Serial Killer Yoo Young-chul, Part 1: Monstrous Origins
Yoo Young-chul remains Korea's most notorious serial killer. His crimes shocked the nation, changed policing practices, and left scars that remain visible more than two decades later.
In the first installment of our four-part series, we examine Yoo's troubled upbringing, his experiences growing up in an urbanizing Seoul, his repeated encounters with the criminal justice system, and the worldview that eventually led him to murder.
We also follow his first killing spree in late 2003, when he targeted wealthy elderly victims living in standalone homes near churches throughout Seoul.
Our research draws heavily from Korean-language reporting, academic studies, and contemporary sources. Along the way, we uncover how Yoo's resentment, obsessions, and distorted moral code evolved into one of the darkest chapters in modern Korean criminal history.
