Siheyuan: Seventeen-year-old He Yuzhu

"Captain, there's something going on here."

Xiao Li's voice came from outside the courtyard, and Bai Ling immediately went over to check.

She saw a few drops of blood on the ground outside, in the opposite direction of the hospital. This meant that they were not left by Liu Haizhong, but must have been left by the murderer.

Bai Ling became excited; this was a clue.

"Xiao Li, bring a few people with me to search along the blood trail."

"Xiao Lin, continue to question and see if you can determine the identity of the murderer. He must have a grudge against Liu Haizhong. We can put more effort into this aspect."

"Yes, Captain."

Bai Ling, Xiao Li and five other people followed the bloodstains to search, and the bloodstains led directly to the outside of the city.

She was a little worried. If the murderer really left the city, the situation would be difficult to deal with. At least he would not be caught for a while.

No one can guarantee whether such a vicious criminal will attack others.

When a person is pushed to a certain extent, he can do anything.

Bai Ling, Xiao Li and others stopped on a bridge. They could no longer find any bloodstains here, and if they went any further they would be out of the city.

They were very sad.

At this time, Xiao Li said:

"Captain, there seems to be some movement under the bridge?"

Bai Ling listened carefully and found that there was indeed some movement.

She gestured, asking everyone to be careful, not to make any noise, and to go down and take a look.

Several people came under the bridge and saw a curled up person. He was not very tall and was covered with newspaper.

Xiao Li walked over cautiously, thinking that the man was a homeless person, and wanted to ask if he had seen anyone or heard any noise at night.

His foot stepped on a dry branch, making a sound. The man jumped up and backed away repeatedly.

When he saw the person in front of him was wearing a police uniform, he ran away without saying a word.

Bai Ling saw that this person was a child and should not be the person they were looking for.

She also felt that the child's figure looked familiar, as if she had seen it somewhere.

She shouted, "Child, don't run. We are police officers, not bad people. We want to ask you something."

The moment Liu Guangfu saw the police, fear filled his whole body. He dared not stop and used all his strength to run quickly out of the city.

At this time, Bai Ling also remembered, wasn’t this person Liu Guangfu from the Siheyuan?

He had been away from home for such a long time, and they had looked for him before, but there were no clues.

I didn't expect to meet you here today.

"Xiao Li, this person is Liu Guangfu, the kid who ran away from home before. You must bring him back quickly."

Xiao Li hurried over and caught up with Liu Guangfu soon.

Seeing that he couldn't escape, Liu Guangfu got hot-headed and actually attacked Xiao Li with a blade.

Xiao Li's hand was cut before he was able to hold Liu Guangfu down firmly.

Bai Ling also rushed over, "Xiao Li, are you okay?"

Xiao Li glanced at the cut on his hand, blood was already flowing out, "Captain, it's just a minor injury, it's okay."

He said to Liu Guangfu: "You kid, we are police officers, not bad guys, and you actually cut me with a knife."

Liu Guangfu struggled violently, "Let me go, let me go quickly."

Bai Ling picked up the blade on the ground and saw that it was stained red with dried blood.

Only the blade has new blood.

She thought of the wound on Liu Hai's neck, frowned, and felt that there was something wrong with Liu Guangfu.

Xiao Li asked, "Captain, what should we do with this kid? With what's happening to the Liu family right now, it's not appropriate to send him back."

Bai Ling said: "I suspect he is related to the case. Xiao Li, come with me to take him back to the police station."

"Xiao Zheng, you guys continue searching here and see if you can find any clues."

......

Back at the police station, Bai Ling questioned Liu Guangfu.

Finally, we learned from him that he was the one who did it.

Bai Ling was still very surprised after hearing this. Although she had guessed this before, it was still a little hard to believe.

The same is true for Xiao Li.

He even suspected that Liu Guangfu was lying in order to cover up the real murderer.

"Liu Guangfu, this is no joke. Tell me the truth. What's going on?"

Liu Guangfu said: "I just said it, I went back to Liu's house, cut Liu Haizhong's neck with a knife, and then ran away."

"I slept under the bridge all night, and I saw you when I woke up in the morning."

Bai Ling placed the blade on the table and asked, "Did you cut it with this knife?"

Liu Guangfu took a look at the knife and nodded, "Yes, this is the knife."

Bai Ling asked again: "Why did you scratch the neck of the fringe? Isn't he your father?"

Liu Guangfu said: "He is not my father. I have severed the father-son relationship with him."

"I cut him in revenge."

"He beat me all the time when I was little. I hated him, so I scratched him."

Bai Ling asked again: "Where did you get this blade?"

"How do you know where to cut someone's neck?"

Liu Guangfu said: "I got the blade from Brother Wolf, and I also learned how to cut the neck from him."

Bai Ling asked, "Who is Brother Wolf?"

Liu Guangfu looked at her and said, "Brother Wolf is Brother Wolf."

Bai Ling said: "You have been with him all this time."

Liu Guangfu nodded, "Yes."

"After I ran away from home, I left the city and was hungry for two days. Then I met a man who said he could give me food, so I followed him. Then I met Brother Wolf."

"He has a lot of people there who are about my age."

"He would teach us something, and if we couldn't learn it, he wouldn't give us food or sleep, and he would beat us."

"I learned how to cut my neck from him."

Bai Ling and Xiao Li both frowned. It was obvious from the sound that this Wolf Brother was not a good person.

"What did he teach you?"

Liu Guangfu said: "How to pretend to be a cripple, how to deceive children, how to steal things from bags, how to act pitiful and ask for money..."

The more Bai Ling listened, the more frightened she became. This was a criminal gang.

"Did you run away from them?"

"Correct."

"Do you remember where they are?"

Liu Guangfu thought for a moment and said, "I don't remember clearly, I just know they are in the south, three days' journey from here."

"There's a big willow tree at the door of their place. It's crooked. If we don't learn well, Brother Wolf will have people hang us on the tree."

Bai Ling asked a few more questions and then left the room.

Xiao Li asked: "Captain, do you think what Liu Guangfu said is true?"

"This, I always feel..."

Bai Ling said: "It should be true."

"Although I was quite surprised, what he said is completely consistent with what we know, which proves that Liu Haizhong was murdered."

"And Brother Wolf, didn't we know before that there was a criminal gang that specialized in exploiting children? But we didn't know much about their information."

"Now that I hear Liu Guangfu say this, it just makes sense."
