Well?

Ren Qiang and Zhang Hui looked at each other, what is the situation?

They haven't asked about the specifics yet, so why don't they confess?

When!

The sound of pots and pans falling to the ground sounded in the back kitchen, and Chen Liu's daughter-in-law rushed out after him.

"Uncle policeman, the sixth son really didn't harm the Wang family!"

Chen's sixth daughter-in-law had a handful of snot and tears, and the nervous police uncle shouted out.

"Woooooooo......oo These gang of people who kill a thousand knives can't look down on our family...... Woo woo woo ...... "

"What did the six sons do when they kill their children?"

"You're going to have to call the shots for us!"

Looking at Chen Liu's daughter-in-law who was sitting on the ground, Ren Qiang and Zhang Hui were not helping, nor were they not helping.

"Chen Liu, let your daughter-in-law get up first."

"Things will be clear, what do you want, no one can wronged you without killing anyone."

"Really?"

Chen Liu's daughter-in-law's current expression doesn't seem to be very appropriate to describe it as pear blossoms with rain, but it is quite meaningful.

Ren Qiang sighed and replied, "Really!"

Chen Liu also got up and helped his daughter-in-law up: "What are you crying about!"

"Don't you know if I killed or not?"

"Go back to the back room!"

The woman glanced at Ren Qiang and Zhang Hui, and Nuo Nuo agreed to Chen Liu, and went back to the back room step by step.

Chen Liu smiled awkwardly: "Comrade policeman, I'm sorry, rural people have never seen the world, so I smiled."

"But I really didn't kill anyone."

"How did you know we were here to think you had killed someone?"

"Because on the day the child disappeared, the police station also came."

Chen Liutan spread his hands: "Like you, they also asked a lot of people in the village."

"Around the Spring Festival, I almost got into a fight with the people of the old Wang family because of the contract for the vineyard."

"They said that I had a grudge against the old Wang family, and that I hid the child when he lost it."

"In fact, I didn't want to buy the vineyard of the old Wang family at that time, the old Tian family in the west of the village, the old man Zhang in the east, and the old Dong family in the middle, I had to pass it."

"In that case, I have a lot of enemies, so you can't find me if anyone loses their child, right?"

"Now that the child is dead, and you come back and ask the same questions as the police station, I know that you must suspect the child I killed."

Ren Qiang listened quietly, did not refute, and did not ask any more questions.

"Chen Liu, the people in the tunzi said that you don't do your job properly and are idle."

Ren Qiang pointed to the car in the yard: "But I see that your family is in good condition, and you have cars."

"Oh, that's what my dad bought for me."

"Your daughter-in-law is pretty good-looking, too."

"Oh, daughter-in-law, my father gave me a wife."

"What did your dad do?"

"Village Party Secretary."

"And what do you live on?"

"By my dad."

Chen Liu's killing did not kill another person, and the villagers' evaluation of his idle words is not too wrong.

Leaving Chen Liu's house, Ren Qiang looked back at the door.

"To this Chen Liu...... What do you think?"

Zhang Hui shook his head: "I don't think he looks like a murderer."

"Oh? Is there any reason for this?"

Ren Qiang continued, "In the countryside, neighbors have lived for a long time and know each other very well."

"Let's go through this circle, many people say that this Chen Liu is suspicious and may be a murderer."

Zhang Hui nodded: "I know this, but because of this, I feel that Chen Liu is even less like a murderer."

"First, Chen Liu's conflict is not only the Wang family, but also several other families, and the relationship is also very stiff."

"Second, Chen Liu...... There is no motive to kill, he is just an old man, relying on his father in the village

As the village party secretary, he doesn't have to worry about eating and drinking, why did he kill the children of the Wang family, for money? Or is it to get angry?"

"I don't think it's reliable."

"Another point is that Chen Liu looks like a very shrewd person, he and the old Wang family almost got into a fight over the matter of land packing, and everyone in the tunzi knows it." ap.

"At this time, the children of the Wang family disappeared and died, and he must be the most suspicious."

"It's so obvious...... Isn't that too deliberate?"

Ren Qiang nodded in agreement, Chen Liu is suspicious, but there are too many places where this suspicion is untenable.

A lot of things that seem the most suspicious, but are actually the least likely.

Of course, there will never be a shortage of self-righteous people in the world, and on the contrary, there are not one or two people who make the lights dark.

Chen Liu is still the biggest suspect in the case of Wang Zihan's disappearance and murder.

At half past seven in the evening, it was already dark.

Survey Office.

Lu Chuan and the four are processing the physical evidence collected in the section where Wang Zihan disappeared.

Yang Sen originally asked for leave, but because of a murder, he rushed back in the afternoon.

"So much physical evidence?"

Looking at the several boxes of collection bags in the laboratory, Janssen had a tingling sensation on his scalp.

How long will this have to be analyzed?

"Put a few boxes here first, let's make these two boxes first."

The five physical evidence boxes in front are all filled with the physical evidence collected by several people at the beginning, and they began to collect it when they came out of Wang Zihan's house, and there are indeed more things.

But after changing the way of thinking and focusing on the distance after the turn, there is a lot less physical evidence.

"Xiao Lu, this is the physical evidence found in the place where the soil was renovated, the amount is not large, you have experience in the analysis of trace physical evidence, you operate these, and the three of us are responsible for several other boxes."

"Yes, Master."

Lu Chuan nodded, and what Liu Guodong handed him was a physical evidence analysis of the dander and similar fibers found near the renovated soil.

The amount of physical evidence is very small, but it should be said that it is the largest discovery of the scene investigation.

The first is DNA identification of trace amounts of dander.

Although Lu Chuan has not used the equipment of the trace evidence analysis laboratory before, he has experience in using the equipment in the intermediate field survey skills.

It's not very proficient, but it's not difficult to operate.

As for the fiber, Lu Chuan first separated a part of it and prepared to do a combustion experiment.

Fiber products look similar on the surface, but because of the different compositions, the performance during combustion will be very different.

For example, fibers such as cotton and linen, these fibers are mainly composed of natural cellulose, which is extremely flammable, and produces yellow and blue flames during combustion.

During the combustion process, this fiber also produces a unique odor, similar to the smell produced by burning paper.

However, the burning of wool, silk and other fibrous substances is actually the burning of proteins, and the burnt smell of burnt feathers will flow out, and the burning ashes will be spherical and crumbling when pinched.

In addition to the above plant cellulose and animal hair fibers, the most common fiber components are synthetic fibers, such as nylon fibers, polyester fibers and acrylic fibers.

In the process of purifying DNA materials from dander, Lu Chuan first carried out combustion experiments.

Soon, the results came in.

The separated fibers, when they are close to the flame, the edges shrink and burn, but they do not burn completely, and when Lu Chuan leaves the fibers from the flame, the edges are extinguished, and there is a smell of chlorine.

Lu Chuan suddenly realized that it was this fiber material!
