I Can Hear a Serial Killer's Voice in My Head

But it's not just his work history that catches our attention. Oh is also registered as a disabled person on the government database, a fact that lines up with my theory about his missing thumb and the clumsy nature of the body disposal.

As we dig deeper into Oh's background, we uncover a disturbing pattern of behavior. Multiple arrests for assault and theft, a string of failed relationships and broken homes... it paints a picture of a man on the edge, a ticking time bomb just waiting to go off.

But it's not until we pay a visit to Oh's workplace that the final piece of the puzzle falls into place. There, sitting in a corner of the factory floor, is an industrial refrigerator. The same make and model that left its telltale mark on Soo-yeon's body.

We question Oh's manager, a harried-looking man with a wary look in his eyes. He confirms that Oh has been employed at the factory for several years, but drops a bombshell that stops us in our tracks.

"He hasn't shown up for work in over a week," the manager says, his voice tinged with a mix of concern and frustration. "No call, no notice... just vanished into thin air."

Oh is on the run, a desperate man with nothing left to lose.

We mobilize quickly, putting out an all-points bulletin and coordinating with local law enforcement to canvas the area. We tap our informants and lean on our contacts, shaking every tree and overturning every rock in our search for the killer.

Drawing on my earlier insights about Oh's likely hideout, we focus our efforts on the seedy underbelly of the city - the low-rent hotels and flophouses where a man like Oh might seek shelter.

We split into teams, each one assigned a different section of the city to canvas. We show Oh's picture to desk clerks and managers, flashing our badges and making it clear that we mean business.

At first, the search seems fruitless. We hit one dead end after another, each lead fizzling out like a damp firecracker. But we press on, driven by our shared determination to bring Oh to justice.

And then, just as we're about to call it a night, we catch a break. A desk clerk at a run-down motel on the outskirts of town recognizes Oh's face. Says he checked in a few days ago, paid in cash, and hasn't been seen since.

We move quickly, securing a warrant and assembling a tactical team. We approach the motel room with caution, our weapons drawn and our hearts pounding with the thrill of the hunt.

At first, there's no response to our knocks and shouts. But then, just as we're about to break down the door, we hear a sound from inside. A muffled cry, a thump, the unmistakable sounds of a struggle.

We burst into the room, our flashlights cutting through the gloom. And there, cowering in the corner, is Oh Jae-sung. His face is gaunt and his eyes are wild with fear, but there's no mistaking the monster who took Soo-yeon's life.

He tries to run, of course. They always do. But we're ready for him, our bodies slamming into his with the full force of the law. We wrestle him to the ground, cuffing his hands behind his back as we read him his rights.

As I stand over Oh's prone form, my chest heaving with exertion and adrenaline, I feel a sense of grim satisfaction wash over me. We did it. We found the monster who had eluded us for so long, the man who had brought such unimaginable pain and suffering to Soo-yeon's family.

But even as the rest of the team celebrates our victory, I find myself slipping back into Oh's mind one last time. I try to imagine what he must be feeling in this moment, the crushing weight of his guilt and shame, the sickening realization that his twisted desires have finally caught up with him.

And then, just as quickly as it came, the moment passes. I shake myself out of my reverie, turning to face my team with a weary but triumphant smile.

We have done our job, fulfilled our sacred duty to the people we serve. And though the road ahead may be long and the scars of this case may linger, we can take solace in the knowledge that justice has been served.

***

The atmosphere in the pub is electric, the air thick with the heady scent of victory and camaraderie. The team has gathered to celebrate our triumph, to toast the successful resolution of the Oh Jae-sung case and the justice we've brought to Soo-yeon's family.

I sit at the bar, nursing a beer and watching as my colleagues laugh and chatter around me. Inspector Kim is there, his usually stern face softened by a hint of a smile. He catches my eye and raises his glass in a silent salute, a gesture of acknowledgment that feels like a hard-won victory in itself.

But even as I bask in the warmth of the moment, I can't help but notice the subtle undercurrents of tension that still linger in the room. Some of the team members, the ones who have been with the unit the longest, still regard me with a hint of skepticism, their eyes narrowing as they take in my presence.

I try not to let it bother me, focusing instead on the sense of pride and accomplishment that swells in my chest. But just as I'm about to excuse myself and head home, I feel a friendly hand clap me on the shoulder.

It's Inspector Han Joon-yong, his face split by a wide, easy grin. "Park!" he exclaims, his voice booming over the din of the pub. "You were incredible on this case. Your insights, your instincts... they were the key to cracking it wide open."

I feel a flush of pleasure at his words, a sense of validation that warms me from the inside out. "Thanks, Inspector Han," I say, my voice gruff with emotion. "I was just doing my job, same as everyone else."

Han shakes his head, his eyes twinkling with mischief. "Nonsense," he says, waving away my modesty. "You've got a gift, Park. A real talent for this kind of work."

We chat for a while, swapping stories and laughing at each other's jokes. And then, almost as an afterthought, Han asks about my family.

I hesitate for a moment, unsure of how much to reveal. But there's something about Han's easy, open manner that puts me at ease. "It's just me and my grandmother," I say, my voice soft with affection. "She runs a small restaurant in our neighborhood, been cooking up home-made Korean food for decades."

Han's eyes light up at the mention of food, his face splitting into a grin. "No kidding?" he says, his voice filled with excitement. "I love that kind of stuff. The real deal, you know? None of that fancy, modern fusion crap."

I can't help but laugh at his enthusiasm, feeling a sense of warmth and connection that I hadn't expected. "Yeah, my grandmother's cooking is the real deal, all right," I say, my chest swelling with pride. "She's been feeding our neighborhood for as long as I can remember."

Han leans in closer, his eyes sparkling with mischief. "You know what? We should go there sometime. You and me. Sample some of that famous home-cooking for ourselves."

I feel a flicker of hesitation, a sense of unease at the thought of mixing my personal and professional lives. But there's something about Han's enthusiasm, his genuine interest in my family and my background, that makes it hard to say no.

"I don't know," I say, my voice hesitant. "My grandmother's place... it's not exactly a cop hangout."

But Han is already waving away my concerns, his mind made up. "Nonsense," he says, his voice filled with determination. "We're a team, Park. And teams stick together, on and off the job."

And so, before I know it, we've made plans to visit my grandmother's restaurant the very next day. Han is practically bouncing with excitement, his eyes gleaming with anticipation.

As we say our goodbyes and head our separate ways, I can't help but feel a sense of warmth and belonging that I hadn't expected. Sure, there are still those on the team who doubt me, who question my place among them.

But with Han's gesture, with his easy friendship and genuine interest in my life, I feel like maybe, just maybe, I've found my place after all.

And as I make my way home through the neon-lit streets of Seoul, I can't help but smile at the thought of what tomorrow will bring... of the new bonds and the new adventures that await.
