Chapter 115 – Result – Part 23

Chapter 115 – Result – Part 23

Kim Taehyun, who had been silent for a moment, spoke.

-What is it you want to try?

And at the National Forensic Service, no less.

“I want to look around.”

The National Forensic Service had various departments.

Broadly, forensic genetics, forensic toxicology, forensic chemistry, forensic safety, digital forensics, and so on.

Woojin wanted to see them with his own eyes.

Science continues to advance.

He thought he might be able to gather information he didn’t know from there.

If that happened, it would greatly help with cognitive inference, such as profiling.

Learning was a lifelong endeavor, Ira thought.

Woojin always kept that in mind and was well aware of it.

Everything he wanted to try and all his new experiences fell into that category.

He was also curious about the thoughts of the people working at the National Forensic Service.

And there was something else he wanted to try most of all.

How could a lie detector pick up his brain waves?

It wasn’t just his brain.

He was also curious about what the psychology major who owned the gym would think of him.

-You want to look around, right?

“Yes.”

There was nothing special about the National Forensic Service knowing his identity.

He had already manipulated it to be so, and his identity had to be revealed.

Since he had provided the cause, the result had to follow.

Since he had created the space between the cause and the result of causality, it was a natural progression for a physics theory to be derived.

Since he had set things in motion according to his plan, he just needed to act normally for the result to occur.

Of course, criminals hope for this logic to break, so they flee or hide.

“When can we meet for Mask?”

-When are you free?

“I can go right now, Ira.”

-Hmm…

Woojin’s voice, which had burrowed into Kim Taehyun’s ear, sounded like he wanted to go now.

-Where are you? I’ll go there right now.

“I’ll send you the address by message.”

-Okay.

As Woojin finished the call, Park Inhyeok, who had been drinking water and observing Woojin, asked.

“Does the Police know too?”

Their casual conversation made it seem like they were quite close.

The fact that he had a connection with the Police was not a big deal.

What was important was that Woojin, who had incredible observation skills, knew.

Park Inhyeok threw out a remark as a joke.

“You don’t happen to know the Prosecutor too, do you? Hahaha!”

“I do.”

Park Inhyeok blinked his eyes.

Seriously…

This was the first time he’d met someone who kept revealing new layers like this.

“As I said before, can I order one more pasta?”

His unexpected and quirky way of speaking was also new.

“……Yes, of course, of course.”

And so, Woojin deliciously ate the pasta he ordered.

Park Inhyeok discovered another new side of Woojin.

He didn’t answer well when spoken to while eating.

He savored and swallowed the food in his mouth before finally speaking.

It could have been considered table manners, but he couldn’t help but strongly feel it was the former.

Soon, Woojin finished his pasta and wiped his mouth, saying,

“Thank you for bringing me to this great restaurant. The car isn’t ordinary, so I don’t think it suits me. I’ll just appreciate the thought.”

Park Inhyeok smiled awkwardly and asked again, just like before.

“Are you really sure there’s nothing you need?”

“Yes. Nothing. I think I should get going.”

Just then, the entrance door chimed open, and Kim Taehyun walked in.

“I have somewhere to go.”

Park Inhyeok gave a bitter smile.

“Oh dear… I didn’t waste your time, did I?”

“No. I’m sorry to leave first.”

Park Inhyeok waved his hand.

He didn’t want someone who was like a savior to him to apologize.

Woojin shook his hand, got up from his seat, and approached Kim Taehyun.

“Detective Kim, this place is a great restaurant. You should come with Detective Choi sometime.”

“I’m always eating gukbap with him. And I don’t want to come to a place like this with a guy.”

***

Kim Taehyun’s car was heading towards the National Forensic Service.

He had felt really bad that the National Forensic Service seemed to be bothering Woojin, but now that Woojin was curious and coming along, he felt much lighter.

He had received a lot from Woojin.

So,

“Woojin, where do you want to look around?”

“I want to look around everywhere.”

“Okay. Your older brother here is also friends with the National Forensic Service people, you know.”

Kim Taehyun was really making connections far and wide to catch the criminal.

“A profiler came to the police station the other day, you know? Do you know what they said?”

“I don’t know.”

“They asked how we catch a criminal before forensics even gets involved. They said they were curious. So I told them. A detective’s intuition! They didn’t believe me…”

Woojin, who had been listening to Kim Taehyun, opened his mouth as if to respond.

“Then try telling them this.”

At a red light, Kim Taehyun stopped the car and looked at Woojin.

“Assuming a violent crime has occurred, there are 20 people on the suspect list: 12 men and 8 women. Let’s assume Detective Kim Taehyun’s probabilistic perspective that the criminal is a man is A. In this assumption, if there is no additional evidence, you divide the number of male suspects by the total number of suspects…”

Mathematical formulas began to flow from Woojin’s mouth.

“It’s 0.6. Conversely, if we assume the criminal is a woman, it’s 0.4. But if additional evidence is found and a new incident B occurs…”

“Additional evidence?”

“Yes, long hair found in incident B, the new incident. If we assume there are 10 people with long hair among those on the suspect list, a subset is formed. The occurrence of incident B narrows down the suspects from 20 to 10. If we calculate the probability reliability for these 10 suspects, it’s 0.5.”

Outside the window, a child could be seen toddling along, holding their mother’s hand.

The child could become anything, but also nothing.

