Episode 38: They are two different people
“Do you have any plans, Inspector?”
Wi Jun-woo asked as he followed me stealthily.
“What’s the plan? If there’s no one in the office, I’ll just go in and look at the case files and come out.”
“No, there are more than one or two case files. How can you just read them all in one go? It’ll take two or three hours just to read them all.”
“Don’t worry. This genius brain can read everything.”
We walked slowly down the hallway, looking around. As Kisooyoung had hinted, it was lunchtime. Most of the people in the office were heading to the cafeteria.
Our plan is to quickly go into the office when it’s empty and look through the case files on the murder of the doctor of oriental medicine.
Since it’s a case that’s currently being processed, the case file will definitely be on Na Kang-jin’s desk. The problem is that, as Wi Jun-woo said, the volume is enormous.
Police report, suspect statement, witness statement, autopsy report, CCTV, scene data and photos. I don’t know for sure, but if you stack them on a desk, it’ll probably be over 30cm high.
So I understand Wei Jun-woo’s worries. He has to check and leave quickly before the office owners come back. He can’t read or copy all those files.
But that’s just a normal person’s story. There’s no problem with this genius Do Hyeon-gwang.
[It’s not because he’s a genius, it’s because of me. Aliota, the AI specialized in law!]
‘Yeah. It’s because of you. Other people think I’m a genius. Hahaha.’
When we arrived at the 4th floor where Na Kang-jin’s office was, everyone seemed to have already headed to the cafeteria, so the hallway was empty. We cautiously opened the door to Na Kang-jin’s office and went in.
There was no one in the office, only empty desks. It seemed like Na Kang-jin, the investigators, and the staff had all gone to lunch. Case files were piled up like a mountain on and around Na Kang-jin’s desk.
I said to Wi Jun-woo, who followed me in.
“I’ll look at the files here, so you go outside and keep an eye out to see if anyone comes.”
“Are you okay alone? But you’ll be able to see more with four eyes.”
“Don’t worry about that. If anyone comes outside, just give me a signal.”
“Yes. How do I signal it?”
“Well, anything. Let’s make it a bird song.”
“yes.”
Wi Jun-woo nodded and went out the door. In fact, if someone came, it would be a big problem. Even if I gave a signal in advance with the sound of birds, how could I escape from here? It was the fourth floor, and I couldn’t go out the window.
The best thing to do is to check quickly and leave before anyone else comes. I quickly started looking through the case files.
Fortunately, the file on the murder case of the Korean doctor was still lying on Na Kang-jin’s desk. I picked up the file and flipped through the pages one by one.
‘Are you saving it?’
[Yes, you can skip ahead a little.]
Aliotta was saving the documents I was handing over as if taking pictures. Naturally, it was much faster than me reading them.
Even so, the amount of data was so vast that it seemed like it would take a long time. I flipped through the case files, my hair flying.
‘Oh, I think it’s almost done. Let’s just look at this and leave.’
[yes.]
‘Okay. Let’s go now.’
It was then that a strange sound was suddenly heard from the left end of the hallway outside the office.
“Oi oi oi oi oi ii~”
As I was about to leave the office, I stopped dead in my tracks.
‘No way. Is that a bird’s sound?’
[That can’t be true. As far as I know, there is no bird on this earth that cries like that.]
‘If the new name is ‘Wei Jun-woo’, then it might be possible.’
It was a strange and absurd sound that I couldn’t even imagine being the sound of a bird, but I held my breath, leaned against the office door, and listened outside. It could be Wei Jun-woo sending me a signal.
‘Do you have any clairvoyant abilities?’
[Do you think so? If I look closely, it seems like Hyungwang thinks I have some kind of magic wand?]
‘It’s because I’m frustrated.’
[You can’t see it, but you can hear it.]
‘Oh, right.’
As I looked toward the direction of the strange bird sounds beyond the closed door, I heard a ticking sound as if the frequency was being adjusted, and soon I heard Wi Jun-woo’s voice.
– Oi oi oi oi oi ii~
– Chief Wi Jun-woo? What are you doing?
– Ah. That… … Something’s stuck in my throat. Ahem. Big. By the way, where are you going, Hyun-joo?
– Let’s go to the office.
I think it’s Kim Hyun-joo, the office worker at Na Kang-jin’s office. Can I sneak out while talking to Kim Hyun-joo?
