A Thai court has handed down a second death sentence to Sararat Rangsiwutthikul, a woman dubbed ‘Aem Cyanide,’ for the murder of Darinee Thepthawee. This latest conviction adds to a series of legal judgments against Sararat, who is accused of poisoning at least 15 people across seven provinces between 2015 and 2023, with only one victim surviving.
Details of Darinee Thepthawee’s Murder
Prosecutors presented evidence to the court indicating that Sararat, 39, administered potassium cyanide to Darinee Thepthawee, 34, by mixing it into food. Medical examiners at Siriraj Hospital confirmed through an autopsy that the potent poison caused the failure of Darinee’s vital organs, including her heart, lungs, and liver, ultimately leading to her death. The autopsy report detailed how the cyanide induced organ failure, resulting in the fatal outcome.
The victim’s elder sister testified that Sararat had contacted Darinee via text message on December 12, 2020, proposing a meal of Hainanese chicken rice at the Samphran market the following day and extending an invitation. The court found that Sararat was in the company of Darinee during the critical period when the cyanide would have taken effect on December 13, 2020.
Following her departure from Sararat, Darinee returned home. She informed her husband that she was feeling unwell, subsequently experiencing a seizure characterized by profuse salivation before losing consciousness. Her condition rapidly deteriorated, leading to her death.
Motive: Debt and Financial Ruin
Evidence presented in court revealed that Sararat had known Darinee since 2014 and had frequently visited her home. A significant factor in the prosecution’s case was Sararat’s substantial debt to Darinee, amounting to 60,000 baht. Additionally, Darinee had been persuaded by Sararat to invest in three separate chit funds, a form of informal savings group. Investigations indicated that Sararat was unable to repay Darinee due to overwhelming debts owed to numerous other creditors.
The court concluded that Sararat orchestrated Darinee’s murder as a means to absolve herself of this debt. This financial motive appears to be a recurring theme in the series of poisonings attributed to her.
The Wider Pattern of Poisonings
Sararat’s alleged killing spree sent shockwaves through the nation, prompting increased scrutiny of regulations governing the sale and control of toxic chemicals, particularly cyanide. Investigators have pieced together a disturbing pattern: between 2015 and 2023, 15 individuals are believed to have been poisoned by Sararat in incidents spanning seven different provinces. The vast majority of these cases resulted in fatalities.
According to investigators, financial gain, specifically the elimination of debts owed to victims, was the primary motivator behind these poisonings. A chilling commonality across these cases is that the victims had reportedly been in Sararat’s company just hours before their untimely deaths, suggesting a calculated and opportunistic approach.
Discovery of the Serial Killings
The extent of Sararat’s alleged crimes began to surface following the death of Siriporn Khanwong in Ratchaburi on April 14, 2023. Sararat and Siriporn were known to be friends. Siriporn collapsed and died near the Mae Klong River, a location the two women had visited for a merit-making ceremony involving the release of fish. Cyanide was subsequently detected in Siriporn’s body.
Disturbingly, reports indicate that Sararat did not attempt to assist Siriporn when she fell ill. Instead, she allegedly fled the scene, taking with her the victim’s personal belongings and cash. This act suggested a callous disregard for the victim’s life and a focus on theft.
Arrest and Previous Legal Proceedings
Sararat, who was married to a high-ranking police officer, was apprehended on April 25, 2023. At the time of her arrest, she was reportedly four months pregnant. She later suffered a miscarriage while in police custody.
Prior to this second death sentence, the courts had already delivered judgments in six other murder cases involving Sararat. These previous rulings included one death sentence and two life imprisonment sentences. She was acquitted in three other cases, with the most recent acquittal occurring on August 4.
Ongoing Legal Battle
Prosecutors have formally charged Sararat in a total of 15 cases. These charges comprise 14 counts of murder and one count of attempted murder, reflecting the gravity and scale of the alleged offenses. The legal proceedings are ongoing, with further trials expected to address the remaining charges.
The case continues to be a significant legal and social issue in Thailand, highlighting concerns about the accessibility of dangerous substances and the need for robust legal frameworks to prosecute serial offenders. The court’s decisions underscore the severity of the crimes and the pursuit of justice for the victims and their families.
