Chapter 222 Dragon Sky Tattoo (Please Vote and Subscribe)

Four detectives and five assistants were responsible for the autopsy.

This is the Anbei City Detective Team, all the forces responsible for autopsy work.

The Anbei City Detective Team is relatively small in the Liao Provincial Detective Brigade system.

There are only two subordinate detective squads.

"Team Leader Chen, why are you here?"

The team leader responsible for the autopsy is a veteran detective and the master of all the detectives responsible for the autopsy at the scene.

Within the Chinese detective system, the police academy has a major that specializes in training autopsy detectives.

It’s just that the number of students is relatively small, usually one class per session.

However, what you learn in the police academy involves more theoretical knowledge and less practical experience.

Real learning begins when you are assigned to various grassroots detective teams.

In this industry, the most important thing is mentoring and mentoring.

Each of the older generation of autopsy detectives is a valuable asset.

If nothing else, this industry requires a lot of experience.

And if you work long hours, you will naturally gain more knowledge.

"I came over to take a look at the progress of the work here."

The veteran detective in charge is Fei Shoucheng, 56 years old, who retired within a few years.

"Captain Fei, how is the work going here?"

"Team Leader Chen, you're welcome, just call me Lao Fei."

Fei Shoucheng smiled and welcomed Chen Yan to the autopsy table.

"We are working on body recovery first."

"Progress has been very slow."

Lao Fei pointed to the objects that had filled the entire examination room: "The murderer's modus operandi is very detailed."

"The items found at the scene have been treated with high temperatures and will shrink."

"It's hard to tell where these things belong."

"Therefore, it is basically impossible to completely restore the victim's original appearance."

"But..." Lao Fei paused and walked to the side of the examination room with his statement, where a young man was squatting on the ground: "We also made a discovery."

"Look..."

Chen Yan came forward and squatted on the ground, watching the young man playing with some items with similar patterns.

"The victim seems to have a tattoo on his back. We are trying to find items with similar traces of the pattern and try to restore the pattern."

The assistant squatting on the ground is like playing a jigsaw puzzle, finding the part with the picture among the things in the room.

Tattoo?

The visual gene lock was opened, and the found pattern appeared in Chen Yan's mind.

A tattoo indeed.

Chen Yan had just received a tattoo cognitive map as a reward for the previous case, and now he is particularly handy in analyzing it.

The pattern that appeared in Chen Yan's mind was a blue-themed decoration.

However, after high-temperature treatment, the color becomes lighter and somewhat blurry.

Moreover, due to the phenomenon of compaction, the line pattern is somewhat deformed.

Following the texture, what appeared in Chen Yan's mind was part of a pattern that resembled a peacock feather.

"Old Fei, get me a pair of gloves."

…

Gently twisting one of the objects, Chen Yan observed it carefully.

Although it has been cooked in boiling water and has undergone severe shrinkage, because of this, the pores are enlarged and the surface is tightened. The color of the pattern on it is somewhat faded, but some marks are more obvious.

Modern tattoos use a tattoo gun to make small holes in the skin, and then inject different pigments into the skin while making the holes.

Thus achieving color adhesion.

From the color of the tattoo and the depth of the holes, you can determine the approximate age of the tattoo.

These tattoos of the deceased...

There is some brown residue inside the hole, and there are obvious bulges around it.

There should be signs of redness and swelling before treatment.

In other words, the tattoo time of the deceased was relatively short.

Because it must have been decorated recently.

"Any other discoveries?"

Lao Fei nodded: "There is more."

"Team Leader Chen, look at these objects."

On the inspection table, dozens of objects of different sizes are placed.

"These organizational objects have different levels of corruption."

"Although these objects were treated with high temperatures, because the weather is cold now, the murderer did not decompose quickly after discarding them."

"But it was preserved at low temperatures."

"However, even at low temperatures, objects still have a certain degree of corruption."

"But, look," Lao Fei picked up an object and handed it to Chen Yan. The smell of corruption hit his nostrils: "There are different degrees of corruption."

"We analyzed it and found about three objects with different levels of corruption."

"Based on the comparison with the degree of spoilage of the contents of the plastic bags found today."

"It can be preliminarily determined that the abandonment time of these objects should be from the 15th to the 16th and 17th, for three consecutive days."

Chen Yan observed carefully and indeed discovered the differences between these objects.

There are subtle differences just in color.

"Are you saying that the murderer first acted four days ago and then abandoned each other within two days?"

Lao Fei nodded: "It can't be wrong. I have tested it twice, and there is basically nothing wrong."

Standing up, Chen Yan frowned slightly.

Today is the 19th.

The murderer started discarding these objects four days ago on the 15th.

In other words, the deceased was killed at least before the 15th.

"Where is the head? Have you found anything on the head?"

Lao Fei shook his head: "Judging from the degree of corruption in the head, the murderer should have been abandoned on the 15th."

