Fourth floor.

Cyber ​​Police Brigade.

Guan Feng stepped forward and asked, "Any clues?"

Gao Dacheng pointed to the backstage area and said, "This is Chen Qian's official account; it was suddenly discontinued three months ago."

Guan Feng said, "I was just about to tell everyone that the victim's identity has been confirmed. Through DNA comparison, it has been confirmed that the victim is Chen Qian."

Gao Dacheng said, "No wonder! That's perfect! We contacted Weixin Company and found that Chen Qian was chatting frequently with this user named Xixingemian. The chat started half a year ago and ended three months ago."

Guan Feng asked, "What is the identity of the person who has turned over a new leaf?"

Gao Dacheng said, "We've checked! It's a man named Li Ziqiang, who's from Hua'an."

Guan Feng asked, "Does it match the detected DNA?"

Gao Dacheng shook his head and said, "Not a good match!"

Guan Feng asked, "Then what was the point of suspicion just now?"

Gao Dacheng explained, "We just retrieved all the relevant contacts, especially those the victim contacted in the week before her death, and discovered a peculiar phenomenon: Chen Qian had financial dealings with multiple men before her death."

"Economic exchanges?"

Guan Feng asked, "How big?"

Gao Dacheng said, "It's not much, just transfers of three or five hundred, but even so, I feel there's something wrong with it."

Guan Feng couldn't help but become alert upon hearing this number.

Looking at Chen Qian's data trajectory chart, he said, "Chen Qian has been married twice, both ending in divorce. The information here also shows that after her divorce, she chatted more frequently, her activity range expanded, and she even used dating apps like suol."

Gao Dacheng asked, "Then we need to retrieve the information of the parties involved?"

Guan Feng nodded and said, "Let's summarize and sort things out first, and see how many people are involved."

Half an hour later.

Information about the relevant personnel was compiled.

A total of 23 users made transfers.

Most of them are concentrated around Jiangnan Province.

Guan Feng stared at one of the messages and asked, "Is there one from Hua'an as well?"

Gao Dacheng said, "It's this Li Ziqiang! He transferred 500 yuan a month before Chen Qian died. By comparing Chen Qian's data, we found that he was in Hua'an at that time."

Guan Feng said, "In that case, let's investigate this person first."

......

Hua'an.

The First Municipal Hospital.

Guan Feng revisited the place and recalled the scene of getting the injection. A thought flashed through his mind, and he asked Gao Dacheng, "Are you sure the other party works here?"

Gao Dacheng said, "That's what it says on the retention information!"

Guan Feng said, "Let's go in and take a look."

He didn't inform the other party beforehand because he was afraid of alerting them and affecting the effectiveness of micro-expression analysis.

The group arrived at the outpatient department.

Guan Feng walked to the information desk and asked where the radiology department was.

The nurse on duty described the address and pointed it out briefly, and Guan Feng led the group straight to their destination.

A moment later.

Second floor, radiology department.

Guan Feng stared at a figure behind the window, and after confirming for a moment, nodded and said, "That's him! Let's go and ask him what's going on."

Several people walked up.

Guan Feng asked, "Are you Li Ziqiang?"

Li Ziqiang, wearing a white coat and a mask, glanced at the group and asked, "That's me! What are you doing here?"

Guan Feng simply took out his identification and showed it to the other person, saying in a somewhat serious tone, "We are police officers, and we've come to ask you a few questions."

Li Ziqiang looked somewhat surprised and asked, "Police? What do you want with me? I haven't done anything wrong!"

Guan Feng said, "The police looking for someone isn't necessarily a bad thing. It's possible that you've unknowingly gotten involved in some things. Are you free now? We need to ask you a few questions, and we hope you'll cooperate."

Li Ziqiang glanced outside the office and nodded, saying, "Alright, come in. We'll pause when there are patients, okay?"

Guan Feng nodded and said, "Treating the sick and saving lives is naturally the top priority."

The three of them entered the room.

Huang Lili turned on the recorder on her shoulder.

Guan Feng asked, "Are you a doctor in the radiology department of the First Municipal Hospital?"

Li Ziqiang said, "Yes, I'm in charge of the radiology department, not a police officer. What's the matter? Why are you so serious?"

Guan Feng asked, "Do you know Chen Qian?"

"Chen Qian?"

Li Ziqiang thought for a moment, then shook his head and said, "No!"

Guan Feng asked, "Think about it again! The other person's online name is Red Rose."

Li Ziqiang's expression changed immediately. He subconsciously glanced at Guan Feng and said evasively, "I...I don't remember."

Guan Feng asked, "No recollection? This doesn't match the information we've gathered, does it? Li Ziqiang, I need to remind you, the body camera is on. If you lie or deliberately mislead the police, you'll be held legally responsible. What might have been a minor offense could become a serious one if you lie!"

Li Ziqiang asked, "Maybe...maybe it will take too long. Can you remind me?"

Guan Feng said, "Four months ago, you transferred 500 yuan to the other party."

Li Ziqiang asked, "Is it prestige?"

Guan Feng said, "Yes!"

Li Ziqiang said, "Let me look for the records."

A moment later.

I found a record from four months ago on my phone.

He pointed to the blank space and shook his head, saying, "No? Are you sure you're not mistaken?"

Guan Feng, too lazy to beat around the bush, said directly, "The record can be deleted, but the backend cannot. We retrieved this transfer record directly from the backend. Don't think you can get away with it by deleting it. Or do you think you don't want to talk about it here and want to come back to the station with us?"

Li Ziqiang swallowed hard and said, "Actually, it's nothing. I remember this red rose. We chatted online for a while and got to know each other. She came to visit me, and I gave her 500 yuan for travel expenses."

Guan Feng asked, "Why did you hide it just now?"

Li Ziqiang sighed and said, "Isn't it because I was afraid you'd misunderstand?"

Guan Feng asked, "Think carefully about Chen Qian's state at the time, and recall the scene when you first met her, right from the beginning?"
