The prison life of Go Yu-jeong, the woman convicted of brutally murdering her ex-husband, has been spotlighted in a recent episode of TV Chosun’s Modern People History Mr. Lee, aired on July 1. The episode also featured insights from former detective Lee Dae-woo, who recounted details of South Korea’s most notorious “bodyless murder case.”
In 2020, the Jeju District Court sentenced Go Yu-jeong to life imprisonment for the murder and subsequent mutilation and concealment of her ex-husband’s body. The case caused nationwide outrage, particularly because the body was never recovered.

Shocking new details have emerged about her conduct behind bars at Cheongju Women’s Correctional Facility. According to a former inmate, Go Yu-jeong was initially ostracized by fellow prisoners and has developed a reputation for poor hygiene. “She rarely washes up. Since she won’t go outside for hot showers, she’s left with cold water, which she avoids due to the cold,” the former inmate explained.
The report also describes how Go Yu-jeong reacted aggressively when faced with bullying. “One inmate said she stood outside Go Yu-jeong’s cell for a month, cursing her every day. Eventually, Go Yu-jeong snapped and cursed back, which shocked everyone in the cell,” the former inmate revealed.
Go Yu-jeong’s chilling demeanor was also addressed by profiler experts during the program. They estimate her psychopathy score to be in the mid-30s, far exceeding the threshold for being labeled a high-level psychopath. “She showed no remorse. Instead of acknowledging wrongdoing, she expressed confusion over the situation,” one expert said.

Go Yu-jeong’s crime was especially disturbing because her young son was allegedly present during the murder of her ex-husband. Surveillance footage and search history uncovered during the investigation, including keywords like “how to cook pork bone soup” and “Jeju sea trash,” along with traces of zolpidem found in her ex-husband’s blood, helped secure her conviction despite the absence of a body.
Go Yu-jeong’s chilling case remains one of South Korea’s darkest criminal episodes, and the latest revelations about her behavior in prison continue to fuel public horror and fascination.
