Chapter 275 Fertilizer

Something is wrong?

Others were also a little puzzled.

Chen Yan circled around these trees several times.

There is nothing special about this dwarf forest, and there is nothing special about this piece.

The trees that Chen Yan circled around were a little taller.

None of the other dwarf trees were more than one meter tall, and these few trees seemed to stand out from the crowd.

Growing well, the trunk is thick.

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 it, and no one fertilizes it. It is a state of natural growth."

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

"Why is it taller than other trees?"

"This... it may be that the fertility of this field is better, so the trees are growing better?"

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

"But…"

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

"Is it... something is buried under the ground?"

Buried what?

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

"Team Chen!"

"You mean, Qiao Shouhe is buried here?"

"It's not certain yet, but..."

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

"it is good!"

Chen Yan's reasoning is not unreasonable.

This field is not much different from other places, but the dwarf trees are a bit 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 for detectives to carry out the excavation.

However, after half an hour of excavation.

"Chen team, this piece has been dug one meter deep, and nothing has been found."

not found?

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

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

Several detectives in charge of the excavation continued to swing their pickaxes, concentrated their strength, and digged deeply with the best growing tree as the center.

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

All present are the detectives of the 2nd Detective Squad.

It is the detective of the trace identification team who is in charge of the excavation.

Another quarter of an hour later, the depth was almost two meters.

But people still haven't found anything.

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

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

Five years have passed, and there are very few clues in the case back then.

Also involved in a traffic accident.

However, the present physical discovery has nothing but a severed arm.

Whether Zhao Dongfeng's confession is true or false, Chen Yan has no way of distinguishing the authenticity.

There is also no evidence that exactly what he said was true or false.

The same is true of Qiao Shanhe's confession.

Back then, there were only Qiao Shanhe and Qiao Shouhe in the car, and no one knew what happened.

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

Maybe the killer will be in...

boom!

A dull crashing sound interrupted Chen Yan's thoughts.

"Team Chen, Team Chen!"

"Have it! Have it!"

Under the deep pit, the detective shouted excitedly.

"What did you find?" Wang Gang was also excited, crawled on the edge of the deep pit, and shouted towards the bottom.

"It's a sharp knife!"

The crash, the crash between the digging pick and the metal.

The detective in charge of digging found a sharp knife underground!

Once found, you can no longer dig with a pickaxe.

Putting on the special tools for on-site investigation, the detectives below began to dig carefully.

However, after half an hour, nothing was found.

"Expand the range of Soso, with the deep pit as the center, and expand around!"

After Chen Yan ordered, Wang Gang and others also joined the excavation army.

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

At least, it should be buried here!

Moreover, the murderer is obviously very cunning, and the depth of the corpse is very deep.

On the surface of the excavation work, everyone can get started.

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

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

Click!

A light sound froze everyone's movements.

Chen Yan's face also showed joy.

This kind of voice, Chen Yan is familiar with, is definitely the sound of broken bones.

"Team Chen, found a broken bone!"

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

Five minutes later, the broken bones were placed in the collection box, with Chen Yan, Zhang Chaoyang, Wang Gang and others all on the side.

"It's a rib!" Zhang Chaoyang recognized at first glance that it was a human rib.

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

Each rib has a different shape.

Chen Yan has specialization in autopsy skills that are systematically rewarded, and is already very familiar with these experience skills.

Just at a glance, you can tell which rib this broken bone is.

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

"It means that the deceased was stabbed by a sharp weapon in front of him."

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

"Do a trace comparison later to confirm whether this sharp knife is a murder weapon."

This is easier.

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

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

After the rib was discovered, many more bones were discovered one after another.

There is also a machete and a pair of iron pliers.

The entire excavation process took a lot more time than Chen Yan expected.

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

The deepest point, about 3 meters deep.

The shallowest, but also more than one meter deep.

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

Detective Squad Two.

The detective in charge of the autopsy, Wang Meng, has completed the restoration of all the bones.

"Team Chen, it can be initially judged that the skeleton of this corpse is Qiao Shouhe."

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

But the forearm part of the right arm is missing.

"The broken arm that disappeared should have been caught by Zhang's father and son from the pond five years ago."

"We have done chemical analysis of the bones and there are no signs of poisoning."

"There are obvious scars on the back of the brain, because it should have been hit hard by a sharp weapon before dying."

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

"Besides, there were scratches on the rib of the deceased with a sharp weapon. After preliminary comparison of the traces, it was a sharp knife found at the scene."

"And the machete has traces of rolling blades. By comparing the slashing marks at the joints of the bones, it can be determined that the murderer used the machete found at the scene to decompose the body and then bury it."

"Any other discoveries?"

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

Sharp knives, tongs and machetes.

"Is it possible to extract fingerprints?"

Judging from the current information, Qiao Shouhe's death must have been sudden.

Therefore, when the murderer commits the crime, it is likely to leave clues.

If the 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 weapons have all rusted. UU reading "

"There is no way to extract fingerprints."

no fingerprints...

Chen Yan actually thought of it.

After all, too much time has passed.

The three murder weapons were all rusted and corroded, and it was normal that no fingerprints could be extracted.

However, as a result, the whole case fell 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 an iron pliers.

However, having said that, the current situation is much better than having only one amputated arm at the beginning.

"However," Wang Meng paused and handed Chen Yan a report: "When we do the trace analysis of the sharp knife again."

"An unexpected discovery!"
