Under all kinds of advanced equipment, all the biological traces on this road basically can't escape the investigation of the three people.

Not a single feather, or even a little dander, could escape the scanning of the instrument.

But if this continues, it will lead to too many things collected by Lu Chuan and others.

No, not even twenty meters from the vineyard, hundreds of biological traces have already been found.

Liu Guodong frowned and shook his head: "These things are easy to use, but it's not a way to go on like this."

"With this amount of work, we can scan the two-kilometer road without eating, drinking, or sleeping, and we won't be able to finish it in more than ten days."

"There are so many samples, and we don't have the manpower to analyze and verify, so we have to think differently."

"I think so," Lao Bai thought about it, there are only a few people in the current investigation office, and if so many samples are returned, they will not be able to analyze it at all in a few months.

"When the child came out of the house, it was a straight line about 300 meters ahead, and this direction looked clear."

"Whether the murderer is a temporary murder or a premeditated murder, there is a high probability that he will be in a place where no one is secret."

"The 300-meter straight line is too close to the child's home, and the child's parents can easily find out."

"There are more than 400 meters in the second half, which is also a straight line into the natural tun, and if the child calls for help, it is easy to attract attention."

"I think we should focus on the corners," Bai drew a diagram on the ground.

"This section of the road, which connects the straight line into the natural tun and into the child's house, is a section of the folded road, and there are trees around it, and the murderer is most likely to do it here."

Lu Chuan nodded first: "I think it's also the focus on this."

Lao Bai's analysis is very reasonable, this distance is the most suitable for hands-on.

Liu Guodong also nodded: "Okay, then let's make sure that the distance of three hundred meters is the key."

However, the trio did not completely abandon the 300-meter distance in the early stages.

It's just that instead of irradiating with an instrument, you use your eyes to observe.

In Haizhou in March, although the weather is warmer and the snow is melting, the trees have not yet budded.

The poplar trees on both sides of the road only have branches, which looks a little bleak.

The first half of the road didn't make any special discoveries.

After the child went missing, parents and police have already searched for several times on this road.

But nothing was found.

Turning the corner, Liu Guodong turned on the instrument: "From here on, don't let go of any doubts."

The suspicions mentioned by Liu Guodong refer to the characteristic traces left by people.

Like footprints, like hair.

Marks that are clearly left by animals, such as feathers, are not taken into account.

When the survey began to work, the work of the action team led by Sun Jun and Ren Qiang also made progress.

"Our family has been contracting vineyards here for ten years, and we don't have any enemies."

Wang Zihan's father was in his thirties, with dark skin, and because of his perennial work, the wrinkles on his face were very deep, and he looked like he was fifty years old.

At this moment, the man's eyes were hollow, squatting on the ground and smoking, his eyes were blood-red, but there were no tears for a long time.

"Mom, when will my brother come back?"

On the kang next to him, Wang Zihan's mother hugged her three-year-old daughter and sobbed silently.

"We used to live in the tunzi in front of us, but in order to take care of the grape trellises, we move out every spring, and the other families in the tunzi also live in the tunzi in the winter and move out in the spring."

"Who has had a financial dispute with your family before, or has there been a neighborhood conflict?"

"Yes! Why not!"

The man didn't speak, and Wang Zihan's mother spoke: "It must have been Chen Laoliu who did it, he killed a thousand knives, he couldn't contract the vineyard, and he held a grudge, he killed my son!"

"Shut up!"

The man scolded the woman: "The police are here, what are you talking nonsense!"

"Woo

Woo...... How can I talk nonsense, Chen Lao Liu also had a fight with you last year, you forgot!"

"It must be him!"

Ren Qiang and Zhang Hui glanced at each other and secretly remembered the name.

Naturally, Ren Qiang is visiting every household.

"You said Chen Liuzi, that is a scoundrel, the vineyard contract in the village expired last year, and he wanted to contract the vineyard of the old Wang family."

"Everyone has been planting for ten years, and they have invested in it to make some money, how can Chen Liuzi want to pick up a bargain."

"When he contracted the land last year, Chen Liuzi found fault and fought with Lao Wang's family."

"The children of the old Wang family are gone, I think Chen Liuzi probably won't be able to run......

The aunt of the Zhang family was extremely suspicious of Chen Laoliu.

Aunt Sun: "Chen Liuzi? If you don't do your job, you're afraid of killing chickens, and I don't think the child has anything to do with him."

"Before the Chinese New Year last year, there was actually no fight, but after a few pushes, it was pulled away, and I was at the scene."

Naturally, there are only more than 70 households, most of which grow grapes.

Ren Qiang's group of twelve people, divided into six groups, went door-to-door to understand the situation.

"Chen Liuzi...... I don't think it's likely."

Tunzi west to the side, the person who lives is called Tanakafa, Wang Zihan used to go to school, the first thing he passed by was his house. Look at the book

"I went to work early every day, and I didn't pay much attention to the old Wang boy that day."

"Chen Liuzi has nothing to do with the old Wang family, it is the matter of contracting vineyards, and he also wants to do it in other people's families, not only the old Wang family."

Tanaka is accustomed to smoking dry cigarettes, so he rolled up his cigarettes: "My vineyard is next to Lao Wang's house, and Chen Liuzi also looked for me a few years ago, and I kicked him out."

Zhang Hui listened while taking notes, and when he was leaving, he saw a padlock on one side of the wing, and something seemed to push the door inside.

"...... here"

Tanaka's face froze: "I'm sorry, it's my daughter-in-law, I'm not in good spirits, I have to lock her up when I go out to work."

As he spoke, Tanaka took out the key and opened the door of the wing, revealing a figure with a disheveled face and only two rows of white teeth.

"I'm smiling."

Tanaka is used to it, but he feels that outsiders are a little embarrassed to see his mentally ill daughter-in-law.

Turning to the inside, he said, "I'll have lunch later, don't worry."

As he spoke, he re-locked the room.

Zhang Hui shook his head, he was also from the countryside, and in his impression, it seemed that there were people in every village who were not in good spirits.

Not much, just one, although the mind is not clear, but the body is surprisingly good.

Even though they eat averagely, they usually live a long life.

The old man said that this is the person who protects the village from disasters, and with them, the village is smooth and rainy, and there is no disease and no disaster.

Shaking his head, Zhang Hui knew that this was superstition.

More than 70 households and six groups of people can be investigated in less than a day.

The situation on Sun Jun's side is more complicated.

The western suburbs have a large vineyard area, which is suitable for grape growth due to humidity, temperature and other reasons.

Residents in the neighborhood rarely go out to work, and they all grow grapes at home.

Centered on the No. 3 machine well, there are 12 natural villages within a five-kilometer radius divided by Qin Yong.

It is very difficult to investigate thoroughly.

On the other hand, when it was close to dark, there was a major discovery.
