Han Bin searched the house, and the doors and windows were closed, and there were no signs of damage.

No fingerprints were found in the house.

Yes, not even the fingerprints of the deceased were found.

The suspect should have cleared the scene when he left.

Half an hour later, the medical examiner also completed the preliminary autopsy.

The deceased, Liu Ling was drunk

Age, 28 years old

The cause of death was mechanical asphyxiation

Time of death, between 8 p.m. and 11 p.m. on June 4

Physical symptoms, surname behavior occurred before death.

After figuring out the situation at the scene, Ding Xifeng gathered everyone together.

Ding Xifeng took two puffs of cigarette and snuffed out the remaining cigarette butts, "Everyone should know the situation at the scene, and you can tell me your opinion." ”

In addition to Ding Xifeng, Chen Lin held the highest position and said, "Judging from the autopsy results, the deceased is likely to have been strangled to death, and his surname had occurred before his death. The place of death was in the bath, which is basically similar to Zhu Weichao's modus operandi. ”

"And the suspect should have cleaned up the scene when he left, indicating that he had plenty of time to commit the crime, and he was very calm, and he was probably a repeat offender. ”

Ding Xifeng nodded and looked at Han Bin on the side, "What do you think?"

"Most of my views are the same as Captain Chen's, but the deceased only had a surname before his death, and there was no obvious trauma, indicating that the deceased may have been voluntary. ”

Ding Xifeng frowned, judging from the situation at the scene, it is very likely that Zhu Weichao committed the crime, but neither fingerprints nor the murderer's DNA were left at the scene, and there was nothing enough to determine the identity.

Another point is like what Han Bin said, there is a big difference between voluntary and involuntary, and in his experience, if it is involuntary, there will be organic damage in most cases.

If it is voluntary, it means that the murderer knew the deceased.

It is not clear whether Zhu Weichao knew the deceased Ding Xifeng before, but Zhu Weichao has been imprisoned for two years and is a fugitive again.

To put it mildly, even if the deceased is his wife, given his criminal record, he may not dare to have an intimate relationship with him.

For a while, Ding Xifeng was also a little difficult to judge, and he needed more clues and evidence.

Leaders call and ask, and they definitely don't want to hear an ambiguous answer.

Subsequently, Ding Xifeng began to arrange tasks.

"Captain Chen, you take someone to visit the surrounding people to see if anyone has seen any suspicious people during the time period of the crime. ”

"Again, you send someone to make a detailed transcript for the landlord. ”

"Han Bin, you send someone to check the surveillance to see if there are any suspicious people who have entered and exited this building. ”

"Check the deceased's correspondence records. ”

"Again, make a note of the deceased's mother. ”

"Yes. ”

Afterwards, the crowd began to split up.

......

After Ding Xifeng finished arranging the task, Han Bin divided the task in detail.

Wang Xiao and Jiang Yang were sent to check the surveillance, Lin Qin contacted the technical department to check the deceased's communication records, Bao Xing was responsible for contacting the deceased's mother, and Han Bin stayed with Ding Xifeng.

After Han Bin finished arranging the task, he made a phone call to Ma Jingbo and explained the situation.

And Ding Xifeng was not idle, basically kept calling, either he reported the situation, or someone reported the situation to him, and the mobile phone never stopped.

Twenty minutes later, there was a commotion outside, and a woman in her fifties barged in, a woman of medium size, somewhat thin, with short hair, carrying a black bag in her hand, and an anxious look on her face.

"What about my daughter. ”

"Where is my daughter, I want to see her!"

Bao Xing walked over and asked, "Are you Zhang Suyun?"

"It's me, you're Officer Bao. The short-haired woman grabbed Bao Xing, "Where is my daughter, I want to see ...... with my own eyes"

Bao Xing turned his head to look at Han Bin, "Team leader, she is the mother of the deceased, and she is here to identify the body." ”

Han Bin looked in the direction of the toilet, Liu Lingdrunk had already been put into a body bag, "Go ahead." ”

Han Bin, Ding Xifeng and others walked outside.

