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

Chapter 702 Post!

Chen Xiao was sitting in the room.

He held the portrait in his hand and did not move for a long time.

The only person who fits the image of a young man in the case is Sang Xiaoming.

Sang Xiaoming also has a very special position in the case.

Because after the deceased came to Xiaozhuangnan Town, he had contact with him and even had a conversation with him.

However, there was no valuable information in Sang Xiaoming's confession.

This does not mean that Sang Xiaoming lied.

He was a student, and it was very reasonable for his father to invite his tenant Yuan Keyu to teach him some academic knowledge.

However, who activated the surveillance camera of Sang Yupeng’s rented house?

Although it is not difficult to operate the surveillance camera, and watching the video, it does not look like a fake image.

Therefore, the problem with the video, or to put it simply, the illusion of a murder in a closed room, is simply the swapping of surveillance footage.

The fourth and sixth floors were swapped.

The actual probe on the fourth floor had already broken down and had no image.

This resulted in a nearly perfect closed-room murder case.

The more Chen Xiao thought about it, the deeper his thoughts became.

Time passed unknowingly and it was already early morning.

That night, nothing happened and no news came.

When Chen Xiao felt relieved and wanted to take a nap, Xie Wensheng called.

Chen Xiao answered the call immediately.

The person who called Xie Wensheng could only be a technician in the company. He found the forum and even the conversation between the deceased and the murderer.

"Hey, Brother Sheng, is this good news?"

"I guess so. When I received your call last night, I asked all the technical staff in the company to work overtime and search for clues on the Internet. It was not until half an hour ago that a young man found the Professor Yuan you mentioned in an academic forum."

"According to Professor Yuan's ID, he found a suspicious person in another forum. It was a reply on the same floor, and the website was also a domestic forum website."

"In the conversation on the floor of that post, there is a discussion about a problem, and the time of the conversation in the post is also after I returned to China. I will send the screenshots taken by the technicians to your computer now, and you can check whether the conversations are suspicious. If they are suspicious, then we need to ask the relevant departments to intervene and connect with the website to see if they can provide an account to find the private chat records of the two people."

Chen Xiao listened while looking at the content sent by Xie Wen Zheng.

Chen Xiao couldn't quite understand the content, because 90% of it was about discussions of issues.

Moreover, the discussion did not produce any results. The two sides only exchanged a few sentences before the discussion came to an abrupt end without any further developments.

They were chatting enthusiastically at first, but suddenly there was no follow-up. This is why Xie Wensheng suspected that the two parties had a private chat.

After reading it, Chen Xiao immediately said, "Okay, I will notify the task force now and ask them to contact the website."

After saying that, Chen Xiao was about to hang up the phone, but immediately he said:
"Brother Sheng, thank you for your hard work."

"Don't think too much. I didn't stay up all night waiting. I got a call from the technician this morning, so I got up and called you back."

"That's good. You have to take better care of your health! Oh, by the way, when you pay salaries this month, remember to give that technician a bonus. Also, observe him for a period of time. If his performance continues to be good, give him a recommendation!"

"Don't worry, I have noticed all the capable people."

After hearing what Xie Wensheng said, Chen Xiao said no more.

The information provided by Dong'an technicians is what needs to be checked as a matter of urgency.

After hanging up the phone, Chen Xiao immediately got up and went to find Qin Fei.

While the latter was washing up, Chen Xiao informed him of the information he had obtained. Qin Fei wiped his face and said in surprise:

"It was right to ask you for help. And I suddenly feel that a lot of changes have taken place from this case. Especially our means of investigating cases can no longer be limited to the previous ones. The Internet is also a very important place!"

Chen Xiao just smiled, but soon he asked:
"You have no other news all night?"

"No, nothing happened last night, otherwise I wouldn't have slept till this hour!"

Qin Fei said this, and left the residence with Chen Xiao to find Cao Xiuyuan.

The latter did not sleep all night and did not return to his residence. Instead, he spent another night investigating traces at the crime scene.

When he saw Chen Xiao and Qin Fei coming, Cao Xiuyuan put down the work in his hands.

However, he first took out his cell phone and put it aside, then motioned for the two to talk outside.

Chen Xiao took a look and went out silently.

As soon as Cao Xiuyuan came out, he immediately asked, "You two came to see me at this time, did you make a major discovery?"

"The technicians of Chen Xiao's company have found the communication information between Professor Yuan and the murderer, but the information is very limited. We need the police to contact the website to retrieve their private chat information."

Tan Fei explained to Cao Xiuyuan.

Upon hearing this, the latter asked with surprise, "Is it a domestic forum?"

"Yes, and the communication between the two of them took place after Professor Yuan returned to China."

"Okay, tell me the name of the website and I'll have someone intervene now."

Chen Xiao had already made preparations and gave Cao Xiuyuan the company to which the website belonged, as well as the website's contact information.

The latter was about to get his phone when he got it, but he suddenly realized it and smiled bitterly:

"My phone has been tampered with, but I'll tell you about it later. Qin Fei, give me a call on your phone."

Qin Fei nodded and handed over his work phone.

Cao Xiuyuan took the phone and went to the side. A few minutes later, he came back after finishing the call. Without waiting for Chen Xiao and the others to ask, he took the initiative to say:

"It was an accident that I found out that there was something wrong with my phone. Not long after I came to Xiaozhuangnan Town, my phone broke inexplicably, so I went to the repair shop to have a look."

"The repairman found the problem as soon as he opened it. I told him I was a police officer before I contacted him, so he was very alert and told me through text that my phone had been bugged."

Qin Fei couldn't help but be surprised: "Isn't your phone always close to you? How could someone install a wiretap device on it without making any noise?"

"It can be considered as being carried close to my body, but it is not absolutely with me 24 hours a day, so there must be a place where someone has taken advantage of it. Moreover, the equipment in my phone is very powerful. People told me that it is definitely a state-of-the-art micro-eavesdropping device!"

When Cao Xiuyuan said this, he looked at Chen Xiao.

Chen Xiao seemed to understand what he meant by this look and said:

"Captain Cao, you don't have to look at me like that. If you don't plan to tell us everything you know, we won't ask too many questions."

Hearing what Chen Xiao said, Cao Xiuyuan was obviously stunned for a moment, then smiled bitterly and said:
"I'm sorry, after I found out there was something wrong with my phone, it was hard for me to trust anyone. Of course, I was the one who asked you to come here, so I really shouldn't have been wary of you."

Cao Xiuyuan's words also meant that he wanted to take this opportunity to have an open-hearted chat with Chen Xiao and the others.

But at this moment, Cao Xiuyuan's cell phone in the room rang.

Walking into the house, Cao Xiuyuan answered the phone:
"Hey, Lao Sun, what's wrong?"

"Lao Cao, can you contact Xiao Hai?"

When they heard Sun Zhou's voice in the microphone, Chen Xiao and Qin Fei's faces changed drastically.

Qin Fei, in particular, asked hurriedly, "Who is Xiao Hai? Could he be a member of our task force?"
