A woman in Thailand developed such a severe gambling addiction that she resorted to poisoning her own friends to avoid paying back borrowed money. Known as AM, she was a 26-year-old who became obsessed with online casinos, winning at first but soon losing everything. Desperate for funds, she asked a friend for a $3,000 loan, which she immediately gambled away.
When her friend started asking for repayment, AM decided to eliminate the problem rather than admit her losses. She researched cyanide online, acquired it, and secretly poisoned her friend’s food or drink. Within minutes, her friend collapsed and died. Since cyanide poisoning can be difficult to detect, authorities assumed the death was due to natural causes. AM not only escaped suspicion but also stole her friend’s belongings before fleeing.
She moved on with her life and eventually married Weetune, a local police officer. For a while, she seemed to be living comfortably, but her gambling addiction resurfaced. Once again, she borrowed money from multiple friends, lost it all, and found herself in the same predicament. Instead of stopping, she turned to murder again, systematically poisoning anyone who demanded repayment. Over the years, she killed friends using cyanide-laced drinks, food, and even diet pills. Each time, she stole cash, jewelry, and valuables, using the money to continue gambling.
Her crimes escalated as she grew more confident. She managed to poison a police captain, a friend at a market, and even someone while they were out shopping for vegetables. She killed ten friends, and no one suspected a thing. Encouraged by her continued success, she kept going. At one point, she poisoned a friend at a restaurant by offering her cough medicine laced with cyanide. Though the friend collapsed, she survived but was unable to connect the dots.
As AM’s crimes continued, her husband Weetune discovered what she was doing. Instead of reporting her, he decided to help. He became her accomplice, even serving as her getaway driver after one of the murders. With his support, she poisoned more people, including her ex-boyfriend and another police officer.
However, her luck ran out when she invited a new friend, Coy, on a trip to take part in a Buddhist protection ritual. As part of the ritual, they purchased a bag of live fish to release into the river for good luck. While at the pier, AM poisoned Coy, who collapsed on the spot. AM stole her purse and fled the scene, but this time, she had made a mistake.
Coy’s mother refused to believe that her daughter had died of natural causes. She pushed the police to conduct a full investigation. An autopsy revealed traces of cyanide, raising suspicions. When police questioned AM, she denied everything, including being at the pier. However, surveillance footage from that day showed her walking with Coy, carrying the bag of fish.
With undeniable evidence against her, authorities arrested AM. After further investigations, they discovered she had killed 14 people over ten years. She was found guilty in court and sentenced to death. Meanwhile, her husband Weetune, despite his involvement, received a much lighter sentence of one year and four months in prison.
This case remains one of the most shocking crime stories in Thailand, highlighting the extreme lengths to which a gambling addiction can drive a person.
