Thai Court Issues Second Death Sentence to Serial Killer Driven by Illegal Online Gambling Debts
SCCG Take — The rulings expose how illegal online gambling can enable extreme financial crimes, reinforcing Thailand’s push for tighter platform enforcement and chemical controls.
Thailand’s criminal court has issued a second death sentence to Sararat Rangsiwuthaporn, known as Am Cyanide. The ruling concerns the fatal poisoning of a creditor in Nakhon Pathom province in December 2020. Prosecutors identified Rangsiwuthaporn as a gambling addict responsible for 14 killings and one attempted poisoning to generate funds.
Sararat Rangsiwuthaporn, 39, mixed potassium cyanide into food served to Darinee Thepthawee, 34. Rangsiwuthaporn had borrowed THB 60,000 (about $1,850) from the victim and persuaded her to join three informal savings schemes promising combined returns of around THB 200,000 ($6,150). The victim was lured to a local market, consumed the laced food, suffered convulsions, muscle rigidity, foaming at the mouth and loss of consciousness. An autopsy at Siriraj Hospital confirmed death by multiple organ failure.
Pattern of Poisonings Across Seven Provinces
Rangsiwuthaporn was arrested in Bangkok on April 25, 2023 after the family of Siriporn Kanwong, 32, raised suspicions over her death on April 14 in Ratchaburi. Siriporn collapsed on the banks of the Mae Klong River following a Buddhist merit-making ritual with Rangsiwuthaporn. Forensic tests found cyanide in her body. Police recovered a bottle of cyanide from Rangsiwuthaporn at the time of arrest.
Investigators connected her to 15 poisonings between 2015 and her 2023 arrest across seven provinces. Fourteen victims died. Most had financial links to Rangsiwuthaporn through loans, car transactions or informal savings schemes. Victims included an ex-boyfriend and three female police officers. The killings prompted heightened scrutiny of toxic chemical controls.
Court records show Rangsiwuthaporn spent THB 78 million (about $2.3 million) over three years gambling on the illegal online platform Fun88, with single-day bets reaching THB 10 million (around $290,000). The latest ruling is the seventh judgment across 15 cases, yielding two death sentences, two life sentences and three acquittals. In related developments, Thailand’s Ministry of Digital Economy and Society blocked almost 14,000 illegal betting websites during the FIFA World Cup as part of a stricter stance on gambling, according to GamblingNews.
