TL;DR In the late 1980s, a 40-something housewife struggling with cabaret gambling debts poisoned five people, including her creditors and her own family members, using potassium cyanide. Her chilling MO: She handed them poisoned drinks in public places like city buses and bathhouses. When they collapsed, she pretended not to know them, stopped others from helping, and stole their valuables. She was eventually caught when cyanide was found hidden inside a wooden pillar in her bathroom. She became the last female death row inmate to be executed in South Korea on December 30, 1997. When we think of a “serial killer,” we often imagine gruesome crimes in dark alleys or isolated places. But one of the most shocking serial murder cases in South Korean history took place in broad daylight, on city buses and in public bathhouses, at the hands of a very ordinary-looking housewife in her late 40s. Cabaret Gambling Debts and the First Murder Kim Sun-ja was an ordinary mother of three sons, married to a painter. However, she fell deep into a gambling addiction, frequenting cabarets and amassing millions of won in debt (a significant amount in the 1980s, considering an apartment in Seoul cost around 10 to 20 million won). Suffocating under the pressure of her debts, she hatched an unfathomable plan: instead of paying back her creditors, she would kill them and steal their money. In October 1986, she lured a member of her social club to a public bathhouse and handed her a health drink laced with potassium cyanide. When the victim collapsed in severe convulsions, Kim stopped bystanders from helping, lying that her friend “suffers from epilepsy.” After the victim died, Kim stole her diamond ring and necklace. Because the victim had a history of high blood pressure, the death was ruled a heart attack without an autopsy, kicking off Kim’s deadly game. The Devil’s Smile Targeting Her Own Family Her methods grew increasingly audacious. On a city bus, she offered a poisoned cup of adlay tea to a creditor who had lent her 7 million won. When the victim collapsed in agony, Kim coldly stated, “We are not together,” and got off the bus alone after stealing the victim’s cash and jewelry. The most horrifying incidents were her fourth and fifth victims: March 1988: On an intercity bus, knowing her own father was carrying a bag full of cash, she handed him a poisoned health drink. April 1988: On a city bus returning from a children’s park, she gave a poisoned drink to her own younger sister. Even as her flesh and blood were dying right in front of her, she pretended to be a complete stranger, stealing their cash and handbags before fleeing the scene. Caught: The Truth in the Graves and a Wooden Pillar Finally, when her last victim (a distant sister-in-law) died in a cafe under similar circumstances, the bereaved family reported their suspicions to the police. They pointed out that five people close to Kim Sun-ja had suddenly died of “heart attacks” in a short period, and large sums of money had gone missing every single time. Taking an extreme measure, the police obtained a search warrant and exhumed the bodies of four victims from their graves for autopsies. The result? Lethal doses of potassium cyanide were found in all of them. The definitive smoking gun was discovered during a search of Kim’s home. Police found a small lump of cyanide wrapped tightly in newspaper, hidden inside a crack in a wooden pillar of her traditional outhouse. Final Thoughts From the moment of her arrest until her final breath on the gallows in December 1997, Kim maintained her innocence, constantly shouting, “I am falsely accused. I never killed anyone!” This is a chilling case where someone weaponized the trust of her closest friends and family with a simple drink. How far can blind greed and money destroy a person’s humanity? What are your thoughts on this extreme case of criminal psychology? submitted by /u/IngenuityGlittering |
