Overview
- Forensic medical exams have confirmed Antonella Di Ielsi and her daughter Sara died from acute ricin poisoning, with sources reporting toxin amounts about 140 times the minimum lethal dose, a finding investigators say undercuts the accidental‑ingestion theory.
- The Procura of Larino has ordered an 'ispezione informatica' to copy and examine more than 70 computers and notebooks at the Istituto Agrario di Riccia on October 13 to look for web searches, downloads or files containing terms such as "ricina," "veleno" and related chemical keywords.
- Police have already searched the home and offices of Gianni Di Vita; he voluntarily handed over a USB drive and two computers and investigators say he is not currently under formal investigation.
- Investigators are focusing physical searches on the school’s chemistry lab and the area near the greenhouse because the castor plant grows locally and those spaces could hold traces of sourcing or preparation of ricin, but the exact vehicle and timing of exposure remain undetermined.
- The case remains an open double homicide file classified as 'duplice omicidio volontario aggravato dal mezzo venefico' with no accused persons; prosecutors say digital forensics could provide the next key leads and potentially identify who researched or procured the toxin.
