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

Chapter 758 Clues
On the projection is personal information about Dong Jun.

Lu Chuan read it very carefully, studying every piece of information over and over again.

Judging from Dong Jun's background investigation, there is not much contact between him and Qin Weiwei.

I opened a small decoration company to undertake some decoration work for individual homes.

Although I can't make much money, my life is pretty good.

"Dong Jun is a very loyal person, and those who work with him think highly of him."

Chen Jiang continued to introduce the investigation situation.

"His company has no other permanent staff except him. When he is contracted for decoration work, he organizes a temporary team."

"So when nothing happens, he stays at home."

"Army, this is the basic situation."

Every on-site inspection is actually equivalent to turning the entire site upside down.

"So is it possible that this acquaintance has connected to Qin Weiwei's home WiFi signal?"

"I found something interesting, let's take a look..."

But there is always something missing.

"This afternoon, when I was at the scene, I cracked the data signal in the set-top box and made a detailed analysis."

What is shown on the projected photo is the set-top box in Qin Weiwei's home.

"Judging from the preliminary investigation results, the person who killed Qin Weiwei should be someone she was familiar with."

This is also considered a routine operation.

Lu Chuan asked Gao Wenxiang to project what he discovered just this afternoon on the screen.

"Something was found at the site, something very interesting."

Lu Chuan nodded. There wasn't much information, but it had some reference value.

Just like the first time Lu Chuan went to the site to investigate, he found something different from the second time he went to the site.

The video shows a series of mobile device information connected to Qin Weiwei’s home set-top box.

"Lu Lie, do you suspect that Dong Jun... has a problem?"

Sometimes handling a case requires not only inspiration, but also luck.

Lu Chuan operated the projection to display the next photo.

Wang Zhaokai knew that there must be a reason why Lu Chuan suddenly investigated Dong Jun.

"This afternoon Gao Wenxiang and I went to the scene where Qin Weiwei was killed again."

Generally, murder scenes are kept for a long time.

"This is the set-top box used by Qin Weiwei's home TV. This set-top box is a machine that integrates TV signals and network signals."

In the process of investigating a case, it is common to return to the scene multiple times for inspection.

"There are a total of six devices connected to Qin Weiwei's WiFi signal."

"In addition to a TV, there are five cell phones."

"Gao Wenxiang has already conducted a thorough investigation this afternoon.

Among these five mobile phones, one belongs to Qin Weiwei herself, another belongs to her ex-boyfriend Zheng Gaoxue, and the other two belong to her best friend who once came to her house and connected to his WiFi. "

"There is also a mobile phone..."

Lu Chuan flipped through the PPT again: "When we were at the crime scene today, this mobile phone was still connected to Qin Weiwei's home WiFi."

"Dong Jun's?"

Wang Zhaokai was deeply surprised.

Gao Wenxiang took over: "Dong Jun's mobile phone was not checked, but it should be his."

"Because after we found out about this incident this afternoon, we conducted another investigation and visit to the upstairs, downstairs and the opposite door."

"No one is downstairs. There must be no one connected to Qin Weiwei's WiFi. There is an 80-year-old man upstairs who doesn't know how to use it."

"Only Dong Jun, who lives opposite Men'er to the deceased, is at home, and when we went there, we checked carefully and found that his home did not have WiFi equipment."

"Is it possible that it's Internet fraud?" someone asked.

"That's a good question. I was also thinking at the time that there were indeed many cases of neighbors using the Internet, but when I checked the screencasting records of Qin Weiwei's TV..."

Lu Chuan flipped through the PPT and a list appeared.

"The TV at Qin Weiwei's home is a network smart TV, which can mirror the screen to the mobile phone, as long as the TV and mobile phone are in the same WiFi area."

"This is the most recent screencast record, which took place at 3:30 in the morning on the day of the incident."

"The playback record shows that the horror movie ghost knocks on the door!"

“And the phone that’s mirroring the screen is none other than Dong Jun’s phone!”

Ok?
After everyone heard this, they all knew what was going on.

“Dong Jun lied?”

Correct!
According to Dong Jun, around 3:30 in the morning when the incident occurred, he heard screams from the opposite door and calls for help.

Then he knocked on the door opposite. Qin Weiwei inside said she was watching TV.

This is a problem.

If the screen projection comes from his mobile phone, the content played on the TV is also played by him.

Doesn't that mean he lied?
Lu Chuan confirmed Chen Jiang's question.

Moreover, he had another guess.

"Qin Weiwei died because of a massive cerebral hemorrhage caused by fear, which ultimately led to her death."

"What we are more confused about is why Qin Weiwei was scared to death?"

"What did she see? Or what happened?"

"I guess there are three reasons."

"First, the font on the bathroom mirror: Give me back my life."

"Qin Weiwei got off work late that day. According to the information provided by her colleagues in the company, it was already past one o'clock in the evening when the other party left the company."

In fact, Qin Weiwei went to work late. She only left home to go to work in the company after meeting Zheng Gaoxue in the afternoon.

"The words written by the victim on the bathroom mirror will appear slowly after being fumigated with water vapor."

"Just imagine what it would be like if Qin Weiwei saw these words on the steam mirror in the bathroom when she went home to take a shower."

"At the same time, if the black box that controls the current on and off in the distribution box downstairs starts working at this time, the lights in the house will flicker."

"In addition, the ghost movie suddenly played on TV: The Ghost Knocks on the Door..."

"Is it possible that Qin Weiwei became extremely emotional due to these reasons, leading to a recurrence of old illnesses and cerebral hemorrhage?"

Lu Chuan's guess...

It's really possible.

This case, judging from the cause of Qin Weiwei's death, actually fits the characteristics of an accidental death.

If the murderer hadn't moved the body in the end, the police might not have discovered that the other party was killed.

One is the writing on the bathroom mirror. If Lu Chuan hadn't been on site to conduct an inspection, most people wouldn't have been able to spot it.

Second, the whole room is airtight. Generally speaking, Qin Weiwei locked the door by himself and died of cerebral hemorrhage.

As for the time of death, cerebral hemorrhage is different from ordinary death.

Acute cerebral hemorrhage will not kill people immediately.

This requires a time process.

Generally speaking, two or three hours are available.

It is not impossible that Qin Weiwei suffered a cerebral hemorrhage at 3:30 but died at 5 o'clock.

Although what Lu Chuan was doing was just speculation and there was no substantial evidence, it made sense logically.

"Army, arrest people now?"
