Autopsy reveals lethal ricin levels in Pietracatella mother-daughter deaths
Toxicology tests in the deaths of Antonella Di Ielsi and Sara Di Vita revealed ricin levels 140 times the minimum lethal dose as Italian investigators focus on homicide leads.
Forensic findings point away from accidental poisoning
Autopsy and toxicology tests conducted on Antonella Di Ielsi and her 15-year-old daughter Sara Di Vita revealed poison concentrations equal to 140 times the minimum lethal dose. The findings, released as part of the ongoing investigation into the December 2025 deaths in Pietracatella, have significantly diminished the hypothesis of accidental ricin ingestion. Chief Prosecutor of Larino Elvira Antonelli stated that while investigators continue to evaluate every angle, accidental consumption remains the least plausible explanation.
We are collecting all relevant elements on all possible leads. That of accident is, frankly, the most improbable.
Medical examiner Benedetta Pia De Luca, who performed the autopsies, and Carlo Locatelli, director of the Maugeri Poison Control Center in Pavia, clarified that medical tests verify ricin toxicity but cannot establish whether ingestion occurred by accident or through deliberate third-party action.

Police searches and voluntary submissions by Gianni Di Vita
In late September, police officers from the Squadra Mobile and the Central Operations Service carried out coordinated searches targeting Gianni Di Vita, the husband of Antonella and father of Sara. Authorities searched his current residence in Pietracatella, his local studio on via Risorgimento, and his primary accounting office on via D'Amato in Campobasso, where he had worked alongside his late wife. Di Vita remains unindicted, with investigators confirming that he is not formally registered as a suspect.
Following the search in Campobasso, Di Vita accompanied police to the provincial headquarters on via Tiberio to sign official search records before leaving around noon. Later that day, the former mayor returned voluntarily to provide investigators with a USB storage drive, telling reporters outside that he was completely calm. Shortly after 18:00 on the same evening, Di Vita made a third visit to the police station to hand over two personal computers for digital forensic analysis.
Family reaction and commentary from legal figures
The developments prompted public reactions from family members, including Salvatore Di Ielsi, the father of Antonella and grandfather of Sara. Speaking in television interviews on Rai Uno and Canale 5, Di Ielsi referred to past marital friction between the couple and questioned whether Di Vita was involved or manipulated.
Why did it happen? Maybe over something shameful. For a woman, must it come to this?
Former Mani Pulite prosecutor Antonio Di Pietro, who resides at a farm in Montenero di Bisaccia near the area, cautioned against jumping to premature conclusions regarding intentional murder. Di Pietro pointed out that police have questioned approximately 200 individuals as persons with knowledge of the facts without establishing deliberate intent.
Making suppositions in the absence of evidence, of trial outcomes, is useless; it is premature to say it was intentional homicide.
Di Pietro noted that proving willful intent remains difficult and suggested that investigators must still explore whether the poison was introduced through involuntary manslaughter or an untainted gift delivered without criminal knowledge.
