Hong Kong film: Who says being an undercover cop has no future?!

"But there's something fishy about this."

"The crimes all occurred in the early morning or even the middle of the night."

“There was even one family that kept a dog.”

"Dogs are very protective of their owners; once they choose an owner, they will be loyal for life."

"If the attack comes from the outside, the dog will definitely bark and alert the police."

"But it's not here."

"So this tells us something... the murderer was the victim's guest."

Huang Bingyao, Xu Weijie, and Li Jie were all stunned.

guest?!

Such a vicious guest?!

Wang Tiancheng pointed to another file

“You have also checked the surveillance footage of this victim family.”

"This further corroborates the point."

"The elevator camera was incomplete, but it clearly showed a stranger following the victim home."

"Even if they didn't get a direct shot at his face,"

"I am also certain that the murderer was the victim's guest."

"Then, a clear clue has emerged."

"The murderer was someone the victim knew!"

"Even if they are unfamiliar with the victims, they will not be afraid or wary!"

……

Wang Tiancheng's expression was very serious.

"Determining how the murderer entered is the key to solving the case."

"In these three cases of family annihilation, we can clearly determine that the murderer was invited into the victim's home."

"Then, a series of inferences can be generated!"

"The methods used in these three cases are the same."

"It can be confirmed as a series of cases."

"The murderer must have had some kind of connection with the three families."

"Most likely, they are photographers, mail carriers, repairmen, or healthcare workers."

"Because Inspector Xu's preliminary investigation had already ruled out the possibility that the three victims were friends."

"This inference arises naturally."

Xu Weijie looked at Wang Tiancheng with admiration.

"That's right!"

"The murderer was a photographer from all three companies."

"Our investigation revealed that two of the three families had attended a friend's wedding together."

"The murderer was the photographer who took pictures at the wedding banquet."

"And the other family photo was also taken by the murderer."

Wang Tiancheng nodded in thanks.

"Let's get back to the case."

"What makes me so confident in determining the killer's physical characteristics?"

"I did not stand by while the murderer was committing the crime."

"But I'm sure that's what I described the killer to be like."

Xu Weijie's gaze towards Wang Tiancheng revealed admiration.

“That’s right, Wang Sheng’s profile was completely accurate.”

"It's like witnessing it with my own eyes."

Huang Bingyao urged

"Acheng, tell us about it."

Wang Tiancheng laughed.

"It looks amazing, but it's actually not difficult at all."

"It's like a thin sheet of paper; once you explain it, it's nothing new."

"First of all,"

"This is a case of annihilation of an entire family."

"To kill an entire family spanning three generations without escaping, one must possess excellent physical strength."

"Women's physical strength is clearly insufficient, so only men are suitable."

"Even an old man doesn't have enough strength."

"Only young and middle-aged people can do it."

"The age of the murderer can be naturally deduced as an adult male between twenty-two and thirty-five years old."

"What about the other characteristics?"

"These three families told me."

The three of them were all taken aback.

"How did these three families tell you this? Did they send you a message in a dream?"

Wang Tiancheng shook his head.

No!

"These are the three photos, a family portrait!"

"Three generations live under one roof, and there is even a family with four generations living together."

"The elderly and children are all here."

"If you have elderly people or children at home, what kind of guest would you feel comfortable letting in?"

"Letting people in late at night won't raise any suspicion."

"Most importantly, you don't know this guest at all!"

Huang Bingyao, Xu Weijie, and Li Jie were all taken aback.

Right!

The murderer was clearly a stranger to all three families.

In a family with elderly people and children, why would you feel so comfortable letting him go out?

Wang Tiancheng said calmly

"The killer's appearance was too deceptive; he appeared too harmless."

"First and foremost, it must be people of Asian descent."

"Only Hong Kongers can gain a sense of identity; white people, black people, or other foreigners will definitely not be allowed in."

The three of them nodded in unison.

So, what kind of person is considered harmless in the eyes of Hong Kong people?

"He had a smile on his face, even a hint of humility, a touch of naivety, and a hint of shyness."

"He was exceptionally honest, answering every question thoroughly and without reservation."

"No matter how you look at it, he seems honest, simple, and even a bit timid."

"This is the first impression a murderer gives."

"Only someone like that can make you feel at ease letting people in, even at night."

Huang Bingyao and Li Jie both looked at Xu Weijie.

Xu Weijie looked at Wang Tiancheng as if he were a god.

"That's right, all correct."

"That's exactly what the killer looks like!"

"The officers who went to make the arrest initially suspected they had arrested the wrong person."

Wang Tiancheng shrugged.

"See, profiling is that simple."
