God of unknown origin, please don't ask [criminal investigation]

He was lying on the bottom of the bed with his hips pouted, and he took out a long hair with tweezers and put it into the evidence bag.

"The long black hair does not belong to the two victims." Wen Xichun said softly, "Take it back for a DNA test, and we will go to the family's house at the end of the village later."

Huang Jiu: "Which one?"

Wen Xichun took a deep breath: "The one that can cook beef for you."

Huang Jiu:? ? ?

There are not many residents in Chongmen Village, only a hundred or so households, but there is only one household at the end of the village near the forest.

The psychotic boy and the man in disguise.

When the police passed by, the little boy was still wearing old clothes, squatting at the door of the house with his knees hugged, his head buried in his trousers, his whole body hugged into a ball, looking like a weak and boneless soft slug.

"Xiaoyong?" Hearing his adoptive mother, oh, it should be said that his adoptive father called his name, Wen Xichun followed suit.

The little boy didn't respond at all, he was just immersed in his own world and couldn't extricate himself.

Behind him is a low brick house, with a large piece of wall skin peeled off, revealing the red bricks inside, and white couplets pasted on the old wooden door.

"Xiaoyong, is your mother at home?" Wen Xichun did not give up, and asked again tentatively.

The little boy still maintained that action without speaking.

Yao Jingrong cleared his throat, and signaled him with his eyes not to be doing useless work, and just went in to have a look.

The inside of the brick and tile house looks more dilapidated than the outside. It looks as simple as an old shack. A clothesline is pulled up in the yard, and the clothes in black and gray tones are drying on it, which is quite clean.

A pair of tattered men's boxer briefs with frayed edges hung in the middle. Judging from the size, they did not look like a boy's clothes.

The curtain at the door of the house was suddenly pulled open, and a "woman" wearing a gray-blue coarse cloth jacket slowly came out of the house.

Seeing a few policemen standing in the yard, she was obviously taken aback, and took a few steps forward, intentionally or unintentionally blocking in front of the boxer briefs.

"You... What's the matter?"

The man's voice was very low, as if deliberately hiding something.

Wen Xichun showed him the police ID: "We are from the General Bureau of Criminal Investigation, and we are here for the murder of the Yuan family. I hope you can assist us in our investigation."

He hesitated for a while, then nodded slowly, and leaned aside: "Then please come in."

As soon as I entered the door, I found that the inside was very clean and tidy. There was a freshly prepared dinner on the table, boiled cabbage, diced radish and small pickles, a very simple dinner.

"We'll just ask a few simple questions, and you can answer truthfully, so don't feel pressured." Wen Xichun waved his hand, motioning for Xiao Liu to come over and take notes.

The man nodded, sat down slowly, and gently grasped the corners of his clothes with both hands. Even though he tried his best to conceal it, he could still see his inner gain.

"Name."

"Yu Xiurong."

"age."

"Two... 24 years old."

Wen Xichun raised his eyes: "24 years old is so old, when did you get married?"

"No, it's not 24...it's 34."

Wen Xichun shook his head with a cold smile: "Show us your ID card."

"lost……"

As soon as the words fell, almost everyone present looked up.

"Because I don't need it usually, and I have to go to the county seat for a replacement. It's too far away, so..." The reason given by this person is reasonable.

"Do you usually have men come over as guests?" Wen Xichun suddenly asked without beginning or end.

"No, no, why do you ask that?" Yu Xiurong clenched her hands tightly.

Wen Xichun raised his head and tapped the small wooden cabinet opposite with his chin: "Otherwise, I can't think of any other uses for the razor."

Suddenly, Yu Xiurong stood up suddenly, with a flustered expression: "Yes, I'm sorry, I'm going to take my son to dinner, otherwise please go back first."

Wen Xichun didn't force him, and took out the fingerprint collection book: "Well, you leave us a fingerprint, all ten fingers are needed."

"What do you want fingerprints for? How could this matter have anything to do with me? How could I have the strength to hang these two people..."

"No, it's a normal procedure. The fingerprints of other people in the village have to be collected." Wen Xichun's voice was cold, like the Antarctic permafrost, and the other little police officers who heard it whispered in their hearts.

Yu Xiurong sighed, slowly stretched out her hand, and pressed ten of her own fingerprints.

"That's fine, thank you for your cooperation, I'm sorry." Wen Xichun put away the fingerprint collection booklet, and saluted Yu Xiurong.

When going out, Yu Xiurong followed closely all the way out, his eyes flicking back and forth at several police officers.

Out of the corner of his eye, he suddenly discovered that there was a tall police officer who never entered the door and stayed in the yard all the time.

The one standing in the yard was none other than Yao Jingrong.

"What are you doing standing here?" Wen Xichun asked casually.

"It's fine if you're inside, and it's unnecessary for me to go in." Yao Jingrong smiled, but there was obviously a hint of malice in the smile.

Wen Xichun frowned slightly, ignored him, and walked out of Yu Xiurong's house.

Back in the police car, Wen Xichun didn't rush to start the ignition, but just sat silently in the driver's seat with arms folded and meditating.

The last survey site did not find long hair. After the man in the raincoat appeared, he had long hair. Think carefully about the figure of the man in the raincoat. He is about 1.7 meters and [-] meters tall, and his body is thin. See exactly what he looks like.

Is it Yu Xiurong?Or are there other possibilities in between.

"I found this thing in the corner of the yard of Yu Xiurong's house." While Wen Xichun was contemplating, Yao Jingrong suddenly handed over a SLR camera.

Wen Xichun took a look, in the middle of a pile of wood, there was a palm-sized iron circular object with three gears in the middle.

