A prosecutor is on the hunt for the parties who "incited" Tiziana Catone's suicide.
Cantone was found dead in her aunt's home near Naples in September, more than a year after a sex video she filmed spread across social media.
The 31-year-old had sent the clip to some friends, including her ex-boyfriend, to make him jealous.
However, the video and her name soon found their way to the web, where the woman was mocked and abused. The footage has been viewed by almost a million internet users.
In a bid to escape the humiliation, Ms Cantone quit her job, moved to Tuscany and tried to change her name, but her nightmare went on.
