"Judging by time, when sending this WeChat, Xue Mengjiao should have been controlled by the murderer, and had not been killed by the murderer. Could it be that she sent it under the threat of the murderer?" Du Qi said.

Han Bin pondered for a moment: "I don't think it's possible. If it was really threatened by a murderer, she would probably say that she would not go home tonight and stay at a classmate or friend's house for one night. If she doesn't understand the situation of Xue Mengjiao's house, The murderer may not doubt, why should Xue Mengjiao lie such a perfect lie under the coercion that Lin Yuejiao didn't have the slightest doubt."

"If it is really an acquaintance who committed the crime, I think Xia Binhai's suspicion has risen further." Tian Li said.

"In this way, I will arrange the task in advance." Han Bin organized the language and continued:

"Once Xue Mengjiao's DNA comparison and identification is successful; Du Qi is applying to investigate her communication records."

"Tian Li, you are responsible for finding the whereabouts of Xia Binhai."

"I took people to visit the Shimian community to see if there were any witnesses."

"Yes."

Although all the clues pointed to Xue Mengjiao as the deceased, the appearance of the deceased was damaged. To apply for some investigation procedures, it still needs to be based on the DNA identification certificate.

It was already eight o'clock in the evening when Han Bin got home, and his mother left him a meal.

After dinner, I sat in the massage chair and chatted with my grandpa for a while, and then went back to sleep upstairs.

Generally, when there are important cases in hand, Han Bin will ensure his sleep, if he finds important clues, let alone sleep, he will not care about eating.

...

Early the next morning.

Yuhua branch, technical team.

After going to work, Han Bin did not go back to the office, and went directly to the technical team.

The technical team is on the fourth floor, and there is a smell of potion floating in the corridor.

Next to the stairs is the office of the technical team. As for the laboratory, Han Bin could not enter.

There was only one female police officer on duty in the technical team. After asking Han Bin's intentions, she asked Han Bin to wait in the office and she went to the laboratory to inquire.

Han Bin didn't worry, and just sat in a chair and waited.

He didn't come to the technical team very often. To be honest, he never entered the laboratory. He was also a little curious about what it would look like inside.

A few minutes later, the door of the office opened, and Ruben walked into the office: "Rare, it's the first time Team Leader Han has come to me."

"I have been here three or four times, but you are not there." Han Bin shrugged.

"Group leader Han, you are very concerned about this case."

"It's not okay if you don't care, this is a serial homicide. After the first deceased was killed, even the city criminal investigation team did not catch the murderer. I am under a lot of pressure. Can I not hurry up?" Han Bin showed a bit of bitterness.

"That's true, the suspect in this case is also a ruthless character." Lu Wen said.

"How about, have the identification results of the deceased come out?"

Ruben handed over a document: "Without this, I would not dare to see you."

Han Bin smiled and accepted the authentication certificate.

Lu Wen gave a brief introduction: "The DNA comparison between Lin Yuejiao and the deceased is indeed a mother-daughter relationship."

"Well, I feel at ease with this." Han Bin said.

Saying one thousand words and ten thousand words, inference is after all inference.

"By the way, have the fingerprints on the avoidance set been matched?"

"It's still being compared in the database."

"Thanks." Han Bin reached out and patted Ruben on the shoulder.

No matter how strong Han Bin's criminal investigation ability is, he can't do without the support of the technical team if he wants to solve the case.

Han Bin was anxious to investigate the case and did not stay in the technical team. He greeted Ruben and left.

With this identification certificate, it can be determined that Xue Mengjiao is the deceased, and there is a basis for speculation about the case.

According to Han Bin's task arrangement yesterday, the second group began to investigate separately.

...

Shimian district is an old district.

The Shimian community is divided into three phases, namely the first asbestos community, the second asbestos community, and the third asbestos community.

These three communities are connected together, and it is difficult for outsiders to distinguish clearly except for the old residents of the community.

Han Bin, Li Hui, and Zhao Ming drove to the Shimian community.

At the beginning, the three of them were going to drive around the neighborhood, but the car stopped halfway through the drive. Because the road in the neighborhood was narrow and random parking was serious, especially when meeting cars, it was troublesome. Stop by the side and let the car on the opposite side drive past, so that you can drive forward.

Later, the three of them simply got out of the car and strolled around the community, one to check the surroundings of the community, and the other to check the location of the camera.

After making a round in the community, Han Bin found that the community was monitored, but most of them were unusable.

In a cold day, there was not even a person resting outside. Han Bin and others wanted to inquire, but they couldn't find anyone.

Afterwards, Han Bin and the three simply went to the neighborhood committees nearby, which are generally responsible for such old communities.

After arriving at the neighborhood committee, the reception for Han Bin and others was an aunt in her fifties. Although she was not young, she was very fashionable. She had short black hair and an Apple mobile phone in her hand. She was quite capable.

