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

On the projection screen, Wang Zhaokai magnified the names of three neighbors of the deceased Qin Weiwei.

"And the resident downstairs got up to go to the bathroom. He probably looked at the time and it was around 3:30 in the morning."

"However, the time of death was five o'clock in the morning."

"In other words, if the cry for help made by the deceased is true, then why is there an hour and a half difference between the time of death and the time when the cry for help was made?"

Wang Zhaokai not only questioned the deceased Qin Weiwei's neighbors across the door and upstairs and downstairs, but also questioned all the residents in the unit building.

People in the building reported that everyone had seen Qin Weiwei before, but they were not particularly familiar with her.

"The deceased Qin Weiwei bought a second-hand house in this community two and a half years ago."

"I'm not very familiar with the neighbors in the unit building."

"Most of the impressions about Qin Weiwei are that she is very beautiful and good at dressing up, but there are no other more detailed ones."

Wang Zhaokai operated the projector, which showed the surveillance screen at the gate of the community.

"We retrieved the surveillance video from the surveillance gate of the community."

"This community has a total of two entrances and exits, both with surveillance videos."

"We focused on the monitoring period from 3:30 am to 7 am."

"In the entire community, 18 people entered during this time period."

"There are only two people out."

While Wang Zhaokai introduced the situation, he operated the projector to change the screen.

"We focused on two people who went out. One was accustomed to morning exercise and went out for a run at 5 a.m. every day."

"There is another one who works at the airport and leaves early every day."

Everyone knows the reason why Wang Zhaokai investigated this video.

The deceased was killed at home.

So if an outsider commits the crime, the other person will leave the community after 5 a.m.

However, the surveillance video showed that two people left the community during the 5 a.m. period. One was doing morning exercises and the other was going to the airport for work.

There is a high probability that he will not be the murderer.

and so……

"The murderer is in the community? At least he didn't leave after killing people in the early morning?"

Chen Jiang frowned and said.

Wang Zhaokai nodded: "It's possible."

"Of course, it is also possible that the other party is not in a hurry to leave after killing the people, but waits until dawn before taking action. This is not certain."

"However, because time is too tight, the brothers are still investigating the video after dawn, and there is no result yet."

This is something that takes a lot of time.

Theoretically speaking, as long as the murderer is not a member of the community.

Then the other party will definitely appear in the surveillance at both doors.

In this case, as long as the criminal police team members screen the videos over a period of time and compare them with the owners in the community, they can tell who are strangers entering the community.

"I think we should focus our investigation on the people Qin Weiwei knows."

Sun Biao expressed his opinion.

"No obvious signs of violation were found on the deceased indoors, and there were no signs of being turned over in the drawers and cabinets of her home."

"We even found 10,000 yuan in cash in the drawer of the coffee table in the deceased's house."

"The deceased's jewelry and gold ornaments were not lost."

"Those who seek wealth and kill people, rob and kill people, etc. can basically be ruled out."

"So, there is a high probability that an acquaintance committed the crime. Also, everyone, please pay attention to the text found on the bathroom mirror of the deceased's house. What does this mean?"

"It means that the murderer went to the bathroom of the deceased's house. If he was not someone he knew, how could he go to the bathroom of the deceased's house and leave a message?"

"I agree with Lao Sun." Wang Zhaokai pointed to the person related to Qin Weiwei on the projection.

"I think we can focus on investigating the neighbors across from Qin Weiwei's house."

"According to the neighbors downstairs of Qin Weiwei's house, shouts and calls for help came from Qin Weiwei's house at 3:30 in the morning."

"At such a late hour, the neighbor across from Qin Weiwei's house is still awake."

"What is he doing?"

"I've been to the neighbor's house opposite. Although the soundproofing of this building is average, it's not easy to hear clearly what's going on next door."

"Besides, I checked the identity of Qin Weiwei's neighbor across from him. He has no legitimate occupation."

"I'm in my 30s. I don't have a legitimate job. I don't sleep for most of the year and listen to the advice of the girl next door."

"Moreover, the other party knocked on the door and asked what was going on. Don't you think it's strange?"

"As a normal person, if you heard someone calling for help, especially in the middle of the night, would you choose to call the police or go over to take a look?"

Everyone looked at each other.

Shabi just went over to take a look.

"I think we need to check Qin Weiwei's boyfriend."

Chen Jiang expressed his opinion: "Qin Weiwei's boyfriend is not in Haizhou City now."

"But the time he left was 8 o'clock this morning."

"Qin Weiwei died at 5 a.m., and her ex-boyfriend left Haizhou City at 8 a.m. today. I don't think it's a coincidence."

"According to the information I investigated, Qin Weiwei and her boyfriend did not break up peacefully during the Spring Festival."

"Her boyfriend even went to Qin Weiwei's advertising agency to cause trouble twice."

"And according to Qin Weiwei's best friend, her boyfriend once came to Qin Weiwei's house and blocked Qin Weiwei's door."

"There is a dispute between the two. I think this person needs to be investigated more focused."

After the two expressed their opinions, everyone else also expressed their opinions and comments.

But the possibility of killing for money is basically ruled out.

While Lu Chuan listened to everyone's reports, he recorded something in his notebook.

After more than an hour, everyone's discussion basically ended.

"Have you finished expressing your opinions?"

Everyone nodded.

"Okay," Lu Chuan put down the carbon pen in his hand, "Then let me say a few words."

Everyone straightened their backs and looked at Lu Chuan.

Although Lu Chuan has not been the captain of the Criminal Police Brigade for a long time, he has solved many cases during this period.

"The first thing that can be determined is that this is a criminal case."

No one objected to this, and the writing on the mirror Lu Chuan found in the bathroom was enough to prove it.

In addition, after the death of the deceased, the body was moved from the bathroom floor to the bed, which can also illustrate this point.

"In addition, this case is unusual. Judging from some current clues, this should be a secret room murder case."

Ok?
After Lu Chuan said this, everyone was surprised.

Locked room murder case?

How did it get involved in this?

"You may not have carefully observed the door lock that was picked open by the property owner at the crime scene."

"Xiao Li, play the projector on the current survey photos and look at the one numbered 12."

"Yes!"

After Xiao Li, the technical detective next to him, finished the operation, a photo of the door lock being pried off appeared on the projector. (End of chapter)
