Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

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.

"Lijun, how do you think this murderer left?"

How to 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, could come to the deceased's house in the middle of the night...

Motive for murder...

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.

Moreover, she is very beautiful and has many people chasing her.

From love to hate?

This case made Lu Chuan's head hurt.

I always feel clueless.

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.

Opening the cabinet, 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 a radio and television company.

Many people now use this kind of set-top box at home.

Because of convenience.

In the past, when watching TV, you needed a set-top box, which needed to be pulled and connected.

The network also requires cables, routers, and cats to connect.

There are a bunch of boxes and threads everywhere.

It's much better to use this kind of set-top box.

The network signal and the TV signal are all together, and compared to fiber optic, the network speed is about the same.

Of course, Lu Chuan was 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."

After half an hour.

"Lu Jun...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 at this glance, there is a real 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 use the Internet?
"Who are the neighbors on the left and right at home?"

If you can connect to WiFi, the distance is definitely not far.

And the connection through the wall can only be to neighbors across the door, upstairs and downstairs.

It's 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. "I'm coming."

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 am doing decoration. I haven't had much work recently. I am resting at home. Do you want to know more about the situation?"

Lu Chuan nodded: "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: "That's not true. I decorated Xiao Qin's house."

"It's a pity...hey..."

Dong Jun sighed.

"Team Lu, please have some 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?"

"It's not that I'm very familiar with it. I just bought this house not long ago. I was renovating the house across the door when I bought it, and then I also had to renovate it."

"After just two visits, we got to know each other."

"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 seems to be very talkative. He can always say a few words whatever Lu Chuan asks.

"You live by yourself?"

"Divorced, no children, just myself."

Dong Jun did not shy away from his divorce.

Lu Chuan then asked some questions about what happened on the night of the incident, and Dong Jun answered 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 I wake up when there's any movement."

"Did you hear any noise from the other side later?"

Dong Jun shook his head: "No, she said that after watching TV, I didn't think much about it."

"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 the all-in-one TV and Internet access machine back to the victim's home, and move the TV back as well."

"it is good!"

Gao Wenxiang called a few people and moved everything back to the criminal police brigade.

Lu Chuan spent more than three hours studying the two things carefully.

Six pm.

meeting room.

"Team Lu, Zheng Gaoxue has been released temporarily."

After 24 hours, there is no direct evidence that he is the murderer, so he can only be released.

Of course, this is what Lu Chuan meant.

Lu Chuan nodded: "Chen Jiang, how is the investigation going for you 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 relationships are relatively complicated."

What Chen Jiang is reporting is the situation of Qin Weiwei's neighbor Dong Jun.

Lu Chuan came back from the scene again and arranged for Chen Jiang to conduct investigations in this area. (End of chapter)
