Police in Campobasso are carrying out a new interrogation in the ricin poisoning investigation tied to Pietracatella. Officers of the Mobile Squad questioned a laboratory technician, the husband of a longtime acquaintance of Gianni Di Vita, the man linked to the case. The technician works at the Istituto Agrario in Riccia, Campobasso, a school that was among the sites searched in the weeks before. The investigation concerns the deaths of two women, Antonella Di Ielsi and Sara Di Vita, mother and daughter, who died after being poisoned with ricin in December 2025. The probe continues against unknown suspects for double premeditated murder. While the police work on further statements from people informed of the facts, the next round of interrogations is scheduled for the coming week. At the same time, five doctors remain under investigation for manslaughter by negligence in connection with the deaths. The investigation remains ongoing, with the latest interrogation now under way in Campobasso and further hearings planned next week.
