Chapter 220 Case Analysis Meeting
Looking at the items on the snow, Liu Biao's face was horrified!
Group leader Chen... this, this, this...
Both Liu Biao and Yu Tao knew that what Chen Yan discovered now also belonged to the deceased.
Then, the cruelty of the murderer is very terrifying.
Liu Biao and others originally thought that the things found in the plastic bag were 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 Vocational and Technical College.
Including playgrounds, classrooms, dormitories, everything.
Find all suspected items!
Yes!
Liu Biao should be saluting.
【Ding! The task of the strongest police training system is released. 】
[Finding the playground murder case has a deadline of five days. Complete the task and reward autopsy 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 shine.
Autopsy is a job that requires not only a theoretical reserve, but also the accumulation of on-site experience.
The corpse, though unable to speak.
However, through the characteristics of the corpse after death, many important clues and information can be judged.
For example, the age of the deceased, the cause of death, the extraction of DNA information, etc.
Chen Yan used to investigate the scene more, looking for clues of the suspect left at the scene, and 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 moved very quickly.
Less than an hour after Chen Yan assigned the work,
A large number of detectives and security personnel appeared in the academy with more than a dozen police dogs.
Search jobs, start now.
Starting at 3:30 in the afternoon, the search continued for more than ten hours.
It was not until the next day, at 8 o'clock in the morning on the 19th, that the entire search team finally came to an end.
Anbei City Police Department.
Autopsy room.
All the suspicious items found in this search were placed on the autopsy table.
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 his face was extremely pale.
There are a lot of them.
...
Yu Tao stepped forward, frowning, and pointed to the bones on the table: These...were found in the kennel of the academy.
When they were discovered, some of them had been severely damaged by dogs.
Currently... only some large bones such as the thigh bone, calf bone, and pelvis remain.
and this…………
It was found in the northeast corner of the campus, in the tree hole of an ancient tree.
After the same treatment, the facial features were severely damaged, and it was basically impossible to recognize the appearance before death...
...
meeting room.
The first case analysis meeting.
Chen Yan cut to the chase: This is a very bad murder case.
Moreover, the place where the case happened is in a crowded area.
The impact is very bad, and the Provincial Criminal Investigation Brigade limits us to solve the case within a week!
Chen Yan looked at Zhao Bing on the side, signaling to play the projection.
After preliminary confirmation of the deceased's pelvis, the deceased was female.
Compared to 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 pelvis that has been scarred, and the other is a photo of the head.
First, confirm the identity of the deceased as soon as possible.
Chen Yan looked at Lan Feng: Captain Lan, you are in charge of 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.
Second, conduct an investigation on vocational and technical colleges and surrounding restaurants, slaughterhouses, cold drink shops, and all business places with large freezers.
Projected photo switching.
It was the contents of a 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 relatively regular in size.
Let's see again.
The photo is enlarged.
These items are darker in color, have obvious blood precipitation, and are uniform in thickness.
In this case, the next step is usually after freezing.
Moreover, the murderer did other treatments afterwards.
In this way, the blood will be sealed in the processed items, and the current situation will appear.
Let's take a look at this photo again.
On the projection is a section of thighbone.
The middle part of the bone has traces of cutting with a saw, and the femoral heads on both sides have neatly cut surfaces, and there are no traces of chopping at the joints.
So, it can be concluded from these details.
First, at the scene of the crime, there should be a large freezer that can freeze large objects as a whole.
Second, the murderer should be engaged in butchering, cooking and other similar industries.
When the other party cut the joints, they cut them with one knife. The incisions were smooth and there were no hard chopping marks.
This is 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 in charge of checking all the surveillance cameras in the Technical College.
Especially last night, all those who appeared in the school and carried black plastic bags should be investigated first.
After the deployment was completed, Chen Yan looked at Liu Biao: Captain Liu, the corresponding work still needs 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 here to cooperate with the work of each team member.
The first case analysis meeting is over.
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 possible time!
It was Qin Chuan who personally called.
In this case, the impact is very bad.
After all, it happened in a crowded area.
When the discoverer reported the crime, many people saw the black plastic bag.
The news of a vicious murder in Anbei City has spread.
At this time, the pressure at all levels is very high.
That's why Qin Chuan personally called to inquire about the situation.
After putting down the phone, Chen Yan also felt a lot of pressure.
If nothing else, just talk about Anbei Vocational and Technical College.
Now, the entire academy is in a panic. Although the ban has been lifted, the students are afraid to go downstairs.
The location where the murderer processed the debris in the later stage basically covered the entire academy.
Last night, when hundreds of detectives and security personnel outside were searching, these students also stayed up all night.
The lights in the dormitory were all on, and everyone was on the balcony watching the people below search.
Originally, according to regulations, after 11 o'clock, the lights in the school dormitory will be turned off.
However, just after the lights were turned off yesterday, loud cries came from the female dormitory building.
Shouting and shouting, the dormitory did not turn off the lights and electricity in the end.
Now, although it was dawn, the atmosphere of fear had not dissipated.
Especially after the Anbei City Criminal Police 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 announcement also confirmed the conjectures in the students' hearts.
There was indeed a homicide.
Leaving the lounge, Chen Yan went straight to the autopsy room.
He was to be directly involved in the autopsy process.
For now, in the absence of any clues, the items that have been found are themselves the biggest clues.
