The victim of Zhu Weichao's bathing murder case was Lin Qiuyun, who was 34 when he died and worked for a food company.

Family members include parents, husband, daughter, and sister.

Han Bin carefully checked the file of the bath murder case.

The direction of investigation back then was mainly surveillance. Zhu Weichao wore a hat when committing a crime, and kept his head down wherever there was a camera, he was more careful.

However, the police checked a lot of surveillance, and still saw some of his characteristics, such as his size, the color of the hat, the gray backpack, and the time he committed the crime.

From the monitoring of the victim’s community, to the monitoring of street shops, and the Skynet monitoring, bit by bit investigations led to several major suspects, and Zhu Weichao was one of them.

The murderer left his DNA at the crime scene, and after comparison, the DNA of Zhu Weichao completely matched.

After Zhu Weichao was arrested, he refused to confess at first. He confessed after several days of interrogation. He admitted that Lin Qiuyun killed himself, and described the killing process, which was in full agreement with the evidence found by the police.

However, Zhu Weichao did not confess his accomplices from beginning to end.

The case that year was classified as a robbery and robust homicide case, and no consideration was given to hiring a homicide.

The nature of these two homicides is different, and the direction of investigation is also somewhat different.

If it is a simple robbery and robust murder case, the previous investigation method is not wrong.

The randomness of this kind of cases is relatively strong, and many of them are flurry of crimes, and investigations are generally initiated from the aspect of evidence.

The hire homicide case is different, which is a targeted homicide.

To put it plainly, acquaintances commit crimes.

There must be a certain entanglement between each other, love, hatred, or interest.

The investigation direction is mainly based on the victim's peripheral relationship.

Because strangers have no grievances and no grudges, it is impossible to spend money to hire people to kill. Even if Lin Qiuyun died, it would be no good to the employer.

Lin Qiuyun's daughter is not yet an adult and is temporarily excluded.

After thinking about it, Han Bin decided to contact Lin Qiuyun's husband first to get some information from him.

Lin Qiuyun's husband is Cheng Jiwen, and his contact information is in the file.

However, more than two years have passed since the incident, and no one can guarantee whether he changed his contact information.

After a while, the phone was connected, and Han Bin said straightforwardly, "Hello, is this Mr. Cheng Jiwen?"

A man's voice came from the phone: "It's me, who are you?"

"I'm Han Bin from the Criminal Investigation Brigade of Qindao City. I want to know something with you."

There was a moment of silence on the other end of the phone, "Are you a policeman?"

"Yes, I am from the Municipal Public Security Bureau."

The man's tone was a little confused, "You ask me to find out what is going on, I have nothing to do with your police."

"We want to know about Lin Qiuyun's case with you."

The other end of the phone was silent for a while, "Isn't my lover's case solved, what else is there to understand."

Han Bin explained, “About this case, we have discovered some new information. The murderer is likely to have an accomplice. We are now investigating the case again, hoping to kill the murderer.”

"What accomplice? Isn't there only one murderer in that case?"

"If it's convenient, I hope I can talk with you face to face." Han Bin said.

There was a moment of silence on the other side of the phone, "Are you really a policeman?"

"If you don't believe me, you can come directly to the Second Squadron of the City Criminal Investigation Brigade to find me. My name is Han Bin."

Cheng Jiwen asked, "How could there be another murderer? Wasn't the case closed back then."

"Some words are inconvenient to speak on the phone, and it is easier to speak clearly in person." Han Bin said.

"Okay, then I'll go, do I make this call when I get to the Municipal Public Security Bureau?"

"Yes, where are you now and when will you be able to come over?"

"I'm not far away, I will rush over as soon as possible." Cheng Jiwen finished speaking and hung up the phone.

Han Bin also put away his mobile phone and said to the other team members, "Good luck, Cheng Jiwen has not changed his mobile phone number."

Li Qin asked, "Group leader, do you want to contact Lin Qiuyun's parents?"

"Leave it to you to contact." Han Bin said.

Sometimes it can be difficult to communicate with older people, and Han Bin doesn't want to spend too much energy on this matter.

Forty minutes later, Cheng Jiwen rushed to the Municipal Public Security Bureau, and Han Bin told him the location of the office.

