The Thai cyanide serial killer, Sararat “Am” Rangsiwuthaporn, yesterday made a shocking confession to investigating officers that she obtained the poison from her now-dead ex-husband. While Sararat has yet to confess to any murders, she did acknowledge giving cyanide to her late husband, Suttisak “Dae” Poonkwan, as well as one of the victims, Siriporn “Koy” Khanwong.

Police Officer Namkiat Theerarojanapong yesterday visited Sararat at the Central Women’s Correctional Institution in Bangkok for the third round of questioning. The aim was to unravel any remaining uncertainties surrounding the case.

During the interrogation, Sararat requested to meet with the Deputy Commissioner of the Royal Thai Police (RTP), Surachate “Big Joke” Hakparn, and her police ex-husband, Withun “Off” Rangsiwuthaporn.

Both Big Joke and Off met with Sararat yesterday evening and shared the details of their discussion today. Big Joke disclosed that while Sararat had not confessed to the murders of the 14 victims and the attempted murder of a survivor, she did admit to providing cyanide to Koy.

According to Big Joke’s latest update, Off was initially charged with misappropriation, fraud, forgery of documents, and damaging criminal evidence.

Sararat claimed that she obtained the cyanide from another ex-husband named Dae, who also used it in combination with other drugs. Sararat herself is suspected of murdering Dae. She allegedly provided Koy with a plastic bag containing cyanide, instructing her to mix it with other drugs.

Despite Sararat’s confession, Big Joke expressed some doubts and stated that further questioning would be conducted tomorrow, May 17, to delve deeper into the case.

Last week, the RTP summoned and interrogated Sararat’s younger brother, sister-in-law, and a close friend. This action was taken after the sister-in-law delivered a parcel containing Koy’s belongings to one of Sararat’s friends. The three individuals remain under surveillance.

Additionally, Sararat changed her legal representation last week, switching from lawyer Thannicha Ek-suwannawat to Chinnakupt Taiyakorn. However, Chinnakupt announced in a media interview yesterday that he declined to represent Sararat due to the complexities of the case. While the police have gathered compelling evidence, Sararat’s lack of admission of guilt makes mounting a defence challenging.
