The door to the crime scene was unlocked and a cordon was set up outside.
Everything in the room is still the same as it was after Qin Weiwei was killed.
Generally speaking, houses where murders have occurred are not easy to sell.
And the betrayal will only be possible after the case is solved.
Qin Weiwei’s parents came to Haizhou City last night, and Sun Biao was handling the matter.
They are not allowed into the house just yet.
"Li Jun, how do you think the murderer left?"
How did he leave?
Standing next to the sofa, Lu Chuan carefully observed every place in the room.
He is also strange.
How did the murderer leave?
An acquaintance, a male, can come to the deceased's house in the middle of the night...
The motive of killing...
Why kill?
Judging from the current survey results, Qin Weiwei's popularity in the advertising company is pretty good.
According to her colleagues, Qin Weiwei has never had a conflict with anyone in the company.
And she is very beautiful, and there are many people chasing her.
From love to hate?
This case made Lu Chuan’s head hurt.
I always feel like I have no clue.
Turning around, Lu Chuan was about to leave when his eyes suddenly froze.
Qin Weiwei’s house had just been purchased not long ago, and all the rooms had been renovated.
The TV is wall-mounted, with a suspended TV cabinet underneath.
Lu Chuan's attention was attracted by a flashing blue light inside the TV cabinet.
Open the cabinet, and the flashing light is the TV set-top box.
Lu Chuan knew that this kind of set-top box had TV signals and Internet signals together.
It is an all-in-one Internet TV machine launched by the Radio and Television Company.
Many people now use this kind of set-top box in their homes.
Because of convenience.
In the past, when watching TV, I needed a set-top box, which required pulling wires and then connecting.
The network also requires cables, routers, and cats to connect.
One lane, a pile of boxes, and threads everywhere.
It will be much better if you use this set-top box.
Internet signals and TV signals are all together, and compared with optical fiber, the Internet speed is about the same.
Of course Lu Chuan is not concerned about the set-top box itself.
It's what's inside.
"Lao Gao, go back to the team and get me a laptop."
Half an hour later.
"Lijun...you can do this?"
Gao Wenxiang was stunned when he looked at the string of codes flowing on the computer screen.
Is this a hacker?
Lu Chuan shook his head: "With a little trick and a program, you can do it."
Gao Wenxiang said that he should...not be able to do it.
What Lu Chuan has to do now is very simple, which is to export all the mobile devices connected to this set-top box.
Since the murderer and Qin Weiwei may be acquaintances, will he connect to Qin Weiwei's WiFi when he comes to her home?
Of course, this is only possible.
Lu Chuan just took a look.
But with this look, we really have a clue.
Because right now, there are mobile devices connected to Qin Weiwei’s home WiFi.
Everyone is dead, and there are still people here to surf the Internet?
"Who are the neighbors on the left and right at home?"
If you can connect to WiFi, it must not be far away.
And the connection through the wall can only be to neighbors across the door, upstairs and downstairs.
Unlikely to be someone further away.
Gao Wenxiang didn't know who was there.
Lu Chuan put down his computer and went out directly.
Dong dong.
Lu Chuan directly knocked on the door opposite. "Come on, come on."
Dong Jun opened the door, saw Lu Chuan, and recognized him.
"Hello, officer, is there anything else you can do?"
Lu Chuan looked at the other person and focused on his mobile phone.
"Not at work?"
Dong Jun shook his head: "I'm doing decoration. I haven't had much work recently. I'm resting at home. Do you want to know more about the situation?"
Lu Chuan Nodding: "Yes, there are some details about what happened that night. I still want to know more about it with you."
"No problem, please come in."
Dong Jun's house has the same layout as Qin Weiwei's house opposite.
And it seems to have been recently renovated, making it clean and bright.
"Mr. Dong, it seems to me that the house opposite has just been renovated not long ago, and the style is very similar to yours."
Dong Jun poured water for Lu Chuan and Gao Wenxiang: "Then But no, I decorated Xiao Qin’s house.”
"What a pity...ah..."
Dong Jun sighed.
"Team Lu, please have tea."
After Gao Wenxiang introduced him just now, Dong Jun knew that this was the captain of the criminal police brigade.
“Are you familiar with Qin Weiwei?”
"I can't say that I'm very familiar with him. I just bought this house not long ago. I bought a house across the door while I was renovating it, and then I also had to renovate it."
"After going back and forth, I got to know each other."< br>
“The decoration I did for her was at a low price. They are all neighbors anyway, and I didn’t expect to make much money. It’s just a pity that she is so young...”
Dong Jun seemed very happy. Talkative, he could always say a few words about anything Lu Chuan asked.
“You live alone?”
"If you are divorced and have no children, you are on your own."
Dong Jun is not shy about his divorce.
Lu Chuan then asked some questions about what happened on the night of the incident, and Dong Jun answered very cooperatively.
"Hey, it's all my fault. If I had thought more carefully that night, Xiao Qin might have been fine..."
Dong Jun looked annoyed and seemed to really blame himself.
"Mr. Dong, according to what you said, it was around three o'clock in the morning. Why are you still up so late?"
"Oh, I've actually fallen asleep, but I'm a light sleeper and wake up when there's the slightest movement. "
"Did you hear any sound from the other side?"
Dong Jun shook his head: "No, I didn't think much about it after she said it on TV."
“Maybe the sound on her TV is too loud.”
television?
Lu Chuan frowned slightly. Who the hell is watching TV at three o'clock in the middle of the night? It's a ghost movie.
Qin Weiwei cannot have excessive mood swings due to physical reasons.
Watching ghost movies in the middle of the night, do you think your life will be long?
The questioning of Dong Jun did not last long.
Lu Chuan went to the neighbors upstairs and downstairs successively.
The neighbor upstairs is an old man in his seventies, and the person downstairs is away from home at work.
"Take back the integrated TV and Internet access machine at the victim's home, and move the TV back as well."
"Okay!"
Gao Wenxiang called a few people, Moved everything back to the criminal police brigade.
Lu Chuan spent more than three hours studying the two things carefully.
Six o'clock in the afternoon.
Conference room.
"Team Lu, Zheng Gaoxue has been released for the time being."
The 24 hours are up, and there is no direct evidence to prove that he is the murderer, so we can only release him.
Of course, this is what Lu Chuan meant.
Lu Chuan nodded: "Chen Jiang, how did the investigation go with the things I asked you to do this afternoon?"
Chen Jiang asked his men to turn on the projector: "We already have some clues."
"Dong Jun, 38 years old, divorced, engaged in decoration engineering, is the owner of a small decoration company."
"He is from Haizhou City. He came from Tianzhou City 10 years ago to work hard. Social interpersonal relationships are more complex.”
What Chen Jiang is reporting on is the situation of Dong Jun, Qin Weiwei's neighbor.
Lu Chuan came back from the scene again and arranged for Chen Jiang to conduct an investigation in this area. (End of this chapter)
