Chapter 275 Fertilizer

Something is wrong?

The others were also a little confused.

Chen Yan had circled around these trees for several times.

There was nothing special about this shrub forest, and there was nothing special about this area.

It was just that the trees that Chen Yan circled around were a little taller.

Other shrubs were no taller than one meter, but these few trees looked a bit out of place.

They were growing well, and their trunks were thick and strong.

Chen Yan shook his head: "Just now, Qiao Shanhe said that these dwarf trees were planted ten years ago."

"Well, he said that no one usually takes care of them, and no one fertilizes them. It is a natural growth state."

"So..." Chen Yan touched the tallest tree among them: "Why are these trees growing obviously better than other trees?"

"Why are they taller than other trees?"

"This...it may be that the fertility of this piece of land is better, so the trees grow better?"

"Yes!" Chen Yan nodded and looked at Wang Gang, then looked at the tree: "You are right, these trees grow so well, it should be that the fertility of this piece of land is better."

"But..."

Chen Yan raised his head and looked at Wang Gang again: "Why is the fertility of this piece of land better than other places?"

"Is it...there is something buried under this ground?"

Buried something?

Wang Gang is not a fool. When Chen Yan said this, Wang Gang naturally knew what Chen Yan meant.

"Captain Chen!"

"You mean, Qiao Shouhe is buried here?"

"That's not certain, but..."

Chen Yan pointed to the ground under the dwarf tree and rubbed away the dead branches on it. "Just dig it up and take a look, won't you know?"

"Okay!"

Chen Yan's reasoning is not unreasonable.

This piece of land is not much different from other places, but the dwarf trees are taller than other places.

Why?

You know, after the corpse rots and decomposes, it is the best fertilizer.

If Qiao Shanhe was really buried here...

Wang Gang immediately arranged detectives to start digging.

However, after half an hour of digging.

"Captain Chen, this piece has been dug one meter deep, and there is nothing to find."

Nothing to find?

Chen Yan approached the edge of the deep pit, frowned and looked inside: "Keep digging."

"Use the tallest tree as the center, dig down first!"

Several detectives in charge of digging continued to swing their pickaxes, concentrating their strength, digging deeper with the best growing tree as the center.

At the scene, Qiao Shanhe, Zhao Dongfeng and others were sent back by Chen Yan after they finished walking along the ridge for the first time.

Currently, all the detectives present were from the second detective team.

The detectives in charge of the excavation were from the trace identification team.

After another quarter of an hour, the depth was almost two meters.

But the crowd still found nothing.

Chen Yan has been standing by the pit, staring closely at the work inside the pit.

If no clues are found here, the investigation of the case will be very passive.

Five years have passed, and there were very few clues in the case that year.

And it was also involved in a traffic accident.

However, the current physical discovery is nothing except a broken arm.

Whether Zhao Dongfeng's confession is true or false, Chen Yan has no way to distinguish the truth from the false.

There is no evidence to prove whether what he said is true or false.

The same is true for Qiao Shanhe's confession.

There were only Qiao Shanhe and Qiao Shouhe in the car that year, and no one knows what happened specifically.

Finding Qiao Shouhe's body is the only work that can be advanced at present.

Maybe the murderer will be...

Bang!

A dull crash interrupted Chen Yan's thoughts.

"Captain Chen, Captain Chen!"

"Got it! Got it!"

Under the deep pit, the detective shouted excitedly.

"What did you find?" Wang Gang also looked excited, leaning on the edge of the deep pit and shouting down.

"It's a sharp knife!"

The crash was the crash between the pickaxe and the metal.

The detective in charge of the excavation found a sharp knife underground!

With the discovery, the pickaxe can no longer be used for digging.

After changing to the special tools for on-site investigation, the detective below began to dig carefully.

However, half an hour had passed, but no discovery was made.

"Expand the scope of the search, with the deep pit as the center, and expand to the surrounding area!"

After Chen Yan's order, Wang Gang and others also joined the excavation army.

Judging from the clues of the sharp knife just found, this is very likely the first scene where Qiao Shouhe was killed.

