Summary
Lee Eunhae (李恩海), who is serving a life sentence in South Korea over the so-called valley murder case, was found to have made game cards from A4 paper and used registered-mail stamps bought through a prison cooperative for gambling inside detention. She was punished with nine days of solitary confinement over the incident, which has drawn fresh scrutiny to a broader pattern of stamp-based gambling in South Korean prisons and detention centres
Key Points
- South Korean reports said Lee Eunhae, identified as a main offender in the “valley murder case”, was caught organizing gambling while in custody
- She allegedly drew playing cards by hand on A4 paper and used stamps available through the prison cooperative as gambling currency
- The disciplinary penalty was nine days in solitary confinement after the activity was discovered inside the detention facility
- An investigation cited by local media found more than 1,000 inmates were caught over suspected “stamp gambling” in the past four years
- Registered-mail stamps with a face value of 3,830 won, about HK$22.4, were described as one of the most popular betting units
Why It Matters
For Hong Kong readers, the case offers a rare look at how ordinary low-value items can become an informal prison currency when cash is unavailable. It also raises questions about prison supervision, inmate labour exchanges and whether controls on commissary-style purchases are sufficient to curb underground gambling networks