"We've checked and there's nothing special."

"The deceased's ears were pierced, but no earrings were found."

"Also, it's this finger in the black plastic bag."

"The ring above is very new and fits the deceased's finger very well. It should be her own ring."

"But, you see..."

The severed finger was placed on a workbench, and the ring had been removed: "There are no ring marks on the finger from wearing the ring for a long time."

Chen Yan nodded.

Lao Fei is right.

Wearing a ring for a long time will cause the skin color of the finger to differ from light to dark, forming a circle of lighter marks.

However, this is the same color as the little finger, the top and bottom are the same, and there are no circle marks.

In other words, the deceased had not worn the ring for a long time.

…

Three hours later, Chen Yan left the autopsy room.

Although the body was rendered unrecognizable by the murderer, there are still many clues.

The most difficult crime to solve is killing without a plan or reason.

Killed with one knife and disappeared from the distance.

As long as there are no witnesses and no video surveillance assistance, this kind of case is the most difficult to solve.

On the contrary, it is a murder case with such complicated methods, because the murderer has to make more preparations to deal with the body of the deceased.

Relatively speaking, it is easier to solve the case.

Such as this case.

Although there are still no clues about the murderer, there are freezers, saws, and good knife skills...

These can probably delineate the murderer's professional characteristics.

Even if the murderer is not within this scope, he should have been engaged in related work.

At present, in addition to the clues that Chen Yan has arranged for Lan Feng and others to investigate, a lot of new information has been provided to Chen Yan during the autopsy.

First, it’s time to dump the body.

Based on the degree of corruption of the objects that have been found, it can be inferred that it was on the night of the 15th to the 17th.

What does this mean?

First, it is possible to determine the starting time when the victim was killed, before the 15th.

Second, he can determine the identity of the murderer and can enter and leave the school at will.

this point is very important.

Anbei Vocational and Technical College, although outsiders are not prohibited from entering the school.

However, if the murderer is someone outside the school, there will definitely be clues left when he enters and exits the campus for three consecutive days from the 15th to the 17th.

If the murderer is someone from the school, then the scope of the investigation can be further narrowed.

Chen Yan called Zhao Bing and reminded Zhao Bing to pay special attention to these details when checking the video information.

Also, there are the tattoos on the corpse.

The tattoo on the deceased's body was relatively large. From Chen Yan's analysis, it was initially confirmed that it was a large tattoo covering the back.

Moreover, the tattooing time of the deceased should be relatively short, no more than one month at most.

Such a large tattoo cannot be completed in one go.

It needs to be completed in sections, and it may take several times of coloring to achieve the desired effect.

Anbei City is not big and there are not many tattoo shops.

There should be fewer people who can do such large tattoos.

In the conference room, Chen Yan looked at Wang Gang: "Wang Gang, you are responsible for investigating the origin of the tattoo on the deceased's back. You must find the tattoo shop that tattooed the deceased in the shortest possible time."

Wang Gang nodded, took the tattoo information handed over by Chen Yan, and led a group of detectives from the Anbei City Detective Team to start investigating the tattoo situation.

Chen Yan handed over the last task to Liu Qingshan.

That was the ring on the dead man's hand.

"Judging from the wear and tear on the ring, the deceased had not worn it for a long time."

"The material is platinum. Investigate all jewelry stores in Anbei City to find out who bought this ring and why it appeared in the hand of the deceased."

This ring was probably left intentionally by the murderer.

Because it is not difficult at all to take off this ring.

Instead, it is possible for the police to use the ring to identify the deceased.

From the perspective of concealing the identity of the deceased, the benefits of removing the ring are relatively large.

However, the murderer did not do this.

What does this mean?

It shows that the murderer is not looking for money first.

A platinum ring costs several thousand dollars at least.

Second, it shows that the murderer does not seem to care much about the identity of the deceased being exposed.

Even, to a certain extent, the murderer deliberately exposed the deceased.

Why?

Very simple.

The case was discovered because there was a severed finger in a black plastic bag.

It is this truncation that causes students to report crimes.

Without this amputated finger, this murder case might not have been discovered at all.

After all, the killer had disposed of the body to a state that was nearly unrecognizable.

From the beginning of processing on the 15th to the discovery of the severed finger on the 17th, no one discovered these objects at all.

Chen Yan even believed that the main reason why the murderer threw out the black bag with a severed finger inside on the 17th was to have the murder discovered!

All work is carried out in an orderly manner.

6:28 pm on the 19th.

"Boss, the tattoo shop that tattooed the deceased...has been found!"

The first person to report the news was Wang Gang.

Although Wang Gang got his job arrangement late, there were not many tattoo shops in Anbei City.

And the local detectives found two tattooed thugs to investigate, and everything became clear.

A stack of information was placed in front of Chen Yan.

"Longkong Tattoo?"
