Authorities in Campobasso are advancing the inquiry into the deaths of Antonella Di Ielsi and her daughter, Sara Di Vita, following ricin poisoning in Pietracatella. Investigators are moving beyond primary subjects to interview new individuals and are awaiting crucial scientific results from the Robert Koch Institut in Berlin. These analyses aim to identify the specific food or vector used to administer the toxin and to confirm if other family members, including Gianni Di Vita and the second daughter, Alice, were exposed.

Following a summit between Larino prosecutor Elvira Antonelli and the mobile squad, investigators have reportedly identified a “passionate motive” for the double homicide. The investigation is currently focusing on Gianni Di Vita, the husband and father of the victims, as a potential target of the killer. 

As part of the probe into premeditated murder, Laura Di Vita, the cousin of Gianni Di Vita, was summoned for a four-hour hearing to address potential inconsistencies regarding statements made by Gianni and a female friend. The investigation remains complex as the families of the victims seek justice.