After a while, there was a cry in the room.

Everyone is used to this situation.

After twenty minutes, the crying gradually stopped, and Han Bin entered the house.

Zhang Suyun sat on the sofa and covered her face and wiped her tears.

Bao Xing handed the other party a pack of tissues, "Ms. Zhang, please mourn and change." ”

Zhang Suyun didn't reply, still bowing his head and choking.

"If it's convenient, we want to ask some questions about Liu Ling's drunkenness, which will help our police solve the case as soon as possible. Bao Xing said.

Bao Xing obviously didn't have Li Qin to comfort people, but his words worked, Zhang Suyun still raised his head slowly, "Ask." ”

Bao Xing turned on the law enforcement recorder to record, and Han Bin was responsible for interrogation.

"Ms. Zhang, how did you find out that Liu Ling was drunk and killed?"

"I don't know. Zhang Suyun shook his head and wiped his face with his hand, "This morning, Lingling's company called me and asked Lingling why she didn't go to work, and I didn't know the situation, so I called Lingling, but I couldn't get in touch." ”

"I live alone, and I have had a heart attack before, Lingling knows that I am not in good health, and never turns off the phone, she is very filial. She also said that when she got married in the future, she would take me to live with her and ask me to help her take care of the children......"

"I had a feeling that something might have happened to Lingling. But I live a little far away, so I quickly called the police and asked the police to come and check, but I didn't expect it to be ......"

"Comrade policeman, have you caught the murderer? Who killed my family? ”

Han Bin replied, "When we arrived at the scene, there was no one in the house. Now we are collecting clues and will do our best to track down the murderer, what do you know, you can also tell us. ”

Zhang Suyun sighed, "It's too sudden, I never thought that this kind of thing would happen to Lingling." ”

Han Bin continued to ask, "Ms. Zhang, do you know Zhu Weichao?"

"I don't know, what's wrong?"

"He's a wanted criminal, and his modus operandi is similar to your daughter's situation, so we'd like to find out if they have crossed paths before. ”

Zhang Suyun asked rhetorically, "What did you say about Zhu?"

"Zhu Weichao, he has been in prison before, and even if your daughter knew him, it should have been two years ago. Han Bin said.

Zhang Suyun recalled for a moment, shook his head and said, "I don't remember, I haven't heard her say it." ”

"How many keys does Liu Ling's drunken family have?"

"I don't know. ”

"Do you have the key?"

"Nope. ”

"Has your daughter been doing anything unusual lately?"

Zhang Suyun recalled, "Yes, more than a month ago, she was beaten once, and her face was swollen for several days, but it hurt me. ”

"Who hit her?"

At first, she refused to say, but after I asked for a long time, she told me that it was a colleague of the company surnamed Feng who had an argument with her because of the customer, and the two of them started fighting. ”

Han Bin recorded, "What's your name?"

I asked, but she wouldn't say. I wanted to go to their company to ask for an explanation, but she stopped me from going for fear that it would affect her work. Zhang Suyun sighed and said helplessly,

"Comrade policeman, will my daughter's death be related to this incident?"

"It's hard to say right now, and further investigation is needed. ”

"If I had known, I should have gone to their company, maybe what happened today wouldn't have happened. Zhang Suyun said regretfully.

"Don't blame yourself, it's been a month, and it doesn't have to be related to what happened before. Bao Xing comforted.

Han Bin flipped through some notebooks and continued to ask, "Ms. Zhang, does Liu Lingdrunk have a boyfriend?"

"Yes. ”

"What's her boyfriend's name?"

"I want to think about it...... It seems to be called Lin Jianrong, yes it is Lin Jianrong, I met me last year, the two have been together for three years, the relationship has always been very good, listen to my daughter, there are plans to marry him. ”

"Do you have his contact information?"

"I didn't. ”

Han Bin marked it on the notebook, there was not a single photo of a man in the room, nor a man's slippers, toothbrushes, or gifts.
