"Detective Han, I've found the killer in the surveillance footage!"
Upon hearing these words, Han Fei's eyes immediately lit up.
Originally, after searching the surveillance footage for so long without results, Han Fei had almost given up hope of finding any trace of the killer in the videos. He had even started preparing to investigate the victim's social connections to try to identify the perpetrator.
But unexpectedly, good news arrived in an instant.
Wang Dachuan had actually spotted the suspicious janitor in the surveillance footage!
The two quickly walked over to Wang Dachuan's side.
"Look, it's this man!" Wang Dachuan excitedly pointed at a man in the surveillance video that was playing.
The man he was pointing to wasn't wearing a janitor's uniform. Instead, he was dressed in a tracksuit.
This was completely different from the janitor's outfit they had seen in the TV station building's surveillance footage.
At first glance, no one would connect this man in a tracksuit with the janitor who had appeared earlier in the TV station.
Han Fei gave Wang Dachuan a puzzled look.
The latter immediately explained.
"We couldn't find him after searching the footage for so long, probably because he avoided the cameras when changing out of the janitor's uniform. We were also fixated on looking for someone in janitor's clothes in the surveillance videos, so we overlooked some clues. I specifically went back to look at the footage from the TV station, analyzed the killer's gait and overall physique, then reviewed the surveillance videos again. Finally, I found this man. Let me show you a clip to compare, and you'll see..."
Saying this, Wang Dachuan pulled up another piece of surveillance footage from the TV station.
He placed the two videos side by side for comparison, circling the persons of interest in both clips.
Although the two circled individuals in the surveillance videos were dressed differently - one in a janitor's uniform and the other in a tracksuit - upon closer inspection, it became clear that the people highlighted in the two videos had identical physiques and walking gaits.
While there might be many people with similar body types, the chances of them also having the same walking style were slim.
This was clearly the same person wearing different clothes!
"It's definitely the same person," Xu Mo glanced at Han Fei beside him. "He probably wore the janitor's uniform over his tracksuit, then after committing the crime and leaving the TV station, he found a blind spot in the surveillance and took off the outer layer of janitor's clothes."
Han Fei nodded, he had come to the same conclusion.
"No wonder we couldn't find this person in the surveillance footage before. We were focused on looking for someone in janitor's clothes, it would have been a miracle to find him," Han Fei patted Wang Dachuan's shoulder. "Well done!"
Praised by Han Fei, Wang Dachuan scratched his head and immediately returned the compliment.
"Hehe... It's all thanks to your excellent guidance, Detective Han."
"Stop with the flattery. Now that we've confirmed the killer's trail, shouldn't you quickly take a few people to follow the lead and make an arrest?" Han Fei put on a stern face and lightly tapped the back of Wang Dachuan's head.
Although he spoke as if he strongly disliked such flattery, in reality... Han Fei felt quite pleased being complimented.
After all, who could resist being flattered?
Even knowing that the other person was just saying what you want to hear, sucking up to you, it still feels good to hear such words!
Especially since Wang Dachuan had praised Han Fei in front of Xu Mo.
Subtly implying that Han Fei was a great mentor.
Han Fei felt like he had scored some points in front of Xu Mo!
Wang Dachuan, who had just been tapped by Han Fei, grinned and said,
"Right away, I'll gather a few colleagues and go make the arrest!"
It's worth noting that earlier at the TV station, the killer had been wearing a mask and keeping his head down, so the surveillance cameras hadn't captured his face clearly.
But after taking off the janitor's uniform, the killer made no attempt to hide his face, perhaps thinking the police would never find him after he had avoided the cameras and changed clothes.
So his face was captured by the surveillance cameras.
With facial features to go on, identifying him became much easier, and there was no need to keep scrutinizing surveillance footage.
They could simply use Skynet, which would track him precisely wherever he went, as long as he passed by any place with surveillance cameras.
Wang Dachuan had indeed used Skynet to directly locate the killer's position.
From Skynet, they learned that the man had already returned home.
After obtaining the killer's location, Wang Dachuan called on a colleague from his team who he often worked with on missions, as well as Xu Mo. The three of them set out together to make the arrest.
...
Half an hour later.
Garden community.
The police car stopped at the entrance of the community, and the three men got out and walked in.
Building 4, Apartment 1302.
"Knock knock knock." A forceful knocking sound rang out.
The man inside looked through the peephole.
Three strangers were standing outside the door.
Police officers can choose to wear either their uniform or plain clothes while on duty.
Xu Mo and the other two officers participating in this operation were all in plain clothes, so even through the peephole, the killer couldn't tell that the three people standing outside were police officers.
Instead, he assumed they were community workers coming to register some information, or some other kind of visitors.
In any case, he didn't consider the possibility that the three people standing outside his door might be police officers.
He casually opened the door.
"Who are you?"
"Police." Wang Dachuan took out his police badge. "You're Sun Jian, right? We're here to ask you a few questions."
The moment Wang Dachuan showed his police badge, a flash of panic crossed Sun Jian's face, but it quickly disappeared, leaving him looking exceptionally calm and composed.
However, that fleeting expression was caught by Xu Mo.
Xu Mo could almost certainly conclude that this Sun Jian must be involved!
It wasn't because of that momentary panic on Sun Jian's face.
In fact, it's normal to feel panicked and scared when police officers show up at your door saying they want to ask some questions. After all, who wouldn't be nervous when faced with police?
Ordinary people, even those who haven't committed any major crimes, would instinctively feel anxious when encountering police officers.
But to panic and then immediately regain composure - that was highly unusual.
This was clearly an attempt to conceal his panicked emotions!
Xu Mo narrowed his eyes as he sized up this Sun Jian.
He wore glasses, had short hair, and looked clean-cut, giving off a sense of a cultured villain. He was about 1.83 meters tall.
He had opened the door with his left hand, which was still on the doorknob - most likely left-handed.
1.83 meters tall, left-handed - both these points matched the forensic analyst's earlier deductions.
Realizing Xu Mo was looking at him, Sun Jian glanced back at Xu Mo.
Then he smiled and looked at Wang Dachuan.
"Officers, what information do you need from me? I'll cooperate fully."
"It's not convenient to talk here. Please come with us to the police station," Wang Dachuan said, putting away his badge.
"Alright, let me change my shoes."
Saying this, Sun Jian turned to the shoe cabinet by the door, took off his slippers, and put on a new pair of sneakers.
Xu Mo was all too familiar with these shoes.
Weren't these the same type worn by the janitor in the TV station surveillance footage?
They had indeed found the right person.
That janitor was, without a doubt, Sun Jian!
