Everyone in the conference room, including Chen Yan, was smoking cigarettes with sad faces.

The case this time is a bit tricky.

The first is the scene where the body was found.

The murderer decomposed the body and threw it into the mixing station, and then sent it to two construction sites via concrete mixer trucks.

After being covered with concrete and stirred by a mixer truck, no traces of the murderer were left on any of the bodies.

Now, the role of the corpse is to determine the identity of the deceased and the time of death.

More wreckage has been found at the construction sites of Kangmingyuan Community and Wanghai Building, but it is becoming increasingly difficult to find them.

Because the concrete mortar poured in advance has begun to gradually solidify.

Even if something is discovered, it will be difficult to dig it out.

In addition, judging from the injuries on the remains discovered now, it can be judged that the other party used an ax to decompose the body. However, because the number of remains found is not large, there is still no way to determine the specific cause of death.

Now, the investigation on the interpersonal relationship between Tao Lin and Zhang Suosuo is basically complete. All the people who have emotional entanglements and interest entanglements with the two people have been found.

Logically speaking, the ones who have the most reason to attack are Zhang Suosuo's husband Chen Pei and Tao Lin's younger brother Zhang Baoqiang.

However, Chen Pei was sure that there was no time to commit the crime. Although there was no witness on Zhang Baoqiang's side to prove that he was at home last night, according to the memories of his neighbors, Zhang Baoqiang should not have gone out after returning home the night before yesterday.

Zhang Baoqiang’s neighbor is a 70-year-old man. He is getting older, goes to bed late and gets up early, and the sound insulation of the old building is not good.

According to what the old man said, Zhang Baoqiang can hear it every day when he comes home and goes out.

The night before yesterday, Zhang Baoqiang's schedule was the same as usual, nothing special.

"In this way, Captain Wu will send people to search Zhang Baoqiang's residence to see if any suspicious points can be found."

"Okay, I'll make arrangements right now."

"Chaoyang, is there any progress in the re-examination on the driver's side?"

"I kept watching over there last night and personally questioned 12 drivers, but there was nothing unusual."

"When I came back in the morning, Wang Gang and Zhao Bing stayed there."

driver

Chen Yan frowned.

Going back to the original question, that is how the murderer entered the yard of Yuanfang Commercial Concrete Company. There were so many commercial concrete companies in that area, why did the murderer choose Yuanfang Commercial Concrete Company.

Also, you can be sure that the other party did not come in carrying a body.

Most likely he was driving, but why didn’t the driver’s investigation show anything unusual?

The old gatekeeper said that he saw no strangers enter that night, and the only vehicles were the mixer truck and the boss's car.

Yuanfang Commercial Concrete Company has no dealings with Zhang Suosuo or Tao Lin.

Although the mobile phones of the two were not found, the call records can be found.

No one in the distant concrete business had any contact with these two people.

"Chaoyang, come with me to the Yuanfang Commercial Concrete Company again!"

Now that all other clues have been lost, Chen Yan decided to personally follow up on this clue that has not been discovered so far.

Buzzing.

"What did you say? Necklace!"

On the way to Yuanfang Commercial Concrete Company, Chen Yan received a call.

"Chaoyang, turn around and go to Kunlun Road!"

Zhang Chaoyang immediately turned around and accelerated towards Kunlun Road.

Kunlun is a street that has just been built and is almost uninhabited. However, it is not far from the Yuanfang Commercial Concrete Company in the northern suburbs, only six or seven kilometers away.

When Chen Yan arrived, Li Yun from the fourth team was waiting at the scene.

"Team Chen, we made a discovery!"

Walking off the roadbed, there is a roadside protective forest and grassland next to it.

A cordon has been set up at the scene.

"Team Chen, two young men herding sheep just called the police and found this bloody necklace."

Two young men herding sheep?

"They didn't keep the necklace for themselves?"

Li Yun smiled bitterly: "The two of them almost thought they were going to fight..."

Chen Yan: "..."

human nature

The cordon was opened and Chen Yan walked into the center of the scene.

A bloody necklace fell into the grass.

Chen Yan was shocked when he saw the necklace for the first time!

This necklace... looks a little familiar.

Squatting on the grass, Chen Yan put on his gloves and gently picked up the necklace. He found that it was made of pure gold and was quite heavy.

An agate pendant is embedded in it.

A photo suddenly popped into Chen Yan's mind.

Yesterday, he saw this necklace!

"Chaoyang, send the photo that Tao Lin projected yesterday!"

A minute later, Chen Yan carefully compared the necklace in his hand with the necklace on Tao Lin's neck in the photo. Zhang Chaoyang also saw that the two were exactly the same.

"This is Tao Lin's necklace!"

Gan!

How could the necklace belonging to Tao Lin appear here?

The grass on the roadside of Kunlun Road in the wilderness!

"Check around and see if you find any blood!"

Wu Zhiguo and others immediately searched the surrounding area, which took less than ten minutes.

"Team Chen, there is something discovered here!"

A hundred meters away from the roadside, in an abandoned water pump house, two detectives shouted loudly.

puff!

When I opened the small door of the water pump room, the strong smell of blood hit my nostrils.

Chen Yan frowned and looked at the blood sprayed everywhere inside.

There are still some fragments of bones and slag left on the ground.

The first crime scene was finally found.

The detective responsible for on-site investigation immediately collected evidence from the scene.

In the corner, a bloody ax attracted Chen Yan's attention.

The ax head is very old, but the edge is still sharp. At this moment, it is dark red because it is stained with too much blood.

This should be the tool used by the murderer to chop up the corpse.

The investigation in the water pump room was quickly completed. There were no fingerprints. It was obvious that the other party wore gloves when committing the crime. However, more than a dozen messy footprints were extracted.

Because the ground has been stained with blood, many footprints are very clear.

The investigation of the case finally made important progress.

Kunlun Road...

Chen Yan walked out of the water pump room and looked outside at the road that had just been built not long ago.

This road is sparsely populated, and according to the young sheepherder, no one usually comes to this place.

There are rice fields on the side of the road, which are growing vigorously now. There are only people here when they are planting rice in spring and harvesting grain in autumn.

What's left is that he occasionally passes by here while herding sheep.

However, many concrete mixer trucks pass by this road.

Although this is not the only way to enter the city from the northern suburbs concrete mixing station, and is even farther than the route they usually take, there are few vehicles and there is no need to queue.

Therefore, many mixer trucks will pass by here.

So, the people who killed Tao Lin and Zhang Suosuo

The goal is already very clear.

Yuanfang Commercial Concrete Company.

Chen Yan personally investigated the situation of the driver transporting concrete that night.

All 12 drivers were present.

"There was nothing unusual that day. I transported a total of three trucks of mortar that day. When you went there in the morning, I watched the excitement for a while and then went home."

"I didn't notice. Most of us who transport mortar work at night and early in the morning. During the day, our kind of vehicles are not allowed to enter the city, so we can only work at night. We just went about our work and didn't notice any suspicious people.

.”

"I don't know. It's normal when I pull mortar. You'd better ask the janitor, Lao Zhangtou." Chen Yan asked 12 people one by one.

Chen Yan turned on micro-expression analysis for everyone, but these people didn't have any flaws.

Some of the 12 people are familiar with each other, and some do not know each other.
Chapter completed!