A few minutes later, a man in his thirties knocked on the door and walked in. The man was wearing glasses, a striped T-blood, and a pair of dark pants.

"Excuse me, who is Officer Han?"

Han Bin heard the other party's voice and stood up and said, "This is Han Bin, you are Mr. Cheng Jiwen."

The man nodded, "It's me."

"Please sit down." Han Bin made a please gesture.

Cheng Jiwen looked a little cautious, looked at the office environment, and then sat on a chair with his hands twisted together.

Han Bin felt that the other party was a little nervous and said, "Mr. Cheng, you don't need to be nervous, we are just looking for you to find out some information."

Cheng Jiwen bit his lip. "As soon as I arrived at the Public Security Bureau, I felt a little unspeakable. It would make me think of my wife. This feeling...not very good."

Han Bin asked subconsciously, "Are you remarried?"

Cheng Jiwen shook his head and said, "No, remarrying family is more tiring, not as easy as being alone, and the tragic death of my wife made me no longer want to start a family."

"How is your relationship with Lin Qiuyun?"

"Very well, I love my wife very much. I planned to live with her for the rest of my life. I really didn't expect it..." Cheng Jiwen showed a sad look, "I didn't take care of her."

"Where were you when Lin Qiuyun was killed?" Han Bin asked.

"It was a weekend, and I took my daughter back to my hometown to see my parents, I..." Cheng Jiwen said this, and suddenly paused, looking at Han Bin and said, "Officer Han, why did you suddenly ask about this? , You don’t doubt me."

Han Bin explained, "No, don't get me wrong, I just want to learn more about Lin Qiuyun's case."

Cheng Jiwen said, "After the incident happened that year, the police had already made a transcript for me, which should be in the file."

"I said on the phone before that we found some new clues, so we need to understand the situation of the case from different directions." Han Bin said.

Cheng Jiwen sighed, "Can you tell me what is the new situation? The police had clearly told me that the case was over. Now they said that there are new clues. As the victim's family, I really accept it. No more."

Han Bin hesitated, but decided to talk about the matter with the other party.

One is that he can understand Cheng Jiwen's current feelings. It must be daunting to receive this call suddenly, and the case of the year is not a good memory for him, and anyone will feel a little bit of resistance.

Another trust and communication are mutual. If Han Bin wants to learn more from the other party, he must inform the other party accordingly.

Han Bin asked, "Do you know that Zhu is beyond prison?"

Cheng Jiwen looked red and complained, "You should have killed him a long time ago. Why don't you keep this kind of demon shot? Now you have escaped from prison. Your police are searching all over the world. I don't know..."

Han Bin said, "Zhu Weichao is dead."

Cheng Jiwen was taken aback for a moment and repeated, "Dead? You mean the murderer who killed my wife is dead."

"Yes."

Cheng Jiwen smiled, "Deserve it, retribution, this kind of person deserves to die a long time ago, how did he die, was it shot by your police?"

"When our police found him, he was dead. He was buried alive." Han Bin said.

Cheng Jiwen gritted his teeth and said, "If buried well, this kind of person should be buried alive, let him slowly die of despair."

"Which hero killed him, I want to thank him, and our whole family must thank him!"

Han Bin frowned slightly, "We are also tracking down the murderer who killed Zhu Weichao."

"Murder?" Cheng Jiwen shook his head, revealing a strange look, "No, he is a hero! I hope you can't find him, you will never find him."

"I can understand how you feel. But he also killed people and broke the law." Han Bin said.

Cheng Jiwen disdainfully said, "So what, I only know that he avenged my wife, and I want to thank him for helping the people."

Han Bin was a little embarrassed, he could hear the dissatisfaction in Cheng Jiwen's words.

Cheng Jiwen continued, "You are looking for me, don't you want me to help catch the murderer who killed Zhu Weichao?"

Han Bin did not hide, "Yes, we are indeed looking for the murderer who killed Zhu Weichao."

Cheng Jiwen stood up and said coldly, "If this is the case, I have no comment!"

Han Bin persuaded, "Mr. Cheng, don't worry, listen to me to finish."

Cheng Jiwen showed a touch of sarcasm, "In my opinion, there is nothing left to say."

Cheng Jiwen turned around and walked outside, then stopped, and said, "Officer Han, I still want to thank you for telling me the good news!

"Thank you."