At least, it should be buried here!

Moreover, the murderer is obviously very cunning, and the body is buried very deep.

Everyone can get started with the surface excavation work.

In March, the ground in Liancheng was still frozen, and the temperature was very low under the deep pit.

But all the detectives were only wearing single clothes and sweating profusely.

Crack!

A light sound froze everyone's movements.

Chen Yan also showed a happy expression on his face.

This sound was very familiar to Chen Yan, it was definitely the sound of bones breaking.

"Captain Chen, a broken bone was found!"

Sure enough, a broken bone was found about one meter below the deep pit where the sharp knife was found!

Five minutes later, the broken bone was put into the collection box, and Chen Yan, Zhang Chaoyang, Wang Gang and others were all beside it.

"It's a rib!" Zhang Chaoyang recognized it as a human rib at first sight.

Chen Yan nodded: "Yes, judging from the shape of the bone, it should be the fourth rib."

Ribs, each one has a different shape.

Chen Yan has the autopsy skill specialization awarded by the system, and is very familiar with these experience skills.

With just one glance, he can tell which rib this broken bone is.

"And..." Chen Yan put on gloves and picked up the broken bone, observing carefully: "This rib has scratches."

"It means that the deceased was stabbed by a sharp weapon before his death."

Looking at the sharp knife next to the broken bone, Chen Yan picked it up and compared the scratched blade slightly.

"After doing a trace comparison later, we can confirm whether this sharp knife is a murder weapon."

This is relatively easy.

If the human skeleton is injured by a sharp weapon, no matter how many years have passed, there will be tiny metal residues on the bones.

Through chemical analysis and comparison, it can be determined whether the sharp knife found is a murder weapon.

After the ribs were found, many more bones were found one after another.

There was also a machete and a pair of pliers.

The entire excavation process took much longer than Chen Yan expected.

The murderer did not bury the body directly, but decomposed it first, and then buried it in different depths of soil.

The deepest point is about 3 meters deep.

The shallowest one was more than one meter deep.

After the excavation was completed, it was already noon on the third day.

Detective Team 2.

The detective in charge of the autopsy was named Wang Meng, who had completed the restoration of all the bones.

"Captain Chen, it can be preliminarily determined that the skeleton of this body is Qiao Shouhe."

On the dissection table, all the bones have been spliced ​​together.

But the forearm of the right arm is missing.

"This missing arm should be the one that Zhang and his son fished out of the pond five years ago."

"We have conducted a chemical analysis of the bones and there is no sign of poisoning."

"There are obvious scars on the back of the head bones, which should have been hit by a sharp weapon before death."

"From the items found at the scene, it should be the iron pliers."

"In addition, there are scratches on the ribs of the deceased. After preliminary trace comparison, it is the sharp knife found at the scene."

"And the machete has traces of curling the blade. By comparing the chopping marks at the bone joints, it can be determined that the murderer used the machete found at the scene to decompose the body and then buried it."

"Are there any other discoveries?"

Chen Yan pointed to the three murder weapons on the artifact table.

Sharp knife, iron pliers and machete.

"Is there any possibility of extracting fingerprints?"

Based on the current information, Qiao Shouhe's death must have been sudden.

So, the murderer is likely to leave clues when committing the crime.

If fingerprint information can be extracted from the murder weapon, it will be much easier to solve the case.

But Wang Meng shook his head: "It's been too long, and the three murder weapons have rusted."

"There's no way to extract fingerprints."

No fingerprints...

Chen Yan actually thought of it.

After all, it's been too long.

The three murder weapons have rusted and corroded, so it's normal that fingerprints can't be extracted.

But, in this way, the whole case has fallen into a bottleneck again.

After all, five years have passed, and it is undoubtedly very difficult to find the murderer based on a sharp knife, a machete and a pair of pliers.

But, having said that, the current situation is much better than just a broken arm at the beginning.

"But," Wang Meng paused and handed Chen Yan a report: "When we analyze the traces of the sharp knife again."

"There is an unexpected discovery!"
