Liu Tianhai's office.

Guan Feng watched Zhang Yong leave, his brows furrowed.

Seeing this, Chen Xuewen asked, "Captain Guan, do you think Zhang Yong is a suspect?"

Guan Feng nodded and said, "The other party's answer just now was too confident, especially when asked if he had done anything similar before."

Chen Xuewen said, "Perhaps the other party is trying to avoid suspicion?"

Guan Feng nodded and said, "That's also possible. I heard that he was able to get into the hospital's logistics department through connections with Director Li. Perhaps the other party is trying their best to deny it in order to avoid this fire spreading to Director Li. Captain Chen, it seems that we can only wait for Wang Xun's results now."

Chen Xuewen said, "Okay, I'll be ready to cooperate at any time."

Guan Feng nodded and went to the next room.

Li Xiangdong and Huang Lili are still taking statements from the doctors in the department.

Guan Feng thought for a moment and then called Chen Yao.

If Zhang Yong's words are true, then the possibility of organ theft is further reduced.

The possibility of rural bad habits being perpetuated is further increased.

This kind of matter is best left to Chen Yao to investigate.

Ring ring!

The call was connected.

Chen Yao couldn't contain his excitement: "Captain Guan, you haven't called me in a while? Is there a mission?"

Guan Feng asked, "I heard that some people around here buy corpses?"

Chen Yao was taken aback for a moment, then realized what he meant and said, "You mean... you know? I have heard of it. It seems like there are quite a few cases like that in Xucheng. What? Is this case related to that?"

Guan Feng said, "Help me find out about the market situation, and also ask if there are any connections in Hongcheng in this regard?"

Chen Yao said, "Okay, I'll go find out right away."

Guan Feng gave a few more instructions and then hung up the phone.

Head to the monitoring room.

Wang Xun was reviewing the surveillance footage when he caught sight of Guan Feng and said, "Captain, you've come at the right time! Look at this balloon. It broke off from the girl's hand and slowly floated to this corner. Judging from the scene in the morgue, this is the ventilation vent, and the other end is the air outlet. In other words, the suspect probably knew this and knew that as long as the balloon was in this room, it would slowly float to this camera."

Guan Feng nodded and said, "Your reasoning is good. Was there any movement in between?"

Wang Xun shook his head and said, "From beginning to end, it lasted until yesterday morning. It never left the camera's view, although there were a few slight shakings in between."

As they spoke, they captured a moment and played a video clip.

In the video, the balloon sways slightly before returning to its original position.

Guan Feng frowned and said, "The airflow in the morgue is constant and the temperature is low, so it's impossible for this to happen suddenly. It must be because someone opened the door, causing airflow turbulence."

Wang Xun said, "That's what I was thinking too, but the sound is too faint. I couldn't hear it clearly even when I used my headset to amplify it."

Upon hearing this, Guan Feng put on his headset and activated the bone conduction function, gradually amplifying the sound.

In the quiet environment, you could almost hear the whirring of the air conditioner. Then, a slight creak came from the door. Although it was faint, the bone conduction technology picked it up perfectly, making it sound like someone had opened the door from the outside.

Guan Feng looked up at the time marker.

3 PM the day before yesterday!

He looked at Wang Xun and asked, "How many more times do you think there are?"

Wang Xun said, "There have been three such instances, namely..." He then directly retrieved the relevant surveillance videos.

Guan Feng listened carefully to each segment, and after a moment he determined that one of them was probably a coincidence, perhaps caused by the balloon shrinking and shifting. The other two were accompanied by the sound of a door opening.

He quickly switched the camera to the elevator entrance.

Synchronize and adjust the time!

One minute later.

The elevator screen appears.

Guan Feng pointed to the footage on the monitor and said, "This movement of the balloon should have been caused by this cleaning staff member. Wang Xun, contact the logistics department and find this cleaning staff member."

Wang Xun said, "Okay, I'll contact them right away." He walked to the side and made a phone call.

A moment later, the cleaning manager arrived.

Cleaning manager Zhang glanced at the surveillance footage and said, "This seems to be Old Yang?"

Guan Feng asked, "Does Lao Yang usually clean the morgue?"

Cleaning manager Zhang said, "That's right! Most people don't want to go to the morgue. Old Yang's family is relatively poor, so he took on this job in order to earn an extra three or five hundred yuan. He goes once a week, right? Let me check if it's the day we have to clean the morgue."

As he spoke, he took out his phone and retrieved the log records.

A moment later, he found the record and handed it to Guan Feng, saying, "It was the day before yesterday! Look, there's a record here."

Guan Feng glanced at it and nodded, but he didn't let the doubt go easily. He said, "We still need to ask this old Yang to cooperate with our investigation, make a statement and record his fingerprints. But Manager Zhang, you should make it clear to him that we are just conducting a routine inquiry, so don't scare him."

Cleaning manager Zhang said, "Okay, I'll notify them right away."

Guan Feng then instructed Li Xiangdong and Huang Lili to take a statement from the cleaning lady.

He then continued to look at the video surveillance.

There was a second one!

This observation finally revealed the problem.

He clearly heard the sound of the door opening through bone conduction, but the elevator surveillance footage showed that no one went to the basement level in the five minutes before and after the other person appeared.

Guan Feng frowned, worried that the time was too short, so he extended the timeline to ten minutes, twenty minutes, and finally even half an hour...

The result was the same as before.

Guan Feng's expression changed.

He put his headset back on to make sure he heard the door open.

He said to Wang Xun, "There was the sound of a door opening, but no one entered through the elevator. The other party is very likely the real suspect!"

Wang Xun put on his headset and asked, "Captain, are you sure there was a door opening sound? I didn't hear anything."
