Double fatality sparks murder inquiry in southern Italy
Prosecutors in Italy have launched a homicide investigation after laboratory tests confirmed that a mother and her teenage daughter died from ricin poisoning following a pre-Christmas lunch in the small town of Pietracatella, 260 km south-east of Rome.
The incident
Sara Di Vita, 15, and her mother Antonella Di Ielsi, 50, fell critically ill after sharing a meal at their home on December 23, 2025. Sara's father, Gianni Di Vita-former mayor of Pietracatella-was also hospitalized but later recovered. The couple's eldest daughter was not present during the meal.
Initial misdiagnosis and rapid decline
Physicians initially treated the symptoms as food poisoning, likely caused by contaminated fish or mushrooms, and discharged both patients. However, their condition deteriorated within hours, prompting readmission. Dr. Vincenzo Cuzzone, head of intensive care at Cardarelli Hospital in nearby Campobasso, told Italian media that liver failure set in first, followed by multi-organ collapse "at an unprecedented speed."
Toxicology findings shift investigation
While early reports attributed the deaths to medical negligence-leading to a manslaughter probe against the discharging doctors-new toxicology results from laboratories in Italy and Switzerland revealed the presence of ricin, a lethal toxin derived from castor beans. Authorities have not yet identified any suspects.
About ricin
Ricin is a naturally occurring poison with no known antidote. Ingesting even a minute amount can trigger rapid organ failure and death. Its detection has redirected the inquiry from medical error to potential criminal intent.
Next steps
Prosecutors are now reviewing security footage, witness statements, and meal remnants to trace the source of the poison. The case remains active, with no arrests made as of Wednesday.
