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

Chapter 681 Monitoring, hypothetical reasoning!
Who is Qin Fei looking for?

Chen Xiao didn't know and didn't ask.

Seeing Liu Dayou taking the birth data, Chen Xiao stopped paying attention and continued watching the video footage.

When he arrived at Xiaozhuangnan Town, what he was most interested in was what the surveillance camera had captured on the day of the incident.

Chen Xiao sat in front of the computer, without speeding up, just watching frame by frame.

Not long after, he saw Yuan Keyu appear at the door of the rental house.

Yuan Keyu seemed to look at the door of the rental house, then took out his mobile phone and made a call.

From the surveillance camera's angle, it was also possible to capture a piece of white paper posted on the door of the rented house.

There are a few words written on the white paper. Although the camera pixel is very poor, the words should not be difficult to recognize.

It should be something like “House for rent, phone number ***…”

Chen Xiao noticed the time and shouted to Qin Fei:

"The task force didn't tell us a lot of things."

Qin Fei sat back down and asked, "Are you referring to the interrogation of Sang Xiaoming, the son of the landlord Sang Yupeng?"

"More than that. Logically, it's been almost a day and a night, and the police should have finished questioning Sang Xiaoming. But Captain Cao didn't tell me about the latest situation, which means that either he felt he shouldn't tell us, or they haven't seen Sang Xiaoming yet."

"That shouldn't be the case. Sang Xiaoming is a senior high school student. He can find it immediately by going to school."

"So I said the task force was very strange. Then there's the timing. Did you notice that there was something wrong with the time when the deceased Yuan Keyu appeared in the video?"

Qin Fei frowned immediately, and after looking at the time, he reacted soon:
"You mean, no one in the file has a record of the time when Professor Yuan Keyu showed up at the rental house. At this point in time, if we calculate from the time Professor Yuan arrived in Xiaozhuang South Town, he arrived almost without any delay."

"Yes, that's why I said this time is very problematic. His purpose is very strong, which further proves that Professor Yuan has a very unusual relationship with that house."

"Besides, unless there is a real accident, I don't think Sang Xiaoming's inquiry is over yet."

Chen Xiao said this and looked at Qin Fei with a slightly serious expression.

Qin Fei's mood was not very good at this time.

The task force is not united, which is obviously not a good thing for the investigation of the case.

Moreover, although most of the members of the task force came from Cao Xiuyuan's team, some came from other units.

After all this, everyone who should have been united in purpose now has their own thoughts.

"How about I contact my superiors and explain the situation of the task force?" Qin Fei asked tentatively.

Chen Xiao shook his head: "You are not Cao Xiuyuan. Even if you have a good relationship with the higher-ups, you are not the one to talk about this matter. I brought this up just to ask Captain Qin, how do you want to handle this case?"

"What can I do? Of course I will investigate to the best of my ability."

"Let's put things in perspective. Investigating the case is our responsibility. But once the case is solved, how do you think the credit should be handled?"

"That depends on who found it out. But no matter who found it out, everyone will be commended if it is discovered." Qin Fei smiled.

Chen Xiao narrowed his eyes and asked, "What if it's not broken?"

"Don't worry if it's not broken, we'll just do our best."

"But I think this case has dragged on long enough. If it goes on any longer, someone will have to take the blame."

Chen Xiao reminded him, but Qin Fei didn't reply for a while, and a hint of worry appeared in his eyes.

But Chen Xiao quickly changed the subject.

He just mentioned the issues outside the case.

What he cared about most was the case itself. As for the final result of the case, it had nothing to do with him as a civilian detective.

No matter what, it is not his turn as a criminal investigation consultant hired by the police to take the blame for this matter.

Can't convince the public.

Chen Xiao gathered his thoughts and continued watching the surveillance video.

However, he began to recall Huang Hao’s words in his heart.

Huang Hao mentioned the three points of time, place and people.

To determine whether there is a problem with the timing, we need to check the time when the victim appears.

Secondly, the location, in Chen Xiao's opinion, is whether there is a problem with surveillance and whether the secret room is a real secret room.

There seems to be no problem with these two points at the moment.

If we have to find a problem, the problem of timing simply refers to the fact that Yuan Keyu is very goal-oriented.

The problem with geographical advantages lies in the clarity of the monitoring itself.

The people who appeared in the surveillance video include the landlord Sang Yupeng and the deceased Yuan Keyu.

But with today's equipment, and in order to save money, low-rent housing landlords cannot purchase overly expensive and sophisticated surveillance.

Therefore, we can only say that the person in the video looks more than 95% like Yuan Keyu.

No one dares to say 100%.

Chen Xiao thought about it, and just to be cautious, he picked up his phone and called Cao Xiuyuan.

"Hey, Captain Cao, can I make a copy of the surveillance data and send it to a professional place to repair it so that it is clearer?"

"can."

Cao Xiuyuan on the other end of the phone paused for a second, then agreed to Chen Xiao's request.

Chen Xiao quickly copied it and called Xie Wensheng again:

"Brother Sheng, I sent a piece of surveillance data to your email. Please ask the company's technical staff to optimize it and see if the clarity of the surveillance can be improved."

"Ok."

After the arrangements were made, Qin Fei also noticed Chen Xiao's intention and asked:
"Are you suspicious of the person who appeared in the surveillance video?"

Chen Xiao smiled and said, "During the time I have been in Xiaozhuang South Town, I have been thinking about how to create such a perfect closed room murder case."

"And, in order to better prepare in advance, I rented Aunt Cai's room. But after thinking it over, I still don't think that human power can really accomplish the murder case we have seen."

"Many closed-room murders use either time or space to make people see what they want them to see."

"The biggest problem we are facing right now is that the murderer has never appeared in the surveillance footage, and there is no sign of anyone escaping from the house. So, how did that person get here? If we were to make an assumption around this question, how would you go about making that assumption, Captain Qin?"

Chen Xiao asked back. Qin Fei was a little confused for a moment. He thought for a while and shook his head:

"You might as well just say what you think."

Chen Xiao nodded, but subconsciously looked at Liu Dayou who was still thinking about the copper coins, and then said:

"My premise is that if one or two of the several times we see Professor Yuan Keyu in the video are not Professor Yuan, can this closed-room murder case be established?"

"Or to simplify this question further, the deceased Yuan Keyu may have been killed earlier than we thought!"
