Chapter 64

"Early this morning, the rain stopped for a while. Someone saw a person get injured and collapse next to the flower bed. They called the police, and when the police arrived, a woman claimed that someone had slashed her husband and then fled."

"These are the photos preserved from the scene, and these are the blood samples."

"What I am teaching you today is how to reconstruct a case without even going to the scene."

"In other words, crime scene reconstruction."

Several trainees instantly perked up; this was only briefly mentioned in their textbooks.

When the school instructors taught this course, they made it very clear: learning the theory is one thing, but doing it is another.

"First, the fundamental thing you need to understand is the concept of why a person is called a human."

Instantly, viewers in the livestream started taking notes.

Old Liu is really bringing out his true skills.

Here, Qu Yiling said: "Humans have stress responses. Excluding long-term training, most people's stress responses are similar."

Old Liu said: "That's a clever answer, but only half right."

Cheng Ruofei said: "Humans possess intelligence and will try to conceal things."

Chen Ti said: "Human emotions and desires lead to extreme actions."

Xu Xintong said: "Humans always try to make up for the mistakes they've made."

Xiang Qinqin said: "Everyone is the same after they die."

Old Liu looked at Xiang Qinqin and said: "Surprisingly, this is the answer I am most satisfied with. But if you combine it with Qu Yiling's answer, then you have the complete answer."

"A person's stress response before death is also a branch of forensic science called human behavioral science, which is a sub-branch of forensic anthropology."

"As for after a person dies, that involves pathology, pharmacology, and related autopsies."

"Remember, for a forensic scientist, the autopsy is just the most primitive and basic step. Beyond the autopsy, there are many more cases."

With the photos placed there, Old Liu pointed to a few stools and said: "That stool is the flower bed. I am now going to teach you how to reconstruct the scene."

Taking out the photos, Old Liu walked to a position slightly in front of the flower bed.

"The blood splattered, so based on the bloodstain patterns, the person should have been at this position."

"But the blood on the ground didn't splatter wildly, which means this person was moving backward slowly."

"Then, they collapsed next to the flower bed and subsequently crushed these flowers."

"The blood appeared here."

Everyone was stunned, staring at Old Liu.

"You like deduction, don't you? Then let me give you a forensic deduction: this person knew the man, was familiar with him, and discovered him in time. Who is this person?"

Everyone said in unison: "It's the wife."

In the observation room, the audience was completely dumbfounded.

The audience was totally bewildered.

"Wait, hold on, did they just catch the killer? Isn't that too fast?"

"Damn, didn't this person call the police? Right, the wife called the police saying someone slashed her husband."

"Something's not right. Someone called the police, but the wife didn't; she took her husband to the hospital."

"In the middle of the night, the husband goes out, the wife takes him to the hospital—damn, was there a third party involved?"

Several trainees also wanted to ask if he was meeting a mistress, but unfortunately, Old Liu's words echoed in their ears: "We forensic scientists deduce the person, not the event."

In the observation room, Qin Ming said: "It really is Old Liu. I guess Li Tian's deductions made him unhappy, so he brought out his signature skills."

Teacher He asked: "Are these all real?"

"Yes, they are all real. This is a scene simulation. It has been done before, just as a rough draft. Recall the case Qu Yiling and Xiang Qinqin simulated a while ago regarding the hikers—didn't Qu Yiling sit on the ground?"

Everyone remembered and clapped.

"This is what's called a simulation, or what everyone is familiar with as a crime victim simulation, which belongs to the category of crime scene reconstruction."

"Also, Chen Fan's deduction of a person using just one hand is actually a form of crime scene reconstruction. However, I suspect Chen Fan is the only one in the country who can pull that off."

"Is it very difficult?"

Jing Tian asked curiously. Qin Ming replied: "This is no longer a matter of difficulty; it has already exceeded the scope of human understanding."

Everyone looked at Chen Fan, who was quietly looking at his phone and chuckling.

Everyone was speechless.

Is this guy a non-human, a genius?

"What's with those looks? Hey, I saw the contempt in your eyes. Damn, did you do that on purpose?"

Teacher He felt exhausted and said: "Forget it, let's get back to the case. So, was it the wife?"

Qin Ming pointed to the screen.

Old Liu said: "Li Tian's handling was faster. To be precise, it wasn't Li Tian; the investigating police officers locked onto the suspect immediately."

"Uh, how did they lock onto her?"

"Through a series of questions. The police asked the man, 'What did the person you saw look like?'"

"The woman gestured."

"The police continued, 'What weapon was this person holding?'"

"The woman said it was a kitchen knife."

"The police kept pressing, 'What kind of kitchen knife? How long was it?'"

The woman started to stammer.

Shortly after, the police detained her.

They found nearby surveillance footage. It was simple: the man went downstairs to meet a mistress, the wife couldn't take it, grabbed a knife, and slashed him. The man must have tried to block it, which is why his hand was cut off.

After Old Liu finished, everyone was shocked. Damn, it can be done like that?

Looking at everyone, Old Liu continued: "That's why many cases can actually be solved on the spot. As for the suspenseful cases you see in TV shows and movies, they are just intentionally convoluted."

Everyone sighed with emotion.

"Remember, what you see with your own eyes isn't necessarily the truth. Communication is the core. In fact, the moment you start suspecting the man is meeting a mistress, you've already decided whether he is guilty or not."

"In reality, he wasn't meeting a mistress, but a colleague. The man had told his wife he was going downstairs to pick up something a colleague had delivered."

"The other party had previously received help from this woman at work, and the man and that lady's husband were very familiar with each other."

The young people were completely confused.

Old Liu said: "So, who was wrong? Is it the principle of 'a gentleman does not stand under a dangerous wall,' or is the woman just suspicious? There are arguments for both sides. I cannot judge what the third party's intentions were, nor will I say what kind of woman she is."

"But remember, communication is the first priority."

The five people kept their heads down, not speaking.

Old Liu said: "This happened early this morning. You know, this woman has a mother and a child who need someone to take care of them, and this man has had his hand cut off. So, tell me, what will happen if this woman is arrested?"

The continuous questions not only left the five trainees bewildered, but even left the audience feeling confused.

Just then, Old Liu said helplessly: "I said, hearing isn't necessarily believing. Is what I said necessarily true?"

The group looked at Old Liu, suddenly not understanding.

"I'm teasing you. These were the exact words from the police station."

"Look at you all, I was just joking."

Damn.

Old Liu, you'd better stop joking, seriously.

This joke of yours is enough to scare people to death.

Chen Fan, however, was very calm and said: "This is simple. If she's arrested, she's arrested. There's no such thing as 'forgiveness' for slashing someone. You guys watch too much toxic chicken soup. Criminal cases require public prosecution. Do you think saying 'the family forgives' is enough? Those are just standards for the judge to weigh, not a requirement."

Everyone thought of a previous case where a father-in-law slashed his son-in-law to death, and the son-in-law's wife forgave her father.

But no one knew what happened after that case.

Teacher He said: "That child and that mother are the ones having the hardest time, right?"

Everyone looked at Chen Fan. Chen Fan said: "Don't look at me. I won't sympathize. I think sympathy is meaningless. There are many people worse off than them. Instead of caring about others, you'd better think about yourselves. Sorry, my capacity for empathy might be a bit low."

But everyone seemed to understand.

"But what I want to say is, good job on the arrest."

Damn, your dramatic pause is really something.

Here, Old Liu let the trainees try to simulate other cases, picked up his hot water cup, and drank happily.

Li Tian strolled over.

Looking at Old Liu, he said: "You're up very early today."
