This time, it turned out to be a second-level enhancement of hearing.

**********

"A worker in the pig farm is now in the dormitory, and our people are taking transcripts."

After Chen Yan nodded, he did not go directly to see the worker who called the police, but instead observed it everywhere.

There is only one crusher in the northeast corner of the mixing room. The crusher outlet should have been an open space, but it has now been covered with blood.

After the entrance of the crusher, there are a pile of blocks of beans, as well as some corn and feed.

The crusher should be used to stir bean cypresses.

The ground was clean, made of cement, obviously cleaned, without any feed residue.

The door is open and surrounded by open vents and no windows.

"The murderer should have moved the body from here."

Wu Zhiguo pointed to the vent next to the crusher: "According to the workers in the field, the door of the mixing room is usually locked. When they opened the door in the morning, they found no abnormalities. There were some blood stains on the vent, and the murderer should be

From here, transport the body in and then in the crusher…”

Walking into the vent that Wu Zhiguo said, Chen Yan took a closer look.

Wu Zhiguo's judgment should be correct. The vent is about one meter high, so it is easy for an adult to cross it.

"Go and go outside and have a look."

When he came to the mixing room, Chen Yan did not find footprints under the vent.

The entire site was covered with cement. The murderer did not leave any footprints, but there were still bloodstains. It should be left by Zhang Baoquan's body.

Following the bloodstain, Chen Yan came to the edge of the wall of the site.

The wall, which is about 20 meters long, has collapsed, with new bricks and sand placed next to it.

"The walls here collapsed a month ago due to rain. The pig farm is planned to be repaired at the end of this month."

Looking at the bloody spots on the edge of the wall, the murderer obviously entered the pig farm from here.

“Where does this road outside lead to?”

"This rural road is connected to National Highway 212 from you five kilometers away. On the left are pig farms. After you go out, you can link to another entrance to National Highway 212."

Standing on the road, Chen Yan watched from side to side, then squatted down and carefully looked at the traces left by the vehicle tires on the ground.

Because the ground is dusty, the tire traces left are clearer, but there are obviously many passing vehicles.

Various tire marks overlap and crush, leaving only the latest traces of passing the vehicle.

"Are there any surveillance cameras on this rural road?"

"No, there are only cameras on the Ring Road nearby, and there are no other places."

"Let's go and see the workers who reported the case."

...

Ten minutes later, Chen Yan pig farm workers' dormitory met the worker who called the police.

Some messy dormitories are filled with pungent smells heavier than outside.

On the ground, there were rubber shoes that were taken off and pants that had not been cleaned for a long time.

Pig farming is a hard job, especially this small pig farm with low automation.

More than a dozen workers went down the pigpen to struggle, and everyone had only one smell, that is, the smell in the pigpen.

However, perhaps because of the long working hours here, the middle-aged man opposite Chen Yan had long been accustomed to this smell.

At this moment, the man was holding a cigarette butt that was about to be burned between his fingers, his hands trembled slightly, his lips turned purple, and his face was pale.

Even in the summer, I was wearing a cotton jacket, which was obviously scared.

"Captain Chen, you are here."

The detective who was responsible for taking the transcript stood up and saluted, and Chen Yan waved his hand: "Is there any progress?"

The detective who was in charge of recording the confession shook his head: "No progress has been made, he was too nervous and said nothing."

Chen Yan said oh, regardless of whether the stool was dirty or not, he sat opposite the middle-aged man and handed the man a cigarette: "Master, don't be nervous, my name is Chen Yan."

"How many years have you been here to work?"

ah?

Subconsciously taking the cigarette from Chen Yan's hand, Wang Kun was stunned for a moment, as if he had just come back to his senses.

Bang!

The lighter lit sound pulled Wang Kun back from his fear. He held the flames with his trembling hands and lit the cigarette: "Thank you, I've been here in this pig farm for three years."

Chen Yan didn't say anything, and he also lit a cigarette: "Is the master from Liancheng?"

Seeing Chen Yan smoking with him, it seemed that he had pulled the distance between the two of them, Wang Kun's face relaxed slightly: "No, I am from the rural area of ​​Tie City."

"A relative introduced me to me. Raising pigs at home does not make money, so I can at least save a little here."

"Come on, master, smoke another one. This is the good cigarette I came from our leader..."

Maybe Chen Yan's words diverted Wang Kun's fear, maybe Bao Huazi played a role.

After more than ten minutes, Wang Kun's condition obviously recovered.

“It was 9:30 this morning…”

Although the scale of this pig farm is not particularly large, there are 2,000 pigs.

Raising pigs does not mean that you can just feed these pigs.

It also needs to meet pig house breeding standards, such as sanitation and disinfection, epidemic prevention and injections, etc.

There are 12 workers in the farm, in groups of four, divided into three shifts, responsible for all the work in the pig farm.

This week, Wang Kun's team was responsible for crushing food and cleaning the pigpen, while the other two teams were responsible for feeding pigs.

"Today we are going to crush all the three tons of beans in the mixing room and stir them with corn, but we didn't expect..."

Although Wang Kun's emotions have stabilized a lot, he is still afraid when he mentions the crime scene.

This is a normal reaction for ordinary people. Not to mention Wang Kun, a pig farmer, even Zhang Yunhu, who just saw the scene in the mixing room, almost vomited it out.

How come this is a murder?

"Master Wang, the starting sound of the crusher should be quite loud. Didn't you hear anything abnormal at night?"

Although the mixing distance is far from the dormitory, the starting sound of the crusher should be relatively loud, especially in the middle of the night. If the crusher is started, there is no reason for them to not hear the sound.

"Last night, I did hear a little noise, but everyone was so tired during the day that they didn't care at all."

"When we woke up in the morning, we cleaned the pigpen first, and then went to the mixing room to work."

"I went first because I had to prepare the materials in advance, but the result was..."

"Do you remember the approximate time when you heard the movement?"

"I don't know when I was confused and vaguely heard the sound."

The information provided by Wang Kun is very limited.

In fact, apart from Wang Kun, several other workers also said that they could hear some noises.

But as Wang Kun said, these workers have a lot of physical labor during the day, are very tired, and sleep very hard at night.

Although I heard some movement, I didn't care.

"Captain Wu, notify colleagues to collect residual substances at the scene and do DNA testing and comparison."

"yes!"

Conference room of the third team of detectives.

Chen Yan is presided over a case analysis meeting.

Liu Qingshan, Zhang Chaoyang and other members of the serious crime team have been present.

Now, it can be confirmed that this is not a simple traffic accident.

The body of the deceased disappeared and was found to be crushed in a pig farm crusher.

Why?

The most typical destruction of corpses.

The reason why the murderer did this must be because he left something on the body of the deceased and did not want to be found by the police.

So, after the car accident, the murderer smashed the body.

"Captain Wu, let's report on the current situation."

"yes!"

Wu Zhiguo stood up and reported the clues that have been investigated: "At 8:20 this morning, the third team received a call and a serious traffic accident occurred at the intersection of the North Ring Road in the City and National Highway 212."
Chapter completed!