I opened the office door quietly. I peeked out and saw Kim Hyun-joo talking to Wi Jun-woo at the left end of the hallway. Fortunately, Kim Hyun-joo had her back to me.
If I can just hold out like that for 10 seconds, I think I can get out.
Just go to the right of the hallway and turn the corner.
I opened the door slowly and took a cautious step outside. Wi Jun-woo, who saw me opening the door and coming out, asked Kim Hyun-joo a question to get her attention. But.
“Aren’t you going to eat lunch?”
“I’m on a diet these days. I only drink coffee. Okay.”
Kim Hyun-joo, holding the coffee in her hand, was about to turn around.
Eww.
I had one foot out, so I had no choice but to quickly come back into the office.
‘Ah, Wi Jun-woo. Can’t you last those 10 seconds? What should I do?’
[There is no place to hide in the office. You have to get out of the office before people come.]
‘So, how do I get out?’
While I was taking out my anger on the poor Aliota, an unexpected voice was heard from outside the door.
– You’re here, Chief.
– Uh. Soyoung?
– What should I do? I don’t think we can have lunch together.
– Yes? Excuse me, lunch?
‘Isn’t that Kisoyoung?’
[you’re right.]
‘But why Kisoyoung? Wait, you and Wi Junwoo used to eat together?’
My heart was pounding at the gossip, and I was about to put my ear against the door, when Aliotta clicked her tongue. I don’t know if you can click your tongue on the topic of artificial intelligence, but that’s what happened anyway.
[Hyun-kwang. Right now, Ki-so-young is buying us some time. We should hurry up and get out.]
‘Huh? Was it like that?’
I opened the door again and looked. Kisoyoung was talking to Wijunwoo, whose face was red.
As expected, Kim Hyun-joo, who was walking to this office, stopped in the middle of the hallway, turned her back to me, and stared at the two of them.
[Now! I have to go now!]
‘okay!’
I closed the door quietly and walked quietly in the opposite direction of Wi Jun-woo, making sure not to make a sound. As I walked like that, I naturally had no choice but to move slowly. That was why I could clearly hear Ki So-young’s voice coming from behind me.
“I’m too busy today, so I don’t think I can do it. I’ll be free tomorrow evening. What do you think, Manager?”
“I, I have time tomorrow evening.”
‘Why is Wi Jun-woo shaking like that? Do you really like Ki So-young?’
[Oh. Focus on walking. Don’t make any noise. Be careful.]
Finally, I reached the corner, hid my body against the corner wall, and looked at the other side of the hallway with only my eyes peeking out. Unlike Ki So-young, who looked calm, Wi Jun-woo was stiff with a red face, and Kim Hyun-joo was fiddling with her phone in her hand as if she was trying to send a KakaoTalk message to someone.
Ki So-young glanced at me and saw that I had disappeared around the corner, then spoke to Wi Jun-woo.
“Then I will ask the inspector if he has time tomorrow.”
“Yes? The inspector?”
Wi Jun-woo asked in a harsh voice.
“We decided to have a team dinner together. Let’s do it together tomorrow night.”
“Oh, I see. We were planning to have a team dinner. Haha.”
As Wi Jun-woo, who was visibly disappointed, let out an awkward laugh, Kim Hyun-joo, who was looking at them, said.
“It was a team dinner. I also thought Soyoung was on a date.”
As she spoke, Kim Hyun-joo repeatedly tapped her phone with her thumb. It seemed as if she was erasing what she was writing.
“Right. Why would Soyoung date the Chief Wi? Oh, I didn’t mean it in a bad way, Chief. Well, both of you, take care.”
Kim Hyun-joo turned around and headed toward the office, and I quickly hid behind the corner.
Wi Jun-woo, that must have been a good ending.
* * *
After returning to my room, I asked Aliota.
‘Did you save all the case files earlier?’
[Yes. Would you like to print it out for easier viewing?]
‘Wouldn’t that be nice?’
Aliotta sent the file about the murder of the doctor of oriental medicine that she had saved earlier to the printer in the office, and the printer was spitting out paper after paper while making a whirring sound.
Because there was so much to read, it seemed like it would take two or three hours just to read it all.
At that moment, the door opened and Wei Jun-woo came in with a haggard face. I approached Wei Jun-woo and placed my hands on both of his shoulders.
“Bio appreciating your efforts in rescuing me from the office.”
“How long must I remain a life-long believer by your side, Inspector?”