"A few comrades, sit down, what's the matter with us in this cold weather?" the aunt asked.

"Aunty, what do you call?"

"My name is Lin."

Han Bin took out the police officer's card and let Aunt Lin take a look: "We are from the Criminal Investigation Team of the Yuhua Branch. We are investigating a case. A suspected vehicle has been to the Shimian community. We want to know the situation.

"The Shimian community is divided into three phases, is it the first phase and the second phase, or the third phase?"

"I can't tell you this. We came to see you just to check the monitoring."

"There is monitoring, but it's not ours, it's the property company."

"Which property company?"

"Wangcai Property Company."

"Auntie, I heard that right, the property company is called Wangcai?" Zhao Ming asked in surprise.

Aunt Lin smiled: "I know what you are thinking, but this property company is called Wangcai, and it can't be faked."

"Where is this property company, can you give us a contact or address?" Han Bin asked.

"I can't remember where it is. I'll check your phone number for you." Aunt Lin took out a small book and started looking through it. After a while, she said, "Please remember, 134254xxxx"

Han Bin was about to call, but Aunt Lin stopped him: "I'll call it. People from the property management company recognize me, and communication is easy."

"Thank you." Han Bin was naturally happy to save time for investigation.

Aunt Lin walked to the side, contacted Wangcai Property Management Company, and then said to Han Bin on the side: "Yes, I'll take you there. The land is not easy to find."

"Okay, I'll trouble you." Han Bin smiled, this aunt is very enthusiastic, quite suitable for working in the neighborhood committee.

A group of four people got in the car and went to Wangcai Property Company under the guidance of Aunt Lin. The distance was not far, it only drove for ten minutes.

Wangcai Property Management Company is in an alley with an old sign hanging at the door. There is only one door-faced room with a few computers. There are several people sitting and chatting in the room.

The person in charge of Wangcai Property Management Company is a manager surnamed Chen. He is a man about 40 years old. He is very enthusiastic after meeting Aunt Lin.

After Han Bin and others explained their intentions, Manager Chen looked embarrassed: "Comrade police, if you want to watch surveillance, it must be fine, but..."

"what's happenin?"

“Most of the monitoring is no longer available. There are only five monitorings available now. There are two monitorings in the first phase and second phase of the Shimian community, and one monitoring in the third phase." Manager Chen said.

Li Hui questioned: "Your property company is too irresponsible. We went to the Shimian community for a while. There was not much monitoring and most of them were not available. Can this ensure the safety of residents?"

"Comrade police, there is nothing we can do. The key is that there is a tight budget and nothing can be done." Manager Chen said helplessly.

"Isn't there a property fee? Where did the property fee go?"

Manager Chen sighed: "I'm not afraid of your jokes. I can't collect tens of thousands of property fees this year. I will also be responsible for cleaning up the **** in the asbestos community, collecting water and electricity bills, and repairing the pipeline if it is broken. We can't make two dollars. If it weren't for Aunt Lin's face, we wouldn't want to do it."

"How much does your property cost?" Zhao Ming asked.

"We charge by household. The Shimian community has three apartment types, one for one hundred, two for one hundred and five, and three for two hundred."

"One month?"

Manager Chen shook his head: "One year."

Zhao Ming calculated it: "There are two to three thousand households in this Shimian community, so it stands to reason that it can collect hundreds of thousands of property fees."

"Comrade, let me tell you the truth. It would be nice to have one tenth of the people paying the property fee, but it really can't be collected." Manager Chen complained.

"There are a few monitors, count a few. Manager Chen, please help us copy it." Han Bin didn't want to entangle this matter.

"Tingling bell..." At this moment, Han Bin's cell phone rang, and he took out his cell phone and took a look. The screen showed Ducci's number.

Han Bin left the property management company and pressed the answer button: "Hey."

"Group leader, Xiaopeng and I are in a communications company. We have checked Xue Mengjiao's communication records and printed out a list of recent contacts." Du Qi's voice came from the mobile phone.

"Have you found any suspicious contacts?"

"The day before yesterday at about four o'clock in the afternoon, Xue Mengjiao contacted a person named Yao Chuang, who was also Xue Mengjiao's last contact. I checked his registration information and lived in the Shimian community." Du Qi said. I added another sentence:

"This Yao Chuang talks with Xue Mengjiao very frequently. The two people should be familiar with each other. I guess that Xue Mengjiao came to Shimian Community and it is very likely that he came to see Yao Chuang."

"We are now near the Shimian community, you send over the details of Yao Chuang, and we will investigate."

"Yes."

After copying the video, Yao Chuang's information was also sent over.

Han Bin and others immediately returned to the Shimian community.

Yao Chuang is the last person to contact Xue Mengjiao and lives in the Shimian community. He is most likely the person involved...
