A 64 year old woman from Kamphaeng Phet province, who believes her daughter is the 15th cyanide-poisoning victim of Sararat Rangsiwuthaporn, also known as the Thai cyanide serial killer, met with Crime Suppression Division (CSD) police investigators yesterday, stated a police source.

The woman responded to a letter from the police and reported to the deputy national police chief’s team of investigators at the Police Club on Vibhavadi Rangsit Road. She provided information about her daughter Montathip, 37 years old, who died in Bangkok seven years ago. The woman reportedly told the police that she personally suspected Sararat to be responsible for her daughter’s death, despite not having any evidence to back this belief. She expressed her gratitude to the deputy national police chief for accepting her daughter’s case for investigation, hoping that Montathip would receive justice.

CSD deputy commander Pol Col Anek Taosuparp revealed that a meeting took place yesterday, Monday, May 1, to discuss the cases involving Sararat, stating that the investigation was approximately 80% complete. Regarding the 33 year old victim, Siriporn Khanwong, Pol. Col. Anek reported that no evidence had been discovered to implicate anyone other than Sararat. He added that the testimonies from five witnesses were valuable for further investigation, and thus far, no evidence pointed to a senior police officer, who was Sararat’s former husband.

Rapee Chamnanrua, a man requested by Siriporn’s relatives to assist them in probing her suspicious death, also met with the police investigators at the Police Club on Monday. Rapee shared his intentions to travel to Kanchanaburi province to obtain significant evidence related to a bank account of one of the alleged victims. Despite the owner’s death, the account remained active, with hundreds of thousands of baht circulating. He confirmed that he would provide the account documentation for the police investigators to examine.

The commander of the Metropolitan Police Bureau’s training centre, Pol. Maj. Gen. Namkiat Teerarojanapong, tasked with compiling cyanide-poisoning cases, stated that investigators yesterday sought arrest warrants from the Criminal Court for Sararat in four more cases.

These four cases included:

  • The death of a man, Surat Toraphap, in Kanchanaburi on December 6, 2020;
  • The death of a woman, Chantharat, in Cha-am district, Phetchaburi;
  • The death of a woman, Kanika Tuladecharat, in Photharam district, Ratchaburi province, on January 6, 2021;
  • The case of a woman, Kantima, who survived a murder attempt in Muang district, Kanchanaburi province, in September 2022.

As the investigation continues, authorities aim to bring justice for these victims and uncover any further information related to the cyanide-poisoning murders. The pursuit of additional arrest warrants demonstrates the investigators’ determination to hold the alleged perpetrator accountable for these devastating and tragic deaths.