However, looking at the righteous path where the mother smiles while looking at the child, and though unheard, observing the mother’s mouth movements as she speaks, one can infer that the world the child will experience will be very positive.

Woojin opened his mouth again.

“At this time, the joint probability is the probability that A and B occur simultaneously, so…”

Kim Taehyun, who was driving, stared blankly ahead.

At first, he almost understood, but the deeper Woojin’s words got, the harder it was to comprehend.

Instead of saying he couldn’t understand, Kim Taehyun threw out a different meaning.

“Woojin, you mean all this time you weren’t just catching criminals by looking with your eyes, but by doing all these calculations?”

Woojin nodded slightly.

“Yes. The skewed angles or positions of ordinary objects are also important. If you look at ordinary things in an extraordinary way, they reveal the truth.”

“Woojin, I’m just asking, just in case, okay?”

“Yes. Go ahead.”

“You don’t see things or anything when you touch objects, do you? What’s that called? Psycho… what is it?”

“Psychometry?”

“Oh! Right! Psychometry! You don’t see things like that, do you?”

“My eye structure is the same as ordinary people, so I can’t see such things.”

Kim Taehyun wanted to say, ‘Other things aren’t ordinary…’, but he couldn’t utter it aloud.

Because Woojin was a younger sibling who always pursued ordinary things.

“I didn’t know you, Woojin, were even calculating.”

“Detective Kim might be too. It’s just that the method is different. Detective Kim is good at intuition, aren’t you? I think that when you dedicate yourself to one task and become proficient, intuition gets closer to the essence of things.”

Kim Taehyun scratched his head.

He used to say he had good intuition, but in reality, the probability was significantly low. No, it was gradually increasing lately.

Why?

Because he was also undergoing changes after meeting Woojin.

“Gosh… My younger sibling speaks so beautifully. Hahahaha!”

It felt good to hear Woojin say that.

***

The car Woojin and Kim Taehyun were driving was able to reach its destination.

Upon entering the entrance, a forcefully engraved inscription on a large stone immediately caught their eye.

Woojin muttered as he looked at it.

“The power of science that reveals the truth…”

The National Forensic Service was a place even ordinary people were curious about.

After all, it was a place where the crystallization of science gathered.

Soon after parking the car in the underground parking lot, Kim Taehyun and Woojin approached the elevator.

Kim Taehyun said,

“I haven’t told them you’re here yet, Woojin. There’s no need to reveal your identity right away. You said you wanted to look around, right? Where do you want to go first?”

Kim Taehyun felt like rolling up his sleeves and helping Woojin with anything he wanted to try.

“Could I take a lie detector test?”

“Huh? A lie detector?”

Kim Taehyun, who had asked with a puzzled look, chuckled.

“So you want to try it?”

“Yes.”

“I’m close with that person, you know. But I’m not sure if they’re in. Just a moment.”

Kim Taehyun immediately brought his cellphone to his ear.

The other person answered the Gold Room phone.

“Researcher Kim Hyeonja. Loyalty! Have you eaten?”

It was Researcher Kim Hyeonja, a lie detection expert.

-Oh dear. Detective Kim, aren’t we talking too often?

“It’s nothing else, but you know that unidentified DNA? I went through a lot of trouble to bring his younger brother here, and he said he wants to take a prosecutor’s test. He’s saved me and the researcher a few tasks, so I want to let him try what he wants.”

Immediately, a curious voice was heard.

-Oh… he’s finally arrived. I have time now, so it’s fine. I’ve wanted to see him too.

It was pure curiosity.

Before the National Forensic Service could identify and apprehend the criminal, this person was identified and apprehended first, then visited the National Forensic Service. It was impossible not to want to see his face.

“I’ll be right up.”

After finishing the call, Kim Taehyun shrugged and said,

“How about that? Your big brother is this kind of person. Straight to a free pass.”

Woojin gave a thumbs up.

“I always thought Detective Kim was an amazing person.”

“I wish I could hear that from someone else.”

If he had heard such words from someone else, he would have felt his ego swell, but hearing them from Woojin didn’t evoke much emotion.

They then used the elevator, walked down the hallway, and arrived at the office where Kim Hyeonja was.

When Kim Taehyun knocked, a voice came from inside.

“Come in.”

Kim Taehyun entered first, and Woojin, who followed him, subtly glanced left and right, then up and down.

He was assessing the office’s layout and contents.

“Welcome.”

As Kim Hyeonja shook hands with Kim Taehyun, his gaze fixed on Woojin.

He had vaguely estimated him to be in his 40s to 50s, but he was much younger than expected, wasn’t he?

His eyes scrutinized various parts of Woojin.

Kim Hyeonja threw out appropriate gestures and words, trying not to let Woojin catch his observant gaze.

Woojin found such detailed observation intriguing.

Kim Hyeonja didn’t think his gaze had been detected, but in Woojin’s perception, his gestures, eye movements, and expressions were being interpreted in his mind.

Conversely, Kim Hyeonja didn’t notice Woojin’s gaze.

“Nice to meet you. I’m Researcher Kim Hyeonja.”

“Hello. I’m Shin Woojin.”

How would Researcher Kim Hyeonja, a psychology major and lie detection expert, perceive him?

It was something that couldn’t help but pique his curiosity, even metacognitively, as he could learn something new about himself.