“Hmm. How long? Always? Forever? Forever and ever? Forever ever?”
“Ego. It’s my fate.”
Wi Jun-woo, who was shaking his head, handed me a plastic bag.
“What is it?”
“A sandwich. It’s hard to go to the cafeteria right now anyway. Let’s eat it for lunch.”
“Okay. As expected, the manager has good sense!”
We took out our sandwiches and looked through the files on the murder case of the doctor of oriental medicine.
“Wow. How did you get all this out in such a short time? That’s amazing.”
“I don’t want to brag, but I’m a bit of a genius.”
“I guess so. It’s just unlucky though.”
“Okay, enough chit-chat. Let’s look at the case files. It’s going to take quite some time to look through them all.”
“yes.”
As the two of them were going through the case files separately, Wi Jun-woo said while looking at the information about Yoon Ki-seok.
“It seems like you, Prosecutor, are certain that the culprit is Yoon Ki-seok.”
“Yoon Ki-seok. The person in charge of cleaning and miscellaneous tasks at . Hmm, his IQ is a bit low.”
“You must think that Yoon Ki-seok is the culprit because there is some solid evidence, right?”
I took out a piece of paper with a picture of a knife attached to it.
“This is the weapon used in the crime. Let’s see where it is. No blood was found. Yoon Ki-seok’s fingerprints were found.”
“If there was a fingerprint, wouldn’t it be really obvious?”
Instead of answering, I read what was written.
“Two DNAs were detected, one is unidentified and the other is Yoon Ki-seok’s. As the chief said, fingerprints and DNA were found, so it will be disadvantageous for Yoon Ki-seok.”
[Hyun-kwang. The fingerprints are a bit strange.]
‘What’s strange? What’s wrong with it?’
According to the documents, there were three fingerprints on the handle of the knife. The thumb, index finger, and middle finger. It was a bit strange that the fingerprints were found on the knife when it had been cleaned so that no bloodstains were found. As Na Kang-jin said, criminals often make mistakes.
[If you look at the data I have entered, if there is a fingerprint on a weapon such as a knife or an axe, if it is a complete fingerprint, most of the time the fingerprint is facing upwards.]
‘direction?’
[But on this knife, the fingerprints are facing downwards.]
‘What does that mean?’
[Hyun-kwang should do that. I just pointed out the strange points based on the data that was previously entered. The analysis is Hyun-kwang’s job.]
Who would call it a tin can? Although it pretends to be artificial intelligence, at best it is nothing more than a collection of vast amounts of data.
Is it this genius’ job to analyze that data?
The direction of the fingerprint. A different direction means that the direction of the hand is different.
“What other evidence was there besides the knife?”
“They say a jacket with the victim’s blood on it was found at Yoon Ki-seok’s house. Oh, I think it’s this photo.”
The photo that Wi Jun-woo showed was a scene from CCTV. A man with bushy hair and slightly hunched shoulders was walking in an awkward pose.
He was wearing faded old jeans, a white T-shirt, and sneakers with the heels creased. He was holding something rolled up in his hand, and at first glance, he could see a red stain.
“I guess that’s the jacket you’re holding in your hand right now.”
“Here’s a separate photo of the jacket. Maybe he rolled it up and carried it around because he was afraid that other people would notice the blood.”
I looked closely at the photo of the jacket alone. The bloodstains on the yellow jacket, which looked like it was made of a pretty high-quality fabric, were clearly visible.
‘I guess I couldn’t just wear that and go.’
“Here’s another CCTV photo, sir. This one was probably taken in front of the Oriental Medicine Clinic.”
“That’s right. I see you took a picture with a Korean doctor.”
This was a CCTV photo taken in front of the Oriental medicine clinic building before the criminal lured them into the alley. Since this was before the incident, the criminal was wearing a yellow jacket here. However, while the Oriental medicine doctor was facing forward, the criminal had his back to the camera, so his face could not be seen.
Furthermore, the criminal was wearing a dark-colored hoodie under a yellow jacket, and the hoodie’s hood was pulled over, making it impossible to tell the criminal’s hairstyle or hair type.
At that moment, Aliotta blurted out a word.
[They’re different, Hyungwang. The Yoon Ki-seok we saw in the picture earlier and the man in the yellow jacket in this screen have different physicalities.]
‘The physical is different? Isn’t it just the screen ratio that’s different? Because they’re different cameras.’
[No. There is a 100% chance that they are different people.]
