Death Loans: Thailand's Cyanide Murders

They trusted her. Then, a series of mysterious deaths raised a chilling question: what, if anything, connected them?

At the centre of the case is Sararat Rangsiwuthaporn, widely known as “Aem Cyanide”, whom police came to suspect in a number of deaths across Thailand. What began as an investigation into individual cases soon widened as police uncovered possible connections between them. Cyanide became a key focus, while questions emerged over money and the ‘sharing circle’ relationships which Aem had with some who died.

With rare access to those closest to the case, the series goes inside an investigation that gripped Thailand and left families searching for answers. As new details come to light, it traces how suspicion fell on Aem and examines the evidence that turned a series of mysterious deaths into one of Thailand’s most extraordinary criminal investigations.