"This is... the roller shaft?"

Yao Jingrong nodded.

A scene suddenly flashed through Wen Xichun's mind.

When I was young, I went back to my hometown in the countryside. It happened to be the season of harvesting millet. At that time, I liked to go to the fields with my grandparents to play. After harvesting the millet, I filled a sack full of it and hung it in the cellar to prevent dust from falling. Fifty or sixty kilograms, it is not easy for two old people to lift up. Grandpa will install a small roller on the beam, and with a light pull, the millet will be hoisted onto the beam with ease.

Later, I asked my father, and my father said that such a roller would reduce the friction, the friction is small, and the gravity becomes greater, so even a thin person can lift tens of kilograms of millet.

Wen Xichun raised his eyes suddenly: "The victim was hanged by this Yu Xiurong?"

"He hung it up, but he didn't kill it. It's hard to say. After all, judging from the current situation, he has no motive for committing the crime." Yao Jingrong said.

"Indeed, it's impossible to kill the victim in such a cruel way just because he doesn't like it, and then hang him on the beam, and insult the deceased in a public way."

"If we talk about the motive of committing the crime, Ren Siyu is the most suspicious person. Judging from the footprints left under the bed, he is hiding under the bed. It is almost impossible to get on the beam."

"In this way, you send the fingerprints back to the trace inspection department, and ask them to compare the fingerprints found on the scene, and compare them to the fingerprint database to see if there is any match." Wen Xichun handed the fingerprint collection book to Huang Jiu.

However, this probability is very small, almost equal to zero, because most of the fingerprints collected in the fingerprint database are those who have committed crimes and spent time in prison, and then there are some people who have reported crimes or national public officials.

But some things are really uncertain.

After sitting in the police car for a while, I received a call from the trace inspection department.

"According to the comparison of fingerprints, the owner of the fingerprints is a 24-year-old man named Yu Rongxiu. His native place is Huiyuan. The brawl has been criminally detained."

"Fighting?" Wen Xichun repeated, "Send the information to my email, I'm sorry."

"What, what's the windfall?" Yao Jingrong put down the document in his hand, and shot his eyes.

"This woman... this man was once criminally detained for fighting. He dropped out of high school and has been unemployed."

"What does this explain?" Yao Jingrong asked with a smile, "Because he had a history of fighting, is this murder case necessarily related to him?"

"I didn't say it." Wen Xichun rolled his eyes at him, "As the saying goes, what the heart thinks, what the words say, don't you understand?"

"By the way, which high school did Ren Siyu go to?" Ignoring him, Wen Xichun turned to Xiao Liu.

Xiao Liu thought for a while: "It seems to be the No. [-] Middle School in the city. It's hard to say that the children of the □□ family can't get into the best high school in the city."

Looking at the information sent by the trace inspection department, Wen Xichun paused, and said softly: "Tomorrow, I will go to Shi No. [-] Middle School to find out the situation with the teacher from that year. Whether he and Ren Siyu knew each other, and why they dropped out of school."

Wen Xichun had a hunch that they were slowly approaching the so-called truth, only one layer of window paper was missing, and as long as they pierced through this layer of window paper, they could get the answer they wanted.

Although it was late, a group of people insisted on going back to the police station. Fortunately, they were familiar with the road and entered the boundary of Huiyuan city in only three hours.

At nine o'clock in the evening, everyone in the car was asleep on their backs. Even Yao Jingrong gave up struggling and dozed off with one hand on his forehead.

"Wake up, we're here." Wen Xichun patted the rear seat, his eyes were bloodshot.

Several people rubbed their sleepy eyes, looked at the dark night sky, said "Thanks for your hard work" to each other, and opened the door to get off.

"Wait." As soon as they stepped out of the car, they were stopped by their Wen team.

As soon as he turned around, he saw Wen Xichun nodding his chin to Yao, who was sleeping like a dead pig in the co-pilot.

"Oh, team Wen, aren't you good brothers and good friends? You can handle it and send it home." After Huang Jiu finished speaking, he slipped away in an instant with oil on his feet.

These people are active after get off work.

Wen Xichun glanced at Yao, who maintained an elegant posture even when he was sleeping, rolled his eyes, and raised his hand to push him: "Wake up, the sun is shining."

Yao Jingrong didn't move, only a slight breathing sound responded to him.

"You pretend to be asleep." Wen Xichun said so, but honestly raised his hand to check Yao Jingrong's breath.

Well, still alive.

"Then you sleep in the car, I'm leaving." After turning off the ignition, Wen Xichun pulled out the car key, opened the door and got out of the car.

The stars are little by little in the sky, which is a scene that is difficult to see in the city.

Wen Xichun didn't take two steps, but Wen Xichun hesitated and slowed down, and gradually, he stopped.

He turned around suddenly and walked back quickly.

Open the car door, help Yao Jingrong unbuckle his seat belt, wrap his hands around his waist and drag him down the car——

Yao Jingrong seemed to be dying when he was sleeping, even Wen Xichun stretched and flattened him, but there was no response, and he even tilted his head consciously, into Wen Xichun's arms.

"No matter how I think about it, I feel that you are faking it." Wen Xichun simply carried him on his back, intending to carry him into the duty room and let him make do with it for the night.

But Yao Jingrong was a full head taller than him. Although he was not fat, he had a heavy frame. Wen Xichun felt that he had carried two sacks of cement rather than a person.

After finally being carried into the police station, he turned the doorknob of the duty room——

Who was so zealous to lock the door?

Forget it, there is no other way, the cement can only be carried home.
