It was just another Friday morning in Madisonville. The kind of humid June day where the air feels heavy before the sun even peaks. At 9:12 a.m., a call came in about a guy with a gun acting "belligerent" near Whetsel Avenue. Sonny Kim, a police officer who had seen it all over a 27-year career, was the first to roll up. He didn't know he was driving into a trap. He didn't know the man who called 911 was the same man waiting to pull the trigger.
Honestly, the story of Sonny Kim isn't just about that one terrible morning in 2015. It’s about a guy who moved from Seoul to Chicago and then found his soul in Cincinnati. He wasn't just a badge. He was a sensei, a father of three boys, and a man who once jumped off a bridge into the Ohio River to save someone. People still talk about him in the Queen City like he’s coming back for the next shift.
The Ambush Nobody Expected
The details of what happened on June 19, 2015, are still gut-wrenching. The suspect, a 21-year-old named Trepierre Hummons, had basically decided on "suicide by cop." He’d sent texts. He’d posted on Facebook. Then he called the police on himself.
When Sonny Kim arrived, Hummons' mother was actually standing there. She told Kim her son didn't have a weapon. Trusting that info, Kim stepped out with his Taser instead of his gun. It was a split-second decision rooted in de-escalation, the kind of thing we beg for today. Hummons stepped from behind his mother and fired.
The investigation later revealed something haunting. It was "horrible luck," as Prosecutor Joe Deters put it. Out of the shots fired, one found the tiny, impossible gap in Kim's body armor. It hit between the ribs, veered, and severed an artery. It was a one-in-a-million shot that proved fatal.

Even while wounded, Kim fought. He struggled with the suspect over his service weapon. A probation officer and another officer, Tom Sandmann, arrived shortly after. A gunfight erupted in the middle of the street. Sandmann eventually stopped the threat, but the damage was done.
A Life Defined by More Than a Uniform
You can't really understand Sonny Kim if you only look at his "End of Watch" date. He was a 27-year veteran. That's a lifetime in police work. Most guys are looking for the exit by year twenty, but Kim was still out there, Badge 396 pinned to his chest.
- The Sensei: He ran the Japanese Karate-Do dojo in Symmes Township.
- The Immigrant: Born in Seoul, South Korea (1966), he moved to the states in '73.
- The Family Man: He left behind his wife, Jessica, and three sons—Tim, Joshua, and Jacob.
His students at the dojo didn't just learn how to kick. They learned a mantra he made them recite: Seek perfection of character. Be faithful. Endeavor. Respect others. Refrain from violent behavior. It’s kinda ironic, isn't it? A man who preached against violence died by it while trying to keep the peace.
Why Sonny Kim Still Matters in 2026
It’s been over a decade, but you’ll still see blue lights and "Kim Strong" stickers around Cincinnati. Why? Because he represented a version of policing that people actually respect. He wasn't some "warrior" looking for a fight; he was a neighbor who happened to be a black belt.

In 2020, they renamed East Hyde Park Commons to Officer Sonny Kim Park. It’s right next to the District 2 headquarters where he worked. It’s not just a plaque; it’s a place where kids play and people walk their dogs—the exact kind of community he spent 27 years trying to build.
There’s also the annual Sonny Kim Fallen Officers Memorial Ride. Hundreds of motorcycles roar through the city every June. It’s loud, it’s visceral, and it raises money for the families of other fallen first responders. It keeps the conversation going about the mental health of suspects (Hummons' "suicide by cop" intent) and the vulnerability of the people we send to help.
Things Most People Get Wrong
People often think Kim was killed in a random shootout. He wasn't. He was lured.
Another misconception is that his vest failed. It didn't "fail" in the sense of being defective. The ballistics report showed the bullet hit at such a precise, lateral angle that no standard vest at the time could have caught it. It was a tragedy of centimeters.

Lessons From a Legacy
If you're looking for what to take away from the life of Sonny Kim, it’s basically this: character isn't what you do when the cameras are on, it’s the 21 commendations he earned over three decades when nobody was looking. He was the "consummate policeman" because he actually cared about the people on his beat, even the ones who were "belligerent."
What you can do to honor this kind of legacy:
- Support Local Training: Look into organizations like the Cincinnati Police Federal Credit Union, which often manages memorial funds for fallen officers.
- Practice De-escalation: Whether you're in law enforcement or just dealing with a heated argument at work, remember Kim's mantra: Refrain from violent behavior.
- Visit the Memorial: If you're in Cincinnati, go to Officer Sonny Kim Park. Read the signs. Understand that every badge represents a person with a family and a hobby—like karate—who just wants to get home.
The reality is that police work is inherently dangerous, but it’s the way Sonny Kim lived—with "tunnel vision" for service since he was a kid at the University of Cincinnati—that makes his story stick. He wasn't a superhero. He was a man who chose to be there. And that's probably more important.
