The road where Wang Zihan disappeared was lined with poplar trees that had not yet sprouted.
On both sides of the poplar trees are large vineyards, with cement pillars supporting the grape trellis extending in rows with a height of 1.2 meters.
At regular intervals there is a mound of soil, with grape vines underneath.
"Every year before winter, farmers here bury their grapevines in the soil."
Lao Bai was explaining to Lu Chuan why there were bumps in the vineyard.
"The winter here is cold. If the grapes are left outside, they will freeze to death in one winter."
"The soil can retain heat. The weather has been getting warmer these days. Farmers still have to dig out the grapevines from the soil bags before they sprout."
Lu Chuan nodded. He really didn't know this before.
Lao Bai's kind is called living for a long time.
"Along the roadside, look carefully at the footprints in the woods and in the fields."
Liu Guodong reminded Lu Chuan and Lao Bai: "The other party has the highest probability of taking action on this section of the road. Whether the murderer kills on the spot or kidnaps the child and leaves, there are only two ways to leave."
"The first is to follow the road towards Natural Village, and the second is to turn into the vineyard and leave in the grape field."
"The opposite direction is Wang Zihan's home. It's unlikely that the murderer will pass by the child's home when leaving there."
Lu Chuan and Lu Chuan nodded. This was also the focus that the two of them had been paying attention to since they just started investigating.
However, after walking for more than a hundred meters, I found nothing major.
The weather has been getting warmer recently, the snow has melted, and the soil in the vineyards is so muddy that you can leave a footprint if you step on it.
It can be easily discovered with the naked eye, but so far, Lu Chuan and others have not made any discoveries in this regard.
"It is unlikely that the murderer left the grape fields."
Lao Bai expressed his opinion: "The fields have been muddy these days. The murderer must have known that if he walked through the grape fields, he would leave traces."
"The other person is not that stupid."
"but……"
Lao Bai raised his head and looked ahead. There was still more than a hundred meters away, which was a right-angled bend. Turning around, he could see Natural Village.
"It was daytime when the child disappeared. It was just after school in the morning. If the murderer went towards the village, there was no way no one would see him."
People in the village generally get up early, and six or seven o'clock is already a good time to work.
"Not necessarily. If the other party is driving or has some tools, no one else can see the child being loaded into the car."
Lu Chuan walked along the roadside and carefully observed some details. Read the book
The three of them walked side by side. Lu Chuan and Liu Guodong were on both sides of the road, mainly observing the side of the road.
Lao Bai is in the middle of the road, mainly observing the middle of the road.
"Let's go through it first. After the child disappeared, the police and villagers searched for the child nearby, but they certainly did not conduct a detailed survey of the road."
Liu Guodong stared, not missing any detail: "No matter whether the murderer kills here or not, this is the most likely place where he and the child met."
"So, whether it's kidnapping or killing on the spot, the murderer can't leave no trace at all..."
Um?
Just as he was talking, Liu Guodong's eyes narrowed.
"What's wrong?"
Lao Bai turned his head and looked at Liu Guodong who suddenly became silent.
"look here!"
Liu Guodong walked forward quickly, squatted on the roadside, and pointed to the place where fresh soil was exposed on the roadbed.
"The soil here has a different color than other places, it's darker."
Lao Bai also squatted down and looked around: "The soil below has turned up."
"Bring the instrument over and take a look."
Liu Guodong learned about this road. Most farmers would drive when passing by.
Few people pass by.
There were dead grass on both sides of the road, and it really looked like no one was walking on it.
But here, the soil under the withered grass has turned up, which is obviously not a natural formation.
Lu Chuan brought over the ultra-wide spectrum on-site trace evidence search camera and took a look at it.
"There's something!"
There is a reflective object on the turbulent soil, and the instrument indicates that it is a kind of fiber.
In addition, there are some tiny dandruff-like substances.
"Take it back and test it."
Lu Chuan agreed and started taking pictures.
Physical evidence found at the scene must first be photographed at the scene before it can be moved.
This is the established process for collecting physical evidence.
A bit of skin flakes and some fibrous material may seem small, but if they are left by the murderer, they may be used to solve the case.
Collection efforts continue, and other groups are also moving forward.
"Did you drive to Beitun the morning before yesterday?"
Sun Jun's group has the largest workload, but it is relatively more regular.
The water supply range of each motorized well in the vineyard is fixed.
Well No. 3 supplied agricultural water for six nearby vineyards, so the murderer's dumping of the body could not have been intentional.
First he needs to know where the No. 3 engine shaft is.
There are two vineyard contractors in Nantun, one in Dongtun, and one in Xitun who need the No. 3 machine well for irrigation.
The other two are the Wang Zihan family and the Tanaka family.
These natural villages are named after their directions and are all within five kilometers of the well.
Beitun is the natural village that Wang Zihan passes through to go to school.
So, why did Zheng Jianghe, who was in Xitun, go to Beitun on the morning when his child disappeared?
"I'm going to get some fertilizer."
"Who can prove it?"
"My brother-in-law, I went to his house to pull fertilizer. I went there at around four in the morning and came back at around seven. His neighbors also saw me."
Sun Jun and a group of people checked all the outsiders who had been to Beitun on the day of the crime.
Investigate one by one and eliminate suspects one by one.
Chen Liuzi's home in Beitun.
"Hello, comrade police, hello, come in and sit down, come in!"
"Daughter-in-law! Make some tea for the police comrades!"
After visiting most of the residents in Beitun, Ren Qiang and Zhang Hui finally came to Chen Liuzi's house.
Chen Liuzi, the sixth eldest son in the family, was named Chen Liu by his father.
"No need to bother, we'll check some things with you and then leave."
Zhang Hui waved his hands with a businesslike expressionless expression.
The smile on the enthusiastic Chen Liuzi's face froze: "Ah, it's okay if you don't drink tea... Then give the two policemen some water!"
Chen Liuzi's daughter-in-law looked young and very pretty. She looked nothing like the other farm women Ren Qiang and his wife had just seen in the village.
Chen Liuzi also looked young, and he didn't look like he had been doing manual labor for a long time.
People in the village said that Chen Liuzi was idle, which was not bad at all.
But when Ren Qiang just walked in, he saw that Chen Liuzi's home was well furnished, clean and tidy, and there was a car worth hundreds of thousands parked in the yard.
The living conditions are much better than most families in the countryside.
"Chen Liu, I hope you can answer our next questions truthfully and actively cooperate."
"Don't worry, don't worry, I will definitely cooperate, I will definitely cooperate!"
"The morning before yesterday, between six o'clock and eight o'clock...where were you?"
Upon hearing this question, Chen Liu's eyes paused slightly, and then his face fell.
"Comrade police, let me tell you, I really didn't kill the Wang boy!"
"They are all spreading rumors! They are all lying to them!"
