Chapter 758 Clues
The projection is personal information about Dong Jun.
Lu Chuan looked at it carefully and studied 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.
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 there is nothing normal, he Just stay at home.”
"Team Lu, this is the basic situation."
Lu Chuan nodded. There was not much information, but it had certain reference value.
"Liant Lu, do you suspect that Dong Jun... has a problem?"
Wang Zhaokai knew that there must be a reason why Lu Chuan suddenly investigated Dong Jun.
“I found something at the scene, something very interesting.”
Lu Chuan asked Gao Wenxiang to project what he discovered just this afternoon on the screen.
"This afternoon Gao Wenxiang and I went to the scene where Qin Weiwei was killed again."
This is considered a routine operation.
Generally, murder scenes are kept for a long time.
In the process of investigating a case, it is common to return to the scene multiple times for investigation.
Sometimes handling a case requires not only inspiration, but also luck.
Every on-site inspection is actually equivalent to turning the entire site upside down.
But there is always something missing.
Just like the first time Lu Chuan went to the site to investigate, and the second time he went to the site, he found different things.
What is shown in the projected photo is Qin Weiwei’s set-top box.
"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."
"Judging from the preliminary investigation results, the person who killed Qin Weiwei should be familiar to her "
"So is it possible that this acquaintance has connected to Qin Weiwei's home WiFi signal? "
Lu Chuan operated the projection to display the next photo.
“This afternoon, when I was at the scene, I cracked the data signal in the set-top box and made a detailed analysis.”
"I found something interesting, let's take a look..."
The video shows a series of mobile device information connected to Qin Weiwei's home set-top box.
“There are a total of six devices connected to Qin Weiwei’s WiFi signal.”
“In addition to one TV, there are also five mobile phones.”
“High in the afternoon Wen Xiang has already done a thorough investigation.
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 this afternoon, we checked again upstairs, downstairs and the opposite door. Investigate and visit. "
"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 lived opposite the deceased, was at home. When we went there, we noticed that his home did not have WiFi equipment. "Is it possible that the Internet was being used?" someone asked.
“That’s a good question. I was also thinking at the time that there were indeed many incidents 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 latest news A screencast was recorded 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!"
"The mobile phone that projects the screen is none other than Dong Jun's mobile phone!"
Huh?
After everyone heard this, they all knew what was going on.
“Dong Jun lied?”
right!
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 this screen projection comes from his mobile phone, the things played on the TV are also played by him.
Doesn't that mean he lied?
Lu Chuan confirmed Chen Jiang’s question.
Moreover, he had another guess.
“The cause of Qin Weiwei’s death was fear of massive cerebral hemorrhage, which eventually led to death.”
“What we are more confused about is why Qin Weiwei was scared to death?”
< br>
"What did she see then? 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 also got off work late. , she 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 slowly appear after being fumigated with water vapor."
"Just imagine, if Qin Weiwei goes home to take a shower. These water vapor words appear on the mirror in the bathroom What kind of situation did she see when she saw these words? "
"At the same time, if the black box that controls the current on and off in the distribution box downstairs starts to work, the lights in the house will flash. "
"Coupled with the sudden playing of a ghost movie on TV: 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.
First, the words on the bathroom mirror would have been impossible for most people to spot if Lu Chuan hadn't been on site to investigate.
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 had a cerebral hemorrhage at 3:30 but died at 5 o'clock.
Although what Lu Chuan was doing was just speculation without substantial evidence, logically speaking, it makes sense.
"Army, arrest people now?"
