Jenjira “Pui” Ployangunsri was 23, in her fifth year of medical school in Bangkok, and expected to be back for a meeting at seven o’clock. She never made it back.
In this episode of Shadows of Siam, we examine the 1998 murder of Jenjira Ployangunsri, the changing confessions of fellow medical student Serm Sakhonrat, the forensic evidence that broke his story apart, and the DNA work that helped make this one of Thailand’s landmark criminal investigations.
This is not a story about sensational details. It is about Pui: a daughter, granddaughter, friend, and doctor-in-training whose life was reduced too often to the crime committed against her. We follow the investigation from her disappearance through the Bang Pakong River evidence, Dr. Porntip Rojanasunan’s forensic work, the court finding of premeditated murder, the life sentence, Serm’s release after about 13 years and 9 months, and the later debate over rehabilitation, punishment, and his attempt to enter the legal profession.
Content warning: This episode discusses intimate-partner violence, murder, and the postmortem treatment of human remains. Graphic detail is limited, but listener discretion is advised.
