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

Chapter 685 Key person!
The case of Yuan Keyu’s murder.

Chen Xiao got a lot of information from Cao Xiuyuan.

But that's all the information there is and it's not very helpful in solving the case.

So Chen Xiao had already made up his mind that he needed to verify more information about the case on his own bit by bit.

Only what you find out yourself is the most reliable.

When Sang Yupeng heard Chen Xiao's question, he looked very strange:
"Didn't the police officers go to the school to look for my son a long time ago? My son didn't know anything about these things. It's my fault. When I first met Mr. Yuan, I wanted to take advantage of him, but who could have thought that he would encounter such a thing!"

"And do you know what the officers asked him?"

Sang Yupeng shook his head: "I don't know about that. Besides, my son is now a senior high school student and rarely comes home. He has been studying hard in school."

As he spoke, Sang Yupeng also asked with some concern:
"Consultant Chen, Captain Qin, I would like to trouble you, the police, too. My child is in his third year of high school, which is the most important stage in life. And he is just a child and knows nothing. So can you, the police, try not to look for him?"

"I'm worried that this will have a great impact on his studies!"

Chen Xiao could understand the parents' feelings very well.

If he were Sang Yupeng, he would also be distressed by his experience. Especially since there is a senior high school student at home who is facing a critical period in his life, he would not want him to be questioned by the police.

"We will try our best, and Mr. Sang, rest assured that even if we ask him, we will choose a time outside of his studies."

Sang Yupeng smiled and nodded.

After Chen Xiao looked at the lists again, he told Sang Yupeng that he had asked all the questions he needed to ask.

Upon hearing this, the latter found an excuse and left first.

As soon as he left, Tan Fei took the initiative to say:
“The people on this list should be questioned.”

After thinking for a while, Chen Xiao shook his head and said:
"I think the questioning of these people can be postponed."

Qin Fei was very puzzled.

The reason the crime scene was renovated and monitored was because of a fire.

The cause of the fire was arson by someone else.

Not to mention the police, even ordinary people know what a fire would cause. If there are still people inside such low-rent areas, they will definitely be killed or seriously injured.

Thinking of Yuan Keyu's peeled skin, Qin Fei felt that those injured people needed to be questioned.

However, Chen Xiao objected, and Qin Fei did not rush to express his thoughts, but waited for Chen Xiao to explain.

Soon, Chen Xiao figured it out and replied:

"We are the last to see this list, so the victims should have been questioned. There shouldn't be any major problems here, and we probably won't get anything special if we ask them."

As Chen Xiao was talking, Qin Fei suddenly felt a headache:
"You're right. This case gives people the feeling that there are many, many questions, but there is no way to answer them."

Then, Qin Fei mentioned Sang Xiaoming again: "But Sang Yupeng's son has also been questioned. Are we going to let go of the landlord?"

Chen Xiao's original plan was to focus his attention on Sang Xiaoming.

Because from Sang Yupeng's words, Chen Xiao can be sure that Yuan Keyu and Sang Xiaoming have contact. And a mysterious tenant, according to common sense, even if the landlord has requested it, it is impossible for him to meet the other party's child on the day of renting the house.

Besides, Yuan Keyu must have something to do here.

So, if we think about these points together, Yuan Keyu has no reason to meet Sang Xiaoming.

Thinking of this, Chen Xiao asked, "Have we missed anyone?"

"Even Sang Yupeng's son has been taken into consideration, who else could be left out?"

"Don't be impatient, let's go over it again. I'll ask the questions and you answer them." Chen Xiao said, and he spoke directly without waiting for Qin Fei to respond:

"Yuan Keyu came to Xiaozhuangnan Town without stopping, and went straight to Sang Yupeng to rent a house. What does this mean?"

Qin Fei: "This means that when he decided to come to Xiaozhuang South Town, he had an accurate target for the location."

"Then why is it Sang Yupeng's house? And as a new tenant, he went to meet Sang Yupeng's son on the first day he rented Sang Yupeng's house?"

"He could have promised Sang Yupeng that he would tutor Sang Xiaoming, who is in his third year of high school, in his free time. Why did he do it on the first day?"

"Yuan Keyu came to Xiaozhuangnan Town without telling anyone. Shouldn't he have come here for people and things?"

After Chen Xiao finished speaking, Qin Fei's eyes widened instantly:

"So, the person Yuan Keyu wants to meet might be Sang Xiaoming!"

Chen Xiao did not respond immediately, but stretched out his hand to signal Qin Fei not to be anxious.

“It may not be Sang Xiaoming, but it is possible that he is related to Sang Xiaoming.”

"Then we need to focus on questioning Sang Xiaoming."

"Again, the task force that should have asked the question has already asked it before us. But we didn't see any relief on the faces of Captain Cao or the task force detectives we met at the office."

"We can infer from this that the task force did not obtain any valuable information from Sang Xiaoming."

"In the special case team, there is Cao Xiuyuan, who is good at trace examination, and Director Chang, the most famous forensic doctor in the province, as well as Captain Sun from the Jingzhou City Police Criminal Police Team who is also good at questioning and interrogation."

"So, do you think that our questioning of Sang Xiaoming can be more incisive than Captain Sun's? I don't think so!"

Chen Xiao paused and squinted his eyes as he said, "Captain Qin, the only person we officially met when we came to the task force was Captain Cao. As for the others, they didn't care about our presence at all. And we actually didn't know all the details of many cases."

"So, we can use their performance to save time. Sang Xiaoming is important, but Sang Xiaoming himself is not important. What we need to do most now is to sort out his interpersonal relationships."

Listening to Chen Xiao's words, Qin Fei's mind also flashed with inspiration:
"If we can find a person who matches Sang Xiaoming's face, scalp, facial features and other factors from his interpersonal relationships, then he will become an extremely important person involved in the case!"

Chen Xiao immediately snapped his fingers at Qin Fei:
"This idea is correct. After killing Yuan Keyu, the murderer not only peeled off his skin, but also shaved off his hair and took it away. There must be a direction here."

Qin Fei nodded: "Okay, I'll sort out the relationships, and then I'll go and investigate one by one. Besides, he's a student, and besides his family, his biggest circle of relationships is in school, so that person won't be hard to find!"

Chen Xiao hummed.

Just looking out the window, Chen Xiao said softly:
"In fact, I really want to meet the family of the deceased Yuan Keyu in person, and the people who invited him to return to serve the country!"
