The video continues to play.
Apart from these two people, the only other time someone went in or out of the bathroom was around 3 or 4 a.m.
However, those people were clearly drowsy, and considering the circumstances at the time, it was unlikely that they had committed the crime. But Guan Feng wanted Huang Lili to take photos and record them for further backup and investigation.
Next.
He then turned the screen forward.
It played from 11 o'clock to 9 o'clock.
Around 9 o'clock.
This is the time when the last person discovered that the faucet handle was still there.
The video played in sync.
The number of people going to the toilet gradually increased.
Someone goes in and out of the toilet almost every one or two minutes.
This also aligns with men's daily routines.
Given the large number of people, Guan Feng does not believe that there is a possibility of a deliberately set "trap" during this time period.
But we must not let our guard down!
Record all relevant personnel.
A moment later.
The time display shows 10 o'clock.
There are fewer people at this time; by 11 o'clock, only about 10 people were using the restroom.
Guan Feng focused his attention on these individuals.
Perhaps the other party was well hidden, because Guan Feng did not find any clues.
But the more this happened, the more Guan Feng felt he was beginning to grasp the truth of the case.
However, there are too few clues available.
That wasn't enough for him to unravel the mystery.
He said to Huang Lili, "Make a copy of all these videos."
Huang Lili asked, "Captain, is anyone among these people a suspect?"
Guan Feng shook his head, staring at the screen, and said, "It's hard to say. The murderer may be hiding among them, but we can't pinpoint him. We can only wait for further clues."
Huang Lili said, "Then I'll copy it first."
As they were talking.
Ring ring!
Guan Feng's phone rang.
He took out his phone and saw that it was Chen Xuewen calling. He immediately answered and asked, "Old Chen, did you have a lead? What? You collected some information? Good! Great! I understand. Okay, I'll take some people back right away."
After hanging up the phone, he said to Huang Lili, "Copy the video. Captain Chen has found an important clue. He extracted half a fingerprint from the faucet. We need to compare them one by one, especially checking everyone who enters the bathroom after 9 o'clock."
Huang Lili immediately replied, "Okay, I'll copy it right away."
Guan Feng glanced around and, considering the murder case, realized that Huang Lili might not be safe alone. He said to Liu Shengguo, "You stay here and cooperate. We'll go over together after Lili finishes copying."
Liu Shengguo touched the pistol at his waist and solemnly said, "I understand!"
Guan Feng nodded, glanced at the security guards in the distance, and returned to the dormitory building.
Five minutes later.
Guan Feng lifted the police tape and went into the restroom.
"Old Chen, what's going on?"
Chen Xuewen pointed to the glittery fingerprint in his hand and said, "The fingerprint was inserted halfway into the victim's lower jaw, and the friction caused it to wear down, but fortunately it wasn't deep. We extracted the fingerprint from the lower half of the faucet, which is this small half!"
Guan Feng took the fingerprint, scanned it against the light, and asked, "Can you tell the difference?"
Chen Xuewen nodded and said, "It's not a big problem! It's just half a fingerprint, which makes comparison difficult. Plus, there's the probability of coincidence, so it probably can't be considered solid evidence."
Guan Feng said, "Let's compare them first, and I'll figure out the rest."
Chen Xuewen asked, "Is there a suspect?"
Guan Feng shook his head and said, "Not yet! But we have a rough list of people. Liu Yang went in and out of the toilet around 11 p.m. last night. It was adjusted to around 9 p.m., and he was the last person to see the faucet."
"A total of 43 people entered and exited the restroom during this time period. Let's compare them one by one to see if there is any overlap. If there is no overlap, then this case is more complicated than we thought."
Chen Xuewen clicked his tongue and said, "Forty-three people? That's a bit of a heavy workload."
Guan Feng said, "I will have my team cooperate, along with officers from the branch office, to try to complete the comparison within an hour."
Chen Xuewen immediately said, "That's good! Thank you, Captain Guan."
Guan Feng waved his hand and said, "I should be the one who believes in you!"
Next.
Guan Feng immediately summoned the head of the human resources department.
The head of the Human Resources Department is surnamed Zhang!
He was a middle-aged man in his fifties.
She looked well-maintained and exchanged polite greetings with Guan Feng, indicating her willingness to cooperate.
Guan Feng handed over the personnel information and said, "I need to conduct a fingerprint investigation on these forty-three people, and I also need Director Zhang to arrange for someone to cooperate."
Director Zhang immediately replied, "I'll arrange it right away."
soon.
All the residents on this floor of the dormitory were summoned.
Through mutual identification, the relevant personnel were all identified.
However, there were only forty-two people.
Li Xiangdong had already finished giving his statement and was pulled over to cooperate with the investigation. He said, "That's not right. There are forty-two people listed here instead of forty-three. Does anyone know the last one?"
Everyone looked at each other, and no one spoke.
Guan Feng glanced at the crowd, about to speak, when he saw a figure in the middle of the crowd muttering, "Why is Old Yang using the restroom on the second floor? Isn't he on the third floor?"
Although the muttering was very soft, Guan Feng's lip movements were still discernible.
He knew what was going on, and looked at Director Zhang, asking, "Old Zhang, is this person hard to find?"
Director Zhang explained, "We usually arrange one dormitory per production line and one workshop per floor. People on different floors may not be familiar with each other, but that's okay. I'll go back and compare the information, and I'll definitely be able to find out who the other person is!"
Guan Feng looked at everyone and reminded them, "Did you hear that? If any of you know them, don't try to hide it, because you can't hide it anyway!"
No one in the room spoke.
Guan Feng picked up the person who had been talking to himself and said, "You! Yes, it's you. Could you please come over here? We have a few questions for you."
