students did not sleep all night.

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

Originally, according to regulations, the lights in the school dormitory should be turned off after 11 o'clock.

However, just after the lights were turned off yesterday, there was a loud cry from the girls' dormitory building.

After shouting, the dormitory did not turn off the lights and power 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 had occurred, there were no details such as the development of the case.

However, this report also confirmed the students' guesses.

A murder had indeed occurred.

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

He wanted to directly participate in the autopsy process.

At present, in the absence of any clues, the items that have been found are the biggest clues.
