Things that solve crimes

Team Chen sighed, "Song Zhouyi's request is still the same. As long as we let him go out and take care of his mother for a while, he will tell us who the murderer is."

A young detective glared, "Is this cover-up?"

The old detective next to him hit him on the head with a "slap", "What kind of cover is there? At most, it's just knowing and not reporting."

"Go back and memorize the legal provisions again."

The young detective covered his head and grinned. The villain in his heart was weeping with tears. How long will it take for him to memorize such a thick book?

Another criminal police officer said, "It's a pity that there are no legal provisions in the criminal law about not reporting knowledge." If there is, kill him.

"Are there any other clues?" He Ju asked.

Everyone looks at the sky and the earth, but they don't care about the situation.

Qin Henian lowered his head and flipped through Song Zhouyi's information, and found something strange. Song Zhouyi seemed to like going to the library.

"Look here, Song Zhouyi seems to like going to the library. Could it be that he and the murderer had contact here?"

Team Chen said, "We investigated this matter and found that when Song Zhouyi went to read a book, he always walked alone."

Qin Henian frowned slightly and rubbed a corner of the white paper unconsciously with his fingers.

For someone like Song Zhouyi, he didn't believe that he was just going to the library. Every move he made contained deep meaning.

Especially when he's laying it out.

Everyone was talking about it, but they didn't come up with the reason. In the end, He Ji could only say helplessly, "The meeting is dismissed."

After the meeting, Qin Henian came to the library of Yu City Prison.

Rows of bookshelves are neatly arranged, with books placed on them, and soft lights shine in the room.

Song Zhou recalled that there are two places where he most often sits when reading in the library, one is at the table and chairs in the center, and the other is by the window on the left.

Qin Henian sat on the chair in the center first. He looked up and saw that there were books all around. Then he stood up and sat down by the window on the left.

He looked to the side, his pupils shrank slightly, and he could see the door from here.

He carefully observed the surroundings again. It was very good. There was a blind spot for surveillance. So who was Song Zhouyi looking at here?

Qin Henian took out his phone and called Bureau He and told him what he had discovered.

The police screened out three suspects based on Song Zhouyi's time.

During the meeting, everyone gathered around the table to look at the information on the three suspects.

"Jingle Bell"

Qin Henian's phone rang suddenly. He took out his phone and saw an unfamiliar phone number on it. He hesitated for two seconds and answered the call.

"Officer Qin, I am Song Zhouyi's mother." Mother Song's kind voice came from the other side of the phone.

"What's the matter with you?" Qin Henian asked.

Mother Song said, "After you left, I recalled it again and found that the person who came to see me smelled like meat."

"Meaty smell?" Qin Henian was stunned.

"Yes, it's the smell of meat. My father used to be a pig butcher, and he always smelled of meat. I grew up smelling this smell since I was a child, and I won't admit it."

"Before, I would have recognized this smell immediately, but now, I'm old." Song's mother sighed.

"Thank you very much for the clues you sent." Qin Henian said gratefully.

Mother Song sighed softly, "My son did something wrong, and I don't want it to happen again."

After hanging up the phone, Qin Henian told everyone the clues Song's mother gave him.

Everyone's eyes lit up, rivaling the green eyes of the wolves at night.

Then their eyes fell on the second suspect's information.

Yang Li, a pork dealer who provides pork to the prison, has been providing pork to the prison six years ago. Although he is not a prisoner, he is familiar with the prison.

Theoretically, it was possible that he had contact with Song Zhouyi in a place where no one could see him.

After identifying the person, He Ju waved his hand and arrested him.

Yang Li resigned a month ago, reportedly due to family reasons.

The police rushed directly to Yang Li's house. The police knocked on the door "bang bang bang", but there was no movement inside.

He Ju looked at Captain Chen and just knocked on the door.

Captain Chen looked at where he was looking and what he was bumping into. This was a security door. Can it be broken open?

Seeing the conversation between their eyebrows, Qin Henian fell silent. These two people still have this skill.

"Bang, bang, bang," the police officer continued to knock on the door without giving up, but there was still no movement inside. The one who did move was the resident next door.

"Squeak!" The door to the next door opened, and the grumpy old man yelled, "Knock on what? Are you disturbing the residents? Believe it or not..."

Before he finished yelling, he looked up and saw a row of blue clothes. The old man was startled and smiled awkwardly, "Officers, what's the matter?"

Qin Henian's heart moved, "Where have the people from the next door family gone?"

The old man glanced at the door next door and said, "I left early."

"Leaved? When did you leave?" He Ju smiled, looking hideous.

The old man was frightened and took a few steps back. This expression? Is this really the police?

Team Chen took out his police officer ID card and waved it in front of the old man. The old man still hid his body behind the door and said, "I left a month ago."

"I happened to meet him when I came back from the night shift a month ago. He was carrying a travel bag. I asked him what he was going to do. He said he was going to travel."

Qin Henian has been thinking about the turning point of the murderer from an ordinary person to a serial murderer.

Now after hearing this old man's words, he had an idea.

He learned from Yang Li's information that Yang Li loved his wife Wang Yan very much and was very attached to Wang Yan when he was not working. He wished they could become conjoined twins.

How is it possible that Yang Li, who likes Wang Yan so much, would leave Wang Yan and go traveling alone?

Wang Yan disappeared a month ago. A bold guess is that Wang Yan is probably the No. 1 victim in this case.

After knocking for a long time and no one came to open the door, Bureau He simply called a locksmith to open the door.

When they opened the door and saw the scene inside, everyone's expressions instantly became serious.

The sun shines into the house as the door opens, and everyone standing at the door is silent.

Everything from the door to the inside was stained with blood. Because it had been a long time, the blood had dried up and turned a little black.

"Mom!" The old man who peeked at this scene through the gap screamed strangely, ran home and closed the door.

No one at the scene paid attention to him, and now everyone's thoughts were on the blood stains in the room.

After setting up the cordon and leaving some people outside, Qin Henian and Team Chen put on their gloves and shoe covers and entered the room.

Qin Henian squatted down and looked at a series of blood stains.

"The blood stains spread from the door to the bedroom. Judging from the appearance of the blood stains, the victim should have been dragged from the door to the bedroom."
