Mirella Gregori disappeared in Italy during the summer of 1983, just weeks before the disappearance of Emanuela Orlandi, a case which became one of Italy’s most infamous unsolved crimes. Orlandi’s disappearance garnered significant attention, overshadowing the investigation into Gregori’s vanishing. Both cases are currently under investigation by the Italian Parliament. Recently, investigators have uncovered a new lead after many years. This lead centers around a recently discovered secret passage. It is hoped that this new information may finally shed light on what happened to Gregori, and potentially, Orlandi as well. The discovery has the potential to significantly alter the understanding of the case.
