A day later, Tian Chunda announced the identification of Liu Ye's body and on-site evidence by the technical appraisal room in the serious case group:

"The hair found at the scene was a male pubiculation. The hair, most likely rubbed off by the suspect during the rape of the victim.

Tie the shoelaces of the deceased, which are the laces of the boots. Blue paint was also found on the laces, which was a single layer of paint used in the family home, and the paint was very new after the paint flakes were tested, so it was inferred that the murderer had done paint work shortly before the crime.

Yin from the dead. The part of the liquid was taken and the essence was found. Child. Laboratory analysis revealed that the suspect's blood type was B. Residual sperm. enzyme analysis was carried out, and the results were also obtained. He added: "I found a single-edged knife in the bushes, and there were still some blood marks on the blade. The blood stains on the knife are consistent with the blood type of Liu Ye, and the blade is also the same as the knife marks on Liu Ye's body, so it can be determined that this knife is the murder weapon that killed Liu Ye. ”

The police and criminal police at the police station followed Tian Chunda's instructions and went door-to-door near Nanshan to find newly painted doors and windows.

Hao Dong approached an old house on the edge of the forest, and his eyes lit up, and he saw that the doors and windows of the house had been painted with blue paint not long ago.

Hao Dong stepped forward and knocked on the door. A man in his sixties opened the door.

Hao Dong showed his ID to the old man and said, "I'm a policeman." ”

The old man looked at the documents, then at Hao Dong, and asked, "Is there anything wrong with you?" ”

Hao Dong asked: "Old man, your doors and windows are newly painted with blue paint, right?" ”

The old man nodded: "Yes." It's paint that was painted half a month ago. ”

"Did your family brush it, or did you hire a worker to brush it?"

"I hired a worker to brush it."

"What's the name of this worker? Where to stay? ”

"His name is Luo Jian, and he lives around here." The old man pointed to a house in front of him.

"How old is he?"

"Twenty-five or six."

Hao Dong took out his mobile phone and called Tian Chunda. Tian Chunda, who was also searching nearby, immediately rushed over. Hao Dong explained the situation to Tian Chunda.

Tian Chunda took out the matchbox found near the scene for the old man to identify. The old man pointed to a chrysanthemum on the matchbox and said, "When painting the doors and windows of my house, Luo Jian used this kind of match to light a cigarette and smoke, and I also warned him: "Be careful of fires when smoking." ”

The clues all point to Luo Jian, but more evidence is still needed to arrest Luo Jian or search Luo Jian's home. According to the Code of Criminal Procedure, if it is not an emergency, the police must first apply for a search warrant or arrest warrant from a superior if they want to search a house or enter a house to arrest a suspect. The police must attach an application to the application, and there are sufficient grounds to believe that there is evidence of the case in the house or that the arrested person may be involved in the case.

However, the police still do not have sufficient evidence. Tian Chunda proposed a method to test Luo Jian with the single-edged knife he found.

Tian Chunda and Hao Dong came to Luo Jian's house. I went up and knocked on the door, but for a long time, no one answered the door. After a few more minutes, I saw a woman about fifty years old, with a lot of wrinkles on her face, lift the corner of the curtain and open a thin slit to look at the knocker outside.

"We're police officers and want to ask about something." Tian Chunda took out his ID and showed it to the woman.

"What's the matter?" The woman asked nervously.

Tian Chunda didn't want to startle the snake, so he said: "I want to inquire about the situation." ”

The woman opened the door, and Tian Chunda asked, "You are Luo Jian's mother, right?" ”

The woman nodded.

"Is Luo Jian at home?" Tian Chunda asked again.

The woman became more nervous and hurriedly asked, "What happened?" What trouble did Luo Jian cause? ”

"It's nothing, we just want to ask him about a knife." Tian Chunda replied.

"He's not at home." She replied.

Tian Chunda took the photo of the knife to her and asked, "Have you ever seen this knife?" ”

She took the photo and looked at it, frowned and thought for a while, shook her head and said in a hesitant voice, "No, no." ”

Tian Chunda asked again with a tentative mentality: "Can you let us go into the house and have a look?" ”

She immediately became alert and asked, "What are you looking for?" I've told you I haven't seen this knife unless you have a search warrant, or don't want to set foot in my house. ”

Luo Jian's mother was tight-lipped and it was difficult to enter the house to search, but her abnormal behavior made Tian Chunda even more suspicious.

Just as Tian Chunda and Hao Dong turned to leave, they didn't expect to meet a teenage girl running home outside the door.

Tian Chunda asked her with a smile: "Little girl, are you Luo Jian's sister?" ”

The little girl nodded, "Yes." ”

Tian Chunda took the photo and asked him: "Little girl, have you seen this knife?" ”

The little girl glanced at it and immediately replied, "Isn't this my eldest brother's knife?" This is a birthday present from my dad, an import. He treats this knife as a treasure and never lets anyone else touch it. ”

Tian Chunda immediately asked, "Do you know where this knife is now?" ”

The little girl replied, "He said he accidentally lost the knife the other day. How is this possible? Ever since my dad gave him this knife, he's always had it with him. Always take care of this knife, I don't believe he will lose it......"

"Don't talk nonsense, come in quickly!" Luo Jian's mother stood in front of the door and shouted loudly to stop the little girl, and the little girl had to wave her hand and run into the house.

Tian Chunda decided to wait for Luo Jian to come back and ask for clarification. He and Hao Dong were waiting by the courtyard gate.

Soon a young man in his twenties came to the front of the house, and when he saw the police outside, he immediately became nervous, but quickly pretended to be calm.

Tian Chunda stepped forward and asked him, "You are Luo Jian, right?" ”

The young man nodded.

"We're the police." Tian Chunda showed him his ID and asked, "Is the knife your father gave you on you?" ”

He replied, "I have left it in my house." ”

Tian Chunda said: "Then can you go into the house and find out?" ”

"Okay." Luo Jian promised to go into the house to find it.

At this time, Tian Chunda whispered to Hao Dong: "I think Luo Jian is very similar to the person who was photographed by the camera at He Zhi's house. ”

Hao Dong nodded: "It's quite similar." ”

It took Luo Jian more than half an hour to come out and said, "I couldn't find the knife after looking for a long time, maybe I accidentally lost it." ”

Tian Chunda wanted to find a place to interrogate Luo Jian carefully, about the knife, about the situation under the camera. He said to Luo Jian: "Let's find a place to talk, okay?" ”

At this time, Luo Jian's mother said: "Luo Jian still has work to do outside after dinner. Go back first, and ask tomorrow if you have something. ”

Tian Chunda and Hao Dong couldn't take coercive measures against Luo Jian now, and they were afraid that if they insisted too much, they would startle the snake, so they had to say goodbye.

Walking in the returning police car, Hao Dong said to Tian Chunda: "Team leader, I think this Luo Jian is too suspicious, maybe Liu Ye and He Zhi were killed by him." ”

Tian Chunda said: "There may also be a person who was killed by him. ”

Hao Dong said: "Chu Wenguang. ”

Tian Chunda nodded. He said again: "This Luo Jian is too suspicious, the stakes are very high, I will immediately ask my superiors now, and I will have to send someone to spy on him secretly tonight." He took out his mobile phone to call his superiors, reported the situation, and talked about his views. The superiors agreed with him and said that they would immediately send someone to monitor Luo Jian's home and spy on Luo Jian.

The two criminal policemen soon came to Luo Jian's house and secretly ambushed and monitored.
