I'm a street kid, but my wife, a policewoman, won't divorce her

Chapter 682 He has a big problem!

If it were an ordinary person, after hearing what Chen Xiao said, it might take a while to sort it out.

After hearing this, Qin Fei immediately understood.

"The files show that Yuan Keyu died between 11 and p.m."

"The total time period of death was three hours, but the time between 11 and was just an approximate time given by the medical examiner."

"According to the current level of forensic identification, this time can actually be extended a little bit forward or backward."

"If I remember correctly, the case file records that Yuan Keyu appeared in the corridor at 7:26 p.m. on the night of the incident and opened the door to go in. He left at 37: p.m. the previous time."

"This is the last time he left the rental house and the time he returned to the rental house. Could it be that the last person we saw was not Yuan Keyu?"

Qin Fei explained his own reasoning based on Chen Xiao's hypothesis.

After saying that, Qin Fei immediately said:
"But that doesn't make sense. If Yuan Keyu was killed somewhere else and then brought back, then how was his body brought back?"

"Although we can't clearly and completely identify that it is Yuan Keyu from the surveillance, if there are two people, even if one is dead, we should at least bring him in."

Chen Xiao nodded: "Yes, from the surveillance, Yuan Keyu went out alone several times, and he didn't carry anything with him."

"This means that we can completely rule out the possibility that he was killed somewhere else and then brought back to the crime scene to commit murder in a closed room."

Chen Xiao seemed to be making a summary.

But this summary made Qin Fei even more confused.

"No, you've got me completely stupefied. You've proposed a possibility that doesn't stand up to scrutiny."

Qin Fei smiled bitterly, and Chen Xiao pursed his lips:
"I made this assumption not to prove that what I said was right, but to verify multiple possibilities."

"What we just analyzed was the topic surrounding people. Since the reasoning surrounding people is untenable, it means that there is no problem with people, right?"

Tan Fei nodded: "Yes."

"Since there is no problem with the person, is there a problem with the time?"

"The time we are targeting is all about capturing Professor Yuan."

"If that's the case, then time is no problem. People are no problem, time is no problem, but what about space?" Chen Xiao asked, and Qin Fei paused:
"Space is low-cost housing, where does the problem come from?"

"But there must be something wrong. Otherwise, who would have killed the person? How could a living person do such a perfect murder in a secret room?"

Chen Xiao asked back.

Qin Fei felt a headache and didn't know what to say.

Chen Xiao stood up, patted his shoulder and said:
"It's hard to describe the pixels of the surveillance. Let's wait until Dong'an optimizes the video before we take a look. Now let's look for loopholes in the space."

Chen Xiao felt that they were not completely passive when it came to the issue of murder in a closed room.

At least, they were sure there was a place the murderer had used.

Qin Fei did not ask any more questions. When he saw Chen Xiao walking out, he could not help but ask:
"Don't you want to ask your brother to go with you?"

"He has also encountered a problem. It is best not to disturb him until he finds the answer."

Liu Dayou has been looking worried ever since he got Cao Xiuyuan's birth date. Chen Xiao knew that he must have encountered a big problem.

Liu Dayou encountered a difficult problem, which Chen Xiao could not help with. He could only let him figure it out and analyze it slowly on his own.

I left Xiaozhuangnan Town Police Station with Qin Fei and soon arrived at the building where the crime scene occurred.

The exterior style of the building is almost identical to Aunt Cai's house, and even the floor heights are exactly the same, both are six stories high and have no elevators.

All the tenants in the building are people who came to Zhushan City from other provinces to work.

These people either work as migrant workers on construction sites or do assembly line work in factories.

Either the salary is not high, or the salary is good but the people are extremely frugal.

Qin Fei wanted to go upstairs from the entrance, but Chen Xiao grabbed him and said:
"There's no rush to go in, let's start from the outside."

Qin Fei understood what he meant. He wanted to have the most comprehensive understanding of the surrounding environment.

After all, looking around from the bottom of a building and looking around from the top of a building, even if the scenery is the same, the angles are different, so perhaps the understanding will be different.

Chen Xiao and Qin Fei walked around the area.

After returning downstairs, Qin Fei took the initiative to say:
"The houses around here are all old buildings, and there are not many high-rise buildings. The average number of floors in the buildings is about two to three, and the ones that are higher are obviously added later. It seems that many people here have a keen sense of smell, and they will get more after the demolition of the houses when the floors are raised."

"The other four areas are all low-rent areas. I asked someone about this area and found out that it was only established a short time ago, only five or six years ago."

"Before this, the whole area could only be considered an urban village. Most of the people in the village were fishermen, but now they either run small workshops or make a living by collecting rent. There are fewer fishermen than before."

After Qin Fei finished speaking, Chen Xiao suddenly said:
"From the transcript of Professor Yuan's wife, it seems that there is a record that Professor Yuan's favorite leisure activity is sea fishing, right?"

"Yes." Qin Fei replied without hesitation, which also meant that he had already thought of this when he told Chen Xiao the information about the nearby fishermen, and added:

"There is also a part of the business here that takes tourists out to sea for fishing. Of course, there are not many such businesses, and they are only popular among wealthy people."

In today's era, the tourism industry is not as hot as it will be in later generations.

In the future, places near the sea like this will attract many tourists from all over the country by promoting them through a movie or some unique feature of the scenic spot.

At present, in Xiaozhuangnan Town, which is similar to a town within a city, most people’s income comes from small processing factories.

It is precisely because of the existence of these processing plants that many migrant workers were attracted, thus contributing to the formation of low-rent areas.

After gaining a special understanding of the local area, Chen Xiao and Qin Fei did not continue to wander around the periphery, but went upstairs.

Qin Fei’s goal was very clear, he wanted to go directly to the sixth floor.

But Chen Xiao stopped at the stairs on the second floor: "Don't worry, let's take a look at the layout of each floor. The crime scene is a densely populated area with tall buildings, and each building is close to each other. Therefore, we need to fully understand the situation on each floor. Only in this way can we find the problem with a greater probability in space."

Chen Xiao is very patient.

After being reminded, Qin Fei also felt the gap between himself and Chen Xiao.

Just when the two of them walked into the corridor and looked up at the surveillance camera, Liu Dayou's phone call came in.

"Hey, Brother Chen, I figured it out. Captain Cao...he has a big problem!"
