Chiara Nava Monia, identified as Gianni Di Vita 's " special friend ," her husband Michele, and a close relative of the man, possibly a cousin. These are the three people currently under investigation in the deaths of Antonella Di Ielsi and her daughter Sara , who died in Pietracatella, in the province of Campobasso, after being poisoned with ricin.
The investigation is also continuing through the analysis of the computer systems of four schools in Molise, where some of the individuals involved in the investigation work or studied. These leads remain to be investigated, while investigators attempt to reconstruct the dynamics of the double homicide and a possible motive.
Investigations into the deaths of women poisoned with ricin: the four schools and the audits of their computer systems.
The investigations primarily concern the agricultural institute in Riccia , where Michele works as a laboratory technician and operates a greenhouse. Also in Riccia is the scientific high school where Monia allegedly taught. The investigations also involve the classical high school in Campobasso , attended by Sara and her older sister Alice, who graduated in July, and the "Silvio Di Lalla" high school in Casacalenda , where a cousin of Gianni Di Vita works as a support teacher.
Investigators are focusing particularly on any digital traces that could help reconstruct the facts. According to reports by Corriere della Sera and Repubblica , an anonymous person allegedly posted questions about ricin on Reddit starting in August 2025, presenting himself as a writer interested in researching for a fictional character. The requests reportedly concerned the substance's characteristics and the possibility of identifying traces after a death . The account apparently remained inactive for a period, but resumed posting after the deaths of the two women.
Investigators are reportedly trying to determine the source of those connections and their possible connection to the schools' computer systems . At this time, however, it is not possible to definitively attribute those searches to any of the individuals involved in the investigation.
The accidental poisoning hypothesis and the first findings
Among the scenarios being examined by investigators, according to journalistic reports, is the possibility that Antonella and Sara were poisoned by mistake and that the substance was initially intended for Gianni Di Vita , the woman's husband and the girl's father. This is an investigative hypothesis that requires further confirmation and cannot be considered a confirmed reconstruction.
The investigations are intertwined with rumors about the couple's private life . According to some reports, Antonella may have considered separating from her husband , partly because of alleged extramarital affairs. It will be up to investigators to determine whether these elements are actually relevant to the motive.
Meanwhile, the investigations at the agricultural institute in Riccia concluded on Monday afternoon. Giovanni Alfonso , an IT consultant appointed by Gianni Di Vita's defense, explained that no computers were taken: investigators apparently acquired data from a centralized server that manages the institute's network connections.
According to the consultant, the IT infrastructure uses an internal firewall that allows connections to be managed through the central system. The server data was therefore acquired for further analysis, without seizing the 71 computers at the school. The investigation is expected to continue at the Riccia scientific high school. The goal is to identify any useful information that could clarify the source of the online searches and determine whether there are any concrete connections to the case.
