The victim of Zhu's super bath murder was named Lin Qiuyun, who was 34 years old at the time of his death and worked for a food company.

Family members include parents, husbands, daughters, and younger sisters.

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

The direction of the investigation back then was mainly based on surveillance, and Zhu Weichao wore a hat when he committed the crime, and he lowered his head wherever there was a camera, which can be regarded as being more careful.

However, the police checked a large number of surveillances and still saw some of his characteristics, such as his body shape, the color of his hat, the gray backpack, and the time of the crime.

From the monitoring of the victim's community, to the monitoring of street shops, and Skynet monitoring, little by little investigation, several major suspects were finally locked, and Zhu Weichao was one of them.

The murderer left DNA at the crime scene, which was completely consistent with Zhu Weichao's DNA after comparison.

After Zhu Weichao was arrested, he refused to confess at first, and after several days of interrogation before confessing, he admitted that Lin Qiuyun killed himself, and recounted the process of killing, which was completely consistent with the evidence found by the police.

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

At that time, the case was characterized as a burglary and murder case, and it was not considered to be a hired killing.

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

If it was a simple burglary and strong homicide case, the previous investigation method was not wrong.

This kind of case is relatively random, and many of them are wandering crimes, and the investigation is generally based on evidence.

Homicide for hire is different, as it is a targeted homicide.

To put it bluntly, it is an acquaintance who commits a crime.

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

The direction of investigation is mainly based on the surrounding relationships of the victims.

Because strangers have no grievances and no hatred, it is impossible to spend money to hire and kill, and even if Lin Qiuyun dies, it will not be good for the mercenary.

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 learn some information from him.

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

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

After a while, the mobile phone was connected, and Han Bin got straight to the point, "Hello, is it Mr. Cheng Jiwen?"

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

"I'm Han Bin from the Qindao City Criminal Investigation Brigade, and I want to know something about it. ”

There was silence on the other end of the phone for a moment, "You're a police officer?"

"Yes, I'm from the Municipal Public Security Bureau. ”

There was a little doubt in the man's tone, "What do you want me to know, I have nothing to do with your police." ”

"We would like to learn from you about Lin Qiuyun's case. ”

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

Han Bin explained, "Regarding this case, we have discovered some new information, and the murderer is likely to have accomplices. We are now re-investigating the case, and we also hope to catch the murderer. ”

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

"I'd love to have you in person if it's convenient. Han Bin said.

There was silence on the other end of the phone for a moment, "Are you really a police officer?"

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

Cheng Jiwen asked, "How can there be a murderer, didn't the case have been closed back then?" ”

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

"Okay, then I'll go and call this number 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 and I'll get there as soon as possible. After Cheng Jiwen finished speaking, he hung up the phone.

Han Bin also put away his mobile phone and said to the other team members, "Luckily, Cheng Jiwen hasn't changed his mobile phone number yet." ”

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

"I'll leave it to you. 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 his office.

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

"Excuse me, which one is Officer Han?"

Han Bin heard the other party's voice, got up and said, "I'm Han Bin, you are Mr. Cheng Jiwen." ”

The man nodded, "It's me." ”

"You may be seated. Han Bin made a gesture of please.

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

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

Cheng Jiwen bit his lip, "As soon as I arrived at the Public Security Bureau, I had some indescribable feelings in my heart, which made me can't help but think of my wife, this feeling...... Not so good. ”

Han Bin subconsciously asked, "Have you remarried?"

Cheng Jiwen shook his head and said, "No, remarried families are more tired, it's not as easy as being alone, and my wife's tragic death makes me don't want to start a family anymore." ”

"How is your relationship with Lin Qiuyun?"

"Very good, I love my wife very much, I was going to live with her for the rest of my life, I really didn't expect ......it," Cheng Jiwen showed a touch of sadness, "It's that I didn't take care of her." ”

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

"It was a weekend, I took my daughter back to my hometown to see my parents, I ......" Cheng Jiwen said this, suddenly paused, looked at Han Bin and said, "Officer Han, why did you suddenly ask about this, you don't suspect me." ”

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

Cheng Jiwen said, "After the case was discovered, the police had already made a record for me, and it should be in the file." ”

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

Cheng Jiwen sighed, "What is the new situation, can you tell me, the police have clearly told me that the case is closed, and now they say that there are new clues, as the victim's family, I really can't accept it." “

Han Bin hesitated for a moment, but decided to tell the other party about the matter.

First, he can understand Cheng Jiwen's current feelings, he must be confused when he suddenly receives this call, and the case back then is not a good memory for him, and anyone will have some resistance in their hearts.

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

Han Bin asked, "Do you know about Zhu Wei's escape from prison?"

Cheng Jiwen was red-eyed and complained, "You should have killed him a long time ago, why didn't this kind of demon be shot and kept, now that he has escaped from prison, your police are looking for him all over the world, I don't even know ......"

Han Bin said, "Zhu Weichao is dead. ”

Cheng Jiwen was stunned 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 should have died a long time ago, how did he die, was he shot dead by your police." ”

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

Cheng Jiwen gritted his teeth and said, "If you bury it well, this kind of person should be buried alive, so that he will slowly die of despair." ”

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

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

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

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

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

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

Cheng Jiwen continued, "You came to me, you didn't want me to help catch the murderer who killed Zhu Weichao." ”

Han Bin didn't hide it, "Yes, we are indeed tracking down the murderer who killed Zhu Weichao at present." ”

Cheng Jiwen stood up and said in a cold voice, "If that's the case, I have nothing to say!"

Han Bin persuaded, "Mr. Cheng, don't worry, listen to what I say." ”

Cheng Jiwen showed a hint of mockery, "In my opinion, there is nothing more to say." ”

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

"Thank you. ”
